Two main characteristics differentiated post-war British monetary analysis and management from those of most other developed countries. First, monetary targetry in the UK focused primarily on a broad money aggregate, M3 or £M3, comprising both sight (demand) deposits and time and savings deposits, equally weighted.Footnote 1 This contrasted with procedures in most other countries, which focused on a narrow monetary aggregate, such as M1, and gave either no weight, or less weight (as in Germany) to time and savings deposits.Footnote 2 British practice in this respect derived from longstanding behaviour whereby UK banks have traditionally allowed clients to make payments by drawing on their time deposits. The dividing line in the UK between (monetary) sight deposits and (quasi-money) time and other deposits was therefore more porous than in most other countries. By the same token, and unlike in the USA and Germany, cash and liquidity ratios were applied equally to all deposits.
UK private sector residents’ bank deposits in this period comprised the bulk of total bank liabilities, which must equal bank assets.Footnote 3 Focusing on a broad monetary aggregate led naturally to the second distinguishing characteristic of British monetary analysis and management − the credit counterparts approach – since the broad monetary aggregate is the counterpart of bank lending to the public, private and overseas sectors. In contrast, focusing on a narrow monetary aggregate in a flow-of-funds framework would have required assessment of likely flows between sight and other kinds of bank deposits, which were neither easily predictable nor easily subject to any official control.
The credit counterparts approach contrasted with the dominant academic theory of the determination of the money stock from the late 1930s, which focused on the money multiplier. This linked the money stock, broad or narrow, to the monetary base provided by the central bank and two ratios: the public's currency/deposit ratio, and the banks’ reserve/deposit ratio (Phillips Reference Phillips1920; Keynes Reference Keynes1930; Meade Reference Meade1934; Sayers Reference Sayers1938). Like the flow-of-funds approach, this was derived from a statistical identity, and in neither case could one assume a direction of causation. The main problem with the money multiplier approach has been that almost always, almost everywhere, central banks have chosen to set an official short-term interest rate, not a fixed quantity of base money (that is, prior to reaching the Zero Lower Bound). Consequently, central banks must passively provide just that quantity of base money consistent with the officially chosen short-term interest rate. Therefore, the money multiplier actually works in reverse, determining the monetary base with (broad) money growth influenced, inter alia, by the officially chosen level of short-term interest rates (Goodhart Reference Goodhart2009, Reference Goodhart2016, Reference Goodhart2017; Goodhart, Bartsch and Ashworth Reference Goodhart, Bartsch and Ashworth2016).
It would have been physically possible for any central bank, including the Bank of England (the ‘Bank’), to reverse engines and control the quantity of base money, allowing (short-term) interest rates to fluctuate as they willed. But given banks’ inelastic demand for base money, fluctuations would most likely have been volatile. In view of the UK's high post-war debt ratio, the fragile structure of the gilts market, with the jobbers (the market makers) being too lightly capitalised, and the need to maintain investor confidence, the authorities, especially the Bank but also HM Treasury, reacted strongly against proposals for monetary control that put financing of the national debt, and the existing structure of money and gilts markets, at risk.
After World War II, British banks were large holders of (mostly short-dated) public sector debt. It was apparent to any careful observer that, if the Bank wanted to maintain a given level of short-term (Treasury bill) rates, the banking system could generate whatever reserve base it wanted. But academic theories, even when wrong, are hard to kill off. The then doyen of British monetary economists, Richard Sayers, retreated from espousing a cash ratio theory to treating the liquidity ratio as the effective fulcrum for monetary control in subsequent editions of his textbook, Modern Banking.Footnote 4 But Bank officials were then just as leery about allowing (encouraging) gilt prices to fluctuate in an uncontrolled fashion (in the hope of managing net debt sales better), so in practice the liquidity ratio multiplier was just as analytically back-to-front as a cash ratio multiplier.Footnote 5 Nevertheless the possibility of some measure of ratio control (exerting pressure on the banks’ liquidity ratio with, for example, calls for Special Deposits) remained a concept that cropped up in the British authorities’ thinking from time to time.Footnote 6 There was often a degree of confusion in the Bank and Treasury between multiplier analysis (whether via the liquidity or cash ratio), which was taught almost universally in academia, and the flow-of-funds approach which was what the UK authorities, but not most academics, really believed.
We discuss the genesis of the flow-of-funds approach, then in its infancy, below. It was particularly attractive to the UK authorities because it focused on four main economic developments which the authorities regarded as crucial for policy. These were (1) the Public Sector Borrowing Requirement; (2) net sales of public sector debt to the non-bank public, which together, more or less, determined the residual bank lending to the public sector; (3) bank lending to the private sector; and (4) net overseas flows, whose statistical treatment was complex, as we show. If the authorities could control the first three (domestic credit expansion, DCE) then, assuming a stable demand for money function, net external flows and reserve accumulation could be controlled.
In practice none of these three components of DCE could be closely controlled. Once the annual budget had set expenditure plans and tax rates, public sector expenditures depended on how strictly the Treasury could hold the spending departments, and the local authorities and nationalised industries, to their prior plans, while tax receipts were endogenous to the economic cycle. The authorities were unwilling to force gilt sales onto a weak market, partly out of concern for the solvency of the jobbers, partly because they feared that expectations would be auto-regressive, and partly for fear of damaging longer-run confidence about the safety of investing in gilts. So gilt sales tended to come in bursts (at unpredictable times), interspersed with periods of much lower, or even negative sales.
That left the third major component, bank lending to the private sector. But such lending was not seen as elastic in response to the scale of variation that the authorities were prepared to countenance in official short-term rates, i.e. Bank rate, given the various factors, external and domestic, weighing on the Chancellor's interest rate decisions. All that meant in practice, during the years from 1945 until Competition and Credit Control in 1971, was that the authorities (led by the Treasury, unhappily followed by the Bank) would reach for directly applied ceilings on bank lending to the private sector whenever there was a perceived need for a check to domestic credit and monetary growth.
The International Monetary Fund (IMF), under the analytical direction of Jacques Polak, preferred a simpler (‘Western Hemisphere’) model based on the money multiplier approach. Faced with the UK authorities’ insistence that such a model was inappropriate for the UK, the Fund, after lengthy discussion described below, became prepared to work with the UK authorities within the context of a flow-of-funds model.Footnote 7 Indeed, the Fund insisted at the time of heavy UK drawing in 1969 that DCE, as defined above, could, and should, be limited and controlled.
By the end of the 1960s, the monetary authorities in the UK had firmly tied themselves to the joint position of focusing on a broad money target and using a flow-of-funds analysis for forecasting and (attempted) control purposes. This was not, of course, the end of the story. The expansion of the money stock in the years 1971–4 was more exaggerated in broad money (M3) than in narrow money (as recurred in 1980–1). This led British monetarists, and much of the Conservative Party, to focus on M3 as the underlying cause of the subsequent inflation in the mid 1970s, while it led some Bank officials from time to time to regard M1 as a truer measure of the ‘thrust’ of monetary policy.
Much of the history of the conduct of monetary policy during these years has already been set out, not least in the official histories of the Bank of England by Fforde and Capie (Fforde Reference Fforde1992; Capie Reference Capie2010). The particular contribution of this article lies instead in the detailed historical study of the largely statistical discussions between the Bank and the IMF, whereby the Bank eventually persuaded a reluctant Fund that monetary conditionality, and later targets (whether for domestic credit or the money stock), in the UK should be based on broad aggregates.
In April 1861, launching its inaugural half-yearly banking supplement, the Economist newspaper recommended that the ‘perfect Report of a Joint Stock Bank’ should state ‘what are the deposits, distinguishing between those held at call and those which are to be repaid only at the expiration of a certain stipulated notice’.Footnote 8 As René Higgonet points out, however, ‘most banks did not distinguish between current accounts and fixed deposits’ in the nineteenth century (Higgonet Reference Higgonet1957, p. 333). Even after the Economist first aggregated the banking data in October 1877, and began publishing monthly figures for (most of) the London joint stock banks from August 1891, it was difficult to distinguish current and deposit accounts.Footnote 9 As financial journalist Hartley Withers later explained: ‘if a customer wished to remove deposit funds immediately, very few bankers would refuse to permit him to do so’.Footnote 10 This remained the position in 1930 when the managing director of the Midland Bank, Frederick Hyde, explained to the (Macmillan) Committee on Finance and Industry:
We must bear in mind that our deposits are in a very considerable part payable on demand, and even those deposits that are fixed for a period may be payable on demand by arrangement with the depositor.Footnote 11
Nonetheless, considering ‘exact quantitative knowledge concerning the chief elements of the monetary and financial system’ to be ‘of the utmost importance’, the Macmillan Committee obtained, and published, a breakdown of current accounts (‘sums payable on demand’) and deposit accounts (‘sums payable after a date or notice’) at the ten London clearing banks and the six Scottish banks since 1919 (Macmillan Committee 1931, pp. 174, 283–95; Capie and Webber Reference Capie and Webber1985, pp. 259–60). On the Committee's recommendation, disaggregated data continued to be published, first in the Bank of England Statistical Summary and then in the Monthly Digest of Statistics, as well as the Economist.Footnote 12 The divide between current and deposit accounts remained porous, however. As Sayers pointed out in 1938:
banks will transfer balances from one of their own classes to the other without hesitation – they leave the distribution of deposits entirely in their customers’ hands. The banks decide the total volume of deposits; but the public, directly at least, decides the distribution between the Cash Deposits and Savings Deposit categories.Footnote 13
This remained the case after the standardisation of seven-day terms for deposit accounts in 1955 (Radcliffe Committee 1959a, paras 131–2; Wadsworth Reference Wadsworth1973, p. 125). In June 1958 the National Institute of Economic and Social Research included in its definition of the money supply ‘deposit accounts in the joint stock banks, the restrictions on transfer being such that the accounts can be regarded as de facto transferable “without restriction”’.Footnote 14
In 1861, the Economist also warned against judging a bank primarily by the adequacy of its capital. Rather:
we should add together all the liabilities of the bank – its circulation, its drafts, and its deposits: see what the total is carefully; and then we should compare it with the amount of cash, loans to bill brokers, Government securities, and other immediately tangible and convertible assets which the bank has in hand. If the available money bears a good proportion to the possible claims, the bank is a good and secure bank.Footnote 15
On the question of ‘the specific proportion between the cash reserve and the liabilities of the bank’ the newspaper refused to ‘lay down any technical or theoretical rule’. The cash ratio must be allowed ‘to vary in some degree with the nature of the bank's business’. Seventy years later, the Macmillan Committee largely agreed:
The monetary system of this country must be a Managed System – It is not advisable, or indeed practicable, to regard our monetary system as an automatic system, grinding out the right result by the operation of natural forces aided by a few maxims of general application and some well worn rules of thumb.Footnote 16
According to the Committee, the monetary authorities should manage the price level by changing ‘the quantity and terms of credit’ principally by adjusting Bank rate (‘a most delicate and beautiful instrument’).Footnote 17 As Sayers wrote in 1938, ‘the tendency nowadays is to regulate cash ratios not in the interests of bank liquidity but in the interests of central bank control over aggregate bank deposits’ – what officials referred to as the ‘Macmillan process’.Footnote 18 But unlike the US Federal Reserve, which required member banks to keep 6 per cent of their time deposits and 14–26 per cent of their sight deposits in cash, the UK monetary authorities did not differentiate between sight and time deposits (Sayers Reference Sayers1938, pp. 43–4 and 254–8). There was no incentive, from a reserves perspective, for British banks to steer customers towards deposit rather than current accounts.
The requirements of wartime finance forced what the Midland Bank identified as ‘a radical alteration of the “cause and effect” relation between bank cash and deposits’.Footnote 19 As government revenues fell short of current expenditures, (and after sales of British government securities to the non-bank public and foreign loans), the Exchequer was forced to borrow from the banks, largely in the form of bank purchases of additional Treasury Deposit Receipts and Treasury bills. The counterpart of such additional loans to the public sector was mainly higher private sector deposits (via government expenditure), which required the banks to maintain higher cash reserves to preserve their (informal) cash ratios.Footnote 20 To support the higher level of deposits necessary for increased government borrowing from the banks, the Bank had to supply more cash to the banks through open market operations. This was the reverse of the ‘Macmillan process’, with cash reserves now determined by the volume of aggregate deposits.Footnote 21
With the national debt peaking at 238 per cent of GDP after World War II and the banks extremely liquid, the authorities were forced to extend wartime financial repression. In 1946 the cash ratio was formalised with the clearing banks required to hold 8 per cent of their total deposit liabilities in notes, coin, and reserves at the Bank.Footnote 22 With the banks holding so many near-money assets, and the Bank prepared to monetise these on demand, there was no question of controlling lending via the cash ratio, a notion described as ‘risible’ by one former Bank economist.Footnote 23 In order to keep interest rates and the cost of government finance stable, the Bank continued to supply whatever cash the banks demanded.Footnote 24 In 1951, the cash ratio was supplemented with a request that the clearing banks hold 28–32 per cent of their total deposits in liquid assets: cash, money at call with the discount houses, eligible commercial bills, and UK Treasury bills.Footnote 25 These measures had little to do with prudential financial management. Nor were they attempts to regulate bank lending through the operation of a multiplier. As the Governor admitted in 1957, they were principally about directing the nation's savings into government debt so the Bank could avoid ‘a continual state of anxiety as to how the Government's requirements for finance for the following week were going to be met’.Footnote 26 When the liquidity ratio was formalised in 1951, the banks were ‘forced’ to switch about £500 million of Treasury bills for ‘serial funding stock’.Footnote 27 This reduced their liquid assets from 39 per cent of total deposits to 32 per cent (Radcliffe Committee 1959a, para. 406).
The liquidity ratio was consistent with the arrangements developed during the ‘cheap money’ period. These arrangements rested on three (non-statutory) agreements:
1. An informal, but effective, clearing bank cartel that fixed deposit and lending rates in return for a monopoly on the payments system. This was one of the factors that enabled the authorities to continue their direct repression of bank lending during times of strain.Footnote 28
2. A discount house/clearing bank agreement that gave the discount houses a virtual monopoly over the Treasury bill tender in return for an agreement not to compete with the clearing banks for deposits.Footnote 29 (The clearing banks financed the deposit houses with ‘money at call’ at a pre-agreed margin.)
3. A Bank/discount house agreement that the discount houses would cover the Treasury bill tender in return for a monopoly on the Bank's lender of last resort facilities.
In the post-war period, the goal was to maximise sales of government debt at minimal cost, while all the time maintaining the value of sterling. The authorities had to sell significant quantities of government debt simply to finance maturing stock before they could begin to tackle new Exchequer funding needs. Quite apart from the theoretical objections, shifting to a system that relied on more volatile interest rates to exercise control through a cash ratio would have imperilled the Bank's ability to finance the national debt, its primary function since its foundation in 1694. There seemed little point in risking a collapse simply to refashion the monetary infrastructure along neater theoretical lines.
In his 1956 Budget statement, Chancellor Harold Macmillan complained that ‘some of our statistics are too late to be as useful as they ought to be. We are always, as it were, looking up a train in last year's Bradshaw.’Footnote 30 Macmillan was partly referring to the forecasts that had preceded R. A. Butler's expansionary Budget the year before.Footnote 31 The subsequent boom had required a rigorous credit squeeze with Butler requesting a ‘positive and significant’ reduction in bank advances just three months after his Budget.Footnote 32 In March 1956 the high-level civil service Economic Steering Committee asked the Working Party on Statistics for Employment Policy to consider whether existing banking and financial statistics were adequate for the formulation and measurement of monetary policy.Footnote 33
While the impetus came from Ministers, officials recognised in 1956 that better financial statistics might contribute ‘raw material for “flow of fund” analyses’.Footnote 34 The Bank described the technique as:
a logical extension of the more familiar system of national accounts: it covers the transactions in financial assets and liabilities which accompany income and expenditure…by mapping out the financial transactions by sectors, it draws attention to the ways in which such aggregates as an increase in the money supply or, more generally, in liquidity can be built up. (Bank of England 1972, p. 7)Footnote 35
National income statements aggregate flows during a particular period; flow-of-funds matrices ‘set out the particular routes along which funds pass between the sectors’ capital accounts in a particular period’ (Bank of England 1972, p. 10). As Andrew Bain points out, while the matrices provide no behavioural explanations of why funds may be flowing in a particular direction, they forge a link between monetary policy and demand management (Bain Reference Bain1973, p. 1055).Footnote 36
By November 1956, the Central Statistical Office (CSO) had produced rudimentary flow-of-funds matrices.Footnote 37 Within the Bank, John Fforde described this as ‘pioneer work’ which would shed further light on the growth of the money supply, an increasing Treasury preoccupation under Peter Thorneycroft (Chancellor from January 1957) since ‘the change in government borrowing from the banking system is then combined with the change in private borrowing from that system to give us the change in money supply’.Footnote 38 Deputy Governor Humphrey Mynors commented ‘this looks to me like a Sputnik, not yet at the moon, but navigating in a part of the universe which man has not yet reached. Surely capable of development?’Footnote 39 In February 1958 Economic Trends introduced graphs of the money supply defined as ‘Total of (1) deposits at London Clearing Banks and Scottish Banks (less collections and identifiable items in transit), (2) deposits at the Bank of England (other than “Bankers”), (3) currency in circulation with the public’.Footnote 40 This was also the definition used in the 1958 Economic Survey.Footnote 41
The Working Party's inquiry was overtaken by the Committee on the Working of the Monetary System (the ‘Radcliffe Committee’), announced in April 1957 in response to the failure of tighter monetary policy to contain the Butler boom.Footnote 42 The Radcliffe Committee was equally enthusiastic about flow-of-funds analysis, defining the following objectives:
(i) to allow the framework of the financial structure within which monetary changes take place to be seen in more precise quantitative terms;
(ii) to give the earliest possible indication of the movement of liquidity and of the way in which monetary pressure on demand would be likely to take effect;
(iii) to give the earliest possible indication of the movement of demand in each part of the economy, and so enable the pressure of demand to be regulated satisfactorily. (Radcliffe Committee 1959a, para. 798)
The Committee believed that financial statistics should be ‘capable of being fitted together so as to show the total movement of funds, not merely the flow through individual financial institutions’ (Radcliffe Committee 1959a, para. 865). As the Bank noted: ‘The Radcliffe Committee's preoccupation with liquidity leads them to give particular attention to the flow of short-term funds and to the statistics of banks as “the largest suppliers of liquid funds”.’Footnote 43 The Committee requested data on ‘the current flows of funds from the financial sector as a whole to the other major sectors of the economy…[since] one of the principal objects of monetary analysis [was] to examine the interactions of these sectors on one another through financial transactions’ (Radcliffe Committee 1959a, paras. 808–9). Given the importance of ‘clean’ data to flow-of-funds analysis, the report gave detailed statistical recommendations, based largely on evidence submitted by the National Institute of Economic and Social Research (Alford Reference Alford1986, p. 61). These chimed with the earlier work of the Working Party on Statistics for Employment Policy.Footnote 44
Annual flow-of-funds accounts were produced from 1960.Footnote 45 In September 1962 Economic Trends explained that ‘the comprehensive nature of national income accounts and their analysis into sectors have made these a suitable framework for presenting the main “flow” items and for linking the “real” and financial accounts’.Footnote 46 This was reflected in the sector classifications: Public Sector, Private Sector, and Overseas Sector.Footnote 47 As the authors explained:
In the United Kingdom it is intended to avoid changing the present conventions in the national income accounts, such as those affecting sector boundaries and the definitions of the gross national product, when adding the extra financial tables to the national income accounts – at least until considerable practical experience with the new figures has been obtained. (Economic Trends, September 1962, p. xi).
‘Scattered’ flow-of-funds matrices were published in September 1963 in Financial Statistics and the Quarterly Bulletin, and were ‘centralised’ in the 1964 National Income Blue Book (Alford Reference Alford1986 p. 36, n. 2; Bjork and Offer Reference Bjork and Offer2013, p. 5). There was quarterly analysis in Financial Statistics from December 1964 and the Quarterly Bulletin from March 1965, with more detailed analysis and a new table setting out ‘the factors determining changes in the money supply’ in Financial Statistics from June 1966.Footnote 48 By 1968 the flow-of-funds matrices were being used to prepare financial forecasts to test the assumptions underlying the national income forecasts (Berman and Cassell Reference Berman and Cassel1968, p. xiv). In March 1969, the prospect of tougher IMF loan criteria generated ‘severe pressure for earlier financial information in the near future’.Footnote 49
The IMF had been developing its own flow-of-funds approach based on a narrower definition of the money supply (Dorrance Reference Dorrance1955; Polak Reference Polak1959; Polak and Boissonneault Reference Polak and Boissonneault1960). In 1956, director of research Jacques Polak defined ‘money’ as ‘an entry, or combination of entries, on the liability side of the balance sheets of the banking system’ (Polak Reference Polak1957, p. 11). Recognising the arbitrariness of the distinction between current accounts and deposit accounts in countries such as the UK, he nonetheless concluded, from a theoretical perspective, that current accounts and the liabilities of the central bank were ‘monetary liabilities’ while deposit accounts (‘quasi money’) were not. On the asset side, he divided the ‘quantity of money’ in two: ‘money of external origin’ – the (net) foreign assets of a country's banking system; and ‘money of domestic origin’ – the domestic assets of a country's banking system. His analysis proceeded on the assumption that the income velocity of money was constant, and that ‘domestic credit expansion’ was exogenous, that is, ‘credit expansion is subject to the responsibility of the banking system’.Footnote 50 From there followed his assertion that excessive domestic credit expansion was the primary cause of balance of payments deficits. These assumptions would put the Fund on a collision course with the UK monetary authorities, accustomed to treating bank credit as a passive variable that responded to the short-term requirements of the public and private sectors, and who believed the velocity of circulation to be unstable (Radcliffe Committee 1959a, para. 391).
The Fund had been publishing the current and deposit accounts of the London clearing banks in International Financial Statistics (IFS) since 1948.Footnote 51 In 1955, with some fanfare, it relaunched IFS with a new ‘Monetary Survey’, recasting and standardising the financial statistics of twelve member states (although not yet the UK) to provide a ‘ready-made analysis’ that would reveal ‘the proximate causes of changes in the money supply’.Footnote 52 The UK money supply was defined as currency and the current accounts (but not deposit accounts) of the London clearing banks.Footnote 53 While there had been some communication over the new presentation, the Bank was perturbed:
We were…very surprised and disturbed to see them burst into print in the January issue of IFS with an incomprehensible economic introduction and the implied promise that this form was to be extended to the UK. The Fund Staff have clearly badly jumped the gun, and it is now mainly a question of finding the best way of undoing the damage.Footnote 54
These were the opening manoeuvres in what Bank officials later referred to as the ‘Seven Years War’ over UK monetary statistics.
The first problem was doctrinal, reflecting the British emphasis on liquidity rather than the money supply. If the money supply was relatively unimportant to demand management, figures purporting to identify the causes of changes in the money supply could be misleading.Footnote 55 There were also a host of technical problems with the Fund's presentation of the UK monetary statistics. The first involved the treatment of the Exchange Equalisation Account (EEA), set up in 1932 to manage the UK's gold and foreign currency reserves following sterling's exit from the Gold Standard (Howson Reference Howson1980). While day-to-day management lay with the Bank, ownership of the account lay with HM Treasury (the public sector).Footnote 56 The EEA was financed primarily through the issue of Treasury bills; an influx of reserves would usually require the authorities to sell more Treasuries, that is, a rise in the reserves was generally associated with an increase in the government's gross liabilities.Footnote 57 The impact on the money supply would depend upon who bought the Treasury bills.Footnote 58 If the commercial banks bought them, their liquidity ratios would rise (although their cash ratios might fall) and it is likely that the broad money supply would increase; if the non-bank private sector bought them, bank lending and the broad money supply would probably be less affected.
In its efforts to standardise the UK's statistics with those elsewhere, and to forge a reliable link between the balance of payments and the monetary sector, the Fund wished to include the EEA in the banking sector of the UK economy (‘as if it was financed by the Bank’).Footnote 59 IMF officials treated sterling payments from the government to the EEA (to finance increases in the reserves) as reductions in its net liabilities to the banking sector, i.e. a rise in the reserves implied a decrease in the government's gross liabilities.Footnote 60 A change in the reserves might also produce a change in the non-bank private sector's holdings of Treasury bills with little impact upon the government's liabilities to the banking sector. Also, with the Bank holding other sterling area countries’ reserves and foreigners’ balances for international trade, the EEA could fluctuate for reasons that had little to do with the UK economy. The Fund's approach might identify a monetary stimulus from the government to the banking system where none had taken place. As adviser to the Governors (and former IMF assistant director of research) Maurice Allen pointed out, ‘the IFS presentation does not correspond to the complexities of our overseas banking activities and can produce nonsense results when applied to UK figures’.Footnote 61
There was a related problem with the Fund's proposed treatment of the Bank's Issue Department. Elsewhere, issue departments largely confined their activities to issuing bank notes and passing the proceeds on to their governments so could logically be treated as part of the public sector. But the Bank of England's Issue Department also managed the national debt. This required the department to hold significant and changing amounts of British government securities. As a consequence, the Fund proposed to treat the Issue Department as part of the UK banking sector. But in the UK, monetary policy was debt management policy.Footnote 62 The authorities influenced the monetary system mainly through operations on public sector debt, with Bank rate directed primarily towards the exchange rate. The Bank described the Fund's proposal to place its debt management operations in the banking sector as leaving the monetary authorities looking like ‘Hamlet minus [the] Prince’.Footnote 63 Furthermore, placing the Issue Department in the banking sector would require the authorities to reveal the extent of the Bank's holdings of British government securities.Footnote 64 This was market-sensitive information that might hinder the Bank's ability to execute monetary policy.Footnote 65
A further problem was that the information required to show the origins of changes in the money supply would require greater disclosure from all sectors comprising the ‘monetary system’ as defined by the Fund: the Bank, the clearing banks, and ‘other financial institutions’ such as the building societies, the Trustee Savings Bank and the Post Office Bank. This would place an unwelcome statistical burden on the entire financial sector. The 1946 Companies Act permitted the clearing banks to withhold information about their reserves, which they tended to keep in ‘Other Accounts’. The IMF's new approach might reveal information about these reserves, especially embarrassing for the large clearing bank rumoured to have suffered heavy losses between 1947 and 1951.Footnote 66 As Maurice Allen pointed out, ‘for the IFS to be in a position to give the analysis of the proximate causes of the change in money supply, they would need to know more than we would want to tell them’.Footnote 67
Despite the Bank's preparedness to ‘go into action’ with the IMF's Statistics Division, a lack of support from other countries necessitated a truce which involved the Fund publishing the UK statistics in the pre-1955 format until both sides could agree a mutually acceptable format.Footnote 68 After several further engagements, a delay while the Radcliffe Report's statistical recommendations were implemented, and a ‘pleasant and profitable visit’ to Washington by the Bank's head statistician, the Bank declared victory when the Fund's statisticians fell in to line with the UK presentation of monetary statistics in the August 1962 IFS.Footnote 69 The EEA and the Issue Department were excluded from the banking sector, which was defined as per the Bank of England Quarterly Bulletin. Current and deposit accounts were both treated as ‘money’. As the Bank's deputy head of statistics noted:
I am surprised that the IMF have capitulated on the current/deposit A/C battle. I would have thought that any understatement of ‘Money’ that would arise from excluding Deposit Accounts (and, with them, some balances which are in practice operated on as demand deposits) would be considerably less than the overstatement arising from inclusion of Deposit accounts (and, with them all the truly savings accounts) – i.e. that Deposit Accounts contained more savings accounts than disguised deposit accounts. However, the fund having accepted defeat, it would be silly to turn the board around and start the game all over again.Footnote 70
The Fund had finally acknowledged what Walter Bagehot had known a century before, that ‘the distinction between current and deposit accounts in the UK is not as marked as implied by the treatment of one as Money and the other as Quasi-Money; deposit accounts are in practice frequently treated by the holders as indistinguishable from current accounts’.Footnote 71
If the dispute with the Fund had been confined to the presentation of UK monetary statistics, it might have remained ‘a statisticians’ wrangle’.Footnote 72 However the UK was fast becoming the largest single user of IMF facilities. In December 1956, the UK drew $561.47 million and secured an additional $738.53 million stand-by facility.Footnote 73 There were further drawings in August 1961 ($1,500 million), November 1964 ($1,000 million) and May 1965 ($1,400 million).Footnote 74 Initially these facilities came with few conditions attached, partly because UK officials could invoke sterling's reserve currency status.Footnote 75 As one Treasury official noted in 1959, ‘it would be repugnant to the dignity of a country of the UK's status’ to have conditions applied to IMF loans.Footnote 76 This was not the case with less-developed nations where, to increase the probability of successful economic adjustment (and the IMF's chances of getting its money back), loans were granted ‘only after substantial investigation of the would-be borrower's macroeconomic policies and the collaborative development of a recovery program’ (Finch Reference Finch1989, p. 9). By 1958, the Fund had phased loans to Turkey, Yugoslavia, Bolivia, Haiti, Paraguay, Argentina and Chile with the implementation of financial programmes. These rules for developing nations were formalised in 1958 when the IMF's Executive Board recommended that Bolivia be denied access to its loan facility while it remained in breach of the agreed programme.Footnote 77 The performance targets included limiting central bank credit, chosen because the Fund believed the Bolivian central bank could control its balance sheet. This was the foundation for Polak's Western Hemisphere model.
The Western Hemisphere model was predicated on the theory that domestic credit creation was the primary source of balance of payments disequilibria. It was simple, designed for nations for whom the reliability and even existence of accurate financial statistics might be in doubt.Footnote 78 It was too simple for British officials who could continue largely to ignore it until May 1965, despite negotiating a succession of stand-by agreements and the large drawings of August 1961 and November 1964. In May 1965, however, with the 1964 stand-by fully drawn and $1.1 billion drawn from a $3 billion facility provided by consortium of central banks falling due, the UK government requested an immediate $1.4 billion loan that would take it beyond its quota.Footnote 79 A drawing of this size required the Fund to activate the General Arrangements to Borrow negotiated two years earlier with its members. Given the more ‘classical’ monetary views held by a number of European central bankers, this meant tougher conditionality.
The May 1965 IMF mission was led by Polak. While he conceded on a ceiling for Bank of England credit to the government, he insisted that ‘estimates’ for the growth of clearing bank lending and deposits be included in the Letter of Intent.Footnote 80 While this did little to endear him to UK officials, it is noteworthy that Polak was prepared to target commercial bank lending and deposits rather than central bank lending. Previously, IMF performance criteria had almost always related to the central bank's balance sheet.Footnote 81 Nonetheless the Fund recognised that the choice of ceiling depended on the characteristics of each country's monetary system – ‘a ceiling applying to the banking system as a whole may be preferred because its relationship to other economic variables, and policy decisions, is clearer’.Footnote 82 This sold the pass on conditionality attached to the growth of the monetary base. And having conceded in 1962 that there was less distinction between current and deposit accounts in the UK than elsewhere, the pass was sold on conditionality applied to the growth of ‘narrow money’.
Access to the 1965 facility was not phased according to performance criteria. Nonetheless, Chancellor James Callaghan undertook to consult the Fund ‘should any major shift in the direction or emphasis of economic or financial policy as stated in this letter become desirable during the period in which Fund holdings of sterling are in excess of 125 per cent of the quota’.Footnote 83 Since financial policy included ‘an increase in advances to the private sector by the London clearing banks in the year ending March 1966 of not more than 5 per cent (£230 million), and…an increase in their deposits in the same proportion (about £400 million)’, the IMF had imposed loose monetary conditionality on the UK, albeit on a definition of UK officials’ choosing.Footnote 84 As Polak explained to the Fund's Executive Board:
In our discussions we have put primary emphasis on the importance of the Government taking a view as to the appropriate amount of credit expansion. We considered this more important than the introduction of one specific measure of control or another.Footnote 85
On 17 November 1967, the British government finally admitted defeat in the defence of sterling at the post-1949 Bretton Woods parity of $2.80. The Fund's managing director, Pierre-Paul Schweitzer, reacted ‘without surprise and with little comment’, despatching a mission led by its head of fiscal affairs, Richard Goode, to London armed with a series of policy recommendations.Footnote 86 These included a £250 million limit on Exchequer borrowing from the banking system and a £500 million ceiling on domestic credit expansion.Footnote 87 These, the Fund estimated, would be required to generate the desired current account surplus over the next year. Goode immediately ran into trouble. The Chancellor was naturally concerned about the political criticism IMF-imposed performance criteria would attract, both from the Conservative opposition and from his own backbenchers.
Bank and Treasury officials’ concerns were more technical. They argued that if the market knew the authorities were missing an IMF target, they could be held to ransom, forced to pay a higher rate on the new gilt issues required to get Exchequer borrowing from the banking system and DCE back on track. The Issue Department's management of the national debt was perceived to be a fine art, not conducive to the blunt instrument of an IMF performance target. Moreover, as Maurice Allen pointed out, it was impossible to estimate in advance how much the EEA would have to borrow from the banks to finance an influx, especially given sterling's reserve currency status.Footnote 88 Deputy Governor Sir Maurice Parsons also reminded Goode that British banking was traditionally reliant on overdrafts, which could be drawn at the convenience of the borrower. This made it very difficult for the clearing banks to predict the size of future lending and, therefore, their reserves at the Bank. In short, the size of the Bank's balance sheet, and DCE, simply could not be forecast with any degree of precision.
We tried to explain that it was wrong to apply to the UK with its sophisticated monetary system principles and practices which might be perfectly alright for the Argentine or a lesser-developed African country. But even after long sessions, we failed to convince Goode and we therefore agreed, in the course of the final session between [Permanent Secretary to the Treasury] William Armstrong and Goode, that between now and February we would have a seminar – presumably in London – which could discuss all these points thoroughly without being up against the clock, as we were in preparing the Letter of Intent.Footnote 89
While Armstrong was prepared to forego an IMF loan rather than accept DCE conditionality, the Bank's Jeremy Morse conceded that ‘as far as the Bank was concerned we would be ready to concede a “warning light” ceiling for money supply or for bank credit to the public sector the reaching of which would provoke immediate consultations with the Fund’.Footnote 90 While this was little advance on the loose conditions included in the May 1965 Letter of Intent, it helped to extricate the two sides from ‘the familiar rut for UK–IMF dialogue about our monetary objectives’.Footnote 91 After agreeing a form of words on the Exchequer borrowing requirement, the Fund conceded, once again, on the monetary target. As Maurice Allen noted:
the Mission offered us several different ways of binding ourselves to be good – sterilising the sterling receipts of EEA; varying the money supply ceiling up or down as the EEA went up or down, etc. Eventually, when they saw that we would not allow negotiations to be held up while we argued out at length such fundamental issues of principle, they accepted a modified version of Sir William Armstrong's draft mentioning the ‘expectation that…the growth of the money supply [on our definition] will be less in 1969 (sic) than the present estimate for 1967 both absolutely and as a proportion of GNP’.Footnote 92
The ‘present estimate’ for 1967/68 was £1.123 billion, or about 8½ per cent of the broad money stock.Footnote 93 As head of the Economic Service, Sir Alec Cairncross later pointed out, Armstrong ‘knew that the borrowing requirement was more important to [the IMF] than the credit ceilings’ (Cairncross Reference Cairncross1997, p. 254). The ‘fundamental issue of principle’ would be discussed at a future date, outside the pressurised atmosphere of the loan negotiation. But the British had succeeded in keeping to their broad definition of the money supply.
The next engagement was the ‘DCE seminar’, proposed by Armstrong, which finally took place in October 1968.Footnote 94 The IMF team was led, once again, by Polak. The terms of reference were: ‘to examine the theory of the relationships of financial factors on the national income and balance of payments, and the implications of these relationships for the techniques of economic forecasting’ (less formally, ‘to strengthen the position of those in London who regard financial programming as a useful tool of policy’).Footnote 95 On the first day the seminar considered two papers which defined ‘money’; one from the Bank, the other from the CSO.Footnote 96 Both were in line with the UK's traditional broad definition. The Fund conceded that ‘what was important was to choose a definition which covered all points at which money could be injected into the system and which was not misleading as an indicator’.Footnote 97 In any event, ‘their prime concern was not with the money supply as such’; it was with domestic credit expansion – the topic of the second day's discussion. Polak explained:
the critical monetary factor in the forecasting process was domestic credit expansion. Preliminary figures could first be set (be it as forecasts or targets) for GNP and the balance of payments. Then, on the assumption of a stable income-velocity of circulation, a forecast could be made of the money supply. From the balance of payments (change in external assets) and money supply forecasts thus obtained, the figure for domestic credit expansion could be derived. The latter in turn could be regarded as a first approximation to the additional spending likely to be generated as a result of monetary factors.Footnote 98
There was ‘extended discussion’ on the need to identify the source of the credit impulse. There were also considerable doubts expressed about the stability of the income-velocity of circulation, unsurprising at a seminar chaired by a member of the Radcliffe Committee (Sir Alec Cairncross) that had declared this to be ‘potentially infinite’ with another of its witnesses (Nicky Kaldor) in attendance. The principal disagreement, however, was whether the authorities should be looking at an aggregate measure such as DCE or its components. When asked what the UK reaction to an unforeseen increase in the money supply would be, Cairncross replied ‘it would surely be prudent to investigate the reasons for it closely before taking any action beyond perhaps some upward adjustment in interest rates’.Footnote 99
There was less dispute over which measure of money should be used. Summing up on the final day, Polak conceded that ‘the sensible course seemed to be to choose that definition of the money supply which gave the best correlation with money income and interest rates, and to extend the authorities’ control to include all those institutions whose liabilities fell within this definition’.Footnote 100 He had earlier noted that ‘for the purposes of monetary policy, it was interesting to study what spectrum of assets gave the best correlation with GNP and interest rates’.Footnote 101 Unbeknown to Polak, the Bank had already decided to do precisely this. Notwithstanding the broad money supply definition presented to the Fund, and deployed (with minor variations) in official publications since 1958, there remained within the Bank ‘a variety of views about the money supply’.Footnote 102 Chief Cashier John Fforde concluded it was time for a review (Capie Reference Capie2010, pp. 452–9).Footnote 103 Thus was born the Money Supply Group, comprised of Kit McMahon, Leslie Dicks-Mireaux, Andrew Crockett and, newly arrived from the London School of Economics, Charles Goodhart. This marked the onset of a fertile period of monetary research within the Bank, mirroring the theoretical investigations underway in academia. The group's work, however, was delayed by Chancellor Roy Jenkins’ acceptance of DCE performance criteria in May 1969. The 1965 and 1966 drawings from the Fund were falling due and, with the current account taking an inexorably long time to recover, the Bank had insufficient dollar reserves to repay. There was little alternative to another stand-by arrangement. In response to developing nations’ protests about the lack of strict conditionality attached to the UK's 1967 loan, the Fund had harmonised its stand-by criteria the previous September. There was little doubt that further assistance would require a DCE ceiling.Footnote 104 While detailed negotiations had to wait until after the April 1969 Budget, to avoid giving the impression that the IMF was dictating policy, a team of Bank and Treasury officials was despatched to Washington in February to sound out the Fund.
To some UK irritation, the Fund initially suggested a ceiling on the Bank of England's gross domestic assets, before retreating to ‘the concept of domestic credit of the banking system as set out in the monetary survey of IFS’.Footnote 105 As the Bank's Jasper Hollom pointed out, ‘the broad lines on which the application of the Fund's concept to the UK should be based were agreed without much difficulty’.Footnote 106 This may have been aided by pressure from the managing director who, in discussion with UK officials over the ceiling, admitted that ‘the UK “must agree to something”.Footnote 107 But Schweitzer seemed flexible on what the ‘something might be’. The Treasury's Frank Figgures explained that a ceiling based on the broader aggregate would make the Chancellor's job of presentation much easier. With some minor modifications (and despite their own equations showing a more robust relationship between narrow money and income), ‘the Fund were perfectly content’.Footnote 108
There remained the thorny question of where to set the DCE ceiling. This involved some ‘hard discussion’, a trip by Financial Secretary Harold Lever to Washington, and a compromise whereby the performance criteria would be a commitment on the part of the UK's Executive Director at the Fund, rather than the Chancellor. This allowed Jenkins to say ‘honestly that he had not committed to any performance criteria which the Fund staff might enumerate’.Footnote 109 And instead of a breach of the ceiling triggering a visit from the Fund, Jenkins agreed to three further surveillance missions. These would take place regardless of the DCE outcome. As the Economist pointed out, ‘the most important feature of Mr Jenkins's letter of intent to the International Monetary Fund is the thinness of the fig leaf that has been stretched over the trigger clause’.Footnote 110 To further placate his critics, Jenkins pretended that DCE was a British invention. This created an unwelcome diversion for Bank and Treasury officials, forced to justify an aggregate initially designed for less developed nations that none of them believed had much relevance for the UK. As Goodhart explains: ‘to protect British amour propre there had to be some pretence that we, in the UK, had thought up this wonderful new wheeze, rather than had it foisted upon us, out of weakness, by the IMF’ (Goodhart Reference Goodhart and Mizen2003, p. 25). Articles by Bank and Treasury officials in 1969 studiously avoided the suggestion that DCE was anything other than a British initiative.Footnote 111 The pretence worked, with British journalists and American observers taken in (Capie Reference Capie2010, p. 456).
In 1982, John Fforde wrote:
Specific intermediate targetry was…first introduced in the United Kingdom when standby facilities were negotiated with the Fund following the devaluation of sterling in 1967…The requirements of the IMF fitted readily into the established flow-of-funds accounting matrix and could thereby be made analytically consistent and visibly related.Footnote 112
In 1969 the IMF imposed a DCE ceiling on the reluctant British authorities (after insisting upon a money supply objective in 1967), but it was a broad variant that fitted longstanding British characteristics. Specifically, it reflected the porous divide between current and deposit accounts. A narrow definition, more attuned to the IMF's Western Hemisphere model would have required root and branch overhaul of, inter alia, British banking, monetary policy, management of the national debt and the currency reserves, and national accounting conventions. Faced with British intransigence and the need to preserve the Bretton Woods system, the Fund was pragmatic in the choice of aggregate, albeit after losing a ‘Seven Year's War’ with the Bank's statisticians. Britain entered the economically turbulent 1970s with the focus of monetary analysis and management on broad money with its link to fiscal policy through the credit counterparts. This approach would reach its apogee in the Thatcher government's 1980 Medium-Term Financial Strategy, with its four-year series of declining £M3 target ranges and deficit ceilings.
