Central banks have enormous sums of money in various forms of investments. When claims are made either against the banks themselves, or against other governmental bodies, issues arise as to whether these assets can be attached, and made available to satisfy judgments. The article explains how central banks are treated in English law. It explains the special provision made in respect of their assets under the State Immunity Act 1978. There is wide immunity from attachment, though questions can arise as to the ownership of such assets. The UK legislation is, in some respects, wider than its counterpart, the US Foreign Sovereign Immunities Act 1976. Recent case law is described in which the English courts have recognised that the public responsibilities of central banks have to be taken account of when determining the extent of their liability to attachment.
