This chapter outlines the history of previous institutions that created forms of capital in Europe, including land, dowries, banks, bills of exchange, and government debt. It examines the reasons why the system of informal oral credit, as it had developed over the previous 100-odd years, began to be criticised during the Commonwealth period. Many authors started to claim that it was both inefficient and an obstacle to economic growth. Many pamphlets were published containing proposals of different sorts of banks, which would issue paper currency to speed up circulation. Some of these were based on previous European examples. The nature of these proposals is examined, together with a summary of how they related to the creation of the Bank of England. Its establishment is normally seen as the successful outcome of this debate, but in fact it was not primarily created as an institution to expand the supply of credit, but to help fund the government debt. The increasing cost of the War of Spanish Succession did, however, result in the issue of things like Exchequer or Treasury bills, as well as South Sea and Bank stock to fund the war. The last part of the chapter focuses on the significant effect these multiple forms of paper currency had on liquidity within London.
