'The Bubble Act of 1720' (Officially titled the 'Royal Exchange and London Assurance Corporation Act 1719') was an
Act of the
Parliament of Great Britain (citation 6 Geo. 1, c. 18) that forbade all
joint-stock companies not authorised by
royal charter. While a common misconception is that the Act was passed to prevent a repeat of the
South Sea Bubble, in reality the Act was passed to prevent other companies from competiting with the
South Sea Company for investors' capital
[1]. In fact, the Act was passed in June 1720, before the peak of the bubble. The Act was repealed in 1825.
Under the terms of the act, the
Royal Exchange Assurance Corporation and the
London Assurance Corporation were granted charters to write
marine insurance. Until 1824 they remained the only joint-stock firms with such a charter.
