An Act for better securing certain Powers and Privileges intended to be granted by His Majesty by Two Charters for Assurance of Ships and Merchandizes at Sea, and for lending Money on Bottomry; and for restraining several extravagant and unwarrantable Practices therein mentioned.
The Bubble Act 1720 (also Royal Exchange and London Assurance Corporation Act 1719)[1] was an act of the Parliament of Great Britain passed on 11 June 1720 that incorporated the Royal Exchange Assurance Corporation and London Assurance Corporation, but more significantly forbade the formation of any other joint-stock companies unless approved by royal charter.
Its provisions were extended later by the Bubble Schemes (Colonies) Act 1740 (14 Geo. 2. c. 37)[2] to include its colonies, particularly Massachusetts.[3]
Various motivations have been suggested for the act. They include the desire to prevent the speculation that produced the contemporary South Sea Bubble, an attempt to prevent smaller non-charter companies from forming and so reduce the importance of Parliament in regulating businesses; or the South Sea Company itself wanting to prevent other bubbles from forming that might have decreased the intensity of its own.[5]
Recent scholarship indicates that the last was the cause: it was passed to prevent other companies from competing with the South Sea Company for investors' capital.[5][6][7]
An Act to repeal so much of an Act passed in the Sixth Year of His late Majesty King George the First, as relates to the restraining several extravagant and unwarrantable Practices in the said Act mentioned; and for conferring additional Powers upon His Majesty, with respect to the granting of Charters of Incorporation to trading and other Companies.
In fact, the act was passed in June 1720, before the peak of the bubble. The act was partially repealed in 1825 by the Bubble Companies, etc. Act 1825 (6 Geo. 4. c. 91).[8] The residue of the act was repealed in 1901.[9]
R v Cawood (1790) 2 Ld Raym 1361, 92 ER 386 (1 January 1790) - the only prosecution brought under the Act which, according to L.C.B. Gower, "decided nothing of importance".[10]
