The South Sea Bubble occurred in 1720, and it centred on the South Sea Company that was formed in 1711 as a public-private partnership to manage and consolidate British debt. The company earned exclusive rights to supply African slaves to the ‘South Seas’ region, which is now Central and South America. This deal promised to be very lucrative and money-spinning, attracting all rungs of society to seek a slice of the cake. By August 1720, share prices of the company hit highs of above £1,000, but just a month later, in September 1720, the bubble burst, and prices tumbled to lows of below £150. The stock prices never recovered above that level until the company was abolished much later in 1858.
