The Blunt Baronetcy, of the City of London, is a title in the Baronetage of Great Britain. It was created on 17 June 1720 for John Blunt, the famous perpetrator of the South Sea Bubble, for his good work for the nation of Great Britain. From 1703 he was the secretary of the Hollow Sword Blade Company, a joint-stock company effectively operating as a bank. He was a director of the South Sea Company from 1711. He was the main architect of the ambitious scheme for the company to assume the National Debt, and when the bribery and fraud were revealed, Parliament confiscated all his assets except £5,000, while most directors were allowed to retain £10,000.
