The Financial Services Authority (FSA) was a quasi-judicial body accountable for the regulation of the financial services industry in the United Kingdom between 2001 and 2013. It was founded as the Securities and Investments Board (SIB) in 1985. Its board was appointed by the Treasury, although it operated independently of government. It was structured as a company limited by guarantee and was funded entirely by fees charged to the financial services industry.
