The Financial Services Authority (FSA) was a regulatory body in the United Kingdom responsible for overseeing financial markets and firms. Established in 2001, its main goal was to protect consumers, maintain market integrity, and promote competition within the financial services sector. The FSA regulated banks, insurance companies, and investment firms to ensure they operated fairly and transparently. In 2013, the FSA was replaced by two new organizations: the Financial Conduct Authority (FCA) and the Prudential Regulation Authority (PRA). The FCA focuses on consumer protection and market integrity, while the PRA supervises banks and insurers to ensure their stability. This restructuring aimed to enhance the effectiveness of financial regulation in the UK.
