The Financial Conduct Authority is the UK's conduct regulator for financial services firms and financial markets. It was established in 2013, when the Financial Services Authority was split into two bodies: the FCA took responsibility for conduct and consumer protection, while the Prudential Regulation Authority assumed oversight of systemic and prudential risk. The FCA is accountable to HM Treasury and to Parliament, but operates independently of government on a day-to-day basis. It is funded primarily by levies on the firms it authorises.

The FCA oversees tens of thousands of firms, ranging from retail banks and insurers to investment managers, consumer credit providers, and, increasingly, cryptoasset businesses. Its remit has expanded materially since inception, absorbing responsibility for consumer credit regulation from the Office of Fair Trading in 2014 and taking on a growing role in digital assets and financial promotions online. The Senior Managers and Certification Regime, which the FCA administers alongside the PRA, has reshaped accountability structures across regulated firms.

For operators in financial services, the FCA is the single most consequential regulatory body in the UK market. Its enforcement actions, policy consultations, and supervisory priorities set the tempo for compliance investment, product design, and market entry decisions. The Consumer Duty, introduced in 2023, represents one of the most significant shifts in conduct expectations in a generation, requiring firms to demonstrate positive outcomes for retail customers rather than merely avoiding rule breaches. Watching how the FCA interprets and enforces that standard will define the operating environment for retail-facing financial services businesses for years to come.
