Which of the following best describes the role of the FCA?

The Financial Conduct Authority (FCA) plays a crucial role in maintaining the integrity and competitiveness of the financial markets in the UK. Ensuring effective competition is one of its primary objectives, as a competitive market ultimately benefits consumers through better products, prices, and services. The FCA actively monitors market behavior, enforces regulations, and takes actions against firms that may hinder competition, thereby fostering an environment where financial services can thrive. This involvement is essential to protect consumers and promote trust in the financial system.

The other options do not accurately represent the role of the FCA. For instance, managing the national banking system is typically under the purview of the Bank of England, which focuses on monetary policy and financial stability. Providing loans directly to consumers is a function of financial institutions rather than a regulatory body. Lastly, overseeing all household financial transactions extends beyond the FCA's scope, as its focus is more on regulation and market conduct rather than direct oversight of every consumer transaction.
