What is the main purpose of the Financial Conduct Authority's firm systematic framework?

The primary purpose of the Financial Conduct Authority's (FCA) firm systematic framework is to ensure that customer interests are at the heart of business operations. This involves establishing principles and standards for firms to follow, to promote fairness, transparency, and accountability in financial services. By focusing on the welfare of consumers, the FCA encourages firms to adopt ethical practices and make decisions that prioritize customer needs.

While the other options address certain aspects of a firm's responsibilities, they do not capture the overarching aim of the FCA's framework. For instance, calculating tax liabilities is a separate function that falls under taxation regulations rather than consumer protection. Similarly, while assessing a firm's financial security rating is important, it is part of a broader risk assessment rather than the central goal of the framework. Setting eligibility criteria for approved persons pertains to governance and regulatory compliance but does not encapsulate the primary focus on consumer interests that drives the FCA's initiatives.
