Both the substance of consumer protection rules and their enforcement are complementary to prudential supervision. Poorly designed financial products and misaligned incentives can at once harm consumers and undermine financial institutions. Indeed, as with subprime mortgages and securities backed by these mortgages, these products may at times also be connected to systemic risk.
At the same time, a determination of how to regulate financial practices both effectively and efficiently can be facilitated by the understanding of institutions' practices and systems that is gained through safety and soundness regulation and supervision. Similarly, risk assessment and compliance monitoring of consumer and prudential regulations are closely related, and thus entail both informational advantages and resource savings.
