Regulation W (Reg W) limits the risks to banks from their affiliates by imposing strict rules on financial transactions between member banks and affiliated entities.

Whether you are a banking compliance officer, a finance student, or a curious consumer, understanding which entity Reg W restricts—and how—is essential for grasping how the U.banking system safeguards itself against contagion and abuse It's one of those things that adds up..
What Is Regulation W?
Regulation W is a federal regulation that governs transactions between a member bank and its affiliates. Now, its primary purpose is to prevent a bank from using its resources—such as deposits, which are often insured by the Federal Deposit Insurance Corporation (FDIC)—to support risky or poorly managed affiliated companies. By restricting the amount and nature of credit a bank can extend to an affiliate, Reg W reduces the likelihood that problems at an affiliate will spill over and threaten the safety and soundness of the bank itself.
The regulation applies to national banks, state-chartered banks that are members of the Federal Reserve System, and certain other depository institutions. While nonmember banks are not directly subject to Regulation W, they are generally covered by similar rules enforced by their primary federal regulators, ensuring that the broader banking system operates under consistent affiliate transaction standards.

- Other subsidiaries of the bank itself
- Entities under common control with the bank through a parent company
Take this: if a bank is owned by a holding company that also operates an investment firm, an insurance provider, and a mortgage lending subsidiary, each of those companies is considered an affiliate. Practically speaking, reg W treats transactions with these entities differently than transactions with unrelated third parties because of the inherent risk of self-dealing. A bank might be tempted to extend favorable loan terms to an affiliate to prop up its balance sheet, even if the affiliate’s creditworthiness does not justify such terms. Reg W exists to prevent exactly that scenario Easy to understand, harder to ignore..
