Regulation W implements Federal Reserve Act sections 23A and 23B for covered transactions and other dealings between member banks and affiliates.
Regulation W is the Federal Reserve rule at 12 CFR Part 223 that implements sections 23A and 23B of the Federal Reserve Act. It limits and conditions transactions between a member bank and its affiliates so the bank is not used to transfer value to, or absorb excessive risk from, related companies.
Affiliates can include a company that controls the bank, a company under common control, certain investment funds advised by the bank or an affiliate, and specified financial subsidiaries. Subsidiaries of the bank are often treated differently, but definitions and exceptions must be checked.
Covered transactions include:
The attribution rule can treat a transaction with a third party as an affiliate transaction to the extent proceeds are used for the benefit of, or transferred to, an affiliate.
Section 23A generally applies two limits to covered transactions:
| Exposure | General limit |
|---|---|
| One affiliate | 10% of member bank capital stock and surplus |
| All affiliates combined | 20% of member bank capital stock and surplus |
Both tests apply after using Regulation W’s valuation, timing, and aggregation rules. The limits do not mean every affiliate transaction below 10% is permissible; collateral, market terms, low-quality-asset, safety-and-soundness, and other restrictions can still apply.
Credit transactions with affiliates generally require collateral with market value of at least:
| Collateral | Required coverage |
|---|---|
| U.S. government or agency obligations, qualifying guarantees, specified eligible paper, or segregated earmarked bank deposit | 100% |
| State or political-subdivision obligations | 110% |
| Other debt instruments, including loans and receivables | 120% |
| Stock, leases, or other real or personal property | 130% |
Coverage must be maintained while the transaction remains outstanding. Affiliate-issued securities and low-quality assets are among the ineligible collateral categories.
Assume a member bank has USD 500 million of capital stock and surplus. It already has USD 20 million of covered transactions with Affiliate A and proposes a new USD 40 million loan to that affiliate.
USD 500 million x 10% = USD 50 million.USD 20 million + USD 40 million = USD 60 million.Absent an applicable exemption or other rule treatment, USD 60 million exceeds the USD 50 million single-affiliate limit. Board approval or favorable pricing would not by itself cure that excess.
If the proposed loan were otherwise permitted and secured only by eligible corporate debt, 120% collateral coverage would generally require USD 40 million x 120% = USD 48 million of qualifying market value at the time of the transaction, with required coverage maintained afterward.
Section 23B generally requires covered transactions and specified other dealings to occur on terms and circumstances, including credit standards, that are substantially the same as or at least as favorable to the bank as comparable transactions with nonaffiliates. If no comparable transaction exists, the terms must be those the bank would in good faith offer to a nonaffiliate.
The requirement can apply to services, asset sales, agency arrangements, and other transactions beyond loans. “Arm’s length” is useful shorthand, but the bank needs evidence supporting valuation, pricing, credit standards, and other terms.
