SERIES 7 PREP | FINANCIAL REGULATION COURSES
Regulation W — codified at 12 CFR Part 223 and effective April 1, 2003 — is the Federal Reserve Board regulation implementing Sections 23A and 23B of the Federal Reserve Act, which establish quantitative limits, collateral requirements, and market terms standards for transactions between a member bank and its affiliates. Issued under the authority of Sections 23A(f) and 23B(e) of the Federal Reserve Act at 12 U.S.C. 371c and 371c-1, and subsequently amended by Sections 608 and 609 of the Dodd-Frank Wall Street Reform and Consumer Protection Act effective July 21, 2012, Regulation W serves as the primary prudential safeguard preventing banks from using their access to federally insured deposits and the Federal Reserve's discount window — the government-backed safety net — to subsidise or prop up non-bank affiliates, thereby concentrating the financial system's risks inside the insured depository institution where they are ultimately backstopped by the taxpayer.
The Policy Rationale — Protecting the Federal Safety Net
The conceptual foundation of Regulation W is straightforward and directly stated in the Federal Reserve's own regulatory framework. Banks occupy a privileged position in the financial system — they have access to federally insured deposits that cost less to obtain than uninsured market funding, and they can borrow from the Federal Reserve's discount window in times of stress at below-market rates. These privileges — the federal safety net — exist to ensure the stability of the payments system and to protect depositors. They were not created to be used as a funding subsidy for the securities affiliates, insurance affiliates, real estate subsidiaries, and other non-bank entities that may be part of the same financial holding company structure.
Without restrictions on affiliate transactions, a bank could channel cheap federally subsidised funding to its affiliates in the form of loans, asset purchases, or guarantees — effectively transferring the safety net subsidy to non-bank entities that have no independent entitlement to it. In the event those affiliates suffer losses, the problems would flow back to the bank and ultimately to the deposit insurance fund and the Federal Reserve's emergency lending facilities. Sections 23A and 23B were enacted to prevent this subsidy transfer and to maintain a genuine firewall between the insured bank and its non-bank affiliates.
The Scope — Member Banks and Their Affiliates
Regulation W applies to member banks — national banks and state-chartered banks that are members of the Federal Reserve System. The Federal Deposit Insurance Act at 12 U.S.C. 1828(j) extends the requirements of Sections 23A and 23B to insured state non-member banks in the same manner as if they were member banks, effectively making the affiliate transaction restrictions applicable to virtually all federally insured depository institutions. The Home Owners' Loan Act extends the same restrictions to insured savings associations.
An affiliate is defined broadly in Section 223.2 of Regulation W to include any company that controls the member bank, any company under common control with the member bank, any company whose securities are held primarily for the benefit of the bank or its affiliates, and any investment fund advised by the bank or one of its affiliates. Companies that the member bank itself controls are generally not its affiliates — Section 223.2(b) excludes the bank's own subsidiaries from the definition unless the subsidiary is a depository institution or a financial subsidiary, is directly controlled by an affiliate of the bank other than a depository institution or by the shareholders who control the bank, is an employee stock option plan or similar trust for the benefit of the shareholders, partners, members or employees of the bank or its affiliates, or has been determined to be an affiliate by the Board or the bank's appropriate federal banking agency. The breadth of the affiliate definition is deliberately expansive — Congress and the Federal Reserve have consistently interpreted affiliation relationships broadly to prevent circumvention through complex corporate structures designed to place risk-taking entities just outside the technical definition of affiliate.
Covered Transactions — What Regulation W Restricts
Regulation W applies only to covered transactions — a defined category of transactions between a member bank and its affiliates that pose the most significant risks of subsidy transfer and potential harm to the bank. Section 23A of the Federal Reserve Act and Section 223.3 of Regulation W define covered transactions to include six categories.
Loans and extensions of credit to an affiliate — any loan, advance, line of credit, or other extension of credit made by the member bank to an affiliate — are the most obvious form of affiliate funding and the primary target of the original Section 23A restrictions.
Purchases of assets from an affiliate — any purchase of securities, loans, real estate, or other assets from an affiliate — allow the affiliate to transfer assets of questionable quality to the bank in exchange for cash, potentially stripping value from the bank to benefit the affiliate.
Purchases of assets subject to an agreement to repurchase — repo transactions in which the affiliate sells assets to the bank and agrees to repurchase them — are economically equivalent to loans secured by the sold assets and are treated as covered transactions accordingly.
Acceptance of securities issued by an affiliate as collateral for a loan — using an affiliate's own securities as collateral for a bank loan — is a form of circular credit support that could allow an affiliate to borrow against inflated valuations of its own equity or debt instruments.
Issuance of a guarantee, acceptance, or letter of credit on behalf of an affiliate — having the bank backstop the obligations of its affiliate — transfers the bank's creditworthiness and its safety net access to the affiliate without a direct cash disbursement. The Federal Reserve has treated guarantees as particularly concerning because their full economic exposure may not appear on the bank's balance sheet during normal operations.
Transactions that involve the bank investing in securities issued by an affiliate — certain investments in affiliate securities — are also covered when they create credit exposure to the affiliate.
The Quantitative Limits — Ten Percent and Twenty Percent
Section 23A establishes two quantitative limits on covered transactions that are among the most examination-relevant specific numbers in Regulation W.
The ten percent limit restricts the aggregate amount of covered transactions between a member bank and any single affiliate to no more than ten percent of the member bank's capital stock and surplus. Capital stock and surplus for this purpose equals the sum of the bank's Tier 1 and Tier 2 capital under applicable risk-based capital guidelines. A bank with one billion dollars of capital stock and surplus may have no more than one hundred million dollars in aggregate covered transactions with any single affiliate.
The twenty percent aggregate limit restricts the total amount of all covered transactions between a member bank and all of its affiliates combined to no more than twenty percent of the member bank's capital stock and surplus. The aggregate limit applies across all affiliates collectively — if a bank has five affiliates each at the ten percent individual limit, the twenty percent aggregate limit is binding before any of the individual limits are reached.
These limits apply to the outstanding aggregate amount of covered transactions at any point in time — not to the amount of new transactions entered in a period. A bank must monitor its covered transaction exposures continuously to ensure neither limit is breached.
The Collateral Requirements
Section 23A imposes collateral requirements on certain covered transactions — primarily loans and extensions of credit to affiliates — to ensure that the bank retains security interests sufficient to recover the loaned amount if the affiliate defaults. The required collateral coverage depends on the type of collateral pledged.
Covered transactions secured by United States Treasury securities or obligations of a federal agency require collateral with a market value of at least one hundred percent of the outstanding covered transaction amount. Covered transactions secured by obligations of states or political subdivisions require one hundred and ten percent coverage. Covered transactions secured by other debt instruments require one hundred and twenty percent coverage. Covered transactions secured by equity securities require one hundred and thirty percent coverage. Low-quality assets — assets that are classified as substandard, doubtful, or loss under bank examination standards — have no collateral value under Regulation W and may not be used to satisfy the collateral requirements.
These tiered collateral requirements reflect the relative liquidity and credit quality of different collateral types — the less liquid or more credit-risky the collateral, the greater the margin required above the loan amount to protect the bank against collateral value deterioration.
Exempt Transactions — Relief from the Limits, Not from Sound Banking
Section 23A(d) and Sections 223.41 and 223.42 of Regulation W exempt certain covered transactions from the quantitative limits and the collateral requirements, but every exempt transaction with an affiliate must still be on terms consistent with safe and sound banking practices. The most significant exemption concerns depository institutions under eighty percent common control — where the member bank controls eighty percent or more of the voting securities of the other institution, the other institution controls eighty percent or more of the member bank's, or one company controls eighty percent or more of both. These sister-bank transactions escape the limits and the collateral requirements, yet Congress deliberately left them subject to the separate prohibition on a member bank's purchase of a low-quality asset from an affiliate.
Section 23A also exempts credit to an affiliate fully secured by obligations of the United States or its agencies, obligations fully guaranteed by them, or a segregated, earmarked deposit account with the bank, and Regulation W extends the exemption to any credit transaction to the extent that it is and remains so secured. The exemption thus covers only the secured portion and moves with the collateral's value — in the regulation's own example, a one hundred dollar loan secured by Treasury securities worth fifty dollars and real estate worth seventy-five dollars is a covered transaction of fifty dollars, and if the Treasury securities fall to forty-five dollars the covered transaction rises to fifty-five dollars.
A third exemption turns on price: a member bank's purchase from an affiliate of an asset with a readily identifiable and publicly available market quotation, bought at or below its current market quotation, is exempt from the low-quality asset prohibition as well as from the limits and collateral rules. The asset qualifies only if its price is quoted routinely in a widely disseminated publication available to the general public — a test which, the Federal Reserve has explained, generally admits only exchange-traded assets, so that a qualifying asset has a true market quotation and examiners can verify the price paid.
Section 23B — The Market Terms Requirement
While Section 23A imposes quantitative limits on covered transactions, Section 23B of the Federal Reserve Act and Subpart F of Regulation W impose a market terms requirement — covered transactions and certain other transactions between a member bank and its affiliates must be conducted on terms and conditions that are at least as favourable to the bank as those prevailing at the time the transaction is entered into for comparable transactions with non-affiliated companies.
This arm's-length market terms standard prevents the bank from providing below-market funding to its affiliates — it must charge interest rates, fees, and prices that reflect genuine market rates rather than artificially subsidised terms that effectively transfer value from the bank to the affiliate. Section 23B applies to a broader range of transactions than Section 23A — including transactions that may not qualify as covered transactions but that could still involve non-market pricing between the bank and its affiliates.
Section 23B — Fiduciary Purchases, Affiliate Underwritings and Advertising
Alongside the market terms requirement, Section 23B of the Federal Reserve Act and Sections 223.53 and 223.54 of Regulation W impose three further restrictions. The first concerns the bank's fiduciary business — a member bank may not purchase as fiduciary any security or other asset from an affiliate unless the purchase is permitted under the instrument creating the fiduciary relationship, by court order, or by the law of the jurisdiction governing the fiduciary relationship.
The second applies while an affiliate is distributing securities. A member bank, whether acting as principal or as fiduciary, may not knowingly purchase or otherwise acquire, during the existence of any underwriting or selling syndicate, a security of which an affiliate is a principal underwriter — unless, before the security is initially offered for sale to the public, a majority of the bank's directors has approved the purchase on a determination that it is a sound investment for the bank, or for the person on whose behalf the bank acts as fiduciary, irrespective of the affiliate's role. The directors need not approve each purchase separately: they may instead approve standards for such acquisitions, provided each acquisition meets the standards and a majority of the directors periodically reviews both the acquisitions and the standards.
The third is the advertising restriction. A member bank and its affiliates may not publish any advertisement or enter into any agreement stating or suggesting that the bank will in any way be responsible for the obligations of its affiliates. Read literally, that language would bar the bank from guaranteeing an affiliate's obligations at all, so Regulation W reads it alongside Section 23A — it does not prohibit a guarantee, acceptance or letter of credit issued on behalf of an affiliate to the extent the transaction satisfies the quantitative limits and the collateral requirements, nor a reference to such an instrument where the law otherwise requires one.
The Dodd-Frank Amendments — Strengthening the Firewall
Sections 608 and 609 of the Dodd-Frank Wall Street Reform and Consumer Protection Act amended Sections 23A and 23B effective July 21, 2012, in several significant respects that reflected the lessons of the 2008 financial crisis.
The amendments extended the covered transaction definition to include credit exposure arising from derivative transactions and securities lending transactions between a member bank and its affiliates — two transaction types that had created substantial but largely unrecognised inter-affiliate exposures during the financial crisis and that the original Sections 23A and 23B did not specifically address. These off-balance-sheet exposures had enabled significant subsidy transfer to affiliates without appearing as conventional covered transactions subject to the ten and twenty percent limits. The amendments further required that each loan or extension of credit to an affiliate, each guarantee, acceptance or letter of credit issued on its behalf, and any credit exposure to it arising from a derivative or securities lending transaction be secured by the required collateral at all times, where Section 23A had previously required the collateral only at the time of the transaction, and they extended the affiliate definition to any investment fund for which the member bank or one of its affiliates is an investment adviser.
Examination and Enforcement
The Federal Reserve conducts examinations of member banks for Regulation W compliance as part of its ongoing supervisory programme. Examiners review covered transaction records, collateral documentation, market terms analyses for Section 23B transactions, and the bank's internal policies and procedures for monitoring and controlling affiliate transaction exposures.
Violations of Sections 23A and 23B and Regulation W can result in cease and desist orders issued by the Federal Reserve, civil money penalties, and requirements to unwind non-compliant transactions. The Federal Reserve may also require a bank to take corrective action to bring outstanding covered transactions within the applicable limits when a violation is discovered during examination.
Examination Relevance and Key Takeaways
Regulation W is tested on the Series 7 examination in the context of banking regulation, the Federal Reserve's supervisory framework, and the restrictions governing transactions between banks and their non-bank affiliates.
The key points to retain are these.
Regulation W — 12 CFR Part 223, effective April 1, 2003 — implements Sections 23A and 23B of the Federal Reserve Act at 12 U.S.C. 371c and 371c-1, governing transactions between member banks and their affiliates. Its purpose is preventing banks from using their access to federally insured deposits and the Federal Reserve safety net to subsidise non-bank affiliates within the same holding company structure. Regulation W applies to member banks and — through the Federal Deposit Insurance Act at 12 U.S.C. 1828(j) — to all insured depository institutions. Affiliates are defined broadly to include all companies under common control and investment funds advised by the bank or its affiliates.
Covered transactions under Section 23A include loans to affiliates, asset purchases from affiliates, repo transactions with affiliates, acceptance of affiliate securities as collateral, and guarantees or letters of credit on behalf of affiliates. Section 23A limits covered transactions with any single affiliate to ten percent of the bank's capital stock and surplus and limits aggregate covered transactions with all affiliates combined to twenty percent of capital stock and surplus. Collateral requirements range from one hundred percent for Treasury security collateral to one hundred and thirty percent for equity collateral. Section 23B requires all covered transactions and related transactions to be conducted on terms at least as favourable to the bank as those available for comparable non-affiliate transactions — the arm's-length market terms standard. The Dodd-Frank Act amendments effective July 21, 2012 extended covered transaction coverage to derivative and securities lending transactions with affiliates, closing gaps that had allowed substantial off-balance-sheet inter-affiliate exposures to develop outside the Section 23A quantitative limits during the 2008 financial crisis.
