Overview
Regulation U (commonly called “Reg U”) is a Federal Reserve Board regulation that limits the amount of credit institutions may extend when loans are secured by securities for the purpose of buying additional securities. Its primary goal is to restrict leverage in securities financing so that borrowers and lenders are less exposed to deep losses when markets move against leveraged positions.
Key points at a glance
– Reg U applies to loans by entities other than broker‑dealers (for broker‑dealers, Regulation T is the primary rule).
– When a loan is secured by marketable securities and the loan proceeds are used to buy more securities, the maximum initial loan value is generally 50% of the market value of the collateral.
– For loans over $100,000 that are subject to Reg U, lenders must obtain a purpose statement (Form U‑1) describing the intended use of proceeds.
– Some loans and lenders are treated differently or are exempt (for example, certain nonbank lenders and some employee stock plan loans).

How Regulation U works — mechanics and requirements
1. Scope: Reg U covers credit extended by banks, savings institutions, credit unions, insurance companies and other non‑broker/dealer lenders when:
• The loan is secured by securities (stocks, many mutual funds and other market‑traded securities), and
• The loan proceeds are intended to be used to purchase or carry additional margin stock (i.e., to buy securities).
2. Purpose statement: If a loan is for more than $100,000 and secured by securities, the lender must obtain a signed Form U‑1 (or equivalent documentation) stating the purpose of the loan—specifically whether the proceeds will be used to purchase or carry margin securities. This helps the lender and regulators determine whether Reg U limits apply.
3. Loan‑to‑value limit: For loans subject to Reg U where proceeds are used to buy or carry margin stocks, the initial maximum loan amount is 50% of the market value of the securities held as collateral (i.e., a 50% loan-to-value). Lenders can set lower LTVs at their discretion.
4. Collateral valuation: Market value should reflect prevailing market prices for the securities used as collateral. Lenders must revalue collateral according to their internal policies and regulatory standards (margin maintenance and subsequent adjustments are handled under other rules or agreements).
5. Exemptions and special cases:
• Loans by broker‑dealers are governed by Regulation T rather than Reg U.
• Some nonbank lenders are subject to different supervisory frameworks, and certain employee stock plan loans may be treated differently or exempt.
• Loans secured by securities but not intended for purchasing or carrying margin stocks are not subject to the Reg U 50% restriction, although other lending and safety rules still apply.
Example calculations
– Collateral worth $400,000; loan purpose is buying securities → max loan = 50% × $400,000 = $200,000.
– Collateral worth $500,000; loan purpose is buying securities → max loan = 50% × $500,000 = $250,000.
Practical steps for bank lenders to comply with Regulation U
1. Policy and training:
• Maintain a written Reg U compliance policy that defines when Reg U applies, who must sign Form U‑1, valuation rules, and monitoring processes.
• Train lending, credit review, and front‑line staff on identification of loans subject to Reg U and on completion/retention of Form U‑1.
2. Intake and documentation:
• Screen all loan applications secured by securities to determine loan purpose; for loans > $100,000, obtain a signed purpose statement (Form U‑1).
• Document collateral descriptions, valuation methods (market prices, date and source), and the computation of the allowable loan amount under Reg U.
3. Credit decision and limits:
• Enforce the 50% initial LTV limit for loans intended to buy securities; impose stricter limits if the institution’s risk appetite requires.
• For loans not intended to buy securities, document why Reg U does not apply.
4. Monitoring and margin maintenance:
• Re‑value collateral periodically and maintain margin maintenance procedures to identify when additional collateral is required or loans must be called/reduced.
• Ensure credit files retain evidence of ongoing compliance and any remedial actions taken.
5. Audit and regulatory readiness:
• Include Reg U coverage in internal/external audits and maintain records (including Form U‑1) for the retention period required by regulators.
• Correct any material noncompliance promptly and notify regulators if required.
Practical steps for borrowers (individuals or businesses) seeking loans secured by securities
1. Know the loan purpose and consequences:
• If you ask a bank for a loan secured by securities and plan to use proceeds to buy more securities, expect the lender to treat that loan under Reg U and limit your initial loan proceeds to 50% of the collateral’s market value.
2. Prepare documentation:
• Be ready to sign a Form U‑1 or similar purpose statement for loans above $100,000. Provide clear information about how you will use the funds.
3. Understand collateral valuation and LTV:
• Realize that the lender will value your securities at current market prices and apply the 50% limit. If you want more borrowing capacity, you must provide additional eligible collateral not intended for the purchase of more securities.
4. Alternative financing:
• If Reg U limits are constraining and you need higher leverage for securities purchases, consider borrowing from a broker‑dealer under Regulation T (margin accounts), or use other financing sources—each comes with different rules and risks.
Recordkeeping, monitoring, and common compliance pitfalls
– Failure to obtain or retain a proper purpose statement (Form U‑1) for loans >$100,000 is a common compliance gap.
– Misclassifying the loan purpose (e.g., treating the loan as for business operations when it is intended to buy securities) can lead to regulatory violation.
– Using illiquid or hard‑to‑value securities as collateral without appropriate haircuts or valuation procedures increases risk.
– Inadequate monitoring of collateral values can leave a firm exposed after market declines.
Enforcement and consequences
Regulatory enforcement can include examination findings, required corrective actions, fines, and other supervisory measures. Institutions are expected to maintain documentation proving compliance and to act promptly to remedy deficiencies.
History and relationship to other rules
– Reg U was promulgated by the Federal Reserve to regulate credit by banks and other non‑broker/dealer lenders where the credit is secured by margin stocks and used to buy or carry margin stocks. (Regulation T covers broker‑dealer margin credit.)
– The rules evolved in the 1930s and thereafter as part of broader efforts to control systemic risk from excessive securities leverage.
