In banking and finance, a covered transaction is any deal or activity that a specific federal rule singles out for mandatory reporting, restriction, or review. The label travels across at least five different regimes, and each one defines it on its own terms. A transaction that is “covered” for anti-money laundering purposes has nothing to do with one that is “covered” for national security review or for bank affiliate limits. The common thread is only the consequence: once your transaction fits the definition in a given statute, the obligations attach, and the penalties for ignoring them are steep.
Five regimes account for almost every use of the term you are likely to encounter:
- Section 23A of the Federal Reserve Act, limiting a bank’s exposure to its affiliates.
- The Bank Secrecy Act, requiring reports on large cash and suspicious transactions.
- FinCEN’s residential real estate rule, requiring reports on certain non-financed home transfers.
- The Volcker Rule, restricting proprietary trading and covered fund activity by banks.
- CFIUS regulations, subjecting certain foreign investments to national security review.
A sixth use appears in securities industry conflict-of-interest rules, most notably MSRB Rule G-23. Which definition applies to you depends on who you are and what you are doing.
Bank Affiliate Transactions Under Section 23A
Section 23A of the Federal Reserve Act gives the phrase its most precise statutory definition. The rule limits how much financial exposure a federally insured bank can have to entities in its own corporate family, so that insured deposits do not end up propping up a struggling parent or sibling.
Under Section 23A, a covered transaction between a bank and any single affiliate cannot exceed 10 percent of the bank’s capital stock and surplus, and covered transactions with all affiliates combined cannot exceed 20 percent. The statute defines “covered transaction” to include loans and credit extensions to an affiliate, purchases of securities issued by an affiliate, purchases of assets from an affiliate, accepting affiliate-issued securities as collateral for loans, issuing guarantees or letters of credit on an affiliate’s behalf, and derivative transactions that create credit exposure to the affiliate.1Office of the Law Revision Counsel. 12 U.S. Code 371c – Banking Affiliates
The limits apply to every insured depository institution that is a member of the Federal Reserve System, along with its subsidiaries. Any credit transaction with an affiliate must also be secured by qualifying collateral.
Covered Transactions Under the Bank Secrecy Act
The Bank Secrecy Act and its implementing regulations create two distinct categories of covered transactions. One is triggered by dollar amount, the other by suspicion.
Currency Transaction Reports
Any deposit, withdrawal, currency exchange, or other payment or transfer involving more than $10,000 in cash during a single business day requires a Currency Transaction Report filed with the Financial Crimes Enforcement Network.2eCFR. 31 CFR 1010.311 – Filing Obligations for Reports of Transactions in Currency The threshold applies to the total of all cash transactions by the same person at the same institution during the day, not to a single transaction in isolation. Three cash deposits of $4,000 at the same bank on the same day still generate a report.3U.S. Government Accountability Office. Currency Transaction Reports: Improvements Could Reduce Filer Burden While Still Providing Useful Information to Law Enforcement
The report is filed electronically through FinCEN’s BSA E-Filing System on Form 112.4Financial Crimes Enforcement Network. Bank Secrecy Act Filing Information Banks, credit unions, and other regulated financial institutions carry the obligation. Only physical currency counts. Checks, wire transfers, and electronic payments do not.
Suspicious Activity Reports
A Suspicious Activity Report is filed when a financial institution knows or has reason to suspect that a transaction involves potential criminal activity, whether or not it crosses the CTR threshold. For banks, transactions aggregating $5,000 or more require a SAR when a suspect is identified. When no suspect is identified, the threshold rises to $25,000.5Federal Financial Institutions Examination Council. Suspicious Activity Reporting – Overview
The most common SAR trigger is suspicion of structuring, meaning deliberately breaking up cash transactions to keep each below the $10,000 CTR line. Structuring is itself a federal crime, even when the underlying money is entirely legitimate.6Office of the Law Revision Counsel. 31 U.S. Code 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited A person who deposits $9,500 in cash on Monday and $9,500 on Tuesday to stay under the reporting line has committed a federal offense regardless of the source of the funds. Financial institutions must also file when a transaction has no apparent lawful purpose or is inconsistent with a customer’s known profile.
One detail catches people off guard. The institution is legally prohibited from telling the customer that a SAR has been filed. The gag rule extends to current and former employees of both the institution and any government agency that receives the report.7Office of the Law Revision Counsel. 31 U.S. Code 5318 – Compliance, Exemptions, and Summons Authority
Residential Real Estate Transfers
FinCEN has extended the covered transaction concept to residential real estate through a rule that took effect on March 1, 2026. Certain professionals involved in closings must report specific non-financed transfers of residential property to FinCEN, closing a gap that had let all-cash shell company purchases sidestep the scrutiny that applies to mortgage-financed deals.8Financial Crimes Enforcement Network. Residential Real Estate Reporting Requirement Fact Sheet
Reporting is required only when all three conditions are met: the property is residential, the transfer involves no bank financing, and the transferee is a legal entity such as an LLC or a trust. Transfers to individual homebuyers, mortgage-financed purchases, and transfers arising from death, divorce, or bankruptcy are excluded.8Financial Crimes Enforcement Network. Residential Real Estate Reporting Requirement Fact Sheet
The filing responsibility falls on the real estate professional closest to the closing, typically a settlement agent, title insurance agent, escrow agent, or attorney. A cascading priority list resolves cases where multiple professionals are involved. Only one person files per transfer, and the homebuyer has no filing obligation.9Financial Crimes Enforcement Network. Fact Sheet: FinCEN Issues Final Rule to Increase Transparency in Residential Real Estate Transfers
Separately, FinCEN’s Geographic Targeting Orders require title insurance companies in specified metropolitan areas to identify the natural persons behind shell companies used in non-financed residential purchases. Purchase-price thresholds are generally $300,000, though some areas use lower figures.10FinCEN.gov. FinCEN Renews Residential Real Estate Geographic Targeting Orders
Covered Transactions Under the Volcker Rule
The Volcker Rule works differently from the reporting regimes. It flatly prohibits certain activities by banking entities rather than requiring paperwork. A covered transaction under this rule is either proprietary trading or an investment in a covered fund.
Proprietary Trading
Proprietary trading is a banking entity using its own capital to buy and sell financial instruments for short-term profit rather than on behalf of customers. A transaction counts when it is booked to an account used for short-term resale, market-making, or similar purposes. The rule carves out exceptions for underwriting, market-making, and hedging, each with its own compliance requirements. Volcker applies to any “banking entity,” which includes insured depository institutions, their holding companies, and affiliates worldwide.
Covered Fund Investments
A covered fund is generally an investment vehicle that would qualify as an investment company under the Investment Company Act of 1940 but relies on certain exemptions to avoid registration. That category captures most hedge funds and private equity funds.11eCFR. 17 CFR 255.10 – Prohibition on Acquiring or Retaining an Ownership Interest in and Having Certain Relationships With a Covered Fund
A banking entity generally cannot invest its own capital in a covered fund or sponsor one. A narrow exception permits a banking entity to hold up to 3 percent of a single covered fund’s outstanding ownership interests, with total investments across all covered funds capped at 3 percent of the banking entity’s Tier 1 capital.12eCFR. 17 CFR 75.12 – Permitted Investment in a Covered Fund
The Volcker Rule also imports Section 23A. When a banking entity sponsors or advises a covered fund, the fund is treated as an affiliate, so loans, asset purchases, guarantees, and other credit extensions between the bank and the fund count against the 10 percent single-affiliate cap and must be collateralized.
CFIUS National Security Covered Transactions
The Committee on Foreign Investment in the United States uses “covered transaction” to describe deals that can trigger a national security review. If a transaction qualifies, CFIUS can investigate it, attach conditions, or block it, and in some cases order it unwound after closing.
Under the CFIUS regulations, a covered transaction includes any transaction through which a foreign person acquires control of a U.S. business, makes a covered investment that grants certain rights (such as access to material nonpublic technical information, board membership, or involvement in substantive decision-making), or any arrangement structured to evade review.13eCFR. 31 CFR 800.213 – Covered Transaction
Mandatory Filings for TID Businesses
Most CFIUS filings are voluntary. Certain transactions involving what the regulations call “TID U.S. businesses” require a mandatory declaration filed at least 30 days before the transaction closes.14eCFR. 31 CFR 800.401 – Mandatory Declarations A TID U.S. business produces or develops critical technologies, performs specified functions related to critical infrastructure, or collects sensitive personal data on U.S. citizens.15eCFR. 31 CFR 800.248 – TID U.S. Business The mandatory filing applies when a foreign government has a substantial interest in the acquirer, or when the target handles critical technologies that would require export authorization.
Covered Real Estate
A separate set of CFIUS regulations covers purchases or leases by foreign persons near sensitive locations such as military installations, major airports, and strategic seaports. These transactions can trigger review even when no U.S. business is being acquired. The relevant installations and ports are listed in appendices to the regulations, and the covered areas extend to property in the vicinity.16U.S. Department of the Treasury. CFIUS Real Estate Instructions (Part 802)
Securities and Municipal Advisory Rules
In the securities industry, “covered transaction” appears most prominently in rules preventing conflicts when a firm plays two roles. MSRB Rule G-23 is the clearest example. It addresses the problem of a dealer that advises a municipality on structuring a bond issue and then underwrites the same issue for its own profit.
Under the current rule, a dealer that has served as financial advisor to an issuer is prohibited from underwriting or placing that same issue of municipal securities.17Municipal Securities Rulemaking Board. MSRB Notice 2019-13 – Request for Comment on MSRB Rule G-23 on Activities of Dealers Acting as Financial Advisors The prohibition keeps the dealer’s structuring advice from being shaped by the profit it could earn as underwriter.18Municipal Securities Rulemaking Board. MSRB Proposes Prohibition on Dealers Acting as Financial Advisor and Underwriter on New Issue of Municipal Securities
More broadly, the SEC and FINRA classify certain affiliated-party dealings as covered transactions requiring heightened disclosure or due diligence. When a broker-dealer executes a transaction with its own affiliate or a related party, the customer must be told of the relationship and the potential conflict.
Penalties Across the Regimes
The consequences of mishandling a covered transaction depend on which framework applies, and they are uniformly serious.
Under the BSA, a willful failure to file a required CTR or SAR carries a civil penalty of up to the greater of $25,000 or the amount involved, capped at $100,000.19Office of the Law Revision Counsel. 31 U.S. Code 5321 – Civil Penalties Criminal penalties for willful violations reach $250,000 in fines and five years in prison, doubling when the violation occurs alongside another crime or is part of a pattern involving more than $100,000 over 12 months.20U.S. Government Publishing Office. 31 U.S. Code 5322 – Criminal Penalties Structuring is prosecuted aggressively, and the government routinely seeks civil forfeiture of the funds involved, so the money can be lost entirely even when its source was lawful.
The Volcker Rule is enforced by multiple federal agencies depending on the banking entity involved. Violations can bring cease-and-desist orders, mandatory divestiture of prohibited investments, and civil money penalties. A banking entity that holds a prohibited interest in a covered fund can be ordered to sell it.
Skipping a mandatory CFIUS filing carries a civil penalty of up to $5,000,000 or the transaction’s value, whichever is greater.21eCFR. 31 CFR Part 800 Subpart I – Penalties and Damages CFIUS can also order the parties to unwind a completed transaction that was never submitted for review.
In the securities context, a municipal advisor or broker-dealer that violates covered transaction rules faces regulatory censure, fines, and potential revocation of registration. A dealer that underwrites an issue it also advised on, in violation of Rule G-23, may face disciplinary action from FINRA or the SEC. Individuals can be suspended; firms face monetary fines and disgorgement of profits from the conflicted deal.
