A covered transaction is a deal or activity that meets the specific definition in a federal statute or regulation and therefore triggers a mandatory obligation — a report to file, a disclosure to make, a limit to observe, or a prohibition to respect. The phrase has no single meaning across banking and finance. What counts as a covered transaction under anti-money laundering rules has nothing in common with what counts under national security review or bank-affiliate limits, and the only reliable way to know your obligation is to identify which regime applies to your situation.
Five federal frameworks use the term in materially different ways. Each is worth understanding on its own terms.
Bank-Affiliate Transactions Under Section 23A
Section 23A of the Federal Reserve Act uses “covered transaction” to describe dealings between a federally insured bank and any entity in its own corporate family — parent, sister subsidiary, or other affiliate. The purpose is to keep insured deposits from being funneled into a struggling affiliate.
The statute defines a covered transaction to include loans and credit extensions to an affiliate, purchases of securities issued by an affiliate, purchases of assets from an affiliate, acceptance of affiliate-issued securities as collateral, guarantees or letters of credit issued 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
Two hard caps apply. Covered transactions with 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. Credit transactions with an affiliate also have to be secured by qualifying collateral. The limits apply to every insured depository institution that is a member of the Federal Reserve System, plus its subsidiaries.
Covered Transactions Under Anti-Money Laundering Rules
The Bank Secrecy Act creates two separate categories of covered transactions, each tied to a different filing.
Currency Transactions Over $10,000
Any deposit, withdrawal, currency exchange, or other payment involving more than $10,000 in cash during a single business day triggers 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 looks at the total of all cash transactions by the same person at the same institution during the day, so three cash deposits of $4,000 at one bank in one day still require a report.3U.S. Government Accountability Office. Currency Transaction Reports: Improvements Could Reduce Filer Burden While Still Providing Useful Information to Law Enforcement
Reports are filed electronically on FinCEN Form 112.4Financial Crimes Enforcement Network. Bank Secrecy Act Filing Information The requirement covers only physical currency. Checks, wires, and electronic payments do not count.
Suspicious Activity, Regardless of Amount
A Suspicious Activity Report is filed when a financial institution knows or has reason to suspect a transaction involves potential criminal activity. For banks, transactions aggregating $5,000 or more require a SAR when a suspect is identified. The threshold is $25,000 when no suspect is identified.5Federal Financial Institutions Examination Council. Suspicious Activity Reporting – Overview
The most common trigger is suspected structuring — deliberately breaking cash transactions into pieces below $10,000 to avoid a CTR. Structuring is a federal crime on its own, even when the underlying money is legitimate.6Office of the Law Revision Counsel. 31 U.S. Code 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited Depositing $9,500 in cash on Monday and another $9,500 on Tuesday to stay below the reporting line is prosecutable regardless of the money’s source.
Institutions are also required to weigh whether a transaction has no apparent lawful purpose or is inconsistent with the customer’s known profile. And one detail routinely surprises customers: the institution is legally prohibited from telling you a SAR has been filed. The prohibition extends to current and former employees of the institution and of 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 to Entities
FinCEN extended covered-transaction reporting to residential real estate through a rule effective March 1, 2026. It closes a gap that let buyers using shell companies and all-cash purchases avoid the anti-money laundering scrutiny that comes with mortgage financing.8Financial Crimes Enforcement Network. Residential Real Estate Reporting Requirement Fact Sheet
Reporting is required only when every one of these applies: the property is residential real estate, no bank financing is involved (an all-cash purchase or gift, for example), and the property is transferred to a legal entity such as an LLC or to a trust. Transfers to individual buyers, 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 falls on a real estate professional at the closing, typically a settlement agent, title insurance agent, escrow agent, or attorney, with a cascading priority list identifying which one is responsible when multiple parties are involved. Only one person files per transfer. The homebuyer has no filing obligation.9Financial Crimes Enforcement Network. Fact Sheet: FinCEN Issues Final Rule to Increase Transparency in Residential Real Estate Transfers
Covered Transactions Under the Volcker Rule
The Volcker Rule works differently from the reporting regimes. Instead of triggering a filing, a covered transaction under this rule is prohibited outright, with narrow exceptions. Two categories are involved.
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 as proprietary trading when it is booked to an account used for short-term resale, market-making, or similar purposes. The rule carves out underwriting, market-making, and hedging, but each carve-out carries its own compliance conditions. A trading desk relying on the market-making exception, for instance, has to show its inventory is designed to meet reasonably expected near-term customer demand rather than to place a directional bet.
The rule reaches any “banking entity,” including 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.10eCFR. 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 ownership of up to 3 percent of a single covered fund’s outstanding interests, with total covered-fund investments capped at 3 percent of the banking entity’s Tier 1 capital.11eCFR. 17 CFR 75.12 – Permitted Investment in a Covered Fund
The Volcker Rule also imports the Section 23A affiliate limits. When a banking entity sponsors or advises a covered fund, the fund is treated as an affiliate, so any loan, asset purchase, or guarantee between the bank and the fund counts against the 10 percent single-affiliate cap and needs qualifying collateral.
CFIUS Covered Transactions
The Committee on Foreign Investment in the United States uses “covered transaction” to identify deals subject to national security review. When a transaction qualifies, CFIUS can investigate, impose conditions, or block the deal, and it can act even after closing.
A covered transaction includes any transaction through which a foreign person acquires control of a U.S. business, any covered investment that grants specific rights such as access to material nonpublic technical information, board membership, or involvement in substantive decision-making, and any arrangement structured to evade review.12eCFR. 31 CFR 800.213 – Covered Transaction
When Filing Is Mandatory
Most CFIUS filings are voluntary. Certain deals involving “TID U.S. businesses” require a mandatory declaration at least 30 days before closing.13eCFR. 31 CFR 800.401 – Mandatory Declarations A TID U.S. business is one that produces or develops critical technologies, performs specified functions related to critical infrastructure, or collects sensitive personal data on U.S. citizens.14eCFR. 31 CFR 800.248 – TID U.S. Business Mandatory filing applies when a foreign government has a substantial interest in the acquirer, or when the target’s critical technologies would require export authorization.
Real Estate Near Sensitive Sites
A separate CFIUS regime covers purchases or leases of real estate by foreign persons near sensitive locations, including military installations, major airports, and strategic seaports. These transactions can trigger review even when no U.S. business is being acquired. The specific installations and ports are listed in appendices to the regulations, and the covered areas extend to nearby property.15U.S. Department of the Treasury. CFIUS Real Estate Instructions (Part 802)
Municipal Advisor and Broker-Dealer Covered Transactions
In the securities industry, “covered transaction” comes up most often in conflict-of-interest rules for firms that play more than one role in a deal. The clearest case is MSRB Rule G-23, which governs municipal securities dealers that also advise the issuers of those securities.
The rule targets role switching: a dealer advises a municipality on structuring a bond issue, then underwrites the same issue for profit. The MSRB concluded that disclosure alone could not cure the conflict. Under the current rule, a dealer that has served as financial advisor to an issuer is prohibited from underwriting or placing that same issue.16Municipal Securities Rulemaking Board. MSRB Notice 2019-13 – Request for Comment on MSRB Rule G-23 on Activities of Dealers Acting as Financial Advisors17Municipal Securities Rulemaking Board. MSRB Proposes Prohibition on Dealers Acting as Financial Advisor and Underwriter on New Issue of Municipal Securities
More broadly, SEC and FINRA rules treat certain affiliated-party dealings as covered transactions requiring heightened disclosure or due diligence. When a broker-dealer transacts with its own affiliate or a related party, the customer must be told about the relationship and the potential conflict.
What Missing a Covered Transaction Obligation Costs
Penalties vary by regime, but each is serious enough that treating the definitions as optional is not viable.
BSA and Anti-Money Laundering
Willfully failing 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 $100,000.18Office of the Law Revision Counsel. 31 U.S. Code 5321 – Civil Penalties Criminal penalties for willful BSA violations reach $250,000 in fines and five years in prison. When the violation occurs alongside another crime or is part of a pattern involving more than $100,000 over 12 months, the maximum fine doubles to $500,000 and the prison term extends to ten years.19U.S. Government Publishing Office. 31 U.S. Code 5322 – Criminal Penalties Structuring cases also routinely include civil forfeiture, which can take the money even when it was earned legally.
Volcker Rule
Enforcement is shared among federal banking agencies. Consequences include cease-and-desist orders, mandatory divestiture of prohibited investments, and civil money penalties. Inadequate compliance programs can draw enforcement of their own.
CFIUS
Skipping a mandatory filing carries a civil penalty of up to $5,000,000 or the value of the transaction, whichever is greater.20eCFR. 31 CFR Part 800 Subpart I – Penalties and Damages CFIUS can also order the parties to unwind a completed deal, a remedy that has been used against foreign acquisitions of U.S. technology companies.
Securities
A municipal advisor or broker-dealer that breaches covered-transaction rules faces regulatory censure, fines, and potential loss of registration. A dealer that underwrites an issue it also advised on, in violation of Rule G-23, can face disciplinary action from FINRA or the SEC. Individuals risk license suspension; firms face monetary penalties and disgorgement of profits from the conflicted transaction.
