SAR and CTR Data: Millions of Reports, Uneven Coverage

SAR reporting volume measures the suspicious activity reports financial institutions file, while AML enforcement depends on what investigators can do with the information. Currency transaction reports add a much larger stream of cash-transaction data. If your institution celebrates a rising filing count while whole payment channels escape review, that count misses the failure you can see.

What Is the Difference Between SAR and CTR?

A suspicious activity report describes activity that meets the institution’s reporting standard for suspicion. A currency transaction report records qualifying cash transactions, generally more than $10,000 by or on behalf of one person in a business day, including aggregated transactions. The first turns on suspicious activity. The second turns on cash activity and the reporting threshold.

The Financial Crimes Enforcement Network’s description of the reporting requirements includes bank transactions involving suspected illicit funds, attempts to evade reporting requirements, and activity without an apparent lawful purpose or reasonable explanation. The bank rule covers qualifying suspicious transactions totaling at least $5,000. Covered money services business activity generally has a $2,000 threshold, with a higher threshold for specified issuer reviews.

These reports give investigators information about transactions and people. Their usefulness begins with what the institution notices: a payment channel left outside monitoring can leave investigators without the information they need to follow the money.

How Many SAR Reports Are Filed Each Year?

The Financial Crimes Enforcement Network reported approximately 4.8 million SARs in fiscal 2025.

SAR Filing Volumes by Institution Type and AML Workload

SAR filing volumes by institution type show where AML reporting workload originates. Depository institutions supplied the largest category in every year of this FinCEN industry series, followed by money services businesses.

Depository institutions filed 839,314 SARs in calendar 2014 and 2,037,214 in calendar 2024. Money services businesses filed 706,163 and 1,161,768 in those same years.

CTR Volume Starts With a Different Trigger

The Financial Crimes Enforcement Network reported approximately 21.5 million CTRs in fiscal 2025. That larger volume reflects a reporting system built around cash transactions, without requiring the institution to decide that each transaction is suspicious.

The Government Accountability Office’s study of currency transaction reports supplies a detailed view of who files them. Across fiscal 2019 through fiscal 2023, it counted 90,403,652 CTRs. Depository institutions accounted for 77,789,487 of them, making banks central to the flow of cash-reporting information.

The study also identified inflation as a reason reporting volume can grow. The cash-reporting threshold stayed fixed while prices changed. More reports can mean more transactions crossed the same dollar threshold.

FinCEN Staffing Growth Versus Suspicious Activity Reports

FinCEN staffing growth versus suspicious activity reports shows a widening difference between reporting volume and the agency’s staff resources. In fiscal 2015, institutions filed 2,118,092 SARs and the agency reported 276 actual full-time equivalents. In fiscal 2022, SAR filings reached 4,307,713 while actual full-time equivalents stood at 286.

The workload also extends beyond SARs. Treasury’s fiscal 2024 budget justification records 26,930,703 Bank Secrecy Act reports filed in fiscal 2022. Those reports include several reporting populations, including cash transactions, cross-border currency movements and foreign financial accounts.

The Financial Crimes Enforcement Network shares the reporting data with authorized investigators at other agencies. They search it for leads and use it to advance investigations.

Staff shortages also reach sanctions investigations. The Government Accountability Office’s March 2020 sanctions resource study found that the Office of Foreign Assets Control had received additional hiring authority but left some authorized positions unfilled.

How Much CTR Data Do Investigators Access?

The Government Accountability Office’s figure below measures CTR access through the BSA Portal. Access through agencies’ own systems is not counted in that figure.

Investigators can also use information shown in search results or share a downloaded report without generating another portal access record.

What Happens When a Bank Files a Suspicious Activity Report?

A bank’s suspicious activity report becomes financial intelligence that authorized investigators can search, connect with other information and use to start or advance an investigation.

The Financial Crimes Enforcement Network’s fiscal 2025 review reports that 88.6% of IRS Criminal Investigation cases opened that year had a primary subject associated with at least one Bank Secrecy Act filing. It separately reports that 11.7% of investigations opened originated from a Bank Secrecy Act filing.

The investigator looking for a person or transaction may find information assembled by a bank long before the inquiry began. A useful report can connect an existing investigation to money the investigator had not yet traced.

More Reports Can Coexist With Missed Activity

Higher filing volume can reflect better detection, more suspicious activity or more defensive reporting. Anti-Money Laundering: Opportunities for Improvement, a white paper from the Wharton Initiative on Financial Policy and Regulation, explains why the volume trend alone cannot choose between those explanations:

The paper also describes extensive investigative use of Bank Secrecy Act information. More filings can help investigators, but volume alone says little about the quality of the leads.

The criminal case against TD Bank shows what can disappear behind a reporting total. In its 2024 guilty plea, the bank admitted failures involving its anti-money laundering program, accurate CTR filing and money laundering. The admitted conduct included budget constraints that left domestic automated clearing house transactions and most checks outside monitoring.

Someone deciding which payment channels the system examines shapes what the institution can discover. A filing total starts downstream of that decision. For investigators trying to trace criminal money, those excluded channels are missing pieces of the trail. For an insider who knows which activity management left outside review, the missing coverage is the story.

Whistleblower Rewards Follow a Separate Track

The anti-money laundering whistleblower law can pay whistleblowers collectively 10% to 30% of eligible government collections in covered enforcement actions over $1 million. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.

If you know who kept a payment channel outside monitoring, or how budget decisions overrode coverage, your information reaches behind the filing count. We assess which whistleblower program fits the conduct and how your knowledge connects management’s decisions to the activity investigators need to examine.
