From the Financial Crimes Enforcement Network (FinCEN), full 2025 Suspicious Activity Report (SAR) numbers have arrived, revealing notable patterns across ACH, wire transfers, check payment systems and credit and debit cards. Using collected SAR filings through 2014 by payment system, here’s the visual trend through 2025:

When comparing 2024 to 2025 SAR filings per payment system:

• ACH: 316,786 total filings, up 8.3%
• Wire Transfers: 130,382 total filings, up 7.4%
• Checks: 475,878 total filings, down 8.7%
• Credit and Debit Cards: 316,786 total filings, up 6.2%

Only checks declined in SAR filings year-over-year, while ACH, wire and card filings increased. ACH, wire, and card volumes continue to grow as check volumes decline, as more account holders digitize transactions. Check-fraud related SARs remain significantly higher in 2025 compared to five years ago. 

Five-year SAR growth per payment system (since 2020) shows:

• ACH: 55% increase
• Wire Transfers: 149% increase
• Checks: 119% increase
• Credit and Debit Cards: 138% increase

Check and card SAR filings spiked notably in 2022, but ACH fraud has been growing steadily since 2018, accelerating sharply after 2020. Nacha’s ongoing awareness of credit-push fraud (including publications and new Rules releases) has helped slow growth. Wire transfers, however, remain on an “increasing at an increasing rate” trajectory, which could possibly be tied to heightened investment fraud as reported by the FBI, with $6.5 billion in losses during 2024 alone.

What’s driving these trends? According to FinCEN, notable fraud types listed through 2025 SAR filings include:
