FinCEN Southwest Border MSB Geographic Targeting Order — original $200 CTR threshold (March 2025)

Mechanism

FinCEN exercised authority under 31 USC 5326 (BSA recordkeeping/reporting GTO authority, capped at 180 days). The order modifies, geographically and quantitatively, the standard CTR regime that otherwise applies only to single-day cash transactions exceeding $10,000:

• Threshold: lowered from $10,000 to $200. CTRs required on any cash

transaction by, through, or to the MSB more than $200 but ≤ $10,000.

• Geography: 30 ZIP codes across seven counties — Imperial (CA),

San Diego (CA), Cameron (TX), El Paso (TX), Hidalgo (TX), Maverick (TX), Webb (TX). Selection was driven by FinCEN/IRS-CI/HSI typology work identifying these strips as cartel-adjacent cash-corridor concentrations.

• Filing window: 30 days (vs. the standard 15-day BSA window).
• Covered population: every MSB physically located in a covered ZIP —

i.e., licensed money transmitters, currency exchangers, check cashers, prepaid-access providers operating retail locations in those ZIPs. Banks and credit unions are not MSBs and are not covered.

• Duration: 180 days from effective date — April 14, 2025 to

September 9, 2025. (This is the statutory ceiling for a §5326 GTO; any continuation requires a fresh order.)

The GTO is part of a broader Trump-administration post-January-2025 cartel-targeting policy stack: EO 14157 (FTO/SDGT designation of cartels), the §5326 GTO here, the IEEPA fentanyl tariffs on Mexico/Canada/China (2025-02-01), and the subsequent §2313a special-measure orders against CIBanco, Intercam, and Vector (2025-06-25). The GTO is the lowest-friction of those instruments — no FR notice-and-comment, just an order — and it became the template for the September 2025 modification, the January 2026 Minnesota healthcare-fraud GTO, and the March 2026 expansion.

Downstream implications

• US/MX retail cash-corridor compliance friction: covered MSBs must file

CTRs at a 50× lower threshold, and the 30-day window doesn't fully offset the volume burden.

• Reading-of-the-tape signal: published as a regulatory order rather than

a statutory amendment, the GTO surfaces FinCEN's threshold willingness to treat narrow geographic strips as enhanced-AML zones, including under the FTO/SDGT cartel framing established in EO 14157.

• Set the operational precedent for the September 2025 threshold change

($200 → $1,000) and the Arizona / inland-NM expansion in 2026.

Open questions

• Volume impact: how many additional CTRs were filed during the

April 14 – September 9 window? FinCEN has not published throughput.

• Diversion effects: did transactions migrate just outside covered ZIP

codes, or to non-MSB rails (banks, crypto)?

• Did any MSB litigation challenge the order under §5326 procedural or

Fourth-Amendment lines? (None known as of filing date.)
