Sheinbaum Steps In to Delay U.S. Sanctions on Mexican Banks

Mexico’s new president scores a diplomatic win—but the accusations are still on the table

In what’s being called a behind-the-scenes lifeline, President Claudia Sheinbaum revealed Thursday morning that Mexico’s Ministry of Finance (SHCP) was directly responsible for securing a 45-day reprieve from U.S. sanctions against three Mexican financial institutions accused of laundering cartel cash.

CIBanco, Intercam, and Vector Casa de Bolsa were set to be effectively cut off from the U.S. financial system on July 21 after being labeled as “primary money laundering concerns” by the U.S. Treasury’s Financial Crimes Enforcement Network (FinCEN). The charges? Allegedly helping Mexican cartels move dirty money used in the fentanyl trade.

But thanks to a last-minute intervention from Hacienda, those sanctions won’t take effect until September 4. According to Sheinbaum, the extension was granted “at the request of our Ministry of Finance… we’re working closely with the banks and brokerage firm to resolve this.” One of the banks, she added, is having its trust operations temporarily taken over to prevent further problems.

Hacienda Calls It “Respect for Our Sovereignty”

Mexico’s Finance Ministry didn’t just pull diplomatic strings—they issued a formal thank-you to Washington, calling the delay the product of “dialogue and collaboration… within a framework of respect for our sovereignty.”

The U.S. side confirmed the extension in a July 9 press release, noting that Mexico had taken “further steps” to address concerns, including assuming temporary control of the three institutions. FinCEN Director Andrea Gacki described the move as “necessary to protect the U.S. financial system from abuse by illicit actors.”

So far, the joint efforts appear to be holding. But make no mistake: the accusations haven’t disappeared.

No Proof, Says Sheinbaum

Back in June, President Sheinbaum flatly denied the money laundering claims during a morning press conference, saying: “There’s no proof—only statements. If there is proof, we will act. But without proof, we can’t.”

Despite that, the accusations have already triggered fallout. Several U.S. and Mexican companies have suspended business with CIBanco, Intercam, and Vector while the legal dust settles.

Treasury’s orders were issued under the Fentanyl Sanctions Act and the FEND Off Fentanyl Act—two tools increasingly used by the U.S. government to hit cartels in the pocketbook by choking off their financial lifelines. According to FinCEN, the three firms were instrumental in laundering proceeds that helped manufacture and traffic fentanyl across borders.

Still on the Watchlist

With the clock now ticking toward the new September 4 deadline, both governments are scrambling to show compliance—or at least enough good faith—to avoid a full financial blacklisting.

Mexico’s financial authorities say they’re reinforcing oversight and internal controls at the institutions. Meanwhile, FinCEN is watching closely and has made it clear they’ll “consider all facts and circumstances” before deciding whether to grant any further delays.

As for Sheinbaum, this may be her first big international test as president. And while she’s bought some time, the real challenge lies in what happens next.

Stay tuned. This story’s far from over.

Border Slams Shut Again on Mexican Cattle Over Livestock Pest

If you blinked, you missed it. Just two days after the U.S. began reopening ports to Mexican cattle, the border has slammed shut—again.

On July 9, 2025, Brooke L. Rollins, head of the U.S. Department of Agriculture (USDA), ordered the immediate suspension of live animal imports—including cattle, bison, and horses—from Mexico. The reason? A fresh case of the dreaded gusano barrenador, or screwworm, was confirmed in Veracruz.

And that’s all it took.

No Moo-ving Past This

The U.S. had just started easing a nearly two-month-long embargo, beginning July 7 with a partial reopening at the Douglas, Arizona port. But with this new case, USDA hit pause on the entire plan. Upcoming reopenings in Columbus, Santa Teresa, Del Río, and Laredo are now in doubt. The ports were scheduled to resume trade throughout July and into September, depending on sanitary conditions.

According to Rollins, trade won’t restart until Mexico shows real progress in screwworm eradication. That includes strict quarantine measures, traceable cattle movement, and aggressive fly control.

Million-Dollar Maggots

The May 11 shutdown has cost Mexico dearly. The Mexican Meat Council estimates $700 million in losses due to 650,000 cattle being held up. That’s a lot of steaks and burgers stuck in limbo.

To contain the pest, Mexico and the U.S. have been deploying a weird but effective strategy: releasing over 100 million sterile flies per week. It’s pest control by overwhelming romance failure—and it’s been working. At least until now.

A new sterile fly facility is being built in southern Texas with an $8.5 million budget, and another in Metapa, Chiapas is being upgraded with $21 million. It’s a binational battle of bugs.

Mexico Responds

Mexico isn’t taking this lying down. Since July 7, new rules prohibit moving livestock from infected zones without a clean bill of health. SADER, Mexico’s agriculture department, is working closely with USDA and APHIS to stabilize the situation.

Still, President Claudia Sheinbaum isn’t thrilled. She’s expressed her government’s commitment to U.S. cooperation—but also criticized unilateral moves from the north. “Mexico isn’t anyone’s punching bag,” she’s said before. Apparently not even for maggots.

As of now, over 1,400 cases of animal screwworm infections and six human cases have been confirmed in Chiapas and Campeche. With health risks on both sides of the border, both countries know they’ve got more at stake than just lost exports.

So, when will the cattle flow again? Not until those worms stop burrowing and the flies stop flying—or at least, start dying without descendants. Stay tuned.
