Trump’s New Cuba Sanctions Threaten Foreign Banks With Secondary Penalties

On May 1, 2026, President Trump signed a new executive order under the International Emergency Economic Powers Act (IEEPA) that ratchets up sanctions against Cuba to an unprecedented level. This order doesn’t just reinforce existing Cuba trade and travel restrictions—it introduces aggressive secondary sanctions aimed squarely at foreign financial institutions that engage with Cuban entities linked to the government’s energy, defense, mining, financial services, and security sectors.

For decades, U.S. sanctions on Cuba have primarily relied on the Trading With the Enemy Act and the Helms-Burton Act, focusing on broad trade embargoes and restrictions on U.S. persons traveling to Cuba. But by invoking IEEPA, the administration has unlocked a more powerful enforcement tool that mirrors the tough sanctions regimes used against Iran and Russia. This means foreign banks, investment firms, and even insurance companies face the real risk of losing access to the U.S. financial system if they process what the Treasury Department deems “significant transactions” involving designated Cuban entities.

The executive order authorizes the Treasury and State Departments to designate any foreign person or entity operating in specified Cuban sectors or supporting the Cuban government, including those involved in serious human rights abuses or corruption. Once designated, these persons’ U.S.-based assets are frozen, and U.S. persons are barred from any dealings with them. The order also suspends entry into the U.S. for designated individuals, unless national interests dictate otherwise.

What makes this executive order particularly menacing is its broad scope. The U.S. government can add new Cuban sectors to the sanctions list at will, and it targets not only direct Cuban government actors but also their families and anyone materially assisting them. This creates a chilling effect across the Cuban economy and signals a robust, ongoing campaign to isolate Cuba financially.

Financial institutions worldwide should take note: the definition of “foreign financial institution” here is expansive, covering banks, money service businesses, securities dealers, and more. This is not just about traditional banks; a wide range of financial entities could face penalties. While the order does not specify what counts as a “significant transaction,” Treasury’s Office of Foreign Assets Control (OFAC) has historically used a broad, fact-based approach to enforcement under similar sanctions programs.

This new Cuba sanctions regime fits a broader pattern of the Trump administration’s authoritarian overreach—using executive power to bypass Congress, escalate pressure on foreign governments, and weaponize economic policy to punish political adversaries. It also underscores the administration’s willingness to impose sweeping restrictions that extend well beyond U.S. borders, threatening the global financial system’s openness and stability.

For companies and financial institutions with any ties to Cuba, the message is clear: tread carefully or risk severe consequences. The Trump administration is signaling a new era of aggressive sanctions enforcement, and no one connected to Cuba’s government or economy is safe from scrutiny and penalty.

We will continue to track developments as the State and Treasury Departments roll out specific designations and enforcement actions under this order. Stay tuned.
