Treasury Secretary Scott Bessent isn't mincing words when it comes to Iran's ruling class. In a video address Thursday announcing new sanctions, he delivered what might be the most colorful diplomatic warning of the year: Iranian leaders are moving money offshore "like rats on a sinking ship," and the U.S. is watching every transaction.

Following the Money Trail

Acting at President Donald Trump's direction, the Treasury Department rolled out sanctions targeting 18 individuals and entities connected to Iran's crackdown on protesters and elaborate sanctions evasion schemes. The list reads like a who's who of Tehran's security apparatus, including regional commanders from the Islamic Revolutionary Guard Corps and Law Enforcement Forces.

"My message today is to the Iranian leadership on behalf of people in Iran who cannot speak for themselves," Bessent said. "The central bank is broke and printing money. Hyperinflation is next."

Among those sanctioned is Ali Larijani, secretary of the Supreme Council for National Security, who according to the Treasury Department "has publicly called for Iranian security forces to use force to repress peaceful protesters." Other targets include officials allegedly behind shootings, hospital raids, and coercive tactics against demonstrators.

The sanctions also hit financial networks tied to Bank Melli and Shahr Bank, institutions accused of laundering proceeds from Iranian oil sales. These aren't small-time operations—they're the plumbing that keeps sanctioned Iranian oil money flowing through the global financial system.

A Warning With Bite

But it was Bessent's direct message to Iran's elite that grabbed attention. "U.S. Treasury knows that like rats on a sinking ship, you are frantically wiring funds stolen from Iranian families to banks and financial institutions around the world," he said in his statement on X. "Rest assured, we will track them and you."

The timing is notable. Just days earlier, Trump threatened 25% tariffs on any country still doing business with Iran, as anti-government protests continue roiling the country. The administration is clearly trying to squeeze Tehran from multiple angles simultaneously.

Energy Markets Shrug Off Geopolitical Drama

You might expect oil prices to jump when the U.S. announces sweeping sanctions on a major producer. Iran pumped out 4.70 million barrels per day of crude oil and natural gas in September 2025, according to the U.S. Energy Information Administration—that's roughly 4.4% of global output.

But markets barely flinched. WTI February Crude Oil futures dipped 0.19% Thursday night to $59.10 per barrel, while Brent March futures slipped 0.22% to $63.63 per barrel. February Natural Gas futures actually climbed 0.89% to $3.170 per MMbtu.

The United States Oil Fund LP (USO), which tracks light, sweet crude oil futures, fell 2.04% Thursday to close at $71.20, then edged up 0.20% in overnight trading. The fund shows weak momentum characteristics but maintains favorable price trends across short, medium, and long-term timeframes.

The market's calm response suggests traders either expect these sanctions won't meaningfully disrupt supply, or they're already priced in. Iranian oil has been flowing to willing buyers despite existing sanctions, often through creative shipping and documentation schemes. Whether this new crackdown changes that calculus remains to be seen.
