Bessent tightens screws on Iran’s banks as gas holds at $4.33

Wars are fought with missiles, but they are paid for with money. Cut off the money, and the missiles eventually stop arriving.

For most Americans, though, the scoreboard isn’t in Tehran. It is on the sign at the corner gas station, which is why a sanctions fight over Iranian banks still reaches your budget.

That is the bet behind Operation Economic Outcast, the sanctions campaign the Treasury Department launched on Aug. 24. Since then, it has designated well over 100 Iran-linked targets across aviation, shipping, gold, autos, and rail, according to law firm Morgan Lewis.

The oil side of the squeeze is already severe. Iran’s seaborne crude exports fell to zero in the second week of September and were still at zero on Oct. 5, Reuters data showed, as a U.S. naval blockade choked off shipments.

That left Tehran leaning on the money it already has and the banks willing to move it. On Oct. 15, Treasury went after those banks.

“The noose is tightening around Iran’s economy, and not even Iran’s so-called allies can save it,” Treasury Secretary Scott Bessent said in a statement released by the Treasury Department. He added that Treasury will keep going until the regime’s coffers are empty.

Oct. 15 Iran sanctions round hits banks, not barrels

The centerpiece is the International Development Bank for Investment and Finance, an Iraq-based lender Treasury says gave Iran a door into the global financial system while supporting Iran’s proxy militia groups, according to the Treasury Department.

In total, the round named 16 individuals and 10 entities. They include two Iranian offshore banks tied to Bank Mellat and Bank Shahr, a Hong Kong trading company, four Iranian exchange houses, and an oil intermediary, Sayyed Ruhollah Razavi, who Treasury says moved millions of barrels a month for Iran’s national oil company before the blockade.

The dollar amounts are not small. One exchange house, Najafzadeh Exchange, processed transactions worth hundreds of millions of dollars for Iranian financial institutions, while two others each facilitated tens of millions of dollars in payments, Treasury said.

Seven employees of Farab Sorough Qeshm, an affiliate of Bank Shahr, were also named for coordinating foreign-exchange transactions through shell companies in Hong Kong and the United Arab Emirates, according to ANI’s report on the action.

Any assets the targets hold in the U.S. are now frozen, and foreign banks that knowingly handle significant transactions for them risk losing their U.S. correspondent accounts, Treasury said. For a bank in Baghdad or Hong Kong, that is the threat that counts.

The State Department separately designated Cuba-based Banco Internacional de Comercio for serving Iran’s Karafarin Bank since at least 2022, ANI reported. Earlier this month, Treasury also barred dealings with Russia’s A7 payment platform, Morgan Lewis noted.

I’ve followed this campaign since its Aug. 24 launch, and the target list has steadily moved from Iran itself to the countries and payment systems around it.

By my analysis, that map is the real message in Bessent’s “so-called allies” line. The money is moving through Iraq, Hong Kong, the United Arab Emirates, Cuba, and Russian payment rails, and Treasury is now naming each route.

Why the money trail still matters for oil prices

Iran isn’t selling crude at sea right now, so this round won’t pull new barrels off the market.

The bigger lever on prices is the Strait of Hormuz, where Iran’s Revolutionary Guard navy still says only ships it authorizes may pass, according to a Trading Economics market note from Oct. 18.

More on Bessent’s Iran campaign:

There is some relief on the supply side. U.S. Energy Secretary Chris Wright said Persian Gulf oil flows had recovered to around 80 percent of pre-war levels, though refined-fuel shipments remain tight, Trading Economics noted on Oct. 19.

Iraq is the exception worth watching. It is OPEC’s second-largest producer, and any move that rattles its banking system or its ties to Washington touches a country whose barrels the market still counts on.

Here is where energy markets stand as Treasury tightens the screws:

  • Brent crude traded around $108.65 a barrel on Oct. 19, up roughly 78 percent from a year earlier, according to Trading Economics.
  • Flows through Hormuz averaged 11.62 million barrels a day in the week to Oct. 13, against a pre-war baseline of 17.15 million, Trading Economics reported.
  • West Texas Intermediate crude settled at $95.09, and crude inventories fell 8.6 million barrels to about three percent below the five-year average, according to AAA.
  • The 10-year Treasury yield sat near 5.10 percent on Oct. 16, close to a 24-year high hit the week before, Benzinga noted.

What Bessent’s squeeze means for your wallet

You feel this at the pump first. The national average for regular gas was $4.3344 on Oct. 15, compared with $3.0674 a year earlier, according to AAA.

That gap is about $1.27 a gallon. On a 15-gallon fill-up, you are paying roughly $19 more than you did last fall, and if you fill up once a week, that adds up to nearly $990 a year.

Where you live matters even more. California drivers paid $6.23 a gallon on Oct. 15, while North Carolina drivers paid $3.70, AAA’s state data showed.

The second hit is quieter. Energy prices feed inflation, and inflation keeps long-term rates high. Futures traders priced an 85.1 percent chance the Federal Reserve holds rates steady in October, Benzinga reported, citing CME FedWatch. That means relief on mortgage and car-loan costs isn’t coming soon.

For your own budget, plan around today’s price, not the drop you hope for. If an extra $19 a week pinches, that is the line to trim elsewhere until tanker traffic recovers.

I don’t expect this sanctions round to move gas prices on its own. What it does is lengthen the standoff, and a longer standoff means Hormuz, not Treasury, keeps setting the price you pay.

Next moves to watch as Treasury tightens the noose

Treasury has been naming new targets almost weekly, and its Oct. 5 alert warned foreign banks that keep serving Iran that they risk losing access to the U.S. financial system, Morgan Lewis reported. The next round could reach bigger banks in bigger economies.

Watch two numbers: the AAA national average and daily Hormuz traffic. If ships begin moving freely again, your fill-up gets cheaper fast, whatever happens to Iran’s banks.

Until then, budget for $4 gas as the baseline. Bessent says the noose is tightening, and drivers are feeling the squeeze, too.
