Voldemort to Iran. "Suck it! Here comes the blockade. Is it a crisis for them?

If it walks like a duck.

Yes it is a crisis. I'm not saying I'm enjoying this however. Like the pontiff I'm a man of piece...except where Gaza is concerned. I'm a member of tribe, you understand.

Trump’s Blockade Is a Crisis for Iran

The economic damage is immediate and threatens the regime if it lasts.

Iran’s regime has tried to make this war all about economics, and now it is getting its wish. Since Monday the U.S. Navy has quarantined Iranian ports, blocking ships from entering or exiting the Strait of Hormuz for the purpose of commerce with Iran. The economic damage to the regime is immediate, and the pain will grow the longer the blockade is sustained.

The best estimates we have are from the Foundation for Defense of Democracies’ Miad Maleki, who led the U.S. Treasury’s sanctions campaign against Iran until last year. He writes that the blockade is expected to wipe out $435 million in Iranian economic activity a day and force oil-field shut-ins within two weeks.

U.S. Central Command reported Tuesday that “no ships made it past the U.S. blockade and 6 merchant vessels complied with direction from U.S. forces to turn around” on day one. That’s good news, as Iran had been exporting some 1.5 million barrels of oil a day. This gusher, Iran’s main source of foreign currency, undercut U.S. efforts to pressure Iran—whose decision to block the Strait had been allowed to benefit the regime while choking everyone else.

Centcom said more than a dozen warships are executing the mission, which the U.S. can sustain. A dynamic to watch is whether tankers docking at Gulf Arab ports again begin moving through the Strait in numbers.

Oil prices stayed below $100 a barrel on news of some diplomatic progress, and the S&P 500 has already erased the wartime selloff, but the real solution is to end Iran’s blockade. Insofar as the new U.S. Navy action facilitates its de-mining and other preparations in the area, it’s doubly a threat to the regime.

Economic modeling by Mr. Maleki’s FDD colleagues, Elaine Dezenski and Daniel Swift, finds that the war’s current economic damage to Iran already exceeds 40% of its prewar GDP. This relies on an International Monetary Fund estimate of a 6.1% Iranian economic contraction in 2026, which they call conservative.

Mr. Maleki calculates that, without exports, surplus production would fill Iran’s oil storage capacity in about 13 days. Then Iran would have to shut-in wells, which can cause severe damage and cost it billions of dollars in annual revenue.

His conclusion? “Iran’s economic structure, heavily dependent on the Persian Gulf transit routes and energy exports, makes continued resistance economically impossible under the U.S. naval blockade.” That is, if it lasts. Iran’s regime could think President Trump won’t sustain the blockade beyond a week or two. He may have to prove it wrong with patience.

Iran’s entire economy will feel the collapse of oil exports. This includes the Revolutionary Guard, which siphons about half the revenue. Other export routes appear unable to compensate for the loss. How will Iran’s banks hold up?

The loss of imports is expected to deepen supply shortages and exacerbate Iran’s inflation, which exceeded 50% before the war. Food inflation had reached triple digits. The currency, which has lost more than 97% of its value since 2018, would also likely suffer without the foreign exchange coming in. Iran’s regime knows all this is a threat to its survival.

The regime has tried to protect itself from its own people by cutting off the internet, crushing the digital economy with it. The destruction of Iran’s productive capacity, especially in steel and petrochemicals and industries that rely on them, also portends layoffs and a spike in inflation, even without the blockade.

Oh, and the regime’s latest budget calls for tax increases. This is not a pretty picture. The shame is that this pressure didn’t begin weeks ago.
