Trump might have to maintain blockade for months before Iran feels pain

Locked in a standoff with Iran that will break only when economic pain is no longer tolerable, President Donald Trump may have to maintain his naval blockade against Iran for weeks — forcing serious economic consequences on the world.

Trump said Wednesday that he will keep the U.S. blockade against Iran in place until it agrees to a nuclear deal. Tehran, meanwhile, refuses to reopen the Strait of Hormuz until the U.S. calls off its Navy.

It’s unclear which side will budge first.

Trump said Sunday that Iran’s oil infrastructure is days away from exploding because crude is bottled up due to the blockade. 

“Something happens where it just explodes,” Trump told Fox News. “They say they have only three days left before that happens. When it explodes, you can never rebuild it the way it was.”  

But Iran has weeks of space left in its tanks to store oil that it can’t export, experts said. This should give Tehran time to ramp down oil fields in an orderly way that avoids permanent damage, they said.

The oil supply shock, meanwhile, grows worse every day Iran keeps the strait closed, putting pressure on the U.S. as the global economic damage mounts.

“The question for me is who has a longer runway — Trump or Iran,” said Fernando Ferreira, the head of Rapidan Energy’s geopolitical risk service.

Iran tankers blocked

Tehran will feel the heat from the U.S. blockade. There has been no confirmed passage of an Iranian tanker through the U.S blockade zone, according to the ship-tracking firm Kpler.

Iran-linked ships have crossed the strait but they did not make it past the blockade, which stretches from the Gulf of Oman to the Arabian Sea, according to Kpler.

Tehran is losing $500 million per day due to the blockade, a White House official told CNBC.

With Iran’s tankers hunted by the U.S. Navy, oil and condensate loadings at its ports have collapsed from 2.1 million barrels per day before the blockade to just 567,000 bpd after, Kpler found.

Iran will have to start filling up its storage tanks because the oil cannot be exported. Eventually, Tehran will have to cut oil production as the storage tanks near capacity.

Storage capacity

That is the point where Tehran would start feeling the squeeze but it could take a long time to force a reaction, according to Rapidan Energy.

“They prepared for a blockade,” Ferreira said. “They thought it through. They saw what happened in Venezuela.”

“They’re prepared to hold out for months,” the analyst said.

Iran has at least 26 days before its storage tanks fill and production cuts become unavoidable, Ferreira said. The estimate assumes 26 million barrels of onshore storage and 21 million barrels of floating storage in 18 empty, sanctioned tankers in the region, he said.

But it’s a conservative estimate, Ferreira cautioned. Iran’s maximum storage capacity suggests it has space for another 39 million barrels, giving it another 22 days beyond the 26, the analyst said.
