U.S. naval escorts and regional pipelines have helped restore crude exports through Hormuz to something close to the prewar rhythm. Kpler said Wednesday that crude crossing the strait hit a seven day rolling rate of 13.5 million barrels a day as of Monday, lining up with its prewar benchmark for that corridor. Zooming out, combined Persian Gulf and Red Sea crude shipments hit 19.5 million bpd on that seven-day metric, exceeding Kpler's estimate for the corridor before the war of about 17 million bpd.
Not every piece of the system is healing at the same speed. Refined products through Hormuz were running at 677,000 bpd as of Monday on a seven day basis, compared with 3.6 million bpd before the war. Taken together, crude plus product flows stood at 14.2 million bpd, or about four fifths of the strait's prewar level.
Tehran has repeatedly asserted control over the waterway and has declared the strait closed multiple times during the war. Yet the volumes tell a different story. Matt Smith, Kpler's director of commodity research, said Tehran's influence is waning as strong shipments continue through Hormuz.
The barrels may be back, but the risks aren't. Iran is still firing on tankers in attacks that have at times been deadly. To limit exposure, more than 70% of crude that crossed Hormuz in August switched ships off the coasts of the United Arab Emirates or Oman, according to Kpler.
In this setup, shuttle tankers move oil through Hormuz into the Gulf of Oman, where the cargo is transferred to another vessel headed to Asia. The U.S. military shields this shuttle system, which reduces the chance of exposure to Iranian attacks, but it is uncertain how long that level of protection can continue.
"It's very expensive and it's a huge U.S. military commitment," said Helima Croft of RBC Capital Markets, who heads global commodity strategy. She also said Gulf producers do not view this patchwork of escorts and ship-to-ship transfers as an acceptable alternative to a fully open Hormuz.
Pipelines in Saudi Arabia and the United Arab Emirates are carrying more of the load too. About 40% of Gulf crude now avoids the strait via pipelines, up from 17% before the war, Kpler data show. But fixed infrastructure is vulnerable.

Saudi Arabia shut its East-West pipeline earlier this month after a drone strike launched from Iraq damaged it. Loadings later rose at the Red Sea port of Yanbu, a sign the line is running again. During the outage, Riyadh kept exports moving by shifting barrels back through Hormuz using the U.S.-protected shuttle system.
The imbalance between crude and products is showing up in prices and policy chatter. Natasha Kaneva, who leads global commodities strategy at JPMorgan, said the "crude market has largely normalized even as refined product supplies remain constrained." With Middle East fuel shipments tight and Ukraine striking Russian refineries, the world is facing a fuel crunch.
In the U.S., diesel has hit record highs, raising fresh worries about the broader economy. "The biggest source of pain is the diesel market," said Francisco Blanch of Bank of America on CNBC's Squawk on the Street on Sept. 8. Amid pressure from Republican lawmakers before the midterm elections, President Donald Trump is weighing an export ban. "There are some in Washington who say, let the blockade do its work - we can wait out Iran," said Helima Croft on CNBC's Power Lunch on Sept. 25.
Kpler reports that Iran's crude sales have collapsed while the U.S. Navy maintains a blockade of the Islamic Republic and Washington intensifies sanctions. Treasury Secretary Scott Bessent, speaking Sunday on Fox News, said Iran will complete the last of its crude shipments to China in about two weeks, after which they will have "nothing left to trade for anything."
There is little evidence pressure alone will shift Tehran's stance. On CNBC's Squawk on The Street on Monday, Scott Modell - the CEO of Rapidan Energy who previously served as a CIA officer - said, "There is no hard evidence that U.S. economic pressure will fundamentally change Iran's positions."
Last week, Tehran proposed reopening Hormuz within seven days provided the U.S. returns to the June memorandum of understanding. That MOU stipulated that the U.S. would end the blockade and permit Iran to hold talks with Oman about a future administrative framework for Hormuz. The arrangement fell apart over the summer and fighting resumed. Trump rejected Iran's most recent proposal, and, according to unnamed U.S. officials quoted by The Wall Street Journal, told aides that after the midterm elections he expects to resume bombing Iran.
"The president I think is going to escalate after the midterms, we keep hearing that the Iranians are going to esclatate into the miderms," Modell said. "The direction of travel is toward escalation."
For anyone budgeting real-world fuel costs, the takeaway is straightforward. Crude volumes look healthy, but products are lagging and the security setup is costly and fragile. Any hit to the shuttle system, a pipeline, or diplomacy could squeeze supply again fast. Watching the bypass share, refined product throughput, and the cadence of attacks will tell you how durable this recovery really is.
