The conflict has exposed the real bottleneck in the global energy system. It’s not crude supply but refining capacity.
Around a fifth of Middle Eastern refining capacity is offline because of war damage or export disruptions. Chinese refinery activity is running well below year-ago levels, and Russian refinery throughput remains constrained by Ukrainian drone attacks.
Combined, these disruptions reduced global refinery runs in August by roughly 4 million bpd, or 5%, from a year earlier, according to Energy Aspects.
The result is a growing shortage of fuels.
That distinction matters politically for the Trump administration because voters buy gasoline, not crude oil.
U.S. gasoline prices have risen roughly 30% over the past year, while diesel prices have surged more than 50%. Even if additional crude begins flowing through Hormuz, rebuilding refining capacity will take far longer.
The administration's options for bringing down domestic fuel prices are narrowing by the day.
Recent White House moves underscore these limitations.
On Monday, U.S. Treasury Secretary Scott Bessent expanded sanctions against Tehran and threatened secondary measures against countries continuing to do business with it, describing the campaign as an "economic D-Day."
Yet sanctions are unlikely to deliver breakthroughs, and threats of secondary sanctions hold little weight when Bessent has made clear that Washington seeks to avoid actions that could seriously upset the global economy.
That reduces the likelihood that the U.S. will impose severe penalties on China, Tehran's largest oil customer – one of the few economic measures that could move the needle with Iran.
Washington is also attempting to jawbone markets by arguing that oil flows through Hormuz are recovering rapidly despite Iranian threats.
Over the past week, senior White House officials have argued that Gulf exports are approaching pre-war levels as more tankers depart under U.S. naval protection, with their transponders turned off. Energy Secretary Chris Wright said on Friday that the seven-day average for oil leaving Hormuz had climbed above 8 million bpd.
However, shipping analytics firms monitoring Hormuz through satellite imagery and vessel-tracking data see little evidence of a recovery.
Oil exports through the strait have averaged just 2.2 million bpd so far in August, according to Kpler. Total regional crude exports, including shipments from Saudi and Emirati ports that bypass Hormuz, averaged about 9 million bpd this month, down from 11 million bpd in July and roughly 17 million bpd in 2025.
While the administration may be seeking a deal behind the scenes, the contrast between Washington's public claims and the data suggests desperation rather than strength.
