The Gulf conflict's costs are now showing up in two places at once: in a U.S. fuel price at an all-time high, and in trade flows that have not recovered since ships began avoiding Bab el-Mandeb.
The U.S. national average price of diesel reached $6.05 a gallon on Friday, an all-time high and more than 60% above the $3.71 average of a year earlier, according to AAA data. A separate reading puts the figure above $6.06.
Diesel is the freight economy's input cost. It moves through trucking rates, rail, agricultural equipment, and construction before it reaches anything a consumer buys directly, and it does so with a lag. A 60% year-over-year increase in that input has not yet finished passing through, which is the reason this print matters more for the inflation picture than a comparable move in gasoline would.
The Red Sea has not recovered
The corridor at the other end of the disruption tells a longer story. Shipping volume through the Red Sea fell 50% to 55% between 2023 and 2025, and Suez Canal revenue took a roughly $7 billion hit, about 60%, across 2023 and 2024. Vessels rerouting around the Cape of Good Hope add more than 20 days to a transit. Those are the figures attached to a disruption that began well before this year's escalation and never reversed.
Bab el-Mandeb carries roughly 12% of global trade, including 11% of seaborne oil and 8% of liquefied natural gas. The strait's exact share of world commerce is quoted differently depending on whether the measure is tonnage, cargo value or vessel count, and the figures do not reconcile precisely. The orders of magnitude agree.
The escalation continues
Houthi forces claimed a large-scale ballistic missile and drone attack on Saudi Arabia's King Khalid Air Base at Khamis Mushait, asserting direct hits. Saudi Arabia has not confirmed or responded to the claim, which stands as an assertion by one party to the conflict and nothing more.
The humanitarian dimension is moving faster than the commercial one. More than 2,000 Yemeni refugees reached Djibouti within a single 24-hour period.
Why the pump price is the transmission channel
For markets, the significance of the diesel record is that it converts a geopolitical event into a domestic inflation input on a schedule nobody controls. Crude above $100 is a headline. Diesel at $6.05 is a cost already sitting inside freight contracts, and it arrives two days before a Federal Reserve decision in which inflation expectations are the explicit subject of the argument.
