The Trump Administration's War in Iran Is Harming Fishermen in Hawaii and Across the Country

Diesel costs are spiking in Hawaii as a result of the Trump administration’s war in Iran, placing serious strain on the state’s longline fishing fleet. On Oct. 23, 2026, diesel in Hawaii hit a record $7.2919 per gallon—up more than $2 in a year, nearly 40%. NOAA data show fuel is the single biggest expense for Hawaii trips, reaching up to half of trip costs; in 2023, 29 cents of every $1 in revenue went to fuel. With fish prices set at auction, fishermen can’t pass costs on, forcing hard choices between staying dockside or risking unprofitable trips.
