A deeper look at the diesel and gasoline markets moving 2026 marina prices — the same data behind every Market Pulse signal.
The 2026 closure of the Strait of Hormuz triggered the largest supply shock in the history of the oil market. Marine fuel has more than doubled since February — and it lands directly on your fill-up.
East Coast marina diesel now runs $3.60 to over $6.25 per gallon depending on the dock.
The cheapest and priciest docks in one waterway regularly differ by more than $2.00 a gallon.
It's tied to global freight routed through the Strait — making timing intelligence a financial necessity.
2026 didn't just feel expensive. Across 35+ years of weekly U.S. gasoline data it ranks #2 for annual increase, yearly peak, and single-week spike — a rare cluster of near-records in one season.
