The two-week ceasefire announced on April 7, 2026, between the U.S. and Iran has triggered a massive "risk-off" move in the energy markets. While crude futures plunged 15% overnight, the impact on refined products (gasoline, diesel, and jet fuel) will vary by region due to local inventory levels and shipping logistics.
Gasoline & Diesel: Expect a steady, albeit "lagging," decline at the pump. Retail prices are projected to drop 10–15% over the next two weeks as the $20 "war premium" evaporates from WTI crude.
Jet Fuel: Immediate relief for domestic carriers; surcharge pressures will ease as Gulf Coast refining margins stabilize.
Diesel & Heating Oil: Prices remain sensitive but are easing from record March highs. The spread remains volatile, but the reopening of the Strait of Hormuz reduces the need for expensive, long-haul Atlantic substitutes.
Refining Margins: Will remain elevated due to low inventories, preventing a total price collapse to pre-war levels.
Industrial Fuels & Naphtha: The biggest winners. As the primary consumers of Persian Gulf crude, Asian markets will see a sharp drop in Official Selling Prices (OSPs) and the disappearance of the $20–$30 spot premiums that plagued the region in March.
Shipping: Regional fuel costs will drop significantly as "war risk" insurance premiums for tankers in the Arabian Sea are slashed.
Export Stability: Local product prices will stabilize as refineries in the UAE and Saudi Arabia resume full operations without the threat of infrastructure strikes.
Developing Markets: Nations in East Africa and South Asia, hit hardest by the $110+ peak, will see crucial inflationary relief, though the temporary nature of the ceasefire (14 days) keeps long-term hedging costs high.
Import Costs: Major importers like Brazil and Chile will see immediate balance-of-payment relief; however, domestic price-smoothing policies may mean consumers don't see the full benefit for 3–4 weeks.
