Gas prices fall under $4 as US signs deal with Iran to end war

Gas prices fall under $4 as US signs deal with Iran to end war The preliminary agreement to reopen the Strait of Hormuz sent oil prices tumbling and gave crypto markets a fresh reason to rally Share Add us on Google by Editorial Team Jun. 18, 2026 For the first time since March 2026, the average price of gasoline in the United States dropped below the $4 mark. The catalyst: a memorandum of understanding between the US and Iran that promises to reopen one of the most important chokepoints for global energy supply.

The US national average hit $3.999 per gallon on June 18, down from levels that had been stubbornly parked above $4 for months. Brent crude fell over 4% toward $83 per barrel on the news, a dramatic swing for a commodity that had touched $120 per barrel earlier in 2026 when the conflict was at its most intense.

What the deal actually says President Donald Trump and Iranian President Masoud Pezeshkian signed the preliminary MoU on June 17-18, 2026. The core of the agreement centers on reopening the Strait of Hormuz, the narrow waterway between Iran and Oman that handles roughly 20% of the world’s oil shipments. Advertisement The initial terms call for toll-free passage through the strait for 60 days while Iran clears mines from the waterway.

That same 60-day window doubles as a negotiation period covering two of the thorniest issues in US-Iran relations: Iran’s nuclear program and sanctions relief on Iranian oil exports. Iran has reportedly agreed to diminish its stocks of highly enriched uranium as part of the broader framework. Oil’s wild year, in context Earlier in 2026, supply disruptions from the conflict drove Brent crude to $120 per barrel.

That translated directly into pain at the pump for American consumers, with gasoline prices climbing well above $4 and staying there. A drop from $120 to around $83 per barrel represents a roughly 30% decline in crude prices from the 2026 peak. What this means for crypto and risk assets Bitcoin had already climbed to a two-week high above $65,500 prior to the agreement, reflecting a broader market appetite for risk that the MoU appears to have reinforced.

Ether also moved higher, though specific figures were less dramatic. The logic chain works like this: lower oil prices reduce input costs across the economy, which softens inflation expectations, which makes it less likely the Federal Reserve keeps rates elevated or hikes further. Statements from the central bank have tempered some of the enthusiasm that the geopolitical thaw might otherwise have generated.

That 60-day clock is the variable to watch. If negotiations progress smoothly and sanctions relief materializes, Iranian oil flooding back onto global markets could push crude prices even lower. If talks collapse, the Strait of Hormuz could become contested again, oil prices could spike, and inflation fears that crypto markets had started to shake off would come roaring back.
