For the first time since March 2026, the average price of gasoline in the United States fell below the $4 mark. This change stems from a new memorandum of understanding between the U.S. and Iran, which aims to reopen a vital chokepoint for global energy supply, specifically the Strait of Hormuz.
As of June 18, the national average price registered at $3.999 per gallon, marking a significant decrease from months of prices that remained stubbornly above $4. In response to this development, Brent crude oil prices decreased by over 4%, reaching around $83 per barrel—a stark contrast to the approximately $120 per barrel that occurred earlier amidst intense conflict in 2026.
#What Are the Main Points of the Agreement?
The preliminary memorandum of understanding was signed by President Donald Trump and Iranian President Masoud Pezeshkian on June 17-18, 2026. A key focus of the agreement is the reopening of the Strait of Hormuz, a narrow waterway that facilitates roughly 20% of the world’s oil shipments.
According to the initial terms, Iran will permit toll-free passage through the Strait for 60 days while they work to remove mines from the waterway. This timeframe also serves as a negotiation period for pressing issues, including Iran’s nuclear program and the potential lifting of sanctions on Iranian oil exports. Reports suggest that Iran has agreed to reduce its stockpile of highly enriched uranium as part of this larger framework.
#What Impact Did Oil Prices Have Earlier This Year?
In early 2026, disruptions in oil supply caused Brent crude to surge to $120 per barrel, translating to significant increases at the gas station for U.S. consumers. The fall from $120 to around $83 a barrel equates to a roughly 30% decline in crude prices from the peak earlier this year.
#How Might These Changes Affect Cryptocurrency and Other Risk Assets?
Leading up to the agreement, Bitcoin had already rebounded to a two-week high above $65,500, demonstrating a growing market interest in riskier assets, a trend likely reinforced by the newly signed memorandum. While Ether also saw gains, those figures were less pronounced.
The reasoning is straightforward: lower oil prices reduce overall business costs, easing inflation expectations. This dynamic lowers the chances that the Federal Reserve will maintain high interest rates or pursue further hikes. However, recent statements from the Fed have tempered some of the enthusiasm linked to the geopolitical stabilization.
The next 60 days will be crucial to monitor. If diplomatic efforts unfold positively and sanctions on Iran are lifted, the influx of Iranian oil could further depress crude prices. Conversely, if negotiations fail, the potential for renewed instability in the Strait of Hormuz could lead to rising oil prices, reigniting inflation concerns and impacting the cryptocurrency landscape.
