The United States and Iran reached a framework agreement on June 15 to end their war, sending oil prices tumbling and stock markets soaring worldwide. Brent crude fell more than 5% to $82.84 per barrel, the lowest level since the conflict closed the Strait of Hormuz on February 28. The deal promises to reopen this critical shipping route, through which 20% of the world’s oil and liquefied natural gas normally flows. Global stock markets rallied on hopes the energy crisis will ease.
How Far Oil Has Fallen Since the Deal
Brent crude dropped more than 5% to $82.84 per barrel following the framework announcement. Before the war began on February 28, oil traded around $70 per barrel. During the conflict, prices peaked at about $120 per barrel as the Strait of Hormuz closure disrupted global energy supplies. The latest drop reflects market relief that a major supply disruption may soon end. However, oil futures for next year show traders expect prices to stay well above pre-war levels for months.
Stock Markets Rally Worldwide on Peace Hopes
Global stock markets surged on the deal announcement. Japan’s Nikkei 225 closed 5% higher, while South Korea’s Kospi ended up 5.2%. The S&P 500 rose 1.7%, the Dow Jones climbed 0.9% to a record, and the Nasdaq jumped 3.1%. Asian markets benefited most because they rely heavily on Middle East oil and liquefied natural gas. Airlines and cruise operators posted sharp gains. United Airlines rose 3.9%, and Royal Caribbean Group jumped 6.6% on expectations of lower fuel costs. In London, the FTSE 100 slipped 0.4% as energy stocks BP and Shell fell on lower oil prices.
When Will Fuel Prices Actually Drop?
Experts warn that relief at the pump will take months, not weeks. The Strait of Hormuz must be cleared of naval mines before ships can safely pass, a process that could take 40 to 50 days. Even after mine removal, tankers stuck in the Persian Gulf need time to load and transit to Asia. A round trip to Japan takes 45 to 50 days. In the US, petrol prices averaged $4.06 per gallon on June 16, down from a peak of $4.48 in early May but still $1.08 per gallon higher than on February 28. Energy analysts estimate it will take months for prices to return to pre-war levels, even if the deal holds.
Uncertainty Remains Before the Official Signing
Pakistan, which mediated the talks, announced an official signing ceremony for June 19 in Switzerland. However, key details of the agreement remain undisclosed. Vandana Hari from energy analysis firm Vanda Insights warned that the lack of detail is “likely to inject unease and uncertainty into the market” and could trigger volatility this week. The deal extends the current ceasefire for at least 60 days while broader talks on Iran’s nuclear program continue. Shipping firms remain cautious about using the strait until war-risk insurance costs fall and independent observers verify the waterway is safe.
Final Thoughts
Brent crude fell 5% to $82.84 per barrel on the US-Iran peace deal, but consumers should expect months of waiting for fuel prices to normalize. Mine clearance, tanker repositioning, and insurance concerns will delay full supply restoration through the Strait of Hormuz.
