Brent crude oil plunged 15% to $92 per barrel Wednesday morning before recovering slightly, wiping out $13 billion in speculative positions as Iran agreed to reopen the Strait of Hormuz under a two-week ceasefire with the United States. The crash — oil's biggest single-day drop since COVID lockdowns — reveals how much of the recent price surge came from war fears rather than actual supply disruptions.
Global stock markets surged on the news, with the S&P 500 closing up 2.5% and European indices posting even bigger gains. Germany's DAX jumped 4.7%, while Japan's Nikkei soared 5.4% as investors rushed back into risk assets.
The ceasefire announcement came after Trump's Tuesday evening ultimatum threatening that "a whole civilisation will die tonight" unless Iran reopened the crucial waterway by midnight GMT. Iranian Foreign Minister Abbas Araghchi responded that Tehran would ensure "safe passage through the Strait of Hormuz will be possible" if attacks against Iran ceased.
The dramatic price swing exposes how speculative premiums, not physical shortages, drove oil above $100 per barrel during the conflict. "Trump was likely wary about letting energy prices skyrocket by escalating the conflict," said Xavier Smith from AlphaSense. "That could have led to a self-inflicted economic wound that few would risk, especially given the looming pressure of approval ratings."
The $25 Billion Damage Bill
Even with the ceasefire, energy infrastructure across the Gulf remains severely damaged. Qatar's Ras Laffan industrial hub, which produces a fifth of global liquefied natural gas, has seen export capacity drop 17% with repairs taking up to five years.
Exxon reported Wednesday that its Middle East oil production fell 6% in Q1 2026 compared to 2025. Research firm Rystad Energy estimates total infrastructure repairs could cost over $25 billion and take years to complete.
The conflict's economic ripples extend far beyond oil prices. Airlines across Asia have raised fares and cut flights due to soaring jet fuel costs. Developing nations without sufficient refinery capacity or reserves have been hit hardest, according to Ichiro Kutani from Japan's Institute of Energy Economics.
Fragile Peace, Volatile Markets
Already on Wednesday, reports emerged of continued attacks in the region, which Pakistani Prime Minister Shehbaz Sharif said undermined "the spirit of peace process." Analyst Saul Kavonic from MST Marquee warned that full energy production won't resume until there's confidence in lasting peace.
"While a ceasefire is in place, it is still unlikely that energy production in the Middle East will fully resume until there is confidence of a lasting peace deal," Kavonic said. Some ships have passed through the strait in recent days, though far fewer than usual.
The two-week ceasefire timeline suggests both sides view this as a temporary pause rather than a permanent resolution. Energy markets, having been burned by geopolitical volatility, may price in continued risk premiums even as tankers resume normal passage through the world's most crucial oil chokepoint.
