As the world watched anxiously on April 7, 2026, oil prices surged and markets trembled in response to President Donald Trump’s escalating threats against Iran. The president’s self-imposed deadline—8 p.m. Eastern Time for Tehran to reopen the vital Strait of Hormuz—sent shockwaves through global energy markets, raising the specter of a new and potentially catastrophic Middle East conflict.
Oil traders woke up to a volatile landscape. Brent crude, the international benchmark, climbed more than 1 percent to $111 a barrel, while West Texas Intermediate (WTI) crude jumped to about $116 a barrel, up more than 3 percent, according to BBC and The New York Times. By early afternoon in Europe, Brent was trading at $110.60, with New York light crude up 2.5% to $115.17 a barrel, as reported by Le Figaro. The price swings reflected not just the threat of military escalation, but the deep uncertainty gripping investors and policymakers alike.
President Trump’s rhetoric was nothing short of apocalyptic. “A whole civilization will die tonight, never to be brought back again,” he posted on Truth Social, as cited by CNBC and The Guardian. “I don’t want that to happen, but it probably will.” In a meeting with reporters, he doubled down, declaring, “The entire country could be taken out in one night, and that night might be tomorrow night.” The threats were not idle: U.S. forces had already bombed dozens of military targets on Iran’s Kharg Island, Iran’s key oil export hub, though officials insisted oil infrastructure was spared, according to NBC News.
The immediate trigger for this crisis was the closure of the Strait of Hormuz, a narrow waterway connecting the Persian Gulf and the Gulf of Oman. This channel is the world’s most important energy artery, carrying about one-fifth of all global oil and gas shipments. Since February 28, when the U.S.-Israel conflict with Iran flared up, Tehran has threatened to attack vessels transiting the strait in retaliation for airstrikes, severely disrupting energy flows. According to S&P Global Market Intelligence, only eight tankers passed through the strait on Monday, April 6, a far cry from the pre-war average of 20 million barrels per day in 2025.
The stakes could hardly be higher. The head of the International Energy Agency, Fatih Birol, told Le Figaro that the current oil and gas crisis is “more serious than the ones in 1973, 1979 and 2022 together.” The impact, he warned, will be felt most acutely by developing nations, which face higher prices for oil, gas, and food, and by major economies like Japan and South Korea, highly dependent on Middle Eastern energy.
Trump’s demands were clear: Iran must reopen the Strait of Hormuz and agree to a ceasefire, or face destruction of its bridges, power plants, and other civilian infrastructure. “They have 'til tomorrow,” he said Monday. “Now we’ll see what happens. I can tell you, they are negotiating, we think in good faith.” Yet, the president also admitted the outcome was far from certain, and market analysts agreed. “The situation has evolved into a near-term binary outcome: either escalation through direct strikes on Iranian infrastructure, or a last-minute de-escalation that could trigger a sharp reversal in risk assets,” said Daniela Hathorn, a senior market analyst at Capital.com, speaking to The Guardian.
Iran, for its part, has rejected U.S. proposals for a temporary ceasefire, instead demanding a permanent end to hostilities, the lifting of sanctions, and a protocol for safe passage through the strait. Axios reported that Tehran had presented a 10-point plan, including reconstruction efforts. Trump acknowledged, “They made a ... significant proposal. Not good enough, but they have made a very significant step. We will see what happens.”
While the world waited, the UK hosted a meeting of allied military planners to discuss securing the Strait of Hormuz once the conflict ends, the BBC reported. Trump also urged other countries to send warships to the region to ensure safe passage for oil and gas shipments. The disruptions have already had a ripple effect on global markets: Asian economies like Japan and South Korea have been particularly hard-hit, and the UK’s RAC reported “significant fuel price rises” over the Easter holiday, with petrol and diesel prices jumping several pence per litre.
Markets responded with their own brand of trepidation. Stock indices in Asia and Europe seesawed on Tuesday, reflecting the uncertainty. Japan’s Nikkei was flat, South Korea’s Kospi rose by 1.1%, while Hong Kong’s Hang Seng dropped by 0.7%. In Europe, the FTSE 100 and other major indices experienced similar volatility, with the Stoxx Europe 600 initially rising before dropping by 0.2% by early afternoon, according to Le Figaro.
The economic fallout is already being felt beyond the trading floor. Kristalina Georgieva, head of the International Monetary Fund, told Reuters that the war would likely lead to higher inflation and slower global growth. The IMF had previously anticipated a modest upgrade in global growth forecasts for 2026 and 2027, but now “all roads now lead to higher prices and slower growth.” In the UK, the effects are particularly acute: S&P Global reported that service sector growth was at its weakest in 11 months, and Thomas Pugh, chief economist at RSM UK, predicted another bout of stagflation, with recession looming if the conflict drags on.
Meanwhile, the fog of war has left analysts and investors guessing. Ed Yardeni, president of Yardeni Research, summed up the mood: “There is no way to predict the outcome. We can’t rule out that Iran will cave in. Or, Trump may postpone the deadline again, explaining that negotiations are making progress. Or the war will escalate. The fog of war remains thick.”
Even as a handful of tankers began to transit the strait again, Michael Wan, senior currency analyst at MUFG Research, cautioned that a full resumption of traffic would take time—at least three to six months for energy supplies to reach Asian economies facing shortages. Insurance costs for ships have soared, and the scramble for available shipments has driven prices even higher, as noted by Tineke Frikkee, a senior fund manager at W1M, speaking to the BBC.
With the deadline looming and the world’s energy arteries at risk, the outcome of this standoff remains uncertain. What is clear is that the crisis has already reshaped the global energy landscape and raised the stakes for international diplomacy in a way not seen since the oil shocks of the 20th century.
