Oil Drops 5% on Iran Ceasefire Signals as Physical Disruption Persists

Brent crude fell 5% to $65.99 a barrel on Wednesday and WTI dropped 5.11% to $61.92, as Trump's comments that Iran is "seriously talking" about a deal stripped out much of the war premium markets had built since late February. The selloff erased more than half the premium accumulated since February 28, when Iran's closure of the Strait of Hormuz sent crude to its highest level in four years. Prices have ranged between $61 and $138 since the conflict began. Trump's remarks followed ceasefire negotiations in Muscat and came with a caveat: a military strike remains on the table. Hours later, Iranian officials reported a U.S. ceasefire violation, and U.S. Central Command confirmed Marines had boarded and redirected the Iranian-flagged M/T Celestial Sea in the Gulf of Oman — the fifth vessel seized since the U.S. Navy blockade began in mid-April. The two-week ceasefire that started April 8 has lurched toward collapse multiple times, with Trump setting and then abandoning several deadlines. The price drop triggered a broad equity rally. Japan's Nikkei jumped 5%, South Korea's Kospi surged 8%, and the S&P 500 gained 2.5%. The FTSE 100 rose 1.8%, its biggest single-day gain in nearly a year. Energy stocks moved the other way — Chevron, Exxon Mobil, and ConocoPhillips each fell 3% to 4%. Airlines gained, with United up 6% and Delta up 5%, as investors priced in lower jet fuel costs. The price move is almost entirely diplomatic signal. Physical supply has not improved. Iraq, Saudi Arabia, Kuwait, the UAE, Qatar, and Bahrain collectively shut in 10.5 million b/d in April, and the Strait remains effectively closed to commercial traffic. Some 1,550 ships from 87 countries are stranded. The UAE's departure from OPEC on May 1 cut the cartel's spare capacity to 2.5 million b/d, and OPEC+ has paused planned production increases through March. Global oil inventories are forecast to fall 2.6 million b/d in 2026, with a sharper 8.5 million b/d draw expected in the second quarter. That deficit limits downside even if talks produce a breakthrough. Citi expects Brent to rebound toward $120 near-term, citing underpriced disruption risk. Wood Mackenzie puts $200 oil on the table if the Strait stays shut through summer. The gap between current prices and those forecasts reflects how much uncertainty traders are pricing into the diplomatic timeline. The next signals to watch are shipping data through Hormuz and Trump's next public statement on Iran. His pattern of escalation followed by pullback has whipsawed the market repeatedly since early April. Until tankers actually transit the Strait again, the ceasefire trade is a bet on presidential rhetoric, not restored barrels.
