Global oil prices surged on Monday, April 27, 2026, as high-stakes peace negotiations between the United States and Iran stalled, heightening fears of a prolonged energy supply squeeze. Brent crude jumped nearly 3% to settle at $108.36 per barrel, its highest level in three weeks, while U.S. West Texas Intermediate (WTI) rose to $96.85. The market rally was triggered by the collapse of planned face-to-face talks in Islamabad after U.S. President Donald Trump scrapped his envoys’ visit, stating there was “no point sitting around talking about nothing.” This diplomatic friction follows a weekend of shuttle diplomacy by Iranian Foreign Minister Abbas Araghchi, who traveled to Oman and Russia after failing to reach a breakthrough with American officials in Pakistan.
The core of the deadlock lies in a “new proposal” submitted by Tehran, which offers to reopen the critical Strait of Hormuz and end the two-month-old war in exchange for lifting the U.S. naval blockade. However, the proposal pointedly defers negotiations regarding Iran’s nuclear program to a later stage—a condition that President Trump has signaled is a non-starter. With the Strait of Hormuz currently handling only a fraction of its usual 20 million barrels per day, analysts warn that the standoff is keeping approximately 10 to 13 million barrels of oil off the international market daily.
As rival blockades persist, Goldman Sachs has revised its year-end price forecasts upward, citing the “unprecedented scale of the shock” to global refining and supply chains. While both nations have indicated that active hostilities may not immediately resume despite the expired ceasefire window, the lack of a clear path toward a permanent treaty has left investors bracing for continued volatility. Market experts suggest that until a “zero-enrichment” agreement or a verified reopening of maritime chokepoints is reached, the risk premium on crude will remain significantly elevated, threatening to push prices toward the $115 mark in the coming weeks.
