Brent Crude Surges Past $115 as Trump Signals Extended Iran Naval Blockade

April 29, 2026 — Brent crude oil climbed above $115 per barrel on Wednesday after President Donald Trump ordered preparations for an extended naval blockade of Iranian ports, intensifying what the International Energy Agency called the largest supply shock on record. The move, announced on April 29, marks the eighth straight session of gains for the international benchmark, reaching its highest level since June 2022.

Immediate Details & Direct Quotes

Trump directed aides to prepare for prolonged naval operations blocking Iranian ports after peace talks collapsed in Pakistan in mid-April without an agreement. The Strait of Hormuz, a critical chokepoint handling roughly 20% of global oil and liquefied natural gas shipments, has remained effectively closed since late February, with Iran restricting tanker traffic to near zero in response to U.S. military pressure.

“Trump said Iran has called for the U.S. to lift its naval blockade while negotiations continue,” the report states. On Truth Social, Trump told Iran to “get smart soon” and sign a deal, framing the blockade as a lower-risk alternative to resumed airstrikes.

West Texas Intermediate (WTI) crude, the U.S. benchmark, rose above $102 per barrel, gaining for the third straight session amid mounting uncertainty around global supply. The Iranian rial crashed to a record low of approximately 1.8 million per U.S. dollar, while the country reports 53.7% inflation and millions of job losses linked to the conflict.

Market Context & Reaction

The oil rally has sent shockwaves through global markets. The average price for a gallon of regular gas hit $4.229, the highest since Aug. 2, 2022, as fuel costs remain heavily influenced by oil prices, which account for more than half of the price at the pump. With refiners transitioning to pricier summer-blend gasoline, further pressure is expected heading into peak driving season.

U.S. equity markets edged lower on April 29 as the oil rally compounded existing uncertainty. The S&P 500 slipped 0.20%, the Dow Jones Industrial Average lost 0.27%, and the Nasdaq fell 0.41%. European markets also softened, with the FTSE 100 off 0.73% and the pan-European Stoxx 600 down 0.4%.

The 10-year U.S. Treasury yield ticked up to 4.39%, reflecting inflation worries tied to rising energy costs. The Federal Reserve is widely expected to hold rates steady at its meeting today, with Chair Jerome Powell likely to reiterate that policymakers remain data-dependent amid elevated inflation risks.

Background & Historical Context

The Strait of Hormuz closure has triggered what the World Bank forecast could be a 24% rise in energy prices overall this year under prolonged disruptions—the steepest projected increase since Russia’s invasion of Ukraine in 2022. Prices have swung sharply since the conflict began, with Brent nearing $120 per barrel at earlier peaks before pulling back on ceasefire hopes.

The UAE announced it will exit OPEC on May 1 to gain production flexibility, though analysts say that move does little to ease the immediate supply crunch while Hormuz remains closed. Tehran has vowed to keep disrupting Hormuz traffic, claiming it can manage through alternative routes, while Washington is stepping up pressure with potential sanctions targeting Chinese refiners and countries paying transit fees through Hormuz.

A ceasefire that had been in place since early April remains fragile. The confluent of Big Tech earnings, a Fed decision, and an oil shock driven by geopolitics has left traders with little margin for error, as markets remain highly fluid.

What This Means

Any breakthrough in U.S.-Iran talks or an agreement to reopen the strait could quickly reverse the oil rally, as prior ceasefire announcements have shown. Until then, traders are watching energy supply data, Fed signals, and geopolitical dispatches closely.

The Federal Reserve’s decision today, expected to hold rates steady, will provide key signals on inflation risks. Chair Powell’s comments ahead of his term concluding in May are in focus, while the Senate Banking Committee voted 13-11 Wednesday to advance Kevin Warsh’s nomination as the next Fed chair.

For investors and consumers, prolonged supply disruptions could maintain upward pressure on fuel costs through peak driving season, while any de-escalation could provide immediate relief. The situation remains highly volatile, with markets responsive to each geopolitical development.
