World Oil Prices Surge to Near $113 as US-Iran Conflict Disrupts Strait of Hormuz Flows on March 23, 2026

Global oil prices climbed sharply Monday amid persistent disruptions to the Strait of Hormuz caused by the ongoing U.S.-Iran conflict, with Brent crude benchmark rising to around $113 per barrel as supply fears intensified in the fourth week of hostilities.

Brent crude futures settled near $113.52 per barrel on March 23, up about 1.18% from the previous session, according to Trading Economics data. The international benchmark has surged more than 60% over the past month and stands about 55% higher than a year ago, reflecting severe market anxiety over energy chokepoint risks. West Texas Intermediate (WTI) crude, the U.S. benchmark, traded around $99.88 per barrel, up roughly 1.68%, with intraday highs pushing past $100 in electronic trading.

The price spike stems directly from the U.S.-led military operations against Iran that began in late February 2026, escalating into sustained exchanges that have effectively throttled maritime traffic through the Strait of Hormuz. The narrow waterway, linking the Persian Gulf to the Arabian Sea, handles about 20% of global seaborne oil trade — roughly 20 million barrels per day under normal conditions — plus significant liquefied natural gas volumes.

Since early March, tanker transits have plummeted to a fraction of usual levels. Automatic identification system data from maritime intelligence firms show daily passages dropping from over 150 vessels pre-conflict to as few as 13 in early sessions, with only sporadic oil tankers getting through. The International Energy Agency described the situation as the "largest global oil supply disruption in history" in its March report, noting flows reduced to "a trickle" and limited bypass options available.

Iranian threats to close the strait entirely, combined with U.S. naval deployments to secure lanes and Israeli strikes on Iranian energy infrastructure, have deterred shippers. Reports indicate at least 21 vessels targeted or hit since hostilities began, prompting rerouting or halts. Even China-linked tankers, which might have enjoyed some leniency, faced restrictions, with Beijing reportedly directing refiners to curb exports amid supply concerns.

The disruption has compounded existing pressures on global energy markets. Brent briefly approached $120 earlier in March before paring back on hopes of de-escalation, but Trump's 48-hour ultimatum to Tehran late last week — threatening further action if shipping lanes remain blocked — reignited upside momentum. Analysts at Goldman Sachs and BloombergNEF note a substantial risk premium baked into prices, estimating $13 or more per barrel tied to a potential one-month full closure scenario.

Broader economic fallout continues to unfold. Gasoline prices in the U.S. have risen sharply, with national averages nearing $3.50-$3.60 per gallon and California exceeding $5 in some areas, per AAA reports. European natural gas benchmarks jumped 25-60%, while Asian importers face acute inflation from higher transport and manufacturing costs. The International Energy Agency warned of the "greatest global energy and food security challenge in history," as fertilizer and chemical exports through the strait have also been curtailed, threatening agriculture worldwide.

Market reactions extended beyond commodities. Asian stock indexes fell more than 5% in early trading Monday, with Japan's Nikkei and South Korea's Kospi leading declines amid risk aversion. U.S. equity futures pointed lower, though some resilience appeared as traders weighed the possibility of diplomatic breakthroughs via Oman or Egypt.

Forecasts vary on duration and peak impact. Trading Economics projects Brent averaging $112.57 by quarter-end, potentially climbing to $126.42 in 12 months if tensions persist. BloombergNEF scenarios suggest averages could hit $91 in late 2026 under prolonged Iranian export halts, though baseline views assume eventual stabilization. The U.S. Energy Information Administration's Short-Term Energy Outlook anticipates Brent remaining above $95 through mid-2026 before easing toward $80 in the third quarter, contingent on supply restoration.

OPEC+ producers have yet to announce coordinated responses, though spare capacity discussions have surfaced. Saudi Arabia and other Gulf states, reliant on the strait for exports, face their own vulnerabilities, with some vessels reportedly using alternative routes at higher costs.

For consumers, the surge translates to immediate pain at the pump and in heating bills. Airlines, shipping firms and energy-intensive industries report margin squeezes, with some passing costs to customers. Central banks, already navigating post-pandemic inflation, face renewed challenges as higher energy prices feed into broader indices.

As trading progresses into the New York session, attention remains on diplomatic signals and any new military developments. A resolution or partial reopening of the strait could trigger a sharp pullback; continued blockages risk pushing benchmarks toward $120 or higher, amplifying recession fears in vulnerable economies.

The conflict's energy dimension underscores the fragility of global supply chains in geopolitically tense regions. With no quick end in sight, oil markets brace for volatility as the world weighs the costs of prolonged disruption.
