Brent crude holds above $103 as Strait of Hormuz closure drags on

Brent crude oil settled above $103 per barrel on Sunday with no sign that the Strait of Hormuz will reopen anytime soon. The waterway, which runs between Iran and Oman, normally carries roughly 20% of the world's oil supply. Since Iran began restricting commercial vessel transit, Gulf producers have been unable to move at least 10 million barrels per day to international markets. The International Energy Agency has called it the largest disruption to global energy supplies in recorded history.

That figure matters. The 1973 Arab oil embargo cut global supply by about 5 million barrels per day at its peak. The current disruption is roughly double that, and it is not a deliberate production cut by exporters trying to push prices up. It is a physical blockage. Tankers cannot move. That distinction changes the calculus for everyone from energy traders to airline fuel buyers to governments managing strategic petroleum reserves.

What $103 oil actually means for everyday costs

At $103 per barrel, Brent is trading at a level not sustained for an extended period since mid-2014. For consumers, the downstream effects are already visible. Retail gasoline prices in the United States crossed $4.50 per gallon on average last week according to the Energy Information Administration. In Germany, diesel prices hit 2.10 euros per liter. Jet fuel surcharges on long-haul flights have risen by an average of $80 per ticket on routes served by European carriers since the crisis began.

Heating oil and natural gas prices are also climbing, partly because some utilities that would normally use gas are switching to oil where possible, and partly because liquefied natural gas tankers passing through the region face the same transit restrictions as crude carriers. For countries in South and Southeast Asia that depend heavily on Gulf energy imports, the situation is more acute. India, which imports about 45% of its crude from Gulf producers, has begun drawing down its strategic reserves while its refiners scramble to source replacement barrels from West Africa and the United States.

The joint statement from 22 nations and what it can realistically do

Twenty-two countries issued a joint statement on Sunday calling on Iran to cease attacks on commercial vessels and reopen the strait immediately. The signatories include the United States, the United Kingdom, France, Germany, Japan, South Korea, and Australia. The statement was firm in tone but contained no specific threat of military action and no new sanctions beyond those already in place.

Diplomatic statements of this type have a mixed track record in changing Iranian behavior. Iran did not alter its conduct after a similar 17-nation statement in January 2024 following Houthi attacks on Red Sea shipping, a crisis that persisted for months and added roughly $500 per container to Asia-Europe freight rates. The Hormuz situation is more severe in scale, but the diplomatic tools available to the international community have not meaningfully changed.

Iran has not formally acknowledged closing the strait. Its official position is that it is conducting legitimate military operations in response to attacks on Iranian territory. That framing matters legally and diplomatically because it affects which international frameworks apply and which countries are willing to take action beyond issuing statements.

Strategic reserves and alternative supply routes

The United States authorized a release of 30 million barrels from the Strategic Petroleum Reserve earlier this month, coordinated with IEA member countries releasing a combined 60 million barrels. That sounds large until you do the math. At 10 million barrels per day of lost Gulf output, the coordinated release covers about six days of the shortfall. It was designed to calm markets and signal coordination, not to replace Gulf supply over an extended period.

Saudi Arabia and the UAE have pipeline capacity that bypasses the strait entirely. Saudi Arabia's East-West Pipeline can move about 5 million barrels per day to Red Sea terminals, and the Abu Dhabi Crude Oil Pipeline can carry up to 1.5 million barrels per day to the port of Fujairah on the Gulf of Oman. Both pipelines are operating at maximum capacity. Combined, they offset less than half of the blocked seaborne volume, which means the market shortfall is real and will not be resolved by rerouting alone.

How long markets expect the disruption to last

Options markets are currently pricing in elevated volatility through at least the third quarter of 2026. Brent call options at $120 have seen a sharp rise in open interest over the past two weeks, which means traders are paying real money to hedge against prices moving significantly higher. That is not a forecast, but it tells you what the people with the most at stake are worried about.

Goldman Sachs published a note on Friday projecting that Brent would average $108 per barrel through Q2 2026 if the strait remains closed, rising to $118 if the disruption extends into Q3. Morgan Stanley's commodity team put out a more conservative estimate of $105 as a Q2 average, citing demand destruction as a moderating factor. When oil prices rise sharply and stay elevated, industrial demand does eventually soften. But that process takes months to work through the economy, and prices will stay high while it does.

The next formal IEA emergency meeting is scheduled for Thursday, March 26. The agenda will include a review of member country reserve release capacity and an updated assessment of how much non-Gulf supply can be accelerated in the short term, primarily from the United States, Canada, Brazil, and Norway.
