KEY POINTS
- Brent crude traded above $100 a barrel Monday morning, down from an April peak of $126 but still up more than 50% since the Strait of Hormuz closure began on February 28.
- The IEA has classified the disruption as the largest supply shock in the history of the global oil market, with cumulative losses exceeding 1 billion barrels and 14 million barrels per day shut in.
- Traders should watch for signs of sustained tanker traffic resumption through the Strait, which Bloomberg reported showed limited improvement last week, and for OPEC+ emergency production signals.
One hundred dollars a barrel is not a crisis price for oil. It is a reminder that the crisis has not ended.
Brent crude opened Monday's session holding above the $100 mark, trading in a range that has persisted for most of May after the violent swings of March and April. West Texas Intermediate tracked alongside, also near $100. The numbers look calmer than they did six weeks ago, when Brent spiked to $126 on April 7. But calmer is not calm. The Strait of Hormuz remains effectively closed for the third consecutive month, and the structural supply deficit is deepening every week.
The Scale of the Disruption
The International Energy Agency's May oil market report did not mince words. The Hormuz closure has shut in more than 14 million barrels per day, making it the largest supply disruption in the history of the global oil market. Cumulative losses since February 28 have exceeded 1 billion barrels. Global inventories fell from roughly 8 billion barrels at the end of February to approximately 7.8 billion by the end of April, and the IEA warned they could approach a historic low of 7.6 billion barrels by month-end.
Those numbers are not abstractions. They translate directly into the $4.50 national average gasoline price that American drivers are paying at the pump — a 44% increase from one year ago. In California, the average has hit $6.15. Only two states, Oklahoma and Mississippi, still have averages below $4.00.
Limited Relief on the Horizon
Bloomberg reported last week that the number of supertankers hauling unsanctioned oil through the Strait has shown signs of marginally increasing, but the volumes are a fraction of pre-crisis levels. The EIA's latest data showed Hormuz oil flows fell nearly 30% in the first quarter compared to the same period last year, and that figure likely understates the ongoing disruption because it includes January and most of February, when the Strait was still open.
The diplomatic picture offers no near-term resolution. The United Kingdom announced this month the deployment of Royal Navy assets to secure commercial shipping, joining a multinational coalition that underscores how far the situation has deteriorated from a regional conflict to a global logistics crisis.
How Energy Is Repricing Everything
The cascading effects have moved well past the oil patch. The World Bank warned in late April that the conflict would trigger the largest energy price surge since Russia's 2022 invasion of Ukraine, projecting a 24% average increase in energy prices for 2026. Diesel prices have surged more than 70% in Malaysia and over 85% in the UAE. Liquefied natural gas flows through the Strait have been disrupted alongside crude, creating a secondary shock to Asian power markets that depend on Gulf LNG imports.
For equity markets, the transmission mechanism runs through two channels. The first is direct: energy-intensive sectors from airlines to industrials face margin compression that no amount of hedging can fully offset at these prices. The second is indirect: energy-driven inflation feeds into consumer prices, which feeds into bond yields, which feeds into equity valuations. The 10-year Treasury yield's climb to 4.59% last week was not a coincidence. It was the bond market pricing in the reality that the Fed cannot cut rates into a 3.8% CPI print driven by a supply shock it cannot control.
Ryanair's decision last week to withhold profit guidance for the current financial year, citing poor visibility and surging fuel costs, is a preview of what more corporate managements may do if Brent stays above $100 through the summer.
What to Watch Next
The oil market's next major catalyst is twofold. First, any credible diplomatic signal toward Hormuz reopening would trigger an immediate correction in crude, but analysts estimate that even a ceasefire would require two months before steady export flows resume and potentially six months for full infrastructure recovery. Second, OPEC+ spare capacity is the only realistic near-term offset. Saudi Arabia and the UAE have the barrels, but deploying them requires navigating alliance politics that are more complex now than at any point since 2020. If Brent breaks decisively above $110 again, the pressure for an emergency production increase becomes politically unavoidable.
