Global oil prices climbed above $100 a barrel on March 9 as the widening war involving Iran, the United States, and Israel triggered fresh supply fears across energy markets. Al Jazeera reported that U.S. West Texas Intermediate crude futures jumped more than 20% to $111.24 a barrel, while Brent crude rose to $111.04, marking the first return to triple-digit oil prices since 2022.
The price surge reflects more than headline risk. It follows a week of escalating disruption across the Gulf, where attacks, shipping paralysis, and storage constraints have already forced producers and exporters to adjust operations. Reuters reported earlier that Brent had settled at $92.69 a barrel on March 6 and that the market was already pricing in a severe supply shock linked to the conflict.
Strait of Hormuz disruption is driving the market
At the center of the sell-off in supply confidence is the Strait of Hormuz, one of the world’s most important oil chokepoints. The U.S. Energy Information Administration says the strait carried more than one-fifth of global petroleum liquids consumption and over one-quarter of global seaborne oil trade in early 2025.
Al Jazeera reported that tankers had piled up on both sides of the waterway as insurers and shipowners reacted to attacks and the threat of further escalation. Reuters also reported that ship owners, major oil companies, and trading houses had suspended crude oil, fuel, and liquefied natural gas shipments through the strait, helping keep prices elevated.
Gulf production cuts are tightening the squeeze
The jump above $100 also comes as major Gulf producers curb output or manage flows more cautiously. Reuters reported that Iraq’s oil production had fallen sharply because blocked exports and limited storage left the country unable to maintain normal operations. Reuters also reported that ADNOC was managing offshore output while keeping onshore operations running, and that Saudi Aramco had begun reducing output at two oilfields amid the regional disruption.
The broader picture now includes precautionary reductions and operational adjustments across several Gulf producers, including Iraq, Kuwait, the UAE, and Saudi Arabia. That matters because the market is no longer reacting only to fear of disruption. It is reacting to actual losses, delayed shipments, and limited export flexibility.
Key numbers markets are watching
Investors are now focused on a narrow set of indicators that will determine whether this becomes a short-lived shock or a more durable oil crisis:
WTI crude: up more than 20% to $111.24 a barrel on March 9.
Brent crude: up to $111.04 a barrel, its first move back above $100 since 2022.
Hormuz exposure: more than 20% of global petroleum liquids consumption and over 25% of seaborne oil trade.
OPEC+ April plan: eight producers had already agreed on March 1 to raise output by 206,000 barrels per day, though current disruption is limiting the market impact of that move.
Inflation risks are back in focus
The oil rally is reviving fears of a new inflation shock. The International Monetary Fund has found that a 10% increase in global oil price inflation tends to raise domestic inflation by about 0.4 percentage point on average. That makes the latest surge significant for central banks that had hoped to keep easing price pressures in 2026.
The next phase will depend on whether shipping through Hormuz normalizes and whether producers can offset lost volumes quickly enough to reassure buyers. Until then, the return of triple-digit oil is likely to keep pressure on fuel costs, freight prices, and inflation expectations well beyond the Middle East.
