Brent crude at $100 looms as twin chokepoint threats converge

Brent crude could surge past $100 a barrel if simultaneous closures of the Red Sea and Strait of Hormuz choke off supply, according to Kpler, with nearly 5 million barrels a day of refined products at risk.

"Crude oil at $100 per barrel is back on the agenda," Michelle Brouhard, Head of Policy and Geopolitical Risk at Kpler, said in an interview.

Bottlenecks are already forming in refined oil product shipments, with gasoline, diesel and jet fuel flows facing potential disruption, Brouhard said. The warning comes as Iran has threatened to block the Strait of Hormuz, through which about one-fifth of the world's oil supply transits daily. Brent crude has already risen in recent weeks as traders price in escalating Middle East tensions after the latest escalation in the region.

A sustained breach of $100 would mark the first time Brent has traded at that level since 2022, when Russia's invasion of Ukraine sent prices soaring. For central banks still battling inflation, a renewed oil spike would complicate rate-cut timelines and raise costs across transportation, logistics and manufacturing sectors globally.

Two chokepoints, one crisis

The Red Sea route has faced persistent disruptions from Houthi attacks on commercial shipping since late 2023, forcing tankers to divert around the Cape of Good Hope and adding weeks to transit times. A simultaneous closure of the Strait of Hormuz — a narrow waterway between Iran and Oman that handles roughly 20 million barrels of crude and products each day — would represent a supply shock without modern precedent. The last time both routes were simultaneously threatened was during the Iran-Iraq war in the 1980s, when the Tanker War disrupted shipping in the Persian Gulf and sent oil prices to multi-year highs.

The combined effect of both chokepoints being compromised would remove a significant portion of global seaborne oil trade from the market. OPEC's spare production capacity, estimated at roughly 4 million to 5 million barrels a day, would be insufficient to fully offset the loss, particularly if Iran — itself an OPEC member — is the party enforcing the Hormuz blockade. That gap between disrupted supply and available spare capacity is what makes the $100 scenario plausible, Brouhard said.

Iran's warning that not a single drop of oil would pass through Hormuz if provoked has heightened fears of a coordinated disruption. The 5 million barrels a day of refined products at risk — spanning gasoline, diesel and jet fuel — would hit global supply chains at a moment when refining capacity is already stretched, Brouhard said. Global refining margins have already widened as product inventories in key regions including Europe and Asia have drawn down faster than seasonal norms, she added.

What a $100 oil spike means for markets

An oil price surge to triple digits would ripple across asset classes. Energy stocks and oil producers would benefit from wider margins, while consumer discretionary sectors, airlines and logistics companies would face margin compression. The inflationary impulse would pressure central banks globally, potentially delaying rate cuts that markets have been pricing for the second half of 2026.

The last time Brent traded above $100 was in mid-2022, when the Russia-Ukraine war drove prices to a peak of $139 a barrel. That episode contributed to a global inflation surge that forced the Federal Reserve to hike rates at the fastest pace in four decades. A repeat scenario, even at a lower peak, would test the resilience of an economy still adjusting to higher borrowing costs.

For oil-importing nations in Asia — including India, Japan and South Korea, which rely heavily on Middle Eastern crude — a sustained price spike would widen current account deficits and put downward pressure on local currencies. Higher fuel costs would also feed into electricity prices in countries that rely on oil-fired power generation, adding another layer of inflationary pressure across emerging markets.
