Oil Markets on Edge as Hormuz Traffic Halts

Oil markets erupted after tanker traffic through the Strait of Hormuz collapsed. Prices spiked as traders rushed to price the worst case. But the reality behind the disruption may look very different than the narrative driving the market.

Energy markets just experienced one of the most violent geopolitical shocks in modern history.

AIS traffic over the last ten days looks exactly like what you would expect when one of the world’s most important maritime arteries suddenly resembles a war zone: tanker movements collapsed and flows through the Strait of Hormuz fell off a cliff.

In reality, Lloyd’s of London likely did more to shut down the strait than the IRGC. Once war risk premiums exploded, most shipping companies simply refused to move through the area.

Yesterday we finally began to see a small trickle of vessels testing the route again.

That fragile recovery lasted less than a day.

Overnight two tankers were struck while transiting the strait, and traffic will likely disappear again until insurers, navies, and shipping companies reassess the risk.

Which matters because the Strait of Hormuz is not just another shipping lane.

Under normal conditions roughly 20 million barrels per day of crude, condensate, and refined products move through that narrow stretch of water. That represents about one fifth of global oil demand and nearly a quarter of all seaborne crude trade.

When traffic through that artery collapses, the oil market does not wait for confirmation.

It prices the worst case immediately.

And that is exactly what we just saw.

The Market Reaction

Oil prices reacted exactly how you would expect when traders suddenly have to price the possibility that one of the world’s largest energy arteries might remain offline.

Front month WTI exploded from the low 70s toward triple digits before settling back once policymakers began floating emergency reserve releases.

The first move was pure fear. Traders rapidly priced the possibility that the strait stays closed and the world suddenly loses access to a massive portion of prompt supply.

Strategic Reserves Enter the Picture

Governments quickly reached for the one lever they actually control: strategic reserves.

The International Energy Agency announced a coordinated release totaling roughly 400 million barrels across member nations.

The United States will carry much of that burden, releasing roughly 172 million barrels from the Strategic Petroleum Reserve over the next four months.

The SPR currently sits just above 415 million barrels, meaning the proposed draw would push inventories toward levels not seen since the late 1980s.

Llyod’s Stopping Power

The dominant narrative right now is simple: Hormuz is shut, global supply is collapsing, and oil prices must keep rising. However, this is a short-term hurdle.

The Iranian navy has largely begun its new role as an artificial coral reef. While the IRGC can harass traffic with small craft and drones, sustaining a long term blockade against Western naval forces is an entirely different problem.

They can disrupt traffic. They can damage ships. Permanently closing one of the busiest shipping lanes on Earth is far harder.

Once naval escorts stabilize the route and insurers begin recalculating risk, traffic could normalize faster than the market currently expects.

The China Pressure Valve

Roughly 80 percent of Hormuz oil flows to Asia, and China alone absorbs a massive portion of that supply.

Nearly 40 percent of the oil transiting the strait ultimately ends up in Chinese refineries.

If disruptions begin materially constraining those flows, Beijing has every incentive to pressure Tehran to stabilize the situation.

When nearly half your imported energy supply runs through a war zone, the phone calls tend to happen quickly.
