Strait of Hormuz Tensions: Impact on Global Oil Supply and Prices

Oil prices have remained relatively stable despite a 100-day closure of the Strait of Hormuz because lost Gulf oil exports are smaller than initial market forecasts and “dark” oil shipments have increased, according to reports from Reuters and Bloomberg. The closure, which began approximately March 6, 2026, has not triggered the expected price surge due to a combination of clandestine shipping and lower-than-anticipated export losses.

Traders and shippers report that the volume of oil lost from Gulf exports is far smaller than analysts originally estimated, according to Reuters. This discrepancy suggests that the global market has absorbed the disruption more effectively than predicted during the early stages of the blockade.

Why haven’t oil prices spiked during the closure?

The lack of a price surge is attributed to a shift in how oil is moving out of the region. Bloomberg reports that shipowners are seeing a swell in “dark” oil flows. These are shipments that bypass official tracking systems and regulatory oversight to move crude despite the official closure of the waterway.

This clandestine activity has created a shadow supply chain that mitigates the impact of the blocked strait. While official channels remain restricted, the increased volume of untracked tankers has prevented a severe supply crunch that would typically drive prices higher.

The market’s reaction contrasts sharply with the initial expectations detailed by WIRED, which noted that the 100-day duration of the closure should have theoretically pushed prices to record highs. The Reuters data on lower-than-expected export losses provides the quantitative explanation for this market resilience.

How has U.S. intervention affected oil flow?

Military and logistical support from the United States has failed to restore significant commercial traffic to the strait. The New York Times reports that very little oil has actually gone through the Strait of Hormuz, despite ongoing U.S. efforts to secure the passage.

The failure of these efforts indicates that the physical or political risks associated with the closure outweigh the security guarantees provided by the U.S. Navy. This has forced the industry to rely more heavily on the aforementioned “dark” flows and alternative routes where available.

What triggers a return to normal shipping?

Industry executives believe that a diplomatic resolution is the only viable path to restoring standard commercial traffic. A tanker CEO told CNBC that ship traffic would likely increase quickly if the U.S. and Iran reach a formal deal.

The potential for such a deal is tied to the current administration’s approach to Iran. The market is currently weighing the likelihood of a negotiated settlement, which would remove the risk premium that continues to affect shipping insurance and route planning for legitimate tankers.

Comparing market expectations vs. reality

The current situation reveals a divide between perceived risk and actual supply loss. The following points highlight the contrast in reporting across major financial outlets as of June 14, 2026:

• Perceived Risk: WIRED frames the 100-day closure as a phenomenon that should have fundamentally altered oil pricing.
• Actual Volume: Reuters reports that the actual loss in Gulf exports is significantly lower than what traders first feared.
• Shipping Method: Bloomberg identifies a rise in “dark” oil as a primary reason for the stability, while The New York Times emphasizes that official U.S.-backed transit remains negligible.

This suggests that the oil market is currently operating on two tiers: a stalled official trade route and a thriving, untracked shadow market. The stability of prices is not a sign that the closure is irrelevant, but rather that the industry has adapted through non-traditional means.

Shipowners remain on edge, according to Bloomberg, as they wait for news that could either formalize these shadow flows or shut them down. The volatility remains latent, tied directly to the diplomatic relationship between Washington and Tehran.
