Oil Flows Through Hormuz: Officials Claim 7 Million Barrels Daily, Industry Pushes Back

 

Houston — U.S. Energy Secretary Chris Wright stood before energy executives and told them the military had helped restore significant oil traffic out of the Persian Gulf. Roughly 7 million barrels a day now move with American support. That figure, he said, represents about half the volume trapped when the U.S.-Israeli conflict with Iran began earlier this year.

Short. Direct. Yet the room stirred. Minutes later Chevron Chairman and CEO Mike Wirth took the stage at the same Bloomberg Energy Security Executive Briefing. His assessment differed. “It’s probably not quite that much,” Wirth said, according to reporting by Argus Media.

The exchange on June 12 laid bare a deeper tension. Official optimism collides with operational reality in one of the world’s most critical energy chokepoints. Pre-war flows through the Strait of Hormuz averaged more than 20 million barrels per day of crude and products. The narrow passage carries one-fifth of global petroleum. When Iran retaliated after strikes in late February, tanker traffic collapsed. Ships piled up. Markets tightened. Prices spiked.

Wright’s Assessment Meets Industry Skepticism

Wright’s remarks carried the weight of policy. The U.S. military escorts vessels. Volumes are rising. “No Iranian crude is getting out of the Strait of Hormuz,” he added, per Reuters. He expects full reopening if diplomacy advances. And the numbers matter. They signal progress toward stabilizing supplies strained since the February escalation that shut the strait for weeks.

But executives live with daily shipping data. Wirth described ships moving at night. Transponders switched off. Some military support involved. Yet he questioned the scale of 7 million barrels. His comments echoed earlier cautions from Chevron. In May the CEO had warned of physical shortages rippling through global systems. He noted multiple vessel attacks that week. Traffic then ran at roughly 10% of normal levels.

So what explains the gap? Independent trackers show mixed signals. Some days record only a handful of transits. Others capture more dark fleet activity — ships operating without AIS signals. Windward maritime intelligence reported eight Iranian oil vessels loading in June, seven transiting dark. Yet total volumes remain far below pre-conflict averages. The U.S. Energy Information Administration pegged 2025 flows near 21 million barrels daily before disruption.

Analysts watch pipelines that bypass the strait. Saudi East-West lines. UAE routes to Fujairah. Those alternatives absorbed some crude early on. They can’t replace the full seaborne trade. Nor do they move products as easily. The result? Regional inventories built up. Asian buyers scrambled. Refiners adjusted runs.

Wright spoke with confidence. The U.S. has degraded Iranian naval capacity. Escorts grow more routine. Volumes edge higher each week. Bloomberg reporters at the event noted his prediction of complete reopening “with or without Iran’s assistance.” That stance aligns with administration messaging. President Trump earlier claimed secret operations moved over 100 million barrels. Wright later distanced from specifics of those claims in hearings but affirmed military facilitation of some flows.

Industry voices stay measured. Frontline CEO Lars Barstad told CNBC on June 11 that credible U.S.-Iran agreement could lift traffic quickly. Yet he doubted return to 130 or 140 daily vessels anytime soon. Current numbers hover far lower. Six transits on some recent days. A spike to 35 on others. Inconsistent. Hard to average with precision.

The disagreement highlights information challenges in contested waters. Satellite data. Insurance records. Port logs. Each offers partial views. Dark fleets complicate counts further. Lloyd’s List analysts tracked 36 transits in early June, half without signals. Such opacity fuels debate over exact barrels moving today.

Markets reacted in real time. Oil prices eased after Wright’s comments and earlier remarks about rising traffic. Yet futures curves still reflect risk. Physical tightness persists. Gasoline cracks in some regions widened. Inventory draws appear in Asia and Europe.

Longer term questions loom. Even if diplomacy restores access, rebuilding trust will take time. Shipowners remember attacks. Insurers demand higher premiums. Buyers prefer proven routes. Alternative infrastructure projects — more pipelines, storage — could gain momentum regardless of short-term deals.

Implications for Global Supply Chains

Energy security looks different after these months of disruption. The U.S. Strategic Petroleum Reserve played a role, with talk of refilling at favorable terms once flows normalize. Wright mentioned potential gains there. Yet reliance on military escorts for commercial traffic raises strategic issues. Allies and rivals watch closely.

Chevron’s presence in the region adds weight to Wirth’s caution. The company operates vessels in the Gulf. It maintains terminals and partnerships. Its executives see the logistics up close. When Wirth says the figure is probably lower, traders listen. Refiners adjust hedges. Governments review emergency plans.

Recent reporting reinforces the split view. Politico detailed the escort mission growth. E&E News highlighted rising volumes under military protection. Yet Al Jazeera and The Guardian examined Trump’s bolder claims and Wright’s more limited congressional testimony days earlier. Consistency remains elusive.

One fact stands clear. The strait matters. A single tanker carries two million barrels. A few dozen change global balances. Disruptions here ripple to pumps in California, factories in Germany, power plants in India. The current partial recovery offers relief but not resolution.

Executives left the Houston briefing with mixed signals. Official numbers point to progress. On-the-water experience suggests caution. Both matter. Policymakers will cite the 7 million figure in coming weeks. Companies will plan around more conservative estimates. The truth, as always in energy, lies somewhere between data points and direct observation.

And the clock ticks. Summer demand rises. Any renewed closure could ignite prices fast. Any sustained reopening could ease them just as quickly. For now the flow continues — escorted, partial, and disputed.
