US Revokes Waiver Allowing Iran Oil Sales After Attacks

Washington on Tuesday revoked an authorization that had allowed Iranian oil sales after attacks on commercial tankers in and near the Strait of Hormuz, tightening pressure on Tehran and adding to a risk premium in energy markets.

U.S. officials said the step followed Iran’s conduct in the waterway, with one official saying Iran would receive benefits only if it showed “good behavior” and calling the actions in the strait unacceptable. Crude prices moved higher as traders weighed the threat to shipments through one of the world’s most important oil transit routes.

The move came less than three weeks after an interim arrangement reached on June 17 under which Iran had agreed to safe passage for commercial shipping through Hormuz. On Tuesday, a fresh round of attacks hit tankers in or near the strait. After those incidents, Washington withdrew the oil-sales authorization that had been part of the earlier understanding.

A U.S.-led maritime coordination center said three vessels were attacked on Tuesday: a liquefied natural gas tanker, an oil supertanker and a third tanker that was not further identified.

The same center raised the threat level for ships crossing Hormuz to “severe” and warned mariners that “deliberate hostile action” by Iran was likely under current conditions.

The warning matters because Hormuz sits at the mouth of the Persian Gulf and handles a large share of globally traded crude and refined fuels, making even isolated incidents relevant to shipping costs and energy pricing.

For the oil market, the immediate issue is not only whether barrels are lost but whether shipowners, insurers and charterers begin treating the route as materially less secure. Higher war-risk premiums, slower sailings, route changes and delays can lift transport costs quickly, even if the strait remains open.

The mix of vessels involved in Tuesday’s incidents also unders cores that concern is not limited to a single cargo stream: an LNG carrier and a crude supertanker were both targeted, suggesting risks that could spill across gas and oil logistics if tensions persist. That helps explain the market reaction,

which reflected concern over a chokepoint rather than confirmed evidence of a broad supply outage.

Key details remain unsettled. Public reporting has not established the full extent of damage to the vessels, whether cargo movements were disrupted, or the precise legal mechanics of the authorization Washington revoked, and it is not yet clear whether the step is intended as a one-off response or the start of a broader tightening of sanctions.

What is clearer is the sequence. An interim shipping arrangement announced on June 17 was followed by tanker attacks on Tuesday, a “severe” threat warning for Hormuz traffic, and then a U.S. decision to pull back oil-sales relief for Iran.

If maritime security in the strait stabilizes, some of the added fear premium in crude could ease; if incidents continue, the pressure is likely to show up first in tanker traffic, insurance costs and energy-market volatility.
