• The US has declared a passage in the Strait of Hormuz open for free transit, according to a statement by US official Cooper.
  • The announcement comes amid heightened naval activity and competing claims over the strategic chokepoint.
  • Global oil markets remain on edge, with shipping firms adjusting routes and insurance costs rising.

Open Passage Declared

The United States has opened a passage in the Strait of Hormuz for free passage, a US official identified as Cooper said on Thursday, asserting that the critical waterway remains accessible for commercial shipping despite ongoing tensions in the region. The statement, made without additional details on the specific corridor or operational terms, signals an effort by Washington to reassure markets and maintain the flow of oil through one of the world's most vital energy arteries.

Mixed Signals from Iran

The declaration comes days after Iranian officials signaled willingness to permit passage for non-hostile vessels, though they stopped short of guaranteeing unimpeded transit for US-linked or Israeli-linked ships. Tanker tracking data shows a growing number of carriers have opted to reroute via the Cape of Good Hope, adding voyage times and costs. "Without a clear and consistent framework, we're seeing a patchwork of insurance premiums and routing decisions," said a shipping executive familiar with the matter. Attempts to reach Iranian authorities for comment were unsuccessful.

Market Reactions

Oil prices edged lower on the news, with Brent crude slipping 0.8% to $82.40 a barrel, though traders remain wary of sudden disruptions. "The market is pricing in a risk premium that could evaporate if the passage holds, but any escalation could send prices sharply higher," said a senior energy analyst. The Hormuz chokepoint handles about 20% of global oil consumption, making its status a key focus for shippers and importers alike.

Naval Presence and Industry Impact

The US and allied forces have bolstered naval assets in the Persian Gulf over recent weeks, conducting patrols to deter any blockade attempts. Shipping firms have responded by adjusting schedules and building buffer stocks. Insurance underwriters have hiked war-risk premiums for voyages through the strait, with some quoting rates up to ten times normal levels. "We're advising clients to explore alternative routes if possible," said a marine insurance broker.

Looking Ahead

The situation remains fluid, with potential for both de-escalation and further confrontation. Industry observers will watch for any formal commitment from Iran to uphold free passage for all commercial traffic, which could restore normalcy. The coming days are critical, as any misstep could trigger a broader crisis in energy markets.
