Tensions Flare in Strait of Hormuz as US Revokes Iran Oil Export License

A brief calm in the oil market ended within a day following the US cancellation of its permit for Iranian oil sales, a series of American strikes in Iran, attacks on commercial ships in the Strait of Hormuz, and President Donald Trump's declaration at the NATO summit in Ankara that the ceasefire is over. This sequence has plunged the market into high uncertainty, with expectations for cautious developments in the coming days as both the US and Iran could escalate or negotiate. Qatar, Oman, and Pakistan remain mediators aiming to prevent a complete breakdown of the understanding.

Currently, about 63 million barrels of Iranian oil are floating at sea or awaiting clear destinations, representing potential revenues of approximately $4.7 billion at $70-75 per barrel. However, these shipments face operational and legal challenges due to the revoked US license, with banks reluctant to handle funds, insurers refusing coverage, and ports wary of sanctions exposure. The US Treasury's move has had a more immediate market impact than military threats, abruptly ending a two-month window for Iranian oil exports that began with a June 22 permit.

Oil prices reacted sharply: Brent crude rose from around $71.94 to $78 per barrel, and WTI from $68.78 to $74, marking a two-week high even before any direct disruption of crude flow through Hormuz. Investors are pricing in risks of increased military conflict, rising maritime insurance costs, and potential blockade of this critical shipping route. The US Central Command reported strikes on over 80 Iranian targets in retaliation for attacks on three commercial vessels, raising the stakes further as Iran threatens to target any US military support.

Looking ahead, July 17 is a critical deadline when buyers must finalize purchases under the revoked license. Two scenarios are possible: mediators could broker a limited return to export licenses and safe passage commitments, allowing Trump to claim pressure yielded results; or escalating retaliations could continue, increasing the risk of a full naval blockade. While all parties have incentives to avoid prolonged conflict, recent volatility shows that market logic may not align with on-the-ground realities.

In the near term, the market will monitor four key indicators: any clarifications or revised licenses from the US Treasury, movements of Iranian tankers, the scale of maritime attacks, and announcements of urgent mediation talks before July 17. Until then, Iranian barrels will trade at steep discounts and all oil prices will carry heightened risk premiums due to the fragile geopolitical environment.
