**Summary**: The U.S. Treasury states Iran exported zero barrels in the last two weeks while U.S.-escorted flows through Hormuz totaled 130 million barrels. This signals an effective shutdown of Iranian exports despite restored transit through the strait, tightening medium-sour crude supply and elevating geopolitical risk premium in oil markets.

## Detail

U.S. Treasury Secretary Scott Bassant reports that over the past two weeks the U.S. has escorted 130 million barrels of oil through the Strait of Hormuz, during which time Iran exported zero barrels. This implies that, even though the physical chokepoint is open and being secured by the U.S. Navy, Iranian-origin crude has effectively been excluded from seaborne trade in the near term.

Before this disruption, estimates of Iranian exports were in the 1.5–2.0 mb/d range, largely to China and some smaller Asian buyers, often at a discount. A swing from ~1.5 mb/d to zero, even if partly offset by redirected flows from other Gulf producers under U.S. escort, is a meaningful negative supply shock in the medium-sour segment. Physical markets will feel this most acutely in Asia, where refiners optimized for Iranian grades will need to source alternative barrels (Iraqi Basrah, Saudi, UAE, Russian ESPO/Urals via re-routing), likely at higher differentials.

Immediate market impact should be a higher risk premium on Brent and Dubai benchmarks, steepening backwardation and widening spreads between sour and sweet grades. Brent and Dubai crude futures are biased higher; cracks for middle distillates (diesel/jet) may firm as refiners adjust slates and yields. Time spreads on key benchmarks and regional sour crude OSPs are likely to react more violently than flat price alone.

Currency-wise, the IRR remains structurally pressured; news of zero exports reinforces expectations of tighter FX inflows and could trigger further depreciation in the parallel market and increase default/risk premia on any Iranian-linked credit. If sustained, this disruption could also support competing exporters’ fiscal and currency positions (e.g., GCC producers, Russia).

Historically, sharp constraints on Iranian exports in 2012–2013 and the tightening phase of U.S. sanctions under the Trump administration both coincided with several-dollar risk premia on Brent, although offset by OPEC+ and U.S. shale responses. The duration of the current impact hinges on whether this is a transient enforcement spike or a new enforcement baseline. For now, the market should treat it as a multi-week to multi-month bullish factor for crude until clear evidence emerges that Iranian flows have resumed via alternative routes or sanction leakage.
