**Summary**: US Treasury will not renew waivers that allowed sales of Russian and Iranian oil already at sea, removing a key workaround introduced during recent disruptions. This tightens de facto sanctions enforcement and raises uncertainty over the disposition and pricing of those barrels, adding upside pressure to crude benchmarks and relevant spreads.

## Detail

The US Treasury has confirmed it will not renew temporary waivers that permitted the sale of Russian and Iranian oil already at sea. These exemptions were introduced as a flexibility tool during recent energy market disruptions, effectively allowing some volumes to clear despite tightening sanctions regimes. Their expiry signals a deliberate US move to re‑harden enforcement around Russian and Iranian crude and condensate trade, particularly for cargoes in transit relying on opaque shipping, financing, and insurance arrangements.

Supply-side impact is twofold. First, any Russian or Iranian cargoes currently afloat under these waivers face greater difficulty in discharging, which can lead to (a) forced discounts to risk-tolerant buyers, (b) off-radar ship-to-ship operations, or (c) effective shut-in if logistical and insurance constraints bite. While precise volumes are not disclosed, even a modest disruption or delay of several hundred thousand barrels per day of marginal barrels can significantly influence prompt spreads in a tight market. Second, the move will chill future contracting behavior, as traders and refiners reassess sanctions risk for spot and near-term Russian and Iranian loadings, potentially reducing effective export availability relative to nominal production.

Market-wise, this action tends to support Brent and WTI flat prices and widen the Brent–Dubai and Urals–Brent differentials, along with strengthening Mediterranean and Middle Eastern sour grades as substitutes. Indian and Chinese refining margins and procurement strategies may need to adjust if delivered risks and logistics costs for discounted Russian and Iranian crude rise. Tanker markets, especially Aframax and Suezmax segments serving the shadow fleet, could see higher risk premia, while mainstream, insured tonnage may benefit from cargo reallocation.

Historically, incremental sanctions enforcement steps on Iran (2012, 2018) and Russia (2022) have produced >1% moves in crude benchmarks as traders price in either actual or perceived supply loss. The impact here is likely front-loaded in prompt months and time spreads, with a risk premium component persisting as long as enforcement remains strict and geopolitical tensions with Iran and Russia stay elevated. Overall, this is a material, though not extreme, bullish factor for crude and some refined products over the coming weeks.
