## Prediction

Over the next 24 hours, Brent crude prices and diesel crack spreads are likely to rise as traders price in Ukrainian claims of major Russian refining disruption and Iran’s shootdown of a recon drone over Hormuz. Concerns about Russian product exports and Gulf shipping risk will add a risk premium, particularly on diesel and fuel oil linked to disrupted Russian refineries. This movement will strain fuel‑importing economies in Europe and emerging markets, while boosting revenues for alternative suppliers. Confirmation would be a visible uptick in Brent and ICE gasoil futures, plus widening Urals and product differentials; denial would be flat or falling prices despite the news, implying skepticism about actual disruption.

## Drivers

- Ukrainian and Polish statements claiming 30–40% of Russian refining capacity temporarily destroyed or offline
- Massive drone strike on Moscow region including at least one key refinery
- Iran’s claim of shooting down an advanced drone over the Strait of Hormuz, heightening route risk
