Oil prices rose by more than 3% after retaliatory US strikes in the region and the return of crude oil sales sanctions on Iran. The move put fresh pressure on traders tracking supply through the Strait of Hormuz, where an Iranian attack on a liquefied natural gas tanker was reported before the strikes.
Trump, Iran and the 3% jump
At the NATO summit in Ankara, Donald Trump said the memorandum of understanding with Iran is over. He said, "I do not want to deal with them any more, they are scum" and added, "As far as I am concerned, it is over."
The scale of the move matters because the crude market is treating each new strike and sanction as another check on supply routes. When the US restores crude oil sales sanctions, it tightens the path for Iranian barrels to reach buyers and leaves more of the market pricing in disruption risk instead of just current supply.
Richard Hunter on Middle East risk
Richard Hunter, head of markets at interactive investor, said: "Sentiment was also negatively affected on what is becoming a ceasefire in the Middle East in name only." His line captures why the reaction moved beyond geopolitics and into pricing: traders were forced to weigh whether the latest strikes would stay isolated or keep feeding the same route through the Strait of Hormuz.
That friction was already visible in broader markets, where European stock markets were sliding and Wall Street had modest losses on Tuesday. Oil did not move in isolation; it rose into a session where risk appetite was already being trimmed by the same regional backdrop.
Sanctions tighten crude flows
The return of crude oil sales sanctions changes the practical route for Iran's exports. Buyers face a narrower channel to purchase barrels, and that can push any premium in the spot market higher when shipping lanes are already under stress.
How long the oil price rise lasts after the US strikes and renewed sanctions is the unresolved part. For now, the market is pricing the combination of military action, sanctions and a tanker attack as a direct threat to supply discipline rather than a one-day headline.
