Oil Hits 5-Day Rally as U.S. Vows “Unprecedented” Pressure on Iran

Oil prices climbed for a fifth straight session on Monday, extending a rally driven by Washington’s threat of new economic measures against Tehran. President Donald Trump said the United States would impose what he called “unprecedented economic isolation” on Iran, without specifying the exact steps or timing. The comment fueled supply concerns in a market already tight from OPEC cuts and sanctions on Venezuela. Traders now watch for any concrete action, as a full halt to Iranian exports could remove more than one million barrels per day from global markets. No new policy has been announced yet, and oil prices remain volatile on every headline.
