Oil prices climbed for a fourth consecutive session on Tuesday, driven by mounting supply disruption risks in key producing regions. Brent futures rose 0.4% to $64.10 per barrel, while West Texas Intermediate crude gained to $59.70. Both benchmarks recently hit multi-week highs as traders factor a growing geopolitical premium into the market.

Heightened concerns center on Iran, where intensifying anti-government protests have sparked fears of a crackdown. U.S. President Donald Trump warned of possible military action and announced plans for a 25% tariff on any country trading with Tehran. This move specifically targets major buyers like China, though its effectiveness remains uncertain. Meanwhile, Trump also indicated that Venezuela could soon resume oil exports, potentially adding barrels back to the global supply.

Supply risks are not confined to the Middle East. Ukraine has repeatedly targeted Russian energy infrastructure, including the Caspian Pipeline Consortium terminal. Exports through this critical route are expected to drop sharply this month, further tightening the market.
