Brent crude for October delivery surged 3.83% to $82.49 a barrel on Thursday, snapping a recent downward trend as market sentiment shifted sharply.

The rally was fueled by mounting doubts among investors regarding the likelihood of a diplomatic breakthrough between the United States and Iran that could stabilize supply routes in the Middle East.

The price move marks a significant reversal from earlier sessions, where traders had been pricing in potential de-escalation.

As optimism over a US-Iran accord waned, the risk premium embedded in oil prices reasserted itself, pushing benchmarks higher.

This development underscores the market's sensitivity to geopolitical headlines, with traders quickly adjusting positions based on the perceived probability of a diplomatic resolution.

This volatility follows a period of mixed signals in the region.
