Oil prices fell sharply for a second straight day this week as traders grew more optimistic that the US and Iran could return to talks aimed at ending the war. The drop extended a volatile stretch in energy markets, with investors quickly reassessing the risk premium that had built up during the fighting.

According to the report, the move lower came as a pause in hostilities continued to hold. That helped calm immediate concerns about further escalation and reduced some of the market’s fear that conflict could keep putting pressure on crude prices.

Brent crude was among the benchmarks sliding as sentiment shifted. When markets see a better chance of diplomacy and a lower chance of disruption tied to conflict, oil prices often retreat because traders expect fewer near-term threats to supply and shipping conditions.

Even so, the latest swing highlights how sensitive the oil market remains to geopolitical developments. For now, renewed hopes for US-Iran negotiations and a sustained lull in the fighting appear to be driving the sharp pullback in crude.
