Brent crude oil prices plunged 4.4% at the open following news that the United States and Iran have agreed to prolong their pause in hostilities. This development eased immediate fears of supply disruptions along the Strait of Hormuz, a critical passage for global oil shipments.

Before this drop, Brent was trading near the $100 mark, fueled by ongoing geopolitical tensions in the Middle East. The extension of the ceasefire suggests calmer waters ahead for the oil market, with traders now discounting the risk of sudden interruptions in crude flow. Market sentiment shifted quickly, reflecting a growing perception that the threat of conflict-driven supply shocks has diminished for the time being.

Currently, the odds of Brent hitting a new all-time high by the end of September have fallen to 6.2%, indicating that the recent developments have tempered bullish speculation. Analysts and investors remain alert to any shifts in the US-Iran dynamic or changes in OPEC's production strategy that could reverse this trend.

Staying on top of updates from energy watchdogs and geopolitical news will be essential as the market watches for factors that might reignite volatility or impact global demand forecasts. Meanwhile, recent moves in oil prices contrast with gains seen in other markets such as US stocks and the Australian dollar, marking a notable divergence in asset performance.
