Oil Prices Post Biggest Gain Since 2020 as Middle East War Fears Reignite

Oil prices experienced their most significant surge since 2020, with WTI crude jumping 9.4% to $78.14 a barrel and Brent crude rising 9.6% to $83.30. This dramatic increase followed weeks of subdued pricing, as market participants had begun to hope for a de-escalation of the conflict in the Middle East. The renewed spike in prices was directly linked to a threat by U.S. President Trump to blockade the Strait of Hormuz, a critical chokepoint for global oil transport.

The geopolitical tensions surrounding the Strait of Hormuz have historically been a major driver of oil price volatility. Trump's assertive stance has reignited concerns about potential supply disruptions, prompting a swift reaction from the market. Brent futures saw their largest single-day dollar gain since April 2, settling at their highest point since June 12, while U.S. crude futures recorded their largest daily gain since April 29, closing at their highest level since June 15.

Beyond the oil markets, the heightened tensions also impacted currency exchange rates. The Australian dollar experienced a notable decline, dipping below 70 US cents. Analysts at CBA attributed this weakening to renewed concerns about energy supply disruptions in the Strait of Hormuz, which weighed on overall risk sentiment and supported the U.S. dollar. They noted that the AUD/USD pair dropped towards 0.6910 and could potentially fall further to support at 0.6847 if the situation escalates. Upcoming U.S. inflation data was also cited as a potential factor influencing the Australian dollar's performance.
