Brent crude oil prices have climbed above the US$100 mark, driven by escalating tensions between the US and Iran, alongside recent attacks by Houthi forces targeting shipping lanes in the Red Sea. These developments have heightened concerns over supply disruptions in a key global oil transit route.

According to FX Street, UOB Global Economics & Markets Research noted that Brent crude has surpassed US$100 for the first time since May, with prices in Asian markets trading close to US$101. The combination of geopolitical risks has contributed to this upward pressure on oil prices.

For Japanese investors, who are sensitive to energy price fluctuations due to the country's heavy reliance on imported oil, this rise could impact inflation expectations and influence market strategies in FX and equities.
