WTI crude oil prices remained largely unchanged on Friday, trading around $90.65 per barrel, a slight increase of 0.10% on the day, according to FX Street. Market participants are closely monitoring geopolitical tensions between the US and Iran, which continue to weigh on supply concerns in the critical Strait of Hormuz region.

The Strait of Hormuz is a vital chokepoint for global oil shipments, and any disruption there could significantly impact crude supplies. Traders are balancing these risks with other market factors, resulting in the steady price movement observed.

For Japanese investors, who are sensitive to fluctuations in energy prices due to the country's heavy reliance on oil imports, the stability in WTI pricing offers a moment of relative calm amid ongoing geopolitical uncertainties.
