WTI crude oil prices slipped to around $91.50 per barrel on Tuesday during European trading hours, ending a three-day streak of gains. This decline came despite ongoing geopolitical tensions, as increased Russian diesel exports helped ease supply concerns, according to FX Street.

The price drop highlights the balancing effect of Russian fuel shipments in global markets, which have offset some of the upward pressure on oil prices caused by geopolitical uncertainties. The reversal in WTI prices marks a notable pause after several days of steady increases.

For Japanese investors, the movement in WTI crude oil prices is significant given Japan's reliance on imported energy resources, influencing inflation expectations and equity market sentiment in the region.
