West Texas Intermediate (WTI) crude oil prices fell below the $100 mark on Wednesday amid Saudi Arabia's intensified efforts to restore oil flow through its East-West pipeline. The pipeline had been damaged by a drone attack last week, disrupting supply routes.

According to FX Street, the decline in WTI prices reflects market optimism that Saudi Arabia's repair work will soon resume normal operations, easing supply concerns. The pipeline is a crucial artery for the kingdom's oil exports, and its swift restoration is closely watched by global markets.

For Japanese investors, who are highly sensitive to energy price fluctuations due to the country's heavy reliance on imported oil, developments in Middle Eastern supply chains remain a key factor influencing FX and equity market movements.
