The US Dollar Index (DXY) is gradually climbing and is currently hovering near the 98.90 mark, according to FX Street. This movement comes ahead of the release of global flash Purchasing Managers' Index (PMI) data scheduled for Thursday.

Despite this upward trend, the index remains below the significant 100.00 level, which market participants closely watch as a psychological barrier. The Federal Reserve Bank of St. Louis continues to provide insight into the broader economic environment influencing dollar strength.

For Japanese investors, the dollar's steady rise ahead of key economic indicators could impact FX and equity markets, especially given the yen's sensitivity to US dollar fluctuations in times of global economic uncertainty.
