The US Dollar Index struggled to maintain momentum above the key 100.00 level during the Asian session on Thursday, edging lower as expectations for further Federal Reserve interest rate hikes diminished. This stall reflects cautious sentiment among traders regarding the US central bank's next moves.

According to FX Street, the index continues to face resistance around this psychological threshold, indicating uncertainty in the currency market. The Federal Reserve's stance on monetary policy remains a critical driver for the US Dollar's direction in the near term.

For Japanese investors, this development is notable as fluctuations in the US Dollar Index can influence cross-currency rates and impact FX trading strategies in the region.
