The US Dollar Index saw a cautious rebound at the start of the week, holding just below the 100 level. This move coincided with a market environment marked by defensive equities and firmer US Treasury yields, reflecting investor caution.

According to FX Street, the US Dollar showed modest strength as equities remained defensive and Treasury prices firmed. Scotiabank also noted that the Dollar Index was capped near 100 during this careful rebound, indicating limited upside momentum.

For Japanese investors, this cautious dollar strength may influence FX trading strategies, especially given the ongoing sensitivity of Japanese markets to US monetary signals and Treasury movements.
