The United States Dollar Index experienced notable volatility on Friday, fluctuating within a broad range as traders responded to escalating geopolitical tensions between the United States and Iran. This week saw renewed hostilities between the two nations, contributing to uncertainty in the FX markets.

According to FX Street, market participants remained cautious, closely monitoring developments in the Middle East. The sparse US economic calendar this week further limited directional momentum for the dollar, leaving the index to trade within a choppy environment.

For Japanese investors, these movements highlight the importance of geopolitical risk in influencing currency dynamics, especially as the yen remains sensitive to shifts in global risk sentiment and safe-haven flows.
