The US dollar gained value following a resurgence of attacks in the Middle East and the subsequent closure of the Strait of Hormuz, a critical chokepoint for global oil shipments. These developments have heightened geopolitical risks, prompting investors to seek the relative safety of the dollar.

According to Investing.com Forex, the dollar's rise reflects market reactions to the escalating conflict and disruptions in one of the world's most important maritime routes. The closure of the Strait of Hormuz has raised concerns over potential supply constraints, further supporting demand for the US currency.

For Japanese investors, these events underscore the importance of monitoring geopolitical factors that can influence FX markets, particularly given Japan's reliance on energy imports and its active participation in global trade.
