The U.S. dollar strengthens to its highest level in more than a year as investors price in further Federal Reserve rate hikes and seek safety amid market volatility. The dollar index, which tracks the greenback against a basket of currencies including the euro and the yen, rises to around 101.44, its strongest level since mid-May 2025. Multiple reports link the move to a broader risk-off environment following a tech stock sell-off, which drives demand for the dollar as a relative safe haven. At the same time, expectations for additional U.S. policy tightening are cited as a key driver. Markets are increasingly pricing a higher likelihood of interest rate increases in July and September, which supports the dollar against major counterparts such as the euro and the yen. Overall, both the safe-haven flows from equity weakness and the shift in rate expectations contribute to the dollar’s rise to a 13-month high.
