The dollar edged higher against major currencies in the New York foreign exchange market, driven by escalating tensions between the United States and Iran and hawkish comments from Federal Reserve officials. The dollar rose 0.46 percent against the yen to 162.43 yen, hovering near a roughly 40-year low and reigniting intervention concerns. President Trump announced the reimposition of a maritime blockade on Iran and a 20 percent levy on cargo passing through the Strait of Hormuz, with risk-averse flows supporting dollar buying. The market is now focused on the US CPI data on the 14th and the Fed chair's congressional testimony.
