The U.S. dollar weakens, with softening market expectations regarding potential Federal Reserve interest-rate hikes. "It [the dollar] remains on track to end the week in negative territory following Thursday's disappointing jobs report," DHF Capital's Bas Kooijman says in a note. Looking ahead, traders will turn to next week's ISM Services PMI, FOMC minutes and weekly jobless claims for further clues on the Fed's monetary policy path, the CEO and asset manager says. Developments in U.S.-Iran talks will also be monitored, as progress could ease safe-haven demand and add further pressure on the dollar, while any setbacks could support it, he says. The DXY dollar index falls 0.1% to 100.748. (emese.bartha@wsj.com)
