The U.S. dollar took a hit on Friday after President Donald Trump called China and the European Union currency and interest rate manipulators in a tweet. Trump that "while the U.S. is raising rates while the dollars gets stronger and stronger with each passing day," China and the eurozone were robbing the U.S. of its "big competitive edge." The ICE U.S. Dollar Index DXY, +0.01% dropped 0.5% to 94.674, extending previous losses. The euro EURUSD, -0.04% , the greenback's main rival, rallied to a three-day high of $1.1709 in response. China's yuan was more timid in response. The offshore-traded yuan USDCNH, +0.00% strengthened slightly, with one dollar buying 6.7882 yuan, while the more restricted onshore yuan USDCNY, -0.15% remained marginally weaker, as one dollar fetched 6.7705 yuan.
