The dollar took its biggest tumble in almost two months on Thursday and stocks crept to nine-month highs as cautious sounds from the U.S. Federal Reserve left the focus firmly on Japan's next round of money-printing measures, Reuters reported. The dollar was down 0.7 percent against six other major currencies after the Fed ended its meeting on Wednesday with little suggestion that it was in a rush to raise U.S. interest rates. It had seen traders cut their bets on a September Fed move to just 17 percent. Benchmark 10-year U.S. government bond yields fell back to 1.5 percent though there was no follow-through in Europe where yields nudged higher. The yen, meanwhile, notched its fourth rise in six days as news that Tokyo had unveiled a surprisingly large 28 trillion yen ($265 billion) stimulus package left traders wondering how aggressive the Bank of Japan would be when it meets on Friday.
