Hans Nilsson, FX strategist at CMS Forex- "The dollar, trading mixed against its rivals Wednesday, was sharply higher against the commodity currencies but lower versus the yen and euro. In an unprecedented move to alleviate the financial crisis and global economic slowdown, major six central banks each cut benchmark interest rates 50 basis points. Sterling fell after the UK government announced a package of new measures to help the banking system which could total £400 billion ($692 billion). The yen gained as risk aversion increased and the coordinated rate cuts failed to cheer stock markets. The Australian dollar plunged the most since 1983."
