Greenback slips versus Euro and Yen before Fed

The U.S. Dollar weakened earlier on Wednesday trading session falling against the 17-nation bloc currency and the Japanese Yen as investors awaited a result from the Federal Reserve policy meeting possibly bringing less stimulus by the U.S. central bank. The so-called Greenback traded at $1.3772 earlier on Asian trading session and the U.S. Dollar Index stayed flat at 80.02, down from Monday's level of 80.419.
