FOREX-Dollar edges up ahead of inflation reading, euro awaits ECB decision

The dollar edged up ahead of the key U.S. inflation report due later on Wednesday, while the euro fell from a one-week high in the previous session with traders cautious ahead of an expected European Central Bank rate hike on Thursday. The dollar index, which tracks the currency against six peers including yen, euro and sterling, held firm, though moves were subdued, up 0.1% to 104.70, as traders awaited the U.S. consumer price index (CPI) reading for August. The release comes just a week before Federal Reserve officials gather to decide on interest rate policy.
