The Federal Reserve is widely expected to leave interest rates unchanged at its meeting on Wednesday. Treasury yields have fallen sharply following weak jobs data and comments from Janet Yellen suggesting a June rate hike is unlikely. The Fed's dot plot projections and Yellen's press conference will be closely watched for signals about the path of rates. Elsewhere, the Bank of Japan, Swiss National Bank, and Bank of England also announce monetary policy decisions this week. Brexit fears and inflation data will also influence currency and equity markets.
