The dollar extended losses against the euro on Tuesday as the market awaited the outcome of a U.S. Federal Reserve policy meeting on Wednesday and a record $104 billion in U.S. debt issuance this week.

Ben Bernanke’s testimony yesterday in front of congress is being taken by Wall Street as a signal that the Fed is prepared to continue to lower interest rates.

According to Bloomberg, traders now see a one-in-five chance of a half-point reduction in the benchmark rate, to 1.75 percent, at the April 29-30 Fed meeting.

Bernanke told congress yesterday that the Fed is “ready to respond to whatever situation evolves,” and referred to “considerable stress” in markets.
