This morning at 10:00 a.m EST in Washington DC, Janet Yellen, Federal Reserve Chairperson-Designate, testified on monetary policy before the Senate Banking Committee. Unexpectedly, text of the testimony was released 17 hours earlier than the scheduled speaking time. Today’s testimony had a positive effect on currency. The testimony is normally given in two parts. First, the prepared statement is read and a text version is made available on the Fed’s website. The second part is a Q&A session, where the questions are not known beforehand. The questions, being unscripted, can lead to some moments of heavy market volatility, as traders try to predict the effect on the bank’s monetary policy.
