Whatever Federal Reserve Chairman Ben Bernanke says Wednesday afternoon threatens to rock some part of the financial markets.
"That's how I see it. Tomorrow is dangerous," said Art Cashin, director of NYSE floor operations at UBS.
Financial markets always watch the Fed, and they always hang on every word of Fed policy. But the Fed's post-meeting statement or comments from the Fed chairman Wednesday will either give credence to or conflict with a recent fundamental shift in market perception – and that is that there will be a slow creep to higher rates as the Fed slows and then ultimately ends its bond purchase program.
