Reporters ask Federal Reserve Chairman Ben Bernanke questions during a press conference following the Federal Open Market Committee meeting at the Federal Reserve Bank headquarters on December 12, 2012 in Washington, D.C. - 

The Federal Reserve recently released the minutes from its mid-December meeting in which it announced a major shift in approach: Vowing to continue an expansionary monetary policy until unemployment hits 6.5 percent

But support for such a policy is apparently not unanimous.

"The Fed was talking about easing and buying treasuries, but now it seems that there is a significant segment of the Fed that say, 'Hey, maybe by the end of the year, we are going to stop buying treasuries,'" says John Silvia, chief economist at Wells Fargo.

Silvia says the newly revealed details will have an immediate effect on the market, as expectations about the Fed's stimulus program shift.

"5, 7, 10 year treasury rates will go up -- and they indeed have," says Silvia.
