The big number markets are waiting for is the November employment report due on December 4, after October's report of 271,000 nonfarm payrolls and a surprise pickup in wages. That report will have direct bearing on the Fed's rates decision on December 16.
"The Fed was already promoting the idea of a December rate hike well ahead of that very strong October payroll report, thus the odds that lift-off begins at the upcoming meeting are extremely elevated. We noted weeks ago that the largest precondition to tighten in December would be the ability to get the market to 'buy in' to the idea of a hike," said chief U.S. economist at RBC Capital Markets, Tom Porcelli.
"With market odds now sitting at roughly 75 percent that they go, it looks as though the committee has done its job from a communications standpoint," Porcelli added.
