CMC Markets - The stronger than expected 140K release (exp 40K) of the December ADP survey on private payrolls should make today's interest rate decision a contentious one especially after Q4 GDP slumped to 0.6% (exp 1.2%) following 4.9% in Q3. Considering the ADP survey's correct signaling of the direction of the December payrolls report, today's figures should add to the surprise element of the Fed's decision, and increase the volatile reaction to the decision.
