Sept 21 (Reuters) - U.S. stocks pulled back from their all-time highs on Thursday as investors assessed the Federal Reserve’s policy statement, which hinted at raising interest rates for the third time this year and laid out plans to roll back its monetary stimulus.
The Fed said it would begin to reduce its approximately $4.2 trillion in holdings of U.S. Treasury bonds and mortgage-backed securities - acquired in the years after the 2008 financial crisis - from October.
While the central bank left rates unchanged, it cited low unemployment, growth in business investment and an economic expansion that has been moderate but durable this year to build its case for another rate hike in 2017.
Interest rate futures are now pricing in about a 70 percent chance of a December hike, according to CME’s FedWatch tool, up from above 50 percent prior to the Fed meeting.
Fed Chair Janet Yellen said the fall in inflation this year remained a mystery, adding that the central bank was ready to change the interest rate outlook if needed.
“The hint of a rate hike in December was no surprise to us and we reiterate our stand, that it is not likely to unravel the market’s bullish posture in anticipation of tax cuts,” said Peter Cardillo, chief market economist at First Standard Financial.
