The language does for the first time however link its $120 billion in monthly purchases of US Treasury bonds and government-backed securities to a set of economic conditions. It had previously pledged to make those purchases only "over coming months," with no firm guidance about when the recession-fighting program might stop.
"We had expected perhaps an extension of the maturities of the asset purchases. They didn't do that," said Kathy Bostjancic, chief US financial economist at Oxford Economics.
"But this guidance, forward guidance on QE (quantitative easing) is pretty powerful ... that gives some clarity, which is good." US stocks, up slightly ahead of the Fed's statement, pared their gains and were mixed in mid-afternoon trading. Benchmark US Treasury security yields ticked higher, and the dollar edged up against major trading partner currencies.
