Tuesday's meeting of the central bank's rate-setting Federal Open Market Committee did little to give equities direction after an initial mid-afternoon pop. They key difference in the FOMC's latest policy statement was in regard to falling asset prices, which the central bank could bolster by buying up more long-dated Treasurys in a second round of so-called quantitative easing.
"Measures of underlying inflation are currently at levels somewhat below those the Committee judges most consistent, over the longer run, with its mandate to promote maximum employment and price stability," the Fed's statement said.
The central bank kept its fed funds target range of 0% to 0.25% unchanged for the 20th straight month, and it maintained the same stance regarding future interest rate policy, reiterating that it will keep rates "exceptionally low" for an "extended period." Two-thirds of economists polled by Bloomberg said they believe the Fed will move to boost the economy through quantitative easing by the end of the year.
The bond market got a lift Tuesday as the yield on the benchmark 10-Year Treasury note fell to 2.59% from 2.67%. (Bond prices and yields move in opposite direction.)
