"Inflation was running below the Committee's longer-run objective, and this was seen as posing possible risks to economic performance," the minutes said. "Many members saw a need for the Committee to monitor inflation developments carefully for evidence that inflation was moving back toward its longer-run objective."
Others also expressed concern about indicators of persistent labor-market weakness, including low workforce participation.
"Many members judged that the Committee should proceed cautiously in taking its first action to reduce the pace of asset purchases and should indicate that further reductions would be undertaken in measured steps," the minutes said.
The minutes stressed that the Fed's bond buys and low-rates policies are contingent not just on the economic backdrop but also based on officials' assessment of their costs and efficacy. One risk is that low rates will lead to asset bubbles, though the central bank did not appear greatly concerned about such a possibility for now.
"Indicators generally suggested that such risks were moderate, in part because of the reduction in leverage and maturity transformation that has occurred in the financial sector since the onset of the financial crisis."
