The decision, described in an account of the Feds most recent policy-making meeting in June, signals the end of one of the central banks most aggressive efforts to stimulate the economy. The Fed, which started reducing its monthly purchases in January, said it planned to add a final $100 billion to its holdings of Treasuries and mortgage-backed securities over the next four months, for a total of $1.5 trillion.
But the account underscored that many Fed officials remained guarded in their optimism about the economy. It also suggested that they had not yet decided when to take an even more important step in their retreat: raising short-term interest rates for the first time since December 2008.
Investors generally expect the Fed to start raising interest rates next summer. The Fed said the decision to end bond purchases in October, rather than continuing purchases at a nominal level until the end of the year, should not be interpreted as evidence that rate increases were likely to begin sooner.
Fed officials disagree about the pace of retreat in large part because they disagree about how much more monetary policy can accomplish.
