The Federal Reserve will keep buying bonds indefinitely to try to keep long-term borrowing costs low. It's just not clear how long indefinitely will be.
Minutes of the Fed's last policy meeting show that officials were divided about when to halt the purchases.
Some of the 12 voting members thought the bond purchases would be needed through 2013. Others felt they should be slowed or stopped altogether before year's end. This group worries that the bond buying is keeping rates so low for so long that it could ignite inflation or encourage speculative buying of risky assets.
