FXstreet.com (Barcelona) - The Federal Open Market Committee (FOMC) has come as a slight shocker, after some members were divided over how long asset purchases should last.

From the minutes: "A few members thought asset purchases would likely be warranted until the end of 2013, while several others thought that purchases were likely to slow or stop well before the end of 2013".

Nomura economist Ellen Zentner notes: "A few others expressed the need to maintain considerable policy accommodation, but declined to speculate on how long purchases would last." Nomura expects the FOMC "to continue its long-term asset purchases through the end of the third quarter of 2013" Ellen adds.
