STOCKHOLM, Jan 21 (Reuters) - Sweden's central bank said on Friday its first deputy governor, seen as a hawk, will step down at the end of 2011 when his term expires, adding to uncertainty over monetary policy after the turn of the year.
The bank said First Deputy Governor Svante Oberg, widely seen as one of the most hawkish members of the Riksbank's six-member executive board, had notified the bank he will not stand for re-election to the body and would leave the bank.
The turn of the year will bring more changes to the Riksbank as Deputy Governor Lars Nyberg has also said he will step down then as his term expires.
Governor Stefan Ingves' first term expires at the same time, although he has not said whether he will stand for a second one.
With Sweden weathering the financial crisis better than most, the Riksbank embarked in July on a gradual tightening of monetary policy to cap inflation, and forecasts further rate hikes. But the board has been split in all four decisions to raise.
"There will be a degree of uncertainty now that at least two new board members are going to be appointed next year," SEB economist Elisabet Kopelman said.
"Given that we have a board that is already split, it creates uncertainty about the direction of policy after this year," she said.
Kopelman said the resignation of Oberg, a member of the Riksbank's executive board since January 2006 and close to retirement age, was expected. It would be a bigger surprise if Ingves opted not to stay for a second term, she said.
"We will announce the appointment of three members later in the year," Chairman of the General Council Johan Gernandt and Vice Chairman Leif Pagrotsky said in a statement.
