NATO Secretary General Jens Stoltenberg will become Norway's new central bank chief, the government said on Friday, despite opposition worries that the appointment of the former prime minister could weaken Norges Bank's independence.
While the job is open from March 1, Stoltenberg has said he would first serve out his term at NATO, which runs until September 30.
Norges Bank separately said it expects the new governor to take over on or around December 1 this year.
Stoltenberg will be in charge of setting interest rates and managing financial stability as well as overseeing Norway's sovereign wealth fund, the world's largest with assets of $1.4 trillion.
"I've been concerned with identifying the best central bank governor for Norway, and I'm convinced that this is Jens Stoltenberg," Finance Minister Trygve Slagsvold Vedum said in a statement.
The appointment ends any speculation that Stoltenberg would stay on at NATO, and the search for a successor must thus now begin in earnest ahead of a meeting of member nation leaders in June this year.
The alliance has been a focus of current tensions between Russia and the West over Ukraine, with Moscow massing troops on its border and seeking assurances that NATO will never admit Ukraine as a member.
Stoltenberg, an economist by training and former leader of the Labour Party, was Norwegian prime minister from 2000-01 and 2005-13 before becoming NATO chief the following year.
He has also been finance minister and energy minister.
Ida Wolden Bache, deputy chief of the central bank and Stoltenberg's main rival for the job, will be the acting governor until Stoltenberg takes over, the government said.
Stoltenberg's application set off a debate in Norway as to whether he was the candidate best suited for the position.
His supporters say he has decades of leadership experience and the political heft to helm the bank, drawing parallels to the 2019 appointment of French lawyer, politician and IMF chief Christine Lagarde as president of the European Central Bank.
They cite Stoltenberg's role as the man behind the self-imposed rule by which Norwegian governments only spend a small portion of the value of the wealth fund each year for national budgets.
His detractors say his appointment raises questions about the bank's independence from the government, since Stoltenberg's party currently rules Norway in coalition with the agrarian Centre Party.
He is a friend of the current prime minister, Jonas Gahr Stoere, who recused himself from the hiring process because of the conflict of interest.
Former finance minister Siv Jensen, in office from 2013 to 2020, last month urged Stoltenberg to withdraw from the process, arguing his appointment would damage the central bank's credibility and reputation.
"With Stoltenberg as governor there will be strong doubt regarding Norges Bank's independence," Jensen of the right-wing Progress Party wrote in a column in business daily Dagens Naeringsliv.
The deputy head of Norway's main opposition Conservative Party, Tina Bru, had also argued against Stoltenberg's candidacy, calling it unwise to appoint him.
