The Japanese government on Tuesday nominated Waseda University political science and economics professor Junko Koeda to join the Bank of Japan's nine-member board.
The nomination comes at a critical time for the BOJ, which last week raised interest rates to their highest since the 2008 global financial crisis on the view Japan was on the cusp of sustainably achieving its 2% inflation target.
Koeda, who specialises in macroeconomics and finance, previously held positions as a chief economist at the Japanese finance ministry and a staff economist at the International Monetary Fund. She has a Ph.D. degree in economics from UCLA.
Koeda was a member of a BOJ workshop in December 2023 that debated the pros and cons of past unconventional monetary policy.
In a newspaper commentary in April last year, soon after the BOJ ended eight years of negative interest rates and its bond yield control, she described the move as a historic step at the right timing. She also called for fiscal reform to ease upward rate pressure on the government bond market.
"Her appointment probably meshes with Governor Ueda's hope to deepen the bank's theoretical understanding on its monetary policy," said Mari Iwashita, a veteran BOJ watcher who is currently executive economist at Daiwa Securities.
"It will likely help deepen the BOJ's internal debate on where Japan's neutral rate lies," Iwashita said, referring to financial markets' focus on how much higher the bank could push borrowing costs without dragging on economic growth.
Koeda would replace former economist Seiji Adachi, whose five-year term ends on March 25.
Adachi has been considered as taking a neutral approach on monetary policy and voted for the BOJ's decisions throughout his term.
Takahide Kiuchi, a former BOJ board member who is currently an economist at Nomura Research Institute, described Koeda as a scholar with a proven track record in quantitative analysis of the BOJ's monetary policy.
"She pointed out the side effects of the BOJ's monetary easing in the past, giving an impression that she has a neutral stance on policies," Kiuchi said.
Prime Minister Shigeru Ishiba's first pick of a new BOJ board member has been closely watched by markets as offering clues on the administration's stance on monetary policy.
The nomination must be approved by both houses of parliament. Ishiba's minority government will need endorsement from opposition parties to get the nomination approved.
