Haruhiko Kuroda's Legacy

The Bank of Japan (BOJ) aimed for a 2% inflation target in 2013, collaborating with Prime Minister Shinzo Abe. The BOJ implemented quantitative easing and later introduced yield curve control to spur inflation. Despite efforts, the target was not met, but inflation rose above 0%. By 2022, the BOJ became a major stockholder, and yen weakening boosted inflation to 4%. In 2023, the BOJ widened the yield band, sparking investor speculation about policy changes. The future of 'Corona Nomics' remains uncertain as new leadership takes over.
