BOJ’s 19-Dec-2025 0.75% Liftoff Ends Japan’s Zero-Rate Era

When the BOJ last tried to normalise—August 2000’s 0.25 % hike and July 2006’s move to 0.50 %—recessions quickly forced reversals; those false starts, alongside 2013’s unprecedented QQE, kept Japan the global fountain of free yen. Today’s lift, though still leaving real rates negative, closes the world’s final zero-rate chapter and chips away at a funding model that powered the carry trade and cushioned a public debt near 230 % of GDP. Structurally, it reflects three intertwined shifts: stubborn global inflation after the pandemic, tentative wage gains despite a shrinking labour force, and political tolerance for stronger yen to ease imported-price pain. Over a 100-year lens, this could mark the moment Japan exited its post-bubble deflationary epoch and re-joined the monetary mainstream—or, if growth falters, another entry in its long catalogue of premature tightenings, underscoring how demographic drag and fiscal overhang complicate any return to “normal” interest-rate terrain.
