Why the Bank of Japan’s Tightening Cycle May Stretch Into 2028
Japan’s shift away from decades of ultra-easy monetary policy is far from complete, and the most difficult phase may still lie ahead.
While the Bank of Japan has already taken historic steps to lift rates off the floor, the next moves are expected to be slower, more political, and increasingly sensitive to global conditions.
Key Takeaways
- The Bank of Japan is expected to continue raising rates gradually toward a level close to neutral before 2028.
- Future hikes are likely to be spaced out and highly dependent on global growth and domestic inflation trends.
- Political pressure and fiscal policy could limit how fast the BOJ tightens monetary conditions.
Former BOJ board member Makoto Sakurai believes the central bank is quietly working toward a policy rate around 1.5% before Governor Kazuo Ueda’s term ends in 2028. That path, however, is unlikely to be smooth or pre-announced.
A cautious roadmap takes shape
Rather than signaling an aggressive tightening cycle, policymakers appear focused on incremental adjustments. Internally, the BOJ is thought to view rates near 1.75% as roughly neutral – high enough to avoid overstimulating the economy, but not restrictive. Staying below that threshold gives officials flexibility if growth weakens.
Under this approach, rate increases would likely come at long intervals, potentially spaced six months apart. A move toward 1.0% could emerge once confidence builds that both global demand and domestic wage growth remain resilient. Beyond that, each additional hike becomes more controversial, not because inflation has disappeared, but because higher borrowing costs carry broader consequences.
Global forces matter more than ever
Japan’s rate outlook is now tightly linked to developments abroad. Strong U.S. growth would help justify further normalization by supporting exports and corporate profits. A softer international backdrop, on the other hand, would strengthen arguments for patience.
At home, inflation remains above the BOJ’s long-standing 2% target, supported by higher wages and persistent cost pressures. Surveys show businesses expect this trend to persist over several years, reinforcing the view that inflation is no longer purely transitory. Still, policymakers are wary of acting too quickly and risking a reversal in fragile domestic demand.
Politics complicate the exit from easy money
Economic data is only part of the equation. As rates climb closer to neutral territory, resistance from within the political sphere is expected to grow. Prime Minister Sanae Takaichi’s government has favored fiscal support to cushion households from rising living costs, a stance that can clash with tighter monetary policy.
This tension may explain why BOJ communication under Ueda has often been deliberately non-committal. By avoiding firm forward guidance, the central bank preserves room to maneuver while gauging how much political backing exists for continued tightening.
Markets remain skeptical
Despite recent rate increases, investors have been slow to price in an aggressive path ahead. The yen’s weakness suggests markets remain unconvinced that Japan will keep pace with global tightening cycles, particularly if fiscal spending expands further.
Bond markets also reflect this uncertainty. While rates have moved higher, concerns about long-term fiscal sustainability and inflation risks tied to government stimulus continue to influence investor behavior more than monetary policy alone.
A long transition, not a sudden shift
Under Bank of Japan leadership, Japan has already closed the chapter on emergency-level stimulus. What follows is a prolonged transition rather than a clean break. If Sakurai’s assessment holds, the BOJ will continue nudging rates higher – but only when economic, political, and global conditions align.
The journey toward “normal” interest rates in Japan may take years, not quarters, and each step forward is likely to be measured, contested, and carefully framed.
