The Bank of Japan (BoJ) has moved another step away from the ultra‑easy monetary policy that defined its stance for more than a decade. At its December 2025 meeting, the BoJ raised its key short‑term interest rate to 0.75%, the highest level since 2008, underscoring a gradual normalization of policy as inflation proves more persistent and growth stabilizes.[1]
From Negative Rates to 0.75%: A Slow but Historic Shift
For years, Japan was synonymous with ultra‑low and even negative interest rates. The BoJ held short‑term rates below zero and capped long‑term bond yields in an effort to fight deflation and spur growth. That regime began to change in 2024 and 2025 as inflation finally moved closer to the bank’s 2% target and wage dynamics improved.
By late 2025, the BoJ had already lifted its benchmark short‑term rate to 0.5%, where it remained at the October meeting.[1] At that time, the Policy Board voted 7–2 to keep rates unchanged, with two members arguing for an immediate hike to 0.75%—a clear sign of growing pressure to tighten.[1]
The December decision to take the policy rate to 0.75% therefore represents less a sudden pivot and more the continuation of a carefully signaled path toward normalization.[1] Relative to other major central banks, the BoJ is still highly accommodative, but the direction of travel has shifted decisively away from emergency‑era settings.
Why the BoJ Raised Rates Again
Three main factors underpin the latest rate increase: inflation dynamics, growth prospects, and global monetary conditions.
1. Inflation staying near target
In its October 2025 Outlook Report, the BoJ projected core inflation around 2.7% for fiscal year 2025, easing to 1.8% in FY 2026 before edging back up to about 2.0% in FY 2027.[1] Those forecasts imply that price stability, as defined by the 2% target, is increasingly within reach on a sustainable basis.
Governor Kazuo Ueda has repeatedly emphasized that the BoJ will consider further rate increases if the economy follows this projected path for inflation and growth.[1] The December hike is consistent with that conditional guidance.
2. Modest but improving growth
The BoJ also modestly upgraded its growth outlook for FY 2025, revising GDP growth to 0.7% from a previous 0.6% forecast.[1] The upgrade reflects, among other factors, support from a trade deal with Washington and policy continuity under new leadership in Tokyo.[1]
While these are not blockbuster numbers, they represent a meaningful improvement in a country that has struggled with sluggish growth for decades. A slightly stronger outlook gives the BoJ more confidence that higher borrowing costs will not derail the recovery.
3. Global context: Diverging from the Fed
The timing of the BoJ’s move is also noteworthy relative to the U.S. Federal Reserve. In October, the BoJ kept rates on hold only hours after the Fed delivered its second rate cut of the year, underscoring a growing divergence between U.S. and Japanese policy paths.[1]
Now, with the BoJ pushing rates higher while the Fed has entered a cutting cycle, interest rate differentials are narrowing at the margin. That shift can influence capital flows and currency markets, especially the dollar‑yen exchange rate, which has long been driven by relative yields.
Inside the Policy Debate: A Gradualist but Divided Board
The October 2025 7–2 vote to keep rates at 0.5% revealed a meaningful split within the Policy Board, with Naoki Tamura and Hajime Takata again advocating for a quicker move to 0.75%.[1] Their stance reflected concern that delaying hikes might allow inflation pressures or financial imbalances to build.
Other members preferred a slower approach, emphasizing the need to confirm that wage growth and corporate pricing behavior would support inflation at around 2% over the medium term. The December increase to 0.75% suggests that, with more data in hand, the majority has grown comfortable that conditions are moving in the right direction.

Market Reaction: Yen, Bonds, Equities
The BoJ’s decisions ripple across multiple asset classes—most visibly in the yen, government bonds, and domestic equities.
1. The yen: From chronic weakness to cautious strength?
Japan’s ultra‑low rates were a key driver of yen weakness in recent years, as investors borrowed cheaply in yen to invest in higher‑yielding assets abroad. As the BoJ normalizes while the Fed eases, the incentive for such carry trades diminishes.
A sustained move higher in Japanese yields relative to U.S. and European benchmarks could support a stronger yen over time. That said, moves are likely to be gradual: even at 0.75%, Japanese short‑term rates remain well below U.S. levels, and the BoJ has signaled it will proceed cautiously.
2. Government bonds: End of an era of near‑zero yields
Years of yield‑curve control and massive purchases of Japanese Government Bonds (JGBs) kept long‑term yields artificially low and compressed volatility. As policy normalizes and the BoJ reduces the intensity of its bond buying, the JGB market is regaining a more traditional role in price discovery.
Recent data show that while the BoJ still holds a substantial JGB portfolio, its net purchases have moderated as part of the normalization process.[1] Higher policy rates and more flexible yield management mean investors must reassess duration risk and term premia in the JGB curve.
3. Equities and sector rotation
For Japanese equities, tighter policy is a mixed story. Higher rates can weigh on valuation multiples, especially for highly leveraged firms, but they can also signal confidence in the domestic economy and improve returns for financial institutions.
Banks and insurers, in particular, tend to benefit from steeper yield curves and higher lending rates, while rate‑sensitive sectors such as real estate and utilities may face increased funding costs. The net effect will depend on how quickly rates rise from here and how earnings respond.
Spillovers to Global Markets
The BoJ’s decisions are no longer a purely domestic story. With Japan still a major holder of foreign assets and a key part of global funding markets, shifts in Japanese rates can send ripples across the world.
1. Repricing global bond markets
Japanese investors—pension funds, insurers, and banks—hold significant quantities of U.S. Treasuries, European sovereign bonds, and global credit. As domestic yields rise, the relative attractiveness of foreign bonds can decline, potentially prompting some rebalancing back into yen assets.
Even incremental portfolio shifts can influence global bond yields at the margin, particularly in highly liquid markets like U.S. Treasuries. Investors will be watching BoJ communications and flow data closely for signs of such reallocations.
2. Impact on carry trades and risk sentiment
Higher Japanese rates reduce the appeal of using the yen as a funding currency for leveraged positions in higher‑yielding assets, a strategy at the core of many cross‑border carry trades. If the cost of funding rises further, some of these positions may be unwound, leading to episodes of volatility in emerging‑market currencies, high‑yield debt, or other risk assets.
3. Crypto and alternative assets
The BoJ’s normalization also intersects with risk appetite in newer asset classes like cryptocurrencies. Analysts following Bitcoin have noted that tighter BoJ policy, by raising the cost of leverage and potentially strengthening the yen, can dampen speculative flows from Japanese investors into crypto markets.[2] While crypto is driven by many factors, shifts in global liquidity conditions—of which BoJ policy is a part—remain an important backdrop.
What to Watch Next from the BoJ
Looking ahead, markets are focused less on the December move itself and more on the BoJ’s reaction function: how quickly, and under what conditions, it will continue to raise rates.
- Future rate path: The BoJ has reiterated that it will keep raising borrowing costs if the economy evolves broadly in line with its projections for inflation and growth.[1] That implies a data‑dependent but upward‑tilting rate path.
- Inflation and wage data: Sustained wage growth and stable, domestically driven inflation near 2% are critical to justifying higher rates. Markets will scrutinize labor‑market data and corporate wage settlements.
- Adjustments to bond‑buying: Any further reduction in JGB purchases, or more explicit changes to the management of the yield curve, would signal deeper normalization and could have outsized market effects.
- Communication from Governor Ueda: Speeches and press conferences will remain key for understanding the balance of risks the BoJ sees around growth, inflation, and financial stability.
Conclusion
The Bank of Japan’s decision to raise its policy rate to 0.75%, the highest level since 2008, marks another milestone in its slow exit from ultra‑easy monetary policy.[1] Backed by inflation near target and a cautiously improved growth outlook, the move narrows the gap with other major central banks and reshapes incentives across currency, bond, equity, and even crypto markets.
For investors and policymakers worldwide, the message is clear: Japan is no longer the unchanging anchor of negative rates it once was. As the BoJ continues along the path of normalization, its decisions will carry growing weight in the architecture of global financial conditions.
