On December 5, 2025, a statement by Tomoyuki Nakamura, a member of the Bank of Japan's Policy Board, made waves in the global financial arena, likened to a stone thrown into a still lake that sends ripples far and wideNakamura, known for his cautious approach, hinted at the possibility of interest rate hikes while underscoring a data-dependent decision-making framework, illuminating the delicate balance the Bank of Japan must maintain between the fragile economic recovery and the pressures for monetary policy normalization.
The uniqueness of Nakamura's recent comments lies in his nuanced shift in stanceHistorically one of the few persistent doves in the central bank’s decision-making body, he had voted against rate hikes in June and September, citing a lack of persistent evidence of wage growthHowever, in his December pronouncement, he acknowledged for the first time that the "option for rate hikes has entered the discussion," albeit with stringent preconditions: substantial confirmation of key economic data before the meeting on December 18.
This shift can be closely linked to marginal improvements in Japan's economic fundamentals

Recent data from Japan's Cabinet Office revised the annualized GDP growth rate for the third quarter of 2025 to 1.2%. Furthermore, business capital investment rose by 2.1%, and export volumes saw a year-on-year increase of 5.3%. Notably, the Bank of Japan's Tankan survey indicated a turnaround in business sentiment, with the confidence index for large manufacturers climbing from -3 to +2, marking the first positive reading in nearly 18 monthsSuch figures provide some backing for the potential normalization of monetary policy.
Nakamura placed particular emphasis on closely monitoring the core Consumer Price Index (CPI) data for November, set to be released on December 12. Market predictions anticipated a decline in the CPI from 2.8% in October to 2.5%. Nevertheless, should unexpected surges in energy prices lead to surprising results, this could reinforce the rationale for raising interest ratesAdditionally, the wage statistics to be published on December 15 will act as pivotal variablesAccording to the Ministry of Health, Labour and Welfare, the average cash earnings across all industries in October increased by 1.8% year-on-year; however, real wages, adjusted for inflation, have experienced a continuous decline for 23 consecutive months.
This heightened sensitivity to data reveals profound internal divisions within the Bank of JapanGovernor Kazuo Ueda, during a speech on November 27, referred to the "prospect of interest rate hikes being on the horizon," while Deputy Governor Masayoshi Amamiya cautioned against underestimating economic downside risksThis divergence in opinions has led to a muddled policy signal, exemplified by a 25 basis-point fluctuation in ten-year government bond yields during the first week of December, further exacerbating volatility in the yen's exchange rate.
Echoing the concerns about the economy's vulnerability, Nakamura repeatedly asserted, "The economy is in a phase of recovery rather than full expansion." This statement highlights the deeper underlying issues facing Japan's economy

Despite the promising GDP data for the third quarter, consumer spending remains tepid—with household consumption in November showing only a 0.4% year-on-year increaseProjections from the Japan Economic Research Center estimate that if real wage growth does not turn positive, the contribution of consumption to GDP will fall to 0.3% in 2026, a decline of 1.2 percentage points from 2024.
Evidence of corporate disparity is becoming increasingly evidentExport-oriented enterprises like Toyota have enjoyed profit gains thanks to currency depreciation, while domestic-focused companies, such as 7-Eleven convenience stores, have witnessed their profit margins contract by 2.3% due to rising cost pressuresA survey by Mizuho Securities revealed that the investment sentiment index for small and medium enterprises has declined for four consecutive quarters, reflecting a cautious outlook regarding the future economic landscape.
The Bank of Japan's decision-making is further complicated by external factorsAn anticipated interest rate cut by the Federal Reserve in December may lead to an escalation of the interest rate differential between Japan and the U.S., thereby intensifying depreciation pressures on the yenData from the Bank for International Settlements (BIS) indicates that Japanese investors hold approximately $2.1 trillion in foreign bonds; should the yield on dollar-denominated assets decline, this could trigger a substantial repatriation of funds, causing yen appreciation.
Japan's current policy dilemma hinges on three key aspects: The first is the trajectory towards achieving its inflation target

Although core CPI has remained above 2% for 18 consecutive months, the core-core CPI, which excludes fresh food and energy, stands at merely 1.2%, indicating a weak undercurrent for demand-driven inflationSecondly, there's an undeniable vulnerability within the financial system, with the banking sector holding around $2.5 trillion in government bonds; a swift rise in interest rates could lead to substantial unrealized lossesLastly, there's limited scope for fiscal policy expansion, as government debt accounts for an enormous 260% of GDP, leaving little room for further fiscal maneuvering.
Market expectations for potential interest rate hikes are already reflected in asset pricesThe yen exchange rate rebounded from a low of 112 in November to 108, while the TOPIX index decreased by 2.1% since December beganAccording to estimates from Nomura Securities, if the Bank of Japan raises rates by 25 basis points in December, Japan’s major banks could see their net interest income increase by ¥380 billion, yet the default rate for loans to small and medium enterprises may rise by 0.3 percentage points.
Considering all these factors, it is likely that the Bank of Japan will adopt a "wait-and-see" strategy during the December 18 meeting, maintaining interest rates while issuing hawkish signalsShould the core CPI stabilize above 2.5% in the first quarter of 2026, coupled with wage negotiations yielding over 3% salary increases in spring, the central bank may execute a third rate hike in April or JuneThis incremental strategy aims to balance the dual objectives of policy normalization and economic stability.
Despite this cautious approach, potential hazards cannot be overlooked
