Bank of Japan Holds Steady, New Developments in Crypto Market Behind Inflation Relief

The latest policy decision by the Bank of Japan has triggered a chain reaction in global financial markets. Recently, the Bank of Japan maintained its benchmark borrowing rate at 0.75% with near unanimity, while raising its outlook for future growth and inflation. This seemingly contradictory move reflects the central bank’s policy dilemma—inflation has eased, but underlying pressures remain. Accordingly, risk assets like Bitcoin have experienced volatility, falling from recent levels of $90,000 to around $70,670.

Background of Central Bank Policy: Inflation Data Brings Good News but Hidden Concerns

Japan’s December inflation data showed positive signals. According to the Ministry of Internal Affairs and Communications, the Consumer Price Index (CPI), which reflects everyday goods prices, slowed to a 2.1% year-over-year increase in December, down from 2.9% in November. This is the first slowdown in inflation in four months. Core inflation, excluding fresh food prices, also decreased from 3% in November to 2.4%.

However, the central bank remains concerned about deeper price pressures. The core-core inflation rate, excluding both fresh food and energy prices, only slightly declined from 3% in November to 2.9% in December, indicating limited relief. Analysts at ING noted that “aside from monthly fluctuations caused by energy subsidy programs, underlying price pressures persist,” explaining why the bank kept rates steady but raised its outlook for growth and inflation.

Market Reaction to the Bank’s Steady Policy

The Bank of Japan’s stance has not fully reassured markets. While the benchmark rate remains at 0.75%, the yield on 10-year Japanese government bonds rose by 3 basis points to 1.12%. This inverse movement reflects market expectations of future policy adjustments—traders generally believe that, given ongoing potential inflation and higher growth outlooks, the bank may continue to raise rates in the coming months.

Early-week bond market volatility further confirmed these expectations. Japanese government bond yields surged to multi-decade highs amid concerns that tax cuts promised before the February elections could worsen fiscal conditions. The rise in bond yields increased global borrowing costs, including in the U.S., putting significant pressure on risk assets like stocks and Bitcoin.

Bitcoin and Global Financial Markets’ Resonance

As a risk asset, Bitcoin is especially sensitive to central bank policies and bond market movements. Under pressure from rising Japanese government bond yields, Bitcoin dropped over 4.5% on Tuesday, briefly touching $88,000. Although it later rebounded slightly, it is currently trading around $70,670, up 4.04% in the past 24 hours.

Meanwhile, the Japanese yen against the dollar declined by just over 0.20%, to 158.70. The correlation between the yen and Bitcoin reflects a deeper market phenomenon—when central banks face policy tightening pressures, commodities, cryptocurrencies, and emerging market currencies often come under simultaneous stress.

Next Moves for Central Banks and Whether Crypto Can Break Key Support

Analysts say Bitcoin’s next move depends on multiple factors. Geopolitical events (such as incidents related to Iran’s energy infrastructure) could support Bitcoin testing the $74,000–$76,000 range again. However, if external risks intensify or if central bank signals become more hawkish, Bitcoin could further decline toward the mid-$60,000s.

Currently, traders are closely watching central bank officials’ comments and policy expectations. Any hints about future rate hikes could trigger market re-pricing. Meanwhile, altcoins like Ethereum, Solana, and Dogecoin have recently risen about 5%, reflecting market sentiment recovery after the central bank’s decision, but the sustainability of this rebound remains dependent on the ultimate direction of monetary policy.

Macroeconomic Policy Environment and Its Implications for Crypto Markets

Japan’s example serves as a reminder to crypto market participants: central bank policies not only influence traditional financial markets but also profoundly impact the long-term trajectory of digital assets. Easing inflation is generally positive, but when central banks maintain tightening expectations due to fiscal concerns, this benefit can be offset. Investors need to evaluate multiple factors—policy stance, bond yields, geopolitical risks—rather than focusing solely on a single data point.

As major indices like the S&P 500 and Nasdaq fluctuate with changing central bank expectations, Bitcoin’s volatility underscores its nature as a risk asset—every subtle shift in policy can serve as a trigger for market re-pricing.
