The Bank of Japan’s December meeting minutes reveal a discussion on keeping monetary policy supportive while adjusting rates as necessary. Members expressed that waiting to raise rates could pose risks given forex’s impact on inflation. Concerns were raised about real rates deviating from equilibrium affecting long-term growth.
Monetary Conditions
The board considered that despite rate increases, monetary conditions would stay accommodative. Concerns were voiced that interest rates might remain negative even after a rate hike to 0.75%. There was agreement to continue raising rates if economic projections align with expectations. Adjusting monetary support was seen as beneficial for market stability.
Many members suggested that rate-hike decisions should be flexible and based on the economy and market conditions at each meeting. It was noted that the BoJ should evaluate numerous factors, including surveys, to assess inflation and wage growth. A gradual rate increase pace was recommended by one member, proposing hikes every few months.
The Bank of Japan has historically maintained an ultra-loose policy to stimulate the economy, which depreciated the Yen. However, it began unwinding this policy as inflation exceeded its 2% target, influenced by global energy prices and rising salaries. This change reversed some Yen depreciation seen in previous years.
The Bank of Japan is signaling it will continue to raise interest rates, which is a significant shift from the policies we saw for years. With Japan’s latest core inflation data from December 2025 holding at 2.4%, the pressure to act remains high. This suggests that any financial instruments betting on a weaker yen face considerable headwinds in the coming weeks.
Strength in the Japanese Yen
Given this outlook, we should anticipate further strength in the Japanese Yen. Looking back at 2025, similar hawkish signals from the central bank consistently pushed the USD/JPY pair lower from its highs above 155. Now trading around 144.50, the path of least resistance for the currency pair appears to be downwards as the interest rate gap with the U.S. narrows.
For derivative traders, this means positioning for a stronger yen through options is a primary strategy. Buying JPY call options or USD/JPY put options could be advantageous, especially as implied volatility may not fully price in the risk of a rate hike at the next meeting. This environment suggests that the cost of protection against a falling USD/JPY could still be relatively cheap.
The justification for higher rates is becoming more embedded in the economy, especially with early signs that the 2026 spring wage negotiations will secure increases above 4%. Even after the rate hikes in 2025 brought the policy rate to 0.75%, Japan’s real interest rates remain negative. This gives the Bank of Japan plenty of room to continue its policy normalization without choking off the economy.
However, the central bank has emphasized that the pace of rate hikes is not predetermined and will depend on incoming data. The modest but positive GDP growth of 0.3% in the last quarter of 2025 suggests a cautious approach. Traders should therefore manage risk, as the timing of the next hike remains uncertain, creating potential for short-term volatility.
