Japan is due to publish several major economic releases next week, after a weaker-than-expected recovery in fourth-quarter GDP. January industrial production and retail sales are forecast to rise.
Tokyo CPI inflation is expected to ease further as energy, utility, and food prices soften. Core inflation excluding fresh food is projected to fall below 2%.
Near Term Data And Policy Expectations
With core inflation below 2%, the Bank of Japan is expected to keep its policy rate unchanged at 0.75% at the March meeting. The report notes that fiscal spending and winter bonuses may be supporting January activity figures.
Back in early 2025, we saw a view that Japan’s rebounding activity would be met with easing inflation, allowing the Bank of Japan to remain steady. The expectation was that core inflation would fall below 2%, keeping the policy rate locked at 0.75% through the March 2025 meeting. This outlook suggested a period of low volatility and predictable policy.
However, inflation proved to be much stickier throughout 2025 than was anticipated. While Tokyo’s core CPI did briefly dip, it has since accelerated and is now holding at 2.8% year-over-year as of January 2026, driven by wage pressures and a weaker currency. This persistent overshoot of the 2% target has changed the entire policy landscape.
Consequently, the Bank of Japan was forced to abandon its steady stance later in 2025, raising its policy rate to 1.00% in a move that surprised many who expected a longer pause. Current market pricing now implies at least two more rate hikes are possible before the end of this year. The era of a passive central bank that we saw last year appears to be over.
Implications For Yen And Rates Volatility
A key driver has been the yen, which has weakened further against the dollar to the 162 level, a multi-decade low not seen since the late 1990s. This continues to inflate the cost of imports, creating a difficult feedback loop for the central bank. This sustained currency weakness keeps upward pressure on both inflation and the need for higher interest rates.
For derivative traders, this means strategies that bet on low volatility in Japanese rates are now risky. Instead, positioning for higher-than-expected swings in Japanese government bond (JGB) futures could be beneficial. The market may be underpricing the potential for the Bank of Japan to act more aggressively than currently forecast.
In the currency space, this environment makes yen derivatives particularly interesting. Given the extreme weakness of the currency, options strategies that would profit from a sudden reversal, such as buying cheap, out-of-the-money JPY calls, could offer a favorable risk-reward profile. Any unexpectedly hawkish commentary from the Bank in the coming weeks could trigger a sharp rally in the yen.
