Japan’s national consumer price index (CPI), excluding fresh food, rose 2% year on year in January. This matched the forecast.
The data point refers to the core CPI measure that removes fresh food prices. It is used to track inflation trends with fewer short-term swings.
Bank Of Japan Policy Implications
With Japan’s core inflation hitting the Bank of Japan’s 2% target, we see this as a pivotal moment. The number being in line with forecasts means no immediate shock, but it solidifies the case for the BoJ to finally exit its negative interest rate policy. We must prepare for a significant policy shift, likely at the March or April meeting.
This development strengthens the yen, putting downward pressure on the USD/JPY currency pair. Recent market data shows a sharp increase in demand for JPY call options, suggesting a strong consensus is forming around yen appreciation. We should consider positioning for a move towards the 140-142 level by purchasing USD/JPY puts or selling futures.
The end of Yield Curve Control is now a question of when, not if, which means Japanese Government Bond (JGB) yields are set to rise. As of this week, overnight index swaps are pricing in a 70% probability of a 10-basis-point hike by April 2026. Shorting JGB futures is the most direct way to trade this anticipated rise in yields.
For equities, a stronger yen typically acts as a headwind for the export-heavy Nikkei 225 index. We saw this pattern play out in the second half of 2025 when yen strength briefly shaved 5% off the index. Hedging long equity exposure with Nikkei puts or selling index futures could protect portfolios in the coming weeks.
What makes this inflation reading different from the temporary spikes we saw in 2024 and 2025 is the backing of wage growth. Preliminary reports from this month’s “shunto” spring wage negotiations are indicating average pay increases of over 3.5%, the highest in decades. This suggests inflation is becoming sustainable and gives the BoJ the final piece of evidence it needed.
Volatility And Positioning
The key takeaway is that volatility is returning to Japanese markets, which have been suppressed by BoJ policy for years. Options that profit from price swings, such as straddles on major currency pairs and indices, will likely be valuable. We will be closely watching statements from BoJ officials for any change in tone, as their words will now carry immense weight.
