Japan’s capacity utilisation rose by 1.3% in December, compared with -5.3% the month before.
That is a swing of 6.6 percentage points from the prior reading.
Capacity Utilisation Signals Industrial Rebound
Japan’s jump in capacity utilisation in December 2025 is a clear bullish signal. It reverses the prior month’s drop and suggests the industrial sector ended the year stronger than expected. We think this strength is likely to carry into the first quarter of 2026.
This upside surprise could support Japanese equities in the weeks ahead. Higher factory use often leads to higher output and better earnings potential, which can make the Nikkei 225 more attractive. We should consider buying Nikkei futures or near-term call options to position for more upside.
Other recent data supports this view. Japan’s industrial production in January 2026 rose by a seasonally adjusted 1.1%, beating consensus forecasts. The latest Tankan survey of large manufacturers also showed business confidence at its highest level in more than a year. Together, these signals point to a broad recovery.
A stronger economy may also push the Bank of Japan to rethink its ultra-loose policy earlier than expected. That would likely support the Japanese yen. Derivatives traders could consider buying put options on USD/JPY, aiming to benefit if the yen strengthens against the dollar.
We have seen similar moves before. In parts of 2023, speculation about policy normalisation helped the yen strengthen quickly. Today’s data looks stronger than it did then, which suggests that even small policy signals could cause a sharper move. That history supports the case for a stronger yen.
Positioning For Higher Yen Volatility
Uncertainty about the Bank of Japan’s next steps may raise implied volatility in FX markets. This can favour options strategies that benefit from bigger price swings, such as long strangles on USD/JPY. We should expect larger yen moves as markets adjust to this new set of data.
