Japan’s Tertiary Industry Index fell 0.5% month on month in December. This was worse than the expected 0.2% decline.
The index measures output in the services sector. The data shows a weaker monthly result than forecast.
Market Reaction And Growth Outlook
The December 2025 report on Japan’s services sector was a negative surprise for markets. It suggests domestic growth was already slowing by the end of last year. This adds to the view that Japan’s economy may struggle to gain momentum in the first quarter of 2026.
This weakness makes it unlikely the Bank of Japan will tighten monetary policy soon. Inflation data from January 2026 already slipped to 1.9%, back below the central bank’s target. As a result, the yen may weaken further against the U.S. dollar, possibly retesting the 158 level seen in late 2025.
In derivatives, this supports buying USD/JPY call options or taking long positions in futures. A weaker yen is also often supportive for Japanese stocks because it lifts the overseas earnings of large exporters. One approach is to buy call options on the Nikkei 225 index, as the currency boost may outweigh worries about slower domestic growth.
Ongoing easy policy can also support Japanese Government Bonds (JGBs). Going long JGB futures may be attractive, since yields could stay low or fall if the economy continues to soften. The downside surprise also raises uncertainty, so buying options to gain exposure to higher market volatility can be a sensible hedge.
