Japan National CPI Ex Food and Energy (YoY)
Published:
A measure of annual Japanese consumer-price inflation that removes fresh food and energy to focus on underlying price pressures.
Full explanation
Japan National CPI Ex Food and Energy (YoY) measures the annual change in consumer prices paid by households across Japan after excluding fresh food and energy. It is designed to give a clearer view of underlying consumer-price pressures by removing categories that can be especially volatile. The Statistics Bureau compiles the index from prices for a representative basket of household goods and services. The year-on-year rate compares the index with the same month a year earlier.
Why traders watch it
It is a closely watched measure of underlying Japanese inflation that can influence expectations for Bank of Japan policy, Japanese government bond yields and the yen.
Market interpretation
- JPY foreign-exchange pairs
- Surprises can alter expectations for Japanese monetary policy and produce short-term volatility.
- Japanese government bonds
- The release can influence expectations for future policy settings and inflation compensation.
Stronger vs weaker outcomes
A higher-than-expected reading may be interpreted as firmer underlying inflation pressure and may increase attention on less-accommodative monetary-policy expectations. A lower-than-expected reading may suggest softer underlying inflation pressure and may have the opposite effect on those expectations.
A result above expectations may be seen as evidence of firmer underlying inflation and can draw more attention to less-accommodative Bank of Japan policy expectations.
A result below expectations may be seen as evidence of softer underlying inflation and can reduce attention on less-accommodative policy expectations.
Higher-than-expected underlying inflation may strengthen expectations for less-accommodative policy, while a lower reading may soften them.
Typical volatility
High. The exclusion is specifically for fresh food and energy, not necessarily every food-related item. Base effects, changes in administered prices and methodological revisions can affect the year-on-year rate, so the result is commonly considered alongside headline CPI and CPI excluding fresh food.
Trading considerations
- Check the release against consensus expectations as well as the prior reading and any revisions.
- Compare it with headline CPI and Japan's CPI excluding fresh food, which covers a different basket.
- Consider base effects and energy-related policy changes when assessing year-on-year movements.
- Spreads and short-term volatility may widen around the scheduled release time.
