Mexico Mid-month Inflation Rate
An early fortnightly measure of annual consumer-price inflation in Mexico.
Full explanation
Mexico Mid-month Inflation Rate YoY shows how consumer prices in Mexico's first half of a month compare with the same half of the month a year earlier. It is derived from the National Consumer Price Index (INPC), which tracks the average change in prices paid by households for a representative basket of goods and services. INEGI calculates the index at both fortnightly and monthly frequencies and publishes the first-half result during the month. The YoY figure is an annual inflation rate for that fortnight, rather than a comparison with the prior full month.
Why traders watch it
It offers an early reading on Mexican consumer-price pressures, which can influence expectations for Banco de México policy, Mexican interest rates and the MXN.
Market interpretation
- MXN
- Can prompt repricing of inflation and monetary-policy expectations, particularly when the result differs materially from consensus.
- Mexican government bonds and interest-rate markets
- May influence expectations for future policy rates and inflation compensation.
Stronger vs weaker outcomes
A higher-than-expected annual rate may be interpreted as firmer inflation pressure, while a lower-than-expected result may be interpreted as softer pressure. Market interpretation can also depend on core and non-core components, the fortnightly change and implications for the broader inflation path.
A higher-than-expected YoY rate may be viewed as evidence of firmer consumer-price pressure, especially if the increase is broad-based or accompanied by firm core inflation.
A lower-than-expected YoY rate may be viewed as evidence of softer consumer-price pressure, particularly if core measures also ease.
Compare the result with forecasts, the prior reading, the fortnightly change and the core versus non-core breakdown.
Typical volatility
High. This is a fortnightly reading and can be affected by temporary or seasonal price movements. The headline rate alone does not show which components drove the result, and later inflation releases provide additional context.
Trading considerations
- Expect liquidity and spreads to change around the scheduled release time.
- Compare the headline annual rate with core and non-core inflation measures where available.
- Check the fortnightly change as well as the annual rate; they answer different questions.
- Treat the later monthly and second-half INPC release as important confirmation or context.
- Consider other releases and Banco de México communications when assessing the market reaction.
