The Bank of Mexico, or Banxico, targets an inflation rate of 3% with a tolerance threshold of one percentage point above and below that level.

In the first 15 days of July, consumer prices likely increased by 0.28% compared with the previous two weeks, while an increase of 0.22% is expected for the core index, according to the survey.
The survey forecast a year-on-year core inflation rate of 4.55%.
The two-week increase in the National Consumer Price Index (INPC) was likely driven by higher prices of some staples, such as tortillas and liquefied petroleum gas.
