Biweekly CPI (first half of month) in Mexico

Mexico is one of the few countries that publishes its consumer price index TWICE a month. Around the 24th, INEGI releases the CPI for the first half of the current month: an early read on monthly inflation, about two weeks ahead of the full monthly figure (released on the 9th of the following month, in its own sheet). Both the headline and the core index (which excludes agricultural goods, energy and government-set tariffs) are published. The 'monthly' change quoted by INEGI and the press is actually the change from the previous fortnight; the annual rate compares with the same fortnight a year earlier. It is one of the readings closely watched by Banco de Mexico's board.
