Mexico’s consumer price index (CPI) turned negative in May 2026, signaling a month-over-month decline in prices after a modest increase in the previous month. According to data updated on June 9, 2026, CPI fell by 0.21% in May on a month-over-month basis, compared with a 0.20% rise in April 2026.
The shift from positive to negative territory on a month-over-month basis indicates that price pressures eased notably between April and May. While the previous reading showed inflationary momentum, the latest figure points to a brief deflationary move in consumer prices over the month. Investors and policymakers will now be watching upcoming releases to determine whether May’s decline is a one-off adjustment or the start of a softer inflation trend in Mexico.
