Peru’s consumer price index (CPI) moved into negative territory in May 2026, signaling a sharp month‑over‑month turnaround in price dynamics. The CPI registered a -0.16% change in May, compared with a 0.52% increase recorded in April 2026, according to data updated on 1 June 2026.
On a month-over-month basis, the latest reading shows that prices in May not only slowed but actually declined versus April, after having risen notably in the previous month. In April, the 0.52% gain reflected a clear upward move from March, while May’s -0.16% result points to an abrupt cooling in price pressures heading into mid-year.
The comparison underscores increased short-term volatility in Peru’s inflation path. The “actual” figure for May compares the change in prices from April to May, while the “previous” figure for April reflects the change from March to April, highlighting how quickly the monthly inflation trend has shifted.
