Peru inflation and fuel price trends

In September 2026, Peru experienced significant annual inflation increases in major cities. Data from the Instituto Nacional de Estadística e Informática (INEI) indicated that Lima Metropolitana reached an annual inflation rate of 4.55%, a sharp rise from 1.36% the previous year. This trend was largely driven by rising costs in transportation and fuels, including increases in gasohol and diesel. Arequipa also reported high cumulative inflation at 4.39% for the 12 months ending in September 2026.

By late October 2026, reports from the Osinergmin Facilito platform highlighted variations in fuel prices across Lima and Arequipa. In Lima, gasohol regular prices ranged from 19.89 to 24.75 soles per gallon, while diesel prices were reported between 24.79 and 27.99 soles per gallon. In Arequipa, regular gasoline was priced around 20.35 to 21.59 soles per gallon, with diesel ranging between 24.22 and 24.87 soles per gallon.
