Inflation (CPI) during each prime minister's tenure
Every prime minister since 1991, ranked by how the inflation (CPI) changed from their first day in office. Politare shows what happened during a tenure; it does not claim the office-holder caused it.

Sorted by total, highest first. Every row is indexed to the last month complete before the first day in office ("from" marks a start that had to move because that period had no data, or because the period cut it); Levels are per cent changes, rates are differences in pp; "per year" compounds levels and divides rates. Tenures with under 12 months, or under three observations, are left out. % change on a year earlier · Statistics Iceland, consumer price index (VIS01000, base May 1988 = 100), its own change on the same month a year earlier · Iceland data · as of Oct 2026.
