Iceland's annual inflation rate rose to 5.4% in March, the strongest pace in 18 months, official data showed on Thursday. The consumer price index (CPI) reading matched the forecast published by Landsbankinn hf and was close to Islandsbanki hf's projection of 5.5%.
The March CPI result is the highest level recorded since September 2024. Authorities and market-watchers cited higher crude oil prices as a key factor behind the upward pressure on consumer prices. Those oil price gains are tied to tensions in the Middle East, which have prevented some oil tankers from using the Strait of Hormuz and restricted the movement of crude cargoes.
Earlier in the month, Iceland's central bank implemented its first interest-rate increase since August 2023. The monetary authority has warned that it is likely to raise its policy rate by another quarter-point at its next scheduled decision, which is set for May 20. The central bank's move made Iceland the first western European monetary authority to tighten policy in response to concerns that the conflict in the Middle East could sustain elevated inflationary pressures.
The sequence of events - rising oil costs, a renewed pickup in consumer inflation, and an early return to rate increases by the central bank - underscores the transmission of global energy market stress into domestic price dynamics. The March data arrived in line with one major bank's forecast and only a tenth of a percentage point below another's estimate, indicating the outcome was broadly anticipated by local financial institutions.
With the central bank indicating the probability of an additional quarter-point hike at its May meeting, markets and businesses will be watching forthcoming data and policy statements closely. The authorities' decisions in coming weeks will be framed by how persistent the oil-driven price pressures prove and by subsequent CPI readings.
Summary
Iceland's CPI rose 5.4% year-on-year in March, the strongest inflation rate since September 2024. The increase matched Landsbankinn's forecast and was close to Islandsbanki's 5.5% estimate. Higher crude oil prices, linked to the Middle East conflict and disruptions to tankers transiting the Strait of Hormuz, are cited as a primary driver. The central bank has already tightened policy once and signaled the likelihood of an additional 25 basis-point increase at its next decision on May 20.
