At the same time, interest rates had been cut to a historical low, and financing terms were more favourable than before. Demand for real estate surged, and house prices did likewise. Added to this was the Government’s response to the volcanic activity on Reykjanes peninsula, which included a large-scale buy-up of residential housing from Grindavík residents. As a result, inflation in Iceland was no longer a predominantly imported phenomenon but instead was largely demand-driven.
Six years of above-target inflation
Now, six years after inflation started to gain steam, we are still battling the same problem. Even though inflation has tumbled from its last peak, it has been enormously difficult to bring it within striking distance of the target.
Numerous shocks, domestic and foreign, have struck over this period. The main shock unique to Iceland was the spate of earthquakes and volcanic eruptions on Reykjanes peninsula, which delayed disinflation, although overseas wars and heightened global economic uncertainty have also affected prices in Iceland.
The CBI has responded by raising interest rates sharply. Inflation finally started to yield, and for a while in 2025 it hovered around 4%, the upper tolerance limit of the inflation target. It has been heading upwards again since year-end 2025, however, and hit a two-year high this August. This gives rise to an important question: What is causing this inflation, and why has it been so hard to bring it back to target?
Services inflation at the centre of the stage
At present, services prices are the main antagonist in the inflation drama. Of the 5.6% headline inflation rate, about 5 percentage points can be attributed to services items. In other words, services are responsible for about 89% of total inflation.
In general, services prices are stickier than goods prices. This is because the price of services depends largely on wage costs, which are naturally more inelastic than, for instance, the global price of commodities and other inputs, with its propensity to fluctuate widely. The past years’ steep pay rises have probably contributed to ongoing inflationary pressures. As a result, services inflation often tapers off more slowly than inflation caused by temporary supply chain volatility, the ISK exchange rate, or commodity prices. Wage agreements therefore have a major impact on developments in services inflation. Unlike many of the determinants of goods prices, wage developments are often a known quantity for a period of time stretching into the future, particularly when long-term wage agreements are made. This can cause services inflation to be more predictable than it would be otherwise.
Housing
Housing is the single largest services item in inflation, accounting for about 1.7 percentage points of the current 5.6% headline rate. The contribution from the housing component has been broadly at this level in recent months and explains just over 30% of total inflation. At the peak, however, over half of headline inflation was due to housing. Although housing is still the single largest inflation component, it carries is far less weight now than when inflation was at its peak.
Housing has a significant impact on the CPI, as the housing component carries the most weight in the index. The largest subcomponent of housing is imputed rent, which currently weighs just under 21% in the CPI. This reflects how large a share of household spending is due to housing costs.
In order for inflation to return to target, it is important to slow down the increase in imputed rent. There are signs of improvement on the horizon, though, as the real estate market has cooled substantially in the recent past and real house prices have begun to fall. Imputed rent has been quite stubborn, however, and has risen persistently.
One explanation for this could be that Statistics Iceland (SI) changed its imputed rent calculation methodology in 2024 and now relies on developments in rent prices rather than house prices. Since that change was put into effect, rent prices have fallen more slowly than house prices, and imputed rent has fallen more slowly still. Thus the impact of housing on inflation has tapered off more gradually than it would have otherwise.
The large share of inflation-indexed rental leases could explain this to some extent. Such leases adjust automatically with changes in the CPI and can therefore create a spiral between rent prices and inflation. This may explain why imputed rent has been more tenacious than might be expected based on developments in rent prices.
