The mechanism
Put the pieces together:
Iceland added 75,000 residents over 2010–2024, two-thirds foreign — a 24% rise on a base of 318,000, the fastest in the developed world over the period. No peer economy absorbed that share of new arrivals in that window, and nothing in the monetary toolkit was built for the economy that did.
Private supply kept up in volume — 26,700 units 2015–2024 — but converged on 70–110 m² owner-occupied apartments priced for the upper half of the income distribution, exactly the product the incoming rental demand could not buy.
Public housing investment — the one channel that could have cleared the queue directly — was shrinking. Real per-person spending on housing and community amenities fell 26% between 2015 and 2024 while the population grew 19%, and the waiting list for low-income rentals doubled to 3,871 households.
Rents rose. Paid rent is up 8.3% over the past year and imputed rent 6.8% — together about 1.5 percentage points of headline inflation — and since May 2023 the rent index has run nine points ahead of house prices.
Services inflation, which carries rent inside it, is running at 8.4% — above the headline number and pulling it up.
Iceland's inflation-indexed contracts then propagate that housing signal economy-wide: indexed mortgages, leases and service contracts adjust automatically, without anyone forming an expectation about anything. Wages catch up later, through kjarasamningar negotiations, not through an automatic link.
The CBI hikes rates, and the tool bites the wrong product. Developers push the pain onto their balance sheets rather than discount — new builds now sit unsold for about 18 months and more than half sell below asking — while a household that could borrow 60 million ISK at 4% can only borrow about 40 million at 8%.
Households with non-indexed mortgages refinance into indexed ones rather than absorb the payment shock. Between 2023 and 2025 they paid down 290 billion ISK of non-indexed debt and took on 523 billion ISK of new indexed debt, preserving cash flow, consumption and housing bids in a single step.
The bite is therefore narrow and perverse: it widens the price cleavage on the wrong product while what gets built, the rental demand driving rents, and the non-profit pipeline all sit untouched. And the forward pipeline is thinning — HMS reports only 58% plot coverage against the capital area's 2025 need, and unique new-build applications entering Reykjavík planning collapsed from 85–90 a year in 2016–2018 to 17 in 2023.
The CBI reads this as a credibility failure and calls for more firmness. But no setting of the policy rate steers developers toward small, affordable rental stock, funds the non-profit queue at the scale the waiting list requires, refills a pipeline no one is starting, or redirects a pension fund out of bank bonds and into a rental building — the tool is not connected to the machinery that matters.
