Suspect 1: The króna

The first place any Icelandic inflation story begins is the currency. Iceland has a 400,000-person economy with its own floating currency, a long history of depreciation-driven inflation spirals, and a post-2008 national trauma around the króna's role in the banking collapse. Whenever inflation prints hot, the reflexive question is "what happened to the króna?"

Let's check the alibi. Here is Iceland's CPI for March 2026, decomposed:

Look at that second line. Imported goods are deflating. The basket of stuff Iceland buys from abroad — cars, electronics, clothing, foreign food, industrial inputs — is cheaper in March 2026 than it was in March 2025. Whatever is driving Iceland's headline number, the króna is not passing foreign inflation through to Icelandic shelves. The currency channel is working. World prices have cooled, and the króna has been importing that cooling for about eighteen months. If the króna were the culprit, the imported-goods line would be hot. It is the coldest line in the table.

Suspect cleared on the direct pass-through charge. But the króna is not done being interesting.

The carry trade

Iceland's policy rate is 7.50%. Here is what the rest of the developed world looks like:

Iceland is running a policy rate four times Sweden's and nearly four times the ECB's. That differential is an open invitation: borrow in euros at 2%, park in króna at 7.5%, pocket the spread. This is the carry trade — the same mechanism that, in its most extreme pre-2008 form, fueled the jöklabréf. The CBI knows it is happening. Over just a few months in mid-2025, it purchased 29.3 billion ISK in foreign currency — nearly 40% of total FX market volume in the period — to prevent carry-driven appreciation from distorting the exchange rate. Foreign reserves stood at 917 billion ISK by late 2025.

Think about what that means operationally. The CBI keeps rates high to fight inflation. The high rates attract speculative capital inflows. The inflows push the króna up. The CBI intervenes in the FX market to prevent excessive appreciation that would hurt exporters. And the inflation the CBI was trying to fight has not budged, because — as we will see — it is driven by housing, not by anything the exchange rate touches. The CBI is running two policies that partially cancel each other out: tight money to cool the economy, and FX purchases to offset the side effects of tight money on the currency. This is the impossible trinity of open-economy macroeconomics playing out in real time — independent monetary policy, free capital movement, and a managed exchange rate. Pick two. Iceland is trying to run all three and spending reserves to paper over the contradiction.

The "drain" fear

The counter-argument that keeps rates high is capital flight: "if we cut, money will leave, the króna will crash, import prices will spike, and we'll get the inflation we were trying to avoid." This is the argument that sustains emergency-level rate differentials even when the CBI suspects the rates are not reaching the actual inflation driver.

But look at which direction the capital is actually flowing. The risk right now is carry inflows, not outflows. The CBI is buying foreign currency to prevent appreciation, not selling it to defend against depreciation. Iceland does run a small current account deficit — around −2% to −3% of GDP over the past four years, driven by a structural goods trade deficit (roughly −8% of GDP in 2025) that the services surplus from tourism (+5.5%) only partly offsets. But that is a flow, and flows are the wrong object for a capital-flight scenario anyway. The stock — Iceland's net foreign-asset position — tells the opposite story. Iceland's net international investment position was +44% of GDP at end-2025 (Seðlabanki, Fjármálastöðugleiki 2026/1). Iceland is a substantial net creditor to the rest of the world, not a debtor. The reason is the pension fund system: pension funds hold total assets of 179% of GDP, of which 42% — roughly 70% of GDP — is invested abroad. That single line item exceeds Iceland's entire positive NIIP on its own. Every other resident sector (banks, government, households, non-financial corporates) is a net foreign debtor on balance, and pension fund foreign holdings still cover all of them with room to spare. In the central bank's own words: "Jákvæða erlenda stöðu má fyrst og fremst rekja til erlendra eigna lífeyrissjóða" — the positive external position can be attributed first and foremost to pension fund foreign assets. The "drain" scenario requires you to believe Iceland is permanently one rate cut away from a currency crisis — that the króna is, in essence, hopeless.

That belief has a specific historical basis: the 2008 collapse. But the 2008 capital flight was a banking insolvency event. Money left because the three major banks owed roughly ten times GDP and could not pay. They had used the króna as a vehicle for cross-border carry, and when that carry unwound, the currency followed. Today's banking system holds assets of roughly 1.5 times GDP, is well-capitalized, and carries no significant cross-border liabilities of that kind. The institutional environment that made the króna a crisis currency has been dismantled.

Other small-currency economies confirm this is not a size problem. New Zealand (5 million people) runs a 2.25% policy rate. Norway (5.5 million) runs 4.00%. Sweden (10.5 million) runs 1.75%. None of them maintain emergency-level rate differentials to prevent capital flight. None of their currencies have collapsed. The króna's historical volatility was a banking-regulation failure, not a currency-size failure — and that banking system no longer exists.

Suspect 1 has an alibi on the pass-through charge and a good defense on the "drain" charge. The króna is not driving inflation. But the króna is the historical justification for something else — Iceland's system of CPI-indexed financial contracts, the verðtrygging. In Icelandic policy discourse, the two are often treated as inseparable: you have the króna, therefore you must have indexation. That conflation is a mistake, and it matters enough to deserve its own suspect file.
