The same Olli Rehn warning the ECB about euro-area prices is also Finland's central bank chief. He is sounding a different alarm at home.
Finland's books are still far from balanced. The debt-to-GDP ratio is set to hit 85% this year and climb above 90% by 2027.
Rehn says that path can't go on. But the catch is that one of the biggest pressures on Finland's budget is one Finland can't easily cut: defense.
Rehn said Finland needs about €10 billion in fixes between 2027 and 2034. That is the path to push debt back down.
In US dollars, that is roughly $11 billion over seven years. It works out to about $1.5 billion of fiscal fixes per year.
It has to come from both spending cuts and revenue hikes. Neither side alone can close a gap that big.
Finland already had a parliament-wide deal on debt heading into 2026. Rehn called that "a significant turning point" for trust in the country's books.
He also warned that trust depends on real choices, not just plans. The next test comes early next year, when the parliament's fiscal group sets its goals.
A slow recovery in Finland's economy will help over time. Growth alone won't close the gap.
Finland's defense budget is rising at the same time the rest of the budget needs to shrink. That is the gap Rehn keeps flagging.
Cutting defense isn't a real option. Finland shares a long border with Russia and joined NATO in 2023.
The fix has to come from somewhere else. That means deeper cuts to other spending or higher taxes.
Rehn said a steady fix will work better than a sharp one forced by markets later. Translation: act now, or get forced into worse calls.
Finland is not alone here. Many euro-area countries face the same setup, with rising defense budgets and slower growth on top of older debt.
For investors holding Finnish or Nordic debt, the math is a slow story, not a crisis.
Finland still borrows at low rates and keeps a strong credit grade. But the trend on debt is moving the wrong way. Rating firms tend to act before the math is obvious.
A downgrade for Finland is not on the table this year. But the next few years are when the picture matters.
For Nordic banks and pension funds, Finnish debt is a core holding. Any shift in its rating would ripple across the region.
The Parliamentary Working Group on Fiscal Policy starts setting goals for the coming years early next year. That group is the first real test of the political deal.
Watch the gap between defense plans and the debt plan. If those move in opposite ways for too long, something else has to give.
The other thing to watch is the ECB. If the ECB raises rates this summer, Finland's borrowing costs go up too, which makes the same math worse.
The IMF has flagged the same issue in its 2026 review of Finland. It said the country needs to fix the gap by about 0.5% of GDP each year, which lines up with what Rehn is calling for.
Finland has the room to fix this. It also has a deadline.
