Rising-rate mortgage: monthly payment jumps from €390 to €922

The rising-rate mortgage eating into salaries: from €390 to €922

The payment comes out of the same account. The amount, however, does not. A family that signed their mortgage in 2006 has seen their monthly bill jump from €390 to €922. The list of adjustments accompanying this figure is typical for a squeezed household: cutting streaming subscriptions, dropping Amazon Prime, shopping for deals, buying cheaper clothes, and ending children's extracurricular activities. Also gone is the cleaner who came two days a week.

The case, reported by outlets like 20minutos, has put under the spotlight a product almost nobody re-reads when signing: the rising-rate mortgage. It starts with a low payment that increases every year. With Euribor at 4%, the combination becomes suffocating for those who didn't do the math at the time.

What is a rising-rate mortgage and why does the payment increase?

In a standard French amortization mortgage, the ratio between interest and principal is fixed by the rate and term. The rising-rate mortgage works similarly but with a twist: the bank sets a lower initial payment and raises it annually, by around 1.5% per year. Immediate consequence: less principal is repaid initially, and debt takes much longer to decrease.

It sounds manageable while Euribor is stable or falling. It stops sounding so when the index turns, because then the bill grows via two paths simultaneously: the scheduled increase and the rate review. Hence the label given by less friendly analysts: time bomb.

Today's Euribor isn't higher than in 2006

Here appears the nuance that dismantles half the anger. Those who signed in 2006 did so with Euribor at 2.833% in January and 3.921% in December. Today it hovers around 4%. The current rate is practically where it was nearly two decades ago.

From this comes an uncomfortable conclusion for the victim narrative: a variable mortgage signed in that year pays today something similar to what it paid then, not much more, despite 17 years having passed. The real blow is taken by those who entered later, during the cheap money window, and found themselves with a bill that had only been going down until it stopped doing so.

The anomaly isn't the 4%, it's the 0%

For nearly a decade, the price of money stayed at historic lows. What was an exception became normalized. Interest rates of the seventies, eighties, and nineties, with strong and sustained rises, live in the memory of another generation, not in that of those who signed after 2009.

The calculation is ruthless. Whoever fixed their mortgage at 2.5% in 2019 didn't make a brilliant move, they did the obvious thing. And there was a period where fixed rates were offered at 1.29% without ties; whoever missed that window now faces upward revisions without a safety net.

From extreme case to headline: the media filter

Another line of criticism points to the showcase. Cases that open news broadcasts are usually the most extreme: the 2006 rising-rate mortgage or the one who borrowed 100% of value with zero savings. That alone makes headlines. Then, almost quietly, more normal examples slip in where the increase squeezes but doesn't derail life.

The underlying suspicion is that the headline selects the tail of the distribution, not the average, and that public discussion ends up debating that tail instead of the product design and who marketed it.

Prepaying, saving, or refinancing: the exits available

With hindsight, the alternatives were three: prepay capital in the loan's early years, save surplus to attack debt when the rise arrived, or switch products in time. None are free, and the first clashes with the logic of a payment that has barely started eating into principal.

On this, there is mutual reproach. On one hand, 17 years allow for much and there was room to reduce debt rather than stretch it. On the other, a 40-year loan with a tight payment leaves no room for heroics, and the product was sold without fully explaining its mechanics. In practice, what repeats most is subrogation to another entity or novation to a fixed rate before the index turns. There is even a story of someone warned months in advance via messaging who let it pass.

Remains the data that reorders the conversation. A mortgage of €120,000 over 30 years, signed in 2003, was paid at the worst moment of 2006, with Euribor skyrocketing, for about €700. Years later, with the index below zero, the same payment fell to about €404. Two extremes, one loan. Neither resembles the €922 that triggered alarms, and that distance exactly explains why the diagnosis changes depending on who signs the contract and when.
