Homeowners with step-up mortgages—loans that begin with a low initial monthly payment that rises gradually over time—are now being offered the chance to convert them into fixed-rate, amortising loans. Doing so can save borrowers several thousand euros and lock in a lower, preferential interest rate for the remainder of the loan term.
A Limited-Time Opportunity
This conversion option is available until 31 December 2026. Under it, borrowers can secure a fixed interest rate—currently proposed by banks at around 3%, reflecting pre-rate-hike levels—and ensure that their monthly payments go toward repaying both principal and interest from the outset. This avoids the large ‘balloon’ repayment typically due at maturity—a key risk factor behind the European Central Bank’s (ECB) recent directive.
Why the ECB Is Acting
The ECB has instructed banks to reclassify step-up loans as higher-risk exposures due to the elevated default risk posed by the balloon payment. That risk is expected to intensify further following the ECB’s latest interest rate hike—announced last Thursday—which marks the start of a new cycle of rising euro-area rates. With step-up loans tied to variable rates (currently hovering near 5%, based on the Euribor), rising benchmark rates mean more of each payment goes toward interest and less toward reducing the principal—leaving a larger outstanding balance to settle at maturity.
Real-World Savings
Consider a borrower with an existing step-up mortgage: €100,000 remaining, a variable rate of 4.72%, and 242 months left. Under current terms, total repayment would reach approximately €188,000. By converting to a fixed-rate amortising loan at 3%, the same borrower would repay just €135,000—saving €53,000, or 28%.
Monthly payments would rise from €340 to €557, but this increase must be weighed against the alternative: under the original step-up structure, the final monthly payment would climb to €615, while the unpaid principal ballooning to €74,000 at maturity.
For those seeking lower monthly outlays, banks also offer the option to extend the loan term by 60 months—bringing it to 302 months—with a fixed 3% rate and a reduced monthly payment of €478. While this extends the repayment period, it still avoids the balloon risk and delivers significant long-term savings compared to the original structure.
