Rising interest rates: what changed and what could change by the end of 2026
After a cycle of cuts in 2024 and 2025, the European Central Bank (ECB) raised interest rates again in June 2026. For people with a Portuguese mortgage, prospective homebuyers and borrowers comparing offers, this raises practical questions: how much could the monthly payment rise, which rate structure is suitable, and is it better to buy now or wait?
On 11 June 2026, the ECB raised all three key rates by 0.25 percentage points. On 23 July, it kept them unchanged: 2.25% for the deposit facility, 2.40% for the main refinancing operations and 2.65% for the marginal lending facility.
The context has changed, but there is no guaranteed path for the coming months. The ECB has said that it will decide meeting by meeting, based on inflation, economic activity and monetary-policy transmission. This article therefore separates confirmed developments from possible scenarios up to 31 December 2026.
What changed in 2026?
Following earlier cuts, key rates remained stable through much of 2025 and early 2026. In June 2026 the ECB reversed direction, citing renewed inflationary pressure, particularly from energy prices.
The June Eurosystem projections put average headline inflation at 3.0% in 2026, 2.3% in 2027 and 2.0% in 2028. These figures are a central scenario, not a promise, and remain exposed to substantial energy and geopolitical uncertainty.
The ECB paused in July. That does not prove that the tightening cycle is over; it only records the decision made with the information available at that meeting.
How do ECB decisions affect a Portuguese mortgage?
The ECB does not set the rate in your mortgage agreement directly. Its decisions do, however, influence funding costs and market expectations across the euro area.
For a variable-rate Portuguese mortgage, the nominal annual rate is normally:
Nominal annual rate = contracted Euribor + bank spread
When the relevant Euribor is reset — commonly every 3, 6 or 12 months — the payment is recalculated under the contract. An ECB decision therefore does not necessarily change your payment the following day.
With a mixed-rate mortgage, the payment is protected from index movements during the initial fixed period. It then switches to the variable formula set out in the agreement.
With a fixed-rate mortgage, market-rate changes do not alter the contracted rate during the fixed period. They may still affect new offers, renegotiations and transfer costs.
How much could the monthly payment rise?
The impact depends on the outstanding balance, remaining term, current rate, size of the increase and the index reset date.
Consider a simplified repayment mortgage of €200,000 with 30 years remaining:
| Illustrative annual rate |
Approximate monthly payment |
Change from 3.00% |
| 3.00% |
€843 |
— |
| 3.25% |
€870 |
+€27 |
| 3.50% |
€898 |
+€55 |
| 4.00% |
€955 |
+€112 |
The calculation assumes a constant rate and excludes insurance, fees and other costs. It is neither a commercial offer nor a Euribor forecast.
Larger outstanding balances and longer remaining terms are generally more sensitive to rate changes. A personalised calculation should use the actual balance, term and contract terms.
Buy a home now or wait?
There is no universal answer. The decision also depends on the property price, rent currently paid, income stability, deposit, emergency savings and how long you expect to keep the home.
Reasons to proceed now
- Finding a suitable property within budget may matter more than attempting to time the lowest rate.
- A stronger deposit can reduce the amount borrowed and the payment.
- Fixed and mixed offers can provide a degree of predictability.
- More favourable future conditions may create an opportunity to renegotiate or transfer, after all costs are considered.
Risks of proceeding now
- Market rates may rise again, affecting variable-rate loans and future resets.
- Borrowing at the limit of affordability leaves little room for unexpected expenses.
- A manageable mixed-rate payment may increase when the fixed period ends.
- Using all savings for the deposit and taxes can leave no emergency fund.
Reasons to wait — and the trade-offs
Waiting may allow you to build a larger deposit and repay other debts. However, rates may not fall, property prices may rise and rent paid while waiting is also a cost.
Rather than trying to predict the exact market turning point, ask whether the payment remains comfortable if the rate rises by 0.5 or 1 percentage point, whether you have adequate reserves and whether the property suits your medium-term needs.
Is it worth transferring your mortgage?
A transfer may make sense when another bank offers a lower total cost, more stability or terms that better fit your circumstances. Compare more than the spread and advertised monthly payment.
Check the nominal rate, APR, total amount payable, insurance, linked products, valuation and legal costs, early-repayment charges, new term and total cost through maturity.
As a general rule in Portugal, the maximum early-repayment commission may reach 0.5% of the amount repaid during a variable-rate period and 2% during a fixed-rate period, unless a legal or contractual exemption applies. The temporary waiver for certain variable-rate primary-residence mortgages ended on 31 December 2025, so the position in 2026 should be checked against the contract and the bank's information.
A lower monthly payment is not necessarily a cheaper solution. Extending the term may reduce the payment while increasing total interest.
Fixed, mixed or variable: which makes sense now?
Each structure manages a different risk. The right choice depends on cash-flow resilience, tolerance for fluctuations and the expected life of the loan.
| Structure |
May suit borrowers who… |
Main point to check |
| Fixed |
value predictability and accept its price |
initial rate and early-repayment charge during the fixed period |
| Mixed |
want stability in the first years and accept later Euribor exposure |
payment, spread and index after the fixed period |
| Variable |
have room for fluctuations and want to track Euribor |
payment may rise at index reset dates |
According to Banco de Portugal, 85% of new primary-residence mortgages in April 2026 used a mixed rate. This shows recent market preference; it does not establish that mixed rates are best for every borrower.
Compare offers using the same amount and term, and review the APR, total amount payable, insurance and an adverse-rate scenario.
How to limit the impact of higher payments
Stress-test the budget
Model increases of 0.5 and 1 percentage point. If possible, save the difference for several months to test your true margin and build a reserve.
Review insurance and linked products
A lower spread may require products whose cost removes the benefit. Compare insurance inside and outside the bank and ask what happens if each linked product is removed.
Consider partial repayment
Reducing the balance may lower the payment or, subject to renegotiation, shorten the term. Check the commission and keep adequate emergency liquidity.
Renegotiate or compare a transfer
Ask the current lender to review the spread, insurance or other conditions and compare that result with equivalent offers from other banks.
Act before missing a payment
Contact the lender early if you anticipate difficulty. Taking unsecured credit to pay the mortgage can increase the risk of over-indebtedness and requires careful analysis.
Mistakes to avoid before applying
- Looking only at the initial payment.
- Comparing only the spread rather than APR, total amount payable, insurance and fees.
- Using all savings for the purchase and leaving no emergency fund.
- Signing a promissory purchase agreement without appropriate financing protection.
- Taking out new credit before the bank's final decision.
- Omitting information or overstating income.
- Relying on future rate cuts to make the loan affordable.
- Failing to read the European Standardised Information Sheet (ESIS/FINE).
What could happen by the end of 2026?
As at 4 August 2026, three facts matter: the ECB raised rates in June and held them in July; its June projections put inflation above 2% in 2026 and 2027; and it has not committed to a specific number of further increases or cuts.
This leaves several scenarios open:
- Rates remain stable if inflation and energy prices stay close to the expected path.
- Further increases if inflation pressure persists or spreads more broadly.
- Later relief if inflation and economic activity weaken more sharply, although cuts in 2026 are not guaranteed.
Euribor incorporates market expectations and can move before official decisions. It also need not follow ECB rates point for point. A resilient household plan should therefore work under more than one scenario.
How can a Credit Intermediary help?
Meaningful comparison requires aligning the loan amount, term, rate structure, insurance and linked products. A Credit Intermediary can help assess affordability, prepare a free simulation, compare available offers from several banks, explain rate structures, review the ESIS/FINE, APR and total cost, and study a renegotiation or transfer.
At DSIC Seixal Torre da Marinha, the analysis is free and tailored to your circumstances. It does not guarantee approval, savings or specific terms; the final decision belongs to each financial institution and depends on its affordability assessment.
Frequently asked questions
Does an ECB increase change my payment immediately?
Not necessarily. A variable mortgage is usually reset according to the date and frequency in the agreement. A fixed-period rate does not change because of that ECB decision.
Does a 0.25-point ECB increase mean Euribor rises by exactly 0.25 points?
No. Euribor reflects money-market conditions and expectations. It may anticipate decisions and need not move by the same amount or on the same date.
Can I switch from variable to fixed or mixed?
You can request a renegotiation or compare a transfer. Terms depend on the lender, contract and a new assessment, and all costs should be checked.
Is a mortgage transfer always free?
No. A new bank may cover certain expenses, but charges and costs can remain. Compare the APR, total amount payable and all conditions.
Should I repay early or keep my savings?
It depends on the mortgage rate, applicable commission, net return on savings and need for liquidity. Do not exhaust the emergency fund without considering the risk.
Conclusion: prepare the decision instead of trying to predict the market
The June 2026 rate increase brought more uncertainty, but it does not make buying or improving a mortgage impossible. It makes scenario comparison, budget protection and total-cost analysis more important.
