The Portugal Central Bank has recorded the 3-month Euribor climbing to 2.351% today, marking the highest level since April 2025 and setting the stage for another round of mortgage payment increases for thousands of borrowers across the country. This uptick comes as markets brace for an anticipated interest rate hike by the European Central Bank (ECB) later this week, the first upward move in nearly three years.
Why This Matters
• Mortgage costs rising: Borrowers with 3-month Euribor-linked variable-rate mortgages will see their monthly payments increase at their next quarterly review.
• ECB meeting Thursday: The ECB is expected to raise benchmark rates by 0.25 percentage points, reversing the cutting cycle that began in June 2024.
• 24.55% of loans affected: Nearly one-quarter of Portugal's variable-rate home loans are tied to the 3-month Euribor, according to April data from the Portugal Central Bank.
The 3-month rate jumped 0.039 points compared to Friday's session, continuing an upward trajectory that began accelerating in recent months. Meanwhile, the 6-month Euribor—the most widely used benchmark in Portugal since January 2024—edged up to 2.586%, while the 12-month tenor dipped slightly to 2.816%.
What This Means for Homeowners
For anyone holding a variable-rate mortgage indexed to the 3-month Euribor, the immediate consequence is straightforward: your next payment will be higher. The rate used to calculate your mortgage installment is typically the monthly average from the month preceding your contract review. With May's monthly average settling at 2.226% and the daily rate now surging past that level, June and July reviews will reflect the sharper increase.
A borrower with a €150,000 loan over 30 years, for instance, could see their monthly payment rise by approximately €20 to €30 depending on their spread—the fixed margin added by the bank. While this might sound modest, it compounds over time and adds to the cumulative financial pressure families have faced since inflation spiked in 2022.
The 6-month Euribor, which accounts for 39.56% of Portugal's outstanding variable-rate home loans, also crept higher, though by a smaller margin of 0.002 points. The 12-month rate, representing 31.53% of the market, bucked the trend and fell by 0.026 points. This divergence reflects market uncertainty ahead of the ECB's policy meeting.
ECB Set to Raise Rates
The policy decision scheduled for Thursday will mark a significant shift in European monetary policy. The ECB is expected to raise its deposit facility rate from 2% to 2.25%, the first increase since September 2023.
Global economic conditions, including persistent inflationary pressures and energy market volatility, have influenced the central bank's decision-making process. Policymakers are determined to maintain price stability and support the eurozone economy. The ECB had previously cut rates eight times starting in June 2024, then held them steady for seven consecutive meetings through April 2026. The anticipated rate increase signals a new phase in monetary policy, with further increases of 0.25 percentage points expected in subsequent meetings, potentially pushing the deposit rate higher through the year.
Market Outlook
Market participants expect the 3-month Euribor to stabilize in the coming months, with movements closely tied to ECB policy decisions and broader economic developments. The trajectory of rates will depend on inflation trends, economic growth, and global financial conditions.
However, these projections hinge on various economic factors and market conditions. Should energy prices remain volatile or global economic uncertainty persist, upward pressure on interest rates could continue into 2027.
Credit Growth in the Portuguese Mortgage Market
Portugal's mortgage market continues to show robust activity. The mortgage market has demonstrated significant expansion, with year-on-year growth reflecting strong demand for housing credit, supported by low unemployment and a relatively stable economic environment. Government-backed guarantee programs have also eased access to credit for borrowers.
Yet credit rating agencies have noted that elevated property prices and construction costs are beginning to strain household payment capacity. In response, the Portugal Central Bank has tightened lending standards, imposing stricter loan-to-income and debt-service-to-income ratios to curb excessive risk-taking by both lenders and borrowers.
Understanding the Euribor Patchwork
The Euribor is not a single rate but a family of benchmarks reflecting different borrowing terms. The 3-month, 6-month, and 12-month rates measure what a panel of 19 eurozone banks charge each other for short-term loans. The key difference for borrowers lies in how often their mortgage rate resets:
• 3-month Euribor: Your rate adjusts every quarter, giving you faster exposure to market shifts—beneficial when rates fall, painful when they rise.
• 6-month Euribor: Revisions occur twice a year, offering a middle ground between responsiveness and stability.
• 12-month Euribor: Annual resets provide the most predictable payment schedule but delay both the benefits of falling rates and the sting of rising ones.
Your mortgage payment is calculated by adding the relevant Euribor rate to your bank's spread—a fixed margin typically ranging from 0.5% to 1.5% depending on your creditworthiness and loan terms.
Managing the Squeeze
For households already stretched by rising living costs, higher Euribor rates pose a challenge. Financial advisers recommend reviewing your mortgage contract to understand your indexation period and considering a switch to a fixed-rate or mixed-rate product if your bank offers competitive terms.
Some lenders are beginning to promote fixed-rate mortgages more aggressively, offering 10-year locks at rates between 3% and 4%, which can provide peace of mind in an uncertain interest rate environment. However, fixed rates typically carry higher spreads and less flexibility for early repayment.
Another strategy is to accelerate debt repayment during periods of lower rates, reducing the principal and thereby limiting the impact of future rate increases. The Portugal Central Bank's new lending rules also encourage borrowers to maintain lower debt-service ratios, which can provide a buffer against payment shocks.
What Comes Next
All eyes are now on Frankfurt. If the ECB follows through with the expected rate hike on Thursday, upward pressure on Euribor rates will intensify, translating into higher mortgage costs for the majority of Portugal's homeowners with variable-rate loans.
The central bank's forward guidance—its signals about future policy moves—will be just as important as the immediate decision. Should policymakers indicate additional tightening ahead, rates could rise further in coming months, compounding the financial burden for borrowers.
For now, the message is clear: if you hold a variable-rate mortgage, prepare for higher payments in the coming months. And if you're considering taking out a loan, factor in the likelihood that rates will remain elevated through the remainder of the year.
