Mixed-rate contracts accounted for 87% of all new home mortgages in Portugal, according to Bank of Portugal (Banco de Portugal) data cited by DECO PROteste. The contracts offer an initial fixed payment period with an average interest rate of 2.86%, below the 3.23% average for variable-rate loans. Consumer protection specialists warned that while aggressive bank promotions offer short-term savings, borrowers should carefully evaluate how payments will adjust once the variable phase starts.

Context & Explainers
Deco Proteste is Portugal's largest consumer rights organization, providing independent product testing, legal advice, dispute mediation, and advocacy on behalf of consumers. It is part of the international Euroconsumers group.
Deco publishes comparative tests of products and services (from insurance policies to supermarket prices), lobbies for consumer-friendly legislation, and runs a mediation service that helps resolve disputes between consumers and companies. It also operates helplines during crises — such as severe weather events — to advise on insurance claims, billing disputes, and emergency consumer rights.
Membership is paid, but Deco's public advocacy and media presence make it a significant voice in Portuguese consumer affairs. Its studies and reports are frequently cited in news coverage of cost-of-living, energy prices, and financial products.
Banco de Portugal is Portugal's central bank, founded in 1846. It is a member of the European System of Central Banks (ESCB) and the Eurosystem, working alongside the European Central Bank (ECB) to implement monetary policy in the euro area.
Its main functions include supervising banks and financial institutions, ensuring financial stability, managing Portugal's gold and foreign currency reserves, and producing economic research and statistics. It also operates the payment systems infrastructure and issues banknotes.
Banco de Portugal is led by a Governor — currently Mário Centeno (since 2020) — who also sits on the ECB's Governing Council. For residents, the central bank matters because it regulates the banks they use, sets macroprudential rules (such as mortgage lending limits), and provides a complaints mechanism for banking disputes.
