Key takeaways

  • New Treasury Certificates only exceed 3% interest in their tenth year, 2036
  • Government says product targets savers who don't need quick access to cash
  • Early redemption is allowed after just one year, despite that framing
  • Product is part of Portugal's state-backed retail savings options

Portugal’s government has launched a new series of Certificados do Tesouro (Treasury Certificates), a state savings product, but the interest rate only climbs above 3% in the tenth and final year, 2036. The government defends the structure as suited to “savers with less need for liquidity,” even though money can technically be withdrawn after just one year.

How the new Certificados do Tesouro work

Certificados do Tesouro are a way for the Portuguese state to borrow directly from ordinary citizens rather than only from large institutional investors, similar in spirit to the long-running Certificados de Aforro but generally aimed at a different segment of savers with larger sums to invest. Savers effectively lend money to the state in exchange for a return, with the investment backed by the government itself rather than a bank or fund manager.

Under the new terms, the interest rate is structured to rise gradually the longer the money stays invested, back-loading the best returns toward the end of a ten-year term. Someone who commits their savings until 2036 will see the highest payout, while those who withdraw earlier — even after the minimum one-year holding period — receive a much lower return.

Why this matters for foreign residents managing savings in Portugal

For expats, retirees and other foreign residents who have made Portugal their base and are looking for low-risk places to park savings, state-backed products like this are often more attractive than bank deposits because they carry the guarantee of the Portuguese Republic and typically come with no entry or management fees. However, the new structure means the product is far less rewarding for anyone who might need to access their money within the first several years.

Anyone considering this option should weigh their own liquidity needs carefully, since the advertised higher returns are only realistic for savers prepared to lock in their funds for a full decade. Those who value flexibility, or who are unsure about their medium-term plans in Portugal, may find the early-withdrawal returns underwhelming compared with other savings alternatives.
