Best fixed-term deposits in 2026

8 min readReviewed By Thorben Rasmus IdelReviewed by Nahar Geva

The best offers pay more than double the market average, but almost all require being a new customer or bringing money in from outside, and none of them lasts: on renewal CGD drops to 0.25% and Santander to 0.01%. We compared CGD, Santander, Banco CTT and ActivoBank in each bank’s official rate leaflet.

Independent: we earn no commission on any product listed on this page. The ranking follows only the criteria below.

Verdict: which to choose

  • Best rate

    3.00% gross over 90 days, the highest rate here, but only for customers who opened an ActivoBank account in the preceding 90 days, and capped at €10,000.

  • Best for larger amounts

    2.50% gross over 12 months and up to €150,000, fifteen times the cap on the best rate: the option for savers with a lot to place, in exchange for €5,000 of new money.

  • Best high rate with a low minimum

    2.50% gross over 12 months from €250, against the €5,000 the other 2.5% offer demands, but only for savers who have never been a CGD customer.

  • Best without a new-money condition

    At 2.500% in September 2026, state-guaranteed, with no new-money condition and from €10: the most flexible alternative to a deposit.

  • Most accessible

    The rate is low (1.00%), but €100 is enough and you can withdraw at any time, useful for a short term without locking up much money.

How we ranked these

The ranking is not the result of any commercial agreement. We verified every rate against the bank’s own official page (several comparison sites publish out-of-date figures) and assessed them against these criteria:

  • Gross rate (TANB): the published gross annual rate, before the 28% tax on interest.
  • Access conditions: does it require "new money"? Is it limited to new customers? What is the minimum?
  • Term and liquidity: how long the money is locked up, and what you lose by withdrawing early.
  • Renewal rate: what the deposit pays once the initial term ends and it rolls over by itself.
  • Protection: Deposit Guarantee Fund cover (€100,000 per depositor per bank) or a State guarantee.
  • Transparency: are the terms published in the product’s official disclosure, without needing a simulation or a salesperson?

  • It renews automatically at the much lower Standard Deposit rate, so you must act once the 90 days are up

Frequently asked questions

What happens to the rate when the deposit renews?
Almost all of these deposits roll over by themselves at the end of the term, and practically none renews at the advertised rate. CGD spells it out in its own rate leaflet: the Depósito Caixa +Valor pays 2.50% for the initial term and 0.25% on the first renewal and every one after it, a tenth of the headline. Santander is starker still: the Depósito Poupança pays 1.05% for the initial term and, on renewal, 0.40% until 30 September 2026 and 0.01% from 1 October 2026. ActivoBank’s Novos Clientes AB deposit renews at the Standard Deposit rate, and Banco CTT’s DP Novos Montantes renews at whatever rate is in the tariff that day. In practice a campaign rate is the return on one term, not a recurring annual return: note the maturity date and decide again then.
Do CGD and Santander pay good deposit rates?
They are two very different cases. CGD has one of the highest rates in this comparison, 2.50% gross over 12 months on the Depósito Caixa +Valor, but reserves it for new personal customers: never having been a CGD customer, or being one with no relationship with the bank, and opening a euro current account from 1 July 2026 with new money. Santander pays 1.05% gross on the Depósito Poupança over 3, 6 or 12 months, with no new-money condition but a €15,000 minimum. All of these figures come from the interest-rate leaflets each bank is required to publish, which are the source for this page.
What is the difference between the gross and net rate?
The TANB (gross annual nominal rate) is the rate before tax, the one banks advertise. Deposit interest is taxed at a flat 28% on the mainland (19.6% in Madeira and the Azores), so the effective return is considerably lower. The best deposit in this comparison shows it plainly: its 3.00% gross rate is 2.16% net, and ActivoBank itself publishes both figures side by side.
Is my money protected?
Bank deposits in Portugal are covered by the Deposit Guarantee Fund up to €100,000 per depositor per bank. Above that, it is worth splitting savings across institutions. Savings certificates are guaranteed directly by the State and are not subject to that ceiling.
What does "new money" mean?
It means money that was not already at that bank: typically it must be transferred in from another institution within a set window (30 days in the cases above) and represent a genuine increase in what you hold there. Moving money between accounts at the same bank does not count: this is how the best rates stay reserved for savings brought in from outside.
Can I withdraw before the term ends?
It depends on the product. Several deposits allow early withdrawal but with total forfeiture of interest on the amount withdrawn: you get your capital back with no return at all. Always confirm this in the standardised information sheet before subscribing.
Savings certificates or a fixed-term deposit?
Savings certificates require no new money, start at €10, carry a State guarantee without the €100,000 ceiling, and earn retention bonuses over the years. In exchange, the rate is reset monthly and capped at 2.50%, whereas a deposit fixes your rate for the whole term. For money you might need to access, certificates are usually more flexible.
