Lately, leaving spare cash in the bank feels like a losing game. With inflation so high, the interest on current accounts is virtually non-existent. I’ve noticed many friends are starting to look into fixed-term deposits in Spain, so I did some research myself. I’m sharing what I found to see how Spanish fixed-term deposits can help our euros grow a little.
What to Consider Before Depositing?
Before choosing a bank, I think there are a few things to consider:
- Deposit Term: How long do you plan to lock away this money? 3 months, 6 months, 1 year, or longer? Generally, the longer the term, the higher the interest rate, but the lower the flexibility.
- Bank Type: Should you choose a traditional brick-and-mortar bank that we use daily, or an online-only digital bank? The latter usually offers higher interest rates, but some people might feel less secure without physical branches.
- Minimum Deposit: Some high-interest products have a minimum deposit requirement, for instance, requiring at least €10,000. You’ll need to see if your funds meet the criteria.
Comparing Interest Rates from Different Banks
I looked up some recent data on Spanish fixed-term deposits and put together a simple table for comparison. Please note, these rates can change at any time, so always double-check on the bank’s official website before making a decision!
| Bank | Deposit Term | Annual Interest Rate | Notes |
| MyInvestor | 3 Months | 3.00% | Online bank, easy to manage |
| Renault Bank | 24 Months | 3.44% | Part of Renault Group, protected by FGD |
| Banca March | 12 Months | 2.50% | A relatively stable private bank |
| Wizink | 12 Months | 3.00% | Specializes in credit cards and savings products |
As you can see from the table, digital banks are generally much more generous with interest rates than traditional major banks. For regular customers, fixed-term products from banks like Santander or BBVA might offer less than 1%, which is hardly impressive.

Besides bank deposits, Spanish Treasury Bills (Letras del Tesoro) are also very popular right now. This is equivalent to lending money directly to the government, so the risk is extremely low, and the interest rates are very competitive, having even exceeded 3.5% previously. The purchasing process is slightly more complex than a bank deposit and needs to be done through the Bank of Spain’s website or an authorized financial institution. For risk-averse investors, this is an excellent choice, even safer than a bank deposit.
If you have some spare cash that you won’t need in the short term and don’t want to take on much risk, you should consider high-interest fixed-term deposits from online banks or look into Treasury Bills. Don’t let your money just sit idle in a current account—every bit of interest counts! I hope this post is helpful, and feel free to share any banks with even better interest rates you’ve found!
