When I first arrived in Spain, I was completely clueless about the banking system here. I just naively left my money in a current account, which earned basically zero interest. Recently, having saved up some spare cash, I decided I couldn’t just let it sit there and be eroded by inflation. So, I started looking into fixed-term deposits and high-yield savings accounts from various banks. After some research, I realized it’s quite a rabbit hole, and I’d like to share what I’ve found.
Traditional High Street Banks vs. Online Banks
First, let’s establish a general principle: major traditional banks like Santander, BBVA, and CaixaBank generally offer very low deposit rates, especially for existing customers—sometimes they’re practically negligible. Their advantage lies in having many physical branches and comprehensive services, which makes them feel more ‘reliable’. On the other hand, online banks like ING, N26, and Openbank, thanks to their lower operating costs, can often provide more competitive interest rates to attract customers. Therefore, if your goal is simply to save money and get a higher return, online banks are definitely the way to go.
A Comparison of Recent Interest Rates from Several Banks
I’ve taken the time to compile some publicly available interest rate information I’ve seen recently, including discussions on topics like bank discount rates, and created a table for easy comparison. Please note that bank rates change frequently, and many promotional offers are for new customers only. So, before taking any action, it’s essential to check the latest terms on the bank’s official website or app, similar to how you would research Spanish loan interest rates.
| Bank Name | Product Type | Indicative APY | Notes |
| Openbank | Cuenta de Ahorro | 2.27% for the first year | For new customers, deposit cap applies |
| Sabadell | Cuenta Online | 2.00% for the first year | Also an online account offer |
| ING | Cuenta Naranja | 1.50% | No salary deposit required, quite flexible |
| Trade Republic | Cuenta Remunerada | Up to 4.00% | German-based investment platform, deposits are protected |
| CaixaBank | Depósito | Generally below 1.00% | Requires negotiation at a branch, but don’t get your hopes up |
From the table, it’s clear the differences are quite significant. Emerging platforms like Trade Republic offer very attractive rates, but since it’s essentially an investment app, you should choose based on your own risk appetite.

Don’t Forget About Deposit Guarantees in Spain
When it comes to saving money, security is the top priority. The good news is that in Spain, all banks regulated by the Bank of Spain are part of the Deposit Guarantee Fund. This means that each depositor’s funds are protected up to €100,000 per bank. In other words, even if a bank were to fail, your deposits up to €100,000 would be safe. Therefore, choosing a properly regulated bank carries minimal risk. If it’s a joint account held by a couple, the coverage doubles to €200,000, which is an important factor to consider when comparing Spanish bank interest rates.
If you want to earn some passive income from your savings in Spain, you really need to do your homework. You can’t just toss your money into any old account and forget about it like in the old days. There are many options on the market now, and by spending a little time comparing them, you could earn enough for a nice dinner out by the end of the year. Where do you all usually keep your savings?
