Ideal if you want the tax advantage of switching between funds (no tax when switching from one fund to another).

XTB is Spain’s best-known broker. €0 commission on stocks and ETFs up to €100,000/month in trading volume (€1 per trade thereafter). The savings account with a 3.10% APR for the first 90 days (then 1.55%) is a competitive welcome bonus. Regulated by the CNMV — Spain’s most direct oversight.
Scalable Capital — The best interest-bearing account
Scalable Capital stands out for offering 2.50% APR on the account balance—the highest among all investment platforms in Spain. With the €2.99/month plan, you get unlimited trades. Very popular among investors who do monthly dollar-cost averaging without wanting to pay €1 per trade.
