What is the Estonian DGF?
Estonia is a member of the European Union, and its Deposit Guarantee Fund (Tagatisfond) protects deposits up to €100,000 per depositor per bank, in line with European Directive 2014/49/EU. Estonia has one of the most digital economies in Europe and a well-regulated financial system (supervised by Finantsinspektsioon).
Bigbank vs. the competition in Spain
| Bank | 12-Month Deposit | Country | Minimum |
|---|---|---|---|
| Mano Bank (Raisin) | 2.94% | Lithuania | €1,000 |
| SME Bank (Raisin) | 2.89% | Latvia | €1,000 |
| EVO Bank | 2.85% | Spain | €1 |
| Bigbank | 2.50% | Estonia | €1,000 |
| Pibank | 2.12% | Spain | €1 |
Bigbank at 2.50% is competitive but not the best in its category. If you’re looking for the highest returns via European platforms, Mano Bank (Raisin) at 2.94% or EVO Banco (Spain) at 2.85% are better options.
Why choose Bigbank?
- Direct presence in Spain: you don’t need to use Raisin as an intermediary — direct access via bigbank.es
- Own platform: 100% online management, no intermediary fees
- Long-term deposits: the 2.60% rate over 24 months is attractive for those who want to lock in a rate for a longer term
- EU-regulated bank: same protection as any European bank
Is Bigbank safe for a Spanish saver?
Yes, up to the €100,000 limit. The Estonian Deposit Guarantee Fund (FGD) offers the same protection as the Spanish or German funds. Estonia has a well-capitalized banking sector and an economy with low public debt.
For very large amounts, consider diversifying across several banks: Bigbank for part of the money, EVO Banco for another part, and the rest in liquid interest-bearing accounts.
