I checked my bank account yesterday and was completely shocked! My savings account, which I rarely use, showed a balance of over negative one hundred euros! I remember having a few dozen euros in it, so how could I end up owing the bank money? It was a total nightmare. I’m posting this to ask if anyone has encountered a similar situation and what on earth is going on.

After calming down, I took a closer look at my statement and found a charge labeled “comisión de mantenimiento,” which is the account maintenance fee. Because the account had been inactive for a long time and the balance fell below the bank’s minimum requirement, the fee was automatically deducted. Since there wasn’t enough money to cover it, the account went into a negative balance. I really want to warn everyone: make sure you close any accounts you don’t use. Otherwise, you might end up unknowingly in debt to the bank like me. It’s a scary thought!
Consequences of a Negative Account Balance
I quickly looked it up online, and in Spain, this situation is called “estar en números rojos” or “descubierto en cuenta” (being in the red/overdrawn). This is a serious matter. The bank will start charging interest on the negative amount, and the rate is usually very high! Besides the interest, which is a different issue from losing a bank passbook, there might also be a penalty fee called “comisión por reclamación de posiciones deudoras.” Simply put, it’s a “fee for debt recovery.” It just adds insult to injury!
I’ve summarized the potential fees to give everyone a heads-up:
| Fee Type | Spanish Term | Description |
| Overdraft Interest | Intereses deudores / por descubierto | Calculated daily, the interest rate is typically very high, far exceeding standard loan rates. |
| Debt Recovery Fee | Comisión por reclamación de posiciones deudoras | A fixed fee charged by the bank for notifying you about the debt. |
| Maintenance Fee | Comisión de mantenimiento | The standard account management fee, which can lead to an insufficient balance. |
What Should I Do Now?
Seeing all this, I plan to go to the bank branch first thing tomorrow morning to sort this out. The first step is definitely to pay off the debt to stop any more interest and penalties from accumulating. Then, I’ll talk to the bank staff to see if they can waive some of the penalty fees, as it was a genuine mistake—I just forgot about this account. Finally, if the conversation goes well, I will close this unused account on the spot to prevent any future trouble! I hope my experience serves as a reminder to everyone: check all your bank accounts regularly, and don’t let a dormant account become a debt trap! Does anyone have any other good advice? Or any success stories about negotiating with the bank?
