What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Spanish banks can hold money in currencies other than the euro, usually as a currency account or a currency balance attached to an ordinary euro account, but the terms are set by each bank and are not covered by the EU’s SEPA rules, which apply only to euro payments. Ask for the bank’s pre-contract information on fees, conversion and incoming transfers before you open one.
If you earn in dollars, keep pounds from a UK job, or receive money from a Nigerian domiciliary account, you may not want every payment turned into euros on arrival. The question is whether a Spanish bank will hold that money for you in its own currency, and on what terms. This guide explains how such accounts are usually structured, which rules apply to them in Spain, and what we could and could not confirm in October 2026.
How a currency account works in Spain
A Spanish current account is a euro account. Holding another currency means one of two set-ups, depending on the bank:
- A separate account in the foreign currency, with its own account number, opened alongside your euro account.
- A currency balance inside your euro account, where one IBAN receives the payment and the bank books it to a dollar, pound or other sub-balance instead of converting it.
We could not open a Spanish bank’s own product page for a currency account when we checked in October 2026, so this article names no Spanish bank’s fees. To show what the second set-up looks like in practice, the Italian bank FinecoBank publishes its Multicurrency terms: one IBAN, foreign currency transfers credited to a dedicated balance in that currency, no fixed conversion commission but a spread that varies by currency pair, and the service described as an accessory to the euro current account. A Spanish bank’s terms may differ on every point, which is why the checks below matter.
Which rules apply
SEPA covers euros only
Regulation (EU) No 260/2012, the SEPA regulation, covers credit transfers and direct debits “denominated in euro” within the Union. A dollar or pound payment into a Spanish account falls outside it, so the protections people associate with SEPA, such as euro transfers priced like domestic ones, do not automatically apply. Incoming dollars from Nigeria travel as international (SWIFT) payments, and the Spanish bank’s own tariff decides what it charges to receive them.
Know-your-customer rules apply to every account
Spain’s anti-money-laundering law, Ley 10/2010, requires banks to identify every customer with reliable documents before the relationship starts (article 3), to learn the nature of the customer’s professional or business activity (article 5) and to monitor transactions, including the source of funds, against that profile (article 6). If the bank cannot complete these checks it must not open the account or carry out the transaction (article 7.3). A currency account invites questions because the money usually comes from abroad, so expect to explain where it comes from.
Tax follows you, not the currency
If you are tax resident in Spain, the personal income tax law (Ley 35/2006, article 2) taxes your income wherever it arises. Interest on a dollar balance, and any gain when you later convert, is part of that picture whether the account is in Spain or Nigeria. Accounts held outside Spain can also bring a reporting duty: the Agencia Tributaria’s Modelo 720 is the information return on assets and rights held abroad. A currency account at a Spanish bank is in Spain; a domiciliary account in Lagos is not. Check the Agencia Tributaria’s own guidance on Modelo 720 for the thresholds that apply to you.
What to check before you open one
- Which currencies the bank holds, and whether US dollars and pounds are both available.
- Whether it is a separate account or a balance under your euro IBAN, and which details a Nigerian sender should use.
- The fee to receive an international payment, and whether a correspondent bank may deduct a charge before it arrives.
- How conversion is priced: a stated commission, a spread on the bank’s own rate, or both. Compare the rate shown against the mid-market rate on the same day.
- Any monthly maintenance fee on the currency account, and whether it can be held without a minimum balance.
- Whether a card can spend from the currency balance, or whether every card payment converts from euros.
- How deposits in that currency are treated under Spain’s deposit guarantee scheme, the Fondo de Garantía de Depósitos. Ask the bank to confirm it in writing; we could not confirm the scheme’s treatment of foreign currency deposits from its own pages.
When a currency account makes sense
A currency account helps when you receive money in that currency regularly and spend or send it in the same currency, for example dollars from a Nigerian domiciliary account that you plan to send back for school fees. It helps less when every payment ends up in euros anyway, because you pay to receive the money and then still pay to convert it. If you are weighing dollars against euros for savings, our guide to holding a US dollar account while living in Spain looks at that choice, and receiving naira-origin money in Spain covers the route from a Nigerian account.
Where Pryme fits
A Pryme Personal Account can be opened from Spain and holds NGN, USD, GBP and EUR in one place, with account details for each currency, so money stays in the currency it arrived in until you choose to convert. Swap shows the rate first and the fee on its own line before you approve. Outside Nigeria, Pryme’s activities are carried out through regulated partners; it is not a Spanish bank.

Questions people ask
Can I open a dollar account in Spain as a Nigerian?
Spanish banks set their own eligibility rules. In general you will need to pass the same identity and source-of-funds checks as for a euro account under Ley 10/2010, and the currency account is often attached to a euro account you already hold.
Is a USD transfer into a Spanish account a SEPA transfer?
No. The SEPA regulation covers euro credit transfers and direct debits only. A dollar payment travels as an international transfer, and the receiving bank’s own tariff applies.
Do I declare a Nigerian domiciliary account to Spanish tax?
If you are tax resident in Spain, income from it is taxable in Spain, and accounts held abroad may need to go on the Modelo 720 information return depending on value. Check the Agencia Tributaria’s guidance for the thresholds; this is information, not tax advice.
Will my Spanish bank convert dollars automatically?
It depends on the account. If you only have a euro account, incoming dollars are normally converted. Ask the bank whether a currency balance can receive them unconverted.
