Best Forex Brokers in Spain for 2026

Spain gives retail investors one striking advantage: FOGAIN, the compensation fund for clients of Spanish investment firms, covers up to €100,000 – five times the EU minimum. The catch is that most forex and CFD trading by Spanish residents takes place with brokers licensed elsewhere, typically in Cyprus, Germany or Ireland, whose clients are protected by their home schemes instead. Add the CNMV's specific warnings on CFDs, a progressive savings-tax scale and the Modelo 720 regime for assets held abroad, and the brand name on the app matters far less than the company named in your contract.

This page is for Spanish residents, including foreigners resident in Spain with an NIE, who want to trade currencies or CFDs through a firm properly authorised to serve them. Our review therefore begins with the contract: which company, licensed where, would take on a client living in Spain, and would FOGAIN or a foreign fund stand behind it? We also assessed Spanish-language service and documentation, whether the broker's data reaches the Agencia Tributaria or you are left to reconstruct every gain for the renta, and the cost of moving euros in and out.

The ranking below applies those checks. Below it, our guide covers the CNMV's rules, tax, costs and the chiringuitos that target Spanish savers.

#¿Es legal? How the CNMV regulates forex and CFDs

The CNMV supervises securities markets and investment firms (empresas de servicios de inversión); the Banco de España supervises banks. Both keep public registers, and the CNMV's includes EU firms that have passported their licence into Spain, either cross-border or through a Spanish branch (sucursal).

Spain has added its own layer on top of the EU's CFD rules. Since 2019 the CNMV has required brokers to warn Spanish retail clients explicitly that a CFD is a complex product that may not be appropriate for them, with an extra warning when leverage exceeds 10:1. Its advertising rules for investment products (Circular 2/2020) also require balanced risk information in promotional material. The CNMV publishes warnings about unauthorised entities – known locally as chiringuitos financieros.

For how cross-border licences work, see our guide to MiFID passporting.

#FOGAIN's €100,000 – and why it may not apply to you

A branch with a Madrid address and Spanish-speaking staff is still part of the foreign company, so FOGAIN does not apply. Compensation is also a last resort: segregation of client money comes first, and no scheme reimburses trading losses. For a trader keeping, say, €5,000 of margin with a broker, the difference is academic; for someone holding larger sums, it is worth thinking about. Our guide to investor compensation schemes compares the limits across Europe.

#Choosing a broker from Spain

What to weigh, roughly in order:

• Entity and protection – as above.
• Spanish-language service from people who understand Spanish tax and reporting, not just a translated website. Support in Catalan, Basque or Galician is rare.
• Tax information. Spanish brokers report to the Agencia Tributaria and many of your figures appear in the draft return; foreign brokers issue an annual statement you must work from.
• Funding. SEPA transfers are the standard and increasingly instant. Bizum is everywhere for person-to-person payments in Spain, but few brokers accept it for deposits; expect bank transfer or card.
• Product scope. Domestic firms such as Renta 4 Banco and Bankinter have long served active Spanish investors in shares, funds and listed derivatives; MyInvestor focuses on low-cost funds. For spot forex and CFDs, most Spanish residents use international firms – XTB, IG and Interactive Brokers are well known in Spain – so check their Spanish entity or registration carefully.

#Spanish firm or international specialist?

The honest answer for most active currency traders is a combination. Spanish banks and investment firms win on protection, tax convenience and the comfort of a local complaints route: the CNMV's complaints service handles claims about firms under its supervision, and Spanish-licensed firms must have a customer-service department that answers you in Spanish. International specialists usually win on the breadth of currency pairs, execution tools, platforms such as MetaTrader, cTrader or TradingView, and pricing on raw-spread accounts.

Many Spanish residents therefore keep long-term savings at a Spanish entity and open a separate, modestly funded trading account with a passported broker. If you do, treat the trading account as risk capital, keep records from day one, and remember that it may count towards the Modelo 720 threshold together with any other foreign holdings.

#Hacienda and your trading gains

Forex and CFD gains are part of the base del ahorro, the savings tax base, taxed progressively:

Practical points:

• Losses. Net capital losses in the savings base can generally be set against other savings income within limits and carried forward for four years.
• Foreign brokers. They do not withhold Spanish tax or feed data into your draft return. You enter gains in your annual IRPF return, converting foreign-currency results into euros.
• Modelo 720. If foreign accounts or securities exceed €50,000 in a category, an informative return is due. The EU Court of Justice found the old penalty regime disproportionate in 2022, but the obligation stands. Crypto held abroad has its own return, Modelo 721.

The Agencia Tributaria is the authoritative source; our European tax overview compares Spain with other countries. General information only, not tax advice – a gestor or asesor fiscal can check your situation.

#Costs worth adding up

Advertised spreads tell only part of the story. Before choosing, estimate:

1. Round-turn cost on your usual instrument: spread plus any commission, at the time of day you trade.
2. Overnight financing for positions held several days – the daily swap on a leveraged position quickly exceeds the spread.
3. Conversion charges when trading instruments priced in dollars or pounds from a euro account.
4. Inactivity and withdrawal fees, which some CFD brokers apply after a few months.

Our trading cost calculator makes the comparison concrete. Keep in mind that costs are also tax-relevant: commissions and financing charges generally reduce the taxable gain, so a broker whose annual statement itemises them clearly will save you time when the renta season arrives in spring.

#Leverage, the CNMV warning and professional status

Retail clients get the EU caps: 30:1 on major currency pairs and lower ratios elsewhere, as detailed in our ESMA leverage guide. In practice, a €10,000 position in EUR/USD ties up about €333 of margin at 30:1 – and a move of little more than 3% against you would erase that margin entirely. The margin calculator shows the figures for any instrument. The ESMA package also forces the broker to start closing positions once your equity falls to half the required margin. For index traders there is a Spanish twist: ESMA classifies the IBEX 35 as a non-major index, which means retail CFDs on it carry a 10:1 ceiling – half the 20:1 available on the Euro Stoxx 50 or the S&P 500. Traders used to the IBEX sometimes discover this only when a position needs twice the margin they expected. Most retail CFD accounts lose money, which is why each broker must publish its own loss percentage. You can ask to be treated as a professional client if you meet two of three criteria – significant trading volume over the past year, a portfolio above €500,000, or relevant professional experience – but you give up negative balance protection and other safeguards. See retail vs professional clients.

#Chiringuitos, clones and recovery scams

The CNMV updates its warning lists constantly, because the model is cheap to run: a polished website, Spanish-speaking call-centre agents and adverts on social networks. Look out for:

• promises of fixed monthly returns from "forex robots" or "AI trading";
• pressure to install remote-desktop software "to help you trade";
• websites imitating authorised brokers, sometimes quoting a real CNMV registration number;
• "abogados" or agencies offering to recover lost money for an advance fee.

If you have already paid a chiringuito, stop all further transfers, ask your bank whether any payment can be recalled, and report the matter to the Policía Nacional or Guardia Civil as well as to the CNMV. Keep every email, chat message and receipt. Expect follow-up calls from people claiming they can recover your money – they are usually part of the same fraud.

#Opening an account from Spain: paso a paso

1. Confirm the entity on the CNMV register.
2. Upload your DNI, or passport and NIE if you are a foreign resident, plus proof of address.
3. Give your Spanish tax number for automatic exchange of tax information.
4. Complete the appropriateness test; expect the CNMV's CFD warning on screen.
5. Fund by SEPA transfer from an account in your own name.
6. From the first month, save statements showing deposits, withdrawals, commissions and financing charges. When you come to complete the IRPF return – or a Modelo 720 check at year end – a complete archive is far easier than asking a foreign broker for historical documents after the account is closed.

#Long-term alternatives to trading

For building savings rather than speculating, Spain has an unusual advantage: switching between investment funds (traspaso) does not trigger tax until you finally cash out. That is why index-fund platforms such as Indexa Capital and funds at MyInvestor are popular. Pension plans (planes de pensiones) offer tax relief on contributions within annual limits, although the money is normally locked up until retirement. For most long-term savers, broad and low-cost funds held for many years are the more usual route than leveraged short-term trading. Our guide to ETF and fund savings plans explains the options.
