Our verdict
C6 Bank suits Brazilian customers who want a free multi-currency account and a Mastercard debit card. The monthly fee of BRL 0 keeps account running costs at nothing, while a currency conversion fee of 2% makes it a weaker pick for people who convert often.

Pros and cons
Pros
- Monthly fee of BRL 0, so holding the account costs nothing in regular charges.
- Multi-currency and travel are the listed features, multi currency and travel, which suit spending and holding across currencies.
- Supervised by the Central Bank of Brazil.
- A debit card on mastercard covers everyday spending.
Cons
- Currency conversion of 2% sits above the 1% median across the brands compared here.
- The conversion ranking of 151 out of 237 brands is the weak point in an otherwise free cost profile.
Who it suits
- Brazilian customers who want an account with a monthly fee of BRL 0.
- Travellers and multi-currency users, given the features listed as multi currency and travel.
- Card shoppers who want a debit card on mastercard and do not convert currency often.
Who should look elsewhere
- Heavy converters, since 2% applies on conversion, so Wise is worth checking for frequent multi-currency spending.
- Anyone after a free account from a different provider: Monzo Flex has a monthly fee of £0.
- Bitpanda, at a monthly fee of €0, is the other free-footing option to weigh.
Where it sits among rivals
On monthly fee, C6 Bank ranks 1 of 379, close to the front of the table. On currency conversion it sits at 151 of 237, much further down, so the free side of the cost picture wins and the conversion side does not.

Frequently asked questions
What does C6 Bank cost to hold each month?+
The monthly fee is BRL 0, so holding the account costs nothing in regular charges. C6 Bank ranks 1 of 379 on this measure. The cost to watch sits elsewhere, on currency conversion.
What is the currency conversion fee?+
C6 Bank charges 2% on currency conversion. That is above the 1% median across the brands on this comparison, and it is the reason the brand ranks 151 of 237 on this cost. Paying in Brazilian reais keeps that charge out of the picture.
What kind of card does C6 Bank issue?+
It is a debit card running on mastercard, so spending draws on the account balance rather than a credit line. The multi-currency and travel features, multi currency and travel, are built around how that card is used day to day and abroad.
Who regulates C6 Bank?+
C6 Bank is licensed and supervised by the Central Bank of Brazil, and the bank sits in BR under the legal name Banco C6 SA. That regulator is the body to approach with a question about the account itself or the money held in it.
Does C6 Bank support multiple currencies?+
Multi-currency support is part of the listed feature set, multi currency and travel, so the account is built for holding and using currencies beyond Brazilian reais. The trade-off is that converting carries 2%, so the feature earns its keep when balances stay in the currency actually spent.
When was C6 Bank founded and who runs it?+
C6 Bank was founded in 2018 and operates as Banco C6 SA from BR. It is a bank rather than an exchange or wallet, so the account is a deposit account with a card attached, and the Central Bank of Brazil is the regulator on its licence.
How does the monthly fee compare with alternatives?+
Monzo Flex, Wise and Bitpanda also list a monthly fee of £0, £0 and €0 respectively, so none of them charges a monthly fee either. C6 Bank ranks 1 of 379 here, and the 2% conversion charge is what tells the providers apart.
