Pros and cons

Pros

  • Trading runs on a commission free model and each stock trade costs $0, so frequent dealing adds nothing to the bill.
  • The listed markets are stocks, etfs and funds, which covers the usual exchange traded assets plus crypto in the same account.
  • The credit card has an annual fee of BRL 0 with cashback on all purchases, and runs on the mastercard network.

Cons

  • Support runs on phone and help centre only, so live chat and email are not among the listed routes.
  • Crypto sits alongside the other markets, and across the brokers compared here 70.15% of retail accounts lose money.
  • The provider is a Brazilian bank, Banco Inter S.A., so the deposit, account fee and rules are denominated in Brazilian reais.

Who it suits

  • Brazilian investors who want stocks, ETFs, funds, bonds and crypto in a single app.
  • People who bank with the same provider and want a card paying cashback on all purchases next to the brokerage.
  • Newcomers to investing, since the minimum deposit is BRL 0 and the model is commission free.

Who should look elsewhere

  • Anyone wanting a euro account with a stated opening deposit, since bunq requires €10.
  • Traders after forex or derivatives, since the markets listed here are stocks, etfs and funds and CFI asks for $0 to start.

Frequently asked questions

What does it cost to open a Banco Inter account?+

The minimum deposit is BRL 0 and the account fee is BRL 0, with a monthly fee of BRL 0 on the banking side. The brokerage is separate from that and runs on a commission free model, so there is no standing charge for holding it.

How much does it cost to buy a share?+

The stock trade fee is $0, and the published fee schedule describes a commission free model for dealing. Other costs sit elsewhere: an account fee of BRL 0 on the bank side and a currency conversion fee of 0% on the global account card.

What cards come with the account?+

There is a credit card with an annual fee of BRL 0 and cashback on all purchases, and a debit card for the global account on the mastercard network. The currency conversion fee on that account card is 0%, so spending abroad does not carry a conversion charge.

What can I trade, and where?+

The listed markets are stocks, etfs and funds, with crypto also named as a feature. All of it runs in the same place: the platform list shows the Super App, and a mobile app is listed as a feature.

Who runs Banco Inter?+

The legal entity behind the brand is Banco Inter S.A., headquartered in Brazil, and the business dates back to 1994. It is a bank as much as a brokerage, which is why current accounts, cards and investments sit in the same app.

How do I reach support?+

Support runs on phone and help centre, so a phone line and a help centre are the listed routes to Banco Inter. Anyone who relies on live chat or email for questions will not find either among the stated channels.

How much do retail investors typically lose?+

Across the brokers compared here, the median share of retail accounts that lose money is 70.15%, with 40.3% at the low end and 88% at the high end. A commission-free model does not move that figure.

How does it rank on cost?+

It sits at 1 of 142 brands on account fee, 1 of 166 on stock trade fee, and 1 of 218 on minimum deposit. The overall score stands at 7.3, and cost is the axis it is ranked on here.
