CPF
The Brazilian tax identification number used in most financial relationships. In practice, many banks, brokers and payment flows require it before you can open or fully use an account.
English guide
Brazil banking and investing terms, explained in plain English.
If you live in Brazil and your app says PIX, boleto, liquidez diária, CDI or rendimento líquido, this page gives you the practical meaning before you move money.
This guide is meant to translate the Brazilian financial vocabulary that shows up in banks, brokers and fixed-income screens. It is educational, not legal, tax or investment advice, and rules can vary by institution, product and your residency status.
First words
What do the most common Portuguese terms actually mean?
These are the terms foreigners living in Brazil usually meet first. Knowing them avoids the most common mistakes: paying the wrong way, comparing pre-tax and post-tax returns, or assuming liquidity is faster than it really is.
PIX
Brazil's instant payment rail. It usually works 24/7, settles in seconds and is the default way to move money between people, businesses and your own accounts.
Boleto
A payment slip with a barcode or QR code. It is common for bills, school fees, rent and some brokerage deposits, but confirmation is not always immediate like PIX.
TED and DOC
Older bank transfer methods. TED is still visible in some systems, while DOC is mostly obsolete. If both PIX and TED are available, PIX is usually the simpler everyday option.
IOF
A tax on certain financial transactions. In investments, foreigners often notice it on very short holding periods or on some credit and foreign-exchange transactions.
IR
Short for Imposto de Renda, Brazil's income tax. In many investment products, what matters is whether the quoted return is gross before IR or net after IR.
CDI
A benchmark interbank rate widely used in Brazil. Many fixed-income products are quoted as a percentage of CDI, such as 95% or 110% of CDI.
Liquidez diária
Daily liquidity. It means you can usually request redemption on any business day, but it does not always mean the cash lands instantly in your account.
Carência and vencimento
Carência is a minimum holding or lock-up period. Vencimento is the maturity date. A product can have daily liquidity after the lock-up, or no liquidity until maturity.
How offers are shown
How Brazilian banks and brokers usually describe returns.
Once you move from payments into investing, the wording becomes more technical very quickly. The key is to read the line as a package: benchmark, tax treatment, liquidity and maturity all matter together.
Return language
Gross return, net return and benchmark language.
Rendimento bruto is the return before taxes and fees that still apply. Rendimento líquido is what remains after the applicable deductions. Rentabilidade usually means performance or yield, but you still need to check the base: annual, monthly, daily, fixed rate or percentage of CDI.
You will also see prefixado for a fixed rate, pós-fixado for a floating rate linked to a benchmark such as CDI, and híbrido for structures that combine inflation plus a fixed spread.
Product names
The fixed-income names you are most likely to meet.
CDB is a bank deposit instrument and is typically taxable. LCI and LCA are bank credit letters that are often marketed with income-tax exemption for eligible investors. Tesouro Direto refers to Brazilian government bonds sold through the retail platform.
Fundo DI is a low-volatility fund that usually follows the CDI universe. In funds, you may also see cota for fund share price, resgate for redemption, cotização for the date your redemption is priced, and liquidação for when the cash is actually credited.
Common questions
Questions foreigners living in Brazil usually have first.
These are the practical doubts that come up before the more advanced decisions. The answer is often less about a single number and more about understanding the system vocabulary.
- Do I need a CPF to open a bank or brokerage account? In most real-world cases, yes. Some institutions may let you start a registration flow without it, but full access to banking and investment products usually depends on CPF validation.
- Is PIX the same thing as a wire transfer? No. PIX is Brazil's real-time payment infrastructure. A traditional wire is closer to TED, which is older, more limited and less central to everyday banking now.
- Why does one product show a gross rate and another show a net rate? Because tax treatment differs across products. You should only compare returns after translating them to the same tax basis and the same time basis.
- Does daily liquidity mean I can always use the money immediately? Not necessarily. It usually means redemption requests are allowed every business day, but settlement timing can still be same day, next day or later depending on the product.
- Why is everything quoted as a percentage of CDI? Because CDI is a common benchmark in Brazilian fixed income. It gives the market a shared reference, but you still need to inspect taxes, maturity and issuer risk before comparing products.
Mistakes to avoid
The main mistakes that happen when the Portuguese labels are not clear.
Most errors are not complex. They usually happen because two products look similar on screen but are described with different tax or liquidity assumptions.
Comparing gross to net
If one screen shows a taxable gross return and the other shows an income-tax-exempt yield, the comparison is incomplete until both are on the same basis.
Ignoring the timing words
Liquidez diária, carência, cotização and liquidação can change when you actually receive cash. Those words matter as much as the headline rate.
Forgetting cross-border tax reality
A Brazilian bank statement may be only one part of your tax story. If you report in another country too, local classification and reporting can differ from the Brazilian label on screen.
