CDB stands for Bank Certificate of Deposit. It is a bond issued by banks that use it to raise funds for credit operations in general.
Thus, by purchasing a CDB, you will be making a kind of "loan" to the bank in exchange for a daily return.
Unlike savings, which have the same yield for all banks, CDB yield varies by institution. You can apply to CDBs offered by your own bank or CDBs from other banks by simply opening an account with a broker.
Income from a CBD today
Yield varies by type of CBD, which are basically three main:
- Post-Fixed CDB: is the most common. Typically, these securities yield a certain percentage of the CDI (Interbank Deposit Certificate) rate per year, today at approximately 4.4%. See some examples in the image below.
CDBs issued by different banks, each offering as a yield a certain percentage of the CDI.
- PREFIXED CDB: The bank sets a predefined rate and during that term you will always receive the agreed-upon fee.
- Hybrid CBD: the profitability is mixed, being a prefixed part and another linked to some financial index, usually inflation (IPCA).
For example, if you purchase a CDB that pays 110% of the CDI, your current annual gross profit would be 110% of 4.4, ie:
4.84% per year
0.403% per month
Taxation and Redemption
The income tax rate (IR) is levied on the profit obtained and varies according to the application term:
- 22.5% for applications up to 180 days
- 20% on 181-360 day applications
- 17.5% on 361 to 720 day applications
- 15% on apps over 720 days
An advantage of the CBD is that the income tax rebate is only made at the time of redemption or application maturity, unlike other investments, such as DI funds, where IR withholding is made every 6 months. (It is the famous "eater", which usually occurs on the last business day of May and November).
As there is no such advance payment of income tax on the CDB, the amounts remain in their application throughout the period, yielding interest, thus increasing their profit at the end.
One thing to be aware of is that not all CDBs have daily liquidity, meaning the investor may have to wait for the grace period to expire. However, in these cases the profitability is usually higher because you are giving up liquidity for higher interest rates.
If you do not know how long you will need the money, it is better to opt for a CDB with daily liquidity. Some of them are progressive, ensuring you daily liquidity, but also providing for increased pay as your investment term grows longer. All this information must be provided by the institution offering the investment.
Note: Try not to redeem your investment before 30 days, to avoid the levying of IOF (Tax on Financial Operations), which is regressive from the 1st to the 30th day of application, zeroing after that period.
Risk and warranty
The application in CDBs is guaranteed by the FGC (Credit Guarantee Fund) up to the limit of R $ 250 thousand by CPF or CNPJ. That is, if the banking institution “breaks down” and runs out of resources to pay the amount invested to the investor, the FGC covers this amount. If you intend to invest more than $ 250,000, it is recommended to split the amount between two or more institutions to reduce the chances of having problems.
