What is CDI and why do you hear about it so much?

What is CDI?

The Interbank Deposit Certificate (CDI) is an interest rate that represents the cost of money between banks in Brazil. In other words, it’s the rate at which banks lend money to each other. This rate is important because it serves as a reference for various investments in the financial market.

When you hear that an investment yields "X% of CDI", it means that the return of that investment is tied to this rate. For example, if CDI is at 13% per year and an investment fund promises returns of 90% of CDI, it means the fund will yield 11.7% per year.

How does CDI work?

CDI acts as a thermometer for the economy. When the Selic rate, which is the basic interest rate of the economy, increases, the CDI tends to rise as well. This is because, with higher interest rates, banks become more cautious, and the cost of credit increases.

For instance, if CDI is at 13% and you invest R$ 1,000, at the end of a year, if your investment yields 100% of CDI, you will have R$ 1,130. If it yields 90% of CDI, you will have R$ 1,117. This illustrates how CDI directly influences your financial return.

Why do you hear so much about CDI?

The reason why CDI is so frequently mentioned is that it serves as a reference for many investments, especially fixed income ones. CDI acts as a benchmark, meaning it’s a parameter for investors to compare the yields of their investments.

Moreover, many financial products, such as CDIs (Certificates of Deposit) and investment funds, have their returns tied to CDI, making it a central element when deciding where to invest your money.

Impact of CDI on your investments

Understanding how CDI works can help you make more conscious decisions about your investments. Here are some practical tips:

• Compare investments: Whenever you’re considering an investment, see how much it yields in relation to CDI. This will help you understand if you’re making a good deal.
• Consider liquidity: Some investments that yield more than CDI might have long waiting periods. Assess whether you can afford to keep your money tied up for that time.
• Keep an eye on Selic: Follow changes in the Selic rate, as they directly affect CDI and, consequently, your investments.
