What is CDI and Why You Hear About It So Much?

What is CDI?

CDI stands for Interbank Deposit Certificate. It is an interest rate that banks use to lend money to each other. In other words, it is an important reference for the financial market, being one of the main interest rates in Brazil.

When you hear that an investment yields "X% of CDI", it means that the yield of that investment is linked to this rate, which can vary over time.

How does CDI work?

CDI is calculated daily and reflects the average interest rates of loans between banks. For example, if the annual CDI is 13%, it means that, on average, banks are lending money to each other at that rate.

To have a clearer idea: if you have an investment that yields 100% of CDI, and the CDI is at 13%, your investment will also yield 13% per year.

Why do investments yield "X% of CDI"?

Investments linked to CDI are quite common, especially in fixed income products such as CDBs, LCIs, and mutual funds. This happens because CDI serves as a safe reference for investors. When a financial product promises a yield of, for example, 110% of CDI, it is offering a return higher than the interbank market average.

Let’s look at a practical example: if you invest R$ 10,000 in a CDB that yields 110% of CDI, and the CDI is at 13%, your yield will be:

• CDI Yield: 13% of R$ 10,000 = R$ 1,300
• CDB Yield: 110% of CDI = R$ 1,300 * 1.10 = R$ 1,430

Therefore, at the end of the year, your total investment would be R$ 11,430.

How does CDI impact your money?

CDI is a crucial indicator for investors because its variation can directly affect the return on your assets. During periods of rising CDI, investments linked to this rate tend to offer higher returns, which can be advantageous.

On the other hand, during periods of falling CDI, returns may also be negatively impacted. Therefore, it is important to keep an eye on the CDI rate and understand how it affects your investments.

Practical tips for investing based on CDI

• Always research: Before investing, check what the current CDI rate is and compare it with the yield of different financial products.
• Consider the risk: Investments that offer yields linked to CDI are generally low-risk. However, always assess the financial institution's solidity.
• Don’t forget about Income Tax: Remember that fixed income yields, such as those linked to CDI, are subject to taxation. This can affect your net return.
