What is Spread Bancário?
The spread bancário is one of the main sources of profit for banks. It is calculated as the difference between the interest rate that the bank pays to borrow money (capture rate) and the interest rate that the bank charges to lend the same money (loan rate).
How does Spread Bancário work?
Imagine you deposit $270 (approximately R$ 1,000) into a savings account. The bank may pay an interest rate of 0.5% per month for you to have the money there. This means the bank will pay $1.35 in interest per month (0.5% of $270). Now, imagine the bank lends this same money to someone else, charging an interest rate of 2.0% per month. The bank will make $5.40 in interest per month (2.0% of $270). The difference between these two rates is the spread bancário, which in this case is 1.5% (2.0% - 0.5%).
Practical Examples
Let’s consider some examples to better understand how the spread bancário works:
- Example 1: You deposit $1,350 (approximately R$ 5,000) into a savings account with an interest rate of 0.5% per month. The bank pays $6.75 in interest per month. If the bank lends this money to someone else at an interest rate of 2.0% per month, it will make $27.00 in interest per month. The spread bancário is 1.5% (2.0% - 0.5%).
- Example 2: You take out a loan of $2,700 (approximately R$ 10,000) with an interest rate of 3.0% per month. The bank charges $81.00 in interest per month. If the bank paid 1.0% interest to obtain this money, the spread bancário is 2.0% (3.0% - 1.0%).
Comparative Table
The table below illustrates how the spread bancário varies with different interest rates:
| Interest Rate Paid | Interest Rate Charged | Spread Bancário |
|---|---|---|
| 0.5% | 2.0% | 1.5% |
| 1.0% | 3.0% | 2.0% |
| 0.2% | 1.5% | 1.3% |
This table shows how the spread bancário increases when the difference between the interest rate paid and the interest rate charged increases.
Importance of Spread Bancário
The spread bancário is fundamental to understanding how banks profit from financial operations. It helps explain why the interest you pay on a loan is generally higher than the interest you earn on a savings account. Additionally, the spread bancário can vary significantly between different financial institutions, making it important to compare rates before making financial decisions.
