Q & A

How do banks earn money from their clients?

Banks earn money by offering loans to clients and charging interest. A classic example is credit card payments where clients are encouraged to make partial payments or minimum payments, leading to high interest charges.

What is a common mistake people make with credit card payments?

People often think it's better to pay the minimum or to split the bill into installments without considering the high interest rates charged by the bank, which can lead to debt.

What are 'deficit agents' in an economy?

Deficit agents are individuals or entities that spend more than they earn and often take out loans or use overdraft services, getting into debt with banks.

What are 'surplus agents' in an economy?

Surplus agents are those who spend less than they earn, saving or investing their money in various assets that generate returns.

Why is leaving money in a checking account not a good option in Brazil?

Leaving money in a checking account leads to a loss of purchasing power due to inflation over time. The value of the money diminishes, making it a poor option for savings.

What is the fractional reserve banking system?

Fractional reserve banking is a system where banks hold a fraction (typically 10%) of deposited funds in reserve while lending out the remaining 90%. This allows banks to multiply money in the economy.

What happens when everyone tries to withdraw money from a bank simultaneously?

If everyone tried to withdraw their money at the same time, the bank wouldn't have enough to cover all withdrawals, as much of the money is lent out to other clients.

What is the 'spread' in banking terms?

The 'spread' refers to the difference between the interest banks pay to those who invest money (like in a savings account or CDB) and the much higher interest rates they charge on loans.

How can an individual benefit from being a 'surplus agent'?

A surplus agent can benefit by investing in assets such as CDBs, stocks, or real estate funds. These investments generate returns, allowing them to grow their wealth over time.

Why do banks always make money, regardless of whether you have debts or investments?

Banks make money by lending out the funds deposited with them at much higher interest rates than they pay to depositors. They profit from this difference, regardless of whether you are in debt or investing.
