The interest rate is one of the most powerful tools in economic policy. Although it often seems like a distant concept, it directly influences credit, consumption, investment, employment, and even a country's economic growth. In Brazil, the interest rate has always occupied a central position in economic debate, precisely because of its profound effects on the economy and the daily lives of the population.
In this article, you will understand what the interest rate is, how it works in the Brazilian economy, why it tends to be high in the country, and what its impacts are on consumers, businesses, and the government.
What is an interest rate and what is it used for?
The interest rate represents the cost of money over time. In simple terms, it is the price paid to borrow money or the remuneration received by the lender.
In economics, interest rates serve several functions. They influence the level of consumption, stimulate or discourage investment, affect credit, and help control inflation. Therefore, the interest rate is one of the main instruments of economic regulation.
The Basic Interest Rate in Brazil
In Brazil, the main benchmark is the basic interest rate of the economy, defined by the Central Bank. It serves as a parameter for other rates practiced in the market, such as loans, financing, and financial investments.
When the base interest rate rises, credit tends to become more expensive. When it falls, credit tends to become more accessible. This dynamic is used to influence consumption and investment behavior in the economy.
Why Interest Rates Are Used to Control Inflation
One of the main objectives of the interest rate is to control inflation. When prices rise rapidly, the Central Bank can raise interest rates to reduce consumption and the volume of available credit.
With less money circulating, the pressure on prices decreases. This mechanism helps to contain inflation, but it can also slow down the economy if used excessively.
Therefore, setting interest rates requires caution and constant analysis of the economic landscape.
Impact of Interest Rates on Consumption
Interest rates directly influence household consumption. Higher interest rates make installment purchases, financing, and loans more expensive, causing consumers to postpone or reduce spending.
Lower interest rates stimulate consumption because they make credit cheaper and more accessible. This relationship affects sectors such as commerce, industry, and services, impacting job creation.
Effects of Interest Rates on Productive Investment
Companies rely on credit to invest in expansion, modernization, and innovation. When interest rates are high, the cost of financing increases, reducing the incentive for productive investment.
This could limit economic growth in the long term, since less investment means less productive capacity and job creation.
On the other hand, lower interest rates tend to stimulate investment, favoring economic growth.
Interest Rates and Public Debt
Interest rates also directly impact public debt. A significant portion of government debt is tied to interest rates, meaning that high interest rates increase the cost of public borrowing.
This increase could compromise the state budget, reducing resources available for investments in areas such as health, education, and infrastructure.
Therefore, fiscal balance and economic credibility are fundamental to keeping interest rates at lower levels.
High Interest Rates and Social Inequality
The effects of interest rates are not distributed equally across society. High interest rates tend to disproportionately harm low-income families, who rely on credit for basic consumption and face greater difficulties accessing financing.
At the same time, people with higher incomes and access to financial investments can benefit from high interest rates through higher returns.
This dynamic can contribute to increased social inequality.
The History of Interest Rates in Brazil
Brazil has a history of high interest rates, influenced by factors such as persistent inflation, fiscal instability, and distrust among economic agents.
Over the years, institutional advances have helped to gradually reduce this level, but the country still faces challenges in maintaining structurally lower interest rates.
Relationship Between Interest Rates, Exchange Rates and Foreign Capital
Interest rates also influence exchange rates and the inflow of foreign capital. Higher interest rates tend to attract international investors seeking profitability, which can strengthen the local currency.
However, this inflow of capital can be volatile, increasing the economy's vulnerability to external shocks.
Interest Rates and Economic Expectations
Market expectations play a key role in determining interest rates. If there is distrust regarding inflation or public finances, the tendency is for interest rates to remain high to compensate for risks.
Therefore, clear communication from economic authorities is essential to align expectations and ensure stability.
Challenges in Determining Interest Rates
Determining the ideal interest rate is one of the greatest challenges in economic policy. Interest rates that are too high can stifle growth, while interest rates that are too low can generate inflation and instability.
Finding the balance requires careful analysis of economic indicators and a long-term perspective.
Conclusion
The interest rate is a central instrument of the Brazilian economy, with profound effects on consumption, investment, inflation, and economic growth. While necessary to ensure stability, its use requires balance to avoid negative impacts on society.
Understanding how interest rates work helps citizens comprehend economic decisions and their impact on daily life, from the cost of credit to job opportunities and career growth.
