The Tactical Economist

Introduction

Inflation is the continuous increase in the price level of an economy over a certain period of time. It poses significant challenges for economies worldwide, often requiring changes in policy to stabilize markets. In Brazil's case, increased government spending in infrastructure and social benefits has elevated aggregate demand and therefore leading to demand-pull inflation. Therefore, the Monetary Policy Committee (Copom) has raised its Selic interest rate (their primary method at controlling inflation) to 12.25%, aiming to curb inflationary pressures. Interest rates are manipulated through monetary policy which is used by central banks to influence aggregate demand and stabilize the economy.

The rapid increase in consumer spending and investment in Brazil has contributed to an inflationary gap in the economy. This occurs when aggregate demand exceeds aggregate supply at the current price level, leading to upward pressure on prices and economic inefficiency. During these periods, the economy operates beyond its full employment level.

Analysis

Despite the aggregate demand/supply, the price level is at equilibrium in the short-run, and the level of output being at equilibrium, there is a lack of allocative efficiency—a socially optimal situation where resources are maximized. In other words, Brazil's inflationary gap is due to resources exceeding the maximum level of sustainable capacity of full employment in the long-run. This creates an inflationary gap and pressure on the economy. It serves as an indicator that change is necessary to stabilize the economy.

To be able to mitigate the rising inflation, Copom opted for contractionary monetary policy which consists of three tools: Open Market Operations (selling government bonds to reduce the money supply), increasing the reserve ratio (mandating that banks hold more deposits in reserves to reduce the total spending in the economy), and increasing the discount rate (the interest rate the Central Bank charges commercial banks when they borrow from the Central Bank).

By raising interest rates, Copom is able to implement contractionary monetary policy, which aims to reduce aggregate demand and promote the achievement of the economic objectives: low and stable inflation, low unemployment, reduction in business cycle fluctuations, promotion of a stable economic environment for long term growth, and having an external balance. This change in policy also discourages borrowing and spending over time in attempts to slow down economic growth (consumption and investment).

By implementing any one of the three market tools, a change in the market occurs. For example, Copom may have opted for Open Market Operations, producing a decrease in the money supply, followed by an increase in nominal interest rates. Either way, there is a reduction in both quanity supply, and because of it, Brazil's central bank raises the nominal interest rates. Through this, the inflationary gap is able to be corrected. The raised nominal interest rates cause the aggregate demand to decrease due to decreased consumer and investment spending. Due to this, the market is able to stabilize and reach long-run aggregate supply equilibrium (LRAS). Finally, the output gap is closed as full employment is obtained in the long run.

Conclusion

Ultimately, Brazil's contractionary monetary policy is able to reduce inflationary pressures by curbing aggregate demand. This policy helps stabilize the economy by preventing inflation and ensuring that price levels remain through changes in policy. By discouraging excessive borrowing and spending, long-term economic sustainability is able to be promoted as stated before, which is an advantage of contractionary monetary policy. Additionally, this policy can appreciate the currency, as higher interest rates attract foreign investment. These effects are particularly important for Brazil, as rising inflation threatens to hinder consumer purchasing power and economic stability. Furthermore, interest rate changes are flexible and can be easily reversed—as well as gradually incremented in small steps. Monetary policy also has short time lags, no budget deficits, political incentives, or crowding out as opposed to other alternatives like fiscal policy.

However, there are also disadvantages present. One of them being the potential for reduced economic growth. Higher interest rates increase borrowing costs for businesses and households, which encourages lower consumption and investment. This could ultimately result in higher unemployment as businesses lay off workers in response causing conflict between government objectives.
