10. Monetary Policy

Página 10

Monetary policy is one of the main instruments used by governments and central banks to control a country's economy. It refers to actions that manipulate the amount of money in circulation and the interest rate, with the aim of influencing inflation, economic growth, the level of employment, the exchange rate and the equilibrium of the balance of payments.

There are three main instruments of monetary policy: open market operations, reserve requirements and the rediscount rate. Open market operations involve the buying and selling of government securities by the central bank. When the central bank buys bonds, it injects money into the economy, which lowers interest rates and stimulates consumption and investment. When you sell bonds, you take money out of the economy, raising interest rates and contracting consumption and investment.

Required deposits are a percentage of deposits that banks are required to hold at the central bank. When that rate is raised, banks have less money to lend out, which raises the interest rate and contracts the economy. When the rate is lowered, banks have more money to lend, which lowers the interest rate and stimulates the economy.

The discount rate is the interest rate that the central bank charges banks to lend money. When that rate is raised, banks have less incentive to lend money, which constricts the economy. When the rate is lowered, banks have more incentive to lend money, which stimulates the economy.

Monetary policy can be classified into expansionary and contractionary. Expansive monetary policy is used when the economy is in recession, with high unemployment and low inflation. In this case, the central bank lowers the interest rate and increases the money supply to stimulate consumption and investment. Contractionary monetary policy is used when the economy is overheated, with low unemployment and high inflation. In this case, the central bank raises the interest rate and decreases the money supply to contract consumption and investment.

It is important to note that monetary policy has limitations. For example, it may not be effective in a liquidity trap, when the interest rate is already close to zero and cannot be lowered any further. Also, there can be a trade-off between inflation and unemployment, known as the Phillips curve. This means that a monetary policy that reduces inflation can increase unemployment, and vice versa.

Moreover, monetary policy can have unintended effects. For example, if the central bank raises the interest rate to fight inflation, this could appreciate the exchange rate and hurt exports. Or, if the central bank lowers the interest rate to stimulate the economy, it could depreciate the exchange rate and increase inflation.

Finally, monetary policy must be coordinated with fiscal policy, which refers to the use of the government budget to influence the economy. If the government is spending more than it collects, this can neutralize the effects of contractionary monetary policy. Or, if the government is raising more than it spends, it can counteract the effects of expansive monetary policy.

In conclusion, monetary policy is a powerful tool for controlling the economy, but it must be used carefully and in coordination with other policies. For public procurement candidates, it is essential to understand the concepts and instruments of monetary policy, as well as their implications for the economy.
