Courses : Intermediate Macroeconomics Lecturer : Frischa Adellia Semester : 4th Semester, 2022/2023 Sesion Monetary Policy Monetary policy is an action taken by a country's central bank to influence the money supply in the economy. The goal is to achieve price stability, steady economic growth, and create jobs. Monetary policy is very important in maintaining the economic stability of a country. The central bank is responsible for regulating the supply of money and interest rates in the economy. There are several tools used by central banks to control the supply of money, such as interest rates, cash reserves and open market operations. 1. Interest rate Interest rates are the fees for borrowing money from banks. The central bank can set high or low interest rates, depending on the current economic situation. High interest rates can suppress inflation because it encourages people to save money rather than borrow and spend it. Conversely, low interest rates can encourage consumption and investment, which can spur economic growth. 2. Cash reserves The central bank can set cash reserve requirements that must be met by banks in borrowing money. This requirement aims to limit the amount of money that can be borrowed and to ensure the stability of the banking system. 3. Open market operations Central banks can buy or sell government bonds to influence the supply of money in the market. If the central bank buys government bonds, more money will circulate in the market, while if the central bank sells government bonds, less money will circulate in the market. In addition to these tools, central banks can also use negative interest rate policies, i.e. setting interest rates lower than zero, which aims to encourage banks to borrow money and invest the money instead of saving it. Monetary policy can also be used to control a country's currency exchange rate. However, monetary policy also has some drawbacks. For example, lower interest rates can encourage people to borrow more money and increase the risk of a financial crisis. In addition, global economic uncertainty can affect the effectiveness of a country's monetary policy. Although monetary policy has several advantages in overcoming economic problems, it also has several weaknesses that need attention, including: 1. Cannot solve structural problems: Monetary policy can only solve short-term economic problems and cannot solve structural problems in the long term. Structural problems such as income inequality, structural unemployment and trade imbalances cannot be overcome by monetary policy. 2. Effectiveness limitations: The effectiveness of monetary policy depends on how responsive society and economic actors are to the policy. If the public and economic actors do not respond to monetary policy, the policy will not be successful. 3. Side effects: Monetary policy can also have side effects, such as inflation and changes in currency exchange rates. If the central bank raises interest rates too high, it can slow down economic growth and cause a recession. 4. Political influence: Monetary policy is often influenced by political factors. Politicians and government officials can influence central banks to make policies that support their political goals, not larger economic goals. 5. Creates uncertainty: Uncertainty can be created when a central bank changes monetary policy too frequently or inconsistently. This can affect the confidence of the public and economic actors, and make it difficult for them to plan long-term investments. Because of these weaknesses, monetary policy must be used wisely and in coordination with fiscal and other policies. Therefore, monetary policy must be part of a more comprehensive economic strategy and not be relied upon as the only solution to address economic problems. Monetary policy also needs to be integrated with fiscal policy, which involves regulating government revenues and spending. The success of monetary policy depends on good coordination with fiscal and other policies. In some cases, monetary policy must also be adjusted to the global situation. For example, changes in interest rates by the United States central bank can affect the flow of capital to other countries and affect the stability of economies around the world. In addition, monetary policy can also affect a country's trade balance. If the central bank lowers interest rates, the exchange rate of the domestic currency will decrease, making imported goods more expensive and reducing exports. Therefore, the central bank must pay attention to the impact of monetary policy on the trade balance. Monetary policy must also be transparent and predictable to the public and economic actors. This can help drive greater public confidence and economic stability. Central banks must also be able to evaluate their monetary policy on a regular basis and make adjustments if necessary. In conclusion, monetary policy is one of the most important tools in maintaining a country's economic stability. The central bank must consider the current economic situation, coordination with fiscal policy, and global effects in making effective monetary policy. Central banks must also be transparent and predictable to maintain greater public confidence and economic stability.
