Monetary policy is a strategy adopted by a national monetary authority aimed at achieving macroeconomic objectives such as high employment and stable prices by influencing financial conditions, which is usually characterized by low and stable inflation rates. This policy is important in maintaining secondary economic status and facilitating the exchange of predetermined currencies with other currencies. In modern times, many central banks in developed countries operate within an inflation targeting framework, while developing countries often follow fixed exchange rate systems. In the 1980s, money supply targeting was a prominent strategy, but it has since fallen out of favor, although it remains the official approach in some emerging economies.
The use of appropriate instrument elements in the implementation of inflation policy depends on a number of factors, such as a country’s development level, institutional framework, traditions, and political structure. Interest rate targeting is the key tool, achieved through direct adjustments to the central bank’s interest rates or indirectly through open market conduct. Interest rates influence economic activity, employment, and inflation through what is collectively known as the monetary ecosystem. Also, communication strategies such as forward guidance and determining reserve requirements are implemented in some countries. Monetary policy may in reality be accommodative, stimulating economic activity, or contractionary, reducing economic activity to reduce inflation and employment.
Inflation policy affects the economy through financial channels such as interest rates, currency rates, and prices of financial transactions. It shows the differences between different currencies through financial investments, as opposed to fiscal policy, which uses taxes to manage business cycle phenomena. In developed countries, inflation policy is generally implemented without fiscal policy, with modern central banks enjoying independence from direct government control and instructions.
The best way to implement inflation policy is a subject of ongoing research and controversy, drawing from monetary economics and various subdisciplines of macroeconomics. Effective inflation implementation is important to promote economic stability and sustainable growth, while minimizing the negative effects of economic downturns.
1. Issuing coins and paper money
Monetary policy has a rich and varied history spanning centuries and continents, the origins of which are disputed among historians, economists, anthropologists, and currency scholars. There is controversy about the exact beginnings of money, but the use of coins is usually traced to early Lydia in the 8th century BC, although some consider it to have even earlier origins in ancient China.
For several centuries, the main focus of monetary policy was on two methods: coin exchange and paper money issuance. The last originated in 7th century China, where coin money was used along with promissory notes known as “jaozi”. However, paper currency became primarily a medium of exchange during the Yuan dynasty. The Yuan government, faced with a shortage of coin for war and governance, resorted to printing paper currency without limits, leading to hyperinflation.
The development of monetary policy also led to the emergence of official currency values linked to gold or silver, whose prices were sponsored by law, although sometimes differing from market rates. Interest rates, now an integral part of monetary policy, were not initially coordinated with other measures and were often seen as an executive decision. Monetary policy has undergone significant changes over the centuries, from early coinage and inflation to the introduction of paper currency and the establishment of official currency values. These developments have shaped economies and societies, leaving ripple effects on global financial systems.
2. Central banks and the gold standard
The establishment of central banks and the adoption of the gold standard played an important role in the development of monetary policy and global finance. The establishment of the Bank of England in 1694, backed by gold reserves, marked the beginning of actionable steps in the development of monetary policy. The main objectives were to maintain the standard of money, ensure that notes could be traded in cash, and prevent currency devaluation through excessive currency compounding. Between 1870 and 1920, industrialized nations established central banking systems, with the Federal Reserve being one of the last banks to emerge in 1913. During this period, central banks played a role of “last resort” and contributed to the impact of the Marginal Revolution in economics.
The objective of central banks under the gold standard was to maintain currency stability and a fixed exchange rate with other gold-backed currencies. For this, constant adjustment was required to keep currency rates stable. Under the gold standard, the value of a national currency was tied to a specific quantity of gold, with governments committing to buy or sell gold at a price determined by the value of the base currency. However, policies to maintain the gold standard may have negative effects on employment and economic activity. This was seen most clearly during the Great Depression of the 1930s, as the gold standard restricted the ability of adherents to implement effective monetary measures to resolve economic conflict. As a result, after World War I many countries abandoned the gold standard in favor of alternative currency structures.
As of now, no country uses the gold standard, which would make it the dominant currency system. It brings an end to the intertemporal period. The transition away from the gold standard acknowledges its limitations and the need for more flexible currency policies to address problem.
3. Fixed exchange rates prevailing
In 1944, the Bretton Woods system was established, creating the International Monetary Fund and implementing a fixed exchange rate system. This system linked the currencies of the most industrialized nations to the United States dollar, which was directly convertible into gold. Over the following decades, this system helped maintain international stable exchange rates. However, in the 1970s, when the United States dollar was considered overvalued, the system faced challenges. In 1971, the dollar ceased to be convertible into gold, signaling a significant change. Attempts to revive fixed exchange rates proved unsuccessful, leading to major currencies beginning to float against each other in 1973. In Europe, similar efforts were made to establish a regional fixed exchange rate system through the European Monetary System. These efforts established the economic and monetary union of the European Union, and introduced the euro currency.
4. Money supply targets
Monetarist economists, notably Milton Friedman, believed that increasing the money supply could have an impact on the business economy. They previously suggested financing government deficits through uniform money creation at arbitrary times instead of stimulating growth. Friedman later suggested consistent, low rates of growth in the money supply to maintain steady output growth and low inflation (Friedman, 1963). During the increase in inflation caused by the energy crisis of the 1970s, central banks, including the U.S. Federal Reserve, adopted a policy of keeping the money supply within reasonable standards to meet money supply targets. However, this approach encountered difficulties. When Federal Reserve Chairman Paul Volcker implemented this policy in 1979, it proved invalid due to the unstable relationship between money flows and macroeconomic quantities (Volcker, 1979). Other countries also encountered problems implementing this policy, leading to a review of the efficacy of direct money supply. Even Friedman acknowledged that the results were less successful than exciting expectations (Friedman, 1992).
5. Inflation targeting
In 1990, New Zealand adopted a significantly benchmarking basis for its monetary policy, which is considered a departure from the usual approaches. The purpose of this strategy was to move the country’s inflation rate towards a predetermined target, thereby shifting the focus to exchange rate stability or currency circulation rates rather than to inflation. Instead, the central bank began using interest rate adjustments to match inflation to a set target. This innovative initiative received wide exposure for its efficacy, inspiring many developed nations to adopt similar measures years later.
However, the global financial crisis of 2008 resulted in questions about the efficacy and flexibility of monetary policies. Economists claimed that many inflation-accommodations had set inflation targets too low, a view that grew in support during the crisis with many monetary concepts facing the zero bound on interest rates. This resulted in many regions experiencing declining inflation rates, with some regions experiencing near-zero or maximum inflation rates. Despite these challenges, by 2023, all G-7 member states accepted inflation-guidance to varying degrees, such as the European Central Bank and the Federal Reserve Bank incorporating its core principles into their monetary policies. In particular, as inflation-guidance became popular, fixed exchange rate regimes were notable in emerging economies, which is believed to reflect diversity among diverse approaches to economic policies.
All types of monetary policy will delve into various theories, historical contexts, and modern practices. In this essay, I will provide an overview of the major types of monetary policy, including traditional and unconventional approaches, their impacts, and efficacy.
Monetary policy refers to actions taken by a central bank to influence the availability and cost of money and credit in an economy, primarily intended to achieve basic economic objectives, such as price stability, full employment. And to achieve economic development. Central banks usually implement monetary policy through certain tools, such as open market operations, discount rate changes, and reserve requirements.
1. Conventional Monetary Policy
Traditional monetary policy involves controlling the amount of money and interest rates using monetary instruments. The major tools used by the central bank under conventional monetary policy include open market operations, discount rates, and reserve requirements.
a. Open Market Operations (OMOS): The central bank buys or sells government securities in the open market by conducting OMOS. When the central bank buys government securities, it injects liquidity into the banking system, thereby lowering interest rates and increasing lending. Conversely, the sale of government securities depletes liquidity, leading to higher interest rates and a reduction in lending.
b. Discount Rate: Discount rate is the interest rate charged by the central bank on borrowing money directly from commercial banks. By adjusting the discount rate, the central bank can influence banks’ cost of borrowing, which further affects lending rates in the economy.
c. Reserve requirements: The central bank can also set composition requirements that require banks to hold funds against their deposits. By changing reserve requirements, the central bank can directly influence how much money banks can borrow, thereby affecting the overall money supply.
2. Unconventional Monetary Policy
Unconventional monetary policy is unusual measures adopted by a central bank in response to a severe economic downturn or financial crisis when conventional policy tools become ineffective or inadequate. These measures are designed to provide additional monetary stimulus and financial stability.
a. Quantitative Easing (QE): QE involves the central bank purchasing large amounts of long-term government securities and other assets, such as mortgage-backed securities. The purpose of QE is to lower interest rates over the long term, encourage borrowing and investment, and support asset prices.
b. Forward Guidance: Forward guidance provides explicit guidance about the future path of interest rates or other policy actions to influence market expectations and shape future economic outcomes. The central bank attempts to influence long-term interest rates and inflation expectations by signaling its intentions.
c. Negative interest rates: In some cases, the central bank may adopt negative interest rates, charging banks a fee for holding excess reserves. The purpose of negative interest rates is to encourage banks to lend and businesses and consumers to spend, thereby stimulating economic activity.
d. Credit Easing: Credit easing involves targeted purchases of specific entities, such as corporate bonds or commercial paper, to support credit markets for business and household consumers.
3. Inflation Targetism
Inflation targeting is a monetary policy framework in which the central bank sets a clear target for inflation and adjusts its policy tools to achieve that target. The central bank communicates its inflation targets with the public and uses interest rate reviews, forward guidance, and other measures to achieve price stability.
4. Exchange Rate Targetism
Exchange rate peggedness is the process of pegging one’s domestic currency to a foreign currency or a currency basket. The central bank sells or buys its currency in the foreign exchange market in order to maintain the political balance that can influence the domestic currency.
a. Fixed exchange rate: A fixed exchange rate is created by the governing central bank by selling or buying its currency against a specified foreign currency.
b. Managed float: In a managed float system, the central bank floats the exchange rate within a certain range, but smooths out excessive market volatility or achieves particular policy objectives.
5. Policy Coordination
In some cases, the central bank may coordinate its monetary policies with other central banks or government agencies to achieve common objectives, such as global financial stability or coordinated economic stimulus.
Monetary policy plays an important role in shaping the overall performance of an economy by influencing the money supply, interest rates, inflation, exchange rates and financial market conditions. Central banks use a variety of traditional and unconventional instruments and strategies to achieve their policy objectives and respond to economic conditions and financial market changes and activities. Effective monetary policy requires careful analysis, communication and coordination to support sustainable economic growth, price stability and financial stability.
Looking at the period from 2008 to 2024, we understand the dynamic role of monetary policy, which is important in stabilizing economies during crises and stimulating growth during periods of expansion. Following the 2008 global financial crisis, monetary authorities around the world implemented unusual measures, such as mechanical inflation, to stimulate economic reconstruction. In the following years, policymakers adjusted rates and used inflation guidance, such as to combat role tensions and provide support in trade disputes. Amid the COVID-19 pandemic, a sharp monetary stimulus package was immediately implemented to mitigate the economic fallout and support liquidity. Looking ahead, central banks face the challenge of normalizing policy amid monetary pressures and balancing growth objectives with financial stability concerns. The evolution of monetary policy over the years reflects its important role in helping economies sustain stability through turbulent times and being able to adjust to changing economic scenarios.
