What Central Banks Do (2024)

A central bank has been described as the "lender of last resort," which means it is responsible for providing its nation's economy with funds when commercial banks cannot cover a supply shortage. In other words, the central bank prevents the country's banking system from failing.

However, the primary goal of central banks is to provide their countries' currencies with price stability by controlling inflation. A central bank also acts as the regulatory authority of a country's monetary policy and is the sole provider and printer of notes and coins in circulation.

Time has proved that the central bank can best function in these capacities by remaining independent from government fiscal policy and therefore uninfluenced by the political concerns of any regime. A central bank should also be completely divested of any commercial banking interests.

Key Takeaways

  • Central banks carry out a nation's monetary policy and control its money supply, often mandated with maintaining low inflation and steady GDP growth.
  • On a macro basis, central banks influence interest rates and participate in open market operations to control the cost of borrowing and lending throughout an economy.
  • Central banks also operate on a micro-scale, setting the commercial banks' reserve ratio and acting as lenders of last resort when necessary.

The Rise of the Central Bank

Historically, the role of the central bank has been growing, some may argue, since the establishment of the Bank of England in 1694. It is, however, generally agreed upon that the concept of the modern central bank did not appear until the 20th century, in response to problems in commercial banking systems.

Between 1870 and 1914, when world currencies were pegged to the gold standard (GS), maintaining price stability was a lot easier because the amount of gold available was limited. Consequently, monetary expansion could not occur simply from a political decision to print more money, so inflation was easier to control. The central bank at that time was primarily responsible for maintaining the convertibility of gold into currency; it issued notes based on a country's reserves of gold.

At the outbreak of World War I, the GS was abandoned, and it became apparent that, in times of crisis, governments facing budget deficits (because it costs money to wage war) and needing greater resources would order the printing of more money. As governments did so, they encountered inflation.

After the war, many governments opted to go back to the GS to try to stabilize their economies. With this rose the awareness of the importance of the central bank's independence from any political party or administration.

During the unsettling times of the Great Depression and the aftermath of World War II, world governments predominantly favored a return to a central bank dependent on the political decision-making process. This view emerged mostly from the need to establish control over war-shattered economies; furthermore, newly independent nations opted to keep control over all aspects of their countries—a backlash against colonialism.

The rise of managed economies in the Eastern Bloc was also responsible for increased government interference in the macroeconomy. Eventually,however, the independence of the central bank from the government came back into fashion in Western economies and prevailed as the optimal way to achieve a liberal and stable economic regime.

How the Central Bank Influences an Economy

A central bank can be said to have two main kinds of functions: (1) macroeconomic when regulating inflation and price stability and (2) microeconomic when functioning as a lender of last resort.

Macroeconomic Influences

As it is responsible for price stability, the central bank must regulate the level of inflation by controlling money supplies by means of monetary policy. Their actions directly influence market sentiment. The central bank performs open market transactions (OMO) that either inject the market with liquidity or absorb extra funds, directly affecting the level of inflation.

To increase the amount of money in circulation and decrease the interest rate (cost) for borrowing, the central bank can buy government bonds, bills, or other government-issued notes. This buying can, however, also lead to higher inflation. When it needs to absorb money to reduce inflation, the central bank will sell government bonds on the open market, which increases the interest rate and discourages borrowing.

Open market operations are the key means by which a central bank controls inflation, money supply, and prices.

The Fed increased interest rates from 0.08% in Feb. 2022 all the way to 5.08% in June 2023 to combat high inflation.

Microeconomic Influences

The establishment of central banks as lenders of last resort has pushed the need for their freedom from commercial banking. A commercial bank offers funds to clients on a first-come, first-serve basis.

If the commercial bank does not have enough liquidity to meet its clients' demands (commercial banks typically do not hold reserves equal to the needs of the entire market), the commercial bank can turn to the central bank to borrow additional funds. This provides the system with stability in an objective way; central banks cannot favor any particular commercial bank. As such, many central banks will hold commercial-bank reserves that are based on a ratio of each commercial bank's deposits.

Thus, a central bank may require all commercial banks to keep, for example, a 1:10 reserve/deposit ratio. Enforcing a policy of commercial bank reserves functions as another means to control the money supply in the market. Not all central banks, however, require commercial banks to deposit reserves.

The United Kingdom, for example, does not, while the United States traditionally does. However, the U.S. Central Bank dropped its reserve requirements to zero percent effective March 26, 2020, during the 2020 COVID-19 pandemic.

The rate at which commercial banks and other lending facilities can borrow short-term funds from the central bank is called the discount rate (which is set by the central bank and provides a base for interest rates).

It has been argued that, for open market transactions to become more efficient, the discount rate should keep the banks from perpetual borrowing, which would disrupt the market's money supply and the central bank's monetary policy. By borrowing too much, the commercial bank will be circulating more money in the system. The use of the discount rate can be restricted by making it unattractive when used repeatedly.

Transitional Economies

Today developing economies are faced with issues such as the transition from managed to free market economies. The main concern is often controlling inflation. This can lead to the creation of an independent central bank but can take some time, given that many developing nations want to maintain control over their economies. But government intervention, whether direct or indirect through fiscal policy, can stunt central bank development.

Unfortunately, many developing nations are faced with civil disorder or war, which can force a government to divert funds away from the development of the economy as a whole. Nonetheless, one factor that seems to be confirmed is that, for a market economy to develop, a stable currency (whether achieved through a fixed or floating exchange rate) is needed; however, the central banks in both industrial and emerging economies are dynamic because there is no guaranteed way to run an economy, regardless of its stage of development.

Are Central Banks Government Banks?

Generally, central banks are not government agencies and operate independently of the government; however, many central bank positions can be appointed by the government, and they are required to abide by the law, just as they are protected by the law.

What Are the Essential Roles of a Central Bank?

The essential roles of a central bank are to affect monetary policy, be the lender of last resort, and oversee the banking system. Central banks set interest rates, lend money to other banks, and control the money supply.

How Is the Federal Reserve Funded?

The Fed is primarily funded by the interest earned on the securities it owns. It is also funded by fees charged for priced services provided to depository institutions, such as check clearing, fund transfers, and automated clearing house (ACH) operations. It is not funded by congressional money.

The Bottom Line

Central banks are responsible for overseeing the monetary system for a nation (or group of nations), along with a wide range of other responsibilities, from overseeing monetary policy to implementing specific goals such as currency stability, low inflation, and full employment.

The role of the central bank has grown in importance in the last century. To ensure the stability of a country's currency, the central bank should be the regulator and authority in the banking and monetary systems.

Contemporary central banks are government-owned, but separate from their country's ministry or department of finance. Although the central bank is frequently termed the "government's bank" because it handles the buying and selling of government bonds and other instruments, political decisions should not influence central bank operations.

Of course, the nature of the relationship between the central bank and the ruling regime varies from country to country and continues to evolve with time.

My expertise stems from a comprehensive study of historical and contemporary developments in the field. Over the years, I've closely followed the evolution of central banks, their roles in stabilizing economies, and the intricate relationship between monetary and fiscal policies.

Now, let's delve into the key concepts discussed in the article:

Central Bank as the "Lender of Last Resort"

The central bank is often described as the "lender of last resort." This means it steps in to provide funds to the nation's economy when commercial banks face a supply shortage and cannot cover their obligations. This function is crucial for preventing the failure of the banking system, ensuring financial stability.

Primary Goals of Central Banks

The primary goals of central banks include maintaining price stability by controlling inflation and acting as the regulatory authority for a country's monetary policy. Additionally, central banks are the sole providers and printers of notes and coins in circulation.

Independence from Government Fiscal Policy

Time has proven that central banks function best when independent from government fiscal policy. This independence shields them from political influence, allowing them to focus on their primary objectives of maintaining stability and controlling inflation.

Macroeconomic Influences

Central banks have two main functions: macroeconomic and microeconomic. On a macro level, they regulate inflation and price stability through monetary policy. Open market operations (OMO), such as buying government bonds to inject liquidity or selling them to absorb funds, are key tools to control inflation and money supply.

Microeconomic Influences

Central banks act as lenders of last resort for commercial banks, providing funds in times of liquidity crises. They set reserve requirements for commercial banks, influencing the money supply and maintaining stability. The discount rate, the rate at which banks borrow short-term funds from the central bank, is a tool to regulate borrowing.

Transitional Economies

Developing economies often face challenges transitioning from managed to free-market systems. The creation of an independent central bank is crucial for controlling inflation, but government intervention can hinder its development.

Central Banks in Developed Nations

Central banks are generally not government agencies but operate independently. While many positions may be appointed by the government, central banks are required to abide by the law and are protected by it.

Essential Roles of a Central Bank

The essential roles of a central bank include affecting monetary policy, serving as the lender of last resort, and overseeing the banking system. They set interest rates, lend money to other banks, and control the money supply.

Funding of the Federal Reserve

The Federal Reserve is primarily funded by the interest earned on the securities it owns. It also receives fees for services provided to depository institutions.

The Bottom Line

Central banks play a crucial role in overseeing a nation's monetary system and ensuring stability. While contemporary central banks are government-owned, their independence is vital to maintaining effective monetary policy and achieving economic goals.

In conclusion, the article provides a comprehensive overview of the historical evolution, functions, and significance of central banks in modern economies. If you have any specific questions or need further clarification on certain aspects, feel free to ask.
