What Is Monetary Economics?

When people hear the term monetary economics, they often have no idea what it really means or why it’s important. It’s a term that comes up in almost every discussion on economics, but few people truly understand its meaning or function in our world today. Monetary economics is all about the concept of money and its impact on the economy around the globe, from large nations to small communities, which makes it one of the most important financial topics out there today. To understand monetary economics better, here are some questions you might want to ask yourself

What Is Monetary Economics?

Money supply

The money supply is the total amount of money available in an economy at a given time. The money supply includes all the coins, paper bills and bank deposits that are currently in circulation. The money supply can be divided into three major components: currency, reserves and deposits. Currency is the physical cash (in other words, coins and paper bills). Reserves are bank balances that have been deposited with a central bank. They often act as collateral or security for loans taken out by banks in order to expand their lending capacity. Deposits are funds placed in accounts at banks or other institutions (such as post offices) that pay interest on the deposits or offer additional benefits such as free checking or free debit cards.

Money demand

Monetary economics is the study of how money and credit affect prices, employment, production and economic growth. The supply of money in an economy is often controlled by a central bank like the Federal Reserve. Money demand refers to how people decide to hold cash balances or other assets instead of spending them on goods and services. When the demand for money rises, the increase will cause interest rates to rise too because it takes more money to purchase a given amount of goods and services. A rise in interest rates decreases investment and consumption, which can lead to lower economic growth. 

If money demand falls (for example, if individuals lose confidence in banks), then both short-term and long-term interest rates may fall as well. Such a reduction would stimulate investment and consumption—leading to higher economic growth.

Equilibrium in the money market

Monetary economics is the study of how money and its characteristics (such as supply, demand, purchasing power, and inflation) affect the economy. This field of study addresses questions such as: What are the effects of changes in the quantity of money on prices? How much does a decrease in income cause a decrease in aggregate demand for goods and services? And what factors determine interest rates and exchange rates? 

The equilibrium theory explains how to best establish an equilibrium in the money market by using three key points: The relationship between supply and demand for money; The determination of interest rates; And balance of payments. The equilibrium in the money market occurs when there is no more need or desire for any change in either supply or demand for cash balances. An equilibrium happens when prices reflect all available information about the monetary system. Prices will rise if there is an increase in the amount of money circulating within an economy because it reduces their scarcity value, causing those holding onto cash to lose out on spending power.

The role of central banks

Today, the majority of countries in the world have a central bank and monetary system. However, these institutions are relatively new; they were first adopted during the 18th century and their purpose was to manage inflation and currency crises caused by printing too much money. Central banks do this by managing a country’s interest rates and setting targets for economic growth. The role of central banks has evolved significantly over time. For instance, in recent years, many central banks became more involved with efforts to stabilize financial markets during periods of turmoil. The European Central Bank (ECB) started issuing bonds that would buy up the debt issued by troubled euro zone governments like Greece, Spain and Italy as a way to boost confidence in the European Union’s economic integration. These policies often go against the mandate of some central banks which typically aim for low inflation rather than stimulating demand during an economic downturn. Other interventions that have come about as a result of volatile global markets include: 

This list is not exhaustive because the role of central banks changes constantly in response to changing global conditions and events.

Monetary policy

Monetary economics is the study of how money affects the economy. Monetary policy is a government’s policies for regulating currency, such as interest rates and taxes. Understanding monetary policy can help you predict economic trends, like inflation or recession, and plan for the future. For example, if you’re saving up to buy a house, knowing the monetary policy will help determine whether it makes more sense to save in an FDIC-insured bank account or invest in stocks that may fluctuate with riskier assets. The Federal Reserve Board meets eight times per year to discuss monetary policy and make adjustments accordingly.


If inflation was too high, then this could cause a recession or even depression. If inflation was too low, then this could lead to unemployment and a slower economy as well as lower profits for companies. Conversely, if inflation was too high, then this could cause a recession or even depression. If inflation is at the right level of 2%, then it should stimulate growth without causing any major problems in the economy. The first thing that monetary economists do when creating a forecast for inflation is look at the output gap. The output gap measures how far below potential output an economy is running. A negative output gap means that there are unemployed workers who would be able to produce more goods if they were put back on the job while a positive one means there are unemployed workers who would need more jobs created so they can work again. Economists also look at how tight money supply is by measuring M2; this measure includes all types of liquid assets including cash, deposits and other forms of money like banknotes, coins, money-market accounts, savings accounts and certificates of deposit). Tightness in M2 will result in higher prices while loosening will result in lower prices.


In a deflationary economy, the prices for goods and services are falling. This can lead to a decrease in inflation, which is the general rise in prices. Deflation is often thought of as negative because it means people are spending less money. However, because of this, there will be less demand for goods and services, which may lead to greater competition among companies and lower prices on certain products. The International Monetary Fund (IMF) has argued that deflation can have an overall positive impact on an economy if it’s caused by good economic policy or low interest rates rather than a severe lack of consumer demand.

Economic growth

Monetary economics is the study of how money and prices affect economic growth. Economic growth, in turn, affects monetary economics. For example, a country with a low inflation rate will likely have higher economic growth than one with high inflation. Economic policies are often designed to affect a country’s money supply in order to spur or slow down economic growth. For example, many central banks lower interest rates to encourage economic growth by making it easier for companies and consumers to borrow money.


-Fiscal policy is about choosing which markets to influence. When faced with tough economic times, an expansionary fiscal policy will allow for more consumption and investment. On the other hand, when faced with strong economic times, a contractionary fiscal policy can lower inflation. The goal of monetary policy is to set rates of interest so that the business sector has enough incentives to invest while being wary of runaway inflation.

-In conclusion, while they do share many similarities, the two differ in how they work and how it impacts the economy.
