The economy is fueled by credit, which refers to borrowed money that requires repayment in the future. It plays a crucial role in driving economic activity. When there is an increase in credit, it leads to greater spending. This increased spending, in turn, generates more income. As a result, lenders are willing to offer a higher amount of credit.

However, it's important to note that credit also generates debt. The borrowed money must be repaid, which means that spending must eventually be reduced in the future. To regulate the economy, central banks have the authority to manipulate interest rates. By adjusting these rates, they can influence the borrowing and lending behaviors of individuals and institutions, thus maintaining a balance in the economy.


Understanding the economy is essential as it has a profound impact on our daily lives. Although the definition of "the economy" may vary, it generally refers to a domain where goods are produced, consumed, and exchanged. Often, discussions revolve around national economies, such as the U.S. economy or the Chinese economy. However, it is also valuable to examine economic activities from a global perspective, considering the interactions and affairs of all countries. In this article, we will explore the fundamental concepts that constitute an economy, drawing insights from Ray Dalio's model.

Who Shapes the Economy?

In our daily lives, we actively participate in economic activities by engaging in both buying (such as groceries) and selling (such as working for payment). Similarly, individuals, groups, governments, and businesses worldwide contribute to the economy through these transactions, which are organized into three market sectors.

The primary sector focuses on the extraction of natural resources, involving activities like logging, mining valuable metals like gold, and various forms of farming. The materials obtained from this sector then move into the secondary sector, which is responsible for manufacturing and production. Lastly, the tertiary sector encompasses a wide range of services, including advertising and distribution.

The widely accepted model of the economy follows this three-sector breakdown. However, some experts have expanded upon it by introducing a quaternary sector and a quinary sector. These additional sectors further distinguish between various services within the tertiary sector.

Before we proceed, let's review these sectors again:

  • Primary sector: extraction of natural resources, including logging, mining valuable metals like gold, and various forms of farming
  • Secondary sector: responsible for manufacturing and production
  • Tertiary sector: encompasses a wide range of services, including advertising and distribution
  • Quaternary sector (optional): further distinguishes various services within the tertiary sector
  • Quinary sector (optional): further distinguishes various services within the tertiary sector

Economic Activity

Gross Domestic Product (GDP) is the most widely used measure to gauge the health of an economy. It calculates the total value of goods and services produced within a country during a specific period. An increasing GDP generally indicates growth in production, income, and spending, while a declining GDP suggests a decrease in these aspects. It's important to note that there are variations of GDP, such as real GDP, which takes inflation into account, and nominal GDP, which does not.

Although GDP is not a perfect measure, it holds significant importance in analyzing the economic well-being of nations, both at domestic and international levels. It is utilized by various entities, ranging from individual market participants to global institutions like the International Monetary Fund, as a tool to gain insights into the economic conditions of different countries.

While GDP provides valuable information, it is advisable to complement its analysis with other data sources to achieve a more comprehensive understanding of the economy, much like the approach taken in technical analysis.

Credit Systems and Interest Rates

Moneylenders and Borrowers

In addition to buying and selling, lending and borrowing play crucial roles in the economy. Suppose you have a significant amount of idle cash that you want to put to work and generate more money. One way to achieve this is by lending money to someone in need, such as a business owner who wants to purchase machinery. They don't currently have the funds, but they can repay you from the sales of their finished products. In this scenario, you act as the lender, while the other party becomes the borrower.

To make the lending arrangement worthwhile, you set a fee known as interest. For example, if you lend $50,000 and specify an interest rate of 2% per month until the loan is repaid, the borrower would owe you $1,000 every month. If the loan is repaid after six months, you would expect to receive $56,000, including the interest specified.

This lending process creates credit, which is an agreement that the borrower will repay the lender at a later time. The concept of credit is familiar to credit card users, where the payment is not immediately deducted from the bank account, and the funds do not need to be available at the time of the transaction, as long as the bill is settled later. However, credit also entails the existence of debt. As a lender, you are owed money, and as a borrower, you owe money. The debt is resolved once the loan is repaid along with the agreed-upon interest.

Banks and Interest Rates

Banks serve as important lenders in our modern society. They act as intermediaries between people who deposit their money and those who need to borrow funds. When individuals deposit money into a bank, they trust that it will be returned to them. With these deposits, banks can provide loans to borrowers.

Banks operate using a fractional reserve system, which means they don't hold onto all the deposited funds. While this approach carries the risk of potential problems if many people simultaneously request their money back, such situations are rare. Instances of widespread loss of confidence in a bank, known as bank runs, can be severe and may result in the bank's collapse. Historical examples include the bank runs during the U.S. Great Depression in 1929 and 1933.

To encourage deposits, banks offer interest rates as incentives. Higher interest rates attract depositors who can earn more money on their deposits. Conversely, borrowers prefer lower interest rates as it reduces the additional amount they need to repay on top of the borrowed sum.

Why Is Credit so Important?

Credit plays a vital role in the economy by enabling individuals, businesses, and governments to spend money they don't currently possess. While some economists view this as problematic, many see increased spending as a sign of a thriving economy. As more money is spent, more people receive income, leading banks to be more willing to lend to individuals with higher incomes. This increased access to cash and credit allows individuals to spend even more, creating a cycle of income generation and spending.

However, this cycle cannot continue indefinitely. When borrowing a significant amount, such as $100,000, it means sacrificing future income to repay the debt. While borrowing allows for temporarily increased spending, eventually, individuals must decrease their spending to settle their debts. Economist Ray Dalio refers to this as the short-term debt cycle, which he suggests occurs in repeating patterns over 5-8 year periods.

Considering the relationship between credit and productivity, it is important to note that productivity continues to rise steadily. Without credit, productivity would be the sole source of growth, as income is typically tied to production. The first part of Dalio's chart illustrates how credit leads to income growth surpassing productivity, resulting in economic expansion. However, this expansion eventually halts, leading to economic contraction. In the second part of the chart, the availability of credit diminishes due to the initial economic boom. Consequently, obtaining loans becomes more challenging, and inflation sets in, prompting government intervention to address the situation.

Inflation, Deflation, and Central Banks


When people have easy access to credit, they can buy more things than they could without it. However, this can lead to a problem where spending increases rapidly while production doesn't keep up. As a result, the demand for goods and services becomes higher than what is available. This causes prices to go up, which is known as inflation. To measure inflation, economists use something called the Consumer Price Index (CPI), which tracks how prices change for everyday things that people buy. The CPI helps us understand how prices are affected by changes in supply and demand.


Deflation occurs when prices decrease over time. It happens because people are spending less money. This can lead to a recession, like what happened in the 2008 Financial Crisis. To try and fix deflation, one idea is to lower interest rates. This makes it cheaper for people to borrow money, so they might spend more. Like inflation, deflation can be measured through a Consumer Price Index.

Central Banks

Central banks play a crucial role in managing a country's monetary policy. Unlike commercial banks that serve individuals and businesses, central banks are government entities responsible for functions such as controlling interest rates and adding to the money supply through measures like quantitative easing. Well-known central banks include the Federal Reserve in the United States, the Bank of England, the Bank of Japan, and the People's Bank of China.

One of the tools central banks have at their disposal is adjusting interest rates. When inflation becomes a concern, central banks may choose to increase interest rates. This makes borrowing more expensive, which can discourage individuals and businesses from taking on new loans and reduce overall spending. The goal is to curb inflation by decreasing demand and, ideally, bringing prices back down. However, it's important to note that higher interest rates can also lead to deflation, which can present its own set of challenges in certain circumstances.

The Economic Bubble Burst

In the world of economics, there are cycles of debt that occur over different timeframes. These cycles involve fluctuations in the availability of credit and levels of debt. Over time, debt can become unsustainable, leading to a period of deleveraging where individuals try to reduce their debt burden. During this phase, incomes decline, credit becomes scarce, and asset prices drop.

To address the challenges of a deleveraging period, governments and central banks employ various strategies. These include reducing spending, forgiving debt, and using expansionary monetary policies like printing money. However, these measures can also have consequences. Reduced spending can result in lower profitability for businesses, job cuts, and higher unemployment rates. Additionally, printing money carries the risk of inflation, which, if not managed properly, can lead to hyperinflation and economic instability.

These cycles of debt and their impacts can be seen throughout history. It is essential for policymakers to carefully navigate these cycles and find a balance between managing debt, stimulating the economy, and maintaining stability.

Dalio's model emphasizes the significance of credit availability in the economy. The expansion and contraction of credit drive the short-term debt cycles, which contribute to the long-term debt cycles. The behavior of participants in the economy is greatly influenced by interest rates. Higher interest rates encourage saving, while lower interest rates promote increased spending.


The economic machine is complex, but if we observe closely, we can identify recurring patterns in the interactions between participants. We have explored the dynamics between lenders and borrowers, the significance of credit and debt, and the measures implemented by central banks to manage economic risks. By gaining insight into these aspects, we can develop a clearer understanding of how the economy functions and the actions taken to prevent potential crises.
