Public debt
What is public debt?
Public debt refers to money owed by a government to third parties, such as individuals, financial institutions or other governments. Governments resort to the issuance of public debt to finance expenditures when their revenues are not sufficient to cover their needs. This debt is issued in the form of financial instruments such as bonds and treasury bills.
How does public debt work?
Public debt is a mechanism that allows governments to obtain additional financing when their revenues are not sufficient to cover their expenditures. This process involves the issuance of financial instruments, such as bonds and treasury bills, which are bought by investors in the financial markets. Let’s look at the key steps of how it works:
Need for Financing
When a government needs financing to cover budget deficits, investments or projects, it issues public debt. This occurs when its fiscal revenues, such as taxes and other sources of income, are not sufficient to cover its expenditures.
Issuance of Debt Instruments
To raise funds, the government issues debt instruments, such as bonds and treasury bills. These instruments are basically promises of repayment in the future in exchange for financing in the present.
Financial Markets
These debt instruments are made available to investors in the financial markets. Investors may be individuals, financial institutions, investment funds, central banks or other governments.
Auctions and Sales
In many cases, governments issue debt through auctions. At an auction, investors bid to purchase the debt instruments. Bonds and treasury bills are sold to the investors offering the highest price (for bonds) or the highest discount (for treasury bills).
Interest and Coupon Payments
Bonds generate periodic interest payments, known as coupons, which represent a portion of the bond’s interest rate. Investors receive these payments during the life of the bond. Treasury bills, on the other hand, are sold at a discount and do not pay periodic interest; instead, investors receive the face value at maturity.
Repayment of Principal
At the end of the maturity term, both bonds and treasury bills reach maturity. At this point, the government repays the face value of the debt instruments to investors. For bonds, this also includes the last interest payment.
Impact on the Economy
The issuance of government debt can have an impact on the country’s economy. On the one hand, it provides financing for government projects and programs. On the other hand, it can increase the supply of debt in the financial markets, which could influence interest rates and private investment.

Types of public debt
Treasury bills
Treasury bills are debt instruments issued by the government with a relatively short term, usually less than one year. These issues are a way to obtain short-term financing to cover temporary cash needs. Treasury bills are often issued in standardized denominations and sold at auctions. Investors buy these bills at a price slightly below face value and, when they mature, the government repays the full face value. The difference between the purchase price and the face value represents the interest investors earn.
Government bonds
Government bonds are a common form of medium- and long-term debt issued by the government. These bonds have maturities that can range from several years to decades. Unlike treasury bills, government bonds typically generate periodic interest payments, known as coupons. These payments provide investors with a steady stream of income over the life of the bond. At maturity, the government repays the face value of the bond. Government bonds can be attractive to investors seeking long-term, predictable income investments.
Government bonds
Government bonds are similar to government bonds in terms of issuance and maturity. However, they may have unique features depending on the financial needs of the issuing government. These features may include conversion options to equity, flexible maturity dates or variable interest payment structures. Government bonds allow governments to customize their debt issuance to appeal to different types of investors and meet their specific financial objectives.
When is the level of government debt bad or good?
Determining whether the level of public debt is positive or negative requires a thorough analysis of several interrelated factors:
Debt sustainability
An unsustainable level of debt is problematic as it can lead to long-term financial difficulties. If interest and principal payments consume a significant portion of the government budget, this could limit the government’s ability to finance essential services and investment programs.
Debt-to-GDP ratio
The ratio of debt to gross domestic product (GDP) is a key indicator of a country’s ability to manage its debt. A high ratio may indicate that the country is borrowing in excess relative to its economy. However, a moderate ratio can be manageable if the government uses the funds efficiently to stimulate economic growth.
Destination of funds
The quality of government debt also depends on how the funds are used. If used for productive investments, such as infrastructure or education, the debt could boost long-term economic growth. In contrast, if it is used to finance current expenditures, such as government salaries, without generating long-term economic value, it could be considered less favorable.
Economic conditions
In times of recession or crisis, temporarily increasing public debt may be necessary to stimulate the economy and prevent further deterioration. However, responsible debt management involves adjusting debt when economic conditions improve to avoid excessive accumulation.
Ultimately, a balanced approach to public debt management involves considering these factors together and adapting to changing economic circumstances.
