Why can't countries just print their own money instead of going into debt?

This question sounds contradictory: if every country has the right to print its own money, why do they need to borrow from other nations? The answer lies deep within the foundations of the modern international monetary system and how the world organizes trade activities among nations.

Imagine the world after World War II as a large village, where each country is like a family specializing in production. The Russian family makes tools, the American family produces consumer goods, the Chinese family sews clothing, the German family manufactures parts, the French family produces perfume, and the Vietnamese family grows rice. To live well, each family must buy goods from others—that is, import activities.

Problems arise when everyone needs a common means of payment. Gold could be ideal, but it’s too heavy and hard to divide. In 1944, after WWII, the Bretton Woods system was established, setting the US dollar as the international currency, backed by a promise to convert to gold. The American—strong, wealthy, and trustworthy—declared: “From now on, you can use my money for transactions. This money is called the US dollar, and it’s linked to gold.”

Since then, all international transactions have used the US dollar as the standard.

The US dollar: International currency and foreign exchange power

Why do countries have to borrow dollars instead of printing their own money? The reason is simple but profound: when other countries want to sell goods to the US or to each other, they won’t accept their own printed currencies but only the US dollar. That’s because the dollar is backed by the strongest household in the “village”—the US—and everyone trusts it.

There are other currencies like the Euro or the Renminbi, but they are only accepted within certain limits. Only the US dollar is considered a “global reserve currency,” widely used worldwide to store value and conduct international trade.

If Vietnam has $100 billion in US dollars from exports but needs to buy machinery from Germany, Vietnam must pay in dollars. Without dollars, Vietnam would have to borrow or buy on credit, converting to US dollars. No country can print US dollars itself—only the US Federal Reserve has that authority.

Every country can print money, but not the US dollar

Every country truly has the right to print its own money through its central bank. However, when importing foreign goods, these countries face a fundamental problem: international suppliers don’t trust the currencies of smaller nations.

Consider a real scenario: Country A prints 1 million banknotes, but only 100,000 households need to use them. If A keeps printing more, each note will lose value. Domestic prices will rise, but the money in people’s hands will lose purchasing power. The result: inflation.

This basic principle applies to all currencies: their value is determined by supply and demand. When supply exceeds demand, money depreciates; when demand exceeds supply, money appreciates. A country must find a balance point; otherwise, it risks economic consequences similar to Zimbabwe’s hyperinflation.

Zimbabwe’s reckless money printing: A lesson in inflation

Why can’t every country just print money without borrowing? The answer is illustrated by a recent historical example: Zimbabwe under Mugabe.

In 1980, upon independence, Zimbabwe was one of Africa’s wealthiest countries. Its economy was diverse, industrialized, and productive. The exchange rate was 1 USD = 0.678 Zimbabwe dollars. People from other countries wanted to settle there because of prosperity.

But in the late 1990s, when war veterans demanded post-war benefits, Mugabe—who held a master’s degree in law and administration from the UK—decided to print more money. He believed economic problems could be solved by simply printing currency.

Initially, after veterans received money for infrastructure projects, they started shopping—buying clothes, then cars. With supply not keeping up, prices doubled. Sellers realized the money was losing value and raised prices to compensate. A vicious cycle began.

Mugabe kept printing money, hoping people would have enough to buy goods. But the opposite happened: hyperinflation exploded.

• 1997: 1 USD = 10 Zimbabwe dollars
• 2002: 1 USD = 1,000 Zimbabwe dollars
• 2006: 1 USD = 500,000 Zimbabwe dollars
• 2008: inflation reached 220,000%
• 2009: inflation was beyond calculation

Zimbabweans had to carry wheelbarrows of cash to buy a loaf of bread. The fourth generation of Zimbabwean currency was eventually exchanged for 1 trillion Zimbabwe dollars of the third generation.

The clear lesson from Zimbabwe: every country can print money, but it must do so responsibly. Printing more money than the economy’s real output and services leads to severe inflation.

Foreign exchange reserves: Indicators of economic health

To survive in the global economy, countries need to accumulate foreign currencies—especially US dollars. The amount of foreign currency reserves a country holds is called “foreign exchange reserves in USD.” It’s a crucial indicator, like savings in a family’s bank account.

Countries earn foreign currency through:

• Exporting goods and services: selling abroad and earning dollars
• Remittances: workers abroad sending money home
• Foreign investments: foreign investors putting money into the country

When China faced the 1997 Hong Kong financial crisis, its massive foreign reserves saved the situation. Currently, the countries with the largest foreign reserves include:

• China: $3.5 trillion
• Japan: $1.4 trillion
• Switzerland: $1 trillion

Why only the US can print “recklessly”?

It may seem unfair, but the truth is: only the US has the ability to print money beyond normal limits without catastrophic consequences.

Why? Because the US dollar is used worldwide, so the effects of excessive issuance are shared globally, not just borne by the US.

The US employs three steps to issue money:

1. Printing: The Federal Reserve prints high-denomination bills
2. Spending: The US government spends on defense, infrastructure, etc. US companies receive this money and buy goods globally, paying foreigners in dollars
3. Circulation: Foreign entities receive dollars and continue spending them to buy goods, creating a flow of dollars

This mechanism is called “quantitative easing.” Through it, the US can print more money than most other countries without causing excessive inflation, because the inflationary costs are shared worldwide.

However, even the US cannot print unlimited money. Excessive printing would devalue the dollar rapidly, causing global inflation—harmful to the US itself. Therefore, the US must control its money supply within acceptable limits.

The vicious cycle of international debt

Although the US has the power to print money for global use, it is paradoxically the most indebted country. This is a major contradiction in the global economy.

Other countries borrow because they need foreign currency to import. Without dollars, they can’t buy essential goods. Each country must consider: print its own money or borrow US dollars? Excessive printing leads to inflation like Zimbabwe’s; borrowing results in foreign debt.

That’s why nations are “trapped” in the need for foreign reserves. They must export, accumulate dollars, and use them for imports. Without this, reckless money printing leads to Zimbabwe-style hyperinflation.

In summary, every country can print money, but only in proportion to their real economic output. The modern world has chosen the US dollar as the international currency, so other nations must borrow or earn dollars through exports. This isn’t unfair; it’s the outcome of a global economic system that everyone accepts to maintain stability.
