US Government Debt & Fiscal Deficit

Concepts

Why Does the Government Borrow Money?

Governments, like individuals, need to borrow when they spend more than they earn. The U.S. government's revenue comes primarily from taxes, but its expenditures — defense, social welfare, healthcare, infrastructure, and more — regularly exceed income. This gap is called the "fiscal deficit," and the government fills it by issuing Treasury bonds.

This is not necessarily a bad thing. Moderate borrowing to invest in infrastructure, education, or R&D can promote long-term economic growth. But if debt keeps snowballing and interest payments consume an ever-larger share of the budget, it is like running up credit card debt — eventually, problems will arise.

Key Indicators to Watch

Total U.S. National Debt (GFDEBTN): This is the cumulative total of federal government debt. It has surpassed $34 trillion in recent years. While the number itself is staggering, the absolute figure alone does not tell the full story because the economy is also growing.

Debt-to-GDP Ratio (GFDEGDQ188S): This is the key metric for assessing whether debt is becoming unmanageable. Just as you would evaluate an individual's debt burden relative to their income rather than the dollar amount alone, this ratio puts debt in context. The U.S. debt-to-GDP ratio currently exceeds 120%, meaning the government owes more than the entire country produces in a year. A similar level was reached after World War II, and it took decades to bring it back down.

Federal Budget Surplus/Deficit: The annual result of government revenue minus expenditures. A deficit means the government spent more than it earned that year and needs to borrow more. The U.S. briefly achieved a budget surplus under the Clinton administration but has run deficits nearly every year since — especially large ones during the financial crisis and the pandemic.

What Is the Debt Ceiling?

The United States has a unique mechanism called the "Debt Ceiling" — a congressionally set cap on total government borrowing. When debt approaches this limit, the Treasury cannot issue new debt. Congress must then vote to raise the ceiling; otherwise, the government may be unable to pay its bills, potentially resulting in a "technical default."

Every debt ceiling negotiation becomes a political showdown, with both parties using it as leverage. Markets get nervous each time. Although the U.S. has never actually defaulted, the 2011 debt ceiling crisis led to the first-ever downgrade of America's credit rating, and stocks experienced significant turbulence.

Impact on Investors

Government debt issues affect investors on several levels. First, increased government borrowing competes with businesses and individuals for capital, potentially pushing interest rates higher. Second, the more of the budget consumed by interest payments, the less the government can spend elsewhere, which may drag on economic growth. Third, if markets begin to question America's ability to service its debt (though the probability remains very low), the credit foundation of the U.S. dollar and Treasuries could be shaken — with repercussions throughout the global financial system.

Hands-On: Using CTSstock

On the CTSstock homepage (/home), navigate to the "Economic Indicators" section, select "United States," and then click into the "Fiscal & Government" category. There you will find historical trend charts for Total National Debt (GFDEBTN), Debt-to-GDP Ratio (GFDEGDQ188S), and the Federal Budget Surplus/Deficit.

Suggested approach:

1. Track the Debt-to-GDP ratio over the long term: If this ratio continues rising with no signs of slowing, watch for potential pressure on interest rates and the economy.
2. Monitor deficit changes: A sudden widening of the deficit usually accompanies a recession or major policy spending. Cross-reference with other economic indicators to assess where the economy stands.
3. Pay attention to debt ceiling events: When debt ceiling headlines appear in the news, check CTSstock for historical context to avoid letting short-term panic cloud your judgment.

FAQ

Q: The U.S. owes this much money — could it go bankrupt? A: Under current conditions, the probability is extremely low. U.S. Treasury bonds are denominated in dollars, and the U.S. has the ability to create dollars (through the Fed), so in theory it can always "pay its bills." However, excessive money printing leads to inflation and dollar depreciation. The real risk of the debt problem is not bankruptcy — it is inflation and erosion of the currency's credibility.

Q: What happens if the debt ceiling is not raised? A: If Congress fails to raise the debt ceiling in time, the Treasury first resorts to "extraordinary measures" to buy time — typically enough to last a few months. If those run out, the government may be unable to pay federal employee salaries, social security benefits, or even interest on its bonds on time, constituting a "technical default." This would trigger severe financial market turmoil. Historically, however, the ceiling has always been raised in the end.

Q: Should investors in Taiwan worry about U.S. national debt? A: Not in the short term, but it is worth monitoring over the long run. U.S. Treasuries are the cornerstone of the global financial system. If cracks appear in that foundation, the impact extends far beyond the U.S. — global stock markets, exchange rates, and interest rates would all be affected. Regularly tracking the trend is far more useful than panicking.
