At present, there is a delicate balancing relationship in world trade between the American dollar and American Treasury bonds. America has reached its highest debt of 40 trillion, which is 126 percent of its GDP. American Treasury bonds work in a systematic, centuries-old, established loop.
The process of the global dollar loop happens outside the borders of America. Countries like China, Germany, Singapore, and other export-oriented countries, countries that remain in a trade surplus, meaning countries whose exports are greater than their imports, accumulate dollar reserves. Now, these same countries faced a problem: what should they do with these dollar reserves? Leaving them uninvested meant suffering losses due to inflation. Meanwhile, converting them completely into local currency would artificially increase the value of their exchange rate, which would harm the competitiveness of their exports.
So, the solution for these dollar reserves was to reinvest them back into America's market. They do this by purchasing Treasury bills, notes, and bonds issued by the US Department of the Treasury. By investing in the Treasury, foreign investors fulfil two main purposes: they earn a safe and fixed interest on their accumulated capital, and they acquire the most easily cash-convertible and reliable assets in global finance. This is how the loop runs and has been running: trade surplus creates reserves, those reserves are reinvested back into the American Treasury, and America benefits from this, using these funds to finance its domestic expenses and ongoing deficit.
However, up to this point, things seem to be going completely right: money is going to the right place, and resources are being utilised well. But as we said in the beginning, America has reached a debt of 40 trillion. Even with 40 trillion of debt, it keeps taking on more. How will the government pay it back? This is the bitter truth of this loop. It has been 25 years since 2001, and the budget has never come into surplus, yet the loop keeps running. How? Because of trust. When the maturity date of bonds and bills arrives, that is, the time to repay the loan, America takes a new loan to repay the old one.
Global demand for American assets has always remained strong, so America has never defaulted on the debt sold in its market, thus maintaining its credibility as the safest risk-free borrower.
America's debt is increasing so rapidly that it is getting trapped in a web where it has to take on more and more debt to repay its old debt. We can see this from the fact that in the past 10 years, American debt has doubled, and this cycle cannot go on forever. If it continues this way, a time will come when America's debt becomes so massive that even after issuing new bills, the loan cannot be fulfilled, or if all investors demand their money back all at once, America will enter a huge economic crisis. To avoid this, America might print a massive amount of new dollars, which would increase inflation, damage the dollar's status and reputation, and lead to America's downfall. Therefore, the long-term survival of this system depends on how a balance is maintained between government spending and government revenue.
The danger of unlimited government debt is not limited to a single country defaulting; rather, it represents a massive mathematical imbalance. When a country begins to accumulate debt at a pace exceeding the rate of global wealth growth, the entire economic system stalls. In such a scenario, only three options remain to save the system: restarting the monetary system from scratch, triggering rampant inflation, or enforcing drastic cuts in government spending.
