U.S. federal government debt now exceeds 120% of national GDP — a level nearly unprecedented in history — with no signs of slowing. According to Maurice Obstfeld, former chief economist of the IMF, "the current political foundation is truly very bad." Possible scenarios that could trigger a crisis are not lacking: an AI bubble bursting and dragging the stock market down, or investors dumping U.S. government bonds as happened briefly on April 3, 2025, when Trump announced broad tariffs. Treasury Secretary Scott Bessent is betting on productivity gains from AI to fill the budget gap — a scenario that independent analysts view as fantasy. Trump shows no concern about the ballooning debt, while Republicans in Congress show no signs of restraining him.
The Fed has no good options left — the only way out is fiscal reform in Congress, but that is virtually impossible to achieve.
Analysis
The last time the world faced a global financial crisis in 2008, Washington was able to convene the G20, coordinate with major central banks, and inject global liquidity within weeks. This time, that mechanism is virtually nonfunctional.
The problem is not just the scale of the debt — 120% of GDP is a worrying figure, but Japan has endured over 200% without collapsing. The real risk lies in a toxic combination of three factors: first, foreign investors no longer buy U.S. bonds out of loyalty but for yield — and they are ready to sell the moment conditions worsen; second, the Federal Reserve (Fed) is under mounting political pressure from Trump, weakening the independence that has been the market's anchor; third, China — the partner that recycles trade surpluses into U.S. assets — has no incentive to address the imbalance when subsidized export policies continue to create domestic jobs.
If a bond sell-off occurs and the Fed is forced to buy in to keep interest rates down, inflation will return — triggering a spiral of dollar depreciation. Obstfeld says bluntly: the Fed has no good options left. This is a liquidity trap version of political geography, and the world lacks both a guide and a map.
Diaspora Impact
Two groups within the Vietnamese American community in the U.S. will be directly affected if the crisis erupts.
First, those sending remittances to Vietnam monthly — an estimated hundreds of thousands of families, concentrated in Southern California, Houston, and San Jose. If the dollar loses value because the Fed is pressured to print money, the purchasing power of each $500 sent back will drop significantly according to exchange rates — and international transfer fees typically rise with currency volatility.
Second, Vietnamese American real estate investors in Southern California and Houston holding mortgages at floating interest rates. If government bond yields rise sharply — as seen in the brief sell-off in April 2025 — mortgage rates will follow suit, squeezing cash flow for those holding rental portfolios or recently refinanced.
