#美国国债 High interest rates on U.S. government bonds, if not lowered, make it **unlikely that the U.S. economy will collapse in the short term, but it faces significant recession risks** for the following reasons:

1. **Increased fiscal burden:** The government pays higher interest on massive debts, squeezing other expenditures or being forced to increase taxes/bonds, which is unsustainable.

2. **Economic vitality suppressed:** High borrowing costs for businesses and consumers inhibit investment, home purchases, and consumption, dragging down economic growth.

3. **Potential financial risks:** A high interest rate environment may expose vulnerabilities in the financial system (such as risks related to certain banks or corporate debts), triggering localized turmoil.

**Conclusion:** While an immediate collapse is unlikely, maintaining high interest rates for an extended period could very likely drag the U.S. economy into a deep recession and exacerbate fiscal difficulties. The Federal Reserve needs to navigate the difficult balance between combating inflation and supporting growth.
