What Are the Consequences of China Selling U.S. Treasuries? Analyzing the Economic Chain Reaction Behind $771 Billion

The size of U.S. Treasury bonds will surpass $35 trillion in 2024, accounting for over 120% of the country’s GDP. As the second-largest foreign holder of U.S. debt, China once held $771 billion in U.S. Treasuries. What would happen to the global economy if China suddenly sold all its U.S. bonds? This seemingly simple financial decision actually hides complex chain reactions across the world economy.

Why China is the second-largest foreign holder as U.S. debt exceeds $35 trillion

America’s debt problem stems from its long-term deficit spending. Whether it’s infrastructure, social welfare, or military expenses, the U.S. government spends far more than it collects in taxes. Facing a shortage of financial resources, the U.S. turns to global markets for funding, attracting governments, investment institutions, and corporations worldwide as creditors.

The U.S. continues to attract investors to buy Treasuries mainly because of its established international credit system. The dollar’s status as the global reserve currency, combined with the large size of the U.S. economy and a relatively mature financial system, makes U.S. debt widely regarded as a relatively safe investment. As the world’s largest trading exporter, China has accumulated vast dollar reserves, a significant portion of which is invested in U.S. Treasuries as a key part of its foreign exchange asset allocation.

However, as the scale of U.S. debt keeps growing, this sense of security is being challenged. The debt-to-GDP ratio has exceeded 120%, raising increasing doubts about the U.S. government’s ability to repay.

What would happen to the U.S. economy if China sells all its U.S. debt?

Although China’s holdings of $771 billion in Treasuries account for only about 2% of the total $35 trillion U.S. debt, in the international financial markets, this 2% represents a massive amount of capital capable of shaking the market.

Direct impact: rising borrowing costs

If China announces to sell all its U.S. Treasuries, the supply of Treasuries in the market would suddenly surge. According to basic supply and demand principles, increased supply leads to falling prices. A decline in Treasury prices means yields rise—investors will demand higher returns to buy discounted bonds. This directly raises the borrowing costs for the U.S. government. For the federal government, it means paying more in interest each year, further straining its fiscal budget.

Secondary impact: social and economic pressure

As borrowing costs increase, the U.S. government would face a dilemma: raise taxes or cut spending to cover the growing deficit. Tax hikes would directly hit middle-class purchasing power, with higher payroll, consumption, and other taxes leading to weaker consumer spending. Spending cuts could mean reductions in social programs like healthcare, food assistance, and housing subsidies, harming low-income families. Meanwhile, higher financing costs for businesses would suppress investment and employment, potentially increasing unemployment.

Risk of economic recession

Market turbulence in the Treasuries sector would spill over into stocks, real estate, and other asset markets. Investor confidence could plummet, causing significant stock market corrections and affecting housing markets due to higher financing costs. With growth slowing, the U.S. could enter a recession.

Domino effects on global financial markets

U.S. Treasuries are not only a financial tool for America but also a cornerstone of the global financial system. Banks, pension funds, insurance companies worldwide hold Treasuries as a core asset.

Exchange rate volatility and capital flight

A sell-off of Treasuries could trigger a credit crisis that quickly spreads to currency markets. The dollar’s status as a reserve currency could weaken, facing depreciation pressure. Simultaneously, global investors might panic and accelerate capital outflows from U.S. assets to other markets. Emerging markets would face capital flight, their currencies would depreciate, import prices would rise, and inflation could accelerate—repeating scenarios seen in Latin America, Southeast Asia, Argentina, Turkey, and others over past decades.

Market chain reactions

Global stock markets, commodities, and cryptocurrencies would experience volatility. Safe-haven assets like gold and Swiss francs would attract capital, further intensifying market divergence. International trade could become chaotic, protectionism might rise, and global economic growth could slow down.

Risks for China in selling U.S. Treasuries

A seemingly decisive move—selling all U.S. debt—would come with significant costs for China itself.

The double-edged sword of dollar depreciation

China is the world’s largest foreign exchange reserve holder, with a significant portion in U.S. dollar assets. Selling large amounts of Treasuries would likely cause the dollar to depreciate, reducing the value of China’s dollar holdings. Converting $771 billion into RMB would significantly diminish its purchasing power, meaning decades of accumulated reserves could suffer substantial losses.

Damage to international credibility

Massive selling of U.S. Treasuries could be interpreted as a rejection of U.S. creditworthiness, potentially triggering a chain reaction. Other creditor countries might follow suit, leading China to become a catalyst for a global financial crisis, risking international isolation and criticism. Additionally, China’s future government or corporate financing abroad could be adversely affected by a loss of credibility.

Why China prefers holding rather than selling: strategic considerations in economic diplomacy

Given the complex interests involved, China opts to hold U.S. Treasuries long-term rather than sell them all at once. This decision reflects deep strategic thinking.

Holding the cards, wielding negotiation leverage

Owning large amounts of U.S. debt is a display of economic strength. In international trade negotiations, these assets can serve as bargaining chips. China doesn’t need to sell immediately; merely maintaining the possibility of selling can influence U.S. policies. This approach is more cost-effective than actual liquidation, providing leverage without causing short-term damage.

Risk diversification and gradual reduction

In recent years, China has adopted a more rational strategy—gradually and orderly reducing its U.S. debt holdings while increasing investments in other countries’ bonds. This approach helps lower dollar exposure step-by-step without triggering market chaos.

De-dollarization movement: the ultimate alternative to selling Treasuries

Compared to outright selling Treasuries, the most impactful move against U.S. economic dominance is the global push for de-dollarization.

The cost of dollar hegemony

Over the past decades, the U.S. has repeatedly exploited dollar dominance for economic gains. When the U.S. economy cools, the Federal Reserve launches money printing and quantitative easing, injecting liquidity into markets. These dollars flow worldwide, especially into financially fragile emerging markets, which accumulate large dollar-denominated debt. When the U.S. economy recovers, the Fed raises interest rates, attracting capital back to the U.S. and causing crises in developing countries—such as Latin America’s “Lost Decade,” the 1997 Asian financial crisis, and recent crises in Argentina and Turkey.

Global de-dollarization efforts

By 2024, nearly half of all countries have begun de-dollarization initiatives. BRICS nations have developed independent financial clearing systems to bypass traditional dollar settlement channels. China actively promotes the internationalization of the RMB, with more international trade priced and settled in yuan. Europe is exploring establishing a payment system independent of the dollar.

This de-dollarization movement is more powerful than simply selling Treasuries. It fundamentally undermines the dollar’s role as the world’s reserve currency and reshapes the global financial landscape.

Looking ahead: opportunities and challenges for emerging economies

In this reconfiguration of the global financial order, China, as the largest emerging economy, plays a pivotal role. Every move—whether holding or selling Treasuries, promoting the internationalization of the yuan, or establishing new financial mechanisms—could influence the future of the global economy.

In the short term, the expansion of U.S. debt and the strain on U.S. creditworthiness will persist. But in the long run, the dollar-centered international financial system is undergoing profound adjustments. De-dollarization will not happen overnight; it requires collective efforts to build a new international financial order. During this transition, rationality, cooperation, and cautious decision-making are essential for all countries.

China’s holdings of U.S. debt should neither be weaponized for retaliation nor passively exposed to dollar depreciation risks. Within the framework of economic diplomacy, orderly and rational asset reallocation is the best strategy to navigate the complex international landscape.
