Ray Dalio has spent years warning that America's debt trajectory could eventually collide with the bond market.

Now he is pointing to two of the most important players on the other side of that market.

The Bridgewater Associates founder warned Tuesday that China and Japan could reduce their appetite for U.S. Treasury securities, potentially weakening an important source of demand for American government debt at a time when Treasury yields are already at multi-decade highs. Dalio made the comments in a Bloomberg Television interview in Singapore, arguing that geopolitical tensions make it difficult for China to continue accumulating U.S. debt while Japan is looking to repatriate capital after lending enormous sums abroad.

His warning arrives at an uncomfortable moment.

The U.S. 10-year Treasury yield is hovering around 5.3%, near levels last seen in 2002, after a major global bond selloff pushed long-term borrowing costs sharply higher.

The potential danger is straightforward.

If one of the world's biggest debt issuers needs to borrow enormous sums while two of its biggest foreign creditors become less willing to buy that debt, the market may demand a higher interest rate to absorb the supply.

And higher yields mean higher financing costs for Washington.

Dalio's warning is not based entirely on a hypothetical future.

U.S. Treasury data already show a long-running decline in China's holdings.

At the end of July 2026, mainland China held approximately $618 billion of Treasury securities, down from about $633.4 billion in June and $699.2 billion a year earlier.

The decline is part of a broader trend.

China's Treasury holdings have fallen substantially over the past several years as Beijing has sought greater diversification and reduced reliance on dollar assets.

But Dalio's point is more political than simply financial.

He argued that the traditional debtor-creditor relationship becomes more complicated when the two countries increasingly view each other as strategic adversaries.

A creditor can continue lending to an economic rival.

But the incentives change when that rival is also a geopolitical competitor.

That is why Dalio believes China's demand for Treasuries could weaken further.

Japan is a different story.

It remains the largest foreign holder of U.S. Treasury securities, with approximately $1.104 trillion at the end of July. But that was down from $1.117 trillion in June and marked a third consecutive monthly decline.

The reason Japan matters so much is the size of the number.

Japan's financial institutions and investors have accumulated enormous amounts of overseas assets over decades, partly because Japanese interest rates were exceptionally low for a long period.

That created powerful incentives to invest abroad.

Now the environment is changing.

Japanese yields are rising.

Domestic investment opportunities are becoming more attractive.

And if Japanese investors can earn better returns at home—or if currency considerations make foreign assets less attractive—they have a stronger incentive to bring money back.

Dalio's argument is that Japan has already “lent a lot of money” overseas and could increasingly want that capital back.

It is important not to overstate the risk.

The United States issues debt in its own currency.

Treasuries remain one of the deepest and most liquid markets in the world.

There is no automatic mechanism by which China or Japan selling Treasuries would cause a U.S. funding crisis.

But foreign demand still matters.

The Treasury Department's latest TIC data show that foreign investors collectively hold trillions of dollars of U.S. government securities, and Treasury officials continue to monitor foreign flows as part of the broader financing environment.

When a major source of demand becomes less enthusiastic, the market can adjust through price.

Bond prices fall.

Yields rise.

The government pays more.

The same process can spread into corporate borrowing and consumer credit.

That's why the composition of Treasury demand matters even if the United States retains ample access to capital.

Dalio's comments would be less alarming if Treasury yields were comfortably low.

They are not.

The 10-year yield recently climbed above 5.3%, reaching levels not seen since the early 2000s. The 30-year Treasury yield has also moved to multi-decade highs.

The rise reflects several forces at once.

Inflation remains above the Federal Reserve's target.

Oil prices have risen sharply because of the Middle East conflict.

The U.S. government continues to run large fiscal deficits.

And major technology companies are themselves borrowing heavily to fund AI infrastructure.

Reuters recently reported that Alphabet, Amazon and Microsoft together had issued roughly $220 billion of debt in 2026, more than twice the amount issued the previous year.

That matters because governments and corporations are effectively competing for the same pool of global savings.

The more capital private companies demand, the more expensive government borrowing can become if investors require higher returns across the bond market.

Dalio also repeated his warning that the United States could face a potential debt crisis within roughly three years.

That does not mean he is predicting the U.S. government will suddenly default.

His broader concern is a feedback loop.

Debt rises.

Interest payments increase.

The government borrows more to finance existing obligations.

Investors demand higher yields.

Higher yields make the deficit larger.

The government then needs still more borrowing.

That cycle can eventually become difficult to reverse.

Dalio has previously described such an outcome as a point where debt-financed spending begins constraining the broader economy.

His latest warning focuses on one of the most important variables in that equation: who buys the debt.

Treasury Secretary Scott Bessent has tried to reassure investors that the trajectory of U.S. government borrowing can improve.

Bessent has argued that a combination of economic growth and spending restraint will begin to change the debt trajectory relatively quickly.

That puts the two narratives in direct contrast.

Dalio is emphasizing the danger created by declining foreign demand and high debt.

Bessent is emphasizing growth and fiscal measures that could eventually reduce borrowing pressure.

The market ultimately has to decide which story is more credible.

And unlike an economic forecast, that judgment appears directly in Treasury yields.

Japan's potential repatriation of capital isn't limited to Treasuries.

Japanese investors have historically been major holders of foreign government and corporate bonds.

If Japanese yields rise enough to make domestic assets more attractive, capital can flow home from several markets.

That could affect U.S. Treasuries.

It could also affect European sovereign bonds and other fixed-income markets.

In that sense, Japan's financial decisions can become a global liquidity story.

A relatively small change in the behavior of one of the world's largest pools of savings can affect borrowing costs far beyond Tokyo.

China's relationship with U.S. debt has a different dynamic.

Beijing has enormous foreign-exchange reserves and needs liquid, relatively safe assets.

Treasuries remain difficult to replace at scale.

So China does not necessarily need to dump its existing holdings to reduce dependence on the United States.

It can simply stop increasing them.

That distinction is critical.

A gradual decline in purchases can be just as important as an outright selloff if the U.S. government must continually issue large amounts of new debt.

The market then needs other buyers to absorb the additional supply.

Those buyers may demand higher yields.

There is an unexpected connection between Dalio's warning and the technology boom.

AI infrastructure is creating enormous demand for financing.

Data centers cost billions.

Cloud companies are issuing debt.

Chipmakers are expanding factories.

Power companies are investing in new generation and transmission.

The global economy is therefore entering a period of extraordinarily high capital expenditure at the same time that governments are running large deficits. Reuters has described AI-related borrowing as one factor contributing to the broader global bond selloff.

That doesn't mean AI is causing America's debt problem.

It means the supply and demand for capital are becoming increasingly intertwined.

The government isn't borrowing in isolation.

Corporate America isn't borrowing in isolation either.

Everyone is competing for savings.

There are several possible outcomes.

Other investors can step in.

U.S. households can hold more Treasuries through funds and retirement accounts.

Banks and money-market funds can absorb more government debt.

Foreign investors outside China and Japan can increase their purchases.

And higher yields themselves can attract buyers.

This last mechanism is important.

If Treasury yields rise enough, investors may decide that the additional return is worth the risk.

The market can therefore self-correct.

But the correction occurs through higher borrowing costs.

That's the problem Dalio is emphasizing.

A weaker dollar could eventually accompany a structural reduction in foreign demand.

If overseas investors reduce purchases of dollar assets, demand for the currency can soften.

At the same time, higher Treasury yields can initially support the dollar by making U.S. assets more attractive.

Those forces can move in opposite directions.

The result could be greater currency volatility alongside greater bond volatility.

And the combination matters because many international investors hedge currency exposure when buying U.S. bonds.

Changes in hedging costs can alter the attractiveness of Treasuries even before a foreign institution decides to sell.

The important thing about his latest comments is not that China and Japan are about to abandon U.S. government debt.

There is no evidence of such an immediate, coordinated exit.

Japan remains the world's largest foreign Treasury holder, while China still owns hundreds of billions of dollars of U.S. government securities.

The issue is the direction of travel.

If the biggest foreign creditors become less willing to finance America's borrowing while the Treasury market is already demanding yields above 5%, Washington has less room for error.

The United States may still be able to finance itself.

But financing could become progressively more expensive.

And that would eventually affect the whole economy.

Dalio's debt warning is ultimately a market question rather than a prediction that can be settled by one interview.

If foreign demand stays resilient, Treasury yields could stabilize.

If Japan repatriates more capital and China continues reducing its holdings, the market may demand greater compensation for absorbing America's debt.

If inflation remains high, that pressure could intensify.

And if fiscal deficits remain large, the problem becomes even more difficult.

For investors, the signal to watch is not simply what Ray Dalio says next.

It is what happens to Treasury yields, foreign holdings and the demand at government debt auctions.

Because the bond market speaks in one language that policymakers cannot easily override.

Price.

And right now, the price of borrowing for the United States is getting noticeably higher.
