Bond Markets Hit Hard: Wall Street Says Sell-Off Won't End Soon

The Wall Street Journal reports that global bond markets are undergoing a significant sell-off, pushing up borrowing costs for governments, businesses, and households in developed countries. Wall Street sees no sign that this decline will end soon.

Bond yields have risen to their highest levels in 19 years, with investors attributing the sell-off to multiple factors—from ongoing Middle East tensions fueling inflation worries, to a surge in tech companies issuing bonds to compete for bond fund capital.

Investors are also unsettled by government budget deficits and uncertainty surrounding the policy direction of the new Federal Reserve chair.

There is no consensus on which factor should be weighted more heavily, but most agree on one point: these conditions are unlikely to disappear in the short term.

More importantly, many believe there’s an even larger force behind the bond sell-off: the economy's continued resilience despite interest rates previously thought high enough to severely dampen growth.

Some argue that if the 2008–2009 financial crisis ushered in the era of ultra-low interest rates, today’s market environment may signal a return to pre-crisis conditions.

Investors are reluctant to buy long-term bonds, fearing that interest rates could rise further—or sharply—even if the Fed takes no immediate action.

Robert Tipp, investment strategist and head of global bonds at PGIM Credit, said, 'Essentially, this is a form of normalization.'

In recent days, government bond yields across nations have climbed to multi-year highs. When bond prices fall, yields rise. Notably, the 30-year U.S. Treasury yield has surpassed 5.3%, reaching levels not seen since 2007.

The 10-year U.S. Treasury yield—the most critical benchmark for borrowing costs—is also approaching its highest level since early 2025.

So far, the sell-off has been largely confined to the bond market. Stock markets remain near all-time highs, and corporate earnings remain strong, suggesting that higher interest expenses have yet to constrain economic growth.

However, if yields continue to rise, the impact will extend far beyond Wall Street.

One of the most directly affected parties is the government itself. As old bonds mature and are replaced with new ones, governments will have to pay higher interest on their ever-growing debt.

Even before this year’s sharp rise in yields, interest payments were already consuming an increasing share of the federal budget.

Now, nearly one dollar out of every five dollars in government revenue goes toward interest payments.

Over the past half-century, U.S. federal government interest payments averaged 2.1% of GDP.

According to projections from the Congressional Budget Office (CBO), this ratio will rise to 3.3% this year and climb further to 4.6% by 2036.

But the actual situation could be worse.

The CBO’s earlier forecast assumed a 10-year U.S. Treasury yield of 4.1%, far below the current level of around 4.7%.

If 10-year yields remain elevated, governments may need to incorporate higher borrowing costs into future forecasts.

Currently, publicly held U.S. government debt stands at approximately 100% of GDP, nearing the historical record set after World War II.

This massive debt burden makes the U.S. increasingly sensitive to interest rate changes.

According to CBO data, if all interest rates are 0.1 percentage points higher than expected, net interest spending would increase by $379 billion.

Michael Strain, director of economic policy studies at the conservative American Enterprise Institute, said, 'The problem isn’t entirely about rising interest rates. It’s about deficits. If we had to worry about just one thing, it should be the deficit outlook over the next decade.'

Rising yields also carry political implications.

U.S. Treasuries play a crucial role in determining overall economy-wide borrowing costs, including 30-year mortgage rates.

Trump was elected largely due to voter concerns about affordability and has repeatedly promised to lower mortgage rates.

U.S. Treasury Secretary Scott Bessent, early in Trump’s second term, stated that the government would work to reduce the 10-year Treasury yield, partly by cutting the fiscal deficit to reduce the supply of bonds entering the market.

Yet these efforts have so far yielded no results, and polls show voter dissatisfaction with the economy remains high, weakening Republicans’ chances in midterm elections.

In recent weeks, Bessent has taken steps analysts believe may relate to at least preventing further rises in Treasury yields. These include intervening in foreign exchange markets to support the yen, potentially easing pressure on the Japanese government to sell U.S. Treasuries to prop up the yen.

Still, yields continue to climb, exposing the limits of these measures.

Zach Griffiths, head of investment-grade bonds and strategy at research firm CreditSights, said, 'So far, the Treasury secretary’s actions may not have achieved the effect he hoped for, and that’s another reason we think this yield rise could persist.'

One encouraging development is that U.S. Treasury yields edged slightly lower on Tuesday. According to Tradeweb data, the 10-year Treasury yield fell from Monday’s 4.725% to 4.706%.

Stock markets declined, with the Nasdaq Composite falling 1.3%, the S&P 500 down 0.7%, and the Dow Jones Industrial Average dropping 0.2%.

Chip stocks were hit hard, with all 30 components of the Philadelphia Semiconductor Index falling during trading. The index posted its largest drop since July 1 and is now down about 19% from its record closing high on June 22. Nonetheless, major indices remain up double digits for the year.

Keith Lerner, chief investment officer at Truist Advisory Services, said, 'So far, the market has been able to ignore the impact of rising yields… because we’ve been in an environment of robust corporate earnings growth. But I think as earnings season ends, the market will pay more attention to yields.'
