A global sell-off in government bonds has intensified, pushing the benchmark US 10-year Treasury yield above 5.27%, its highest level in 19 years, as investors respond to rising oil prices, persistent inflation and growing public debt.

The 10-year yield reached an intraday high of approximately 5.27% on Monday before closing at 5.241%, its highest closing level since June 2007\. It has climbed by nearly half a percentage point during September, placing the Treasury market on course for its worst monthly performance in two years.

[Bond prices move in the opposite direction to yields](https://www.investopedia.com/articles/bonds/07/price%5Fyield.asp?ref=theglobalvoice.com). When investors sell government debt, prices decline and the yield required to attract buyers rises. Those higher yields then increase borrowing costs across the economy because government bonds provide the benchmark for mortgages, corporate loans and other forms of credit.

The sell-off has spread across different Treasury maturities. The two-year US yield, which is particularly sensitive to expectations about Federal Reserve policy, has risen by more than 0.57 percentage points this month and is approaching 5%. The 30-year yield has climbed to around 5.55%, its highest level since 2004.

The immediate pressure came from a renewed rise in oil prices after hopes faded for an agreement between the United States and Iran that could restore secure movement through the [Strait of Hormuz](https://www.theglobalvoice.com/vessel-struck-by-unknown-projectile-inside-strait-of-hormuz/). Brent crude briefly rose above $108 a barrel before surrendering part of the increase.

Higher energy prices threaten to keep inflation elevated by increasing transportation, manufacturing and household costs. Investors are consequently preparing for the possibility that the Federal Reserve will have to raise interest rates further and keep them elevated for longer.

The Fed increased rates earlier in September, its first rise since 2023, and indicated that another increase could follow before the end of the year. Market pricing now suggests that traders expect as many as three additional increases by the middle of 2027.

Strong US economic data have added to the pressure. Business activity expanded faster than expected in September, reducing expectations of an economic slowdown that might otherwise allow the Fed to relax monetary policy. Weak demand at some recent Treasury auctions has also forced the government to offer higher returns to attract buyers.

The problem extends beyond inflation and central-bank policy. Investors are increasingly concerned about the volume of debt being issued by governments running large fiscal deficits. [The United States has crossed the $40 trillion debt threshold](https://fiscaldata.treasury.gov/americas-finance-guide/national-debt/?ref=theglobalvoice.com), while heavy corporate borrowing, including financing for artificial-intelligence infrastructure, has added more supply to global debt markets.

The effects are visible across other major economies. Britain’s 10-year government-bond yield reached approximately 5.4%, its highest level in nearly two decades. Germany’s equivalent yield rose to around 3.65%, the highest since 2009, while French and Italian borrowing costs also increased.

Asian bond markets have come under similar pressure. Yields have risen in Japan, South Korea and Australia, with Japan’s 10-year government-bond yield recently reaching levels last recorded in 1996.

Stocks have also been affected. The S&P 500 fell 0.8% on Monday, while the Dow Jones Industrial Average declined 0.7% and the Nasdaq lost 0.9%. Higher bond yields make government debt more attractive relative to shares and reduce the present value investors assign to future corporate earnings.

The bond rout is therefore creating pressure far beyond government finances. It threatens to raise mortgage payments, increase corporate refinancing costs and restrict public spending as interest payments consume a larger share of national budgets. For emerging economies, higher US yields can also attract capital towards dollar assets, placing pressure on currencies and domestic financial markets.
