30-Year U.S. Bond Yield Reaches Highest Level Since 2004

U.S. long-term borrowing costs reached their highest levels in over 20 years on Thursday, triggering continued widespread selling as investors demand greater compensation for holding government bonds amid strong economic growth, high debt levels, and rising energy costs fueling inflation fears.

Bond markets have faced pressure for months, pushing yields to levels not seen in decades, with energy prices rising due to the war in Iran and growing investor concern over government spending. Bond yields rise as bond prices fall.

Investor anxiety has recently intensified with the accelerating pace of selling in the United States, the world’s largest and most important government bond market. The yield on U.S. Treasury bonds with a 30-year maturity rose to just above 5.45 percent, the highest level since 2004, while the benchmark yield on 10-year U.S. bonds currently stands at 5.158 percent.

Investors have so far absorbed rising yields thanks to robust underlying economic growth, strong corporate profits, and massive AI-driven spending. The Nasdaq index, dominated by the technology sector, closed at a record high last Tuesday.

However, borrowing costs may be approaching a point where global financial markets begin facing disruptions and consumers feel the strain. U.S. 30-year mortgage rates are now one percentage point higher than before the war, at seven percent, near their highest levels in two years.

Chris Skiklona, head of economic research at Daywa Capital, stated, "It's clear that the higher prices go, the worse the situation becomes, and the more expensive U.S. mortgages become, the greater the burden of interest payments on the federal government."

The pace of selling accelerated on Wednesday and Thursday after business activity data indicated strong growth in the United States and increasing inflation pressures, fueling expectations of further rate hikes by the Federal Reserve.

While short-term Treasury yields reflect expectations about interest rates, the yield on 30-year bonds reflects investors’ willingness to finance government borrowing over the coming years.

The world’s largest economies are facing challenges with rising interest payments amid growing spending demands. Germany’s financing agency said today it expects federal borrowing to reach a record 525.5 billion euros (598 billion dollars) in 2026, with further increases expected next year, largely driven by rising refinancing needs and increased requirements for special funds.

The yield on Germany’s benchmark 10-year bund briefly surpassed the 3.5 percent threshold this month, the highest level in 17 years.

On Thursday, the yield on 10-year Japanese government bonds reached its highest level since 1996.

Investors remain optimistic as nominal growth in the United States continues at around eight percent in the second quarter without any signs of a noticeable slowdown. Nominal growth refers to the increase in the monetary value of a country’s total output or income at current market prices, without excluding the impact of inflation.
