US 30-year Treasury yield reaches its highest level since 2004

The yield on the 30-year US Treasury bond climbed above 5.45% on Thursday, reaching its highest level since 2004 as a broad sell-off in government debt intensified. The move reflects growing investor concerns about inflation, higher energy costs, strong economic activity and the increasing cost of government borrowing.

The benchmark 10-year Treasury yield also remained above 5%, reaching around 5.158% during the session. The rise in long-term yields came as economic data pointed to continued resilience in the US economy while investors reassessed the possibility that interest rates could remain elevated for longer than previously expected.

Bond prices and yields move in opposite directions, meaning that the latest increase in yields reflects a significant decline in the market value of existing government debt. Investors are demanding greater returns to hold longer-term securities as they weigh inflation risks, government borrowing requirements and uncertainty over future monetary policy.

Higher Treasury yields are also feeding into borrowing costs for households and businesses. US 30-year mortgage rates recently moved above 7%, reaching their highest level in more than two years and increasing the cost of financing a home for American borrowers.

The pressure is not limited to the United States. Government bond yields have risen across major economies as investors reassess inflation and fiscal risks. Germany's 10-year Bund yield has moved above 3.5%, reaching its highest level in roughly 17 years, while Japan's 10-year government bond yield has climbed to its highest level since 1996.

Rising yields are particularly significant for governments because they increase the cost of refinancing existing debt and issuing new securities. Germany's finance agency expects federal borrowing to reach a record €525.5 billion, or about $598 billion, in 2026, illustrating the scale of financing needs facing major economies.

In the United States, Treasury officials have taken measures aimed at managing borrowing costs, including expanding buybacks of longer-dated debt. However, the measures have so far failed to prevent yields from reaching multi-decade highs as investors continue to demand higher compensation for holding long-term government securities.

Federal Reserve Bank of New York President John Williams said the US economy continues to show notable resilience. At the same time, the latest bond-market moves highlight the growing sensitivity of financial markets to inflation, energy prices and government debt levels.

For financial markets, the sustained rise in long-term yields represents a significant shift in the cost of money. If elevated borrowing costs persist, governments could face larger interest payments while households and companies may encounter more expensive mortgages, loans and other forms of credit.

The latest bond sell-off therefore extends beyond the Treasury market, with potential implications for housing, investment and global financial conditions. The 30-year yield's rise to its highest level since 2004 underscores how inflation expectations, economic resilience and public debt are increasingly shaping the outlook for borrowing costs worldwide.
