Record! US Bond Yield Breaks 5%, Highest in 19 Years

Global bond markets have been shaken by another wave of selling. Yields on government debt in several major countries have jumped to their highest levels since the 2008 global financial crisis, or even since 2007.

In the United States, the yield on the 10-year Treasury broke through 5.004%, briefly touching 5.041% on Tuesday (15/9/2026). This is the highest level since the close on 9 July 2007, or in 19 years.

The surge in yields raises financing costs for governments and corporations alike, while increasing pressure on countries with high levels of debt.

The rise in yields comes amid growing concerns about inflation and the direction of central bank policy. The widening conflict in the Middle East has pushed oil prices back above US$100 per barrel.

The jump in energy prices could reignite inflation, pressuring central banks to maintain or even raise interest rates.

Markets expect the Federal Reserve (the Fed) to raise interest rates for the first time since 2023 on Wednesday (16/9/2026). The Bank of Japan (BoJ) is also expected to hike rates on Friday (18/9/2026).

Meanwhile, the European Central Bank (ECB) raised rates last week and remains open to further increases in the coming months.

The rise in yields does not only affect bond investors.

For governments, higher yields mean greater costs to issue new debt. Interest payment burdens also grow, potentially reducing fiscal space to fund social programmes, defence and other government spending.

“A 5% yield is not a problem if the economy grows 6.5%. But if growth is only 5% while yields sit at 5%, it is a different story,” said Samy Chaar, Chief Economist at Lombard Odier, quoted by Reuters.

Treasury Yields Sound a Market Alarm

The rise in the 10-year US Treasury yield above 5% has drawn significant global market attention. The instrument is one of the key benchmarks for pricing a wide range of financial assets, from corporate bonds to loans.

As such, rising Treasury yields can increase funding costs across many countries.

However, the United States’ ability to cope with higher debt costs is considered better than several other countries, given its relatively strong economic growth.

A number of analysts believe the US economy may still grow sufficiently to sustain 10-year borrowing costs above 5%. Other countries, however, may not have the same capacity.

Investors Lose Certainty

Pressure in the bond market has been exacerbated by growing uncertainty over the direction of central bank policy.

Fed Chair Kevin Warsh is known to dislike forward guidance, the practice of giving clear signals about the future direction of monetary policy.

This means investors must rely more heavily on economic data and statements from central bank officials to determine the path of interest rates.

“All central banks are now entering a new era without forward guidance. They are simply trying to build credibility and trust. But as seen in the bond market today, that approach has not yet succeeded,” said Shriya Samarth, Head of EMEA Rates at StoneX, speaking to Reuters.

In her view, the market currently faces multiple problems simultaneously, from the surge in capital spending on artificial intelligence (AI), fiscal concerns, to high levels of government debt.

“AI capital spending adds to the problem. There is anxiety over fiscal policy. US debt has now reached US$40 trillion. Debt-to-GDP ratios in the UK and the eurozone are also at historically high levels,” she said.

Global Yields Soar Too

The rise in yields is not confined to the United States. In Japan, the 10-year government bond yield has broken through 3%, the highest level in three decades.

In Germany, the 10-year yield reached around 3.55%, approaching its highest level since 2009. France’s 10-year government bond yield is also near an 18-year high.

Meanwhile, the UK’s 10-year gilt yield hit 5.45%, its highest level since 2007.

These conditions show that the pressure on bond markets has spread across major economies.

Stock Markets Have Not Fallen, But Risks Are Rising

Interestingly, the rise in bond yields has yet to halt the global stock market rally.

Global equities have actually recorded strong gains this year, particularly in shares linked to the artificial intelligence (AI) boom.

The surge in AI sector investment has driven increased capital expenditure, financing and corporate profit growth.

However, rising yields remain a threat to equity markets, as they can increase the cost of capital and make riskier assets relatively less attractive compared with bonds.

“If yields continue to rise, there will certainly be knock-on effects across various markets,” said Khoon Goh, Head of Asia Research at ANZ.

Amid these conditions, the US government has taken several steps to contain the rise in long-term yields, including increasing purchases of government bonds through buybacks.

However, these measures have so far failed to significantly halt the selling pressure.

James Bilson, Global Fixed Income Strategist at Schroders, believes the current rise in US yields does not signal increased government credit risk.

In his view, the bond market’s main problems lie instead in fiscal policy and inflation.

“The combination of policies in place today is too loose to bring inflation sustainably down to 2%,” he said.

“This is the root cause of the current bond market weakness. If inflation can be brought under control, many other problems will become far easier to resolve.”
