Picture This: Sovereign yields have risen to multi-decade highs in major markets

10-year US Treasury yields have risen to their highest level since the early 2000s.

• 10-year sovereign yields in the UK and Japan are at their highest levels since the mid- to late-1990s. 

The increases have recently accelerated.

• The 10-year US Treasury yield rose by over 50 basis points in September.

Various factors are driving up yields, including: 

• Higher short-term interest rate expectations. This partly reflects conflict-related inflation pressures. Expectations of short-term interest rates in the US are also rising due to higher estimates of potential growth and the neutral level of policy rates. 
• Higher term premia*. Factors include high debt ratios and persistent large budget deficits. [*The additional compensation investors require to hold longer maturity bonds instead of rolling over short-term bonds.]
• Increased competition for capital. High volumes of sovereign debt issuance and huge AI-related funding needs. 

Yields in France have risen more than in other major markets amid high political and fiscal risks, with key elections in April 2027. France’s 10-year yield spread to Germany has more than doubled over 2026 to date, to over 130 basis points.  

Economic growth

• High yields raise debt servicing costs, further reducing governments’ fiscal space to support growth and counter adverse shocks. 
• Sovereign yields are a benchmark for private-sector borrowing costs, and rises in both imply weaker economic conditions down the line. 

Market conditions

• Sharply rising yields can lead to adverse “snowball” effects – i.e., a cycle of rising yields and budget deficits - which worsen the trajectory of debt ratios and increase the likelihood of market turmoil. 
• Sustained rises in yields raise the risk of equity market corrections.
