Global bonds are experiencing a significant sell-off, driving borrowing costs to multi-decade highs. This rout is fueled by several factors, including ongoing conflict in the Middle East pushing energy prices up, investor anxieties about inflation, and expanding government debt. Sovereign yields, which serve as benchmarks for asset prices, are increasing, leading to higher mortgage rates for consumers and challenging budgetary decisions for governments as their funding costs climb. For instance, Brent crude futures recently rose by 1% to $95.61 per barrel, after a nearly 6% gain in the prior session.
The impact is visible across major markets: the yield on 10-year U.S. Treasury notes has reached a near three-year high of 4.81%, with analysts suggesting a further climb towards 5% is likely and could unsettle stock markets. Japan's 10-year yield is above 3%, a 30-year high, while Australia's 10-year government bond yields hit 5.198%, their highest in over 15 years. Similarly, the UK 30-year bond yield reached 5.86%, a level not seen since 1998, and Germany's 10-year Bund is at a 15-year high of 3.35%.
Several reasons contribute to investors demanding a higher premium. Charu Chanana, chief investment strategist at Saxo, points to increasing demands for inflation premiums, fiscal risks, and the sheer volume of new debt entering the market. Macquarie Group also highlights the abundance of bonds—due to significant government borrowing and tech companies funding AI growth—as a key factor. Nick Ferres, CIO of Vantage Point Asset Management, warns that current rates will begin to strain public and private sector debt servicing, with higher yields negatively affecting valuations, especially in long-duration growth sectors. While some analysts believe a 5% yield on US 10-year Treasuries could attract strong demand, including intervention from Treasury Secretary Scott Bessent, the consensus acknowledges the potential for further market unsettling.
