Government bond markets across the developed world are under renewed pressure, as rising energy costs revive inflation fears and prompt investors to bet that major central banks will keep interest rates elevated for longer than previously anticipated.
The benchmark 10-year US Treasury yield briefly touched 5.011% on Monday, according to Dow Jones Market Data, before slipping back below the symbolic threshold. That marked the highest level since October 2023, reflecting a combination of heavy government borrowing, resilient economic growth, and a wave of corporate debt issuance tied to artificial intelligence investment. Yields move inversely to bond prices, so the surge indicates a sharp drop in demand for government paper.
The move has global implications. In Europe, France's 10-year government bond yield climbed to 4.50% on Monday, while Italy's equivalent reached around 4.40%. Germany's benchmark Bund yield rose as high as 3.538%, its loftiest in 15 years, according to Dow Jones Market Data. These levels echo the eurozone debt crisis era, though the drivers today are different: energy shocks, fiscal expansion, and a repricing of central bank policy.
Energy and inflation: the twin pressures
Energy prices are a major source of the current strain. Brent crude traded around $107 a barrel on Tuesday morning, with US West Texas Intermediate near $103, as attacks on Saudi energy infrastructure and shipping in the Gulf intensified concerns about supplies through the Strait of Hormuz. The spike in oil prices is feeding directly into inflation expectations, complicating the task of central banks trying to bring price growth back to target.
The European Central Bank raised its deposit rate by 25 basis points to 2.5% last week and warned that inflation could remain above its objective for an extended period. Markets are now pricing in at least one further ECB increase this year, a shift that has pushed yields higher across the eurozone. The US Treasury's recent buyback operation also fell short of expectations, adding to the upward pressure on yields.
Rising yields have consequences beyond government borrowing costs. They feed through to mortgages, corporate loans, and other credit instruments, potentially slowing economic growth. They also make bonds more attractive relative to equities, which remain highly valued after a long bull run.
Central bank decisions in focus
Attention now turns to three major central bank meetings this week. The US Federal Reserve announces its decision on Wednesday, followed by the Bank of England on Thursday and the Bank of Japan on Friday. A Reuters poll found that 85% of economists expect the Fed to raise rates by 25 basis points, while money markets put the probability of an increase at around 93%.
The Bank of England is widely expected to hold rates steady, with economists surveyed by Reuters unanimously forecasting no change. However, some analysts caution that a surprise hike cannot be ruled out, given persistent inflation and a tight labour market. The Bank of Japan, meanwhile, is expected to raise borrowing costs, a move that could have ripple effects on global bond markets.
For European investors, the divergence in central bank paths adds another layer of complexity. While the ECB has signalled caution, the Fed's aggressive stance and the BoJ's potential tightening could keep global yields elevated, putting further pressure on European sovereign debt. The trade tensions between the US and Canada are also a reminder of how interconnected global markets have become.
The sell-off is not confined to government bonds. Corporate debt markets are feeling the pinch as well, with borrowing costs rising for companies across sectors. The AI investment boom, which has driven a surge in debt issuance, is now facing a more challenging funding environment as yields climb.
For now, the path of least resistance for yields appears to be higher, unless energy prices retreat or central banks signal a more dovish stance. The coming days will be crucial in determining whether the 5% level on the US 10-year becomes a new norm or a temporary spike.
