Barclays suggests a shift in investor composition , with private and mutual funds becoming key buyers , is underpinning the persistent rise in 30-year US Treasury yields amid inflation concerns and geopolitical tensions.
Barclays says a changing mix of investors in the US Treasury market is helping keep 30-year yields at elevated levels, as value-focused mutual funds, households and other private buyers step in where traditional demand has been less accommodating.
The bank’s strategists, Demi Hu and Anshul Pradan, argued in a note that these buyers are likely to insist on increasingly generous returns to own long-dated government debt while inflation remains sticky. That dynamic, they said, has contributed to the climb in yields on the longest maturities to levels not seen for decades.
The backdrop has been a powerful sell-off in long bonds. In May, the yield on the 30-year Treasury rose to 5.20%, its highest point since 2007, as investors responded to firmer inflation readings and higher energy prices. Around the same time, a $25 billion sale of new 30-year notes was awarded at 5.046%, only a touch above pre-sale trading levels, suggesting demand was steady rather than exuberant.
The same pressure has been visible beyond the United States. Bloomberg reported that global long-dated sovereign yields in May climbed to their highest since the aftermath of the financial crisis, reflecting worries that persistent inflation could keep central banks cautious for longer. Rising crude prices, driven in part by tensions in the Middle East, also fed the move higher.
Barclays’ point is that the buyer base itself may now be reinforcing those higher levels. As private investors and mutual funds become more prominent in the market for long bonds, the bank suggests the Treasury market may be less forgiving of weak inflation data or any loss of confidence in the path of policy rates. That leaves 30-year debt vulnerable to staying expensive to buy, even after the recent run-up in yields has already drawn in some contrarian money managers.
Earlier this year, some investors were already treating the approach of 5% on the 30-year note as an attractive entry point, while February brought a separate rally in Treasuries as investors sought safety amid geopolitical strains, stock-market weakness and anxiety about private credit. The latest Barclays view suggests that those swings have not changed the underlying balance: long-dated US government bonds remain highly sensitive to inflation, and buyers appear willing to demand a premium for taking that risk.
