The US 30-year Treasury yield has remained above the 5% threshold for the longest continuous period since the onset of the global financial crisis in 2007.
This sustained elevation marks a significant shift in the long-end of the curve, reflecting deepening investor anxiety over the trajectory of US public debt and the persistence of inflationary pressures.
The repricing of long-dated bonds is driven by a confluence of structural factors.
Investors are increasingly concerned about the deteriorating US fiscal picture, exacerbated by a surge in government issuance required to fund massive infrastructure projects, particularly in the artificial intelligence sector.
The sheer volume of new supply is testing market absorption capacity, pushing yields higher as buyers demand greater compensation for duration risk.
This development challenges the long-held perception of Treasuries as a purely 'risk-free' asset.
