Per Woofun AI, the ongoing geopolitical friction between the United States and Iran has triggered a sharp rise in crude oil prices, subsequently elevating inflation expectations and pushing US Treasury yields to their highest levels since 2007. Current data indicates that the 10-year Treasury yield has climbed to 4.58%, significantly surpassing the 4.13% baseline forecast by the Congressional Budget Office (CBO), while the 30-year bond yield has also breached its multi-year peak.

This yield curve steepening imposes substantial fiscal pressure, with projections suggesting an additional $8 billion in interest expenses if current rates persist through the end of the current fiscal year. Should these elevated levels endure through the entirety of the 2027 fiscal year, the incremental interest burden could exceed $30 billion. Market participants are increasingly wary that persistent inflationary pressures, compounded by widening budget deficits, may accelerate bond sell-offs.

Concurrently, rising long-term rates are driving up mortgage costs, sparking speculation that the Treasury might increase ultra-short-term debt issuance or that the Federal Reserve could revive 'Operation Twist'-style interventions to manage yield volatility.
