A surge in oil prices following a reported Iranian attack on energy facilities in the United-Arab-Emirates pushed the 30-year U.S. Treasury yield above 5% on Monday, as renewed inflation fears triggered a broad sell-off in government bonds.
"The bond market is reacting to worries about inflation and the duration of this conflict," said Andrew Szczurowski, a portfolio manager at Morgan Stanley Investment Management. The sharp move in yields reflects a significant repricing of Federal Reserve policy expectations, with interest rate swaps now showing an approximately 80% probability of a Fed rate hike by April 2027, a stark reversal from the rate cut expectations that dominated just months ago.
The sell-off saw yields rise across the curve, with the policy-sensitive two-year note's yield climbing 11 basis points to 3.99%. The 30-year yield rose 6.1 basis points to 5.025%, its highest level since May 2025. The last time the 30-year yield sustained a break above 5% was during the height of the Fed's tightening cycle in 2025. West Texas Intermediate crude oil prices climbed back above $105 a barrel, exacerbating concerns that persistent energy costs will keep inflation elevated and force the Fed to maintain a hawkish stance.
The renewed pressure on bonds comes just two days before the Treasury's quarterly refunding announcement (QRA), which is now expected to reveal increased borrowing needs. On Monday, the Treasury Department unexpectedly raised its net borrowing estimate for the April-to-June quarter to $189 billion, an $80 billion increase from its February projection, citing "lower-than-expected net cash flows." This larger appetite for borrowing adds another layer of pressure on a bond market already strained by geopolitical tensions and persistent inflation. All eyes will be on the Treasury's forward guidance this Wednesday, with investors watching for any change to its statement that it will maintain current auction sizes for "at least the next several quarters."
