TREASURY WRAP: T-NOTE FUTURES (U6) SETTLE 6 TICKS HIGHER AT 108-14+

T-notes bull flatten on buyback sources. At settlement, 2-year -0.6bps at 4.234%, 3-year -1.3bps at 4.300%, 5-year -2.5bps at 4.403%, 7-year -3.3bps at 4.535%, 10-year -4.0bps at 4.696%, 20-year -5.1bps at 5.214%, 30-year -4.9bps at 5.227%. THE DAY: Treasury yields fell across the curve on Monday, with the long end outperforming and resulting in a bull flattening of the curve. The front end was relatively anchored in comparison, while yields declined by as much as 5bps further out the curve. Focus remains firmly on the long end following last week's Treasury buyback announcement. The latest source reports suggested that the Treasury could use funds from the Treasury General Account, which currently stands around USD 1tln, to finance additional buybacks. Meanwhile, FBN cited Wall Street executives familiar with Bessent's thinking as saying he will do whatever it takes to "put the fear of God" into bond vigilantes who short the long end in an attempt to drive the 10-year yield towards 5%. The report suggested potential measures could include further buybacks, greater short-term issuance and even changes to long-dated issuance, including the possible elimination of the 20-year bond. Bessent also confirmed an escalation of the administration's campaign against Iran, announcing Operation Economic Outcast, including secondary sanctions targeting key Iranian sectors such as shipping, aviation, gold, technology and digital assets. Bessent subsequently warned against conducting business with Iran, particularly those turning a blind eye to seaborne and overland oil transfers designed to circumvent sanctions. Aside from fundamentals, there was also a chunky Treasury futures curve block worth highlighting.
