Treasury yields declined after a CNBC report said the Treasury could use the General Account to finance a bond buyback. The 10-year Treasury note yield dropped by over 3 basis points to 4.704%. Meanwhile, the 30-year Treasury bond yield fell more than 4 basis points to 5.234%, pulling back after surpassing 5.3% last week—a level last observed nearly two decades ago.

However, Citadel Securities labeled Scott Bessent’s expanded bond buyback initiative as “financial repression.” In a note to clients accessed by Bloomberg, Nohshad Shah, head of EMEA fixed-income sales at Citadel Securities, described the policy as failing to solve the underlying drivers of surging yields.

Furthermore, to isolate Iran and bring an end to the war, the Treasury chief announced an “economic D-Day” campaign, threatening economic sanctions against any country conducting business with the nation and offering no additional hints regarding adjustments to U.S. debt management strategy. 

Investor attention was solely focused on the semiconductor sector ahead of quarterly earnings from Nvidia (NVDA) and Marvell Technologies (MRVL).
