The US Treasury said it has encountered a technical problem affecting its upcoming auctions of 13-week and 26-week Treasury bills, instruments that are typically sold every Monday to help finance government operations. The agency did not specify the nature of the glitch or indicate whether the sales would be delayed or rescheduled. Market participants are monitoring the situation closely because any postponement could temporarily disrupt the government’s short-term funding plans and the cash-management strategies of money-market funds and other investors that rely on regular bill supply. The Treasury has not yet provided a timetable for resolving the issue or announced contingency measures.
