Trump pledged to give every American $5,000 if Republicans win the midterm elections, adding fresh uncertainty to bond markets ahead of a 30-year Treasury auction. The remarks renewed concerns over fiscal discipline and policy unpredictability as Treasury yields traded in a narrow range after the pledge. Trump provided no details, and the proposal is expected to be unlikely to become law. The comments came as 30-year Treasury yields hovered near their highest levels since the global financial crisis, with investors focused on Thursday’s $22 billion auction of bonds maturing in 2056 and CPI data due later this week.
