The United States has crossed a fiscal milestone that would have seemed almost unimaginable a decade ago. On 18 August 2026, total US national debt reached US$40.047 trillion, according to the US Treasury. The debt has more than doubled from approximately US$19.95 trillion in January 2017.  The significance of US$40 trillion is not the number itself. The bigger question is whether the American economy and government revenues can grow sufficiently to service the debt without requiring progressively larger borrowing. That is the real fiscal test—and it is a question Malaysia should take seriously. The US experience is therefore not a warning that Malaysia is about to face an American-style debt crisis. It is a warning about how a manageable fiscal problem can become politically and economically difficult to correct if structural deficits are allowed to persist for too long.
