Had you asked me two weeks ago, I would have questioned your sanity. Of course, they were safe. However, now I'm not so sure anymore.
Two reasons:
1.) The U.S. has an enormous amount of debt, but given the strength of the U.S. economy, it was reasonable to believe that the country would continue growing and be able to repay it. Now, it seems the U.S. is heading into a recession—if it isn't already in one—and at this point, nobody knows how severe it might become.
2.) If Trump announced tomorrow that the U.S. would stop paying interest on Treasuries held by China for example, absolutely nobody would be surprised. He could frame it as a negotiating tactic or invent some bogus reason, like [claiming fraud](https://www.reuters.com/markets/us/trump-says-us-might-have-less-debt-than-thought-2025-02-09/). Such a move would align perfectly with his personal character, his history of business dealings with contractors, and his demonstrated indifference to economic fallout. Fox News would likely praise him for it, along with half the country.
So yes, if I held U.S. Treasuries, I would be slightly worried by now. What do you think?
