David Frum: “This has been a week of pain for anyone who borrows money.”“All over the world, lenders are demanding higher interest rates. The global bond market is extracting higher yields from every borrower, starting with the biggest borrowers of all: national governments. But not every government is paying equally.”“Trustworthy borrowers with solid finances and honest leadership pay less. Distrusted borrowers with disordered finances and corrupt leaders pay more. In times past, the United States would have headed that first list. Under President Trump, the United States has tumbled onto the second one.”
