Odaily News Goldman Sachs Group Inc. President John Waldron said bond traders are increasingly concerned about rising U.S. government debt levels, which has now become a bigger risk than tariffs. "While all the focus has been on tariffs, I think the focus is really shifting, especially in the bond market, to the U.S. budget debate and fiscal situation, which I think is a little worrying," said John Waldron, president of Goldman Sachs Group Inc. "I think the biggest risk at the macro level right now is no longer tariffs."
