JPMorgan Asset Management said US Treasuries may have bottomed out now amid signs of strong foreign demand and expectations that the Federal Reserve will support US government debt if necessary. "I feel good that we put in low prices and high yields here," said Bob Mitchell, the firm's global head of fixed income, in a statement. "In our conversations with overseas investors, they have not been scared off by Treasuries." The move comes after Treasuries suffered their biggest decline since 2001 as Trump's tariffs and unpredictable policymaking dented demand for long-term safe-haven assets. Mr. Mitchell cited data from the Federal Reserve showing that foreign central banks and reserve managers have recently increased their holdings of Treasuries. He also pointed to recent comments by Fed Collins that the Fed is "absolutely ready" to help stabilize financial marekts if things get messy.
