KEY POINTS
  • August was one of the most volatile months in recent memory for the U.S. bond market with economists and strategists blaming trade-related slowdown fears.
  • "I don't think you'll get anybody to say that the trade policy has not changed the probability of recession," says Bill Poole, former leader of the Federal Reserve Bank of St. Louis.
  • The 10-year yield last posted a fall of at least 50 basis in a single calendar month in January 2015, making August's move one of the largest in the post-crisis era.

In normal times, the U.S. Treasury market could be described as "stable," "reliable" or even "boring." August, however, was not normal.
