Treasuries traders are wrapping up a tumultuous week in which a gauge of bond-market volatility soared to a new high for the year, suggesting more upheaval to come.
In a furious five days of trading, yields first jumped, sending the 10-year yield above 4.2% for the first time since July, before easing as the week wore on. The moves came despite few new catalysts, as investors continued to reassess their outlook for interest-rate cuts from the Federal Reserve and for the US election.
