Treasury yields fell precipitously after the auction, with benchmark 10-year Treasury note yields hitting their lowest since December 14 and 30-year bond yields touching their lowest since December 8. An earlier 2.5-percent drop in US pending home sales had set the table for yields to move lower, analysts said. "We started off with pending home sales being kind of squishy, weak ... the effect was to start to cap the selloff in Treasuries," said Aaron Kohli, interest rate strategist at BMO Capital Markets. "It culminated with the buying at the auction, which then drove yields much, much lower."
The strong appetite for 5-year Treasuries at the auction was likely the catalyst for investor short covering, Kohli said, with 5-year notes having taken the brunt of the selloff in Treasuries that has unraveled since the election of Donald Trump as US president. "The market is being a bit too optimistic in terms of what can actually happen next year, and as a result has pushed up Treasury yields too much," Kohli said.
When investors sell Treasuries it lowers prices, which move inversely to yields. The 10-year note was last up 14/32 in price to yield 2.51 percent. The 30-year yield was up 30/32 in price to yield 3.09 percent. Prior to the selloff, worries in Europe about rescue plans for shaky Italian banks had driven the gap between benchmark US 10-year notes and their German counterparts to the widest level on record.
The selloff in Treasuries tightened the yield spread, which had risen as investors bought safe-haven German Bunds in the first trading day there since the Christmas break. That pushed the gap between US and German 10-year paper to a record wide 237 basis points as German 10-year yields fell to their lowest since November 9.
