Benchmark 10-year Treasury yields moved down nearly 9 basis points to 4.306%, and the 2-year Treasury yield slipped almost seven basis points to 4.094%. One basis point equals 0.01%, and yields and prices move inversely, meaning yields fall when prices rise.

Tuesday’s numbers also come after a series of shaky economic data releases last week. The University of Michigan’s consumer sentiment index dropped more than expected in February, and existing home sales in January declined. The S&P Global Purchasing Managers’ Index for February also fell short of economists’ forecasts, all of which combined to raise concerns over the pace of U.S. economic expansion.
