Treasury prices extended their rise during trading on Thursday as investors rotated out of risk assets into the perceived safety of U.S. government paper. The 10-year Treasury note yield fell 9.2 basis points to 3.135%, while the 2-year note yield was down 4.1 basis points to 2.840%. The 30-year bond yield slipped 9 basis points to 3.311%, according to Tradeweb data. Bond prices move in the opposite direction of yields. U.S. Treasurys have served as a port of call during market turmoil, though that relationship was challenged earlier this week when both prices for bonds and stocks fell together.
