U.S. intermediate- and long-dated Treasury yields hit their lowest in over two weeks on Tuesday after further declines in oil prices underscored mild inflation, while weak U.S. economic data pointed to a more dovish Federal Reserve.

The weakness in oil prices helped push yields on Treasurys maturing within 7 to 30 years to their lowest since March 2. Longer-dated Treasurys benefit from signs of mild inflation, since inflation erodes the value of interest payouts.
