Summary Box: Interest rates extend gain ahead of Treasury auction of three-year notes

Summary Box: Rates edge higher ahead of auction

THE WAITING GAME: Interest rates rose in the bond market Monday as investors prepared for the Treasury Department’s auction on Tuesday of $40 million in three-year notes.

MAKING ROOM: Prices fell, pushing yields higher. Bond prices often fall before auctions add more supply to the market.

A SLOWER CLIMB: Rates had jumped Friday after the government’s employment report wasn’t as bad as feared. The rise in rates Monday was more modest.
