NEW YORK (MarketWatch) -- Treasurys declined Monday, pushing yields up, before the government sells $25 billion in three-year notes, the first sale of the security since May 2007. Two-year note yields rose 5 basis points to 1.38%. The auction is the first of three this week, putting upward pressure on yields. Bids are due at 11:30 a.m. Eastern, earlier than usual because bond trading is expected to be suspended early today and remain on hold Tuesday in observance of Veterans Day. Treasurys are also weaker after the government restructured its plan to bail out American International Group and China announced a $585 billion package to stimulate its economy.
