U.S. Treasurys traded near flat on Monday as investors prepared to make room for the rest of the week's $96 billion in longer-dated government debt supply.
The Treasury kicked off the week's supply with the sale of $32 billion in two-year notes at a high yield of 0.323 percent, with the highest bid-to-cover ratio in six months.
"The auction was very well bid,'' said Thomas Simons, a money market economist at Jefferies & Co in New York.
Monday's auction was the smallest monthly supply of this maturity since August 2008.
Benchmark 10-year Treasury notes remained unchanged in price to a yield of 2.516 percent. The 10-year yield touched a three-month low of 2.471 percent last week after disappointing September jobs figures.
The government began reducing the size of its two-year auctions in August as a result of lower borrowing needs and ahead of introducing two-year floating-rate debt in early 2014.
The two-year auction will be followed by a $35 billion sale of five-year notes on Tuesday and a $29 billion auction of seven-year notes on Wednesday.
Traders and analysts anticipated solid demand for this week's sales on views the Federal Reserve will keep buying bonds at its current pace to prop up the economy, which was weakened by this month's 16-day partial government shutdown.
