NEW YORK (CNNMoney.com) -- Bond prices turned higher Monday after a report showed weak May home sales, driving yields lower, while the dollar declined against the euro and yen.
The 10-year Treasury note gained 11/32, or $3.44 on a $1,000 note, to yield 5.08 percent, down from 5.13 Friday.
The 30-year note gained 20/32, or $6.25 on a $1,000 note, to yield 5.20 percent, down from 5.25 percent. Bond prices and yields move in opposite directions.
The five-year note gained 6/32 to yield 4.96 percent, and the two-year moved up two ticks to yield 4.88 percent.
In economic news, home sales slumped to a four-year low in May. Prices fell from a year earlier for the 10th straight month, a real estate group said Monday in a report showing no sign of a housing market rebound.
Existing homes sold at an annual pace of 5.99 million last month, down from a revised 6.01 million rate in April, according to the report from the National Association of Realtors. It was the slowest pace of home sales since June 2003, although it was essentially unchanged from the original April reading.
Economists surveyed by Briefing.com had forecast a 6 million sales pace.
Trading could also be volatile later this week before the Federal Reserve releases its latest decision on interest rates and its policy statement, due Thursday at 2:15 p.m.
In currency trading the euro bought $1.347, up from $1.346 from Friday. The dollar bought ¥123.59, down from ¥123.78.
