U.S. Treasurys yields edged up on Wednesday as investors took profits from the recent rally, before Thursday's highly anticipated European Central Bank meeting.
The ECB is expected to cut interest rates and announce other measures to help stimulate growth in the region. Bonds rallied in May, in part in anticipation of the ECB's actions. But yields have risen back from 11-month lows reached on Thursday as investors take profits.
"A lot of the ECB has been priced in and you see some profit taking ahead of them," said Sean Murphy, a Treasurys trader at Societe Generale in New York. The ECB meeting also comes before Friday's U.S. employment report for May, which could mark a volatile two days of trading.
Benchmark 10-year note yields rose above a technical support level of 2.60 percent on Wednesday, and are up from 2.40 percent last week.
Disappointment at the ECB's announcement on Thursday or a stronger than expected jobs figure on Friday could push the notes' year note yields more firmly back into the range of 2.60 percent to 2.80 percent, where they had traded from late January until May.
