The US Treasury will auction 10-year debt later in the day providing a focus for price action in the absence of major economic data. A sale of three-year debt was well received on Monday. "This is going to be the best barometer for what kind of demand there is at these level and I think it goes well," said Craig Collins, trader at Bank of Montreal in London. Demand for US debt remains high as the euro zone struggles to overcome its debt problems, leaving investors keen to buy low-risk, liquid assets in order to secure the return of their investment. "Any kinds of dips are going to be an opportunity to buy and those who are looking for a concession to take us closer to 2 percent are, I think, going to be left out in the cold," Collins said. Ten-year Treasury yields were half a basis point higher on the day at 1.97 percent, with two-year yields unchanged at 0.2445 percent. Treasury futures were last at 130-24/32, up 1/32, with traders pointing to equity markets as the main driver behind moves within the day's range. European equities were slightly lower and US stock futures pointed to a marginally lower open on Wall Street. Technical charts also offered support for Treasury futures around current levels. Societe Generale said a short-term support line, based on a weekly chart showing a rising trend since late October, offered support at 130-11/32. "At the lowest, 129-26/32 should contain any downward attempt until the 10-year T-Note returns to the December high of 131-13/32 - 131-14/32 and then to the September high of 131-28/32," Societe Generale's technical analysts said.
