(Recasts, adds 10-year note auction results, analyst comments) By Karen Brettell and Karen Pierog April 12 (Reuters) - Smooth note auctions on Monday kept a move higher in U.S. Treasury yields in check as the market looked ahead to this week"s 30-year bond offering and key data releases, including consumer price inflation. An auction of $38 billion of 10-year notes resulted in a high yield of 1.680% and a bid-to-cover ratio, a gauge of demand, of 2.36 times. Earlier on Monday, $58 billion of three-year notes were sold at a high yield of 0.376% and with a bid-to-cover ratio of 2.32 times.. "Having two in a day on a Monday and just having them go so far pretty darn well, you couldn"t ask for more," said Jim Vogel, senior rates strategist at FHN Financial in Memphis, Tennessee. The benchmark 10-year yield was last up 1 basis point at 1.6764%, holding below a 14-month high of 1.776% reached on March 30. The three-year yield was last 2.2 basis points higher at 0.3576%. Vogel said yields barely budged following the auctions. "It shows that we"ve got fairly stable yields not because no one"s paying attention, but because for the most part we"re comfortable at least until we get some big new developments," he said. Combined with a $24 billion auction of 30-year bonds on Tuesday, $120 billion in coupon supply hits the market this week, testing investor appetite for debt. Yields have dipped from one-year highs reached last month on improving demand for the debt, though they remain elevated with investors concerned that faster economic growth and rising price pressures will continue to push yields higher. Increasing supply as the government finances higher fiscal spending and widening deficits is adding to the yield increases. Aside from the auctions, the market is also focused on key data this week, including U.S. consumer price data for March due out on Tuesday. Investors are betting that price pressures will increase due to increased fiscal and monetary stimulus and as businesses reopen from COVID-19 related closures. "We"ve built so much in terms of inflation expectations into the market right now that you almost have to have a high CPI report maybe for the next three or four months or people are going to have to maybe reassess how much concern that they"ve already built in about inflation," Vogel said. Comparisons with last year are also likely to be strong, due to a drop in inflation a year ago when businesses closed due to COVID-19. “This is the first month we’re going to see the big base effect pump up the year-over-year comparisons,” said Tom Simons, a money market economist at Jefferies in New York. Market participants are aware of the effect, however, and the Federal Reserve has indicated it will look through any temporary inflation, making it unlikely that a strong number will create a hawkish response from the U.S. central bank. “I don’t think there is a real risk that the hiking timeline is pulled forward or anything like that,” Simons said. Data on Friday showed that U.S. producer prices notched their largest annual gain in 9-1/2 years last month. The two-year Treasury yield, which typically moves in step with interest rate expectations, was last up 1.6 basis points at 0.1728%. A closely watched part of the yield curve, which measures the gap between yields on two- and 10-year Treasury notes , was less than a basis point steeper at 150.36 basis points.
