(Updates yields, adds analyst comments)
    By Karen Brettell and Karen Pierog
    April 12 (Reuters) - Smooth auctions of three- and 10-year
notes 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.
    The benchmark 10-year yield was last up nearly a
basis point at 1.6746%, holding below a 14-month high of 1.776%
reached on March 30. The three-year yield was last
1.9 basis points higher at 0.3549%. 
    "The 3-year and 10-year Treasury auctions were generally
non-events for markets," said Bill Merz, chief fixed income
strategist at U.S. Bank Wealth Management. "Investors were
watching for signs of weak demand, but slightly higher yields
leading up to the auctions gave investors adequate compensation
for taking down the new supply."
    The $38 billion auction 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.
    Meanwhile, $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..
    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
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," said Jim Vogel, senior rates
strategist at FHN Financial in Memphis, Tennessee.
    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 flatter at 150 basis
points.
