TREASURIES-U.S. yields rise as CPI data bolster Dec rate-hike view

* U.S. consumer prices post biggest rise in seven months in August

* Futures imply traders now see Dec rate hike back up to 50 pct

* U.S. yield curve moves to flattest level in over two weeks

(Updates market action, adds quote) NEW YORK, Sept 14 (Reuters) - U.S. Treasury yields rose on Wednesday, with the two-year yield hitting a seven-week peak as domestic consumer prices grew at their briskest pace in seven months, rekindling bets the Federal Reserve would raise interest rates for a third time in 2017. Longer-dated yields rose less than their short-dated counterparts, reflecting the view that the Fed's pace of raising short-term rates would be faster than underlying inflation trend. "The number came in higher than expected. It gives the Fed a little more room to raise rates on the short-end," said Justin Hoogendoorn, head of fixed income strategy and analytics at Piper Jaffray in Chicago. The consumer price index, the government's broadest inflation gauge, rose 0.4 percent in August, faster than the 0.3 percent increase forecast among analysts polled by Reuters. That lifted the CPI's year-over-year increase to 1.9 percent from 1.7 percent in July. But the so-called core CPI, which excludes volatile energy and food prices, rose 1.7 percent on a 12-month basis and remained stuck below the Fed's 2 percent goal for underlying inflation. "In the long term, we see slower business activities and inflation expectations coming down," Hoogendoorn said. Still, the latest CPI data revived expectations the U.S. central bank may consider hiking interest rates at its Dec. 12-13 meeting if subsequent data support the case that inflation is accelerating. Interest rates futures implied traders saw more than a 50 percent chance of rate increase in December, the highest since July, based on data from CME Group's FedWatch program. . The U.S. central bank raised key short-term rates in March and June. Its current target range has been 1.00-1.25 percent. Fed policymakers will meet on Sept. 19-20 and are expected to leave rates unchanged and announce their plan to reduce the central bank's $4.2 trillion holdings of Treasuries and mortgage-backed securities. At 1:25 p.m. (1725 GMT), the yield on two-year Treasury notes, which is sensitive to traders' view on Fed policy, was up 2 basis points at 1.372 percent. It touched 1.388 percent earlier on Thursday, which was its highest since July 26, Reuters data showed. The benchmark 10-year yield hit a three-week peak at 2.225 percent before retreating to 2.202 percent, up 0.7 basis point from late on Wednesday. The yield spread between five-year and 30-year Treasuries shrank to 99 basis points, the tightest in about 2-1/2 weeks, according to Tradeweb. September 14 Thursday 1:42PM New York / 1742 GMT Price
