* Fed keeps rates steady, to start portfolio drawdown in October
* Fed statement suggests it still anticipates Dec rate hike
* Treasury yields jump to highest in 6 weeks
* Wall St falls after Fed signals another rate hike this year (Updates to after Fed statement)
NEW YORK, Sept 20 (Reuters) - U.S. Treasury yields rose, the dollar gained while U.S. stocks fell on Wednesday after the U.S. Federal Reserve signaled it expects one more interest rake hike by the end of the year.
In its statement, the Fed, as expected, left rates unchanged and also said it would begin in October to reduce its approximately $4.2 trillion in holdings of U.S. Treasury bonds and mortgage-backed securities.
Benchmark U.S. Treasury yields jumped to their highest levels in six weeks. Benchmark 10-year notes fell 11/32 in price to yield 2.29 percent, up from 2.24 percent before the Feds statement and the highest level since Aug. 8.
The reaction in the Treasury market "suggests a lot of people maybe weren't anticipating the Fed would stick with the third rate hike expectation this year. So there's a little adjustment going on there," said David Joy, chief market strategist at Ameriprise Financial in Boston.
Interest rate futures traders are now pricing in a 72-percent chance of a December rate hike, up from roughly 60 percent before the statement, according to the CME Group's FedWatch Tool.
Financial shares added to gains following the statement while utilities declined.
The Dow Jones Industrial Average rose 7.97 points, or 0.04 percent, to 22,378.77, the S&P 500 lost 2.64 points, or 0.11 percent, to 2,504.01 and the Nasdaq Composite dropped 21.76 points, or 0.34 percent, to 6,439.57.lost 0.09

The dollar index rose 0.75 percent, with the euro down 0.83 percent to $1.1892.
Stocks had been mostly flat ahead of the Fed statement, while the dollar had been trading slightly lower.
Earlier, the New Zealand dollar hit its strongest in more than a month at $0.7374 after a poll showed the ruling National Party regaining a wide lead over the opposition before Saturday's election.
