(Adds close of U.S. markets)
By Herbert Lash
NEW YORK, May 7 (Reuters) - Oil prices shot further into record territory on Wednesday, topping $123 a barrel, stoking inflation fears and sending U.S. stock markets spiraling lower, with the Dow industrials slumping more than 200 points.
Remarks from a Federal Reserve official warning that the central bank must be ready to raise interest rates to curb inflation also pressured stocks, led by declines in financial shares.
The president of the Kansas City Fed, Thomas Hoenig, in a speech late on Tuesday called the inflation outlook "troublesome," and his remarks increased expectations that the U.S. central bank's cycle of aggressive interest rate cuts may be nearing an end.
The dollar gained after Hoenig's remarks.
U.S. Treasury debt prices hit session highs as stocks extended losses on resurgent oil prices, which fueled worries that soaring energy costs will crimp the consumer and hobble the overall economy, increasing the safe-haven appeal of government bonds.
"Inflation is definitely a worry because the Fed doesn't have that much to fight inflation except by raising interest rates," said Alan Lancz, president of investment adviser Alan B. Lancz & Associates Inc in Toledo, Ohio.
"If the economy is not growing the way they want, raising interest rates all adds up to a difficult environment," he said.

Earlier in Europe, shares notched their highest close since mid-January, helped by a weaker euro and results at construction and technology groups that beat expectations.
U.S. and European equity markets got an initial lift from U.S. government data that showed higher-than-expected worker productivity gains and a lower-th`n-expected rise in unit labor costs, which soothed some inflation fears.
But pending U.S. home sales fell in March, as expected, and provided little upside for investors.
In Europe, the pan-European FTSEurofirst 300 index <
> rose 0.8 percent at 1,362.11 points, its highest point since mid-January.The technology sector <.SX8P> was the best performer in Europe after Cisco Systems <CSCO.O>, the largest U.S. maker of routers and switches that direct Internet traffic, reported better-than-expected quarterly results late on Tuesday.
Nokia <NOK1V.HE>, Ericsson <ERICb.ST> and ASML <SML.AS> gained about 4 percent.
Strong profits at French cement maker Lafarge <LAFP.PA> lifted constructions stocks.
In the commodities market, oil at first eased after figures from the U.S. Energy Information Administration showed crude oil inventories rose 5.7 million barrels last week, more than analysts' consensus estimates of 1.6 million barrel increase.
But distillate inventories, including heating fuel and diesel, dropped by 100,000 barrels to 105.7 million barrels, against analysts' expectation of an 800,000 barrel increase.
"Traders were trying to comb the EIA data for any bullish feature and they found it in distillates," Jim Ritterbusch, president of Ritterbusch & Associates, said.
Traders also remained concerned about supply disruptions in Nigeria. Also, concerns surfaced over supplies from Iran, the world's No. 4 oil producer, when Tehran earlier this week said it would refuse nuclear inspections.
IN addition, the head of the state-run company of OPEC member Libya said oil prices would rise further.
U.S. crude <CLc1> leapt $1.69 to settle at $123.53 a barrel after hitting an all-time peak of $123.80, the third record this week. London Brent <LCOc1> rose $2.01 to $122.32.
Crude prices have doubled in the past year, weighing on economies already hard hit by a housing slump and a credit crisis that weakened U.S. growth and is spreading to Europe.
The dollar gained, bolstered by comments by the Fed's Hoenig late on Tuesday that rates will need to be raised in a timely way as the central bank grapples with a serious threat of inflation.
The euro fell on reports showing euro zone retail sales were much weaker than expected, while German manufacturing orders unexpectedly fell by 0.6 percent in March -- underlining concerns about slowing economic growth in the region.
A run of poor economic data -- France reported a record trade deficit for March -- has pressured the euro in recent weeks after it hit a record high above $1.60, peeling away perceptions the euro area was insulated from a U.S. downturn.
The dollar rose against major currencies, with the U.S. Dollar Index <.DXY> up 0.66 percent at 73.477.

U.S. gold futures closed down but off session lows as a late surge in crude prices to record highs helped offset a firmer dollar.
