* Higher oil boosts energy shares
* US stocks off as Kuwait scraps venture with Dow Chemical
* Europe, Japan stocks end up, dollar falls, gold gains
By Daniel Bases
NEW YORK, Dec 29 (Reuters) - Violence in the Middle East drove up the price of oil and weakened the dollar on Monday on worries about threats to crude supplies, helping to drive a safe-haven bid for U.S. Treasuries and for gold.
U.S. stocks fell with the scrapping of a $17.4 billion petrochemical joint venture between Kuwait and Dow Chemical, overshadowing a rise in energy shares on the higher oil prices.
European stocks closed higher, however, on advances in energy companies and banks, while Japanese stocks rose after reports of a potential merger of three insurance companies.
"Price action this morning has been driven mainly by a sudden rise in global risk aversion following the attacks in Gaza, which in turn led to a spike in oil and gold," said Matt Esteve, a foreign exchange trader at Tempus Consulting in Washington D.C.
Israeli warplanes pounded the Hamas-ruled Gaza Strip for a third consecutive day on Monday, killing more than 325 people in the deadliest violence in the coastal territory in decades.
Concerns that the violence, which has sparked protests across the Middle East, might impact oil supplies, sent U.S. light sweet crude oil <CLc1> up 35 cents, or 0.93 percent, to $38.06 per barrel. The weaker U.S. dollar also helped lift oil.
"It's a terrible situation and it just seems to be again causing major concerns for all the markets," Peter McGuire, managing director at Commodity Warrants Australia, said of the Gaza violence.
"But where it's going, nobody knows. Who can speculate on war?"
The dollar was down against a basket of major trading-partner currencies in thin holiday conditions. The U.S. Dollar Index <.DXY> was off 0.95 percent at 80.199.
The euro <EUR=> was up 1.17 percent at $1.4225. Against the Japanese yen, the dollar <JPY=> fell 0.57 percent at 90.17.
The dollar shed 2.30 percent against the Swiss franc to trade at 1.0430 <CHF=> on a safe-haven play.
Sterling, however, fell 0.51 percent against the U.S. dollar to $1.4572 <GBP=>. The British pound also fell to a record low against the euro of 97.99 pence <EURGBP=>, as it approached parity for the first time since the euro was launched in 1999.
The slide in the pound came after reports pointed to a further slide in UK home prices in 2009.
Figures showed housing prices in England and Wales fell 8.7 percent in 2008 with the onset of recession and the prospect of rising unemployment over 2009 likely leading to further declines. (For more, click on [
