HONG KONG, June 19 (Reuters) - Asian stocks slid on Thursday, after Wall Street closed at a three-month low, sparking fears of a pullback in export demand with oil prices remaining high and feeding a rally in safe-haven government bond prices.
The U.S. dollar was down for a fourth straight day against major currencies as expectations for higher interest rates from the Federal Reserve continue to be doused by evidence the U.S. economy may not have hit bottom yet.
Japan's Nikkei share average <
> tumbled 2 percent in early trade, leading the region lower and bringing the year's losses to 7.5 percent. Car makers such as Honda Motor Co <7267.T> and Toyota Motor Corp <7203.T>, which are sensitive to fluctuations in fuel prices, were among the biggest weights on the index."Exports support Japan's economy and there's no way Japan won't be affected. Shanghai and Vietnamese stocks are already eroding," said Takahiko Murai, general manager of equities at Nozomi Securities in Tokyo.
Shares elsewhere in the Asia-Pacific region fell 1.1 percent, snapping a three-day string of gains and bringing the year-to-date decline to 15 percent, according to an MSCI index <.MIAPJ0000PUS>.
Shanghai stocks <
> eased 1.3 percent in early trade and are now down 45 percent this year, while Vietnam's small market < > fell a further 2.4 percent to take year-to-date losses to 60 percent.In South Korea, consumer technology heavyweight Samsung Electronics <005930.KS> led the KOSPI <
> 1.4 percent lower. Samsung's stock fell more than 3 percent after a Taiwanese paper report that some of the company's chips had problems.NOT ALL NEGATIVE
The picture of Asia was not altogether bleak though.
JPMorgan Chase upgraded China to overweight in its model Asian and emerging market portfolios based on the view that a stronger yuan will help to contain inflation as Beijing shifts from managing price pressures to stoking growth.
"Even without a lower oil price, China arguably has the greatest policy flexibility to manage inflation," said Adrian Mowat, Asian equity strategist with JPMorgan, in a note.
Indeed, the yuan <CNY=CFXS> was trading at its strongest against the dollar since being revalued in July 2005, up more than 6 percent since the year began.
The U.S. dollar slipped 0.15 percent to 107.65 yen <JPY=>, while the euro rose 0.2 percent to $1.5558 <EUR=>.
The New York Board of Trade's dollar index, a measure of the U.S. currency's value against a basket of six major currencies, was down 0.1 percent at 73.321 <.DXY>. The index hit its highest since late February on Friday but has since declined as expectations of aggressive rate hikes from the Federal Reserve fade.
"The market has been reminded about weak elements in the U.S. economy and feels hesitant now about buying the dollar," said a trader at a Japanese trust bank.
Worries about the U.S. economy and lingering credit concerns also weighed on U.S. stocks overnight, with major indexes down 1 percent or more. [
]Central bankers around the world have been struggling to balance higher inflation with the need to spur sluggish economic growth, as housing markets continue to deteriorate, consumers become more pessimistic and commodity prices climb ever higher.
Oil prices were a touch lower, with U.S. crude futures for July <CLc1> down 0.3 percent to $136.21 a barrel, though were within striking distance of the record of $139.89 hit on Monday.
Food inflation was almost certainly headed higher, with U.S. corn futures up for the 12th consecutive session, following the worst floods in 15 years in the American agricultural heartland. [
