HONG KONG, July 30 (Reuters) - Global stocks rose on Wednesday as investors wagered that the worst news from U.S. banks might be over and took heart from a strengthening dollar and falling oil prices.
Regional share markets reversed Tuesday's falls after reassessing Merrill Lynch's <MER.N> $5.7 billion write-down and share sale as a signal of a turning point in the credit crisis.
Financial bookmakers expected major European markets to rise as well, with London's FTSE 100 <
> seen opening up as much as 1 percent, the German DAX < > as much as 0.8 percent and the French CAC 40 < > as much as 0.9 percent.Among Europe's likely gainers was top global steelmaker ArcelorMittal <ISPA.AS> <MTP.PA>, which unveiled a second-quarter net profit of $5.84 billion, smashing the consensus forecast.
Despite ballooning prices for iron ore and coal, Arcelor's huge profit, following a similar surprise at U.S. Steel <X.N> on Tuesday, shows steelmakers have passed price rises on to consumers, regardless of slowing economic growth. Arcelor's results helped boost shares in Asian competitors Tata Steel <TISC.BO> and POSCO <005490.KS> more than 5 percent.
Japan's Nikkei average <
> closed up 1.6 percent, led by Matsushita Electric Industrial Co <6752.T>, which gained 5.5 percent on the back of strong earnings.Stocks elsewhere in Asia, gauged by MSCI's index, rose 1.5 percent <.MIAPJ0000PUS> by 0650 GMT, with a strong showing from Australia's benchmark S&P/ASX 200 index <
>, which rose 1.8 percent as bank stocks rebounded from this weeks sharp falls.Hong Kong's Hang Seng <
> rose more than 2 percent, helped by Chinese oil refining giant Sinopec <0386.HK>, which gained almost 6 percent after a Reuters report that it had received a $4.4 billion subsidy to offset a first-half refining loss.The high price of oil has spurred inflation, troubled oil refiners and savaged airlines around the world this year, so a $25 slump in crude prices over the last two weeks towards three-month lows has brought some respite to equities.
U.S. crude oil <CLc1> hovered around $122 a barrel on Wednesday, reflecting mounting evidence that high prices and a souring U.S. economy were cutting into energy demand. Buyers struggled to put a floor under their steepest slide in a year and a half.
"The reason prices are coming off is that there are expectations for inventory builds... on reduced demand," said Robert Nunan, a risk management executive at Tokyo-based Mitsubishi Corp.
The weakening oil price has been bolstered by the dollar, which was steady near Tuesday's one-month high of about 108.30 yen <JPY=>, with an unexpected rise in U.S. consumer confidence offsetting a steeper-than feared fall in Japanese industrial output.
The U.S. dollar index <.DXY>, which measures the dollar's performance against a basket of six currencies, firmed up to 73.360, nearing its highest level in about a month.
The U.S. currency could extend gains if more economic data this week further assuage market concerns about the economy falling into a recession, traders say.
Investors will closely watch the ADP national employment survey due later in the day to help reassess forecasts for key U.S. jobs numbers due out on Friday.
"The market has been altering excessively pessimistic views about the U.S. economy," said Hideaki Inoue, chief manager of forex trading at Mitsubishi UFJ Trust Bank.
"Key data this week such as the second quarter growth data and the jobs report later in the week could encourage some investors to shift funds back into the dollar, though it depends on the outcome," said Inoue.
Trade in Japanese government bonds was subdued as attention turned to the U.S. data.
The 10-year yield slipped to 1.525 percent, touching Tuesday's three-month low, with some investors looking to buy bonds before another anticipated fall in yields. But traders said others were biding their time in case positive stock market sentiment pushes yields up.
