LONDON, June 27 (Reuters) - Oil extended its rally on Friday to a new peak above $142 a barrel while global stocks slumped to three-month lows as investors became increasingly worried about the outlook for corporate profits and inflation.
Wall Street looked set for a cautious start after Thursday's slide that sent the blue-chip Dow <
> skidding to a 21-month low.Fresh data showing surging energy and other raw material costs putting upward pressure on prices from Germany to Japan further spurred investors to cut back on risky trades, helping boost the yen to three-week highs versus the dollar.
"There is a bout of risk reduction across assets ... Oil prices headed up and that's putting more pressure on equities," said Martin McMahon, FX strategist at Credit Suisse in Zurich.
The FTSEurofirst 300 index <
> of top European shares slumped to its lowest level since late October 2005, while the MSCI main world equity index <.MIWD00000PUS> fell 0.6 percent to three-month lows, on track for its worst monthly performance in percentage terms since September 2002.U.S. stock futures <DJc1><NDc1><SPc1> were all lower.
Earlier, Japanese stocks <
> shed 2 percent to a two-month closing low while speculation of an imminent interest rate hike in China pushed local shares to a 16-month trough.The latest round of selling in a global stock markets began earlier this week when Goldman Sachs urged investors to sell U.S. bank and automaker shares, forecasting more write-downs for financial firms like Citigroup <C.N>.
U.S. crude <CLc1> rose more than $2 a barrel to a new all-time high of $142.26 on Friday, while gold <XAU=> climbed to a one-month high of $925.30 an ounce as tumbling stocks and a weaker dollar boosted the metal's safe-haven appeal.
Oil prices have doubled from $70 a year ago on supply disruptions and geopolitical tensions in the Middle East, while rising flows of cash into commodities from investors seeking to hedge against inflation and the weak dollar have added to gains.
The dollar fell 0.1 percent against a basket of major currencies <DXY>, having earlier carved out a fresh 3-week low given the gloomy outlook for the U.S. economy. It also plumbed a three-week low of around 106.17 yen <JPY=>.
INFLATION PICTURE WORSENING
Safe-haven government bonds mostly erased early gains, pushing yields slightly higher on expectations that central banks will be forced to lift rates to fight inflation.
The U.S. two-year yield <US2YT=RR> climbed 1 basis point to 2.68 percent, while the two-year Schatz yield <EU2YT=RR> was little changed at 4.43 percent.
Data from five German states so far showed inflation in Europe's biggest economy likely accelerated in June.
Separate reports showed French producer prices posting their biggest jump in almost a decade in May, Spanish consumer inflation hit an 11-1/2 month high in June, while Japan's annual consumer inflation accelerated to a new decade-high of 1.5 percent in May.
The inflation picture is worse in emerging markets, where countries like Vietnam and India are already experiencing double-digit inflation.
"The macroeconomic environment has turned far more challenging for EM policymakers. Slowing growth and accelerating inflation create a tough policy backdrop," Lehman Brothers said in a note to clients.
"Central banks are raising rates and could easily err by being too hawkish or too dovish. There is a rising risk of policy mistakes. Political pressures to intervene in markets are growing, potentially creating long-term distortions and weakening fiscal frameworks."
The European Central Bank is likely to become the first G7 central bank to raise interest rates next week, pushing the cost of borrowing to 4.25 percent. (Additional reporting by Natsuko Waki and Toni Vorobyova)
