LONDON, Aug 8 (Reuters) - The dollar raced to a five-month high against the euro on Friday as worries about the euro zone economy mounted, while oil prices slid below $118 a barrel on diminishing supply concerns.
European stocks were flat with automotive firms benefiting from the stronger dollar but energy companies like BP <BP.L> pressured by the fall in oil prices.
A worse-than-expected second quarter loss from Fannie Mae <FNM.N>, the largest U.S. home funding source, weighed on U.S. stock futures <SPc1><DJc1><NDc1>, which pared early gains.
The stronger dollar was also a negative for commodities, knocking more than 2 percent off copper <MCU3=LX> to take it to a six-month low.
Oil dipped below $118 a barrel after an indication that a key oil pipeline through Turkey, still burning after an explosion, may reopen earlier than previously expected, while gold <XAU=>, often seen as an inflation hedge, briefly fell below $860 an ounce to an eight-week low.
"The dollar is driving metals lower," said John Meyer, an analyst at Fairfax Investment Bank.
Data showing Italy's economy shrank in the second quarter cast a shadow over the euro zone, and came a day after European Central Bank President Jean-Claude Trichet highlighted risks to growth, even though he reiterated his concerns about inflation.
Trichet's comments were interpreted by markets as dovish, sparking a steep fall in bond yields as markets priced out the risk of another interest rate hike this year.
"There's going to be more speculation of ECB rate cuts later this year," said Gerhard Schwarz, head of global equity strategy at UniCredit in Munich.
The pan-European FTSEurofirst 300 index <
> edged down 0.1 percent, with Germany's DAX < > and London's FTSE < > both falling about 0.5 percent.MSCI main world equity index <.MIWD00000PUS> was down 0.8 percent.
Royal Bank of Scotland <RBS.L> posted a first half loss was 691 million pounds ($1.3 billion), which although not as bad as feared, kept the sector's woes firmly in the spotlight.
DOLLAR SHINES
The dollar surged more than 1 percent against a basket of major currencies <.DXY>, reaching highs last seen in late February and on track for its biggest weekly rise in 3-1/2 years, while the euro <EUR=> slid below $1.51 -- its lowest in more than five months.
"Our assessment continues to be that the markets have over-interpreted ECB dovishness and there is a serious risk of a EUR/USD bounce should any of the governing council members stress this in the coming days," said RBS global head of forex strategy, Adam Cole.
According to interest rate futures, investors are no longer expecting a euro zone interest rate hike this year.
The two-year Schatz yield <EU2YT=RR> fell to a session low of 4.025 percent, well below the ECB's benchmark 4.25 percent rate, while the 10-year Bund yield <EU10YT=RR> touched a low of 4.236 percent.
"After having been bullish on European bonds for the past couple of weeks, we're turning neutral at these levels. In particular, I can't see the two-year yield going lower," said Cyril Beuzit, head of interest rate strategy at BNP Paribas. (Editing by Mike Peacock)
