LONDON, July 4 (Reuters) - European shares fell early on Friday, as relief over interest rates quickly evaporated and bearish brokerage comment weighed on banks, though UBS <UBSN.VX> gained after saying it expected at worst a small quarterly loss.
At 0826 GMT, the FTSEurofirst 300 <
> index of top European shares was down 0.8 percent at 1,168.86 points. United States markets will be closed for the Independence Day holiday.Banks were broadly weaker after Goldman Sachs cut its rating on Spain's Santander <SAN.MC> to "neutral" from "buy" and took down price targets for Deutsche Bank <DBKGn.DE>, Commerzbank <CBKG.DE> and Deutsche Postbank <DPBGn.DE>.
Santander ranked among the top negative weights on the index with a 2.5 percent fall, while Deutsche Bank, Commerzbank and Deutsche Postbank fell 1-1.9 percent.
But UBS gained 3 percent after saying a large tax credit should help to save it from another hefty loss in the second quarter.
European shares rose on Thursday after the European Central Bank raised rates by 25 basis points as expected but indicated that no further moves were imminent.
"The rate decision was a short-term positive as the wording of the statements was not hawkish as expected. Clearly the ECB needs to see inflation expectations building and second-round effects before they hike again," said Gerhard Schwarz, head of global equity strategy at UniCredit in Munich.
"But we cannot get any big relief as long as the overall stagflation fears hang over the market, and the oil price is a major factor in this. There will be a wave of downward pressure on equities after any recovery," he added.
"The big question on equity markets is: how far will the derating go, and when will valuations find a bottom as we consider inflationary pressures not seen in two and a half decades?"
Oil traded at around $145 a barrel, within striking distance of its all-time high of $145.85 hit on Thursday.
Across Europe, Britain's FTSE 100 <
> fell 0.8 percent, Germany's DAX < > fell 0.5 percent and CAC 40 < > lost 0.7 percent.
MORE CAPITAL RAISINGS?
Goldman lowered 2008-09 estimates for over 40 banks, saying that the sector was weighed by the risk for additional capital raisings.
It said in a note that the European banking sector may need to raise 60-90 billion euros, noting that banks that had recently recapitalised had reached an average Tier 1 ratio of around 9 percent and a core Tier 1 ratio of around 6.5 percent.
"If this level represents a new capital standard (self-imposed or more actively encouraged by regulators and rating agencies" we estimate that the sector could need to raise 60 billion euros, or withhold one year of dividends," it said.
"Furthermore, should a turn in the European credit cycle trigger losses in line with those seen in the early 1990s, the sector could need to raise more than 90 billion euros, on our estimates."
Other major losers included Marks & Spencer <MKS.L> which fell 5.3 percent on a Citigroup downgrade, extending weakness after a profit warning on Wednesday.
Mining stocks were generally lower, with BHP Billiton <BLT.L>, Rio Tinto <RIO.L> and Antofagasta <ANTO.L> down 1-2.2 percent as copper prices fell.
But oil stocks, which rose 15 percent in the second quarter to end-June on surging crude prices, were broadly weaker.
Index heavyweight BP <BP.L> fell 0.3 percent, Royal Dutch Shell <RDSa.L> lost 0.5 percent and Total <TOTF.PA> dipped 0.1 percent.
