LONDON, July 1 (Reuters) - European shares extended losses in early trade as banks weighed amid fears of further losses and as buoyant oil kept inflation as a key focus for investors.
The FTSEurofirst 300 index <
> of top European shares fell 2.0 percent to 1,177.32 points in early trade."There are no reasons to own shares at the moment," said asset manager Stefan de Schutter at Alpha Trading in Frankfurt.
"Oil is still very high and the banking crisis is continuing," he added, noting vague rumours overnight of a profit warning at Lehman Brothers <LEH.N>, which fell 11 percent during regular trading in the United States.
Bank were the biggest drag on indexes in Europe with the DJ Stoxx European banks index <.SX7P> down 2 percent. BNP Paribas <BNPP.PA> fell 2 percent, Societe Generale <SOGN.PA> lost 2.6 percent and UBS slid 4.4 percent.
UBS was also under pressure after Merrill Lynch removed it from its "Europe 1 List". In addition, the U.S. Justice Department said it asked a federal court to authorise the Internal Revenue Service to request information from UBS about U.S. taxpayers who may be using Swiss bank accounts to evade federal income taxes.
Banco Popular <POP.MC> lost 3 percent following a report in newspaper Negocio which said legal advisor Hassans will no longer help Blueprime in its move to buy a 20 percent stake in the Spanish bank.
Airlines were also under pressure as oil rallied back above $141 a barrel with British Airways <BAY.L> down 2.4 percent, Air France-KLM <AIRF.PA> down 1.5 percent and Lufthansa <LHAG.DE> down 1.2 percent.
And automotive stocks were major decliners on European indices, with BMW <BMWG.DE>, Porsche <PEUP.PA> and Renault <RENA.PA> all down between 3 and 5 percent ahead of the release of North American car sales for the month of June.
Around Europe, Britain's FTSE <FTSE> lost 0.9 percent, Germany's DAX <
> shed 0.7 percent and France's CAC lost 1.4 percent.Other major fallers included France's Safran <SAF.PA>, which saw its shares downgraded to "underperform" from "outperform" at Cheuvreux and fell 8 percent.
TELECOMS GAIN GROUND ON BROKER UPGRADES
On the upside, telecoms groups gained with Deutsche Telekom <DTEGn.DE> adding 2 percent after JP Morgan raised its stance on the stock to "overweight", with a target price of 13.50 euros.
"A poorly structured Sprint bid remains a risk, but in our view is becoming increasingly unlikely as the U.S. presidential election approaches," the broker said in a note.
British peer Vodafone <VOD.L> rose 1.7 percent after Exane BNP Paribas raised it to "outperform" as it sees a "more limited perceived M&A risk" and "higher-than-average revenue growth".
