FTSE seen opening more than 6 pct lower

LONDON (Reuters) - The FTSE 100 .FTSE index is seen opening down as much as 6.7 percent on Friday, according to financial bookmakers, as investors continue to fret about the parlous state of the global banking system.

Asian stocks plunged on Friday with Japan's Nikkei 225 .N225 down nearly 10 percent as jitters intensified and investors shrugged off efforts to unlock credit markets.

A synchronised cut in borrowing costs is being seen as too little, too late and investors are sceptical that a G7 meeting held in Washington can do much to avert impending recession.

Japan's unlisted Yamato Life Insurance Co filed for bankruptcy protection because of market turmoil showing that Asian institutions are not immune from the whirlwind reaped by the credit crisis.

As well as financials, energy stocks will be in focus as oil prices fell $4 to $82.5 a barrel as fears that market turmoil for fuel slumping while miners will also be heavily under pressure once again as base metals prices slid.
