* Euro shrugs off record euro zone GDP fall

NEW YORK, Feb 13 (Reuters) - The dollar climbed against the yen on Friday, boosted by bets that Group of Seven finance chiefs may single out the Japanese currency for excessive strength at this weekend's meeting.
The U.S. currency was also bolstered against the yen by optimism about a government program to subsidize mortgages for homeowners even as investors shifted their focus to the gathering of Group of Seven monetary officials in Rome.
"Watch for language from the G7 to support open markets, open trade, and open capital flows," said Andrew Busch, global FX strategist at BMO Captial Markets in Chicago in a note to clients. "However, there's a strong probability that the communique will have a sentence on the Japanese yen and the British pound."
Earlier in the week, Japanese Finance Minister Shoichi Nakagawa said Japan will act decisively against excessive currency moves, but suggested singling out the strong yen in a G7 communique would not work while the damage from the global economic crisis is spreading.
UK Chancellor of the Exchequer Alistair Darling said on Friday that he believed any discussion of foreign exchange would be "in general terms."
Still, traders were not taking any chances.
The yen has edged lower so far in 2009, down about 1.6 percent against the dollar at current prices. But in 2008, the yen, perceived as a safe haven along with the dollar, had rallied 23 percent.
In mid afternoon New York trading, the dollar rose 1.2 percent against the yen to 91.97 yen <JPY=>. The euro also gained, up 1.6 percent at 118.70 <EURJPY=>.
STERLING RALLY
Analysts said the bleak euro zone GDP figures had also raised concerns G7 leaders may discuss the pound's recent weakness against the euro.
In fact, sterling rallied, with investors squaring market positions ahead of the G7. For details, see [
]But the pound came off its highs pressured by sharp falls in UK banking stocks after Lloyds Banking Group unveiled a hefty loss related to its HBOS subsidiary.
Lloyds said HBOS lost about 8.5 billion pounds last year, news which sent shares in Lloyds and other UK banks tumbling and pushed the UK's FTSE share index into the red.
Sterling last traded at $1.4382 <GBP=>, up 0.9 percent. The euro fell 0.5 percent against sterling to 0.8970 <EURGBP=>.
Other analysts though said they do not expect any major pronouncements on the yen and sterling, and once the meeting ends markets will look to equities again for direction.
"We are still hinging on risk appetite and we are keying off equities," said Shaun Osborne, chief currency strategist, at TD Securities in Toronto.
"That story on mortgage subsidy gave equities a lift including the dollar versus the yen and there's still some carry-over from that."
Investors tend to sell the dollar and yen with increased optimism for global economic prospects.
Markets welcomed the news that the Obama administration may unveil a broad plan to put a floor under the housing market. [

The euro rose 0.3 percent <EUR=> against the dollar to $1.2902, generally shrugging off data showing the euro zone economy in a deeper recession than expected.
