NEW YORK, Sept 25 (Reuters) - The dollar sank to a 7-1/2-month low beneath the key 90-yen level on Friday after the G20 pledged to keep up emergency stimulus spending until a recovery takes hold, suggesting U.S. interest rates would remain very low.
The yen got a boost after Finance Minister Hirohisa Fujii and an influential former finance official suggested separately that authorities were not inclined to halt the currency's rise. For details, see [
]Analysts also said investors repatriating funds before Japan's fiscal year hits the halfway mark on Sept. 30 also lifted the yen.
"The comments suggesting Japan is more comfortable with a strong yen helped, but it's also a capital flow story with a lot of money coming back at midyear," said Greg Salvaggio, vice president of trading at Tempus Consulting in Washington.
The dollar was last down 1.6 percent at 89.80 yen <JPY=> after hitting 89.52 yen earlier, the lowest since February. The euro also fell 1.5 percent to 131.84 yen <EURJPY=>.
The dollar fared better against sterling, which fell to multi month lows a day after Bank of England Governor Mervyn King said a weak pound would help exports and the UK economy.
But the euro edged higher against the greenback, helped by encouraging data showing that U.S. consumer sentiment hit its highest level this month since January 2008. [
]The euro rose 0.1 percent to $1.4680 <EUR=>, boosted after encouraging U.S. consumer sentiment data and a separate report showing U.S. new homes sales edged up in August.
The dollar suffered after a draft G20 statement obtained by Reuters showed that leaders from the leading rich and developing countries intend to maintain emergency support until their economies recover and then work together to scale back spending. [
]Investors said that means interest rates are likely to remain low, with record low U.S. rates keeping the dollar under pressure.
"The cyclical argument has not changed to favor the dollar," said Michael Klawitter, senior currency strategist at Commerzbank in Frankfurt.
While many in the market believe a U.S. rate rise is also far off, Federal Reserve Board Governor Kevin Warsh said on Thursday the U.S. central bank may have to raise rates before the need to take action becomes obvious.
That helped the dollar overnight, though the gains faded before North American trading got underway. [
]The pound <GBP=D4> fell to $1.5917, its lowest since early June, before edging back to $1.5974, down 0.6 percent. It sank against the yen <GBPJPY=R>, falling as low as around 144.30 yen, its weakest since mid-May, while the euro rose above 92 pence <EURGBP=> for the first time since April.
King's comments hit the currency, as did perceptions that the Bank of England will lag other central banks in ending its loose monetary policy.
