LONDON, Sept 4 (Reuters) - The dollar was little changed on a trade-weighted basis on Friday ahead of U.S. employment figures that could set the tone for the greenback -- and other financial markets -- for the rest of the month.
Trading ranges across major currency pairs were tight in Europe, with investors reluctant to put on big positions ahead of the August non-farm payrolls data. <ECON>
The euro recovered some of its losses the previous day triggered by comments from European Central Bank President Jean-Claude Trichet suggesting the outlook for growth, inflation and credit conditions will keep policy and therefore market interest rates low for some time.
And the dollar inched back up from its seven-week low against the yen struck earlier this week, supported by gains in European equity markets, U.S. stock futures and two-year U.S. Treasury bond yields.
"There's been a degree of recovery in risk appetite ... and and there's been a very strong interest from (Japanese) importers to buy dollars at these low levels," said Derek Halpenny, senior currency economist at BTM-UFJ in London, referring to dollar/yen.
The focus is firmly on the U.S. dollar and how it reacts to the U.S. jobs figures. A weaker-than-expected report may trigger dollar selling or alternatively burnish the currency's safe-haven status in a climate of rising risk aversion.
"The episode will be critical in judging the extent to which the expected regime switch, from risk cycle to business cycle trading, is proceeding. We expect the dollar to strengthen once market focus shifts to the likely outperformance of the U.S. economy," Citigroup strategists said in a note on Friday.
At 1113 GMT, the dollar index was little changed on the day at 78.36 <.DXY>.
The dollar was up 0.2 percent against the yen at 92.80 yen <JPY=>, rebounding further from Thursday's seven-week low just under 92.00 yen, and the euro was up 0.3 percent at 132.45 yen <EURJPY=R>.
But it fell nearly 1 percent on the day against the Canadian dollar, which rallied as high as C$1.0922 <CAD=D4> following an unexpected rise in employment in Canada in August. [

OPTIONS OVERLOAD
Traders noted dollar/yen options expiries worth over $1 billion later on Friday, including strikes worth $800 million at 91.60 yen.
The euro was flat at $1.4260 <EUR=>, capped by good technical-related selling at the 100-day moving average of $1.4282 and options-related selling ahead of large expiries later in the day at $1.4300.
There are also large euro/dollar options strikes at $1.4400 rolling off after the U.S. jobs data on Friday, traders said.
"It's a very large expiry list today, probably the biggest of the year so far ... so this might start to have the 'magnet effect' on spot if payrolls does not surprise either way," said one trader in London.
The latest forecast is for a drop of 225,000 in payrolls with the jobless rate inching up to 9.5 pct [
]. But estimates range from a fall of 100,000 to a 365,000 decline.Other areas of focus included the meeting in London this weekend of finance ministers from the Group of 20 rich and developing nations.
G20 policymakers will promise to keep economic support packages in place until recovery is certain and seek to reassure financial markets they have credible plans to withdraw the stimulus when appropriate. [
]This was a theme stressed by Trichet on Thursday after the ECB kept interest rates at a record low 1.0 percent.
His announcement that the rate at the ECB's tender of unlimited one-year funds later this month would be kept at 1 percent [
] pushed down short-term rates and yields, and steepened the yield curve.Trichet said in a speech in Frankfurt on Friday that the ECB could raise rates before it fully exits its non-standard liquidity provisions, although now was not the time to start such an exit strategy [
