SYDNEY, Nov 29 (Reuters) - Asian markets regained a little composure on Monday as investors settled in for a few weeks of uncertainty on whether the Omicron variant would really derail economic recoveries and the tightening plans of some central banks. Oil prices also bounced $3 a barrel to recoup some of Friday"s shellacking, while the safe haven yen took a breather after its run higher. The new variant of concern was found as far afield as Canada and Australia as more countries imposed travel restriction to try to seal themselves off. read more Britain called an urgent meeting of G7 health ministers on Monday to discuss developments on the virus, although a South African doctor who had treated cases said symptoms of Omicron were so far mild. "There is a lot we don"t know about Omicron, but markets have been forced to reassess the global growth outlook until we know more," said Rodrigo Catril, a market strategist at NAB. "Pfizer expects to know within two weeks if Omicron is resistant to its current vaccine, others suggest it may take several weeks. Until then markets are likely to remain jittery." Trading was erratic early on Monday but there were signs of stabilisation as S&P 500 futures added 0.8% and Nasdaq futures 0.9%. Both indices suffered their sharpest fall in months on Friday with travel and airline stocks hit particularly hard. MSCI"s broadest index of Asia-Pacific shares outside Japan (.MIAPJ0000PUS) eased 0.1% but was off early lows. Likewise, Japan"s Nikkei (.N225) pared early losses to be down 0.9%. Bonds gave back some of their gains, with Treasury futures down 11 ticks. The market had rallied sharply as investors priced in the risk of a slower start to rate hikes from the U.S. Federal Reserve, and less tightening by some other central banks. Two-year Treasury yields edged up to 0.55%, after falling 14 basis points on Friday in the biggest drop since March last year. Fed fund futures had pushed the first rate rise out by a month or so. The shift in expectations undermined the U.S. dollar, to the benefit of the safe haven Japanese yen and Swiss franc. Early Monday the dollar had steadied somewhat at 113.81 yen , after sliding 1.7% on Friday. The dollar index held at 96.190, after Friday"s 0.7% drop. The euro paused at $1.1294 , following its rally from $1.1203 late last week. European Central Bank President Christine Lagarde put a brave face on the latest virus scare, saying the euro zone was better equipped to face the economic impact of a new wave of COVID-19 infections or the Omicron variant. read more The economic diary is also busy this week with China"s manufacturing PMIs on Tuesday to offer another update on the health of the Asian giant. The U.S. ISM survey of factories is out on Wednesday, ahead of payrolls on Friday. Fed Chair Jerome Powell and Treasury Secretary Janet Yellen speak before Congress on Tuesday and Wednesday.

Brent rebounded 3.9% to $75.57 a barrel, while U.S. crude rose 4.5% to $71.24. Gold has so far found little in the way of safe haven demand, leaving it stuck at $1,791 an ounce .
