LONDON/SYDNEY, Feb 21 (Reuters) - Shares across the world fell on Friday and were set for their worst week in four as investors dumped riskier assets for the safety of bonds and gold, with coronavirus cases in China and elsewhere spreading.
China reported more cases of the disease on Friday, with finance leaders from the Group of 20 major economies meeting in Saudi Arabia over the weekend set to discuss risks to the global economy stemming from the outbreak. investors have been sanguine about the long term economic risks from the virus, a steady drip of new cases in countries beyond China has kept worries gnawing away, with South Korea on Friday recording over 50 new cases. broad Euro STOXX 600 .STOXX fell 0.3%, with indexes in London .FTSE and Paris .FCHI down 0.5% and 0.3% respectively.
"It's risk-off - bonds are being bought again and hedges are being put into play at the moment," said Olivier Marciot, investment manager at Unigestion.
Not helping the nerves were manufacturing surveys underscoring the grim state of the Japanese economy.
Japan's purchasing managers' index dropped to 47.6 in February, from 48.8, marking the steepest contraction in seven years. surveys painted a somewhat brighter picture, with French business activity growing faster than expected in February on a rebound in the service sector. Germany's private sector expansion also held steady. numbers were due out at 0930 GMT.
Gold and U.S. bonds were among the main beneficiaries as funds sought safety.
Yields on 30-year U.S. Treasuries US30YT=RR fell below the psychologically important 2% level to the lowest since September 2019.
Yields on 10-year notes US10YT=RR were down 9 basis points for the week at 1.498%, lows last seen in September.
Ten-year German government bond yields fell to a four-month low DE10YT=RR , with the entire yield curve on the cusp of turning negative. The entire Dutch yield also returned to negative territory.
Gold was last up 0.8% at $1,631.16 XAU= , having added 3.1% for the week so far to seven-year highs.
"U.S. and EU equity markets have been sold across the board with core global yields benefiting from safe-haven flows," said Rodrigo Catril, a senior FX strategist at NAB.
Underscoring the economic impact from the coronavirus, the International Air Transport Association (IATA) estimated losses for Asian airlines alone could amount to almost $28 billion this year, with most of that in China.
Corporate earnings are increasingly under threat as U.S. manufacturers, like many others, scramble for alternative sources as China's supply chains seize up. MSCI world equity index .MIWD00000PUS , which tracks shares in 49 countries, fell 0.2%, while MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS slipped 1%.
E-Mini futures for the S&P 500 ESc1 slipped 0.3%.
YEN RALLIES
The flows into bonds have been a boon to the U.S. dollar, boosting it to multi-month peaks against a raft of competitors this week.
The most spectacular gains had come on the Japanese yen, as a run of dire domestic data stirred talk of recession there and ended months of stalemate in the market.
Still, the yen rallied on Friday, gaining 0.5% against the dollar JPY= in European trading to 111.51 though the greenback was still set for its best week since July 2018 with a rise of 1.7%.
"It was too soon to write off the yen as a safe haven," said Mayank Mishra, an FX strategist at Standard Chartered (LON:STAN) in Singapore. "I think the yen is reasserting its status as a safe haven."
The dollar against a basket of currencies was last down 0.2% at 99.649, but still near 33-month highs touched a day earlier.
Another casualty of its close trade ties with China was the Australian dollar, which plumbed 11-years lows AUD=D3 .
The euro fared little better at $1.0811 EUR= , having reached depths not seen since April 2017.
Against a basket of currencies, the dollar hit a three-year top at 99.910 =USD having climbed 0.5% for the week so far.
Oil prices fell around 1%, with Brent crude LCOc1 futures easing 78 cents to $58.54.
