TOKYO, Jan 27 (Reuters) - Shares tumbled on Monday as investors grew increasingly anxious about the economic impact of China's spreading virus outbreak, with demand spiking for safe-haven assets such as the Japanese yen and Treasury notes.
Japan's Nikkei average .N225 slid 2.0%, the biggest one-day fall in five months, while a Tokyo-listed China proxy, ChinaAMC CSI 300 index ETF 1575.T , slid 2.2%. Amid the Lunar New Year holiday, many markets in Asia were closed.
U.S. S&P 500 mini futures ESc1 were last down 1.0%, having fallen 1.3% in early Asian trade.
European shares were expected to follow suit, with major European stock futures STXEc1 FDXc1 FFIc1 trading 1.2-1.4% lower.
"With most Asian markets closed, fast-money investors are buying risk-off hedges like Treasuries and selling the Nikkei," said Masahiko Loo, portfolio manager at Alliance Bernstein.
"I think this would continue this week, until China markets resume trading next week and the coronavirus outbreak subsides."

Chinese-ruled Hong Kong said it would ban entry to people who have visited Hubei province in the past 14 days. participants kept a wary eye on developments around the virus, which the World Health Organization (WHO) last week deemed "an emergency in China," but not, as yet, for the rest of the world. broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was off 0.4%, although trade in the region has already slowed for the Lunar New Year and other holidays, with financial markets in China, Hong Kong, Taiwan, South Korea, Singapore and Australia closed on Monday.
All three major Wall Street indexes closed sharply lower on Friday, with the S&P 500 seeing its biggest one-day percentage drop in over three months. S&P 500 .SPX lost 0.9%, the Dow Jones Industrial Average .DJI fell 0.6% and the Nasdaq Composite .IXIC shed 0.9% after the Centers for Disease Control and Prevention confirmed a second case of the virus on U.S. soil. Treasury prices advanced, pushing down yields further, with the benchmark 10-year notes US10YT=RR dropping to a 3-1/2-month trough of 1.627% in early Asian trade.

"Investors will react quickly to any sign of negativity and this is no exception as China announces that the issue has become an emergency. This could keep oil prices fragile until the coronavirus shows signs of slowing down," said Mihir Kapadia, chief executive at Sun Global Investments.
