* European shares hit lowest in nearly 4 years

* U.S. stock futures down

LONDON, March 12 (Reuters) - Global stocks plunged into a bear market and oil slumped on Thursday after U.S. President Donald Trump banned travel from Europe to stem the coronavirus, threatening more disruption to the world economy.
With the pandemic wreaking havoc on the daily life of millions, investors were also disappointed by the lack of broad measures in Trump's plan to fight the pathogen, prompting traders to bet on further aggressive easing by the Federal Reserve.
"He (Trump) did not announce any new concrete measures such as a large-scale payroll tax cut to buffer the economy against the impending coronavirus slowdown," said Jeffrey Halley, senior market analyst at OANDA.
"That has probably disappointed markets more than anything."
European shares plummeted to their lowest in almost four years, with the benchmark STOXX 600 index falling 4.9% in early deals. Travel and leisure stocks shed 8.6%, hitting their lowest in more than 6 years.
The falls pushed the MSCI All-Country World Index, which tracks stocks across 49 countries, into bear market territory, down 20% from its 52-week peak.
The index was down nearly 2% on the day.
Investors also rushed to safe-haven assets from bonds to gold to the yen and the Swiss franc.
U.S. S&P 500 futures plummeted as much as 4.9% in Asia and last traded down 4.07 , a day after the S&P 500 lost 4.89%, leaving the index on the brink of entering bear market territory, defined as a 20% fall from a recent top.
Those fears left a trail of red across many markets.
Japan's Nikkei crumbled 4.4% to a trough last seen almost three years ago while MSCI's broadest index of Asia-Pacific shares outside Japan fell 4.7%.
Australian shares plunged 7.4% to the lowest level in more than three years while Seoul's Kospi fell 4.8% to 4-1/2-year lows with massive selling prompting a brief trade halt. Thai shares sank 8.8% to 8-year lows.
Trump announced on Wednesday the United States will suspend all travel from Europe, except from Britain, to the United States for 30 days starting on Friday. However, Trump said trade will not be affected by the restrictions.
He also announced some other steps, including instructing the Treasury Department to defer tax payments for entities hit by the virus.
"The travel ban from Europe has definitely taken everyone by surprise," said Khoon Goh, head of Asia Research at ANZ in Singapore.
"Already we know the economic impact is significant, and with this additional measure on top it's just going to multiply the impact across businesses. This is something that markets had not factored in ... it's a huge near-term economic cost."
In the money market, traders further raised expectations of another U.S. rate cut, even after the Fed's emergency cut last week.
Fed fund rate futures are now pricing in a large possibility of a 1.0 percentage point cut, rather than 0.75, at a policy review on March 17-18.
The World Health Organization (WHO) described the outbreak as a pandemic for the first time on Wednesday.
The highly infectious disease that shut down most of China for much of February is spreading rapidly in Europe and increasingly in the United States, disrupting many corners of life from education to sports, entertainment and dining.
Investors worry how much of an effect policies can have in turning around the global economy given the restrictions on daily life, travel and business.
A case in point was Britain, where the FTSE stock index hit near four-year lows on Wednesday as investors doubted whether the $39 billion spending plan and the Bank of England's 0.5 percentage point rate cut announced on Wednesday would be enough to counter the shock from the outbreak.
The index fell even further on Thursday, down 6.25%.
The British pound last stood at $1.2792, down 0.16% on the day.
Safe-haven assets were back in favour.
Gold edged up half a percent to $1,641.71 per ounce but still stood well below Monday's high above $1,700.
The 10-year U.S. Treasuries yield fell to 0.7442% , though it is still above a record low of 0.318% touched on Monday.
The two-year yield fell to 0.4314%, but stood well above Monday's low of 0.251%.
In commodities, oil prices were hit by an intensifying price war between Saudi Arabia and Russia, on top of fears of a sharp slowdown in the global economy.
The United Arab Emirates followed Saudi Arabia in promising to raise oil output to a record high in April.
U.S. West Texas Intermediate (WTI) crude shed 4.94% to $31.35 per barrel.
Copper, seen as a gauge of global economic health because of its wide industrial use, fell to over three-year lows.
In the currency market, the dollar slid against the safe-haven yen and the Swiss franc.
The U.S. currency fell 0.8% to 103.63 yen and lost 0.14% to 0.9366 franc.
The euro traded at $1.1265, down 0.04% ahead of the European Central Bank's policy meeting later in the day.
The ECB is all but certain to unveil new stimulus measures, including new, ultra-cheap loans for banks to pass onto small and medium-sized firms. (Reporting by Ritvik Carvalho; Additional reporting by Hideyuki Sano in Tokyo; Editing by Andrew Cawthorne)
