LONDON (Reuters) - World stocks and oil were knocked hard on Thursday after global manufacturing data and an Ebola health scare in the United States spooked markets, sending investors scurrying to the safety of U.S. bonds, the yen and gold.
European markets had been sucked into the storm, anxious about the European Central Bank's monthly meeting where it is under pressure to launch an aggressive government bond purchase program to revive the euro zone's stodgy recovery.
Investors flocked to the yen and safe-haven bonds following a slew of surveys on Wednesday that had shown German factory activity shrinking for the first time in 15 months, China's manufacturing sector barely growing and the United States slowing more than expected.
Confirmation of a case of Ebola in the United States joined a growing list of bearish news stories, with geo-political tensions in Ukraine, the Middle East and Hong Kong, and growth concerns around China and the euro zone sapping risk appetite.
All that pushed MSCI's 45-country world stock index <.MIWD00000PUS> to a five-month low as a fourth day of back-to-back falls left it down more than 5 percent in the last month.
There was little sign of the rout coming to end in Europe either. Britain's FTSE<.FTSE>, Germany's DAX<.GDAXI> and France's CAX<.FCHI> saw 0.3-0.6 percent falls while Italy <.FTMIB> and Portugal <.PSI20> were down more than 1 percent.
"The market is quite nervous," said Alvin Tan, a strategist at Societe Generale in London.
"What we are most concerned by is the risk backdrop. The S&P 500 appears to be in the process of breaking below the 100-day moving average and on top of that we see volatility picking up in not only equities but also currencies."
On top of all the geopolitical and growth concerns, markets are also struggling with the fact the Federal Reserve is about to end years of pumping billions of dollars of stimulus into the U.S. and global economy each month.

TRILLION EURO QUESTION
Markets in both China and Hong Kong had been closed for public holidays but sustained civil unrest in Hong Kong is also weighing on investor confidence, although the city's streets were calm for most of Thursday.
The risk-averse global mood had pushed 10-year U.S. Treasury yields
The dollar subsequently slipped back below 110 yen - a threshold breached for the first time since 2008 this week. It was last down 0.3 percent at 108.61 yen
The euro was a shade higher at $1.2638
Traders were focused on the European Central Bank meeting later in the session with the divergence in U.S. monetary policy from those of Europe and Japan now an established market theme.
ECB head Mario Draghi is set to give details at the bank's 1230 GMT (0830 EDT) post-meeting news conference of a new plan to buy asset-backed securities and covered bonds, hoping this will finally revive the euro zone economy.
It hopes the plans will add a trillion euros to its balance sheet, but poor demand for a new round of cheap loans last month is raising the pressure for it too be more aggressive.
"In the longer term people are still hoping for full-scale quantitative easing," said Robert Kuenzel, euro area economist at Daiwa Securities in London.
"But it is unlikely to come in the near future. I think the first line of defense is the TLTRO (cheap long-term loans to banks) and the covered bond and ABS purchase programs, but there is a risk that both of those components disappoint."
OIL PLUNGE
With the focus on damage limitation, gold added to small gains to rise 0.5 percent to $1,219.27
In commodities though, Brent crude oil
It has now lost 20 percent since June and sharp cuts in official selling prices from Saudi state producer Saudi Aramco on Wednesday gave the clearest sign yet that the world's largest exporter is trying to compete for crude market share.
"This is a structural change in the oil market, with Saudi Arabia explicitly stating that they are willing to compete on price," said Bjarne Schieldrop, chief commodities analyst at SEB in Oslo.
"I think Brent will fall below $88 before we see the bottom of the market."
