Global stocks have rebounded today, buoyed by comments from European Central Bank President Mario Draghi that raised hopes of further monetary stimulus, following a turbulent few days that wiped trillions of euro off asset values.
All of the major euro zone markets gained at least 1.5%.
In Paris the CAC added 1.97%, while the DAX in Frankfurt (+2.94%) and the ISEQ in Dublin (+1.55%) also gained.
In London the FTSE rose 1.77% - up from its lowest rate in more than three years yesterday.
US stocks were up in late morning trading, led by gains in telecommunications, energy and consumer discretionary shares, but trading was again choppy in most asset classes.
The euro fell to a two-week low against the dollar after Mr Draghi hinted of additional stimulus measures as early as March as economic risks had grown.
He cited concerns over China and emerging markets, volatility in financial and commodity markets and geopolitical risks, and said the tumult would prompt a March review of monetary policy.
The euro fell below $1.08 for the first time in two weeks during his speech.
Oil rebounded after falling to a more-than-12-year low the previous day. US crude futures were up nearly 1% at $28.60 per barrel.
Yesterday US crude futures fell to their lowest since September 2003.
Crude oil prices, which have dropped more than 25% since the start of the year, have been a key driver of a recent cross-asset rout.
"The underlying focus is still on oil because people are looking at the transmission mechanism to the real economy of lower oil prices," said Gennadiy Goldberg, interest rate strategist, at TD Securities in New York.
"Lower oil prices are maybe great for the consumer, but not unilaterally good for the US economy."
US Treasury debt yields edged lower in choppy trading, weighed by concerns over volatility in oil and global stock markets.
In the equity market, MSCI's all-country world stock index rose 0.5%. Europe's pan-regional FTSEurofirst 300 index jumped 1.9%.
The Dow Jones industrial average was up 131.35points, or 0.83%, to 15,898.09, the S&P 500 gained 14.29 points, or 0.77%, to 1,873.62 and the Nasdaq Composite added 28.56 points, or 0.64%, to 4,500.25.
A 3% slump in Chinese stocks gave Asia another bruising.
MSCI's 23-country emerging market index notched a 6-1/2 year low and Russia's rouble tanked almost 5% at one point as it set a record low against the dollar for a second day running.
