European shares and oil prices held steady at multi-year lows on Thursday after a torrid two days that has wiped trillions of dollars off global markets.

A 3-per cent slump in Chinese stocks had given Asia another bruising, so there was relief as early 0.2-0.4 per cent gains for London's FTSE, Germany's DAX and France's CAC 40 pulled markets out of their nosedive.

The FTSEurofirst 300 hit its lowest since October 2014 on Wednesday and the MSCI all-world country index was at its June 2013 low.

Oil prices, down more than 25 percent this year, have been one of the main drivers of the cross-asset rout, were also steadier at $27.60 for Brent and $28.15 for WTI.

The European Central Bank (ECB) meets on Thursday and is expected keep already record low interest rates on hold. Traders will be watching closely to see what impact the latest market turmoil is having on the bank's decision makers.

"Europe is holding up a bit better which is welcome considering Asia equities continued to trade lower," Societe Generale strategist, Alvin Tan, said.

"For one thing, oil is not exactly rallying but at least it is holding on, and we have the ECB meeting today which is a big event, so I think people are just being a bit more restrained."

With nerves still fragile and risk appetite low, the strain continued to show on euro zone periphery bonds. Portuguese 10-year yields rose 6 basis points (bps) to 3 per cent, pulling the gap with German equivalents to its widest since October 2014.

In Italy, with yields up 3 bps at 1.69 per cent, the gap was the widest since August last year.

In emerging markets, the tensions were even more intense. Russia's rouble tanked more than 3 per cent as it set a record low against the dollar for a second day running.

China stocks also ended down 3 per cent after a volatile session there. That in turn sent MSCI's broadest index of Asia-Pacific shares outside Japan to a new 4-year low.

Japan's Nikkei average ended down 2.4 per cent, adding to its 3.7 per cent plunge in the previous session.

Shanghai-based investor director at Nanhai Fund Management Co, David Dai, said fears of a prolonged bear market were, nevertheless, overdone.

"With stocks having fallen so much, much of the risk has been priced in and another free-fall is quite unlikely, although the chance of a sustainable rebound is slim," he said.

In the currency markets, the dollar index, which tracks the US unit against a basket of six counterparts, was down about 0.1 per cent at 99.025.

The greenback shed about 0.1 per cent to 116.75 yen after falling to 115.97 on Wednesday, undermined by US data . Ahead of the ECB meeting, the euro was buying just over $1.09. Before the last one in December, it had been just above $1.05.

"Risk aversion related to global issues may result in periods of support for the euro," Credit Suisse currency analysts wrote.

"Falling oil, however, raises risks that ECB may ease again," they said
