* Emerging assets rebound spurred by German survey
* South Africa's rand up as much as 2 pct on commodities
* Turkish markets up ahead of expected rate cut

LONDON, Aug 18 (Reuters) - Emerging markets steadied on Tuesday, a day after suffering their biggest one-day fall in 4-1/2 months, as brightening German economic sentiment offset overnight losses on Wall Street and volatile Chinese markets.
South Africa's rand rose as much as 2 percent against the dollar <ZAR=>, clawing back recent losses on a recovery in commodity prices, while Turkish assets rose ahead of an expected interest rate cut later in the day.
Emerging shares <.MSCIEF>, which fell over 3.8 percent in the previous session to hit their lowest level in nearly four weeks, firmed 0.4 percent by 1030 GMT.
Emerging sovereign debt spreads tightened 4 basis points to trade at 380 bps over U.S. Treasuries.
A survey by Germany's ZEW research institute showed analyst and investor sentiment in Europe's largest economy improving more than expected, spurring a rebound after Monday's sell-off saw U.S. shares suffer their worst loss in seven weeks. [
]A late rebound in Chinese stocks also helped soothe investor fears that a rally which has driven the country's shares up 90 percent this year may have outpaced its economic recovery.
"The ZEW survey out of Germany was remarkably positive across the board, not just in one or two elements or in the headline number," said Zsolt Papp, chief economist emerging Europe at KBC.
"Investors are not quite ready to take the market lower. No one's really convinced this is the starting point of a big rally but everyone is afraid of taking this market really lower."
Romanian shares <
> rose 1 percent after falling nearly 5 percent on Monday, their biggest one-day loss in three months.A rebound in commodity prices supported modest gains in Russian <
> and South African shares <.JTOPI>, which both rose just under 1 percent after falling 5 percent and 3 percent respectively in the previous session.
SOUTH AFRICA
Stronger commodity prices nudged the rouble 1 percent higher against its dollar-euro basket <RUS=MCX>.
The rand, which retreated nearly 1 percent in the previous session, recovered to rise as much as 2 percent versus the greenback before paring gains.
Second-quarter gross domestic product figures from South Africa showed a smaller-than-expected contraction but otherwise provided little support for the currency. [
]"It provides confirmation that South Africa's economy still lags that of the rest of the world," said Razia Khan, regional head of research Africa at Standard Chartered Bank.
"This is likely to give rise to more thinking on how to make the fiscal stimulus more effective."
Along with its equity market, Turkey's lira currency <TRY=> and its bonds <TRGLB30=RR> were higher ahead of a central bank meeting later in the day widely expected to yield a 50 bps cut.
"We expect a mildly positive reaction on the bond market after the decision but we do not foresee substantial declines in yields in the coming weeks, particularly given worsened risk appetite," BNP Paribas said in a client note.
"On the currency side, the 1.516-1.520 resistance area on dollar/lira remains intact while 1.49 should constitute a support level."
Meanwhile, the cost of insuring Lithuanian sovereign debt eased a day after Standard & Poor's (S&P) removed the Baltic economy from its CreditWatch negative position, which had suggested an imminent ratings downgrade. [
]. S&P affirmed Lithuania's 'BBB' credit rating, citing the government's commitment to address worsening public finances.Five-year credit default swaps to protect against the default or restructuring of Lithuanian sovereign debt was quoted at 372.5 bps, down from 380.7 bps, according to CMA DataVision.
