* Emerging assets sink, underperform global peers
* Turkish lira recovers, South African rand falls
* Weak commodities snap Russian winning streak
By Sebastian Tong
LONDON, Oct 27 (Reuters) - A dollar recovery triggered an emerging-markets rout on Tuesday as investors grew concerned about the scaling back of economic stimulus while an oil-price retreat snapped the Russian rouble's six-day winning streak against its currency basket.
Turkey's lira recovered after Monday's selloff, emboldened by brightening prospects of a ratings upgrade, and South Africa's rand widened losses after the country's finance minister said the government was concerned about its strength.
Suffering its biggest one-day drop in over two months, the benchmark emerging equities index <.MSCIEF> underperformed its global peer <.MIWD00000PUS> to slip 1.4 percent by 1210 GMT to its lowest level in nearly two weeks.
Emerging sovereign debt spreads <11EMJ> widened 3 basis points to trade at 306 bps over U.S. Treasuries.
"The mood is a little nervous because of the dollar strength. Emerging markets benefit from a weaker dollar as no one wants to hold dollar cash. But when the dollar rises, the (emerging markets) rally corrects," said Kieran Curtis, an emerging debt fund manager at Aviva Investors.
The dollar was flat against a basket of currencies <.DXY> after steep gains in the previous session. [
]Sentiment was also weighed by India's move to tighten credit to its commercial property sector, which came along with warnings about the threat of asset price bubbles. [
]Coming after the raising of interest rates in Israel and Australia, the move heightened investor jitters over the eventual withdrawal of stimulus measures that have underpinned the global economic recovery so far.
Chinese <
> and Indian < > shares tumbled over two percent, amplifying the selldown seen earlier on U.S. bourses."There's generally a bit of defensiveness going on...Some of the commodities have come off a bit and that has been a catalyst (for emerging-market) losses," said Julian Mayo, investment director at Charlemagne Capital.
Weaker commodity prices knocked resource-focused South Africa <.JTOPI> and Russia <
>, whose shares slipped from recent 13-month highs to chalk up the day's heaviest losses.After setting fresh 2009 highs in successive sessions, the rouble proved to be one of the day's biggest casualties, falling over 0.5 percent versus its dollar-euro basket as oil slipped below $80 a barrel <CLc1>.
Russia's central bank had been seen intervening on Monday to slow the rouble's ascent. [

LIRA RECOVERS, RAND FALLS
Czech stocks <
> fell over one percent to their lowest in more than two weeks while Romanian shares < > fell over two percent in their biggest drop in three weeks.Emerging currencies were mostly weaker though the Turkish lira pared previous day losses against the dollar <TRY=> after falling over one percent to three week lows on Monday.
Fitch placed Turkey on its rating watch positive, saying that its ongoing review of the country has a "strong likelihood of leading to an upgrade." [
]South Africa's rand fell against the dollar <ZAR=> after its finance minister said the government is concerned about its strength and would have liked to intervene more assertively in the market. [
]The rand has gained 25 percent versus the greenback so far this year despite concern about the government's widening budget shortfall.
"The fiscal issue, plus the uncertainties surrounding the government's stance regarding the currency's strength may be triggering factors for a correction of the ZAR's overvaluation," SocGen said in a client note.
Meanwhile, Romania's leu remained flat against the euro <EURRON=>, with investors sidelined by fears of central bank intervention to shore up the currency.
On Monday, Romania rejected all bids at a one-year treasury bill sale due to high premiums demanded by investors.
The collapse of its government earlier this month has raised doubts over the country's ability to enforce reforms under its International Monetary Fund package. [
