LONDON, Aug 10 (Reuters) - Emerging stocks fell 1 percent to an eight-day low on Tuesday, as caution about Federal Reserve policy dented risky assets, but the Polish zloty hit fresh three-month highs, prompting a central bank warning.
Emerging assets have had a good run in the last few weeks, boosted by the easing of the euro zone sovereign debt crisis and a refocus on strong domestic fundamentals. However, speculation has been growing that the U.S. Federal Reserve will at its meeting later on Tuesday signal a need for more stimulus to support U.S. growth or possibly restart asset purchases, known as quantitative easing.
Chinese stocks <

"Everywhere is down today, reflecting a general pullback in risk appetite which is hitting emerging markets," said Neil Shearing, senior emerging markets economist at Capital Economics.The MSCI emerging equities index <.MSCIEF> dropped 1 percent to an eight-day low and the Thomson Reuters Emerging Europe index <.TRXFLDEEPU> fell 0.77 percent.
Emerging sovereign debt spreads tightened by 2 basis points to 261 bps over U.S. Treasuries <11EMJ>, however, and are trading around their narrowest in three months in the absence of new supply over the quiet August period.
The South African rand eased from 2-1/2 year highs against the dollar <ZAR=> set on Monday, as public sector unions threatened a prolonged strike. [
] As the zloty hit a fresh three-month high against the euro close to 3.95 <EURPLN=>, Polish central bank governor Marek Belka said he hoped the currency's appreciation trend would not be too strong. [ ]Poland's currency has been volatile in recent months and the central bank has intervened both to buy and sell zloty.
"Poland is likely to hike interest rates as soon as Q4 this year," said analysts at ING in a client note.
"Should this expectation build, euro/zloty may well re-test its April (3.80) mark."
Debt insurance costs climbed slightly in emerging Europe. Ukraine's five-year CDS rose to 505.4 bps, according to CMA DataVision, after dipping to a four-month low below 500 bps on Monday, when the central bank cut its key discount rate by 75 basis points to 7.75 percent, the third cut this year.
Analysts see inflationary pressures in Ukraine.
"Inflation will go up," said Shearing. "We will see the effect from the gas price rise and there is the food angle too."
Ukraine raised domestic gas prices this month and traders say the drought-hit country is holding up wheat exports. [
]Russian 5-year CDS also ticked up as oil prices weakened and investors focused on the smog in Moscow and the drought, which prompted Russia last week to ban grain exports.
"The drought will have an impact on the Russian economy and inflation and food prices in particular, and I wouldn't want to underplay that. But comparisons with the food price shocks of 2007-2008 are misplaced," said Shearing.
"Part of the problem back then was that the Russian economy was operating above potential but now it is operating below potential and it's difficult to see the food price inflation leading to wage inflation and feeding through massively into core inflation."
