LONDON, Aug 18 (Reuters) - Stocks fell on Tuesday, with European markets buckling under heavy selling pressure carried over from Asia after Chinese shares slumped 6 percent and emerging market currencies and oil prices remained anchored at historic lows.

"European equity markets are taking their cues from China, and traders' suspicion is that the second largest economy in the world is heading for a hard landing," said David Madden, market commentator at IG in London.
"The more the Chinese government intervenes, the more traders want to dump stock and head for the exit. The mood in London is that the party is over in China."

The worries over China came amid a relatively calm day in yuan trading after Beijing fixed the currency's exchange rate at a marginally higher level for the third straight session.
China's central bank on Tuesday set the yuan's midpoint CNY=SAEC near Monday's closing price at 6.3966 per dollar. But the yuan fell slightly in the spot market to 6.4090 CNY=CFXS , raising some concerns that it could fall further.

"The weakness of sentiment in emerging market FX is striking," Societe Generale (PARIS:SOGN) currency strategists in a note to clients on Tuesday.
