* Vienna stock market down 3.2 pct as Erste slumps
* Erste drags down other rival banks
* Broader European markets remain near multi-year highs
* FTSEurofirst 300 down 0.1 pct but near 6-1/2 year high
* U.S. market closed for public holiday
LONDON, July 4 A slump in the shares of Austrian bank Erste hit the Vienna stock exchange on Friday and halted a rally on the broader European equity market which had hit multi-year highs this week.
Erste dropped by 16 percent after the bank, which is the third-biggest lender in emerging Europe, warned that fresh hits from Romania and Hungary would drive it to a record 2014 loss.
Erste also dragged down the shares of Austrian rival Raiffeisen and weighed on Vienna's benchmark ATX index, which fell by 3.2 percent and underperformed other major European stock markets.
The STOXX Europe 600 Banking Index declined 1.2 percent, with other banks with links to eastern Europe also falling, such as Intesa and UniCredit which both weakened by 3.4 percent.
"Austria's banking system is particularly vulnerable due to its historic ties to eastern Europe," said HED Capital head Richard Edwards.
Edwards backed going "short" to bet on more losses for the Vienna's ATX, which is one of western Europe's smaller markets.
The ATX is down by nearly 4 percent since the start of 2014, underperforming a 5 percent rise on Germany's DAX - which has hit record highs - and a 6 percent advance on the pan-European FTSEurofirst 300 index.
The broader FTSEurofirst 300 index, which had risen for the last three days in a row to hover near 6-1/2 year highs, slipped by 0.1 percent to 1,396.80 points.
The euro zone's blue-chip Euro STOXX 50 index also retreated 0.4 percent to 3,276.98 points.
Trading activity was thin on Friday, with the U.S. stock market shut for a national holiday.
In spite of Erste's problems, many traders remained optimistic that European equities would rally towards the end of 2014, helped by a backdrop of strong U.S. jobs growth and economic stimulus measures from the European Central Bank (ECB).
They said that, for now, the falls at Erste and the Vienna market were not enough to hit larger banks and larger European equity indexes.
"The DAX and Euro STOXX are only marginally down, and I think that the broader market has a much stronger resistance nowadays to problems such as the ones we are seeing in Austria," said Berkeley Futures associate director Richard Griffiths.
