* Ukraine in focus as IMF goes in
* Hungarian forint slumps as banks cut forex lending
* Iceland central bank cuts rates, sees severe economic contraction

LONDON, Oct 15 (Reuters) - Stock markets across emerging markets fell on Wednesday, with economic contagion from the global financial crisis spreading to Hungary and Ukraine with other central and eastern European markets in focus.
With troubled Iceland -- the country most damaged by the increasingly global credit crunch -- still scrambling to secure foreign currency and with the Icelandic crown still effectively untraded internationally, fears of further crises are growing.
Ukraine's government confirmed on Wednesday it had called in the International Monetary Fund (IMF), while the Hungarian forint <EURHUF=> fell more than 5 percent at one stage against the euro as local banks ceased lending in foreign currency.
Russia once again closed its RTS stock market <
> for an hour -- an increasingly regular occurrence -- after it fell 6.89 percent, exceeding technical limits.Russian markets have been hugely volatile in recent weeks, seeing mass capital flight as the worsening in the credit crunch that followed the bankruptcy of Lehman Brothers came hard on the heels of investor nerves over war with Georgia.
Overall benchmark emerging equities <.MSCIEF> fell 3.54 percent by 1000 GMT, after rallying earlier in the week on hopes that Western governments' purchases of stakes in their own troubled banks might help reboot the paralysed financial sector.
"In emerging markets, we are taking guidance from equity markets globally -- which are obviously not doing well," said TD Securities chief strategist Beat Siegenthaler.
Sovereign debt spreads were steady at 544 basis points over U.S. Treasuries <11EMJ> after narrowing sharply on Tuesday.
After the collapse of Iceland's massively indebted banking sector, which dragged down the crown currency and the wider economy, analysts are increasingly nervous about more exposed eastern and central European economies.
WATCHING FOR TROUBLE
Iceland's central bank warned on Wednesday the next phase of its banking crisis would be difficult, and forecast severe economic contraction. It cut interest rates by 3.5 percentage points to 12 percent. [
]It also said it was setting up a temporary daily auction system to allow for international currency deals. [
].Ukraine's economy said an IMF team will arrive on Wednesday to examine its financial situation. [
]Ukraine has suffered widespread fears over the stability of its banking system, is running a large current account deficit and has seen increasing investor worries over political instability after the ruling coalition collapsed and the Georgia war drew attention to increasingly shaky relations with Russia.
The cost of insuring Ukrainian debt in the credit default swaps market increased sharply by some 200 basis points to 1500-1700 bps, meaning it would cost between $1.5 and $1.7 million a year over five years to ensure $10 million of debt -- practically pricing in default.
Hungarian CDS were 30 basis points wider at 350-375.
"Hungary and Ukraine are under massive pressure," said one trader. "It's hard to see any end in sight for these two countries at the moment."
A second bank in Hungary imposed limits on foreign currency loans on Wednesday, saying it wanted to protect clients from currency swings, following one on Monday. [
]Depreciation across emerging market currencies has made it more difficult for local borrowers to repay foreign loans.
Normally, such loans would then be exchanged into local currency, helping support the forint. Facing their removal from the marketplace, the forint fell.
Other central and eastern European currencies were also broadly lower, with the Czech crown <EURCZK=> down 0.63 percent and the Polish zloty <EURPLN=> losing 1.42 percent.
"These headlines out of Hungary about banks stopping lending in foreign currency has created quite a lot of volatility," said Siegenthaler, seeing Romania and Poland as next most vulnerable through having a large volume of foreign exchange loans.
Other analysts pointed to the Baltic states as potentially next in line for serious trouble. (Additional reporting by Carolyn Cohn, editing by Swaha Pattanaik)
