MOSCOW, March 22 (Reuters) - If Russian oligarchs still have money in Cyprus, where a lot of them base their businesses, they aren't letting on.
"You must be out of your mind!" snapped tycoon Igor Zyuzin, main owner of New York-listed coal-to-steel group Mechel , as he dismissed a suggestion this week that the financial meltdown in Cyprus posed a risk to his interests.
His response is typical across the oligarch class of major corporations and super-rich individuals, reflecting the assessment of officials and bankers on the Mediterranean island who say the bulk of the billions of euros of Russian money in Cyprus comes from smaller firms and middle-class savers.
The collapse of an economy 75 times smaller than its own may not have much impact in Russia, though the crisis has strained relations with the European Union, raised questions on Russian influence over Cypriot politicians and highlighted geopolitical competition for new offshore gas fields. But some would suffer.
As much as losses likely to be sustained on deposits held in Cypriot banks, pain for the Russian economy could come from a disruption in money flows between Russians which pass through the island - transfers that dwarf Cyprus's own national income.
Light regulation and taxes, cultural ties through Orthodox Christianity and the weather have long attracted the capital and savings of Russians - many keen to keep their wealth out of the sight of often predatory bureaucrats at home.
Yet precisely because investors can hide their wealth behind nominee structures - often held in the name of a local lawyer - it is difficult to say just how much Russian money is tied up on the Mediterranean island. Or how much has already left.
Where it is going is also unclear, though a possible rise in Russian deposits in fellow EU member Latvia, a former Soviet republic that hopes to enter the euro zone next year, has raised concerns of displacing instability northward.
Russians are believed to account for most of the 19 billion euros of non-EU, non-bank money held in Cypriot banks at the last count by the central bank in January, when total non-bank deposits were 70 billion, 60 percent of them classified as "domestic". Of 38 billion in deposits from banks, 13 billion came from outside the European Union.
But the ease with which Russians can establish residency and local corporations in Cyprus muddy the data. One senior financial source in Moscow said a total of 20 billion euros held by Russian firms in Cyprus was a "significant underestimate".
Cypriot central bank chief Panicos Demetriades was asked by Russia's Vedomosti newspaper this week how much Russians held on the island. He replied: "It depends how you count it."
Deposits formally identified as Russian totalled 4.9 billion euros, he said. Add the funds of shell companies believed to be linked to Russia and the figure rose to 10.2 billion euros. But many Russian and other analysts think the sums are much higher.
One Cyprus-based lawyer reckons that $2 billion in Russian money fled in the 10 days before banks were shut down this week while Nicosia argued over an EU bailout. Phones are ringing from Malta to the Isle of Man as that cash seeks a new safe haven.
Russian business leaders criticised the EU bailout plan, and the "haircut" it would impose on depositors. However, if Cyprus stands by its rejection, heavier losses could result.
"There will be a serious outflow of capital from Cyprus," said Vladimir Potanin, the chief executive of Norilsk Nickel , the world's largest nickel and palladium miner.
"It won't affect me or my company. But they have put Cyprus to the knife and what has happened is a disgrace."
Sources in the wealth management, advisory and banking industry in Nicosia say Russia depositors are typically smaller savers and entrepreneurs. Fiona Mullen, a British economist in Cyprus, said Russians she encounters tend to be buying 300,000-euro homes, not the palaces favoured by oligarchs in London.
"There is a lot of Russian business done through Cyprus," she said. "It's so difficult to do business in Russia, you've got to bribe so many people, that it's easier to do it through Limassol. It's kind of the back office for Russia."
A business adviser said of his Russian customers: "Clients would be well off, but not the private jet kind." Most did not use Cypriot banks to keep money but as a conduit for funds.
Cyprus charges foreigners no tax on dividend income and capital gains. A double taxation treaty with Russia provides attractive incentives for Russians to use Cypriot banks. Even on Thursday, with Nicosia in crisis, one adviser said he had had two new requests from abroad to set up Cyprus shell companies.
Given the risk of disruption to its financial flows, Russia in particularly concerned about any imposition of controls on capital movements; Cyprus has already drafted such legislation as a precaution in case the EU cuts off aid to its banks.
"If, in any way, capital flows are restricted that would have a significant impact on Russian businesses," said German Gref, chief executive of state-controlled Sberbank, Russia's largest bank.
"I hope the Cypriot government has the wisdom not to undertake such measures, because if they do all investors will leave the country. It would be a perfect case study in what not to do," the former economy minister told Rossiya 24 television.
Morgan Stanley has estimated that Cyprus, with a GDP of just $25 billion, is both the source and destination of 25 percent of Russian inward and outbound foreign direct investment - a result of Russians "round-tripping" their own cash via the island.
Cyprus was also the source of $203 billion in foreign loans to Russia between 2007 and 2011, equivalent to 24 percent of the total, Morgan Stanley economists wrote in a research report this week. Shrinking the Cypriot banking sector could force Russian firms to borrow more dearly elsewhere, they warned.
Russia's central bank gave a public assurance on Friday that it did not see Cyprus posing a meaningful danger for the Russian banking system: "I don't see any systemic or individual threat here," First Deputy Chairman Alexei Simanovsky told reporters.
State-controlled VTB has the largest presence on Cyprus, through its subsidiary Russian Commercial Bank. It has estimated potential losses in the tens of millions of euros in a worst-case scenario.
Russian banks have, meanwhile, shown no interest in a rescue deal through which they could acquire stakes in Cypriot banks, Finance Minister Anton Siluanov said on Friday after two days of talks with his Cypriot counterpart ended without a deal.
