January used to be a big month for Swiss bankers and their Russian clients. Many of the Moscow elite had made a tradition of coming to the Alps for the orthodox new year, skiing with their families, then catching up with their financial consiglieri. In St Moritz, one banker recalls how he would book blocks of rooms for his clients. He would entertain them with snow polo, rolling out the charm as they clinked champagne glasses and watched horses charge across a frozen lake. This year he couldn’t tempt a single one. For the best part of a decade, Russian money has coursed through the Swiss banking world. But, as Russia’s relationship with the west has soured in recent years, what was once a source of bumper new profits for Switzerland’s banks has become a financial and reputational risk. In the run-up to Russia’s invasion of Ukraine in February, many wealthy Russians were moving to better safeguard their money from political interference, putting assets in the names of relatives or shifting them to less closely scrutinised jurisdictions, such as Dubai. In its wake, a vast sanitisation operation is under way at Swiss banks, to try and wind down relationships with sanctioned individuals. Neutral Switzerland has matched all of the EU’s punitive financial measures against Russia. More than 1,100 of the Russian elite — including figures such as coal and fertiliser billionaire Andrey Melnichenko and banker Petr Aven, both regular visitors to Switzerland — have become financial personae non gratae in a country many had assumed would keep their fortunes safe. The biggest banks, such as the publicly listed trio of UBS, Credit Suisse and Julius Baer, have declared they will cease all new business in Russia. For critics, though these are weasel words. It is their existing Russian clients that are the problem. No one is expecting many new fortunes to be minted in Russia any time soon. “Switzerland has a terrible history when it comes to Russian dirty money,” says Bill Browder, a longstanding Kremlin critic and a former Russian investor. He is sceptical of how much commitment there is among Swiss bankers to enforcing sanctions. “The Swiss want to be seen as doing something, but they don’t actually want to do anything,” he says. The US Helsinki Commission, an independent US government agency that observes human rights and the rule of law in Europe, agrees. In a report issued in May, it labelled the alpine state and its banks “a leading enabler of Vladimir Putin and his cronies”. The Swiss government responded by calling US secretary of state Antony Blinken in protest. A spokesperson for the Swiss government said president Ignazio Cassis “rejected the [report] in the strongest possible terms”. Like their counterpart in St Moritz, Swiss bankers the FT interviewed for this story all declined to be identified. Many more refused to speak at all. Switzerland’s banking secrecy laws are draconian — talking about clients can earn a lengthy jail term — and talking about Russian clients is even more taboo. “When we were onboarding a lot of these clients [in the 2000s], the entire approach was just very different. And you can’t really say that publicly now,” says one former banker who handled eastern European and Russian clients until retiring two years ago. “These [Russians] were people who had earned so much money, so quickly, that they didn’t know what to do with it. They were basically ideal clients. As long as you had no questions about where that money had come from . . . and, basically, we didn’t.” Quite how much Russian money there is in Switzerland is open to question. In March, the industry body representing Switzerland’s banks, the Swiss Bankers Association (SBA), caused a stir when it released details of a study estimating there was SFr150bn-SFr200bn ($154bn-$205bn) held in accounts for Russian citizens. At the end of last year, the total cash held on behalf of customers by Switzerland’s banks was SFr7,879bn, more half of which was wealth from abroad, according to the SBA. The disclosure prompted hand-wringing in the Swiss media. Commentators, even at conservative outlets such as the newspaper Neue Zürcher Zeitung, asked whether Switzerland should do business with autocratic regimes anywhere in the world any more. But others in the country have defended its economic relationships with Russia. The outspoken finance director of the canton of Zug, an important low-tax centre, said in March it was not his job to “act like a detective” and make judgments on Russian assets. In April, he announced that Zug, home to 37,000 companies, had no sanctioned assets to report back to Bern. Nevertheless, by April, the State Secretariat for Economic Affairs (SECO) announced that it had frozen SFr9.7bn of Russian assets. Authorities have insisted that the amount is proportionate to the scale of asset freezes in other leading financial centres. But Bern has been forced to row back in some cases, and in May it announced it was unfreezing SFr3.4bn of funds. Switzerland cannot freeze funds “without sufficient grounds”, says Erwin Bollinger, a SECO official, who adds that the government has received data on sanctioned accounts at more than 70 of the country’s banks. Direct disclosure by the banks has been patchy. Credit Suisse chief executive Thomas Gottstein told a conference in March that about 4 per cent of assets in his bank’s core wealth management business were Russian — a proportion that would equate to roughly SFr33bn. Meanwhile, UBS, the world’s largest private wealth manager, has disclosed it has $22bn of assets of “Russian persons not entitled to residency in the European Economic Area or Switzerland”, leaving open the question of how much it holds overall. Some 16,500 Russians are permanently resident in Switzerland, and more Russians are accepted for Swiss citizenship than any other nationality, according to the State Secretariat for Migration. Julius Baer has made no direct disclosure of the size or wealth of its Russian client base, though it has said, somewhat elliptically, that the value of assets held by its Moscow-based subsidiary is some SFr400mn. Information from the dozens of other smaller Swiss private banks is even scantier. Even leading industry figures wonder what is being left unsaid. One executive, who for the past two decades has been a senior figure in the private banking world in Switzerland, says he has almost no doubt that the significance of many banks’ close working relationships with sanctioned individuals is being underplayed. “You don’t have dozens and dozens of people employed on your Russia desks if you are not making money in Russia,” he says. Moreover, he adds, many Russian clients have done their business through Swiss banks’ subsidiaries abroad, such as those in Monaco, London or Asia. It is not clear to him whether all these assets have been caught by the Swiss rules. Swiss banks have a legal obligation to record the ultimate beneficial owners of all assets they handle worldwide, but doing so accurately can be tricky in jurisdictions where it is easy for third parties to mask who the owners are. Switzerland’s banks have moved dramatically from the freewheeling approach of previous years, when there was “a run on Russia”, says Thomas Borer, a former leading Swiss diplomat turned consultant, who has worked with prominent Russian clients. He now supports Switzerland’s sanctions policy. “Being militarily neutral does not mean being economically indifferent,” he says. But he argues that Swiss banking culture is still very different from elsewhere in the west. Even the biggest banks, he says, were clinging to relationships with Russian clients as the Ukraine crisis unfolded. The Financial Times revealed that, as late as March, Credit Suisse was asking investors to destroy documents that might expose Russian oligarchs it had done business with to legal risks. One senior relationship manager at a Zurich-based bank agrees. Even as sanctions came in, he says, the dominant approach was to ask, “how can we make this work for the client?” rather than “how do we do this for the government?”. But he defends the approach, saying: “Doing everything you can for your client is a Swiss commitment to excellence. If I was a watchmaker I would want to make the best watches with many complications. And if I was a policeman, then maybe I would want to be the best at catching Russian criminals. But I’m a banker.” There is still legal ambiguity in Switzerland over whether sanctions apply to family members and friends of listed individuals. This has provided a loophole bankers have helped at-risk clients to actively exploit in recent years. Swiss banks have seen “billions” of assets transferred to the names of spouses and children of Russian clients, in a trend that accelerated in the run-up to the war, says one banker. One bank chief executive admitted recently to the FT that there were many “grey areas” in applying sanctions. Part of the problem, he said, was that bank legal departments were struggling to obtain clarity from Bern on which asset transfers were deemed to be evading sanctions and which were not. Many who have been in the industry for a long time decry the new rules they must follow around taking new clients and being certain of the source of their wealth. “Know your customer used to mean just that: do you know the person? Now it is supposed to mean: do you know every little thing about their financial and private life?” says one Geneva-based banker. Many Russians themselves knew the banks were no longer safe havens, particularly since 2018 when Swiss banks began making significant concessions to information sharing on client accounts with other governments. Swiss residency did not protect billionaire Viktor Vekselberg in 2018, for example, when he was targeted by US sanctions; both Credit Suisse and UBS moved to terminate loans with him. The SBA says its members adhere to the highest international standards. Chief executive Jörg Gasser, argues Swiss banks have “no interest in funds of dubious origin” and have rigorous procedures in place to rapidly screen for sanctioned assets. “Swiss banks have been — and still are — very careful and diligent when it comes to accepting client funds,” he says, adding it is important to recognise the huge amount of legitimate business done with Russian entrepreneurs who are not subject to sanctions. For Mark Pieth, emeritus professor of criminal law at the University of Basel and a specialist in white-collar crime, the real story of the past decade is how Switzerland’s lawyers, rather than its bankers, have become the facilitators of hidden foreign money. “Swiss bankers were extremely cosy with Russians in the past,” he says. “Alongside London, this country was the porch for Russians into the west . . . but now I wouldn’t say the problem is so much with the banks — it is all the other intermediaries.” Swiss law gives remarkable sweep to attorney-client privilege, says Pieth, meaning lawyers can refuse to disclose almost anything to the authorities about their clients. The Swiss Bar Association strongly rejects this. “Professional secrecy does not protect against criminal acts,” it says. “Lawyers know the law and know what to do.” One senior industry figure defends the banks’ position unapologetically. He says everybody now wants to know the origins of their luxury jackets. But 10 years ago nobody was asking where they were made, by whom and with what materials. In banking, as in fashion, things have changed, he says, but nobody is haranguing the fashion world in the same way they are criticising banks. Fashion companies, though, have moved with the times and opened up, whereas Switzerland’s banks, for all their insistence on change and compliance, still want to maintain as much of the secrecy surrounding their clients as possible — even at a time of international crisis.
