Immigrant workers in Russia know their families will benefit when they send some of their hard earned cash back home. They will also be aware that, via the fees it charges, the money transfer facilitator will take a slice. But they would be less likely to envisage that their actions might also help to line the pockets of a private equity investor.

In late November, that scenario took a step closer to reality when London-listed investment vehicle Aurora Russia agreed to acquire a 26 percent stake in Unistream Bank in a deal expected to complete in the first quarter of 2007. Unistream accounted for a quarter of all money transfers make to and from Russia in the first half of 2006. While it has operations around the world, the firm's most lucrative business comes from the 15 million Russian immigrant workers from the CIS countries (including former Soviet republics such as Georiga and the Ukraine).

Statistics from the Russian Central Bank make clear that this is a fast growing area of business. Last year, the Bank estimates that between $3-6 billion was sent home by Russian immigrant workers, while, from 2003 to 2005, transfers in and out of the country grew at an annual compound growth rate of 56 percent.

Aurora director John McRoberts says that many of Unistream's customers at present are construction site workers in Moscow. However, the client base is expected to diversify. In a statement announcing the deal, Aurora said: “As more and more businesses in Russia embark on a regional development strategy, more jobs will be created in the regional cities of Russia, creating attractive opportunities for additional immigrants”.

Unistream is majority-owned by UniAstrum Bank, a top ten Russian bank by number of branches, which has retained a 74 percent stake. Aurora, which is investing a £75 million fund, has been brought in to help guide the company towards a planned IPO in two to three years' time. At which point, it may become evident just how lucrative money transfers can be – and not just for those involved in the initial transaction.
