[ by Melanie Gretchen ] Goldman Sachs' chief equity trader in Moscow called it quits and was leaving to return the the United States - specifically, New Jersey.  But instead of remaining in the industry and joining one of the Jersey-based market makers - like Knight Capital - he plans to finish building a commercial Russian sauna. Born in New York to parents who emigrated from the former Soviet Union, Peter Kizenko had been working in Moscow for the past 18 years.  The driving forces for his decision to leave Moscow and the securities industry are the growth of electronic trading and the declining compensation in the industry.  The advent of increased regulation, that has forced banks - including Goldman Sachs - to cut back their proprietary trading activities and cut back on pay, has reached firm traders in Russia. Planning a March Opening for the 'Banya'. The banya tradition dates to the 11th century in Russia. A wooden log shed is heated by an electric or wood-burning stove to more than 80 degrees Celsius (176 degrees Fahrenheit).  Copious amounts of water are poured on the heat source to bring the humidity to about the same level.  A visit to a banya begins with several rotations in and out of the steam room to allow the body to warm up. Naked bathers typically beat one another with birch or pine branches before plunging into cold water or rolling in snow to cool down. Facing Stiff Competition. There are about 5 to 7 banyas already in the New York area, according to Kizenko, who considered opening one in London until he saw how expensive the rents are.  “There are a few in Brooklyn and Manhattan, but the aesthetics are not up to scratch,” he added.  “We are going for a mixture of the contemporary and the classical of Sanduny in Moscow.” Kizenko had his banya, called Bear and Birch, made in Russia and shipped to the U.S. Built in the 19th century for nobles, the Sanduny baths near the Kremlin are Moscow’s fanciest. The poet Alexander Pushkin and the writer Leo Tolstoy are said to have bathed there. More recent visitors include the actors John Travolta, Dolph Lundgren, and the billionaire Roman Abramovich. C-I wishes ex-Goldman Comrade Kizenko the best of luck. For further details, go to [Businessweek, 2/1/12].
