Currently, gas trade in Russia is regulated by the Federal Tariffs Service, or FTS. While Gazprom has to respect FTS' prices within a 3 percent margin, independents can sell below the minimum tariffs, allowing them to gain market share. In an oversupplied gas market, the reintroduction of spot trading, expected this fall, could boost even more the expansion of the gas independents at the expense of Gazprom.
