In 1995, facing severe fiscal deficit and in desperate need of funds for the 1996 presidential elections, the government of Boris Yeltsin adopted a "loans-for-shares" scheme proposed by banker Vladimir Potanin and endorsed by Chubais, then a deputy prime minister, whereby some of the largest state industrial assets (including state-owned shares in Norilsk Nickel, Yukos, Lukoil, Sibneft, Surgutneftegas, Novolipetsk Steel, and Mechel) were leased through auctions for money lent by commercial banks to the government. The auctions were rigged and lacked competition, being largely controlled by favored insiders with political connections or used for the benefit of the commercial banks themselves. As neither the loans nor the leased enterprises were returned in time, this effectively became a form of selling, or privatizing, state assets at very low prices.
