Elvira Nabiullina, head of Russia's central bank, is a think tank economist who was Economy minister before becoming chief economic advisor to Russian president Putin in 2012. She is one of the liberal economists in Russia who see the years of economic growth following ruble devaluation in 1998 as an example of how devaluation can actually help the economy. The devaluation lowers costs for manufacturing and agriculture, and is seen by some economists as having done more than oil price increases to help the Russian economy grow during president Putin's first term from 1999 to 2004. Nabiullina's position to support a free float after the sharp decline in the value of the ruble following the plunge in oil prices, is based on the need she sees to use the crisis to reduce Russian overdependence on imports. This policy had other advantages by reducing the need to tap Russia's foreign currency reserves to defend the ruble. Russia's gold and foreign currency reserves are at $385 billion. In Jan 2015 the central bank cut interest rates. A policy of increasing rates would trigger a sharper recesssion. Russia faces a unique situation in that the oil price decline and the decline in the value of the ruble occurred at about the same time of about 50%, so that the budget continues to be balanced. The number of rubles coming in from oil exports remains the same after the crisis. Nabiullina told Russia 24 television- "We have to live in a different zone, Russians should orient ourselves more toward our own sources of financing projects, and to give a chance to import substitution."...
