Achievements of Elvira Nabiullina as central bank chief in Russia since 2013 are the reducing of US dollar reserves from 40% to 11%of $600 billion in Russian reserves shifting to hold most of its reserves in euros, gold or renminbi Chinese currency. She also implemented the alternative to SWIFT the global bank messaging system, and changed the payments infrastructure to process credit card transactions in the country so departure of Visa and Mastercard had minimal effect.
In this way this highly respected banker has protected Russia's economy from western sanctions, says NYT. She is trusted by president Putin and was adviser to Putin in 2012, minister of economic development before that when Putin was prime minister. When Russia suffered an economic crisis in 2014 as oil prices fell sharply and Saudis increased oil production, the ruble fell. Nabiullina increased rates to 17%, and the economy shrank till it stabilized with inflation down to 4% by 2017.
