Simeon Dyankov

Simeon Dyankov (Bulgarian: Симеон Дянков, also Djankov; born July 13, 1970) is a Bulgarian economist. From 2009 to 2013, he was the deputy prime minister and minister of finance of Bulgaria in the government of Boyko Borisov. He has been a vocal supporter of Bulgaria's entry into the Eurozone. Before his cabinet appointment, he was the chief economist of the finance and private sector vice-presidency of the World Bank.

He was an associate editor of the Journal of Comparative Economics from 2004 to 2009. Dyankov was a chairman of the board of the European Bank for Reconstruction and Development. From 2013 to 2015, he was appointed rector of the New Economic School in Moscow. Since November 2015, Dyankov has been co-director for policy of the Financial Markets Group at the London School of Economics.

At the World Bank, Dyankov was director for development policy and senior director in the office of the chief economist. He led projects on the post-communist economic transition in Georgia (country), Moldova and Ukraine. Dyankov was also involved in the publication of Women Business and the Law, World Development Reports and Doing Business reports. The Doing Business reports were discontinued after an audit documented that Dyankov, along with then World Bank CEO Georgieva, pressured staff to make data for China and Saudi Arabia look better.

Since April 2020, Dyankov has been policy director at the Financial Markets Group at the London School of Economics. He has also been a senior fellow at the Peterson Institute for International Economics. He has written widely on the economic impact of the 2022 Russian invasion of Ukraine. This invasion has resulted in significant loss of human capital, destruction of agricultural trading infrastructure, huge damages to productive capacity, including through the loss of electricity, and a reduction in private consumption of more than a third relative to pre-war levels. The all-out aggression requires an all-out response by the European Union to win the war.
