This IMF Working Paper introduces a new broad-based index of financial development, developed by Katsiaryna Svirydzenka. The index aims to capture the multidimensional nature of financial development, which includes depth, access, and efficiency of financial institutions and markets. The paper constructs nine sub-indices to measure these dimensions and aggregates them into an overall index of financial development. The methodology involves data normalization, aggregation, and the use of principal component analysis for weighting. The index covers 183 countries from 1980 to 2013 and is designed to provide a comprehensive tool for researchers and policymakers. The paper discusses the limitations and caveats of the index, emphasizing that it captures only partial aspects of financial development and does not include underlying drivers or outcomes.This IMF Working Paper introduces a new broad-based index of financial development, developed by Katsiaryna Svirydzenka.
