This paper introduces a new broad-based index of financial development, which summarizes the depth, access, and efficiency of financial institutions and markets across 183 countries from 1980 to 2013. The index is constructed using nine sub-indices, which are aggregated into an overall financial development index. The data sources include the World Bank FinStats, IMF Financial Access Survey, Dealogic corporate debt database, and BIS debt securities database. The index is designed to capture the multidimensional nature of financial development, including financial institutions' depth, access, and efficiency, as well as financial markets' depth, access, and efficiency. The paper discusses the methodology used to construct the index, including data normalization, treatment of missing data, and aggregation. It also presents the results of the index, including a world map of financial development in 2013, and compares the index with traditional measures of financial development. The paper highlights the limitations of the index, including the lack of data on certain aspects of financial development, such as shadow banks and financial payments. The index is an improvement over traditional measures of financial development, as it incorporates a broader range of financial development features for a wider array of financial agents. The paper concludes that financial system development needs to be assessed in a comprehensive way, taking into account not only the size and complexity of financial institutions and markets but also their accessibility and efficiency.This paper introduces a new broad-based index of financial development, which summarizes the depth, access, and efficiency of financial institutions and markets across 183 countries from 1980 to 2013.
