Although the World Bank collaborates with international agencies that work with external debt and debt-related statistics (the Bank for International Settlements (BIS), the International Monetary Fund (IMF), the Organisation for Economic Co-operation and Development (OECD) and others), the World Bank has the international mandate to collect external debt data, and we maintain comprehensive external debt information.
The World Bank has been collecting statistics on the debt of its borrowing countries since 1951, through the Debtor Reporting System. Published for many years as World Debt Tables (see, for example, the 1982 edition here) and then as Global Development Finance (initially as Volume 2), the 2013 dataset - which contains data for 2011 - was published in a renamed publication as International Debt Statistics, with expanded coverage of Quarterly External Debt Statistics and Public Sector Debt.
Last year we reviewed our dissemination strategy for World Development Indicators (WDI), and made some improvements to improve the quality and accessibility of the statistical indicators, tables and analyses. This year we’ve looked at debt statistics, and are planning some changes here as well; while the 2014 dataset - which contains data for 2012 - has been released in mid-December as usual, we’ll be releasing the redesigned data products in mid-February.
