We have developed a set of such sector-specific metrics that are comparable across countries and constructed a preliminary “debt and deleveraging heat map” (Exhibit 3). It color codes each sector according to its likelihood of deleveraging: red is high; yellow is moderate; green is low. The map shows that ten sectors in five economies have the highest likelihood of deleveraging. These are the household sectors in five mature economies (the United Kingdom, the United States, Spain, and to a lesser extent Canada and South Korea), the commercial real estate sectors in three of these economies (the United Kingdom, the United States, and Spain), and the corporate sector and parts of the financial sector in Spain. But the publicly available data are imperfect, inconsistent, and not sufficiently granular for robust
policy making. A natural role for the institutions charged with maintaining national and international financial stability (such as the International Monetary Fund or Financial Stability Board) would be to develop and maintain this type of monitoring system and take it to the next level of detail.
