The October 2017 Global Financial Stability Report (GFSR) finds that the global financial system continues to strengthen in response to extraordinary policy support, regulatory enhancements, and the cyclical upturn in growth. Global bank balance sheets are stronger because of improved capital and liquidity buffers, amid tighter regulation and heightened market scrutiny. However, some banks are still grappling with legacy issues and business model challenges, where progress has been uneven. The environment of continuing monetary accommodation—necessary to support activity and boost inflation—may lead to a continued search for yield where there is too much money chasing too few yielding assets, pushing investors beyond their traditional habitats. As the search for yield intensifies, vulnerabilities are shifting to the nonbank sector and market risks are rising. This may lead to a further compression of risk compensation in markets and higher leverage in the nonfinancial sector. These challenges must be managed carefully to avoid putting growth at risk. Policymakers at both the national and global level will have to strengthen the financial and macroeconomic policy mix. The October 2017 GFSR also includes a chapter that examines the short- and medium-term implications for economic growth and financial stability of the past decades’ rise in household debt. It documents large differences in household debt-to-GDP ratios across countries but a common increasing trajectory that was moderated but not reversed by the global financial crisis. Another chapter develops a new macroeconomic measure of financial stability by linking financial conditions to the probability distribution of future GDP growth and applies it to a set of 21 major advanced and emerging market economies. The chapter shows that changes in financial conditions shift the whole distribution of future GDP growth.
