Since the 2007–2008 financial crisis, there is a renewed interest in Hayek's core explanation of boom-and-bust cycles, which serves as an alternative explanation to that of the savings glut as launched by economist and former Federal Reserve Chair Ben Bernanke. Economists at the Bank for International Settlements, e.g. William R. White, emphasize the importance of Hayekian insights and the impact of monetary policies and credit growth as root causes of financial cycles. Andreas Hoffmann and Gunther Schnabl provide an international perspective and explain recurring financial cycles in the world economy as consequence of gradual interest rate cuts led by the central banks in the large advanced economies since the 1980s. Nicolas Cachanosky outlines the impact of American monetary policy on the production structure in Latin America.
