We examine whether the global financial crisis has prompted banks to tighten lending standards. By analyzing nearly 31,000 syndicated loans to private borrowers in 65 countries over the period 2005-2009, we find that banks not only cut lending during a crisis but also increase their screening and monitoring. Lending standards are tightened in particular for uncollateralized loans, loans to first-time borrowers, and financial-sector borrowers in developed countries. While in developed countries screening and monitoring increases less for loans to rated borrowers and for loans structured by well-known arrangers, we show that the attenuating impact of credit ratings and arranger reputation does not extend to emerging markets.
