The Credit Crunch of 2007-2008: A Discussion of the Background, Market Reactions, and Policy Responses
This article discusses the events surrounding the 2007-08 credit crunch. It highlights the period of exceptional macrostability, the global savings glut, and financial innovation in mortgage-backed securities as the precursors to the crisis. The credit crunch itself occurred when house prices fell and subprime mortgage defaults increased. These events caused investors to reappraise the risks of high-yielding securities, bank failures, and sharp increases in the spreads on funds in interbank markets. The author evaluates the actions of the authorities that provided liquidity to the markets and failing banks and indicates areas where improvements could be made. Similarly, they examine the regulation and supervision during this time and argues the need for changes to avoid future crises.
