Richard L'Estrange describes the characteristics of the economic crisis and how journalists, economists and commentators have clamoured to define them:
The origins of economic downturns used to be at least somewhat comprehensible. But even a keen reader of the financial pages must have found their eyes glazing over when the conversation turned to collateralised debt obligations and asset-backed securities, alpha-seeking hedge funds and sub-prime mortgages. The two defining characteristics of this ‘crisis' have been the rapid speed at which the turmoil has manifested itself, and the unique causes that underpin it.
