Great Recession
Overview
The Great Recession followed a twenty-year period that has been termed the "Great Moderation", during which recessions had been less frequent and less severe than in previous periods, and during which there been a great deal of successful financial innovation. Attitudes and habits of thought acquired during that period were to have a significant influence upon what was to come. Among other significant influences were the globalisation of financial markets, with the development of large international capital flows, often from the developing to the developed economies; the large-scale granting of credit to households in some of the major economies; and the creation there of house price booms, that have since been categorised as bubbles, but were not recognised as such at the time. It struck the major economies at a time when they were suffering from the impact of a supply shock in which a surge in commodity prices was causing households to reduce their spending, and as a result of which economic forecasters were expecting a mild downturn.
The trigger that set it off was the malfunction of a part of the United States housing market that resulted in the downgrading by the credit rating agencies of large numbers of internationally-held financial assets to create what came to be known as the subprime mortgage crisis. That crisis led to the discovery that the financial innovations that had been richly rewarding market traders in the financial markets, had also been threatening their collective survival. The crucial nature of that threat arose from the fact that the global economy had become dependent upon the services of a well-functioning international financial system.
The consensus view among economists was that the combination of monetary and fiscal expansion that was then undertaken by policy-makers was necessary to avoid a global catastrophe on the scale of the Great Depression of the 1930s - although there was a body of opinion at the time that considered a fiscal stimulus to be innecessary, ineffective and potentially damaging[1]. Despite that policy action, the discovery that they had been overvaluing their assets prompted negative reactions among both financial intermediaries and households.
