The US witnessed an unprecedented boom in mortgage debt and house prices in the early 2000s, which precipitated the crisis in 2007. This column documents a sudden, large and persistent fall in the spread of mortgage over Treasury rates in the summer of 2003. It argues that the emergence of this ‘conundrum’ marked a crucial turning point in the dynamics of the boom, with the resulting easier credit conditions in the subprime market in particular leading to the origination of mortgages that defaulted progressively more frequently down the road.

The Global Crisis narrative has suggested that an expansion of subprime credit was the reason for rising mortgage defaults, leading to the large-scale recession in 2007-09. Taking a closer look at the characteristics of subprime credit holders over the period, this column argues that the growth in mortgage defaults did not occur predominantly amongst subprime credit holders. Instead, it was real estate investors that played a critical role in the rise in mortgage debt, specifically among the middle and the top of the credit score distribution.

The global crisis is said to have originated in the US subprime mortgage market. This column argues that many of the most popular explanations that have emerged for the subprime crisis are, to a large extent, myths.
