We tend to think of the sub-prime mortgage crisis as being largely concentrated in the United States. But there is a growing body of evidence that some parts of the UK are also heavily exposed to the risks of a sub-prime crisis. The Financial Times today carries an interactive map which highlights those towns and cities thought to be most at threat from a rise in housing repossessions. According to research from FitchRatings, mortgages made to subprime borrowers – home owners with a shaky credit history – account for 10 to 11 per cent of all private homes in six UK towns - namely Newport, Wales; Cleveland, Teesside; Wolverhampton; Cardiff; Manchester; and Galashiels, Scotland.
