The US economy faces a 40 to 45 per cent risk of recession induced by the housing market downturn, the chief executive of Freddie Mac warned on Thursday as data showed sales of new homes hit a seven-year low in August.

Richard Syron, chief executive of the government-sponsored mortgage company, said the credit squeeze had left some parts of the US housing market “literally frozen”. This was a “substantial depressive to the overall economy”. He forecast the Federal Reserve would make another “material” cut in interest rates.
