With mainstream news like this, who needs tinfoil?

BANKS in the UK have been ordered by financial regulators to assess how they would cope in the event of house prices crashing by 40 per cent.

The instruction to include a housing slump scenario in their stress-testing models comes after the Financial Services Authority found that some banks were failing to include gloomy enough assumptions in their modelling.

The FSA said yesterday that an "appropriate" benchmark was to assume property prices fell by 40 per cent and that 35 per cent of mortgages in default ended with homes being re-possessed. It stressed that this was not a forecast but a "severe but plausible scenario" and one that banks should examine when deciding how robust their balance sheets were.

In a speech to the British Bankers' Association yesterday, Clive Briault, the FSA's managing director for retail markets, remarked on banks' differing views over the size and impact of a house market downturn, hence the need for reference points.

He also warned bankers to ensure that they have properly stress-tested their mortgage portfolios in the wake of decisions by some to lend people greater multiples of their incomes.
