Negative equity risk looms

In its twice-yearly Financial Stability Report, the bank said a 15 percent drop in prices from their October 2007 peak would leave one in 10 homeowners with outstanding mortgage debt worth more than the value of their home.

"House price forecasts suggest further falls, although the size of these falls is highly uncertain," the report said.

A global shortage of capital has forced many banks to restrict lending, choking the country's housing market. Prime Minister Gordon Brown warned last week that Britain is likely to suffer a recession.

The bank's report said house prices have dropped faster in Britain than in the United States. They are down 13 percent from their peak and are close to the total nominal fall seen during the last recession in the early 1990s.

First time buyers would be among those hardest hit by falling house prices, the bank added. They are more likely to have had a smaller deposit and would have borrowed more to get a foot on the housing ladder, making them more vulnerable.

Buy-to-let landlords may fall behind on mortgage payments or be forced to sell at a loss as lending dries up and their investments lose value, the report added.

Two further sets of figures provided more bleak news for the housing market on Tuesday.

The Financial Services Authority said the number of home repossessions in the second quarter rose to 11,054 from 9,172 in the previous three months.

The Land Registry said house prices in England and Wales fell by eight percent on the year in September to their lowest level in two years. The average price in September was 168,814 pounds, a fall of 2.2 percent on the month.

However, mortgage lender Abbey National said in a trading update that the support of its Spanish owner had helped it win new mortgage business in a shrinking market and attract new deposits from rivals.

Abbey, bought by Santander in 2004, said it had added 1.4 billion pounds in deposits in the third quarter and total inflows in the nine months to the end of September were 70 percent higher than a year earlier.
