Accredited Home Lenders and HSBC announced a combined loss of more than 2,000 US jobs on Wednesday in the growing impact of mortgage market turmoil.

Accredited Home Lenders, a US subprime lender, said it would cut more than 60 per cent of its workforce, shedding 1,600 jobs, to boost liquidity after private equity group Lone Star backed out of its $400m purchase of the company.
