Ten years after Lehman Brothers collapsed, high-octane products like those which led to the destruction of the American banking giant are making a comeback.

A decade ago Lehman heavily pursued subprime mortgage-backed loans, which were put into complex bundles obscuring their risk and value. This left the firm highly exposed to movements in the housing market and eventually triggered the biggest bankruptcy in US history.

These mortgage-backed securities which have become the most identifiable trigger for the financial crisis are now attracting fresh interest among investors. This is despite some market experts describing the housing market as a "bubble on a bubble".

Subprime mortgage lender, Belmont Green, has packeted up and sold more than £1bn of mortgages to investors with high housing market risk appetites, according to The Mail on Sunday.

Those linked to this effort have included former bosses from failed bank Northern Rock, Adam Applegarth, and Lesley Sewell. Guy Batchelor, former senior vice president at Lehman’s european mortgage division, is also now director of sales and marketing for Vida Homeloans, the trading name of Belmont. The lender is controlled by US private equity firm Pine Brook.
