The so called bad financial institution, the Northern Rock's has twisted in a huge profit for the first half of 2010, but the so the called good bank is jostling as retail deposits, its lifeline, and turn down.

A portfolio of £51bn comprising risky mortgages and unsecured loans crafted Northern Rock Asset Management £349.7m during the six months, with its first profit after the credit crunch and recoil from previous year's £724.2m loss.

Low interest rates denote hard-up homeowners have been now capable to search enough cash to pay the mortgage, slashing down the impairment charges to £277.6m from £602.2m.

The digits are first since the government-owned Rock that shall go down the lethal assets over the next 20 years, tear in two at the beginning of the year.

But it's an altogether a diverse story at the retail business, the good bank which is largely supported financially by retail deposit balances.

It mislaid £142.6m, as anticipated, and witnessed the retail deposits dwindle to £17.6bn from £19.5bn at the time of the reformation on 1 January.

The plummet was liable on the decision to close down its Guernsey savings operations, and the elating of the government's 100% guarantee of Newcastle-pedestal Rock's retail savings deposits in the month of February.
