When a bank goes.....

..it goes quickly.

Here is the daily outflows from Northern Rock bank accounts during the run back in September 2007. When the run started, NRK were losing billions each day.

Although the government had given a blanket guarantee on deposits, the bank kept losing funding. By October 2007, customer deposits had shrunk to 15.3 per cent of the company’s funding (a drop from £30 billion to £17 billion); and wholesale
loans had fallen to 11.8 per cent (from £17 billion to £13 billion).

To cover this loss of funding, the Bank of England was forced to inject tens of billions of pounds. By February 2008, the BoE had over ₤50 billion invested in Northern Rock.

Wouldn't it have been so much better if the FSA had properly supervised it? I know; horse, bolt, barn door.
