Analysts said that the Bank of England had clearly learned from the dithering by the authorities over the collapse of Northern Rock last year and the much faster rescue over last weekend of Bear Stearns in the United States. The Financial Services Authority, the City watchdog, aggressively warned stock market traders that it would not tolerate abuse of the stock market by people spreading false rumours and then trying to make a profit. Sally Dewar, head of the FSA's wholesale markets, said: "There has been a series of completely unfounded rumours about UK financial institutions in the London market over the last few days. We will not tolerate market participants taking advantage of the current market conditions to commit abuse by spreading false rumours and dealing on the back of them." HBOS has more private shareholders than any other company in Britain. Its 2.1 million small shareholders are almost all customers of the bank. In the last six months they received £130 million in dividend. Halifax is Britain's biggest mortgage lender with outstanding loans of £430 billion.
