Lisa as an ex employee of HSBC and a shareholder I keep an eye on them but to the best of my knowledge they have no problems that the other banks donthave.All of which is down to what is called sub prime lending,basically all,yes all the big banks got suckered in by America(what a suprise) to in effect buy a lot of their mortgage lending ,however this coincided with a major downturn in the health of the american housing market (a bit like here) the result was vast numbers being unable to pay their mortgage as a result lots of repossesions that is always the case sell at below the amount owed.Result big loses to the banks.All financial institutions have to have sufficient funds to cover their liabilities,all the banks are well covered but as with the others they always err on the side of caurion and ensure that they are over covered,hence RBS and now HBOS issuing a rights issue to increase their cover which will mean that they are covered not only as rquird but also to cover any future effects of the sub prime lending.
I hope that helps,dont panic because Northern Rock had no problems until panic set in and they lost their cover due to fools causing a run on what was a sound bank,but none would survive that sort of activity.The rights isues would however reduce problems even in the event of a run.
