HSBC does not need to move its head office to HK to benefit from a tax shield. Barclays were able to illustrate just that recently by announcing having paid 2% in tax in their last results.I still rest my case. HSBC could have decided to move next year, last year, the year before...absolutely nothing to do with economic recovery.The UK economic recovery is probably the least of our worries right now anyway. global oil supply is certainly more relevant than corporations shifting head offices around.OPEC and Saudi Arabia are more than likely to plug the current global supply shortage but if the turmoil in the middle east starts to cross the borders of Saudi Arabia, we are well and truly f*****If that happens, I would encourage you to put your money in rail companies because they will make a killing once oil hits $200/ brrl
