Maybe time to brush up ye olde CV and look around?
Any of the other banks have similar departments that you know of? See what training you can get out them them?
A friend who works at the Didcot power station is rinsing them for all the training he can get and also paying for a few courses himself for when it gets shutdown and made redundant in a few years. He's doing a health and safety course in a few months, costing around £400 he said, which means he can then go and audit companies H&S policies and do consulting etc for a tidy sum.
Just a thought that you might want to change career paths and get some training done now, could work out for the best?
