Corporate compliance issue

[jaxjob]

I work for a computer company that supplies desktop support services to an international investment bank. The bank's compliance dept recently had a meeting with us and sent us compliance forms that we must sign. The compliance agreement is that we will supply our social security number to the bank, along with all personal investment account information, including that of our spouses or other relatives living in our household. This includes the name of the brokerage firm we use, our account numbers, and we also have to get approval by someone at the bank if we want to do a trade. This is even if we don't have investment accounts with this particular bank. We are also supposed to notify them of any outside business ventures we may have. The reasoning is that, in doing our desktop support job, we may see something on the computer of one of the bank's employees that may influence us to invest in a stock. Basically they are looking at an insider trading issue. My question is does the bank have the right to ask me for all this information on my private accounts, as well as my social security number? As I said, I'm not a bank employee, just a contractor working at the bank. I have a problem giving the bank this info about my accounts, never mind my spouse's account info and social security number, who doesn't even work for the bank. If I refuse to give this info, and I am terminated because of it, do I have any legal rights? Isn't this a personal privacy case?
