There should be an easy way around this and that's to open the account only in your husband's name. If you have no signing rights or power of attorney over it, then it doesn't have to be reported so theoretically they should agree to let you have an account.

Otherwise, try opening the account at another branch. People have reported here that after being refused in one branch they've been accepted at another; this has happened even at different UBS branches.

If neither work then try UBS or Credit Suisse. If they say no to a joint account again ask if they'll accept just your husband as signatory.
