Clearly, your bank has changed their online billing app to use a third party cookie (because the actual app isn't hosted on the bank's servers?) or contracted with some outside source for tracking purposes or something similar.

I wouldn't expect a miraculous change in policy/practice though - as I noted, this doesn't appear to be unusual for US banks.
