PPRuNe Pop,
As others have said, these are known as "Phishing" and are incredibly common.
I have reported these instances to each bank
Good, but don't forget to include the full email including full headers when you do so.
but have heard nothing
Quite normal. Most ISPs don't reply to individual spam reports either.
The people operating the attacks will change URLs on a very regular basis, therefore a "live" URL today (or even this minute) will not be in use the next.
If you want to go further, you can do an nslookup/dig on the host, find the IP, report to the hosting ISP.... but to be honest, given the speed at which the URLs change chances are by the time you've figured out all that detail, they have either already been taken offline at that URL or have moved elsewhere.
