In this era of data breaches, that's exactly what the hackers are hoping for: That they'll figure out one of your more valuable logins based on the login they stole.
That's why you should try to never use the same password at sites of different need of security (and best if you never reuse a password exactly the same at all for any site where anything could be stolen from you).
Now, if you need a password to read a newspaper online, there's not that much harm that could come from having that password be stolen. But a bank???
