how to make use of gamification in financial/personalbanking?

I'm working on a project for a bank X and we were asked to increase engagement in using the website of the bank and provide more interactions with the bank in a way of gamification. its very problematic because in games people like to compare their scores etc. and here we cant share personal information to other users... earning awards for doing tasks is also boring.

Do you have any ideas of benchmark what could be a sorce of inspiration for us?

thx
