No banks doesn't deal with bitcoin because bitcoin is still not considered as legal money in our country so till now no banks accept bitcoin. but banks are making themself ready for future with such own currency.
What are they going to do by creating virtual currency ,they might start using block chain but i do not think any bank will be planning to start their own crypto currency as it is meaningless for them to start one unless they wanted to make some quick money under the direct order of a government.
I do have my exchanges that accepts bitcoin and if i want i will transfer it to my bank account if i want to and i do not need banks to handle my bitcoins.
