Technology threatens jobs in many industries, but one bank chief is already predicting that "a lot of people" in his industry will see their roles taken by automation in the next five to 10 years.

Deutsche Bank CEO John Cryan has made headlines before for his prediction that technology will end many banking jobs, but he offered more insight into exactly how the financial world will change in an interview with CNBC on the sidelines of the Singapore Summit.

The banking sector, he said unequivocally, will see many of its current roles automated. In fact, Cryan said, "it would be inappropriate not to say that's the case — it's not specific to our bank, in fact it's a sector-wide phenomenon."

Right now, he explained, many finance jobs require people to act like robots, so they'll easily be replaced by robots. His employees already know it, he added, and there may even be a silver lining to their current roles going to the machines.

"The opportunity that we always talk about internally is upskilling the job, making jobs more satisfying," Cryan said. "People who are just mechanically moving paper and numbers around don't have a very fulfilling job, and the career prospects there are not as attractive as they would be if we were able to automate a lot of that production. Then we can add a bit of thinking and a bit of creativity to the role."
