The Globe and Mail reports in its Friday edition that in the next three to four years, the banking sector will undergo significant transformation because of artificial intelligence, according to TD Bank chief executive officer Raymond Chun. The Globe's Stefanie Marotta writes that while AI has been used to lower costs and boost productivity, it is beginning to drive revenue. For example, TD has cut the time it takes to assess mortgage applications from 15 hours to about three minutes. The process allows employees to deliver loans faster and spend more time having conversations with customers. The bank is bulking up its front-line staff, adding 1,000 bankers in branches, 1,200 wealth advisers, as well as hundreds of mortgage, investment and business specialists. TD plans to provide each employee with a personal AI agent that would compile a summary of a client's portfolio, previous conversations and recommendations for products and services that better fit their needs. "This is going to be a dynamic space," Mr. Chun said. "The more we talk about it with our colleagues, the more they are seeing the benefits and the upsides."
