The Financial Post reports in its Wednesday edition that blockchain technology could someday take a bite out of the fees and commissions charged by Canadian banks, according to Moody's Investors Service. The Post's Geoff Zochodne writes that the rating agency looked at two specific areas that could be affected by blockchain: cross-border transactions and fee income. Moody's found distributed ledger technology has the potential to cut down on the time and money connected to cross-border banking, but that it also raises risks for some revenue. Swiss banks may be most exposed to a blockchain-related disruption, as 50 per cent of revenue flows from fees and commissions, Moody's said. However, the next most exposed could be Canadian, Israeli and Italian banks because lenders from those countries derive around 35 per cent of their revenue from those sources. Moody's said blockchain technology is still at an "early stage," but the report comes as some Canadian banks are experimenting with ways to use the technology in their businesses. It has been taken seriously by some chief executives as well. Scotiabank chief executive officer Brian Porter has said blockchain "is going to have a huge impact on the future of banking."
