PNC Financial Services Group Inc. is considering charging financial-technology companies for access to valuable customer data, following the lead of JPMorgan Chase & Co., Chief Executive Officer Bill Demchak said. The bank is in “discussions” to determine what actions to take, Demchak said. JPMorgan has sent pricing sheets to data aggregators outlining proposed charges that could amount to hundreds of millions of dollars. “I applaud” what JPMorgan did, Demchak said. “There’s a big cost to keeping this data secure and producing it in a form that’s readable for our clients. So we’re thinking about it.” The charges could upend business models and potentially affect fintechs that rely on access to bank account information, like peer-to-peer payment platforms or cryptocurrency wallets. “American consumers, not banks, own their financial data, and big banks are taking advantage of this moment of regulatory uncertainty to crush competition and undermine innovation,” Lee said.
