Google will offer checking accounts next year as it partners with financial institutions including Citigroup, representing Big Tech's boldest move yet into consumer banking.

Most previous efforts have focused on credit cards and payment platforms.

As part of a project code-named Cache, the company will become the latest Silicon Valley leader to try its hand at the banking space, the Wall Street Journal reported. Previous attempts by Apple and Facebook faced obstacles, with consumers growing increasingly skeptical over providing large technology companies with their personal information.

"We're exploring how we can partner with banks and credit unions in the US to offer smart checking accounts through Google Pay, helping their customers benefit from useful insights and budgeting tools, while keeping their money in an FDIC or NCUA-insured account," a Google spokesman said in a statement. "We look forward to sharing more details in the coming months."

Google does not intend to sell customers' data, Caesar Sengupta, an executive at the firm, told the Journal.

"If we can help more people do more stuff in a digital way online, it's good for the internet and good for us," Sengupta said.
