"Facebook, I believe, has made quite broad rounds around the world, really, with regulators, supervisors and lots of people to discuss their plans," Powell said during a press conference in Washington, D.C. "And that certainly includes us."
"We meet with a broad sector all the time," he added. "There's just a tremendous amount of innovation going on out there."
On Tuesday, the social media giant unveiled details about Libra, a new cryptocurrency powered by blockchain, and Calibra, a digital wallet that can be used to save, send and spend Libra.
Facebook said it will lead a number of big-name investors -- including Visa, PayPal and Uber -- to create Libra, which is currently set to launch at the beginning of 2020.
Powell noted, however, that the Fed does not exercise "plenary authority" over cryptocurrencies -- nor does it plan to regulate it anytime soon.
