In addition to blocking Facebook's plans for Libra, the "Keep Big Tech Out of Finance Act" would prevent other firms (those mainly offering an online platform service with at least $25 billion in annual revenue) from launching similar cryptocurrencies. Companies that violate the rules could be fined as much as $1 million per day.
As Reuters notes, it's unlikely the legislation will pass, but it does reveal a growing attitude of skepticism toward big tech companies, especially those looking to enter the financial services realm. Tomorrow, Facebook plans to assure US lawmakers that it won't launch Libra until the regulatory concerns are addressed. David Marcus, head of Facebook's digital wallet, released a prepared statement promising that Libra is not being built to compete with sovereign currencies or interfere with monetary policy. Given Facebook's track record of handling things like data privacy and the skepticism around Libra, it's too soon to say if that will be enough.
