A U.S. Securities and Exchange Commission debate over whether planned tokenised securities rules would allow synthetic tokens prompted SEC Commissioner Hester Peirce (헤스터 피어스) to offer an unusual advance clarification of the unpublished rule.

On May 23 local time, CoinDesk reported that Peirce, who leads the SEC crypto task force, said on social media platform X (Twitter) that the forthcoming rules will not open the door to tokenised synthetic securities. She said that includes third-party issued tokens that reference securities but do not carry actual rights such as equity or voting rights.

Peirce said the rule is "limited in scope and will allow only the trading of digital representations of the same underlying stock that an investor can buy in today’s securities market. They are not synthetic products," she said.

The controversy was sparked after Bloomberg News reported this week that the SEC was leaning toward including synthetic tokens tradable on decentralised crypto platforms in its tokenised securities rules.

CoinDesk said the SEC rule will be a meaningful step in establishing a new regulatory approach to crypto trading in the United States. SEC Chairman Paul Atkins has said he will unveil a broad proposal in coming months to provide regulatory exemptions for the crypto sector.
