Third Circuit Bolsters SEC Power, Dashes Coinbase Rulemaking Bid

COURT SLAPS COINBASE, HANDS SEC MORE POWER

The Third Circuit just backed the SEC’s refusal to write new crypto rules, giving the agency a stronger hand against exchanges and leaving Coinbase with fewer legal weapons to force regulatory change.

Coinbase filed a petition asking the appeals court to force the SEC to respond to the company’s earlier rulemaking petition, which sought clarity on how digital assets should be treated under federal securities law. The SEC had already denied that request, claiming it was too busy with enforcement actions and didn’t need new rules to police the space. Coinbase argued the denial was arbitrary, harmed the entire industry, and violated the Administrative Procedure Act. The Third Circuit disagreed, ruling the SEC’s decision was a lawful exercise of its discretion and that courts shouldn’t second-guess an agency’s priorities unless they’re clearly unreasonable.

The judges held that the SEC can choose to regulate by enforcement rather than rulemaking and doesn’t owe the public a detailed explanation every time it turns down a petition for new rules. That means Coinbase loses its bid for judicial intervention, and the SEC keeps its current playbook intact. The ruling effectively tells exchanges and token issuers they’ll have to fight enforcement cases one at a time instead of getting broad regulatory relief through the courts.

In plain terms, the court said the SEC can keep treating most tokens as securities, pursue cases without first spelling out the rules, and ignore industry pleas for clearer guidelines. That shifts more power to the agency, raises the stakes for any firm operating without registration, and leaves market participants guessing about which assets could trigger enforcement next.

The decision tilts authority toward the SEC at a moment when the agency is already ramping up actions against exchanges and staking programs. It also puts pressure on DeFi protocols and stablecoin issuers, because the court’s hands-off stance means those projects can’t count on future rule changes to shield them from existing securities laws. Traders and platforms will now price in higher compliance costs and greater legal risk, since the alternative path—petitioning for new rules and suing when denied—just got narrower.

This ruling locks in regulatory uncertainty as the default, so exchanges and issuers should plan for more enforcement, not less.
