Gary Gensler served as Chairman of the U.S. Securities and Exchange Commission (SEC) from April 2021 to January 2025. His tenure was defined by an aggressive enforcement-first approach to cryptocurrency regulation that drew both praise and sharp criticism.
SEC Chairmanship and Crypto
As SEC Chair, Gensler maintained that most cryptocurrencies (other than Bitcoin) qualified as securities under existing U.S. law and that crypto exchanges were operating as unregistered securities exchanges. Under his leadership, the SEC brought enforcement actions against numerous crypto firms, including Coinbase, Kraken, Binance, and Ripple.
Gensler’s approach — often described as “regulation by enforcement” — was criticized by the crypto industry for providing no clear regulatory framework while pursuing cases that many believed stretched the boundaries of existing securities law. Supporters argued he was protecting investors from fraud and bringing necessary accountability to an industry rife with scams.
Bitcoin ETF Approval
In a seemingly contradictory move, the SEC under Gensler approved 11 spot Bitcoin ETFs in January 2024, following a court ruling that the agency’s prior rejections were “arbitrary and capricious.” The approval opened the door for mainstream institutional investment in Bitcoin through traditional brokerage accounts and became one of the most successful ETF launches in history.
Background
Before the SEC, Gensler taught a course on blockchain and cryptocurrency at MIT’s Sloan School of Management, where he expressed nuanced and sometimes positive views about crypto technology. Earlier in his career, he served as Chairman of the Commodity Futures Trading Commission (CFTC) and as a partner at Goldman Sachs, where he became the youngest person to make partner in the firm’s history.
Departure
Gensler resigned as SEC Chair in January 2025 ahead of the incoming administration, which had campaigned on a more crypto-friendly regulatory posture.
