Citadel Securities has officially asked the U.S. Securities and Exchange Commission (SEC) to impose stricter regulations on cryptocurrency markets, which has brought the ongoing conflict between traditional financial institutions and the rapidly growing sector of Decentralized Finance (DeFi) back into focus. The market maker is arguing that DeFi platforms offering tokenized versions of U.S. stocks should not receive any “exemptive relief” from existing securities laws, effectively demanding they play by the exact same rules as the New York Stock Exchange.
Leveling the Playing Field or Gatekeeping?
The issue of concern stems from a recent correspondence Citadel sent to the SEC. The letter was sent by Citadel in response to the SEC requesting feedback from the public as to how they should proceed with regards to digitising traditional types of assets. Citadel stated in their correspondence that they feel very strongly that allowing DeFi creators and/or developers of smart contract coders regulatory “hall passes” is opening up a Pandora’s Box and would set a very dangerous precedent giving a double standard to different market participants.
According to Citadel, a share of Apple stock should be treated the same way whether it is traded on a traditional brokerage app or swapped on a decentralized blockchain protocol. “Granting broad exemptive relief to facilitate the trading of a tokenized share via DeFi protocols would create two separate regulatory regimes for the trading of the same security,” the firm argued. They believe that creating separate registration categories would violate the Exchange Act’s requirement for technology neutrality. This would allow crypto exchanges to gain an advantage over traditional financial intermediaries that face regulatory oversight (i.e., through licensing and other regulatory mechanisms).
The Crypto Community Bites Back
Industry leaders in blockchain have reacted quickly and harshly to Citadel’s request, which they see not as a plea for fairness, but as an effort to eliminate competition that threatens the position of traditional financial intermediaries.
Jake Chervinsky, a lawyer and board member of the Blockchain Association, took to social media to voice the community’s frustration. “Whoever thought Citadel would be against innovation that removes predatory, rent-seeking intermediaries from the financial system?” Chervinsky asked sarcastically, before answering his own question: “Oh, right, literally every single person in crypto.”
Hayden Adams, the founder of the decentralized exchange Uniswap, echoed these sentiments. He suggested it was unsurprising that the “king of shady TradFi market makers” would oppose open-source, peer-to-peer technology designed to lower the barriers to liquidity creation.
Redefining the “Broker-Dealer”
At the heart of Citadel’s legal argument is the definition of who exactly is facilitating these trades. In the world of DeFi, trading happens via smart contracts—automated code—rather than through a human broker or a centralized company. However, Citadel contends that these platforms, and the developers who build them, essentially function as “exchanges” or “broker-dealers” under the law.
As such, they contend that all of these entities need to register with the SEC, which is a source of controversy due to the fact that numerous DeFi advocates have said that the creators of software are just creating code and are not in possession of the funds of users; hence, they are not subject to regulation in the manner of traditional banking institutions or broker-dealers.
Traditional Finance Rallies Together
Citadel is not shouting into the void; they have powerful backing from other corners of the financial establishment. The Securities Industry and Financial Markets Association (SIFMA), a major trade group, issued a similar statement supporting Citadel’s view. They emphasized that tokenized securities must be subject to the same fundamental investor protections as traditional stocks.
SIFMA pointed to recent volatility in crypto markets—specifically referencing the October flash crash—as “timely reminders” of why strict regulatory frameworks exist. The World Federation of Exchanges has also weighed in, urging the SEC to abandon any plans to grant an “innovation exemption” to crypto companies.
Innovation at Risk?
For advocates of blockchain technology, the stakes couldn’t be higher. Summer Mersinger, CEO of the Blockchain Association, warned that applying old-world rules to new-world technology could have disastrous consequences for the American tech sector.
“Regulating software developers as if they were financial intermediaries would undermine US competitiveness, drive innovation offshore, and do nothing to advance investor protection,” Mersinger stated. She urged the SEC to reject Citadel’s “overbroad and unworkable” approach and instead focus on regulating actual intermediaries who hold custody of user assets.
The comments being reviewed by the SEC are indicative of an ongoing battle between two competing ideologies in finance. One side represents the traditional financial system that has been around for centuries and desires consistency and safety in the marketplace while on the other side is a new breed of financial entrepreneur who believes they should have the right to create and innovate free from the burdensome regulations that have been placed on the industry for over 100 years.
