Massachusetts Democrat Senator Elizabeth Warren has again stepped into the limelight for her comments about the fast-growing sector of decentralized finance (DeFi) and the role of stablecoins in this niche.

Speaking at a Senate Committee on Banking, Housing, and Urban Affairs hearing on Tuesday, Warren described stablecoins as “the lifeblood of the DeFi ecosystem,” where they are used to trade between different coins, as well as to lend and borrow money outside the regulated banking system.

Stablecoins are cryptocurrencies that claim to be pegged 1:1 to fiat currencies like the U.S. dollar, meaning that, unlike Bitcoin or many other cryptocurrencies in the market, their prices are supposed to remain steady.

Warren also stated that stablecoins pose risks to consumers and the economy because they are “propping up one of the shadiest parts of the crypto world, DeFi, where consumers are least protected from getting scammed.”


According to Warren, DeFi “is where the regulation is effectively absent and—no surprise—it’s where the scammers and the cheats and the swindlers mix among part-time investors and first-time crypto traders.”

“Our regulators need to get serious about clamping down before it is too late,” she said.

At the same hearing, Warren’s fellow party member, Senator Sherrod Brown labeled stablecoins as “magic money,” saying that they are neither decentralized nor transparent.


“If you put your money in stablecoins, there’s no guarantee you’re going to get it back,” warned the Ohio senator.

Warren’s ongoing war on crypto

Senator Warren’s latest comments on DeFi and stablecoins are just the latest episode in her ongoing criticism of the larger crypto industry.

In July, Warren sent a letter to Treasury Secretary Janet Yellen asking for greater oversight of the crypto industry.

“All the warning signs are flashing,” Warren said at the time. “The hype, the volatility, the wild claims that turn out to be false. As the crypto market grows, so do the risks to our financial stability and our economy.”

Earlier this month, pretty much in line with the popular climate change narrative, she also took aim at New York-based Bitcoin mining firm Greenidge Generation, raising concerns about its impact on the environment.

Prior to that, in an interview with CNBC, Warren stated that “one of the easiest and least disruptive things we can do to fight the climate crisis is to crack down on environmentally wasteful cryptocurrencies.”
