Circle (CRCL) shares plunged more than 20% on March 24, with Coinbase (COIN) dropping roughly 8% in sympathy. The sell-off was triggered by a leaked draft of the U.S. Clarity Act, which seeks to tightly restrict or ban stablecoin issuers from paying passive interest or rewards to holders.
The magnitude of the drop reflects Circle's extreme valuation: shares had surged about 170% since early February, making them vulnerable to any negative headline.
Core Impact: Banning 'Passive Yield' Models
Prior legislation (the GENIUS Act) already prohibited direct interest payments to users. In response, Circle and Coinbase developed a 'pass-through model': Circle earns yield on USDC reserves (mainly U.S. Treasuries), shares part of that yield with Coinbase, and Coinbase passes it on to users as rewards. This yield mechanism has been a key driver of stablecoin adoption.
Keyrock digital assets researcher Amir Hajian noted that the latest Clarity Act draft explicitly forbids any form of reward that is 'economically equivalent to interest'. This effectively kills the pass-through model. Shay Boloor of Futurum Equities warned that without yield, USDC becomes little more than a payment rail, undermining its appeal as a store of value.
Competitive Pressure: Tether Audit Looms
Circle also faces intensifying competition from Tether. Tether has announced it hired a Big Four accounting firm to conduct a full reserve audit. If the audit passes smoothly, USDT's compliance profile could improve significantly among institutional investors, eating into USDC's market share.
Wall Street Views: Panic Overdone, Long-Term Case Intact
Most sell-side analysts view the sell-off as an overreaction. Three supporting arguments emerge:
- Coinbase could benefit short-term: Mizuho analyst Dan Dolev noted that USDC accounts for about 20% of Coinbase's revenue, much of which is spent on user rewards. If the ban eliminates that expense, Coinbase's net profit could rise.
- Market 'shoots first, asks questions later': Clear Street analyst Owen Lau said the reality is not as dire as the headlines suggest, and the sell-off reflects emotional panic.
- Compliant workarounds will emerge: Bitwise research head Ryan Rasmussen pointed out that Circle is still up more than 30% year-to-date despite the recent drop. He expects the industry to develop alternatives such as loyalty programs. "Circle's long-term outlook has never been brighter," he said, noting the company holds a 30% share in a market expected to grow 10x in four years.
