The proposed restrictions on stablecoin yields under the US CLARITY Act risk driving capital out of regulated markets and into offshore, opaque financial structures, creating a paradoxical outcome that undermines the very stability it seeks to achieve while eroding America’s competitive edge in the rapidly evolving global digital economy. This legislative initiative, ostensibly designed to protect the US financial system, instead threatens to sideline regulated domestic institutions and accelerate a significant migration of capital beyond direct US oversight, funneling it into less transparent and potentially riskier environments.

The CLARITY Act, alongside the recently enacted GENIUS Act, represents a concerted effort by US lawmakers to establish a comprehensive regulatory framework for stablecoins. While the intent is to mitigate systemic risks and protect consumers, a key provision within this framework prohibits payment stablecoins from offering interest directly to holders. Under the GENIUS Act, payment stablecoins such as USDC must be fully backed by cash or short-term Treasuries, effectively treating them as digital cash rather than interest-bearing financial products. This approach, however, has drawn sharp criticism from industry experts who argue it fundamentally misinterprets market dynamics and investor behavior.

Colin Butler, head of markets at Mega Matrix, articulated this concern clearly, stating that banning compliant stablecoins from offering yield would not safeguard the US financial system. On the contrary, he believes it would create a regulatory vacuum, allowing less scrupulous actors to fill the void. "There’s always going to be demand for yield," Butler told Cointelegraph, highlighting a fundamental principle of financial markets. He stressed that if legitimate, compliant stablecoins are prevented from meeting this demand, capital will inevitably seek alternatives, whether "offshore or into synthetic structures that sit outside the regulatory perimeter." This migration represents a significant challenge to US regulatory authority and its ambition to foster a secure and innovative digital asset ecosystem.

The core of Butler’s argument lies in the inherent structural imbalance created by the current legislative proposal. At a time when three-month US Treasuries yield around 3.6%, traditional bank savings accounts offer significantly lower rates, often hovering near zero. This disparity presents a clear incentive for investors to seek better returns. Banks, in their traditional model, benefit from this spread, paying depositors minimal interest while earning higher returns on their investments and loans. Butler contends that the "competitive dynamic for banks isn’t stablecoins versus bank deposits," but rather banks’ practice of paying very low rates to depositors while retaining the substantial yield spread for themselves. He emphasized that if investors can earn 4% to 5% on stablecoin deposits through exchanges, compared with near-zero yields at banks, capital reallocation is not just plausible but a "rational outcome" driven by basic economic principles. This perspective reframes the debate from one of unfair competition to one of market efficiency and consumer choice. By denying compliant stablecoins the ability to offer competitive yields, the US risks stifling innovation that could otherwise benefit consumers by providing more accessible and efficient ways to earn returns on their digital assets.

The potential for capital flight extends beyond simple relocation to offshore exchanges. Andrei Grachev, founding partner at Falcon Finance, warned that limiting onshore yield could create a vacuum that would be readily filled by so-called "synthetic dollars." These instruments, while pegged to the dollar, maintain parity not through one-to-one fiat reserves but through complex structured trading strategies, often involving various cryptocurrencies, derivatives, and perpetual futures. This distinction is crucial because it places them outside the regulatory scope of the GENIUS Act, which specifically targets fiat-backed payment stablecoins.

"The real risk isn’t synthetics themselves – it’s unregulated synthetics operating without disclosure requirements," Grachev clarified. He pointed out that while synthetic instruments can offer innovative ways to manage risk and generate yield, their unregulated proliferation poses significant dangers to market integrity and investor protection. Without transparent audits, clear collateralization standards, and robust disclosure, these products can become breeding grounds for systemic risk, potentially leading to instability that dwarfs the concerns currently driving the CLARITY Act.

Butler cited Ethena’s USDe as a prominent example of such a synthetic dollar. USDe generates its yield through sophisticated delta-neutral strategies, which typically involve holding a spot position in a cryptocurrency (e.g., Ethereum) and simultaneously shorting an equivalent amount via perpetual futures contracts. This strategy aims to neutralize the price volatility of the underlying crypto collateral while capturing the funding rates from the perpetual futures market. Because USDe and similar products fall outside the GENIUS Act’s narrow definition of payment stablecoins, they operate in a significant regulatory gray area. This ambiguity allows them to offer attractive yields, thereby attracting capital that compliant, yield-banned stablecoins cannot. "If Congress is trying to protect the banking system, they have inadvertently accelerated capital migration into structures that are largely offshore, less transparent, and completely outside US regulatory jurisdiction," Butler concluded, highlighting the unintended consequences of overly restrictive legislation.

The banking sector has been a vocal proponent of stablecoin yield bans, arguing that interest-bearing stablecoins could trigger massive deposit outflows from traditional banks, thereby weakening their lending capacity and impacting the broader economy. Deposits are indeed central to the fractional reserve banking system, providing the capital base for loans that fuel economic growth. However, Grachev argued that framing the issue as unfair competition misses a critical point. "Consumers already have access to money markets, T-bills, and high-yield savings accounts," he said, underscoring that stablecoins merely extend this access into crypto-native environments where traditional financial rails are often inefficient, slow, or inaccessible. Stablecoins offer a more seamless, 24/7, and often cheaper way for individuals and institutions to access dollar-denominated yield, particularly for those operating within the digital asset ecosystem. By stifling this innovation, the US risks denying its citizens and businesses access to more efficient financial tools, pushing them towards less regulated alternatives or foreign jurisdictions that embrace such innovation.

Beyond domestic concerns, the proposed yield bans carry significant global competitive implications, potentially undermining the US dollar’s long-standing dominance in international finance. Butler warned that the US cannot afford to act in isolation while other major economies are actively developing more progressive frameworks for digital currencies. China, for instance, introduced interest-bearing features for its digital yuan earlier this year, signaling a strategic move to enhance its attractiveness and utility. Similarly, jurisdictions such as Singapore, Switzerland, and the United Arab Emirates are actively developing regulatory frameworks and piloting projects for yield-bearing digital instruments, recognizing the potential for these innovations to attract capital and talent.

"If the US bans yield on compliant dollar stablecoins, we’re essentially telling global capital: choose between zero-yield American stablecoins or interest-bearing Chinese digital currency. That’s a gift to Beijing," Butler asserted. This stark comparison highlights a critical geopolitical dimension. The US dollar’s role as the world’s primary reserve currency is partly due to its stability and the depth of US financial markets. By restricting innovation in dollar-denominated digital assets, the US risks ceding ground to competitors who are embracing these technologies. If other nations offer more attractive and functional digital currencies, global capital may gradually shift away from dollar-backed digital assets, potentially eroding the dollar’s influence in the long run. This move would not only diminish US financial leadership but also impact its geopolitical leverage.

Grachev further argued that the US still possesses a crucial opportunity to lead in this nascent field by setting clear, robust standards for compliant, auditable yield products. Such a framework could provide a blueprint for responsible innovation, attracting capital and fostering trust. However, he cautioned that the current CLARITY Act draft risks doing the opposite. By treating all yield as equivalent and failing to distinguish between transparent, regulated structures and opaque alternatives, the legislation risks pushing the entire industry toward the latter. A more nuanced approach would involve classifying different types of stablecoins and yield-generating mechanisms, implementing tailored regulatory requirements based on risk profiles, and ensuring robust disclosure and audit mandates. This would allow for innovation to thrive within a controlled environment, rather than forcing it into the shadows.

In conclusion, while the CLARITY Act’s intentions to safeguard the financial system are understandable, its proposed ban on stablecoin yields represents a significant misstep. It overlooks the fundamental market demand for yield, inadvertently incentivizing capital flight to less regulated offshore markets and complex synthetic structures. This approach not only threatens to undermine the US’s regulatory oversight but also risks stifling domestic innovation and eroding its global competitiveness in the digital finance arena. By failing to offer a path for compliant, yield-bearing dollar stablecoins, the US could inadvertently hand a strategic advantage to rival nations like China, who are actively developing interest-bearing digital currencies. A more pragmatic and forward-thinking regulatory strategy would embrace the demand for yield, establishing clear standards for transparent and auditable yield products, thereby allowing the US to lead in the digital age rather than retreating from its inherent dynamism. Such an approach would protect consumers, foster innovation, and secure the dollar’s preeminence in the evolving global financial landscape.
