Are Stablecoins a Threat to Traditional Bank Deposits?

A battle is brewing between Wall Street and the crypto industry over the future of money. Traditional banks are sounding the alarm that stablecoins—especially those offering interest—could trigger a mass exodus of deposits, but financial experts and regulators say the evidence for this is thin, at least for now.

The debate has reached a fever pitch as U.S. lawmakers consider the CLARITY Act, a crypto regulation bill. A proposed version supported by the banking sector would prohibit stablecoins from paying yield, a move fiercely opposed by the crypto industry. Banks claim this is a necessary safeguard, while critics call it protectionism.

The Banking Sector's Core Concern

Major financial institutions argue that allowing stablecoins to offer yield could directly siphon funds away from the traditional banking system. A recent research note from Standard Chartered projected a significant impact, estimating that U.S. bank deposits could fall by an amount equal to one-third of the total stablecoin market capitalization.

With the stablecoin market currently valued at $308.15 billion, according to DeFiLlama, this represents a substantial potential drain. The logic is straightforward: if deposits leave banks, the banks have less capital to lend, which could reduce the supply of credit available across the economy.

A Theoretical Threat, For Now

Despite the banks' warnings, policy experts remain unconvinced of an immediate crisis. Aaron Klein, a senior fellow at the Brookings Institution, noted that there is "little evidence that stablecoins have drained bank deposits" so far. He explained that their primary uses have been for crypto-native activities and as a store of value in countries with volatile currencies.

European regulators seem to agree. A representative from the European Banking Authority (EBA) stated that since stablecoin use by consumers in the EU is low, the authority does not see current risks of currency substitution or capital flight.

However, both Klein and the EBA acknowledge this could change. Klein highlighted that the core of the banking sector's argument is forward-looking: "if stablecoins take off as their supporters claim they will, then it will likely result in a drain in bank deposits."

The EBA also warned that a significant increase in stablecoin adoption could introduce "financial stability risks," including bank run scenarios, cross-border legal issues, and regulatory challenges. Still, the representative clarified that a major shift away from euro-denominated assets toward U.S. dollar-backed stablecoins is "not foreseen in the EU."

One official from a major EU central banking organization suggested a more optimistic view, stating that well-regulated, euro-based stablecoins and tokenized deposits could actually enhance Europe's "strategic autonomy" by reducing reliance on foreign alternatives.

Crypto Leaders Push Back on Deposit Flight Claims

The crypto industry dismisses the banks' concerns as unfounded and anti-competitive. Jeremy Allaire, CEO of stablecoin issuer Circle, called the idea of stablecoin-induced bank runs "totally absurd" during a discussion at the World Economic Forum. He argued that while yields can help with "customer traction," they are not powerful enough to undermine monetary policy.

Colin Butler, head of markets at Mega Matrix, warned that banning yield on compliant stablecoins would only push capital offshore, beyond the reach of U.S. regulators, ultimately failing to protect the financial system.

Anthony Scaramucci, founder of SkyBridge Capital, offered a blunter assessment, claiming that banks simply "do not want the competition from the stablecoin issuers, so they're blocking the yield."

He pointed to China as a key example of a global competitor moving in the opposite direction. In January, the People's Bank of China authorized commercial banks to pay interest on digital yuan deposits. Scaramucci argued this gives China a competitive edge.

"In the meantime, the Chinese are issuing yield," he said. "So what do you think the emerging countries will choose as a rail system, the one with or without yield?"
