The global stablecoin market has surpassed $284 billion in circulation, reigniting a long-running debate over whether the rapid growth of fiat-backed digital tokens threatens traditional banks or simply represents a new layer of financial infrastructure developing alongside them.
At the same time, a recent $2.24 billion dip in major stablecoins hints at near-term risk aversion among investors.
That question moved back into focus this week after historians and economists Niall Ferguson and Manny Rincon-Cruz argued that concerns about bank destabilization are overstated, even as banking industry groups intensify their opposition to stablecoin rewards.
Writing in a Bloomberg opinion piece, the authors framed stablecoins as fundamentally different from volatile crypto assets such as Bitcoin, emphasizing their role as payment instruments rather than speculative investments.
Stablecoins grow under new US framework
Ferguson and Rincon-Cruz contrasted speculative crypto tokens, which they said behave more like financial derivatives, with fiat-backed stablecoins whose growth has accelerated since the passage of the US GENIUS Act last summer.
The legislation created the first comprehensive federal framework for payment stablecoins, restricting reserves to cash, bank deposits, and short-dated US Treasuries, while prohibiting issuers from making loans or paying interest directly to tokenholders.
Since the law took effect, the sector has expanded rapidly.
Treasury Borrowing Advisory Committee data cited in the opinion piece show that fiat-backed stablecoins have surpassed $284 billion in circulation, with Tether’s USDT and Circle’s USDC accounting for more than 90% of total supply.
Treasury officials project that payments, trading liquidity, and cross-border settlement demand could grow to between $2 trillion and $3 trillion by 2028.
Why banks are pushing back
Banks, however, have pushed back against this expansion.
Industry groups including the American Bankers Association and the Bank Policy Institute, argue that large-scale migration of deposits into stablecoins, particularly when paired with rewards offered by exchanges or platforms, could raise banks’ funding costs and reduce credit availability.
JPMorgan executives have described interest-bearing digital dollars as the creation of a parallel banking system lacking equivalent safeguards.
The banking sector’s lobbying efforts to alter the proposed CLARITY Act, an expanded crypto market structure bill, triggered resistance from crypto companies and contributed to delays in Senate hearings.
Coinbase Chief Legal Officer Paul Grewal rejected claims that stablecoin rewards pose a threat to financial stability, saying there is no evidence of systemic risk and that competition should not be mistaken with instability.
Ferguson and Rincon-Cruz countered the banks’ arguments by pointing to historical precedent.
They said stablecoins are closer to bank notes than deposits and noted that historically, notes and deposits expanded together rather than crowding each other out.
They cited statistics showing that since USDC’s introduction in 2018, US bank deposits have grown by more than $6 trillion, while stablecoins increased by roughly $280 billion, with both moving in the same direction.
They also argued that stablecoin rewards are not a new phenomenon and have not caused deposit flight, even during periods when banks paid minimal interest.
Similar views were echoed by Circle CEO Jeremy Allaire at the World Economic Forum in Davos, where he said stablecoin rewards are comparable to loyalty programs in traditional finance.
Market volatility clouds near-term outlook
Despite long-term growth trends, short-term data point to headwinds.
A $2.24 billion drop in total stablecoin market capitalization over the past 10 days suggests capital may be leaving the crypto ecosystem, according to analytics platform Santiment.
In a post on X, Santiment said much of that capital has rotated into traditional safe havens such as gold and silver.
“A falling stablecoin market cap shows that many investors are cashing out to fiat instead of preparing to buy dips,” Santiment said, adding that rising demand for precious metals indicates that “investors are choosing safety over risk.”
Bitcoin has fallen sharply since October, while gold has surged more than 20% and silver has more than doubled in value.
Santiment noted that crypto recoveries historically begin when stablecoin supply starts to rise again, signaling renewed confidence.
Until then, it said, altcoins are likely to remain under pressure even if Bitcoin proves relatively resilient.
