Summary:

Bank for International Settlements warns dollar stablecoins could impact financial stability if they scale further.
BIS General Manager Pablo Hernández de Cos urges stronger global coordination on regulation.
Tokens like Tether and USD Coin behave more like investment products than cash, according to BIS.
Concerns include run risks, pressure on banks, and gaps in AML oversight.
Europe and other regions are already moving toward tighter stablecoin rules.

The conversation around stablecoins is shifting again. At a recent seminar hosted by the Bank of Japan in Tokyo, the Bank for International Settlements made its position clear that dollar-backed stablecoins could become a real risk if their growth continues unchecked. Speaking at the event, Pablo Hernández de Cos warned that these tokens may carry "material consequences" for financial stability and economic policy if they begin to rival traditional forms of money. Stablecoins are still evolving, but their direction matters. According to his remarks, current stablecoin structures fall short of what would be required for a widely used payment system. While they offer speed and flexibility especially in cross-border transfers, they don't fully match the reliability expected from money used at scale and that gap becomes more important as adoption grows.

One of the more direct points raised in the speech was how stablecoins behave in practice. De Cos argued that major dollar-denominated tokens share more in common with investment products than with cash. He pointed to features like fees, redemption conditions, and price fluctuations in secondary markets. Even though stablecoins aim to maintain a one-to-one value with fiat currency, they don't always hold that peg perfectly. During periods of stress, prices can drift, even if temporarily. In that sense, assets like Tether and USD Coin start to resemble exchange-traded funds - instruments backed by underlying assets, but still subject to market dynamics. That structure introduces a specific kind of risk. Stablecoin issuers typically hold reserves in short-term government debt and bank deposits. If large numbers of users try to redeem their tokens at the same time, those reserves may need to be liquidated quickly. In a stable market, that might not be an issue. But in a stressed environment, forced selling could add pressure to already fragile financial systems. It could also transmit stress back into banks that hold parts of those reserves. The concern is based on similar mechanisms that have played out in traditional finance before.

Regulation Gaps and Global Pushback

Beyond market structure, the BIS also highlighted regulatory gaps - especially around stablecoins operating on public blockchains. A large share of activity takes place through permissionless systems and unhosted wallets. That makes it harder to apply standard Anti-Money Laundering and Counter-Terrorism Financing controls. Without tailored safeguards, these systems can become attractive for illicit use. This is where the call for global coordination comes in. Stablecoins don't operate within a single jurisdiction. They move across borders by design. That makes fragmented regulation less effective. The BIS is not alone in raising these concerns. Across Europe, policymakers are already moving in a similar direction.

Officials at the European Central Bank have drawn comparisons between stablecoins and tokenized money market funds, noting that both involve liquidity transformation and exposure to run risk. At the same time, they operate under different levels of transparency and oversight. In France, central bank officials have gone further, suggesting tighter limits on the use of non-euro stablecoins in everyday payments. The goal is to reduce reliance on dollar-backed tokens and limit regulatory gaps during periods of stress. The UK is also examining the issue closely. Lawmakers have raised concerns about whether stablecoins could pull deposits away from commercial banks or amplify risks similar to past banking crises. Meanwhile, in Switzerland, banks including UBS are testing domestic stablecoin models within controlled environments. These pilots aim to explore the benefits of blockchain-based payments while keeping systems tied to regulated financial infrastructure.

A Turning Point for Stablecoins

Stablecoins were initially seen as a bridge between crypto and traditional finance - a way to move value quickly without volatility. The BIS warning reflects a broader shift in tone and also questions around liquidity, transparency, and systemic impact are now taking center stage. At the same time, the industry continues to push forward. Stablecoins remain widely used across trading, payments, and decentralized finance. For many users, they are already part of everyday activity. According to Defillama, Total Stablecoins Market Cap crossed $320B.

Regulators want to reduce risk without slowing down innovation and companies want to expand use cases without triggering stricter controls. For now, the path forward looks like tighter coordination. But that coordination will take time and it will likely differ across regions. However, stablecoins are no longer operating on the edge of the financial system. They're moving closer to the center and with that shift comes a different level of responsibility.
