Stablecoins have become one of the most talked-about corners of digital finance. They are often described as a bridge between traditional money and crypto assets: digital tokens that aim to offer the speed and convenience of blockchain-based payments without the price volatility that makes most cryptocurrencies unsuitable for everyday use. But the latest warning from one of the world’s leading central banking institutions suggests that the gap between stablecoin ambition and real-world payment credibility is still wider than many people think.
Pablo Hernández de Cos, chief of the Bank for International Settlements, said that stablecoins are not yet credible for payments at scale. That statement matters because it does not come from a fringe critic or a competitor in the payments space. It comes from a figure closely connected to the global monetary system, where trust, stability, and institutional confidence are the foundation of everything from settlement to consumer protection.
The comment also arrives alongside a new study from the Financial Stability Institute, which highlights sharp differences in the rules governing stablecoin issuers. Taken together, the two messages point to a core issue: stablecoins may be useful in specific niches, but turning them into a broad payment rail requires far more than technical innovation. It requires legal clarity, operational resilience, regulatory alignment, and a level of public trust that has not yet been established.
Why payments at scale are a different challenge
A payment system used by a handful of early adopters is not the same as one used by millions of consumers, merchants, banks, and businesses. At scale, a payment rail has to work reliably under stress. It has to handle large volumes, support dispute resolution, protect users from fraud, and maintain confidence even during market turbulence or operational failures.
For stablecoins, that means proving several things at once. First, the token must be redeemable in a predictable way. Second, the reserves behind it must be transparent, safe, and sufficient. Third, the issuer must be subject to rules that give users and regulators confidence that the system will not collapse when pressure rises. Fourth, the broader financial system must be able to integrate the stablecoin without creating new channels of risk.
None of these requirements is impossible to meet. But they are not met simply by launching a token, listing it, or marketing it as “stable.” Credibility in payments is built over time, through consistent behavior, clear legal rights, and institutions that people believe will stand behind the system when it matters most.
Credibility is about trust, not just token design
One of the reasons stablecoins have attracted attention is that they can appear, at first glance, like a simple solution: a digital dollar or euro that moves quickly across borders, without the delays and fees associated with traditional correspondent banking. In theory, that is compelling, especially for cross-border payments and remittances, where costs and speed have long been major pain points.
But a token that merely tracks a fiat currency is not automatically as trustworthy as the fiat currency itself. If the issuer holds reserves in risky assets, if redemption rights are unclear, or if the token is treated differently in different jurisdictions, then users are carrying more uncertainty than they may realize. For small payments, that uncertainty might be tolerable. For large-scale payments, it is not.
Merchants, banks, and institutions are unlikely to build their core operations on a payment instrument unless they have strong confidence in its legal status and operational reliability. That is why the BIS chief’s emphasis on credibility is so significant. It shifts the conversation away from whether stablecoins are innovative and toward whether they are dependable enough to become part of the mainstream financial system.
The FSI study points to a patchwork of rules
The new Financial Stability Institute study adds another layer to the discussion by highlighting sharp differences in issuer rules. In other words, stablecoins are not being regulated—or even defined—in a consistent way across markets. Some issuers may be subject to banking-like oversight, while others may operate under lighter frameworks. Some may be required to hold high-quality reserves, while others may have more flexibility in how they manage assets backing their tokens.
That patchwork creates several problems.
- Legal uncertainty: Users and businesses may not always know what rights they have if a stablecoin fails or if redemption is restricted.
- Comparability problems: Two tokens marketed as “stable” may have very different levels of safety and transparency.
- Cross-border friction: A stablecoin that works in one jurisdiction may not be recognized or treated the same way in another.
- Systemic risk concerns: If large amounts of value move through stablecoin systems with uneven rules, the financial system may face new vulnerabilities.
For payments at scale, consistency matters. A user sending money to another country should not have to navigate a confusing mix of local rules, issuer terms, and redemption restrictions. A bank integrating stablecoin settlements should be able to rely on a clear standard of oversight. A merchant accepting stablecoins should know that the system behind the token is designed to hold up under normal conditions and, importantly, under stress.
What this means for stablecoin projects
For stablecoin issuers, the message from the BIS chief and the FSI study is that the next phase of growth will depend less on marketing and more on institutional trust. Projects that want to be taken seriously in payments will need to focus on governance, transparency, reserve quality, and regulatory engagement. They will also need to think carefully about how their products fit into the broader financial architecture, rather than assuming that they can operate as a parallel system with minimal connection to public institutions.
This does not mean stablecoins are dead or irrelevant. Far from it. They may still play important roles in treasury management, settlement, cross-border payments, and digital asset ecosystems. But the bar for large-scale consumer payments is much higher. To cross it, stablecoins will need to demonstrate that they can function as part of a trusted financial system, not just as a fast-moving token on a blockchain.
Regulation will likely become a central battleground
As stablecoins grow, regulators will face a difficult balancing act. They will want to encourage innovation and reduce friction in payments, but they will also need to protect consumers, preserve monetary stability, and prevent the emergence of new risks in the financial system. The FSI study suggests that the current approach is too fragmented to provide that balance easily.
Over time, we may see more coordination among regulators, especially
