The Bank for International Settlements delivered a blunt message to the crypto industry this week: stablecoins are not yet ready to handle everyday payments at scale. The warning, delivered by BIS General Manager Pablo Hernandez de Cos, arrives just as the United States, European Union, and a handful of other major economies are racing to finalize the rulebooks that will govern how stablecoins actually operate. For an asset class that has grown from a crypto-trading tool into a genuine contender for mainstream payments, the timing puts a global regulator’s skepticism on a collision course with an industry moving full speed ahead.
Why This Is Trending Now
Stablecoin regulation has moved from a policy debate into an active rulemaking process this year. In the United States, the Treasury Department proposed the core regulations implementing the GENIUS Act in August 2026, setting a January 2027 deadline after which only licensed issuers can legally issue payment stablecoins. The Office of the Comptroller of the Currency has said its own version of the rule will be finalized by November. Against that backdrop, the BIS stepping in with a note of caution carries extra weight, since it suggests the institutions writing the rules and the institutions setting global banking standards are not entirely aligned on how fast stablecoins should be allowed to scale.
What Happened?
Speaking this week, de Cos pointed to weak interoperability between different stablecoin platforms, inconsistent anti-money-laundering controls, and risks to bank funding as reasons stablecoins remain unsuited for widespread everyday use. He argued that tokenized bank deposits offer a more direct route to digital payments while preserving existing monetary infrastructure, though he acknowledged tokenized deposits face their own unresolved challenges around interoperability, governance, and settlement. The BIS also flagged a structural question regulators are still working through: whether a non-bank stablecoin issuer could place higher-risk activities such as lending or staking inside an affiliated company to sidestep restrictions placed on the issuer itself, an issue that has increased interest in group-wide supervision of stablecoin businesses.
What It Means for the Industry
The BIS’s caution lands alongside genuinely fast-moving state and federal rulemaking. Treasury’s proposed rules define exactly who may issue, offer, and sell payment stablecoins in the U.S., and separate regulators including the Federal Reserve and FDIC are working through their own versions under the same law. Meanwhile, infrastructure is being built out in parallel: Wyoming recently migrated its state-backed stablecoin’s cross-chain infrastructure to a new provider, and major card networks and cloud providers have begun treating agent-initiated stablecoin payments as something that needs dedicated infrastructure, a trend connected to the broader shift toward AI-driven commerce we described in how blockchain is used beyond cryptocurrency. In other words, the plumbing for stablecoin payments is being built even as a top global standard-setter questions whether the asset class is ready for it.
How It Could Affect Businesses and Consumers
For banks, the BIS’s warning about funding costs is the most concrete near-term concern. If customers shift deposits into stablecoins, banks could lose a relatively cheap source of funding, which could tighten lending conditions and push borrowing costs higher for households and businesses. For businesses that already use stablecoins for cross-border payments, the regulatory clarity emerging from the GENIUS Act and similar frameworks in the EU, UK, and parts of Asia should reduce legal uncertainty, even if compliance requirements grow more demanding. For everyday consumers, the practical effect for now is limited: stablecoins remain far more common in trading, remittances, and business-to-business settlement than in day-to-day retail purchases, and de Cos’s comments suggest that gap is unlikely to close quickly.
Key Benefits and Opportunities
Despite the skepticism, regulatory clarity itself is a meaningful opportunity for the industry. Seven major economies, including the U.S., EU, UK, Singapore, Hong Kong, UAE, and Japan, now require full reserve backing, licensed issuers, and guaranteed redemption rights for stablecoins, treating them as regulated payment instruments rather than speculative crypto assets. That shift gives banks and payment companies the certainty needed to build stablecoins into core payment infrastructure. Cross-border payments are already showing real gains: a South Korean regional bank recently became the first in the country to deploy blockchain-based payment rails for import-export and startup clients, citing settlement times measured in seconds rather than days, a benefit consistent with what our earlier piece on what investors need to know about Bitcoin in 2026 noted about blockchain settlement speed more broadly.
Risks and Challenges
Beyond the interoperability and funding concerns the BIS raised, unresolved questions remain even within the frameworks already in place. The GENIUS Act bars licensed stablecoin issuers from paying interest or yield directly to holders, but the law is silent on distributors, meaning exchanges can still pay reward-like payments funded from reserve income without technically violating the statute. The American Bankers Association and dozens of state banking associations have asked Congress to close that gap, while the OCC’s own February 2026 proposal moves in that direction, leaving the issue unresolved as of this writing. De Cos also raised a longer-term concern about “digital dollarization,” the risk that heavy adoption of dollar-pegged stablecoins outside the United States could weaken other countries’ monetary policy effectiveness by reducing reliance on domestic currencies.
What Experts, Companies, or Regulators Are Saying
U.S. Treasury Secretary Scott Bessent has argued that stablecoins could reinforce the dollar’s international standing while generating trillions of dollars in additional demand for U.S. Treasury securities, a view de Cos partly acknowledged could lower government borrowing costs even as he warned it might raise costs elsewhere in the banking system. The BIS did not rule out a larger future role for stablecoins, with de Cos saying they could become more relevant if issuers improve redeemability, cross-chain interoperability, and compliance controls over time. Regulators, for their part, appear to be converging on the view that non-bank issuers should face tighter restrictions on activities like lending and custody than banks already operating under prudential supervision.
What Happens Next?
The regulatory calendar over the next several months is dense. The OCC’s version of the GENIUS Act rules is due by November 2026, the broader issuance ban for unlicensed stablecoin issuers takes effect in January 2027, and a further cutoff for coins from unlicensed issuers follows in July 2028. Expect continued lobbying over the yield and rewards loophole, further international coordination as the EU’s MiCA framework matures alongside the U.S. rules, and more scrutiny of how non-bank issuers structure their broader corporate activities as regulators push toward group-wide supervision.
Conclusion
Stablecoins have moved from a crypto-market curiosity to a genuine subject of central bank concern in the space of a few years, and that shift alone says something about how seriously regulators now take them. The BIS’s message is not that stablecoins have no future in payments, but that the technology and oversight have not yet caught up to the ambitions building around them. With U.S. rules landing in stages through 2028 and global standard-setters still debating the basics of interoperability and bank funding risk, the honest answer for now is that stablecoins are being built into the financial system faster than anyone has finished deciding how safe that system will be as a result.
