The Bank for International Settlements (BIS) has concluded that stablecoins still fail to meet the core requirements of money, citing persistent weaknesses in design and market structure. In its Annual Economic Report 2026, the BIS said these tokens do not reliably function as a means of payment or a unit of account, pointing to shortcomings in consistency, scalability, and trust.
The report argues that stablecoins struggle with âsingleness,â meaning they do not maintain uniform value across systems, while issues with elasticity and interoperability limit their usefulness in broader financial activity. Integrity concerns, including compliance and governance gaps, further weaken their role in global markets.
Limited economic impact despite growth
Even if adoption increases, the BIS expects stablecoins to have only a modest impact on global economic output. The report notes that any fiscal benefits tied to demand for government bonds could be offset by tighter bank funding conditions and reduced lending capacity.
As of May 2026, the stablecoin market was valued at roughly $320 billion, far below earlier projections of up to $3 trillion. More than 99% of fiat-backed stablecoins remain linked to the U.S. dollar, reinforcing the dominance of dollar-based digital assets.
Market concentration raises systemic concerns
The BIS highlights the heavy concentration within the sector, where USDT and USDC together account for more than 83% of total supply. This dominance creates structural risks, as instability in either token could ripple across the broader cryptocurrency ecosystem that depends on them for liquidity.
The report also finds that stablecoins frequently deviate from their intended pegs and rely on inconsistent redemption mechanisms. As a result, traders tend to treat them more like financial instruments than true money.
Risks tied to reserves and debt markets
The BIS draws a comparison between stablecoins and exchange-traded funds, arguing that their reliance on underlying reservesâoften government debtâcould introduce stress during periods of heavy redemptions. Large-scale withdrawals may force issuers to liquidate treasury holdings بسعؚ؊, potentially disrupting sovereign debt markets.
This framing reflects broader skepticism within the institution about whether privately issued tokens can scale safely without introducing new vulnerabilities into the financial system.
Dollarization pressures in emerging economies
The report warns that âstablecoin dollarizationâ could accelerate in developing economies, where households may shift savings into dollar-backed tokens. Such movement risks weakening domestic monetary control and reshaping local capital markets.
Authorities in these regions may respond with tighter regulations, including capital controls or restrictions on service providers, which could limit cross-border flows of digital assets.
Central banks push unified ledger alternative
In response, the BIS is advocating for a regulated framework that integrates tokenization under central bank oversight. Its proposed âunified ledgerâ would combine tokenized central bank reserves, commercial bank deposits, and regulated private money on a shared infrastructure.
This approach builds on Project Agora, a BIS-led initiative involving multiple central banks and private institutions. Early tests have shown that cross-border transactions using tokenized reserves can settle ×××˘× instantly, and the project is now moving toward real-value transactions.
Regulatory momentum builds globally
The BIS stance aligns with a broader push by regulators to define clear rules for stablecoins. Frameworks such as the European Unionâs MiCA and the United Statesâ GENIUS Act of 2025 already distinguish between regulated and unregulated issuers.
The report suggests that this divide will become increasingly important as authorities accelerate oversight efforts, shaping which digital assets are allowed to integrate into mainstream financial systems and which remain on the margins.
