BIS Says Stablecoins Resemble ETF-Like Assets, Not True Money

The Bank for International Settlements (BIS) has delivered one of its bluntest assessments yet of stablecoins, arguing they function less like ‘money’ and more like an ‘ETF-like asset’ whose value is tied to underlying reserves but remains subject to redemption frictions and market stress. The view, highlighted in a research summary by MEXC Ventures, lands as policymakers in the U.S. and Europe push stablecoins deeper into regulated finance—raising the stakes over how the market should be supervised as it scales.

In its 2026 Annual Economic Report, released around the BIS annual meeting on June 28 (UTC), the institution said stablecoins do not meet core requirements typically expected of money, including reliable ‘par convertibility’, elastic supply, seamless integration with the financial system, and robust safeguards against illicit use. The critique comes despite the sector’s size: stablecoin market capitalization stood near $320 billion as of late May 2026, with dollar-pegged tokens accounting for roughly 99.4% of the total, according to the figures cited by MEXC Ventures.

The timing is notable. The BIS—whose membership includes 63 central banks—issued its assessment as the U.S. moves to formalize federal oversight of private issuers under the 2025 ‘GENIUS Act’ and the European Union brings crypto-asset issuance and service providers under its MiCA framework. While investors and payments firms have increasingly framed stablecoins as a foundation for next-generation settlement rails, the BIS is signaling that growth alone does not confer monetary legitimacy.

The first and most pointed objection centers on ‘1-to-1 redeemability’. In traditional finance, cash and commercial bank deposits generally trade at par because both ultimately sit within a system backstopped by central bank money and prudential regulation. Stablecoins, by contrast, have repeatedly deviated from their intended peg during periods of market turbulence, with “$1” instruments trading at $0.98 or $0.95 not as rare anomalies but as recurring stress behaviors. The BIS pointed to the 2022 collapse of TerraUSD (UST) as a cautionary example of how peg drift can evolve from a liquidity event into a systemic design failure. MEXC Ventures said the report’s framing effectively treats stablecoins as financial products with ‘redemption frictions’ rather than cash-equivalent money.

The second issue is supply elasticity. Central banks expand liquidity during downturns and withdraw it in overheated conditions, using monetary tools to support macroeconomic stability. Stablecoin supply, however, expands and contracts mainly with inflows to reserve assets, redemption demand, or algorithmic mechanisms—none of which are designed to respond to broader economic conditions. Because issuance is driven by private entities rather than public-policy institutions, the BIS argued, stablecoins lack both the mandate and the mechanisms to adjust supply in line with economy-wide needs.

Third, the BIS challenged the narrative of frictionless transferability. Stablecoins may move quickly on-chain, but converting them into bank deposits or moving value across networks typically requires intermediaries such as exchanges, custodians, and settlement processes. Those steps introduce time delays, fees, and counterparty risk—features that look less like cash and more like investment instruments. The BIS’s comparison to ETFs rests on this gap: while ETFs track underlying assets, investors are not guaranteed instantaneous redemption at face value. Stablecoins may claim dollar equivalence, the BIS argued, but their off-chain and cross-platform realities can prevent truly immediate, par-value conversion.

A fourth vulnerability lies in financial integrity controls. The BIS emphasized that functional money is not merely a medium of exchange; it operates within an enforceable framework for oversight, identity checks, and sanctions compliance. Stablecoins used in cross-border transactions can still be structured in ways that weaken ‘AML’ and ‘KYC’ safeguards or enable sanctions evasion, the report said, particularly when regulatory rules differ widely across jurisdictions. With digital assets moving easily across borders, the BIS warned, ‘regulatory arbitrage’ can rapidly open supervision gaps.

The report placed particular emphasis on emerging markets, where stablecoins could behave like a de facto substitute currency. In economies facing sharp currency volatility or limited banking access, dollar-linked stablecoins can appear to users as a rational hedge and a practical payment tool. But at the national level, wider stablecoin adoption could erode ‘monetary sovereignty’ and reduce the effectiveness of interest-rate policy and liquidity management. If households and businesses increasingly save and transact in dollar-based tokens, central bank actions may transmit more weakly into the real economy.

Beyond monetary policy, the BIS also underscored potential knock-on effects for banks. Even if stablecoins grew to $1 trillion to $3 trillion in market value, the report suggested the direct impact on global output might remain limited. The more sensitive channel, it argued, could be deposit flight: as funds move from bank deposits into stablecoins, banks’ funding bases could weaken, potentially constraining credit creation. In that sense, the BIS framed the core risk as less about payment innovation and more about the potential ‘weakening of credit intermediation’.

As an alternative path, the BIS promoted the concept of a ‘Unified Ledger’—an architecture that links central bank digital currency, commercial bank deposits, and tokenized real-world assets within a single platform while keeping central bank money as the ultimate trust anchor. The approach does not exclude private-sector innovation, but it re-centers settlement finality and system integrity on central bank liabilities. The BIS pointed to ‘Project Agora’ as an early test case: an international experiment involving eight central banks and more than 40 private financial institutions exploring how to improve the speed and efficiency of large-value cross-border payments.

Market participants are unlikely to read the report as a blanket rejection of stablecoins. Instead, the BIS appears to be drawing a line between demand for digital settlement instruments and the claim that today’s dominant structures qualify as money. That distinction may shape the next phase of policy: tighter requirements around reserve transparency, enforceable redemption rights, stronger AML/KYC controls, and more direct connectivity to regulated payment infrastructure.

The central message, as MEXC Ventures distilled it, is that stablecoins’ rapid expansion does not automatically grant them the public-good qualities associated with sovereign money. For now, the BIS argues, they resemble financial products that track the dollar while retaining structural market frictions. The next test will be whether issuers can resolve those weaknesses through technology and regulation—and whether central bank-centered models like the Unified Ledger can set the standard for global settlement in an increasingly tokenized economy.
