Stablecoins and ETFs Risk: BIS Says $320B Market Isn’t Real Money

The Bank for International Settlements has a pointed message for anyone who thinks a dollar-pegged token is the same as a dollar: it isn’t. In its Annual Economic Report 2026, published June 29, the BIS makes the case that stablecoins carry far more structural resemblance to exchange-traded funds than to genuine money — and that the stablecoins and ETFs risk comparison is no mere academic footnote. It has real consequences for currency markets, emerging economies, and the growing regulatory effort to bring crypto in line with traditional finance.

Key takeaways

• The BIS classifies stablecoins as closer to ETFs than true money, citing price deviations from par and redemption frictions.
• The total stablecoin market stood at roughly $320 billion at end of May 2026, with more than 99% pegged to the U.S. dollar and dominated by Tether’s USDT and Circle’s USDC.
• Rising flows from non-dollar currencies into US dollar-pegged stablecoins are weakening domestic currencies and raising FX swap market costs.
• Stablecoin transfers do not settle on central bank balance sheets, distinguishing them fundamentally from bank deposits.
• Capital controls effective for traditional deposits are less effective against stablecoins due to their digital bearer nature and unhosted wallets.

BIS Classifies Stablecoins as More Similar to ETFs Than Money

The hallmark of true money, the BIS report argues, is that it is accepted as a means of payment “with no questions asked.” When someone pays with dollars — whether a physical bill or a bank deposit — nobody questions its value or legitimacy. It is expected to be worth exactly its face value at any moment. Stablecoins do not fully meet that standard, and the report is unambiguous about why.

Stablecoins’ price deviations and redemption frictions

Secondary-market prices of tokenized fiat currencies deviate from their pegged par value — not always dramatically, but enough to matter. That behavior mirrors how an ETF trades at a slight premium or discount to its net asset value. And just as ETF redemptions can involve delays or costs depending on fund structure, stablecoin redemptions are not as smooth as widely assumed. Converting a stablecoin back to cash does not guarantee an instant, guaranteed exchange at par value.

That friction is structural, not incidental. The BIS report frames current stablecoin designs as resembling ETF shares more than means of payment — a characterization that BIS General Manager Pablo Hernández de Cos had already floated in April, and which the Annual Economic Report now formalizes with supporting analysis.

Key differences from true money

The distinctions go deeper than price wobbles. Stablecoin transfers settle neither directly nor indirectly on central bank balance sheets, unlike bank deposits, which ultimately carry a guaranteed claim on central bank money. A stablecoin’s value is determined by the market’s confidence in the issuer’s reserves and redemption mechanism — not by any direct anchor to the monetary system.

The BIS also flags a failure in the cash-in-advance model. Under that model, an issuer would mint a new token only after a user deposits the equivalent cash — 100% pre-funding. Stablecoins don’t work that way, which means issuers cannot expand supply flexibly the way commercial banks do when extending credit. The report judges current designs as falling short on four foundational monetary properties: singleness, elasticity, interoperability, and integrity.

That is a sweeping indictment, especially as stablecoins are increasingly positioned in policy debates as legitimate payment infrastructure. A $320 billion market — with over 99% of supply dollar-pegged and most of it split between USDT and USDC — is no longer a niche. But size, the BIS implies, does not equal monetary legitimacy.

Stablecoins’ Impact on Foreign Exchange Markets and Dollarization

Crypto was supposed to offer an alternative to dollar dominance. Stablecoins are producing the opposite effect, and the BIS is paying close attention to where the flows are going.

Flows from non-dollar currencies into US dollar-pegged stablecoins

The report identifies rising flows from non-dollar currencies into US dollar-pegged stablecoins, a trend with measurable consequences. In spot markets, these flows can weaken domestic currencies. They also expose friction in arbitrage between crypto markets and conventional foreign exchange markets, and may raise the cost of accessing dollars through FX swap markets — effectively making dollar liquidity more expensive for everyone else.

Consequences for domestic currencies and FX market costs

The BIS frames this as a faster, harder-to-contain version of deposit dollarization — the well-documented phenomenon where households in economically stressed countries shift savings into foreign-currency bank accounts. The same macro triggers apply: high inflation and sovereign stress push people toward dollar-denominated assets. The difference is speed and reach. Stablecoin dollarization can happen through a phone app without any bank intermediary, and once it takes hold, the BIS warns, it tends to persist for years.

The economic modeling in the report adds another dimension. Even if stablecoins grew to $1 trillion, $2 trillion, or $3 trillion in market value, the BIS projects the net effect on economic output would turn slightly negative over the medium term. Higher bank funding costs and weaker lending capacity would outweigh the fiscal benefit from stablecoin demand for government debt. It is a sobering conclusion for proponents who argue that stablecoin adoption is unambiguously good for financial inclusion and growth.

Challenges in Regulating Cross-Border Stablecoin Use

Recognizing a problem and solving it are two different things. The BIS report is candid that regulators face a structurally different enforcement environment with stablecoins compared to traditional financial instruments.

Digital bearer nature and unhosted wallets complicate enforcement

Several countries, particularly emerging market and developing economies, have already moved to restrict cross-border stablecoin use. But the BIS notes those measures are likely to remain imperfect. The reason is fundamental: stablecoins function like digital bearer instruments. Possession is control. Combined with the availability of unhosted wallets — self-custodied accounts with no intermediary to compel compliance — cross-border movement of value becomes extremely difficult to monitor or intercept.

The report also highlights that stablecoins account for a significant share of illicit on-chain activity precisely because permissionless blockchains weaken the know-your-customer and anti-money-laundering checks that traditional finance relies on. That is a systemic integrity concern that price stability and reserve backing cannot fix on their own.

Limitations of capital controls on stablecoins

Capital controls work reasonably well on traditional bank deposits because banks are regulated entities subject to national jurisdiction. That leverage disappears with a self-custodied, borderless token. Restrictions designed for the banking system do not translate cleanly to stablecoins, leaving regulators with tools calibrated for a different era of capital movement.

The BIS does not leave the question entirely open-ended. As it did in 2025, the report proposes a “unified ledger” model — a shared venue holding tokenized central bank reserves, tokenized commercial bank money, and other regulated private money, with central bank money as the anchor. It pointed to Project Agora, a cross-border payments prototype involving eight central banks, the BIS itself, and more than 40 private institutions, as evidence the model is operationally viable. The implication is clear: innovation in digital money is welcome, but only if it stays connected to the institutional foundations that make money trustworthy in the first place.

Whether that vision gains traction in an environment where $320 billion in stablecoin supply already circulates outside those foundations is a question regulators and central banks will be wrestling with long after this report is filed away.

FAQ

Why does BIS consider stablecoins more like ETFs than money?

Because stablecoins often trade at prices that deviate from their pegged value and carry redemption frictions similar to ETF shares. Unlike true money, which is accepted at par with no questions asked, stablecoins depend on market confidence in the issuer’s reserves and redemption mechanisms — and their transfers do not settle on central bank balance sheets.

How do stablecoins affect foreign exchange markets?

US dollar-pegged stablecoins attract flows from non-dollar currencies, which can weaken domestic currencies in spot markets and increase costs in FX swap markets. The BIS describes this as a fast-moving form of dollarization that, once established, tends to persist for years.

What enforcement challenges do stablecoins pose for regulators?

Their digital bearer-like nature and the availability of unhosted, self-custodied wallets make traditional capital controls far less effective. Measures that work on bank deposits cannot be applied cleanly to borderless tokens, leaving significant gaps in cross-border enforcement.
