What the BIS 2026 report says about stablecoin risks

-


The Bank for International Settlements (BIS) used its 2026 Annual Economic Report to examine how stablecoins are being used and what wider risks could emerge if adoption grows.

The report recognises that stablecoins can support programmable and faster payments. Its central warning is that today's designs do not automatically provide the same trust, settlement finality or public safeguards as established monetary systems.

What the BIS data says

The BIS estimated total stablecoin market capitalisation at about USD 320 billion at the end of May 2026. It also cited estimated 2025 transaction volume of roughly USD 28 trillion.

Those figures need context. The report says crypto trading remains a major use case, while transfers between wallets controlled by the same party can inflate gross transaction figures. Fees, spreads and the cost of moving between bank money and stablecoins can also reduce the apparent advantage in cross-border payments.

Why reserve composition matters

Large fiat-backed stablecoins commonly hold short-dated government debt, cash, bank claims or reverse-repurchase positions. Reserve quality, liquidity, custody and redemption arrangements determine how an issuer might respond when many holders seek to redeem at once.

A token trading near one dollar during normal conditions does not prove that every holder can redeem immediately during stress. Users should check the issuing entity, redemption eligibility, reserve disclosures, audit or assurance scope, and the legal claim attached to the token.

The dollarisation concern

Most stablecoin value remains linked to the US dollar. The BIS argues that widespread foreign-currency stablecoin use could reinforce currency substitution in emerging and developing economies, alter capital flows and complicate monetary policy.

This is a scenario and policy risk, not a prediction that every country will experience digital dollarisation. The outcome depends on local inflation, financial access, regulation, user behaviour and the availability of trusted domestic payment alternatives.

What the report does not establish

  • It does not say every stablecoin has the same reserves or redemption risk.
  • It does not prove that reported transaction volume equals retail payment use.
  • It does not guarantee that regulated stablecoins cannot lose their peg.
  • It is not a recommendation to buy, sell or avoid a particular token.

Ethereum's 2026 roadmap: shipped upgrades versus future plans

-
Ethereum's roadmap changed substantially between 2024 and 2026. Dencun activated in March 2024, Pectra followed in May 2025, and Fusaka activated in December 2025. The next named upgrade is Glamsterdam—but users should distinguish completed upgrades from proposals and estimated dates. What has already happened Dencun introduced blob transactions that reduced the cost of posting rollup data. Pectra included changes such as EIP-7702, which allows externally owned accounts to delegate functionality to smart-contract code. Fusaka added further scaling and data-availability improvements. These are historical activations, not future promises. Their practical effects still depend on wallets, applications, network demand and how developers implement the new capabilities. What is planned next Ethereum.org identifies Glamsterdam as the next named upgrade. Block-level Access Lists and enshrined proposer-builder separation have been described as headline items, with an expected activation...

UK crypto regulation: what changes in October 2027

-
The United Kingdom created a broader cryptoasset regulatory framework in 2026, but the main new authorisation regime is not yet fully in force. HM Treasury says the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 will take effect in October 2027. That timing matters. A company saying it is “registered in the UK” today should not automatically be described as already authorised under the future regime. What the 2026 Regulations establish The Regulations bring specified cryptoasset activities into the UK's regulated-activities framework. When the relevant provisions commence, firms carrying on those activities will generally need authorisation from the Financial Conduct Authority (FCA), unless an exclusion or another applicable status applies. HM Treasury's April 2026 policy note says the framework was made in February 2026 and comes into force in October 2027. The government also proposed amendments dealing with stablecoin payment services and other t...

What the SEC's 2026 crypto interpretation actually says

-
On 17 March 2026, the US Securities and Exchange Commission issued an interpretation explaining how federal securities laws apply to several types of crypto assets and transactions. The Commodity Futures Trading Commission joined the interpretation with guidance on how its staff would administer the Commodity Exchange Act consistently with it. The headline is important but easy to oversimplify: the SEC said most crypto assets are not themselves securities. That does not mean every sale, distribution, staking service or investment arrangement involving a token falls outside securities law. What the interpretation covers The interpretation provides a taxonomy covering digital commodities, digital collectibles, digital tools, stablecoins and digital securities. It also addresses protocol mining, protocol staking, airdrops and the wrapping of non-security crypto assets. A central distinction is between an asset and the transaction or arrangement through which it is offered. A non-secur...
