The World’s Central Bank Warns Stablecoins Could Break the Global Financial System

TLDR

• The Bank for International Settlements (BIS) says stablecoins fail to meet basic requirements for sound money
• The stablecoin market is worth around $316–320 billion, with USDT and USDC dominating
• BIS warns of “stablecoin dollarization” threatening monetary sovereignty in emerging economies
• Public blockchains like Bitcoin and Ethereum are criticized for lacking governance and scalability
• BIS pushes a “unified ledger” model using tokenized central bank and commercial bank money as the safer path forward

The BIS, which acts as a central bank for central banks, released its Annual Economic Report on Sunday, June 28, 2026. The report takes a hard look at the growing stablecoin market and raises serious concerns about where it is heading.

Stablecoins Fall Short on the Basics

The BIS says stablecoins do not meet four key standards for money: singleness, elasticity, interoperability, and integrity. The report argues today’s dollar-pegged tokens behave more like exchange-traded fund shares than actual money.

Stablecoin prices sometimes drift from their pegs in open markets. Redemptions can involve friction and delays, which the BIS says makes them unreliable as a payment tool.

The total stablecoin market sits at around $320 billion. More than 99% of fiat-backed supply is pegged to the US dollar, and most of that is split between Tether and Circle’s products.

BIS modeled what would happen if stablecoins grew to $1 trillion, $2 trillion, or even $3 trillion in value. In each scenario, the net effect on economic output was slightly negative. Higher bank funding costs and weaker lending offset any gains.

The report also flags stablecoins as a channel for illicit activity. Because they run on permissionless blockchains where pseudonymity is common, anti-money-laundering checks are harder to enforce.

The Risk to Emerging Economies

The BIS reserved some of its sharpest warnings for developing countries. It describes a trend it calls “stablecoin dollarization,” where people in countries with weaker currencies shift into dollar-pegged tokens.

This could reduce the effectiveness of local monetary policy. It could also pull bank deposits out of the domestic system, cut credit availability, and expose those economies to sudden cross-border capital flows.

Public Blockchains Under Pressure

The report also takes aim at public permissionless blockchains, including Bitcoin and Ethereum. BIS argues these networks struggle to meet the standards needed for large-scale financial infrastructure.

The core issue is how these networks handle rising demand. As activity increases, fees go up and confirmation times get longer. BIS says this is a structural feature, not a bug that can be patched.

Without clear governance or an identifiable body responsible for compliance and dispute resolution, BIS argues these networks cannot reliably support regulated financial activity.

A Different Path Forward

Rather than calling for a ban, BIS is pushing an alternative model. It wants to see a “unified ledger” that combines tokenized central bank money, tokenized commercial bank deposits, and other regulated assets on a single programmable platform.

The BIS pointed to Project Agora, a cross-border payments prototype involving eight central banks and over 40 private institutions, as proof this model can work.

The BIS says this approach keeps the benefits of fast, programmable payments while preserving financial stability and public trust in money.
