The world's most influential club of central banks has delivered a blunt verdict on stablecoins: they aren't really money. In its annual economic report, the Bank for International Settlements (BIS) — the Basel-based institution often called the "central bank for central banks" — argued that dollar-pegged stablecoins fail the core tests of sound money and could pose real dangers to weaker economies, The Block reported.

A quick primer: a stablecoin is a crypto token designed to hold a fixed value, almost always pegged one-to-one to the US dollar (the two biggest, USDT and USDC, dominate the market). They've exploded into a multi-hundred-billion-dollar business used for crypto trading, payments and cross-border transfers.

The three tests stablecoins flunk

The BIS judges any monetary system against three properties, and says stablecoins come up short on all three, in its 2026 report:

  • Singleness. A dollar should be worth a dollar, full stop, whoever issues it. The BIS argues stablecoins violate this because they can trade at slight discounts and carry friction when moving between issuers and blockchains — so "a dollar" isn't always exactly a dollar.
  • Elasticity. Real monetary systems can expand and contract the money supply as the economy needs — a central bank can lend freely in a crisis. Stablecoins are rigid: the supply only changes when people buy or sell them.
  • Integrity. Money should resist crime. The BIS points to stablecoins circulating on public blockchains with pseudonymous users and patchy identity checks, making them attractive for illicit use.

The warning to developing economies

The sharper warning is about emerging markets. In countries with high inflation or shaky institutions, citizens already reach for dollars. The BIS frets that if that demand pours into dollar stablecoins rather than the banking system, it could accelerate capital flight and erode monetary sovereignty — a government's ability to run its own currency and interest rates. Money would leak out of local banks (which use deposits to make loans) and into tokens beyond the central bank's reach — a digital twist on old-fashioned "dollarization."

The context — and the pushback

The timing is pointed. Stablecoins are being pulled into formal regulation worldwide: the US enacted its GENIUS Act stablecoin law in 2025, and the EU's MiCA rules are now in force — both requiring issuers to hold proper reserves and meet anti-money-laundering standards, which addresses some of the BIS's integrity concerns. Boursel has covered both.

The crypto industry pushes back hard, and not without cause. Stablecoins settle in seconds, around the clock, for pennies — far cheaper than bank wires — and have become a genuine lifeline for remittances and for savers in countries whose own currencies are crumbling. The argument, the industry says, isn't whether stablecoins are useful; it's whether they can be designed to sit safely alongside national money.

That is roughly where the BIS lands too. Rather than simply condemning the technology, it floats an alternative vision — a "unified ledger" that would put tokenized central-bank money and tightly regulated private tokens on shared infrastructure, keeping the innovation but anchoring it to central-bank backing. That remains a concept, not a system.

Why it matters

The report is significant less for any single number than for who is saying it. The BIS is the cautious, technocratic core of the global financial establishment, and its message is that the world's regulators should treat stablecoins as a potential risk to monetary stability, not just a payments novelty. As stablecoins move from crypto's fringe toward the financial mainstream — courted by banks, payment firms and now governments — that warning will shape how hard, and how fast, the rules tighten around them.
