BIS Head Rejects Stablecoins as Viable Payments Instrument Amid Growing Institutional Adoption

At the Jackson Hole Economic Policy Symposium on August 28, Bank for International Settlements General Manager Agustín Carstens delivered a keynote that amounted to a formal rejection of stablecoins as a viable payments instrument. Speaking just hours after Federal Reserve Chair Kevin Warsh conspicuously avoided mentioning digital assets entirely, Carstens used a three-test framework, singleness, interoperability, and integrity, to argue that stablecoins fail every criterion that defines sound money.

The most intuitive test is the singleness test. In a functioning monetary system, one dollar is worth one dollar regardless of the institution holding it. However, if Ben holds USDT and Marie holds USDC, and a merchant accepts only one, the system fractures into parallel currencies with different acceptance and risk profiles.

According to Carstens, 'A stablecoin issued by a private entity is not the same as money issued by a central bank. It does not pass the test of singleness.' The interoperability test follows naturally, as central bank money settles across all participants in the system without friction. Stablecoins, by contrast, operate on fragmented rails with no universal settlement layer.

Carstens drew the sharpest line during the integrity test, stating that stablecoins carry counterparty risk of their issuer, reserve composition risk of their backing, and regulatory risk of an evolving framework. In contrast, central bank money carries an implicit guarantee of finality backed by sovereign authority.

The BIS has been advancing its position through its Innovation Hub's Project Agorá, which brings together seven central banks and major commercial banks to prototype cross-border tokenized deposit settlement. Carstens recommended tokenized deposits as the institutional alternative, claims on commercial banks represented on programmable rails, preserving the two-tier monetary structure while adding settlement speed and composability.

However, a consortium of twelve global heavyweights, including Bank of America, Wells Fargo, and Santander, is actively building a stablecoin venture on public chains. This directly competes with the BIS-endorsed tokenized deposit model. Fireblocks reports over $100 billion in monthly stablecoin volume, growing 300% year-over-year.

Carstens acknowledged that stablecoins and tokenized deposits will likely coexist in the near term but framed the distinction as fundamental: one is a private instrument that replicates some functions of money; the other is an extension of the existing monetary system with institutional guarantees intact.
