Jeremy Barnum of JPMorgan warns about fake stable yields: ghost banks in blockchain costumes

JPMorgan’s Chief Financial Officer, Jeremy Barnum, has issued a direct warning against a new generation of stablecoin protocols promising attractive yields. These platforms — like Usual, ENA, and Unitas — adopt the same mechanisms as traditional banks but without adhering to their prudential constraints. Jeremy Barnum clearly describes this model as a “ghost bank disguised as a blockchain,” a dangerous paradox for sector stability.

Platforms that replicate the banking model without its safeguards

These high-yield stablecoins promise regular interest on deposits, enticing users with the promise of simple and attractive gains. However, unlike traditional banks, which have built their models over centuries of prudential regulation, these protocols deliberately circumvent essential standards. They operate in a regulatory gray area, exploiting the lack of a clearly defined legal framework for decentralized finance.

The critical absence of protection mechanisms

Jeremy Barnum emphasizes that these platforms lack two fundamental pillars: first, no capital adequacy ratio is required, unlike regulated banking institutions; second, no deposit guarantee protects users in case of a crisis. This double absence turns each user into an uninsured creditor, exposed to total loss if the platform collapses.

A building systemic instability

The real risk, according to Jeremy Barnum, lies in the gradual accumulation of these unsecured positions. If these protocols continue to attract massive capital, a cascading contagion could destabilize the entire crypto ecosystem. Financial authorities are now monitoring these innovations with justified suspicion, recognizing in these “ghost banks” a replay of the mistakes that preceded major financial crises in the past.
