According to the Bank for International Settlements, crypto exchanges, stablecoin yield products, and DeFi earn services are offering bank-like returns and credit exposure without deposit insurance, prudential oversight, or comparable safeguards.
The Bank for International Settlements warned that major cryptocurrency exchanges and crypto yield products increasingly resemble shadow banks by combining trading, custody, lending, and leverage with limited oversight. The report said exchange wealth-management and yield products, stablecoin yield offerings, and DeFi earn services can function like deposit, savings, or cash-management products while leaving users exposed as unsecured creditors without deposit insurance, liquidity backstops, or prudential safeguards. The BIS linked these risks to high leverage, opacity, weak customer protections, and a reported $19 billion wipeout in 2025, while also citing Celsius, FTX, and the October 2025 flash crash as examples of how stress can spread across digital asset markets.
