BIS warns crypto exchanges mimic shadow banks

TLDR

The Bank for International Settlements (BIS) is warning that big crypto exchanges increasingly behave like shadow banks through high yield earn and lending products without banking style safeguards.

1. BIS says many large exchanges now bundle trading, lending, and yield products that function like unsecured deposits, but without capital buffers or deposit insurance.
2. The core risk is that users are effectively unsecured creditors to highly leveraged platforms, which could magnify losses and contagion in a severe crypto drawdown.
3. Regulators are likely to respond with bank-like rules for these products, so users should expect tighter limits on leverage, yield offers, and stronger disclosure requirements.

Deep Dive

1. What BIS Is Actually Warning About

In a new report, the BISs Financial Stability Institute says major centralized platforms such as Binance, Coinbase, Bybit, Crypto.com, Kraken, MEXC, and OKX now operate as multifunction crypto asset intermediaries that resemble banks in how they take and deploy customer funds, but lack banking protections. The report highlights that earn products like Binance Simple Earn or Bybit Easy Earn transfer asset ownership to the platform, with users holding only an unsecured claim on the exchange, similar to an uninsured deposit. According to the BIS, these platforms pool customer assets and use them for lending, market making, and DeFi strategies, while also offering high margin trading and derivatives, a concentration of roles that in traditional finance would be split across banks, brokers, and dealers. The warning is detailed in a BIS linked report and a companion earn products analysis.

2. Why This Creates User And Systemic Risk

Shadow banking usually means credit and maturity transformation outside the fully regulated banking system. BIS argues that many crypto earn accounts do exactly that, turning short term, withdrawable claims by users into longer dated or risky positions on the back end, but without capital requirements, liquidity buffers, or access to central bank funding. The report cites Celsius failure and an October 2025 flash crash with an estimated 19 billion dollars in forced liquidations as examples of how leverage and opaque rehypothecation can suddenly crystallize into large losses. Because terms of service often allow commingling and suspension of withdrawals, users can find themselves behind creditors in insolvency, which is very different from insured bank deposits.

3. What To Watch From Regulators And Platforms

The BIS notes that only a minority of surveyed jurisdictions currently have full frameworks for these crypto intermediaries, and most do not yet cover borrowing, lending, or earn products comprehensively. Its recommendations include prudential capital rules, stress testing, consolidated supervision across all services offered by a group, and coordinated cross border oversight for large stablecoin and exchange providers. In practice, that could translate into tighter leverage caps, clearer segregation of client assets, stricter disclosure on how earn funds are deployed, or reclassifying some products as securities or bank like deposits. For users, this likely means less aggressive yields but better clarity on who bears losses when markets seize up.

Conclusion

BIS is effectively saying that the biggest crypto trading platforms now sit closer to lightly regulated shadow banks than simple exchanges, because they take deposit like funds and redeploy them into risky, leveraged activities. If regulators follow its recommendations, the industry could see a shift toward lower headline yields and higher transparency, trading some upside for a more resilient structure around centralized earn and lending products.
