BIS warns crypto exchanges become shadow banks

TLDR

The Bank for International Settlements (BIS) is warning that major crypto exchanges increasingly behave like lightly regulated shadow banks, creating unsecured lending and systemic risk.

1. BIS says earn and yield products on big exchanges function like unsecured loans, citing Celsius, FTX and recent liquidation cascades as evidence of shadow banking style risk.
2. Users who think they hold deposits actually hold unsecured claims on leveraged, opaque intermediaries with no deposit insurance or capital rules, which can amplify crashes.
3. Regulators are likely to tighten rules on yield products and exchange balance sheets, while institutions gravitate to models with segregated custody and stricter oversight.

Deep Dive

1. What BIS Is Warning About

BIS argues that many cryptoasset service providers, including large exchanges, now offer earn and yield products that closely resemble bank deposits but lack basic banking safeguards. In its recent report, it describes these offerings as unsecured loans to the platform, where customer assets are pooled and deployed into lending, trading and market making without deposit insurance, capital buffers or clear resolution regimes, effectively forming a lightly regulated shadow banking sector built on crypto. The report highlights that some firms bundle exchange, brokerage and lending functions into multifunction cryptoasset intermediaries, blurring lines that would normally be separated in traditional finance and increasing single point of failure risk.

2. How This Risks Users And Markets

From the customers perspective, BIS stresses that these products are unsecured claims on the platform, so in a failure they sit behind secured creditors, as seen in the collapses of Celsius and FTX where users became bankruptcy creditors. It also links shadow banking style leverage to market instability, pointing to an October 2025 flash crash where about 19 billion dollars in leveraged positions were forcibly liquidated in 24 hours, Bitcoin fell over 14 percent in a day, and roughly 350 billion dollars was wiped from total crypto market value. Because a few large venues combine high leverage, automated liquidation engines and thin liquidity in key pairs, stress on one exchange can rapidly propagate into wider market turmoil.

3. What To Expect From Regulation And Venues

BIS suggests regulators should treat many yield products as securities or loans, with registration, risk disclosures and prudential-style requirements closer to bank standards. This aligns with moves like Europes MiCA regime and various enforcement and rulemaking efforts in the United States that target interest-bearing stablecoins and exchange earn programs. On the industry side, some exchanges are already experimenting with safer structures, such as off-exchange settlement with qualified custodians and clearer segregation between trading and custody, to appeal to institutions concerned about counterparty risk. For users, the practical signal is to watch whether platforms separate custody from risk-taking activities and how regulators in your jurisdiction choose to classify and constrain yield products.

Conclusion

BIS is effectively saying that parts of centralized crypto now look like a parallel banking system built without banking-style protections, and that this mix of unsecured lending and leverage can magnify shocks. As regulators respond and institutions demand stronger safeguards, exchanges that move toward transparent, segregated and lower-risk models are likely to gain trust, while lightly regulated, high-yield platforms face growing scrutiny and potential disruption.
