BIS warns exchanges become crypto shadow banks

TLDR

The BIS is warning that many big crypto exchanges now operate like lightly regulated shadow banks, especially through high yield earn products.

1. A new BIS paper says exchanges that pool user deposits into lending and yield schemes are effectively acting as unsecured shadow banks without safeguards.
2. These products mimic bank deposits but lack deposit insurance, clear asset segregation, and capital rules, exposing users to Celsius and FTX style losses.
3. Regulators are likely to respond with tougher rules on yield products, reserve backing, and function separation, which could reshape how exchanges offer passive income.

Deep Dive

1. What The BIS Is Actually Saying

In its latest research, the Bank for International Settlements (BIS) argues that many cryptoasset service providers are forming a lightly regulated shadow crypto financial system. The paper highlights that major platforms such as Binance, Bybit, Coinbase, Crypto.com, MEXC, OKX and previously FTX offer lending and earn products that look like deposits but function as unsecured loans to the platform itself, according to a summary of BIS Occasional Paper 27 in a market report.

A separate analysis notes that exchanges have evolved into multifunction cryptoasset intermediaries that combine roles of banks, brokers and trading venues while remaining outside full bank regulation, as described in a recent overview.

2. Why This Is A Risk For Users And Markets

According to the BIS, high yield earn and staking like products are marketed as passive income but actually pool user assets into leveraged trading, lending and market making. From a legal and economic perspective, users hold only an unsecured claim on the platform rather than a protected deposit, a point emphasized in multiple summaries of the report such as this crypto market analysis.

When platforms fail or face a liquidity shock, there is no deposit insurance, no central bank backstop, and often weak segregation between client assets and house trading. The BIS points to Celsius and FTX collapses and an October 2025 liquidation cascade of roughly 19 to 20 billion dollars as concrete examples of how hidden leverage and opacity can translate into large, sudden losses.

3. How Regulation And Business Models Could Change

The BIS does not ban these services, but it strongly hints that they should be regulated more like traditional credit and investment products. That could mean treating earn offerings as securities or loans, imposing capital and liquidity rules, tightening disclosures, or forcing clearer separation between exchange, brokerage and lending functions.

Jurisdictions already moving on stablecoins and service providers, such as under the EUs MiCA regime, provide early templates, and BIS officials are explicitly calling for coordinated global standards to avoid regulatory arbitrage. For exchanges, that likely means slower rollout and more conservative design of yield products, and for users, more standardized risk disclosures and possibly lower but safer yields.

Conclusion

BIS is effectively saying that parts of centralized crypto now walk and talk like banking, but without banking grade safeguards. If regulators follow through, the biggest changes for users will be around how custodial yield products are structured, disclosed and limited, and the safest posture is to treat any promised return as coming with real, platform level risk.
