BIS warns cryptocurrency exchanges are becoming ‘shadow banks,’ and why that's a risk

The Bank for International Settlements released a 38‑page report (Apr 23, 2026) warning that crypto exchanges’ “earn” and stablecoin yield products function like unsecured, bank‑like deposits without deposit insurance, transparency or traditional safeguards. The BIS cited past failures (Celsius, FTX) and the Oct 2025 flash crash — which forced about $19 billion in liquidations — to argue that leverage and opacity at large crypto platforms leave retail users exposed to solvency risk. The report frames major exchanges as evolving into multifunctional intermediaries that pool customer assets into lending, trading and market‑making activities. Market impact: heightened regulatory risk and negative sentiment for crypto yield products and intermediaries, potential for stricter oversight that could compress high‑yield offerings and increase counterparty scrutiny across crypto markets.
