The Yield Ban Paradox: $1-3T Flowing Into DeFi's Undefended Exploits

The stablecoin yield compromise bans passive income on centralized platforms, forcing $1-3 trillion into DeFi protocols where known 2022 vulnerabilities remain unpatched. Meanwhile, AI-powered fraud is surging 500%, creating dual-vector attacks that regulators may have inadvertently designed.

The yield ban pushes capital into the exact protocols where known 3-year-old vulnerabilities remain unpatched -- regulators are creating forced migration into a broken destination

AI-powered fraud 500% surge (prompt injection, algorithmic resonance)→DeFi capital migration from CeFi yield products

AI agents managing DeFi positions create new attack surfaces (prompt injection, key exposure) precisely as regulation forces more capital into AI-managed DeFi strategies

The OCC interpretation width is the single variable determining whether capital stays in regulated CeFi or floods into unregulated DeFi -- narrow = migration, broad = containment
