The 25% threshold creates a structurally hollow equilibrium

Under the Missing System Theorem, the bilateral game between regulators and institutions excludes system welfare. The threshold produces a Hollow Win: institutions pass exams, regulators report coverage, but criminal actors exploit the gap.

• Beneficial Ownership Invisibility Theorem: any threshold T>0 creates an arbitrage class
• FinCEN data: entities with 20-24% ownership are 3.4x more likely to be associated with SARs
• β_W = 0.083: each dollar of banking revenue destroys $0.083 of system welfare

The bilateral game excludes system welfare

The US CDD Rule structures a game between regulators and financial institutions that ignores the financial system's integrity. Both sides win on their own metrics, but the system degrades.

• Regulators aim for coverage; institutions aim for compliance at lowest cost
• Neither party is incentivized to close the loophole
• Result: a (1,1) equilibrium with system welfare at 0

Any positive threshold creates an invisible ownership class

The Beneficial Ownership Invisibility Theorem proves constructively that for any threshold T>0, criminals can structure ownership below T to avoid disclosure while maintaining effective control.

• Formal proof under axioms A1-A4
• Threshold acts as a bright line for evasion
• No disclosure reform within threshold structure can fix it (Disclosure Futility Theorem)

Ownership clusters just below 25% and links to suspicious activity

Analysis of FinCEN data from 2018-2023 shows systematic clustering of ownership in the 20-24% range. These entities are 3.4 times more likely to be associated with suspicious activity reports.

• Clustering indicates strategic avoidance of disclosure
• 3.4x SAR likelihood vs. entities above 25%
• Data covers 5 years of CDD filings

The threshold costs $60 billion annually in US welfare

The authors estimate β_W = 0.083 for the US AML system, meaning each dollar of banking industry revenue destroys 0.083 of system welfare through facilitated criminal activity. Total annual welfare loss: 60 billion.

• β_W = 0.083 derived from FinCEN and industry data
• $60 billion = welfare loss from the threshold alone
• Includes costs of crime, enforcement, and lost trust

€200 billion non-resident portfolio exploited the threshold

Danske Bank's Estonian branch processed €200 billion from non-resident customers. Ownership was fragmented below 25% to avoid CDD scrutiny, enabling large-scale money laundering.

• Non-resident portfolio grew rapidly with minimal beneficial ownership checks
• Fragmented ownership structures below 25%
• Scandal revealed after whistleblower; bank fined heavily

Offshore law firms systematically used sub-threshold ownership

The Panama Papers leak showed Mossack Fonseca creating shell companies with ownership split below 25% to avoid disclosure. This allowed anonymous control while appearing compliant.

• Over 200,000 offshore entities created
• Many had multiple owners each below 25%
• Threshold enabled the entire business model

Threshold-free disclosure achieves 98.7% compliance

Norway replaced thresholds with continuous, threshold-free beneficial ownership identification. Result: 98.7% compliance and a 76% reduction in law enforcement requests for ownership data.

• All beneficial owners must be identified regardless of ownership percentage
• Central registry updated continuously
• Operationally feasible; low burden on businesses

Threshold-free disclosure enables a Win-Win-Win outcome

The Game Change Existence Theorem shows that replacing the threshold transforms the payoff space to include system welfare. The equilibrium shifts from (1,1,0) to (1,1,1) for regulators, institutions, and the system.

• Continuous disclosure removes the arbitrage class
• Institutions gain clarity and reduce reputational risk
• Regulators achieve genuine financial integrity

Replace the 25% threshold with continuous disclosure

The authors propose eliminating the 25% threshold and requiring identification of all beneficial owners. Estimated Reform Dividend: $60 billion annually for the US, based on welfare loss recovery.

• Adopt Norway's model: continuous, threshold-free registry
• No bright line for evasion
• Compliance cost offset by reduced crime and enforcement
