Competition, Banking, and Consumer Finance: Open Markets, Safe Money, and Exit

Aggressive antitrust can punish scale, deter investment, and make merger outcomes depend on agency ideology. Open interfaces widen attack surfaces. Credit caps can push desperate borrowers toward illegal markets. A public fallback may crowd out community institutions. These objections justify rebuttable presumptions, judicial review, technical security standards, plural providers, safer small-dollar supply, and outcome audits. They also identify the test: policy should increase entry, switching, service quality, and resilience while monitoring fraud and credit access. The compact holds because concentrated gatekeeping and distress-based revenue are measurable market failures that ordinary shopping cannot cure.

Large incumbents face litigation, interface, switching, and possible divestiture costs. Banks and fintech firms finance security, fraud response, basic accounts, and risk-based insurance premiums. High-cost lenders lose products that depend on repeated refinancing or prices above the national boundary. Taxpayers fund the fallback and enforcement capacity, with recovery from provider fees and penalties where appropriate. Consumers accept strong identity checks for high-risk actions. Proportional rules, technical assistance, safe-liquidity supply, and published cost recovery keep the compact from turning compliance into another barrier to entry.
