Summary

American banker and CEO of JPMorgan Chase since 2005, widely regarded as the most capable banker of his generation for navigating the 2008 financial crisis and building the world's most profitable bank.

Core Contribution

Built JPMorgan's 'fortress balance sheet' discipline — maintaining excess capital and liquidity as a competitive weapon rather than a drag — and used it to acquire Bear Stearns and Washington Mutual at distressed prices during 2008, emerging stronger from the crisis than any competitor.

Key Spikes & Highlights

  • Fortress Balance Sheet as Offensive Weapon (maintains excess capital not as safety buffer but as the capacity to act aggressively when competitors are distressed — treated the 2008 crisis as the payoff for years of unpopular conservatism)
  • Blunt Diagnosis Over Diplomatic Management (JPMorgan's annual letters explicitly name risks — geopolitical, regulatory, competitive — that peer CEOs would never document publicly, treating candor as an institutional discipline)
