1. They should be authentic leaders, focused on serving their clients and all the institution's constituents, rather than charismatic leaders seeking money, fame, and power for themselves.
2. They should place the interests of their institutions and society as a whole above their own interests.
3. They should have the integrity to tell the whole truth, admit their mistakes, and acknowledge their shortcomings. Authentic leadership is not about being perfect. It is having the courage to admit when you're wrong and to get on with solving problems, rather than covering them up.
4. They need to adapt quickly to new realities, changing themselves as well as their institutions, rather than going into denial when things don't go as intended.
5. They need the resilience to bounce back after devastating losses. Resilience enables leaders to restore trust by empowering people to create new solutions that build great institutions for the future.
Some of these leaders have already emerged on Wall Street. The short list includes JPMorgan's Jamie Dimon, Wells Fargo's Dick Kovacevich, Goldman's Lloyd Blankfein, and Morgan Stanley's John Mack. Their firms participated in the same markets as did the failed firms, and used similar financial instruments.
What's the difference? They kept their clients' interests paramount, took a more prudent approach to risk and leverage, kept their accounting conservative and transparent, and focused on long-term sustainability.
This short list is insufficient. What's required is a new generation of authentic leaders to step up to leading America's financial institutions. These new leaders must be committed to shifting away from short termism to focus on long-term results for their clients and their firms and to ensure sound, enduring capital markets for our country.
Only then can the financial community regain vitally needed trust and confidence of the American people. And only then can we be assured that we won't be back in a similar mess in a few years.
