JPMorgan was already, for the most part. Our businesses at JPMorgan share the same cash-management systems. The commercial bank, the private bank, the retail bank, they all use the branches. The cash-management system moves the money around the world - for global corporations, and for you, the consumer, too.

Companies that grow for the sake of growth or that expand into areas outside their core business strategy often stumble. On the other hand, companies that build scale for the benefit of their customers and shareholders more often succeed over time.

Capping the size of American banks won't eliminate the needs of big businesses; it will force them to turn to foreign banks that won't face the same restrictions.

I haven't studied it deeply, but the American banks started the crisis with far more capital and what I would call "good liquidity." The riskiest funding is unsecured wholesale funding. It's the most fickle. Not repo, which the government focused on, too. Unsecured. JPMorgan Chase had almost none of that - virtually zero.

The economic union - creating a big common market, like the United States, so that you can compete across borders. There are common rules, regulations, and simplification, and that is still a good reason, too. When they put their monetary union together, that created a rigidity that made it hard for currency fluctuations. They don't really have a solution to that.

You don't run a business hoping you don't have a recession.

Not every company went bankrupt. Not every bank needed TARP [Troubled Asset Relief Program]. So I'm very proud that JPMorgan, throughout that time period, was completely steadfast. We bought Bear Stearns because we thought we were helping the situation. We didn't cut and run.
