Back in September, chaos erupted in short-term funding markets, as the cost for financial institutions to borrow reserves soared. Immediately a major debate broke out over whether this represented a systemic problem for the financial system or merely a technical problem with the "plumbing." Things have quieted down since September, but the debate hasn't stopped. And there's still no permanent fix. On this week's Odd Lots podcast, we spoke with Zoltan Pozsar of Credit Suisse, who has a reputation for understanding the mechanics of these funding markets better than anyone else in the world. He broke down what really happened, and why we could see more craziness as soon as next month.
