I doubt a week has gone by since last summer during which I haven't seen some pundit or other trot out Walter Bagehot's dictum that in the event of a credit crunch, the central bank should lend freely at a penalty rate. More often than not, this is contrasted with the actions of the Federal Reserve, which seems to be lending freely at very low interest rates.
Ben Bernanke, in a speech today, addressed this criticism directly:
What are the terms at which the central bank should lend freely? Bagehot argues that "these loans should only be made at a very high rate of interest". Some modern commentators have rationalized Bagehot's dictum to lend at a high or "penalty" rate as a way to mitigate moral hazard--that is, to help maintain incentives for private-sector banks to provide for adequate liquidity in advance of any crisis. I will return to the issue of moral hazard later. But it is worth pointing out briefly that, in fact, the risk of moral hazard did not appear to be Bagehot's principal motivation for recommending a high rate; rather, he saw it as a tool to dissuade unnecessary borrowing and thus to help protect the Bank of England's own finite store of liquid assets. Today, potential limitations on the central bank's lending capacity are not nearly so pressing an issue as in Bagehot's time, when the central bank's ability to provide liquidity was far more tenuous.
I'm no expert on Walter Bagehot, and in fact I admit I've never read Lombard Street. But I'll trust in Bernanke as an economic historian on this one, unless and until someone else makes a persuasive case that Bagehot's penalty rate really was designed to punish the feckless rather than just to preserve the Bank of England's limited liquidity."
I believe that the implicit and explicit government guarantees is the main reason that this crisis played out. From my perspective, the fall of Lehman showed this. The avalanche only began when the government failed to act, and investors and bankers thought that they might be on their own.
By the way, I've been collecting stories where people admit that they were counting on government guarantees. At some point, I might collect them together.
Here's one example:
http://www.nytimes.com/2008/10/23/business/economy/23paulson.html?_r=1&pagewanted=2&hp&oref=slogin
"Lehman officials said they believed the firm had not one but two potential buyers: Bank of America and Barclays, the big British bank. But both had conditions. Bank of America wanted the Fed to make a $65 billion loan to cover any exposure to Lehman’s bad assets, according to one person privy to the discussions who did not want to be identified because of their sensitive nature. Although this was more than double what the Fed had made available to facilitate the takeover of Bear Stearns by JPMorgan, Bank of America justified the request on the grounds that Lehman was larger.
Barclays also wanted a guarantee to protect against losses should Lehman’s business worsen before Barclays could compete its takeover."
Correct me if I'm wrong, but B of A and Barclays wanted government guarantees.
So it's not right to say that the were waiting for a bailout, but they did want government intervention and guarantees all along the way.
