The Private-Money View of Financial Crises Gary Gorton, Yale and NBER
Financial Crises Doug Diamond: Financial crises are everywhere and always due to problems of short-term debt (and to the reasons why short-term debt is needed). Need short-term debt but vulnerable to runs. Challenge for theory: Explain the optimality of debt, even though it is vulnerable to runs.
Themes The evolution of money forms and how the information environment evolved. The price system is not supposed to work for bank money. When the price system works financial crisis. A crisis is an information event.
Crises are Systemic--1837 At the present moment [during the Panic of 1837], all the Banks in the United States are bankrupt; and, not only they, but all the Insurance Companies, all the Railroad Companies, all the Canal Companies, all the City Governments, all the Country Governments, all the State Governments, the General Government, and a great number of people. This is literally true. The only legal tender is gold and silver. Whoever cannot pay, on demand, in the authorized coin of the country, a debt actually due, is, in point of fact, bankrupt: although he may be at the very moment in possession of immense wealth, and although, on the winding up of his affairs, he may be shown to be worth millions. Gouge (1837; italics in original)
What is a financial crisis? A financial crisis is not just a bad event. Stock market crashes are not systemic events. A financial crisis is an event in which households or firms no longer believe that bank debt (money) is worth par instead the want cash: A run on the banks. Sudden but not irrational. But, banks do not have the cash, so insolvent. The banking system is insolvent.
Geithner: Of the twenty-five largest financial institutions at the start of 2008, thirteen failed (Lehman, WaMu), received government help to avoid failure (Fannie, Freddie, AIG, Citi, BofA), merged to avoid failure (Countryside, Bear, Merrill, Wachovia), or transformed their business structure to avoid failure (Morgan Stanley, Goldman). Bernanke s FCIC testimony--during September and October 2008... of the 13 the most important financial institutions in the United States, 12 were at risk of failure within a period of a week or two.
Financial Crises are not Rare Financial Crises: Have occurred in all market economies throughout history; Occur in advanced economies; Occur in emerging markets; Occur in economies with or without central banks; Occur with different forms of bank debt.
Financial Crises not Rare Since 1970 there have been 147 systemic events around the world. Occur in all market economies. Not just events from an earlier era. And not just in emerging markets. Of the 147 events, about 65% involved bank runs.

In the use of money, everyone is a trader; those whose habits and pursuits are little suited to explore the mechanism of trade are obliged to make use of money, and are no way qualified to ascertain the solidity of different banks whose paper is in circulation; accordingly we find that men living on limited incomes, women, laborers, and mechanics of all descriptions, are often severe sufferers by the failure of country banks...

Debt (cont.) Debt is information-insensitive. Does not mean riskless. Means that it is not profitable to produce private information. Avoids adverse selection. Price does not change much/at all. Price system not work.
Compare to Equity The value of equity always depends on the value of the backing assets or collateral. Producing information about equity is always valuable (if you are the only one producing it). Equity is information-sensitive.
Debt-on-Debt Debt backed by debt maximizes information-insensitivity. Free bank notes: backed by state bonds. Demand deposits: backed by loans to consumers and small businesses. Money market instruments: backed by debt. Repo: specific bond ABCP: asset-backed securities
Debt and Info Cut cash flows by seniority cuts information!! That s the point of debt.

Implications for Bond Prices Since bonds essentially are not traded after they have been sold, how are off-the-run bonds valued? The answer is that the value of a bond is estimated/guessed matrix pricing.
NASDAQ Most bonds are priced relative to a benchmark. This is where bond market pricing gets a little tricky. Different bond classifications, as we have defined them above, use different pricing benchmarks.
Bond Mutual Funds Look at how bonds held by different funds are marked-to-market. There is significant price dispersion across the exact same bonds (on average). The price dispersion is decreasing in bond credit quality: lower dispersion for higher rated bonds. Dispersion is higher for high yield bonds than for investment-grade bonds.
But, short-term debt is money Pre-crisis repo market ~ $10 trillion - Every morning more than $1 trillion rollover of tri-party repo in early 2008 - - Daily trading volume of bilateral repo $5.81 trillion in 2007 (SIFMA (2008)) - Non-rollover of repos caused bankruptcy of Bear Stearns and Lehman Bankruptcy Examiner s report (2010, p.3): - Lehman funded itself through the short term repo markets and had to borrow tens or hundreds of billions of dollars in those markets each day from counterparties to be able to open for business.

The Quiet Period, 1934-2007 A book called The End of History became a runaway best seller. Economists declared The Great Moderation. Bob Lucas announced that macroeconomics... has succeeded. Why no crisis? Moral hazard?
The Demand for Safe Assets There has always been a demand for safe assets. Historically, gold coins. Short-term safe debt money-like Long-term safe debt--- certainty of final payoff. Safe assets are debt that is near-riskless. Private sector cannot produce riskless debt. But, can produce substitutes: AAA/Aaa Abs.
The Transformation of the Financial System Over the last 30 years prior to the crisis, the architecture of the financial system changed. Immobile collateral bank loans became mobile collateral in the form of MBS and ABS can be traded, posted in derivative positions, collateral for repo and ABCP, rehypothecated.
