Modern financial systems are inherently vulnerable. The conversion of savings into investment—a basic function of finance—involves substantial risk. Creditors often demand liquid, short-term, low-risk assets; and borrowers typically wish to finance projects that take time to generate their uncertain returns. Intermediaries that bridge this gap—transforming liquidity, maturity and credit between their assets and liabilities—are subject to runs should risk-averse savers come to doubt the market value of their assets.
The modern financial system is vulnerable in a myriad of other ways as well. For example, if hackers were to suddenly render a key identification technology untrustworthy, it could disable the payments system, bringing a broad swath of economic activity to an abrupt halt. Similarly, the financial infrastructure that implements most transactions—ranging from retail payments to the clearing and settlement of securities and derivatives trades—typically relies on a few enormous hubs that are irreplaceable in the short run. Economies of scale and scope mean that such financial market utilities (FMUs) make transactions cheap, but they also concentrate risk: even their temporary disruption could be catastrophic. (One of our worst nightmares is a cyber-attack that disables the computer and power grid on which our financial system and economy are built.)
With these concerns in mind, we welcome our friend Kathryn Judge’s innovative proposal for a financial “Guarantor of Last Resort”—or emergency guarantee authority (EGA)—as a mechanism for containing financial crises. In this post, we discuss the promise and the pitfalls of Judge’s proposal. Our conclusion is that an EGA would be an excellent tool for managing the fallout from dire threats originating outside the financial system—cyber-terrorism or outright war come to mind. In such circumstances, we see an EGA as a complement to existing conventional efforts at enhancing financial system resilience.
However, the potential for the industry to game an EGA, as well as the very real possibility that politicians will see it as a substitute for rigorous capital and liquidity requirements, make us cautious about its broader applicability. At least initially, this leads us to conclude that the bar for invoking an EGA should be set very high—higher than Judge suggests…. Read More
Ten years ago this month, the run on Lehman Brothers kicked off the third and final phase of the Great Financial Crisis (GFC) of 2007-2009. In two earlier posts (here and here), we describe the prior phases of the crisis. The first began on August 9, 2007, when BNP Paribas suspended redemptions from three mutual funds invested in U.S. subprime debt, kicking off a global scramble for safe, liquid assets. And the second started seven months later when, in response to the March 2008 run on Bear Stearns, the Fed provided liquidity directly to nonbanks for the first time since the Great Depression, completing its crisis-driven evolution into an effective lender of last resort to solvent, but illiquid intermediaries.
The most intense period of the crisis began with the failure of Lehman Brothers on September 15, 2008. Credit dried up; not just uncollateralized lending, but short-term lending backed by investment-grade collateral as well. In mid-September, measures of financial stress spiked far above levels seen before or since (see here and here). And, the spillover to the real economy was rapid and dramatic, with the U.S. economy plunging that autumn at the fastest pace since quarterly reporting began in 1947.
In our view, three, interrelated policy responses proved critical in arresting the crisis and promoting recovery. First was the Fed’s aggressive monetary stimulus: after Lehman, within its mandate, the Fed did “whatever it took” to end the crisis. Second was the use of taxpayer resources—authorized by Congress—to recapitalize the U.S. financial system. And third, was the exceptional disclosure mechanism introduced by the Federal Reserve in early 2009—the first round of macroprudential stress tests known as the Supervisory Capital Assessment Program (SCAP)—that neutralized the worst fears about U.S. banks.
In this post, we begin with a bit of background, highlighting the aggregate capital shortfall of the U.S. financial system as the source of the crisis. We then turn to the policy response. Because we have discussed unconventional monetary policy in some detail in previous posts (here and here), our focus here is on the stress tests (combined with recapitalization) as a central means for restoring confidence in the financial system….

If there were a regulatory Richter scale that measured the shaking of the financial system, the 2010 Dodd-Frank Act would register about 8, while the 2011 Basel III framework might be a bit above 7. (For reference, the 1906 San Francisco earthquake was a 7.8). Fortunately, this shaking is mostly for the better – helping to make the financial system more resilient in the long run.
The new “Bailout Prevention Act” of Senators Vitter and Warren also might be an 8 on the shaking scale, but it would be a true disaster, because it undermines the Fed’s role as crisis lender of last resort. In contrast, the Senate Banking Committee’s new discussion draft of a “Financial Regulatory Improvement Act of 2015” is probably a 2 or a 3. If enacted, it will be “felt slightly by some people” but probably won't do much damage... Read More
The global financial crisis started in 2007 when European banks came under increasing strain. If forced to specify the crisis kickoff, we would pick Thursday, August 9, the day that BNP Paribas halted redemptions from three investment funds because it couldn’t value their holdings of U.S. mortgages. Responding to the ensuing market scramble for liquidity, the ECB injected €95 billion that day into the European banking system and the Federal Reserve put $24 billion in theirs. Today, with the benefit of hindsight, these numbers appear quaint, but then they seemed enormous... Read More
