Financial Crisis: The Endgame

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….

Banks and Money, Or Watch out What You Wish For

On 10 June 2008, a large majority of voters in Switzerland rejected a proposal that all commercial bank demand deposits be held at the central bank. This Vollgeld referendum was another incarnation of the justifiable public revulsion to financial crises and the bailouts that inevitably accompany them. Vollgeld proponents claimed that a system in which the central bank is the sole issuer of “money” will be more stable.

Serious people debated the wisdom of this proposal. One of Switzerland’s premier monetary economists, Philippe Bacchetta, wrote passionately in opposition. Martin Wolf, chief economics commentator at the Financial Times, argued in favor. And Swiss National Bank Chairman Thomas Jordan discussed the many dangers in detail.

It should come as no surprise that, had we had been among the Swiss voters, we would have voted “no.” In our view, the Vollgeld (sovereign money) initiative combined aspects of narrow banking with those of retail central bank digital currency. We see these as misguided, distorting the credit allocation mechanism and more likely to reduce than improve financial stability (see here and here). In the remainder of this post, we explain why….

Understanding Bank Capital: A Primer

Over the past 40 years, U.S. capital markets have grown much faster than banks, so that banks’ share of credit to the private nonfinancial sector has dropped from 55% to 34% (see BIS statistics here).  Nevertheless, banks remain a critical part of the financial system. They operate the payments system, supply credit, and serve as agents and catalysts for a wide range of other financial transactions. As a result, their well-being remains a key concern. A resilient banking system is, above all, one that has sufficient capital to weather the loan defaults and declines in asset values that will inevitably come.

In this primer, we explain the nature of bank capital, highlighting its role as a form of self-insurance providing both a buffer against unforeseen losses and an incentive to manage risk-taking. We describe some of the challenges in measuring capital and briefly discuss a range of approaches for setting capital requirements. While we do not know the optimal level of capital that banks (or other intermediaries) should be required to hold, we suggest a practical approach for setting requirements that would promote the safety of the financial system without diminishing its efficiency....

Looking Back: The Financial Crisis Began 10 Years Ago This Week

In his memorable review of 21 books about the 2007-09 financial crisis, Andrew Lo evoked Kurosawa’s classic film, Rashomon, to characterize the remarkable differences between these crisis accounts. Not only were the interpretations in dispute, but the facts were as well: “Even its starting date is unclear. Should we mark its beginning at the crest of the U.S. housing bubble in mid-2006, or with the liquidity crunch in the shadow banking system in late 2007, or with the bankruptcy filing of Lehman Brothers and the ‘breaking of the buck’ by the Reserve Primary Fund in September 2008?”

In our view, the crisis began in earnest 10 years ago this week. On August 9, 2007, BNP Paribas announced that, because their fund managers could not value the assets in three mutual funds, they were suspending redemptions. With a decade’s worth of hindsight, we view this as a propitious moment to review both the precursors and the start of the worst financial crisis since the Great Depression of the 1930s.

But, first things first: What is a financial crisis? In our view, the term refers to a sudden, unanticipated shift from a reasonably healthy equilibrium—characterized by highly liquid financial markets, low risk premia, easily available credit, and low asset price volatility—to a very unhealthy one with precisely the opposite features. We use the term “equilibrium” to reflect a persistent state of financial conditions and note that—as was the case for Humpty Dumpty—it is easy to shift from a good financial state to a bad one, but very difficult to shift back again....

The Treasury's Missed Opportunity

Last week, the U.S. Treasury published the first of four reports designed to implement the seven core principles for regulating the U.S. financial system announced in President Trump’s Executive Order 13772 (February 3, 2017).

Seven years after the passage of Dodd-Frank, it’s entirely appropriate to take stock of the changes it wrought, whether they have been effective, and whether in certain cases they went too far or in others not far enough. President Trump’s stated principles provide an attractive basis for making the financial system both more cost-effective and safer. And much of the Treasury report focuses on welcome proposals to reduce the unwarranted compliance burden imposed by a range of regulations and supervisory actions on small and medium-sized depositories that—if adequately capitalized—pose no threat to the financial system. We hope these will be viewed universally as “motherhood and apple pie.”

Unfortunately, at least when considering the largest banks, our conclusion is that adopting the Treasury’s recommendations would sacrifice resilience to achieve cost reductions, yet with little prospect for boosting economic growth. Put simply, implementation of the Treasury plan would reduce regulation of the most systemic intermediaries, and in so doing, unacceptably reduce the resilience of the U.S. financial system....

Brexit and Systemic Risk

“Is this a Lehman moment?”

In the days after the U.K. Brexit referendum, that was the leading question many people were asking. It is the right question. Unfortunately, despite years of regulatory reform in the aftermath of the financial crisis, the answer is: we don’t know. That is why policymakers are especially worried about heightened financial volatility in the aftermath of U.K. voters’ decision to leave the European Union....
