The Extraordinary Failures Exposed by Silicon Valley Bank's Collapse

The collapse of Silicon Valley Bank (SVB) revealed an extraordinary range of astonishing failures. There was the failure of the bank’s executives to manage the maturity and liquidity risks that are basic to the business of banking: they failed Money and Banking 101. There was the failure of market discipline by investors who either didn’t notice or didn’t care about the fact that the bank was severely undercapitalized for the better part of a year before it collapsed. There was the failure of the supervisors to compel the bank to manage the simplest and most obvious risks. And, there was the failure of the resolution authorities to act in mid-2022 when SVB’s true net worth had sunk far below the minimum threshold for “prompt corrective action.”

Waiting several quarters to act deepened the threat to the financial system, undermining confidence not only in many other banks but also in the competence of the supervisors. The extraordinary rescue actions last week by both the deposit insurer (FDIC) and the lender of last resort (Federal Reserve) are just a sign of the high costs associated with restoring financial stability when confidence plunges.

In this post we discuss each of these four failures, as well as the actions that authorities took to stabilize the financial system following the SVB failure. To anticipate our conclusions, we see an urgent need for officials to do at least five things:

  • First, to regain credibility, supervisors need to do an immediate review of the unrealized losses on the balance sheets of all 45 banks with assets in excess of $50 billion.

  • Second, they should perform a speedy and focused stress test on each of these banks to assess the  impact on their true net worth of a sizable further increase in interest rates. Any bank with a capital shortfall should be compelled either to issue new equity or shut down. (To ensure the availability of the necessary resources, authorities will need to have a pool of public funds available to recapitalize banks that cannot attract private investors.)

  • Third, to restore resilience, Congress must reverse the 2018-19 weakening of regulation that allowed medium-size banks to escape rigorous capital and liquidity requirements.

  • Fourth, the authorities must change accounting rules to ensure that reported capital more accurately reflects each bank’s true financial condition.

  • Finally, policymakers should assess the impact on the financial system and on the federal debt arising from the now-implicit promise to insure all deposits in a crisis. To limit risk taking, correspondingly greater fees and higher capital and liquidity requirements should accompany any explicit increase in the cap on deposit insurance.

Stress Testing Financial Networks: The Case of CCPs

Following the crisis of 2007-09, in which AIG’s bilateral derivatives trades played a notable role, the G20 leaders called for central clearing of standardized derivatives. The resulting shift has been dramatic: central counterparties (CCPs) now clear about three-fourths of interest rate contracts, up from less than one-fourth a decade earlier (see Faruqui, Huang and Takáts).

By substituting a CCP as the buyer to every seller and the seller to every buyer, central clearing mutualizes and can—with appropriate margining, trade compression, position liquidation procedures, and reporting—reduce counterparty risk (see Tuckman). CCPs also contribute to financial resilience by promoting uniform margin standards, reducing collateral and liquidity needs, and making risk concentrations (like that of AIG in the run-up to the crisis) more transparent.

At the same time, the shift to central clearing has concentrated risk in the CCPs themselves. Reflecting economies of scale and scope, as well as network externalities, a few CCPs serving global clearing needs have grown enormous. For example, as of the last report at end-September 2018, open interest at LCH Clearnet exceeded $250 trillion. Moreover, the clearing activity of some CCPs lacks any short-run substitute. As a result, to avoid disrupting large swathes of the global financial system, any recovery or resolution plan for these CCPs must ensure continuity of service (see CCP Resolution Working Group presentation to the OFR Financial Research Advisory Committee). Finally, CCPs are the most interconnected intermediaries on the planet, making them channels for transmission and amplification of financial distress within and across jurisdictions. As then-Governor Powell clearly states in the opening quote, the safety of CCPs is central to the resilience of the global financial system.

We and Richard Berner have been studying how regulators use stress tests (see our earlier posts here and here) to assess the resilience of financial networks, including banks and nonbanks. In our joint work, we focus on CCPs due to their centrality, their extreme interconnectedness and their lack of substitutability. This post is based on our research….

The Scandal is What's Legal

If you haven’t seen The Big Short, you should. The acting is superb and the story enlightening: a few brilliant outcasts each discover just how big the holes are that eventually bury the U.S. financial system in the crisis of 2007-2009. If you’re like most people we know, you’ll walk away delighted by the movie and disturbed by the reality it captures. [Full disclosure: one of us joined a panel organized by the film’s economic consultant to view and discuss it with the director.]

But we're not film critics, The movie—along with some misleading criticism—prompts us to clarify what we view as the prime causes of the financial crisis. The financial corruption depicted in the movie is deeply troubling (we've written about fraud and conflicts of interest in finance here and here). But what made the U.S. financial system so fragile a decade ago, and what made the crisis so deep, were practices that were completely legal. The scandal is that we still haven't addressed these properly....

Conflicts of Interest in Finance

Angered by a foreign downing of a U.S. airliner, and frustrated by the ineffectiveness of customary retaliation, fictional West Wing President Bartlet challenged his military advisors to devise a “disproportional response” that would go beyond “the cost of doing business” to deter future attacks and make Americans safe.

Financial corruption does not put our lives directly at stake. Yet, it is easy to imagine how widespread and recurring corruption could lead a future U.S. President – frustrated by the failure of markets, regulators, and the courts to change financial intermediaries for the better – to ask her financial and legal advisors for a similar disproportional response to make Americans safe...
