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…. Read More
As memories of the 2007-09 financial crisis fade, we worry that complacency is setting in. Recent news is not good. In the name of reducing the regulatory burden on small and some medium-sized firms, the Congress and the President enacted legislation that eased the requirements on some of the largest firms. Under the current Administration, several Treasury reports travel the same road, proposing ways to ease regulatory scrutiny of large entities without changing the law (see here, here and here). And, recently, the Federal Reserve Board altered its stress test in ways that make it more likely that poorly managed firms will pass. It also voted not to raise capital requirements on systemically risky banks over the next 12 months.
A few weeks ago, one of us (Steve) had the privilege to speak at the 20th Risk Convention of the Global Association of Risk Professionals (GARP). Founded in 1996, GARP engages in the education and certification of risk professionals and has several hundred thousand members worldwide. (Disclosure: Brandeis International Business School and NYU Stern are GARP Academic Partners.) The organizers allowed us to solicit the views of the 100-plus attendees on two issues that are central to financial resilience: Are bank capital requirements high enough? And, do central counterparties (CCPs) have sufficient loss-absorbing buffers? They answered both questions with a resounding “NO” …. Read More
Bitcoin is all the rage, again. Last week, the price rose above $10,000 for the first time. Following a Friday announcement by the Commodity Futures Trading Commission, the Chicago Mercantile Exchange, the CBOE Futures Exchange, and the Cantor Exchange appear poised to launch Bitcoin futures or other derivatives contracts, with Nasdaq likely to follow. Portfolio advisers are encouraging cryptocurrency diversification. In London’s Metro, advertisements assure potential investors that “Crypto needn’t be cryptic.” And, as skyrocketing prices gain headlines, less sophisticated investors are diving in.
The danger is that investors will interpret the surging price itself (and the associated hullabaloo) as a sufficient signal to buy, fueling an asset price bubble (and, eventually, a painful crash).
No one can ever say with certainty when an asset price boom is a bubble. Nevertheless, it makes sense to ask what fundamental services Bitcoin provides. More specifically, have the prospects for those services improved sufficiently over the past year to warrant the 10-fold increase in price that has vaulted Bitcoin’s market capitalization into the range of the top 50 U.S. firms?
We strongly doubt it.... Read More
Clean water and electric power are essential for modern life. In the same way, the financial infrastructure is the foundation for our economic system. Most of us take all three of these, water, electricity and finance, for granted, assuming they will operate through thick and thin.
As engineers know well, a system’s resilience depends critically on the design of its infrastructure. Recently, we discussed the chaos created by the October 1987 stock market crash, noting the problems associated with the mechanisms for trading and clearing of derivatives. Here, we take off where that discussion left off and elaborate on the challenge of designing a safe derivatives trading system―safe, that is, in the sense that it does not contribute to systemic risk.
Today’s infrastructure is significantly different from that of 1987. In the aftermath of the 2007-09 financial crisis, authorities in the advanced economies committed to overhaul over-the-counter (OTC) derivatives markets. The goal is to replace bilateral OTC trading with a central clearing party (CCP) that is the buyer to every seller and the seller to every buyer.... Read More
On Monday, October 19, 1987, the Dow Jones Industrial Average plunged 22.6 percent, nearly twice the next largest drop—the 12.8 percent Great Crash on October 28, 1929, that heralded the Great Depression.
What stands out is not the scale of the decline—it is far smaller than the 90 percent peak-to-trough drop of the early 1930s—but its extraordinary speed. A range of financial market and institutional dislocations accompanied this rapid plunge, threatening not just stocks and related instruments (domestically and globally), but also the U.S. supply of credit and the payments system. As a result, Black Monday has been labeled “the first contemporary global financial crisis.” And, a new book—A First-Class Catastrophe—narrates the tense human drama that it created for market and government officials. A movie seems sure to follow.
Our reading of history suggests that it was only with a great dose of serendipity that we escaped catastrophe in 1987. Knowing that fortune usually favors the well prepared, the near-collapse on Black Monday prompted market participants, regulators, the lender of last resort, and legislators to fortify the financial system.
In this post, we review key aspects of the 1987 crash and discuss subsequent steps taken to improve the resilience of the financial system. We also highlight a key lingering vulnerability: we still have no mechanism for managing the insolvency of critical payment, clearing and settlement (PCS) institutions.... Read More
Eight years after the financial crisis began, the regulatory reforms it spawned continue apace. Over the past year, regulators introduced total loss absorbing capacity (TLAC) and the liquidity coverage ratio (LCR) to make banks more resilient. And, with an eye toward strengthening market function, authorities continue to push for central clearing of derivatives (CCPs).
Overlapping with these goals—and extending to nonbanks—is the recent move to establish standards for margin requirements in securities transactions: that is, the maximum amount that someone can borrow when using a given security as collateral... Read More
Among the many reforms in the aftermath of the financial crisis is the agreement among international regulators that all over-the-counter (OTC) derivatives contracts should be reported to trade repositories. The goal is to help market participants and regulators gain a better understanding of the extent and distribution of risk taking in financial markets. G-20 leaders committed to this and other improvements to financial market infrastructure (we described the move to central clearing parties (CCPs) in earlier posts). But, unlike the shift to CCPs, trade repositories seem very unlikely to meet officials’ lofty aspirations in the next few years... Read More
