Financial Interconnectedness and Systemic Risk: The Fed’s FR Y-15

Nikhil Rao, Juan Montecino, and Gerald Epstein

At the onset of the global financial crisis, many financial institutions that engaged in risky practices were on the verge of bankruptcy as the housing market crashed. Top regulators soon discovered that shocks suffered by large banks spread quickly throughout the financial system and then to the whole economy. Those large firms, colloquially dubbed “too big to fail,” were also highly interconnected. Jane D’Arista, James Crotty, and a few other economists had identified these inter-connections, but most economists and policy makers had remained clueless.

As the crisis worsened, Fed Chairman Ben Bernanke, New York Fed President Timothy Geithner and others tried to come to grips with what was happening. They started referring to Citibank, Bank of America, Goldman Sachs and other banks as “systemically important,” though former regulator Bill Black more aptly referred to them as “systemically dangerous”. A systemically important/dangerous institution is one that is so large and well-connected to other firms that shocks it suffers are transmitted to many other participants in that system. When these systemically important firms were failing, taxpayers bore the brunt of the impact as the government was compelled to inject massive amounts of taxpayer funds, or face massive economic losses, damages, and inefficiencies. This, of course, gave rise to the now well-known problem of moral hazard, where actors that do not directly bear the costs of risks are incentivized to pile on more risk. Taking into account the potential effects of systemically important firms, it is easy to understand why they can be closely associated with institutions that are “too big to fail.”

Tackling the scourge of systemically dangerous financial firms requires a theoretical and empirical understanding of their evolution and dynamics. But before the Great Recession, only a few academics analyzed situations in which market participants were of similar sizes and they found that interbank deposits could act as primary channels for liquidity shocks (Allen, Franklin, Gale ). Some other scholars concluded that interbank credit extensions could result in banks that were “too interconnected to fail” (Freixas, Parigi, Rochet). Recent academic research suggests that this may lead to the exacerbation of externalities. Further post-crisis studies considered sectors or market systems that did not have equal-sized participants. They concluded that shocks to the most interconnected banks spread widely across the financial system (Gai, Haldane, Kapadia) and that large interbank exposures were linked with systemic risk (Cont, Moussa, Santos).

While some progress has been made on understanding theoretical linkages, prior to the crisis, data collection and action by the relevant regulators lagged behind. Some recent estimates of intra-financial lending have tried to fill this gap. But these estimates have had to rely on sectoral, not bank level, data and can therefore be, at best, “guesstimates” of the interconnections (Montecino, Epstein, Levina ). In a step forward, the Dodd-Frank financial reform bill passed in 2010 created a special designation for “systemically important financial firms” and directed the regulators, especially the Federal Reserve, to strengthen their information gathering and regulatory focus with respect to these firms.

Now, late to the game, regulators such as the Basel Committee on Banking Supervision (BCBS) have sought to identify certain characteristics that determine an institution’s level of systemic importance, and interconnectedness is one of them (Federal Reserve, BIS). And finally, the Federal Reserve has begun collecting and disseminating data on the contributions of large financial institutions—dubbed “globally systemically important banks” (G-SIB)—to systemic risk. An important feature of this new FR Y-15 report is the measurement of intra-financial activities via the “Interconnectedness Indicators” in Schedule B and the data collected is similar to BCBS’s assessment of global systemic risk. The FR Y-15 report is accessible on the National Information Center’s website and covers holding companies (banks and Savings & Loans) with total assets of $50 billion or more as of June 30 of the reporting year. Of the 39 holding companies listed as having total assets of greater than $50 billion, 33 banks filed the report, with AIG, GE Capital, Teachers Insurance and Annuity Association, Charles Schwab, State Farm Mutual, and United Services as exceptions.

This new data source gives us an unprecedented level of detail on intra-financial links and other aspects of systemic risk. These data suggest that high levels of intra-financial assets are held by the very largest banks. Other banks appear to hold relatively low levels of intra-financial assets. In fact, 26 of the 33 institutions in question held relatively low amounts of intra-financial assets that ranged from 1.5 to 44 billion dollars.

But seven of the largest banks held very large amounts of intra-financial assets and therefore are also the most interconnected. These seven institutions—J.P. Morgan, Citigroup, Bank of America, Wells Fargo, Goldman Sachs, Morgan Stanley, Bank of New York Mellon—have become household names in the narrative of the financial crisis and bailout. These data give an unprecedented picture on their intra-financial connections. The figure below shows, using intra-financial assets as a share of each bank’s total assets, the most interconnected banks. The figures range from 10% of total assets to a whopping 65% by Morgan Stanley; almost 40% of Goldman Sachs’ assets were intra-financial assets.

These reported data on the intra-financial lending of the largest banks are roughly in line with the estimates based on macro data made by Montecino, Epstein and Levina, who found that intra-financial assets on average comprised about 25% of total assets in the 2000’s (Montecino, Epstein, Levina). These data, though, are based on detailed bank level data and show that some banks, for instance Morgan Stanley, have truly astounding levels of intra-financial assets.

These highly detailed data allow us to drill down and look at specific intra-financial assets. A closer look at the data reveal, for example, that a significant portion of intra-financial assets held by institutions are in the form of Over the Counter (OTC) derivatives associated with unaffiliated third party firms. In fact, amongst the largest banks, OTC derivatives constitute between 6% and 27% of intra-financial assets.

Some doubt that more transparency and information such as contained in this new data set will do much to diminish the dangers arising from interconnectedness. But, in fact, there are already provisions in law requiring the regulators to use data such as these to limit dangerous levels of intra-financial exposures. As Jane D’Arista has emphasized, sections 609, 610 and 611 of the Dodd-Frank Act require the implementation of restrictions on various kinds of credit exposures to other financial institutions. The Volcker Rule, which limits proprietary trading, can also help. Yet, as with much of Dodd-Frank, the strength of the implementation and enforcement of these provisions remains questionable due to the opposition of banks and the connivance of legislators. Other structural solutions have been proposed. For example, breaking up the too big and too interconnected to fail banks is a popular suggestion.

To be sure, better information on these dangers is not sufficient to solve these problems. The key now is to use the information to implement the necessary changes, starting with strictly enforcing the laws that are on the books. If proper measures are not undertaken to curb interconnectedness, it is possible that another unmitigated financial disaster is in the offing.
