Introduction to Financial Services: Systemic Risk

Recent Episodes of Financial Instability
The 2007-2009 financial crisis was characterized by
system-wide financial instability. Overtaken by panic,
market participants became unwilling to engage in even
routine transactions at the height of the crisis. Distress at
large financial firms was central to the crisis. Financial
stability was not restored until large-scale financial
intervention by the Federal Reserve (Fed) and Congress
helped stabilize markets and provided assistance to
financial firms. The result was a sharp and long-lasting
contraction in credit and economic activity.
The COVID-19 pandemic also caused significant financial
market turmoil in spring 2020, as investors were faced with
uncertainty and unprecedented disruptions to economic
activity. But this time, financial stability was quickly
restored, albeit again through large-scale financial
intervention by the Fed and the CARES Act (P.L. 116-136).
Unlike the previous crisis, distress at large financial firms
was not central to the instability. Both episodes suggest that
financial markets remain inherently fragile under periods of
stress, and federal interventions are likely in future episodes
of instability. This raises questions of whether further
reforms are merited to mitigate systemic risk and whether
federal interventions are acceptable.
Sources of Systemic Risk
The financial crisis highlighted that systemic risk can
emanate from financial firms, markets, or products. It can
be caused by the failure of a large firm (hence the moniker
too big to fail), or it can be caused by correlated losses
among many small market participants. Although historical
financial crises have centered on banks, nonbank financial
firms were also a source of instability in the financial crisis
and the pandemic. Boom and bust cycles in asset values or
credit availability can often be the underlying cause of
crises, with the bursting of the housing bubble in the
financial crisis a notable example. Other events unrelated to
asset values, such as a successful cyberattack on a critical
market, could also trigger financial instability in theory.
Daniel Tarullo, a former Fed governor, identified four
categories of systemic risk:
1. Domino or spillover effects-for example,
when one firm's failure imposes debilitating
losses on its counterparties.
2. Feedback loops-for example, when fire sales
of assets depress market prices, thereby
imposing losses on all investors holding the
same asset class. Another example is
deleveraging-when credit is cut in response to
financial losses, resulting in further losses.

3. Contagion effects-for example, a run in which
depositors or investors suddenly withdraw their
funds from a class of institutions or assets, such
as banks or money market funds (MMFs).
4. Disruptions to critical functions-for example,
when a market can no longer operate because of
a breakdown in market infrastructure.
Policy Response to the Financial Crisis
In the aftermath of the financial crisis, one priority for
policymakers was to contain systemic risk. In other words,
how might threats to financial stability be identified and
neutralized? Systemic risk (also called macroprudential)
regulation seeks to prevent both future financial crises and
modest breakdowns in the smooth functioning of specific
financial markets or sectors. It can be contrasted with the
traditional microprudential regulatory focus on an
individual institution's solvency.
Critiques of inadequate systemic risk regulation in the run-
up to the crisis can be placed into two categories: (1)
insufficient regulatory authority to identify or mitigate
systemic risk, partly because of financial market opacity;
and (2) shortcomings of the regulatory structure that made
it unlikely for regulators to successfully identify or respond
to systemic risks. Critics argued that in the fragmented U.S.
regulatory system, no regulator was responsible for
financial stability or focused on the bigger picture, and their
narrow mandates meant there were gaps in oversight.
The 2010 Dodd-Frank Act (DFA; P.L. 111-203) sought to
enhance regulatory authority to address specific weaknesses
revealed by the crisis (e.g., derivatives markets); reduce
opacity in certain markets (e.g., new reporting requirements
for hedge funds and derivatives); and modify the regulatory
structure to make it forward-looking and nimble enough to
respond to emerging threats. Major changes included the
following:
Financial Stability Oversight Council (FSOC). DFA
created FSOC, headed by the Treasury Secretary and
composed of the financial regulators and other financial
officials. FSOC was tasked with identifying risks to
financial stability, promoting market discipline by
eliminating expectations that the government will prevent
firms from failing, and responding to emerging threats to
financial stability. DFA also created the Office of Financial
Research (OFR) in Treasury to support FSOC.
Generally speaking, FSOC does not have rulemaking
authority to intervene when it identifies emerging threats to
stability. When one of its members has the requisite
authority, FSOC can recommend-but not require-the
member to intervene. Otherwise, it can recommend a
legislative change to Congress. It is required to produce an
