Abstract
The rapid growth of the market-based nancial system since the mid-1980s changed the
nature of nancial intermediation. Within the market-based nancial system, “shadow
banks” have served a critical role. Shadow banks are nancial intermediaries that con-
duct maturity, credit, and liquidity transformation without explicit access to central bank
liquidity or public sector credit guarantees. Examples ofshadow banks include nance
companies, asset-backed commercial paper (ABCP) conduits, structured investment
vehicles (SIVs), credit hedge funds, money market mutual funds, securities lenders,
limited-purpose nance companies (LPFCs), and the government-sponsored enterprises
(GSEs). Our paper documents the institutional features ofshadow banks, discusses their
economic roles, and analyzes their relation to the traditional banking system. Our de-
scription and taxonomy ofshadowbank entities and shadowbank activities are accom-
panied by “shadow banking maps” that schematically represent the funding ows of the
shadow banking system.
Key words: shadow banking, nancial intermediation

1. Introduction
Shadow banks intermediate credit through a wide range of securitization and secured funding
techniques such as asset-backed commercial paper (ABCP), asset-backed securities (ABS),
collateralized debt obligations (CDOs) and repurchase agreements (repos). These securities are used
by specialized shadowbank intermediaries that are bound together along an intermediation chain.
We refer to the network ofshadow banks in this intermediation chain as the shadowbanking
system. While we believe that shadowbanking is a somewhat pejorative name for such a large and
important part of the financial system, we adopt it in this paper.
Over the past decade, the shadowbanking system provided sources of funding for credit by
converting opaque, risky, long-term assets into money-like, short-term liabilities. Arguably, maturity
and credit transformation in the shadowbanking system contributed to the asset price appreciation
in residential and commercial real estate markets prior to the 2007-09 financial crisis. During the
financial crisis, the shadowbanking system became severely strained and many parts of the system
collapsed. Credit creation through maturity, credit, and liquidity transformation can significantly
reduce the cost of credit relative to direct lending. However, credit intermediaries’ reliance on short-
term liabilities to fund illiquid long-term assets is an inherently fragile activity and may be prone to
runs.
1
1
There is a large literature on bank runs modeled as multiple equilibria initiated by Diamond and
Dybvig (1983). Morris and Shin (2004) provide a model of funding fragility with a unique
equilibrium in a setting with higher order beliefs. Martin, Skeie and von Thadden (2011) provide a
theory of runs in the repo market.
As the failure of credit intermediaries can have large, adverse effects on the real economy (see
Bernanke (1983) and Ashcraft (2005)), governments chose to shield them from the risks inherent in
reliance on short-term funding by granting them access to liquidity and credit put options in the
form of discount window access and deposit insurance, respectively.
2
Shadow banks conduct credit, maturity and liquidity transformation similar to traditional banks.
However, what distinguishes shadow banks from traditional banks is their lack of access to public
sources of liquidity such as the Federal Reserve’s discount window, or public sources of insurance
such as Federal Deposit Insurance. The emergency liquidity facilities launched by the Federal
Reserve and other government agencies’ guarantee schemes created during the financial crisis were
direct responses to the liquidity and capital shortfalls ofshadow banks. These facilities effectively
provided a backstop to credit intermediation by the shadowbanking system and to traditional banks
for their exposure to shadow banks.
In contrast to public-sector guarantees of the traditional banking system, prior to the onset of the
financial crisis of 2007-2009, the shadowbanking system was presumed to be safe due to liquidity
and credit puts provided by the private sector. These puts underpinned the perceived risk-free,
highly liquid nature of most AAA-rated assets that collateralized credit repos and shadow banks’
liabilities more broadly. However, once private sector put providers’ solvency was questioned, even
if solvency was perfectly satisfactory in some cases, the confidence that underpinned the stability of
the shadowbanking system vanished. The run on the shadowbanking system, which began in the
summer of 2007 and peaked following the failure of Lehman in September and October 2008, was
stabilized only after the creation of a series of official liquidity facilities and credit guarantees that
replaced private sector guarantees entirely. In the interim, large portions of the shadowbanking
system were eroded.
The failure of private sector guarantees to support the shadowbanking system stemmed largely
from the underestimation of asset price correlations by every relevant party: credit rating agencies,
risk managers, investors, and regulators. Specifically, they did not account for the fact that the prices
of highly rated structured securities become much more correlated in extreme environments than in
3
normal times. In a major systemic event, the price behavior of diverse assets become highly
correlated as investors and levered institutions are forced to shed assets in order to generate the
liquidity necessary to meet margin calls (see Coval, Jurek and Stafford (2009)). Mark-to-market
leverage constraints result in pressure on market-based balance sheets (see Adrian and Shin (2010a),
and Geanakoplos (2010)). The underestimation of correlation enabled financial institutions to hold
insufficient amounts of liquidity and capital against the puts that underpinned the stability of the
shadow banking system, which made these puts unduly cheap to sell. As investors also
overestimated the value of private credit and liquidity enhancement purchased through these puts,
the result was an excess supply of cheap credit.
The AAA assets and liabilities that collateralized and funded the shadowbanking system were the
product of a range of securitization and secured lending techniques. Securitization-based credit
intermediation process has the potential to increase the efficiency of credit intermediation.
However, securitization-based credit intermediation also creates agency problems which do not exist
when these activities are conducted within a bank. In fact, Ashcraft and Schuermann (2007)
document seven agency problems that arise in the securitization markets. If these agency problems
are not adequately mitigated with effective mechanisms, the financial system has weaker defenses
against the supply of poorly underwritten loans and aggressively structured securities.
Overviews of the shadowbanking system are provided by Pozsar (2008) and Adrian and Shin
(2009). Pozsar (2008) catalogues different types ofshadow banks and describes the asset and
funding flows within the shadowbanking system. Adrian and Shin (2009) focus on the role of
security brokers and dealers in the shadowbanking system, and discuss implications for financial
regulation. The term “shadow banking” was coined by McCulley (2007). Gertler and Boyd (1993)
4
and Corrigan (2000) are early discussions of the role of commercial banks and the market based
financial system in financial intermediation.
The contribution of the current paper is to focus on institutional details of the shadowbanking
system, complementing a rapidly growing literature on the system’s collapse As such, our paper is
primarily descriptive, and focuses on funding flows in a somewhat mechanical manner. We believe
that the understanding of the plumbing of the shadowbanking system is an important underpinning
of any study of systemic interlinkages within the financial system.
The remainder of the paper is organized as follows. Section 2 provides a definition ofshadow
banking, and an estimate of the size ofshadowbanking activity. Section 3 discusses the seven steps
of the shadow credit intermediation process. Section 4 is by far the longest section of the paper,
describing the interaction of the shadowbanking system with institutions such as bank holding
companies and broker dealers. Finally, section 5 concludes.
2. WHAT IS SHADOW CREDIT INTERMEDIATION?
2.1 Defining ShadowBanking
In the traditional banking system, intermediation between savers and borrowers occurs in a single
entity. Savers entrust their savings to banks in the form of deposits, which banks use to fund the
extension of loans to borrowers. Savers furthermore own the equity and debt issuance of the banks.
Relative to direct lending (that is, savers lending directly to borrowers), credit intermediation
provides savers with information and risk economies of scale by reducing the costs involved in
screening and monitoring borrowers and by facilitating investments in a more diverse loan portfolio.
5
Credit intermediation involves credit, maturity, and liquidity transformation. Credit transformation
refers to the enhancement of the credit quality of debt issued by the intermediary through the use of
priority of claims. For example, the credit quality of senior deposits is better than the credit quality
of the underlying loan portfolio due to the presence of junior equity. Maturity transformation refers
to the use of short-term deposits to fund long-term loans, which creates liquidity for the saver but
exposes the intermediary to rollover and duration risks. Liquidity transformation refers to the use of
liquid instruments to fund illiquid assets. For example, a pool of illiquid whole loans might trade at
a lower price than a liquid rated security secured by the same loan pool, as certification by a credible
rating agency would reduce information asymmetries between borrowers and savers.
Credit intermediation is frequently enhanced through the use of third-party liquidity and credit
guarantees, generally in the form of liquidity or credit put options. When these guarantees are
provided by the public sector, credit intermediation is said to be officially enhanced. For example,
credit intermediation performed by depository institutions is enhanced by credit and liquidity put
options provided through deposit insurance and access to central bank liquidity, respectively.
Exhibit 1 lays out the framework by which we analyze official enhancements.
2
1. A liability with direct official enhancement must reside on a financial institution’s balance sheet,
while off-balance sheet liabilities of financial institutions are indirectly enhanced by the public
sector. Activities with direct and explicit official enhancement include on-balance sheet funding
Thus, official
enhancements to credit intermediation activities have four levels of “strength” and can be classified
as either direct or indirect, and either explicit or implicit.
2
The analysis of deposit insurance was formally analyzed by Merton (1977) and Merton and Bodie (1993).

of depository institutions; insurance policies and annuity contracts; the liabilities of most pension
funds; and debt guaranteed through public-sector lending programs.
3
2. Activities with direct and implicit official enhancement include debt issued or guaranteed by the
government sponsored enterprises, which benefit from an implicit credit put to the taxpayer.
3. Activities with indirect official enhancement generally include for example the off-balance sheet
activities of depository institutions like unfunded credit card loan commitments and lines of
credit to conduits.
4. Finally, activities with indirect and implicit official enhancement include asset management
activities such as bank-affiliated hedge funds and money market mutual funds, and securities
lending activities of custodian banks. While financial intermediary liabilities with an explicit
enhancement benefit from official sector puts, liabilities enhanced with an implicit credit put
option might not benefit from such enhancements ex post.
In addition to credit intermediation activities that are enhanced by liquidity and credit puts provided
by the public sector, there exist a wide range of credit intermediation activities which take place
without official credit enhancements. These credit intermediation activities are said to be
unenhanced. For example, the securities lending activities of insurance companies, pension funds
and certain asset managers do not benefit from access to official liquidity.
We define shadow credit intermediation to include all credit intermediation activities that are
implicitly enhanced, indirectly enhanced or unenhanced by official guarantees (points 2.), 3.) and 4.)
from above).

Depository institutions, including commercial banks, thrifts, credit unions, federal savings banks and
industrial loan companies, benefit from federal deposit insurance and access to official liquidity backstops
from the discount window. Insurance companies benefit from guarantees provided by state guaranty
associations. Defined benefit private pensions benefit from insurance provided by the Pension Benefit
Guaranty Corporation (PBGC), and public pensions benefit from implicit insurance provided by their state,
municipal, or federal sponsors. The Small Business Administration, Department of Education, and Federal
Housing Administration each operate programs that provide explicit credit enhancement to private lending.

2.2 Sizing the ShadowBanking System
Before describing the shadow intermediation process in detail, we begin by reporting a gauge of the
size ofshadowbanking activity. Figure 1 provides two measures of the shadowbanking system, net
and gross, both computed from the FederalReserve Board’s flow of funds. The gross measure
sums all liabilities recorded in the flow of funds that relate to securitization activity (MBS, ABS, and
other GSE liabilities), as well as all short term money market transactions that are not backstopped
