The International Financial Crisis: Asset Price Exuberance and
Macroprudential Regulation
2009 International Banking Conference
Chicago, IL
Thank you, Justin I'm Charlie Evans, President and CEO of the Federal Reserve Bank of Chicago On behalf of the World Bank
and everyone here at the Chicago Fed, it's my pleasure to welcome you to the 12th annual International Banking Conference
Over the years, this conference has served as a valuable forum for the discussion of current issues a ecting global nancial
markets, such as international regulatory structures, the globalization of nancial markets, systemic risk, and the problems
involved with the resolution of large, globally active banks Also, we have been fortunate to have leading academics, regulators,
and industry executives participate in the various venues—providing valuable perspectives and enriching the discussions on the
issues
This year's theme is the international nancial crisis If you look back at the past conferences, you will see that the most
common theme over the years deals with various aspects of nancial crises After looking over this year's program, I want to
compliment the organizers from both the World Bank and the Chicago Fed for putting together a very impressive group of
experts in the current debate on how best to reduce the probability of another nancial crisis, and, if one should occur, how to
respond I look forward to the next two days and believe you will nd the discussion cutting edge and useful for deciding how
we as a global nancial community should move forward Again, on behalf of the World Bank and the Federal Reserve Bank of
Chicago, enjoy the 12th annual International Banking Conference
Before I turn the podium over to Doug, I'd like to o er a few remarks on the theme of this year's conference— nancial crisis—
with an emphasis on the oversight of nancial markets I should note that my remarks re ect my own views and are not those
of the Federal Open Market Committee or the Federal Reserve System
When thinking about the events of the past couple of years, what comes to mind most often, or the big "take away" from all of
this, is that we don't ever want to nd ourselves in this situation again
If we are committed to that outcome, we should ask ourselves, rst, how can policies be changed so that in the future, it will be
much less likely that systemically important nancial institutions will nd themselves in crisis situations? And, second, if such
crises do occur, how can we best contain them, preventing them from having a major impact on the rest of the economy as in
the recent crisis? Surely, prevention should form our rst and strongest line of defense and remedial, or containment, policies
should form the second
I recently gave a speech to the European Economic and Financial Center on the issues associated with too-big-to-fail I argued
that in the current regulatory environment it is unrealistic to expect that regulators would allow the uncontrolled failure of a
large, complicated, and interconnected nancial institution—certainly not if they had the ability to avoid it and if there were
systemic rami cations to the failure If you accept this premise, and I believe the failure of Lehman Brothers is the
counterexample that proves it, then it becomes imperative to construct an environment that prevents our economic and
nancial system from again reaching the crisis state we have seen over this past year
In my earlier speech I stressed the need for policy reforms, such as the introduction of an orderly and e cient failure
resolution process that would create a credible regulatory environment in which rms and their creditors would not expect
rescues or bailouts This would reduce the moral hazard issues associated with the too-big-to-fail perception It also would
better align the incentives of the stakeholders of nancial rms with those of society at large In addition it would allow a
larger role for nancial markets to oversee and regulate rm behavior However, even though I think we can signi cantly
strengthen the role of market discipline, regulation will continue to play a very important role in ensuring nancial stability
The kinds of events that lead to our recent interventions inevitably occur during periods of nancial exuberance One way or
another, asset prices rise beyond conservative fundamental valuations and risk premiums fall well below appropriate
compensation levels We typically use the loose term "asset price bubble" to describe such situations Although I will continue
that tradition, we should keep in mind that not all increases in asset prices represent departures from fundamentals, and not all
1
asset bubbles need be disruptive De nitions aside, it seems clear that we need to nd a way to deal with potential exuberance
in nancial markets if we want to ensure nancial stability
Some seven years ago, at an earlier International Banking Conference, which was also cosponsored by the World Bank, we
2
discussed the implications of asset bubbles The typical view expressed at the conference, which aligned well with much of the
research literature at the time, was that central banks should not use monetary policy tools to "manage" or lean against the
in ated prices associated with asset bubbles In the event of a sudden collapse in asset prices, central banks were expected to
respond with their standard policy tools to address any adverse impact on real economic activity In other words, monetary
3
policy should be prepared to "clean up" ex post rather than try to prevent ex ante a run-up in asset prices
However, given the enormous costs of the recent nancial crisis, as well as new research suggesting an increase in the
4
frequency and amplitude of asset price cycles, many commentators are reassessing the proper role of the central bank in
monitoring and trying to de ate rising asset prices
In reevaluating the e ectiveness of monetary policy for this purpose, two approaches are typically considered One is for the
central bank to take an activist role and directly incorporate asset price uctuations into its monetary policy deliberations—that
is, explicitly putting asset prices into the policy response function and "leaning against the wind " As an alternative,
policymakers could incorporate asset prices into the price indexes used in determining the future direction of monetary policy
While recent events have indeed imposed signi cant costs on society, I fear that monetary policy tools may be too blunt for
5
such a ne-tuning policy Central bankers have imperfect information, and for many asset classes, sudden price declines may
6
have minimal impact on the real economy So, my concern is that using monetary policy to "lean against bubbles" could end
up causing more harm to the economy than good
To elaborate a bit, taking an activist role would likely have policy aim at explicitly hitting some target range for asset prices or
risk premiums So, we would rst have to determine those target ranges I don't know of any economic theory or empirical
evidence we currently have in hand that would give us adequate guidance here In addition, there is the "bluntness" of monetary
policy Using wide-reaching monetary policy to slow the growth of certain asset prices could have signi cant adverse e ects on
other sectors of the economy In normal times, we use our policy instrument, the short-term federal funds rate, to try to
achieve our dual mandate goals of maximum sustainable employment and price stability Adding a third target—asset prices—
would likely mean we couldn't do as well on the other two
The desirability of incorporating asset prices into the in ation measures targeted by central banks is also not obvious Some
claim that standard consumer price indexes do not adequately incorporate in ationary expectations; rather, they only account
for past price adjustments Certain asset prices, for example, those of equities or real estate, may better incorporate such
expectations Thus, some argue that to the extent these asset prices are predictors of future price changes, including them in
the target price indexes provides a reasonable operating procedure that leans against rising asset prices and adds an automatic
stabilizer to monetary policy
One potential issue with this argument is whether real estate or equity market prices accurately forecast future in ation rates
A bigger question, however, is how to operationalize such an index What weights should be assigned to asset prices in the
aggregate indexes? Index number theory provides the conceptual linkage between utility maximization and the expenditure
weights used to construct consumer price indexes I have not yet seen the theoretical work that says how to include asset prices
in an aggregate index I am open-minded to new research making the case for using monetary policy to address asset in ation
7
But as of now, I am skeptical
Fortunately, monetary policy is not the only tool that central banks have to deal with asset price swings and their potentially
disruptive consequences In my view, redesigning regulations and improving market infrastructure o er more promising paths
to increased nancial stability This is the "prevention" that forms the rst line of defense in our e orts to never be in this
position again Regulation may or may not be su cient to avoid all of the market events that help to create excessive
exuberance, but it should play a very large role in controlling the existence, size, and consequences of any bubble For example,
research suggests that a crisis caused by sudden declines in asset prices is less disruptive to markets when nancial systems and
8
individual bank balance sheets are in sound condition before the crisis Better supervision and a sound regulatory
infrastructure can increase the resiliency of markets and institutions, enabling them to better withstand adverse shocks
How do we promote such increased resiliency? First, we can make more e ective use of our existing regulatory structure, tools,
and authority And second, a number of reforms of our current infrastructure—both market and regulatory—may help us to
better address the type of problems we saw emerge during the recent crisis
Within the existing structure, regulators have the ability to promote better, more resilient nancial markets, either through
9
rule-making or by serving as a coordinator of private initiatives They can also encourage more and better disclosure of
information—a key element of e ective risk management
Regulators and supervisors are also often in positions to foresee emerging problems before they grow into crises Along these
lines, supervisors can do more "horizontal supervision," similar to the Supervisory Capital Assessment Program SCAP that was
designed for the largest 19 U S banks Using procedures similar to those in SCAP, the likely performance of banks can be
evaluated on a consistent basis under alternative stress scenarios In addition to evaluating resiliency to future conditions, this
type of "stress test" also enables supervisors to identify best practices in risk management and to push banks with weak risk
10
management to improve
When emerging issues or practices that could lead to disruptions are identi ed, regulators can more e ectively use tools such
11
as memorandums of understanding or supervisory directives to dampen the adverse impact of a variety of nancial shocks
Indeed, we probably should have been more aggressive in utilizing this supervisory power during the period leading up to the
recent crisis It can be an e ective and powerful tool
Although I believe we can use existing regulatory tools more e ectively, we may also need to address the shortcomings of
12
current regulations Already policymakers in the U S and elsewhere are exploring a variety of reforms
Introducing a systemic regulator who can identify, monitor, and collate information on industry practices across various
institutions tops most of the reform agendas While plans for systemic regulation vary in the structures they propose—for
example, a single regulator versus a committee of regulators—they all envision macroprudential supervision and regulation as
the key mandate of the new regulator This would be a major component of what I called our rst line of defense
Reform proposals also typically include ways in which we can make capital requirements more dynamic and tailor them to the
type of risks an institution poses for the nancial system Varying capital requirements and loan loss provisions over the cycle
are examples of these proposals History shows that during boom times, when nancial institutions are perhaps in an exuberant
state, they may not price risks fully in their underwriting and risk-management decisions During downturns, faced with
eroding capital cushions, increased uncertainty, and binding capital constraints, some institutions may become overcautious and
excessively tighten lending standards Both behaviors tend to amplify the business cycle Allowing the required capital ratio to
vary over the cycle could serve to o set some of this volatility and to partially o set the boom–bust trends we have seen in the
past
Varying loan loss provisions over the cycle is an alternative or complementary way to better cushion rms against sudden
declines in asset prices
Capital requirements also could be adjusted by extending risk-based weighting schemes to account for institutions'
contributions to systemic risk This could involve higher risk weights based on factors such as institution size and the extent of
o -balance-sheet activities It might also include some assessment of the degree to which the institution was interconnected
with others Such adjustments to capital requirements would make the decisions of nancial institutions more closely re ect
their impact on society The information needed to account for the new risk factors—for example, the degree of
interconnectedness— ts well within the framework of information that would be required by a new systemic regulator, and is
now being considered in regulatory reform proposals in the U S
So, in order to fortify our rst line of defense, we must make more e ective use of the existing regulatory structure and tools,
introduce a systemic risk regulator, and reform capital requirements to make them more dynamic and tailored to systemic
risks But adjustments to the current regulations and infrastructure alone are probably not enough We also need to fortify our
second line of defense—containing the disruptive spillovers that result from the failure of systemically important institutions
without resorting to bailouts or ad hoc rescues A necessary element of this is having a mechanism for resolving the failure of a
systemically important institution This is something we currently lack in many cases, though there are proposals now under
13
discussion that would provide this resolution power
Another reform proposal that I think can play an important role in the resolution process of systemically important institutions
is what is typically referred to as a "shelf bankruptcy" plan Under this proposal, systemically important institutions would be
required to provide the information necessary to determine how their failures could be handled in a relatively short period of
14
time, as well as to design a plan to e ciently implement such a resolution I see a number of ways these plans can fortify
both our rst and second lines of defense
Requiring systemically important institutions to identify and think through their organizational structure and interactions with
various parties can improve the risk-management practices of their institutions By developing plans to address systemic
problem areas ex ante, the need for an ex post "too-big-to-fail" action could be reduced
In addition, should the rst line of defense fail, these plans could provide an initial blueprint for the resolution of large
interconnected institutions and, in so doing, improve our second line of defense Currently, individual institutions may not
15
have an incentive to make such plans—after all, they would bear the costs of the planning and see little of the bene ts But,
society as a whole would bene t from such contingency planning Another way to cushion nancial rms against sudden asset
16
price declines would be to require them to hold contingent capital Under these proposals, systemically important banks
would be required to issue "contingent capital certi cates " These would be issued as debt securities that would be converted
17
into equity shares if some predetermined threshold was breached It would provide rms with an additional equity injection
at the very time that equity would be di cult to issue, thus enabling rms to better withstand sudden shocks and potential
spillover e ects
These new policy options, while not easy to implement, would enhance the ability of banks and other nancial intermediaries
to survive shocks—whether from a sudden fall in asset prices or from some other source I am fully aware that the challenges
in reforming regulatory structures and practices are not insigni cant But, given the magnitude of the cost incurred in the wake
of the recent crisis and the possible bene ts that would arise from making our economy more resilient to such events, it is
imperative that we take on these challenges
Thus, I think we need to strengthen our existing regulatory infrastructure and give strong consideration to making the
adjustments that could reduce the likelihood of a crisis similar in magnitude to the one we have seen over the past two years
We also need to devise mechanisms to dampen the adverse e ects of any disruption that might occur
This year, as in others, this conference invites us to examine and discuss nancial crises and asks whether the rules of nance
have changed I've argued that in order to avoid a situation like the one we have faced in the past two years; we need to fortify
our regulatory lines of defense We need to have the rules of regulation change Not necessarily through more regulation, but
through better regulation that is more e cient and e ective in its design and implementation I hope this conference serves as
a platform to inform your thinking and stimulate good debate about the issues I've laid out
Thank you

accelerator in a quantitative business cycle framework," in Handbook of Macroeconomics, Vol 1C, John Taylor and Michael
Woodford eds , New York: Elsevier Science-North Holland, pp 1341–1393 A quick aside, it should be emphasized that
policymakers do currently take asset bubbles into account to the extent that they a ect the real sector of the economy Thus, it
is not a question of whether policymakers address bubbles At issue is whether they should or can address asset price increases
ex ante to avoid a resulting sudden decline in prices that more adversely a ects the real economy than would have occurred
without the bubble

Crisis," Bard College, New York City, April 16

See Mishkin in footnote 5 Mishkin makes the argument that not all bubbles have the same impact on the real economy In
particular, he argues that bubbles associated with credit booms are more dangerous because they put the nancial system at
risk and may result in negative spillover e ects for the real economy Thus, these bubbles may deserve a more activist
approach

An example here would be the central bank serving a coordinative role encouraging banks to address operational risks
associated with back-o ce operations in credit default swap contracts

Committee on Banking, Housing, and Urban A airs, Washington, DC, August 4

For example, memorandums could have addressed the rising role of commercial real estate in bank portfolios, or they could
have addressed practices in mortgage lending that may have contributed to poor underwriting

See U S Department of the Treasury, 2009, "Financial regulatory reform—A new foundation: Rebuilding nancial
supervision and regulation," proposal, Washington, DC, June 17, available online I have previously discussed these policy issues
in somewhat more detail: see Charles Evans, 2009, "Too-big-to-fail: A problem too big to ignore," speech to the European
Economics and Financial Center, London, July 1 Also see the Squam Lake Working Group proposals, available at Squam Lake

Conference on Bank Structure and Competition, Federal Reserve Bank of Chicago, May; and see the Squam Lake Working
Group proposals, available at Squam Lake Working Group proposals
15
Not only would the banks not see the bene ts of disclosing this information, they could actually bene t from keeping this
information from the supervisors The more opaque the operations and risk of institutions, the more likely they could be
considered too-big-to-fail if they encounter di culties Thus, the "shelf plan" could force these issues to be on the table for
discussion
16
See Mark Flannery, 2005, "No pain, no gain? E ecting market discipline via reverse convertible debentures," in Capital
Adequacy Beyond Basel: Banking, Securities, and Insurance, Hal S Scott ed , Oxford: Oxford University Press, chapter 5; see
also the Squam Lake Working Group on Financial Regulation, Squam Lake Working Group proposals, available at Squam Lake
Working Group on Financial Regulation
17
This would be somewhat similar to previous proposals to require banks to hold subordinated debt to better discipline bank
behavior and to be able to absorb losses when di culties are encountered See Douglas Evano and Larry Wall, 2000,
"Subordinated debt as bank capital: A proposal for regulatory reform," Economic Perspectives, Federal Reserve Bank of Chicago,
Vol 24, No, 2, Second Quarter, pp 40–53 However, the convertibility of the new instrument would most likely occur when
the bank is better capitalized, thus augmenting equity capital and providing an earlier cushion against losses The trigger to
convert the debt would most likely also be supervisory instead of market induced
