Often More Dogmatic and Less Scientific
Natasha Sarin
and Lawrence Summers of Harvard published a draft paper for the BPEA Conference
in September titled “Have
big banks gotten safer?”
The authors
use a market-based methodology to answer the question whether banks are safer
now than they were before the Great Financial Crisis (or as AA prefers to call
it The Almost a Second Great Depression) given global regulatory actions.
This post is
not meant as an analysis or critique of their work. Rather I’m using their paper to pose some
larger questions about economics, particularly market-based economics. Think of
this post as metadiscussion on themes in their paper.
Before I
begin a few disclosures.
I think that
economics is not a science per se, though a scientific approach is useful as a
heuristic tool in approaching the topic, e.g., defining terms carefully and as
precisely as possible and most importantly recognizing the limits of the
endeavor. The economy is a complex not a
complicated system. Therefore, it cannot be successfully modeled. All the mathematics in the world cannot
change this fundamental fact.
Like many who
toil in the financial world, I was raised on the prevailing standard economic
theory that invests so-called “free markets” with magical wisdom and
efficiency. That theory posits that markets are self-regulating, that is, if
left to their own processes, they reach a stable full employment (as defined) equilibrium. Extraneous shocks
not anything inherent in the market itself cause economic problems. Vigorous competition keeps participants in
the economy “honest” and largely results in maximizing social benefits. Government
regulation and taxes distort these virtuous operations. Market prices represent
the best available valuation of assets, if not always, then generally.
As my
language suggests, I am not a true believer.
It’s not that I think markets have no value. It’s that I do not think they are omniscient. Markets are also inherently unstable, that
is, economic problems result from factors within the markets not just
extraneous shocks. Market outcomes do
not always maximize social value. Market
valuations can stray from real value for prolonged periods. Homo economicus is fiction. That I suppose puts me in the Minskyite
camp.
To start things off, quotes from the abstract
in the Sarin/Summers paper. The quote is in italics. I’ve
boldfaced a few points that I want to use as springboards for my own comments.
“Since the financial crisis, there
have been major changes in the regulation of large financial institutions
directed at reducing their risk. Measures of regulatory capital have substantially
increased; leverage ratios have been reduced; and stress testing has sought to
further assure safety by raising levels of capital and reducing risk taking. Standard
financial theories would predict that such changes would lead to substantial
declines in financial market measures of risk. For major institutions in
the United States and around the world and midsized institutions in the United
States, we test this proposition using information on stock price
volatility, option-based estimates of future volatility, beta, credit default
swaps, earnings-price ratios, and preferred stock yields. To our
surprise, we find that financial market information provides little support for
the view that major institutions are significantly safer than they were before
the crisis and some support for the notion that risks have actually increased.
This does not make a case against the regulatory approaches that have been
pursued, but does caution against complacency.
We examine a number of possible
explanations for our surprising findings. We conclude that financial markets
may have underestimated risk prior to the crisis and that there may have
been significant distortions in measures of regulatory capital. While we
cannot rule out these explanations, we believe that our findings are most
consistent with a dramatic decline in the franchise value of major financial
institutions, caused at least in part by new regulations. This decline in
franchise value makes financial institutions more vulnerable to adverse shocks.
We highlight that the ratio of the market value of common equity to assets on both a
risk-adjusted and risk-unadjusted basis has declined significantly for most
major institutions. Our findings, if validated by others, may have important
implications for regulatory policy.
Now to some comments.
When Results
Differ from Theory, Question Theory
When results differ from what theory
predicts, one sensible approach is to question the theory itself, especially in this case as
markets have a history of mis-valuing assets, e.g., the dotcom boom, real
estate, etc.
While the authors do not specifically raise this point, they seem to accept that the market is not always right. “We conclude that financial markets may have underestimated risk prior to the crisis”. If markets were wrong then, why should we trust them now? If markets were carried away by irrational exuberance then, perhaps they are being carried away by rational pessimism now. Beyond that how many times does the market have to be wrong before we conclude that standard financial theory on markets is wrong or deficient? That is of course a dangerous step that could well undermine the bases for a lot of economic dogma and the politics that dogma supports.
If we assume that markets indeed can
value assets with reasonable accuracy, it’s prudent to ask whether they can
value some assets better than others.
Thus, is the market price for a Picasso as “good” (accurate) as the
market price for a US Treasury bond?
Financial institutions are black boxes
of risk unlike a lot of other listed firms. What gives the market the insight to value them?
If you believe Mr. Dimon, and I sure
hope you do, senior management at JPMorgan had no idea that the CIO was engaged
in risky trading (instead of hedging), that risk control was ineffective, and
that rogue whales were in London, even apparently when traders at other
institutions publicly pointed out that one JPMC trader was significantly moving
the CDS market.
Mr. Stumpf has testified before the US Congress that he “knew nothing” about creation of bogus accounts, despite employees contacting the bank’s compliance and ethics department and some employees mentioning this is lawsuits filed for wrongful dismissal. Taking their statements at face value and AA knows no reason not to (I’m definitely senior management material), if the CEO with access to inside information doesn’t know, how does the market?
Regulators get to peer into these black
boxes. In the case of large banks in the US they get "invited" (or more accurately invite themselves) to station personnel
inside the box. They get regular detailed
reports on assets, trading positions, and can compel the FI to provide more
information. If so motivated, regulators can meet with bank officers to raise
questions. Even with this access
regulators appear to have trouble regulating banks. What about the market gives it insights
beyond regulators? Or do regulators "see" but
not "see" for other reasons?
The market doesn’t have the same level
and detail of information as regulators nor can it force the FI to give it
more. On what basis does the market form
an opinion? If it is operating on less
than complete information, is its market price more directional than locational? That is, it identifies troubled institutions
but may not have estimated their true value.
If so, then caution has to be used with results based on market values.
By contrast, it’s much easier, but not
easy, to value a manufacturing firm.
These firms generate physical goods whose acceptance by customers can be
tracked. Market share is going up or down.
Margins are increasing or decreasing.
Think of the saga of Blackberry.
But even in these cases, value is directional not locational. That being said, there is always the counter
case, e.g., Sunbeam, where “clever” practices can hide the rot in the
underlying business.
If Theory is
Sound, Make Sure You Have Met the Conditions
Next are questions about the
“market”.
As I understand standard financial theory, there are some requirements for a market. Three guys trading among themselves infrequently is definitely not a market. A market where participants have colluded (think LIBOR, think FX, think …) to “fix” prices in not a market. To the extent that these markets’ prices are inputs into the valuation of securities, then one would have to question the accuracy of price determination of those other securities. Even where markets are not manipulated, they may not meet the test of a real market. In which case their price “discovery” may be wildly inaccurate. It’s no secret that the only true bond market qua market is that for USG securities. Other bonds trade infrequently and in too small numbers to meet the underlying requirement that the market price reflect the outcome of differing views among a multitude of participants. CDS isn’t a real market.
Don’t Push
Theory Beyond Where It Functions
Related to this is pushing an assumed
sound theory too far.
Some years back, a client showed me an analysis he had received from a competitor. It was a masterful piece of mathematics applying the Capital Asset Pricing Model etc. to various countries, showing individual country betas and cost of capital. I don’t remember all of the countries, but do remember that Finland and Bahrain were included. I noted that Nokia was roughly 70% of the value (market capitalization) of the Finnish market and so it seemed to me that the Finnish market was essentially Nokia idiosyncratic risk. Since diversification of idiosyncratic risk is a key requirement for the CAPM etc, application of the theory was "dubious" at best. I expressed doubts that the liquidity of the Bahrain market met the test for a "market". What does a market price mean when there is no or almost no trading?
Look for
Factors that Cause Theory to “Break Down”
But if we do have “real” markets that
can generally estimate prices with reasonable accuracy, can there be factors
that disrupt price discovery?
After JFK was assassinated and after
9-11, the NYSE fell dramatically. For 9-11
it was the largest one day fall since the Great Depression. And the market was
closed until 17 September. While
horrific, these events did not wipe out billions in real value. Liquidity preference, uncertainty, and
outright bed wetting fear drove the market down.
Similarly, there have been markets that imagined value creation e.g., the dotcom boom. The authors recognize this with their conclusion that markets underestimated risk before the GFC. Given that admission, how do we know when to trust the market’s judgment? It was an article of faith at the highest levels of at least one major country’s economic management apparatus that it is impossible to determine the occurrence of a bubble until after it pops. I believe that maestro also held that markets self-regulate away excesses. Views it is clear that worked very very well in theory, but less so in practice.
Are there any factors that could
explain a similar pessimism and divergence from real value today? While the NBER pronounced the GFC ended in
2009, there has not been the usual recovery.
Economic growth is anemic.
Central banks across the world are engaged in unprecedented intervention in financial markets
that some fear is distorting markets and sowing the seeds for future busts. Some are worried that conditions will remain
so weak that unwinding intervention will not be possible without plunging the
world back into GFC2. Markets are
jittery.
As a sector, banks have been
identified as the key culprits responsible for the GFC. Thus, against the general worry about the
economy, banks have pride of place as more risky than other firms. If that weren’t enough to drive perceptions
of bank risk higher, banks have also been repeatedly shown to be (a) apparently ethically
challenged in the conduct of business--not just with respect to mortgage
securities, but Libor rate setting, FX trading, and recently the creation of
dummy customer accounts--and (b) lax or incapable of applying laws relating to
sanctions, money laundering, etc. Some
institutions are serial offenders, “financial recidivists” as Ms. AA calls them. Additionally note that the unprecedented central bank intervention is directly focused on the financial sector and thus on banks.
In some cases, regulatory settlements
have imposed onerous conditions on businesses and hefty fines while only deferring prosecution – leaving that risk “unsettled”. In other cases, settlements have yet to be
reached. In one case regulators have opened
what appears to be public haggling over the size of the fine –not something
that is likely to calm market jitters.
Compliance issues like trading losses
appear all of a sudden. One day
everything is fine the next day the fur hits the fan.
How does one quantify regulatory risk emanating from a "black box"?
In such an environment investors sensibly
would demand higher risk premia. Since
the true risk is unknown and thus unquantifiable, that premium would be
large to cover the unknown. Perhaps larger than necessary?
Investors no doubt are also worried
about the uncertain and potentially unfair results of civil suits, e.g., Arab
Bank and the one against HSBC and several other major EU banks. Something the government has little to no
control over. And the results of which are left to the whims of judges and impartiality of juries.
Are You Conclusions Well Grounded?
Does this mean that bank franchise
values have gone down?
It depends.
It depends on the accuracy of the two
value points being compared.
If the market underestimated risks before the GFC, then the market overestimated pre-GFC franchise values. In this case, how can you make a comparison? But it get worse. Once you accept that the market made a single valuation "mistake", then you've accepted that it can make others. So, why should one have more confidence in the current valuation? Particularly when economic conditions are not "normal": a very anemic recovery and extraordinary central bank policies. Conditions that have obtained for at least eight years despite the NBER's pronouncement.
Nominal and Real Values
While one might compare nominal values, I think that “real” values (to the extent they might be known) would be more important for policy considerations. But it has to be a challenge to untangle multiple factors affecting bank security prices to identify the main driver. Well, at least, it’s hard for AA.
Wrapping Up
At this point, I’ve come back full
circle to where I began: skepticism
about economics and market wisdom/valuations.
Don’t read the above as necessarily
saying that market prices are “rubbish”, but rather that they are not
infallible just as the market is not infallible. A great deal of skepticism, caution, and humility
has to be brought to bear when applying economic or financial theories to the
real world.

Metadiscussion on "Are Big Banks Safer?"

Bank De-Risking Likely to Trump Calls for Financial Inclusion
For Some Activities Risk Avoidance Makes More Sense Than Risk Management |
On September 8th, the Hong Kong Monetary
Authority (HKMA) issued a circular to the CEOs of all Authorized (financial)
Institutions (AIs) in the HKSAR (Hong Kong Special Administrative Region)
entitled “De-risking
and Financial Inclusion”.
The circular sets forth the HKMA’s expectations (read
“instructions”) that AIs adopt a risk based approach (RBA) to implementing
anti-money laundering AML) and countering the financing of terrorism (CFT)
regulations and cease the practice of de-risking, that is refusing to open or
maintain accounts for certain customers.
As outlined below, the HKMA is rowing against some very
powerful tides. The circular is unlikely
to have the stated desired effect.
Some quotes from the circular to set the stage for this
post. I’ve added boldface to highlight
certain points.
Noting the
progressive tightening of AML regulations over recent years the HKMA states “While it is important to ensure that
AML/CFT controls are sufficiently robust and comply with all the relevant
regulatory requirements, the HKMA expects AIs to adopt a risk-based approach
(RBA) and refrain from adopting practices that would result in financial
exclusion, particularly in respect of the need for bona fide businesses to have
access to basic banking services.”
In a similar vein, the HKMA defines “de-risking” as “The phenomenon of banks declining or
discontinuing business relationships with customers or categories of customers to
avoid, rather than manage, the risk involved. “
On the subject of an RBA, the HKMA makes the following
points:
"RBA does not require or expect a “zero failure” outcome. While AIs should take all reasonable measures to identify ML/TF risks at the account opening stage and, for existing customers, on an ongoing basis, it is unrealistic to expect that no ML/TF activities would ever occur through the banking system. AIs are not required to implement overly stringent CDD processes with a view to eliminating, ex-ante, all risks. Otherwise, such an approach would result in a large number of bona fide businesses and individuals not being able to open or maintain accounts. CDD is only one part of an effective AML/CFT regime. AIs are also required to implement a system that can monitor and detect suspicious transactions in order to report them to the relevant authorities and take the necessary mitigating measures, such as enhanced CDD."
"RBA does not require or expect a “zero failure” outcome.

AIs are also required to implement a system that can monitor and detect suspicious transactions in order to report them to the relevant authorities and take the necessary mitigating measures, such as enhanced CDD."
News reports suggest that the HKMA's action was occasioned
by several banks “tossing” existing customers. Bloomberg refers to the alleged abrupt
closure by HSBC of accounts of a long standing client that is an offshore
fund.
That’s borne out in the circular itself which also notes the
refusal of some unnamed FIs in the HKSAR refused to accept new clients or set
“onerous” requirements. See the annex to
the circular.
The
HKMA’s circular follows one issued
in late August by five US regulators
of financial institutions in the country.
Yes, you read that right “five”. Apparently one regulator is insufficient for the USA's financial sector. It's that big! That circular also contained an
appeal for banks to adopt a RBA, but did not include the HKMA’s statement that
it didn’t expect RBA AML/CFT to prevent all illegal transactions. Instead the five US regulators offered the
comforting thought that “the
Treasury and the FBAs do not utilize a zero tolerance philosophy that
mandates the strict imposition of formal enforcement action regardless of
the facts and circumstances of the situation”.
I
trust like AA you find those words comforting in a particularly baffling way. Are these regulators saying that existing
regulations allow them to take formal enforcement action regardless of facts
and circumstances but that they will kindly forbear from exercising these powers?
Instead might they apply strict non formal
enforcement actions? On that score, what is a “strict” imposition and
how does it differ from a “strict” enforcement action? Or are they saying that existing US laws and
regulations are so written that they could impose draconian penalties for a “slip
or two” in compliance? Finally, if the
posture of the regulators is based on a “philosophy” and not the law, could
that “philosophy” change with the next administration? If that’s the case,
should banks be advised to prepare for the worst?
The
widespread use of the US dollar in both commercial and financial transactions
and the propensity of the US to use that position to levy fines and impose
extraterritorial requirements make US regulations and the “philosophy” of the
US regulator of paramount concern to internationally active banks.
The HKMA may have “expectations” but Hong
Kong and other foreign banks are likely to be more sensitive to what the US “expects” as
evidenced by its past behavior. Thus, the HKMA’s appeal is almost certain to collide with
banks’ self-interest and certain “objective conditions”.
First, banks are profit oriented not public service
institutions despite some manifestly absurd industry positioning / brand
development advertising campaigns that are currently running.
In other words, profit is job #1. Financial “inclusion” like charity work is well down the list of priorities. And is a miniscule part of
activities. Thus, despite its ad
campaign running on the Bloomberg TV, Bank of America Merrill Lynch doesn’t
devote a major portion of its efforts to bring clean water to folks in
Africa.
Profit on an account is a function of revenues less costs.
Providing bank accounts and related services is a low margin
high volume business. Contrast that with investment banking transactions where
the volumes are significantly lower but the margins are immense.
Considering only operating costs, many SME accounts at
best offer marginal profitability. We’re talking about maybe tens of
thousands of dollars profit per account for many accounts.
When the costs of customer due diligence, monitoring,
preparing and filing of suspicious transaction reports are included, profit is
even less. Customer due diligence (CDD)
at the inception of a relationship is particularly labor intensive. Much of the subsequent monitoring can be done
via computer programs, but at the end of the day someone has to review the
reports generated, decide whether to investigate further, and ultimately
whether to approach the customer for more information and/or file a suspicious
transaction report STR).
On that score, banks file a good portion of their STRs for
defensive (CYA) reasons. It demonstrates
they have a working compliance system.
If something untoward about a customer turns up in the future, the
bank can say to the regulators “But I reported to you. By the way you never got back to me.” Thus, monitoring “risky” customers taken on
to promote financial inclusion may trigger the need for a CYA STR even if the bank thinks the customer is "clean". One can't be too careful because regulatory hindsight is often more than 20/20.
Fines take a potential bite out of profit. But by increasing expenses they can also affect the capital a bank
is required to maintain for operational risk under the Basel
framework. Lower Basel capital adequacy
ratios can affect credit and stock ratings.
Increasing capital can lead to declines in ROE if the profits do not
cover the cost of capital. If capital
cannot be increased, then the bank may have to reduce certain other activities
(e.g. credit or market risk related) thus reducing income/profit.
Second, it’s important to remember that banks are free to
select or reject customers according to their own criteria. Even in countries that have laws to prevent
discrimination, banks may reject customers as long as the as criteria used are
business principles-based, e.g., risk not race and are consistently applied. Not every applicant for a new loan or new
account will get one. Not every customer
with an existing loan will be granted a renewal or extension. Similarly, not every customer with an account
is guaranteed the right to retain it. So
the appeal is a request not a command.
Third, there are a variety of objective conditions and not
simply bloody-mindedness that are pushing banks to “de-risk”.
Chief among these are regulatory and legal risks, but there
are others.
Regulatory Risks.
Billion dollar fines concentrate the minds or bankers quite
sharply. Settlements with regulators
include more than fines. Often settlements are
(legally) structured as deferred prosecution agreements or DPAs. As the name suggests, the DPA holds a sword
over the head of the financial institution and compel compliance on an
extraterritorial basis.
But don’t take AA’s word for it.
Here are two 2016 quotes attributed to Assistant Attorney General Leslie Caldwell. “[w]e can require
that the banks cooperate with our ongoing investigations, particularly
in our investigations of individuals. We can require that such compliance
programs and cooperation be implemented worldwide, rather than just in
the United States. We can require periodic reporting to a court that
oversees the agreements for its terms.”
Under the right
circumstances, the government “will not hesitate to tear up a DPA or NPA and
file criminal charges, where such action is appropriate and proportional to
the breach.”
Here are some illustrative examples of DPAs. Standard Chartered 2014 with DFS New
York State. The consent order triggered significant de-risking
by SCB in the UAE as you may
recall. Here’s HSBC 2012.
So if you were a financial institution considering opening
or maintaining an account relationship, would one of your key risk mitigation
concerns be avoiding the risk that a regulator could suddenly be dictating how
you run your business worldwide? See
the requirements in the HSBC DPA Paragraph #5. Note
not only the number of requirements but also the short leash in later points Paras 8 and 14-16.
But as they say on late night TV. “Wait there’s more”.
Civil Lawsuits
Lawsuits such as that against the Arab Bank or the one in
progress against HSBC,
Barclays, Standard Chartered, the Royal Bank of Scotland and Credit
Suisse are no doubt worrisome. The latter suit is predicated on these banks’
admission of transferring money for Iran which the plaintiffs assert helped
finance terrorist attacks against US military personnel in Iraq. There is to my
knowledge no assertion that these banks actually transferred money for those
attacks. More here.
Banks might be
forgiven--particularly in light of the Arab Bank case—for questioning whether fair
trials or impartial juries are available in certain jurisdictions.
Both the regulatory
and legal actions highlight what is perhaps the key factor here. Banks are subject not only to their own
regulators and laws but to those of other countries. The primary role of the US dollar in
international financial transactions exposes not only major international banks
but also smaller banks to US enforcement or legal actions.
Staff Risks
International banks operate in many countries. Staff attitudes toward government regulations
vary greatly. In many countries the
population treats their own government's laws and regulations as suggestions rather
than binding constraints. In some countries
as a direct challenge to find a creative workaround.
An even more casual attitude often applies to laws of foreign countries. Bank managements have to deal with the staff
they have not the staff they wish they had.
In which case exposure can be neatly mitigated by not doing certain
types of business or dealing with certain customers. Eliminate discretion and one eliminates potential problems.
Recidivism Risk
If a bank is unfortunate enough to have encountered
enforcement action, a further “slip” could trigger a severe response from at
least one particular country, e.g., “tearing up DPAs” “filing criminal charges”
as AAG Caldwell is quoted above. Or
additional fines or additional business conditions imposed. Or even the threat of such action could cloud
an institution’s stock price, customer confidence, etc. Here’s an
example.
Conclusion
When the risk reward ratio is highly skewed, the most
effective risk management is risk avoidance.
I suppose I could construct an RBA for running with
scissors. But I will forgo running with scissors rather than “managing the risk”
of doing so. Simply because the
potential return is dwarfed by the risk.
Banks are likely to do the same with respect to financial
inclusion. The lesson of Nogales
Arizona and other similar stories of US
banks closing branches on the US-side of the border with Mexico and “tossing” customers may be
illustrative on this point. Banks are
likely to be much less solicitous of foreign than domestic customers. And the solicitude for domestic customers seems minimal in these cases.
As outlined in the above press report, the US banks
apparently claimed that their domestic de-risking was related to revised
regulations requiring additional regulatory reporting and closure of “risky”
accounts. If you close your branch, you
neatly “solve” both problems.

When the Moon is Full All Mankind is One |
Five nut mooncake no egg. AA's favorite.
Mooncake courtesy of one of AA's new colleagues and shipped along with two others at considerable expense.
The other two sent are not pictured as they disappeared rather quickly after the package was opened.
Both AA and Ms. AA pronounced them better than Hong Kong
If there were any hidden messages, they are lost to history. We didn't stop to look.
What is A Lepo?
One Toke Over the Line |
All Hat No Cattle |
There's been a lot of unwarranted piling on Candidate Gary Johnson over his honest but simple question in an interview with MSNBC "What is Aleppo?" Video here.
Many have assumed this reflects a lack of knowledge about geography. Johnson has explained that "he was thinking of an acronym and not the Syrian war."
Does this explanation hold water?
First, the interview was verbal. We really don't know what Candidate Johnson said, "What is Aleppo?" Or "What is a LEPO"? Or "What is a lepo?"
Second are there any terms that he might have been thinking about that could relate to Syria? Drawing on his vast knowledge of matters financial and linguistic, AA offers the following possibilities.
- LEPO Low Exercise Price Option - A financial innovation credited to the Land of Oz. Perhaps, Johnson was trying to clarify if MSNBC was asking for him to provide a low cost option to resolve Syria.
- Lepo - A Basque word for "neck" - a common expression for a kill or choke point. Hence, a request for him to identify the one action that would end the conflict. Why would he be thinking about Basque expressions? Those with some knowledge of US history know that immigrating Basques settled primarily in California and the Southwest of the US. While New Mexico (where Johnson was governor) was not a major destination, Basques did settle there.
- Lepo - A Finnish word for "at rest" used by the Finnish military to mean "at ease". Think of it as a way of conveying "Mission Accomplished" but without using those specific words. Or perhaps a criticism of the current Administration's policy.
On the other hand, perhaps he didn't know. Or in the glare of the spotlight froze.
A worthy nominee for the Rick Perry "statesman" award.
