Title: The Role of Information Failures in the Financial Meltdown
1The Role of Information Failures in the Financial
Meltdown

Berkeley, Summer 2009
2Introduction
- Disclaimer
- Im not a macro-economics expert, but I do know
something about the economics of risk and
uncertainty, and something about markets, market
failure, and appropriate regulatory response. - Overview
- A major source of the meltdown in the financial
markets was the result of information failures
and any solutions that did not address the
information needs would not be viewed as anything
more than holding actions that would eventually
fail. - Each of these attempted fixes only made the
overall situation worse by highlighting what we
still did not know about the underlying
valuations of the assets and derivatives at the
heart of the financial side of the problem.
3Introduction
- Basic points
- Original view was this was primarily a
"financial" crisis. Taking that view, the first
proposed remedy was a bailout of major financial
institutions with some government entity using
taxpayer funds to buy securities of unknown value
from supposedly sophisticated money managers. - Instead we needed to both understand the scope of
the problem (not just financial assets) and the
underlying causes. To start, the focus should
have been - to resolve the information problems to help
evaluate the suspect securities - to assist in the renegotiation of mortgages to
help keep homeowners in their houses.

5Background on Banking (Banks, Near-banks, etc.)
- Banks and other financial institutions used to
hold assetssome cash, real estate, securities,
and the loans they made to their customers. - Some still do, butfor the most partthey now are
in the business of earning fees for originating
loans, buying and selling obligations of one sort
or another, etc. - On the other side of the ledger, the liabilities
of the financial institutions are the sums they
owe othersthe depositors in commercial banks and
SLs, and frequently the deposits of other
institutions as well as government agencies. - The basic principle of banking was to know the
value of ones assets and liabilities, accurately
disclosing this to regulators and the public.
6Background on Banking -- Changes in the Industry
- As the business of banking became more fee-based,
the functions of loan origination, loan
processing, and asset management became more
separable. - Home buyers no longer dealt with a local bank
that would be expected to hold and process their
loan into the future. Banks provided consumer
credit, via credit cards, homeowners lines of
credit, and so on, but again often did not hold
onto the asset. - So long as the packaging and re-packaging of
these assets (loans) into financial instruments
was done in a transparent fashion, the result was
mostly positive.
7Background on Banking Changes in the Industry
- The major loss from this change was the lack of a
personal relationship with ones banker, who
was frequently a respected member of the local
community. - There were gains in this system as loanable funds
could more easily flow to growing regions and
industries, and the entry of non-bank financial
institutions into some parts of the market
provided competition that reduced costs and
eliminated pockets of discrimination. - Near banks and non-bank banks became common,
and regulation was lax.
8Background on Mortgages
- An old-fashion fixed-rate mortgage was typically
- 30-year loan on a single-family, owner-occupied,
primary residence - For a fixed annual percentage rate
- Held by the lender (traditionally a local bank or
SL) - and therefore had reasonable fees (points)
9Background on Mortgages
- Remember that banking became more fee-based, so
lender and loan processor were not always the
same entity. - Specialized lenders emerged (e.g., Countrywide)
- Two channels for loan origination
- Lenders sales organizations
- Mortgage brokers
10Mortgages mortgage packages became more complex
- Even simple variable rate mortgages (ARMs)
require one to understand - Basis for the rate (the index)
- The margin (mortgage rate index rate)
- When it can be reset
- Caps
- Negative amortization possibilities
- In 2004, then FRB Chair Greenspan argued that
ARMs were under-utilized and the reliance on
traditional fixed rate loans was costing home
buyers money. While the second part was
technically correct, it ignored the increased
risk to both borrowers and society of an
increased reliance on variable-rate products.
(Speech to the Credit Union National Association,
February 23, 2004) .
11Mortgages mortgage packages became more complex
- And then there were even more complex versions
- GPARMs (Gip-ims)
- Hybrid ARMs, interest-only ARMs, payment-option
ARMs, etc. - Consider the result of a complex, no-doc mortgage
on a home with an inflated appraisal. The
outcome is that the underlying value of the
property is unknown, the credit-worthiness of the
borrower is unknown, and the precise terms of the
loan and the stream of payments are also unknown.
This is the exact opposite of how a reasonable
credit market should operate.
12Mortgages What is the extent of the problem?
- Current mortgage delinquency rates (July 2009)
- 6.8 of non-agency prime mortgages
- 21 of Alt-A mortgages
- 40 of sub-prime mortgages
Source Fitch Ratings, as reported in Brett
Arends, Should You Invest In Toxic Assets?,
WSJ, July 29, 2009
13Pay-option ARMs at Countrywide (1)
- Both Mozilo and Sambol were aware as early as
June 2006 that a significant percentage of
borrowers who were taking out stated income loans
were engaged in mortgage fraud. On June 1, 2006,
Mozilo advised Sambol in an email that he had
become aware that the Pay-Option ARM portfolio
was largely underwritten on a reduced
documentation basis and that there was evidence
that borrowers were lying about their income in
the application process. On June 2, 2006, Sambol
received an email reporting on the results of a
quality control audit at Countrywide Bank that
showed that 50 of the stated income loans
audited by the bank showed a variance in income
from the borrowers IRS filings of greater than
10. Of those, 69 had an income variance of
greater than 50. These material facts were never
disclosed to investors. - SEC Complaint, SEC v. Mozilo, Sambol Sieracki,
CV09-03994, filed June 4, 2009
14Pay-option ARMs at Countrywide (2)
- On June 1, 2006, one day after he gave a speech
publicly praising Pay-Option ARMs, Mozilo sent an
email to Sambol and other executives, in which he
expressed concern that the majority of the
Pay-Option ARM loans were originated based upon
stated income, and that there was evidence of
borrowers misrepresenting their income. - Mozilo met with Sambol the morning of September
25, 2006 to discuss the Pay-Option ARM loan
portfolio. The next day Mozilo sent an e-mail to
Sambol and Sieracki expressing even greater
concern about the portfolio. In that e-mail,
Mozilo wrote we have no way, with any
reasonable certainty, to assess the real risk of
holding these loans on our balance sheet. ... The
bottom line is that we are flying blind on how
these loans will perform in a stressed
environment of higher unemployment, reduced
values and slowing home sales. - SEC Complaint, SEC v. Mozilo, Sambol Sieracki,
CV09-03994, filed June 4, 2009
15The Placid Mortgage case (from John Grishams The
Associate)
- Starting in 2001, when a new wave of government
regulators took over and adopted a less intrusive
attitude, Placid and other huge home mortgage
companies became aggressive in their pursuit of
new loans. They advertised heavily, especially on
the Internet, and convinced millions of lower-
and middle-class Americans they could indeed
afford to buy homes that they actually could not
afford. The bait was the old adjustable-rate
mortgages, and in the hands of crooks like Placid
it was adjusted in ways never before imagined.
Placid sucked them in, went light on the
paperwork, collected nice fees up front, then
sold the crap in the secondary markets. (pp.
152-153)
16Packaging Mortgages
- Secondary markets Packages of loans had been
sold to investors for years (e.g. via GNMA) - Computerization made it even easier to track
these. - But it also made it easier for the packages to
become more complex.

17Background on Derivatives
- Derivatives can be economically useful
- Provide flexibility to buyers/sellers
(lenders/borrowers) - Their value depends on the value of the
underlying assets (claims) - But the asset values themselves can be uncertain
(hence there is risk) - Derivatives can range from relatively simple to
incredibly complex - Therefore, derivatives can be good or bad
depending on the circumstances - Linkage to underlying assets STRIPS GNMA
obligations are very direct (so much so that some
do not consider them to be derivatives). - I probably should refrain from making simplistic
value judgments, but I wont. But there are a
number of unstated caveats and qualifications to
much of what follows. - Im not the only one using this terminology bad
assets, bad bank, etc.
18A Good Derivative
- First, a relatively simple example with little or
no risk STRIPS - STRIPS is the acronym for Separate Trading of
Registered Interest and Principal of Securities. - STRIPS let investors hold and trade the
individual interest and principal components of
eligible Treasury notes and bonds as separate
securities. - STRIPS are popular with investors who want to
receive a known payment on a specific future
date. - STRIPS are called zero-coupon securities. The
only time an investor receives a payment from
STRIPS is at maturity. - STRIPS are not issued or sold directly to
investors. STRIPS can be purchased and held only
through financial institutions and government
securities brokers and dealers.

tables/strips/strips.htm
19More on STRIPS
- In the old days a bond was a combination of
return of principal and coupons (usually one
every 6 months)
- Now they are all electronic entries
20More on STRIPS
- A financial intermediary (bank, brokerage house,
etc.) would combine various coupons from a number
of bonds so that an investor could find the
maturity and rate of return desired independent
of what the borrower had originally offered. - It was a straight-forward operation to determine
the value with a computer. - Also, there was no physical coupon as such,
just the computer entry. - The intermediary charged a small fee to record
and manage the transactions.
21A Bad Derivative - 1
- Tom Wolfes Giscard (from Bonfire of the
Vanities, 1987) - The (fictional) Giscard Bond, issued by the
French government, had coupons and maturity value
linked to the French Franc value of a fixed
weight of gold. - So as the price of gold when up and down, so did
the value of the Giscard. (p. 65) - The only real problem was the complexity of the
whole thing. (Ibid.)
22Bad Derivative - 2
- Simply put derivatives are the weapon of choice
for gaming the system.Derivatives provide a
means for obtaining a leveraged position without
explicit financing or capital outlay and for
taking risk off-balance sheet, where it is not as
readily observed and monitored.Viewed in an
uncharitable light derivatives and swaps can be
thought of as vehicles for gambling they are,
after all, side bets on the market. - --Richard Bookstaber, author of A Demon of Our
Own Design, in congressional testimony.
23Bad Derivative - 3
- Even when derivatives do allow financial risks
to be transferred, that is not always a good
thing. John Kay, a leading Scottish economist,
noted recently that he used to teach along with
most other economics professors that
derivatives allowed risks to be transferred to
those better able to bear them. But, he added,
experience had shown that to be wrong. Now, he
said, he teaches that derivatives allow risk to
be shifted from those who understand it a little
to those who do not understand it at all. - --Floyd Norris, New York Times, June 25, 2009.
24Uncertain Derivatives -- You decide whether
they are good or bad
- Other examples of derivatives
- Puts, calls, stock options
- SDRs, ECUs (pre-Euro bundles of currencies)
- Commodity futures
25CMOs Combining Mortgagesand Derivatives
- Collateralized mortgage obligations (CMOs) are
bonds based on home mortgages with a twist that
the bonds are categorized into different tranches
to redistribute the risk of mortgage prepayment
and mortgage default. - Tranche is French for slice, and is used in
finance to refer to one portion of a group of
related securities. - More generally, CDO (Debt)
26CDOs Combining Mortgagesand Derivatives
- Why some CDOs are probably worth ZERO
- Higher yield tranches have higher risk (this
should not be a big surprise to anyone)
27CDOs A Special Purpose EntityInitial condition
Assuming 3 tranchesEquity tranche Medium-risk
tranche Low-risk tranche
Assets
Liabilities
Calculation area 8.0 mil -2.5 mil -2.4

represent)

30Background on Insurance
- To prevent insurance from being little more than
gambling, one needs to have an insurable
interest - The cost of insurance is
- (The probability of the loss) x (the expected
amount of the loss) - Plus a risk premium
- Possibly plus any transactions costs
31More on Insurable Interest
- (From an economist who is a fan of murder
mysteries) - To prevent (additional) incentives to murder, one
can not buy a life insurance policy on a
stranger. You can purchase insurance on a
relative, a business partner, etc. - This has been the plot device in a number of
mysteries (often in the form of a tontine). - R. L .Stevenson, The Wrong Box
- A. Christie, 450 from Paddington Station
- And, of course most famously, The Simpsons.
- Similar rules for other types of insurance
32More on Insurable Interest (actually a digression
on the importance of The Simpsons in modern
culture)
- Grampa and Mr. Burns enter into a tontine during
World War II, involving a treasure of antique
paintings stolen from a German castle. When the
two of them become the only surviving members,
they compete for the rights to the prize.
Eventually they both lose once the US State
Department interferes and takes the paintings
back to the German baron who is the rightful
owner. (From Wikipedia entry for tontine.)
Season 7, episode 22 "Raging Abe Simpson and His
Grumbling Grandson in The Curse of the Flying
Hellfish. Originally aired April 28, 1996.
33Insurancethe Good and the Bad
- Again, the good and the bad, but this time
with the uncertain - Good Life insurance, car insurance, maritime
insurance, etc. - Bad Tontines, bucket shops, sports betting
(?) - Uncertain Credit default swaps
34Bucket shops
- Formally, a bucket shop is a firm that books"
(i.e., takes the opposite side of) retail
customer orders without actually having them
executed on an exchange. - From the Financial Times
- The bank panic of 1907 is remembered for J.P.
Morgan forcing all the bankers to stay in a room
until they agreed to contribute to fixing the
crisis. What has been forgotten is one major
cause of the crisis unregulated speculation on
the prices of securities by people who did not
own them. These betting parlours, or fake
exchanges, were called bucket shops because the
bets were literally placed in buckets. The states
responded in 1908 by passing anti-bucket shop and
gambling laws, outlawing the activity that helped
to ruin that economy. (March 30, 2009) - These laws were pre-empted by the Commodity
Futures Modernization Act of 2000.
35What is a Credit Default Swap?
- A contract between two parties, in which one
party makes periodic payments, while the other
agrees to pay a sum of money if a certain event
occurs. A CDS takes place in the world of
financial markets, and the "event" that triggers
the payoff is when a credit instrument, such as a
bond or loan, goes into default. - Investors use CDSs primarily for two reasons
- as an insurance vehicle to hedge an investment in
a company - as a gambling mechanism to make a profit if the
company fails.
36Credit Default Swap valuation
- CDS pricing The spread is an annual amount that
the buyer must pay to the provider of the CDS
over the length of the contract, expressed as a
percentage of the notional amount. This is very
much like the premium paid in insurance. In
general, a company with a higher CDS spread is
considered more likely to default by the market,
and a higher fee would be charged to protect
against this happening. - Other valuation issues the length of the
contract, the amount of protection, health of
the issuer (as well as of the covered entity). - Partial payments (to counter-parties) required
as underlying conditions change.
37Credit Default Swap markets
- No organized exchange therefore, no clear
understanding of amount outstanding. - Gretchen Morgenson estimated 30 billion
outstanding in Jan. 2009. - Some estimate that as much as 90 were not used
for hedges. - But there may have been offsets included in this
estimate.

38Background on Ratings Agencies
- Standard Poors, Moodys Fitch
- If the ratings agencies had done a better job,
we wouldnt be having this conversation. Larry
White (NYU), on NPR Planet Money, June 5, 2009.
39Bailout measures that did not work (and why)
- Banks
- Original plan to take bad assets off the
booksno credible way to value them - Preferred stockviewed as just another obligation
- Stress tests
- Odd assumptions about revenue projections, etc.
(WSJ, May 28, 2009) - As of June 5, 2009, it appears as though even the
FDIC does not accept the results.
40Bailout measures that did not work (and why)
- More on the too big to fail logic
- Size political power (even noticed by the WSJ)
- Congress Helped Banks Defang Key Rule (June 3,
2009) about mark-to-market and Banks Try to
Stiff-Arm New Rule (June 4, 2009) off-balance
sheet accounting - Secret Sanctions (WSJ, July 17, 2009)
- Bank of America Corp. is operating under a
secret regulatory sanction that requires it to
overhaul its board and address perceived problems
with risk and liquidity management, according to
people familiar with the situation. Citigroup
Inc. has been operating since last year under a
similar order with the Office of the Comptroller
of the Currency, according to people familiar
with the matter. The company recently has been
negotiating with the Federal Deposit Insurance
Corp. about entering into a similar agreement
with that agency, these people say. Spokesmen
for Citigroup and the FDIC declined to comment.
41Bailout measures that did not work (and why)
- Mortgages
- Refinance plans too small, poorly implemented
- 17,000 loans modified through May 31, 2009 (NPR)
- Some 9 of eligible borrowers have received
trial modifications under the Obama
administration's ambitious effort to help
struggling homeowners, according to data released
by the Treasury Department on Aug. 4,
2009.Maya Jackson Randall Jessica Holzer,
WSJ - Ignored differing incentives of originators,
servicers, and holders of loans - Exacerbated by revision of mark-to-market rule
- (technical digression needed here)
42Bailout measures that did not work (and why)
- Mortgages
- Confounded by second mortgages and homeowner
lines of credit (HLOC) - Second mortgages HLOC are profitable for
lenders. But they are subordinate to first
mortgages. If a lender and borrower want to
re-negotiate a first, they may need the holder of
the second (or HLOC) to also take a write-down in
order for the borrower to afford the revised
first. - Recognizing this, the book value of the second
should be reduced, forcing the bank to incur
additional losses. - Lesson Mark-to-market rules really do matter.
43Credit Default Swap markets (1)
- Proposed solutions
- Buyers should take the hit.
- If you live in a house and you dont buy
reputable insurance and a fire burns it down,
its your fault. - Unwind the contracts (inversion)
- Insurance premiums would be refunded to buyers of
credit protection from the entity that wrote the
initial contract. And the seller would no longer
be under any obligation to pay if a default
occurred. The premium repayments would be made
over the same period and at the same rate that
they were paid out. If a contract was struck
three years ago and charged quarterly premiums,
the premiums would then be refunded quarterly
over the next three years. - Counter argument from an insider Unwinding CDS
would harm the integrity of financial market.
Kind of like if I place a bet with a bookie that
doesn't pay, the bookie can't pick and choose
after the fact which games he wants to payout on
and which he wants to cancel. Not without risking
have customers fleeing.
44Credit Default Swap markets (2)
- Proposed solutions (continued)
- Use bailout funds to pay counter-parties.
- (Longer-term) Create exchange(s) or
clearinghouse(s), regulator, reserve
requirements. - Worry about the exemptions!
45Credit Default Swap markets (3)
- CDS what we actually did (difficult to
document) - AIG loans at 18 p.a.
- Possible rationales hide transfers to
counter-parties, especially foreign banks
institutions prop up insurance subsidiaries - Bear Stearns guaranteed contracts
- J. P. Morgan ----------------
CW (early July 2009) Actually, these last two
seem to have worked reasonably well, at least
when compared to the AIG bailout. But were they
worth the cost?
CW (late July 2009) The dozens of insurance
companies that make up AIG show signs of
considerable weakness even after their corporate
parent got the biggest bailout in history, a
review of state regulatory filings shows. NY
Times, July 30, 2009
46Proposed measures that probably will not work
(and why)
- Use Treasury/Fed funds to assist private entities
to buy troubled assets - (I guess) the theory is that if one only has to
put up (say) 5-20 of the purchase price, the
correct valuation isnt too much of an issue. - But this leads to its own set of strange
incentives - Some banks are prodding the government to let
them use public money to help buy troubled assets
from the banks themselves. Banking trade groups
are lobbying the Federal Deposit Insurance Corp.
for permission to bid on the same assets that the
banks would put up for sale as part of the
government's Public Private Investment Program. - PPIP was hatched by the Obama administration as a
way for banks to sell hard-to-value loans and
securities to private investors, who would get
financial aid as an enticement to help them
unclog bank balance sheets. The program, expected
to start this summer, will get as much as 100
billion in taxpayer-funded capital. That could
increase to more than 500 billion in purchasing
power with participation from private investors
and FDIC financing. (WSJ, May 27, 2009)
47What is wrong with letting the banks be both
buyers and sellers of toxic assets?
- Some critics see the proposal as an example of
banks trying to profit through financial
engineering at taxpayer expense, because the
government would subsidize the asset purchases. - "To allow the government to finance an
off-balance-sheet maneuver that claims to shift
risk off the parent firm's books but really
doesn't offload it is highly problematic," said
Arthur Levitt, a former Securities and Exchange
Commission chairman who is an adviser to
private-equity firm Carlyle Group LLC. - "The notion of banks doing this is incongruent
with the original purpose of the PPIP and wrought
with major conflicts," said Thomas Priore,
president of ICP Capital. - One risk is that certain hard-to-value assets
mightn't be fairly priced if banks are
essentially negotiating with themselves. Inflated
prices could result in the government overpaying.
Recipients of taxpayer-funded capital infusions
under the Troubled Asset Relief Program also
could use those funds to buy their own loans.
(WSJ, May 27, 2009)
48Proposed measures that probably will not work
(and why)
- CDS or derivatives clearinghouse
- Too many possible exemptions
- Profits for the custom CDS are much higher than
for the plain vanilla ones - There are a number of facilitators and
intermediaries, all of whom make large fees - Intermediaries will be on the hook and someone
has to insure and/or regulate them - ICE Trust (in NYC) wants this business
- CDS contracts are inherently easy to manipulate
- WSJ, June 11, 2009
49Proposed measures that probably will not work
(and why)
- Create database to help evaluate mortgages and
ABS - To deal with the problem, issuers of
asset-backed securities should provide extensive
detail in a uniform format about the composition
of the original pools and their subsequent
structure and performance, whether they were sold
as SEC-registered offerings or private
placements. By creating a centralized database
with this information, the pricing process for
the toxic assets becomes possible. Making such a
database a reality will restart private
securitization markets and will do more for the
recovery of the economy than yet another redesign
of administrative agency structures.(Ken Scott
John Taylor, WSJ, July 21, 2009) - Insufficient data are collected on individual
loans, and often the data are of questionable
accuracy or timeliness, so the analysis of
mortgages and other types of loans which have
been sliced and diced through multiple levels of
securitization will be subject to substantial
error. Accordingly, the valuation of such ABS
will be highly suspect, even if the data reside
in a centralized databaseRather than using
securitization to shift individual loans toward
their funding source, public policy should seek
to encourage lenders to retain ownership of the
loans they make.(Bert Ely, WSJ, July 27, 2009)
50Proposed measures that probably will not work
(and why)
- Current proposal to overhaul financial regulation
- (See earlier slide on political power of
financial institutions) - Suspicion of giving the FRB more power
- Treasury Secretary Timothy Geithner blasted top
U.S. financial regulators in an expletive-laced
critique last Friday as frustration grows over
the Obama administration's faltering plan to
overhaul U.S. financial regulation, according to
people familiar with the meeting.The proposed
regulatory revamp is one of President Barack
Obama's top domestic priorities. But since it was
unveiled in June, the plan has been criticized by
the financial-services industry, as well as by
financial regulators wary of encroachment on
their turf.Mr. Geithner, without singling out
officials, raised concerns about regulators who
questioned the wisdom of giving the Federal
Reserve more power to oversee the financial
system. Ms. Schapiro SEC and Ms. Bair FDIC,
among others, have argued that more authority
should be shared among a council of regulators.
WSJ, Aug. 4, 2009 - Need more specific guidance!
51Summary or Conclusions
- More disclosure needed
- Off balance sheet entries
- Nature of CDS and derivatives
- Property and asset (re)valuations
- Strong mark-to-market rules
- Other options
- Return to traditional banking (at least in part)
- Improved regulatory system
- Systemic regulator
52Summary or Conclusions
- Certainly confidence is crucial to the open and
fair operating of markets. Bailouts did not
build confidence. What confidence is created by
is a clarity of the problem. - Interview with Gretchen Morgenson on NPRs Fresh
Air, June 9, 2009
