Why 2010 will be Challenging for Goldman Sachs

December 30, 2009

I figured I’d let 2009 go out with a bang and post another of my contrarian views: 2010 will be rough for Goldman Sachs. Why? Well, to know the answer to that, you should head on over to the Huffington Post where the full piece is online.

Happy New Year!

Notes and Predictions: The Stress Test

May 6, 2009

As the results of the stress test start leaking out slowly, it’s a fun exercise to make some educated guesses/predictions about what the future holds and take note of pertinent facts. As we’ve discussed before, there is a lot to take issue with when considering the results of the stress test at all, especially given the added layers of uncertainty stemming form the limited information provided in the scenarios. So, without further delay, let’s get started.

1. The baseline scenario will prove wholly inadequate as a “stress test.” Please, follow along with me as I read from the methodology (pdf).  I’ll start with the most egregious and reckless component of the mis-named baseline scenario (I would rename it the, “if payer works” scenario) : what I will refer to as “the dreaded footnote six.” From the document:

As noted above, BHCs [(Bank Holding Companies, or the firms being stress tested)] with trading account assets exceeding $100 billion as of December 31, 2008 were asked to provide projections of trading related losses for the more adverse scenario, including losses from counterparty credit risk exposures, including potential counterparty defaults, and credit valuation adjustments taken against exposures to counterparties whose probability of default would be expected to increase in the adverse scenario.(6)

[…]

(6) Under the baseline scenario, BHCs were instructed to assume no further losses beyond current marks.

(Emphasis mine.)

Holy <expletive>! In what alternate/parallel/baby/branching universe is this indicative of anything at all? Assume no further losses beyond current marks? Why not assume everything returns to par? Oh, well, that actually was a pretty valid assumption for the baseline scenario. From the document:

New FASB guidance on fair value measurements and impairments was issued on April 9, 2009, after the commencement of the [stress test].  For the baseline scenario supervisors considered firms’ resubmissions that incorporated the new guidance.

(Emphasis mine.)

Thank goodness! I was worried that the “if prayer works” scenario might have some parts that were worth looking at. Thankfully, for troubled banks, I can skip this entire section. (Confidence: 99.9999%)

2. Trading losses will be significantly understated across all five institutions that will need to report them. First, only institutions with over $100 billion in trading assets were asked to stress their trading positions. Second, from the section on “Trading Portfolio Losses” from the document:

Losses in the trading portfolio were evaluated by applying market stress factors … based on the actual market movements that occurred over the stress horizon (June 30 to December 31, 2008).

(Emphasis mine.)

Okay, well, that seems reasonable, right? Hmmmm… Let’s take a look. Here is what some indicative spread movements for fixed income products looked like January 9th of 2009, according to Markit (who has made it nearly impossible to find historical data for their indices, so I’m resorting to cutting and pasting images directly–all images are from their site):

(Click on the picture for a larger version.)

Well, looks like a big move is taken into account by using this time horizon. Clearly this should provide a reasonable benchmark for the stress test results, right? Well, maybe not.

currentgraph

(Click on the picture for a larger version.)

Yes, that’s right, we’ve undergone, for sub-prime securities a massive widening during 2009 already. Also, as far as I can tell, the tests are being run starting from the December 2008 balance sheet for each company. So, if I’m correct, for the harsher scenario, trading losses will be taken on December 2008 trading positions using December 2008 prices and applying June 2008 to December 2008 market movements. For sub-prime, it seems pretty clear that most securities would be written up (June 2008 Spread: ~200, December 2008 Spread: ~1000, Delta: ~800, Current Spread: ~2600, December 2008 to Today Delta: ~1600, Result: firms would take, from December 2008 levels, half the markdown they have already taken).

Also, it should be a shock to absolutely no one that most trading assets will undergo a lagged version of this same decline. Commercial mortgages and corporate securities rely on how firms actually perform. Consumer-facing firms, as unemployment rises, the economy worsens and consumption declines, and consumers default, will see a lagged deterioration that will appear in corporate defaults and small businesses shuttering–both of these will lead to commercial mortgages souring.  Indeed we’ve seen Moody’s benchmark report on commercial real estate register a massive deterioration in fundamentals. That doesn’t even take into account large, exogenous events in the sector. Likewise, we see consistently dire predictions in corporate credit research reports that only point to rising defaults 2009 and 2010.

In short, for all securities, it seems clear that using data from 2H2008 and applying those movements to December 2008 balance sheets should produce conservative, if not ridiculously understated loss assumptions. (Confidence: 90%)

3. Bank of America will have to go back to the government. This, likely, will be the end of Ken Lewis. It’s not at all clear that Bank of America even understands what’s going on. First, if I’m correctly reading Bank of America’s first quarter earnings information, the firm has around $69 billion in tangible common equity. Also, it should be noted that the FT is reporting that Bank of America has to raise nearly $34 billion.  Now, with all this in mind, let’s trace some totally nonsensical statements that, unlike any other examples in recent memory, were not attributed to anonymous sources (from the NYT article cited above):

The government has told Bank of America it needs $33.9 billion in capital to withstand any worsening of the economic downturn, according to an executive at the bank. […]

But J. Steele Alphin, the bank’s chief administrative officer, said Bank of America would have plenty of options to raise the capital on its own before it would have to convert any of the taxpayer money into common stock. […]

“We’re not happy about it because it’s still a big number,” Mr. Alphin said. “We think it should be a bit less at the end of the day.” […]

Regulators have told the banks that the common shares would bolster their “tangible common equity,” a measure of capital that places greater emphasis on the resources that a bank has at its disposal than the more traditional measure of “Tier 1” capital. […]

Mr. Alphin noted that the $34 billion figure is well below the $45 billion in capital that the government has already allocated to the bank, although he said the bank has plenty of options to raise the capital on its own.

“There are several ways to deal with this,” Mr. Alphin said. “The company is very healthy.”

Bank executives estimate that the company will generate $30 billion a year in income, once a normal environment returns. […]

Mr. Alphin said since the government figure is less than the $45 billion provided to Bank of America, the bank will now start looking at ways of repaying the $11 billion difference over time to the government.

(Emphasis mine.)

Right around the time you read the first bolded statement, you should have started to become dizzy and pass out. When you came to, you saw that the chief administrative officer, who I doubt was supposed to speak on this matter (especially in advance of the actual results), saying that a bank with $69 billion in capital would be refunding $11 billion of the $45 billion  in capital it has already received because they only need $34 billion in capital total. Huh? Nevermind that the Times should have caught this odd discrepancy, but if this is the P.R. face the bank wants to put on, they are screwed.

Now, trying to deal with what little substance there is in the article, along with the FT piece, it seems pretty clear that, if Bank of America needs $34 billion in additional capital, there is no way to get it without converting preferred shares to common shares. There is mention of raising $8 billion from a sale of a stake in the China Construction Bank (why are they selling things if they are net positive $11 billion, I don’t know). That leaves $26 billion. Well, I’m glad that “once a normal environment returns” Bank of America can generate $30 billion in income (Does all of that fall to T.C.E.? I doubt it, but I have no idea). However, over the past four quarters, Bank of America has added just $17 billion in capital… I will remind everyone that this timeframe spans both T.A.R.P. and an additional $45 billion in capital being injected into the flailing bank. Also, who is going to buy into a Bank of America equity offering now? Especially $26 billion of equity! If a troubled bank can raise this amount of equity in the current environment, then the credit crisis is over! Rejoice!

I just don’t see how Bank of America can fill this hole and not get the government to “bail it out” with a conversion. The fact that Bank of America argued the results of the test, frankly, bolsters this point of view. Further, this has been talked about as an event that requires a management change, hence my comment on Lewis.  (Confidence: 80% that the government has to convert to get Bank of America to “well capitalized” status)

Notes/Odds and Ends:

1. I have no idea what happened with the NY Times story about the results of the “Stress Test.” The WSJ and FT are on the same page, but there could be something subtle that I’m misunderstanding or not picking up correctly. Absent this, my comments stand. (Also, if might have been mean.unfair of me to pick on the content of that article.)

2. The next phases of the credit crisis are likely to stress bank balance sheets a lot more. The average bank doesn’t have huge trading books. However, they do have consumer-facing loan and credit products in addition to corporate loans and real estate exposure. In the coming months, we’ll see an increase in credit card delinquencies. Following that, we’ll see more consumer defaults and corporations’ bottom line being hurt from the declining fundamentals of the consumer balance sheet. This will cause corporate defaults. Corporate defaults and consumer defaults will cause commercial real estate to decline as well. The chain of events is just beginning. Which leads me to…

3. Banks will be stuck, unable to lend, for a long time. I owe John Hempton for this insight. In short, originations require capital. Capital, as we see, is in short supply and needed to cover losses for the foreseeable future. Hence, with a huge pipeline of losses developing and banks already in need of capital, there is likely not going to be any other lending going on for a while. This means banks’ ability to generate more revenue/earnings is going to be severely handicapped as sour loans make up a larger and larger percentage of their portfolios.

4. From what I’ve read, it seems that the actual Citi number, for capital to be raised, is between $6 billion and $10 billion. This puts their capital needs at $15 billion to $19 billion, since they are selling assets to raise around $9 billion, which is counted when considering the amount of capital that needs to be raised (according to various news stories). Interestingly, this is 44% to 55% of Bank of America’s needed capital. This paints a very different picture of the relative health of these two firms than the “common wisdom” does. Granted, this includes a partial conversion of Citi’s preferred equity to common equity.

5. I see a huge correlation between under-performing portfolios and a bank trying to negotiate it’s required capital lower by “appealing” the stress test’s assessment of likely losses in both the baseline and adverse scenarios. As I’ve talked about before, not all portfolio performance is created equal. Citi has seen an increasing (and accelerating) trend in delinquencies while JP Morgan has seen it’s portfolio stabilize. So, for the less-healthy banks to argue their losses are overstated by regulators, they are doubly wrong. It’ll be interesting to see how this plays out–for example, if JP Morgan’s credit card portfolio assumes better or worse performance than Citi and Bank of America.

Repaying T.A.R.P.: There Are Restrictions

April 21, 2009

There is a meme (did you know that word was invented by Richard Dawkins?) going around the blogosphere that, in essence, says Geithner doesn’t have the right to prevent T.A.R.P. repayment, even if no fresh capital is raised. This is incorrect. From the Goldman Sachs T.A.R.P. agreements [pdf!] governing the capital infusion (it’s hidden on the site, but there!):

tarpcovenant

(Emphasis [yes, that’s the green underlining] mine.)

Seems, then, that it’s pretty clear. Whole or partial payments, once allowed by a regulator, require fresh equity raised from a “Qualified Equity Offering.” This is a defined term, and the document defines it as follows:

equityoffering

So, it seems pretty cleat that there are conditions. Now, maybe these aren’t the systemic considerations, but that’s likely why the regulatory approval is required, especially in conjunction with the “stress test,” which we’ve discussed here at length.

Citi’s Earnings: Even Cittier Than You Think

April 20, 2009

Well, Citi reported earnings this past week. And, as many of you know, there are a few reasons you’ve heard to be skeptical that this was any sort of good news. However, there are a few reasons you probably haven’t heard… (oh, and my past issues on poor disclosure are just as annoying here)

On Revenue Generation: First, here are some numbers from Citi’s earnings report and presentation, Goldman’s earnings report, and JP Morgan’s earnings report:

Revenues from 1Q09 Earnings Reports

These numbers should bother Citi shareholders. Ignoring the 1Q08 numbers, Citi–whose global business is much larger and much more diverse than it’s rivals–generates no more, if not slightly less, revenue than the domestically focused JP Morgan and much, much less than Goldman. But it gets worse. Goldman’s balance sheet was $925 billion vs. Citi’s $1.06 trillion in assets within it’s investment banking businesses, roughly 10% larger.  I’d compare JP Morgan, but they provide a shamefully small amount of information. As an entire franchise, however, Citi was able to generate their headline number: $24.8 billion in revenue, on assets of $1.822 trillion. JP Morgan, as a whole, was able to generate $26.9 billion, on assets of $2.079 trillion. JP Morgan, then is 14% larger, by assets, and generstes 8% higher revenue.

These numbers should be disconcerting to Citi, it’s no better at revenue generation than it’s rivals, despite having a larger business in higher growth, higher margin markets. Further, in an environment rife with opportunity (Goldman’s results support this view, and anecdotal support is strong), Citi was totally unable to leverage any aspect of it’s business to get standout results… and we’re only talking about revenue! Forget it’s cost issues, impairments and other charges as it disposes assets, etc.

On The Magical Disappearing Writedowns: Even more amazing is the lack of writedowns. However, this isn’t because there aren’t any. JP Morgan had writedowns of, approximately, $900 million (hard to tell, because they disclose little in the way of details). Goldman had approximately $2 billion in writedowns (half from mortgages). Citi topped these with $3.5 billion in writedowns on sub-prime alone (although they claim only $2.2 billion in writedowns, which seems inconsistent). But, that isn’t close to the whole story. Last quarter, in what I could find almost no commentary on during the last conference call and almost nothing written about in filings or press releases, Citi moved $64 billion in assets from the “Available-for-sale and non-marketable equity securities” line item to the “Held-to-maturity” line item. In fact, $10.6 billion of the $12.5 billion in Alt-A mortgage exposure is in these, non–mark-to-market accounts. There was only $500 million in writedowns on this entire portfolio, surprise! Oh, and the non–mark-to-market accounts carry prices that are 11 points higher (58% of face versus 47% of face). What other crap is hiding from the light? $16.1 billion out of $16.2 billion total in S.I.V. exposure, $5.6 billion out of $8.5 billion total in Auction Rate Securities exposure, $8.4 billion out of $9.5 billion total in “Highly Leveraged Finance Commitments,” and, seemingly, $25.8 billion out of $36.1 billion in commercial real estate (hard to tell because their numbers aren’t clear), are all sitting in accounts that are no longer subject to writedowns based on fluctuations in market value, unlike their competitors. These are mostly assets managed off the trading desk, but marked according to different rules than traded assets. If one doesn’t have to mark their assets, then having no writedowns makes sense.

On The Not-so-friendly Trend: This is a situation where, I believe, the graphs speak for themselves.

credittrendsconsumertrendsmortgagetrends

Do any of these graphs look like things have turned the corner? Honestly, these numbers don’t even look like they are decelerating! Compare this with the (relatively few) graphs provided by JP Morgan.

jpmsubprimetrendshomeequitytrendjpmprimemortgagetrend

These aren’t directly comparable, as the categories don’t correspond to one another, and JP Morgan uses the more conservative 30-day delinquent instead of Citi’s 90+-day delinquent numbers. However, JP Morgan’s portfolio’s performance seems to be leveling out and even improving (with the possible exception of “Prime Mortgages”). Clearly, the pictures being painted of the future are very different for these institutions.

On the Stuff You Know About: I’ll be honest, this business about Citi benefiting from it’s own credit deterioration was confusing. Specifically, there is more going on when Citi refers to “credit value adjustments” than just profiting from it’s own Cittieness. However, Heidi Moore, of Deal Journal fame helped set me straight on this–the other things going on are dwarfed by the benefit I just mentioned. Here’s the relevant graphic from the earnings presentation:

cva-graphic

And, via Seeking Alpha’s Transcript, the comments from Ned Kelly that accompanied this slide:

Slide five is a chart similar to one that we showed last quarter which shows the movement in corporate credit spreads since the end of 2007. During the quarter our bond spreads widened and we recorded $180 million net gain on the value of our own debt for which we’ve elected the fair value option. On our non-monoline derivative positions counterparty CDS spreads actually narrowed slightly which created a small gain on a derivative asset positions.

Our own CDS spreads widened significantly which created substantial gain on our derivative liability positions. This resulted in a $2.7 billion net mark to market gain. We’ve shown on the slide the five-year bond spreads for illustrative purposes. CVA on our own fair value debt is calculated by weighting the spread movements of the various bond tenors corresponding to the average tenors of debt maturities in our debt portfolio. The debt portfolio for which we’ve elected the fair value options is more heavily weighted towards shorter tenures.

Notice that Citi’s debt showed a small gain, but it’s derivatives saw a large gain (the additional $166 million in gains related to derivatives was due to the credit of it’s counterparties improving). Why is this? Well, notice the huge jump in Citi’s CDS spread over this time period versus cash bonds, which were relatively unchanged. Now, from Citi’s 2008 10-K:

CVA Methodology

SFAS 157 requires that Citi’s own credit risk be considered in determining the market value of any Citi liability carried at fair value. These liabilities include derivative instruments as well as debt and other liabilities for which the fair-value option was elected. The credit valuation adjustment (CVA) is recognized on the balance sheet as a reduction in the associated liability to arrive at the fair value (carrying value) of the liability.

Citi has historically used its credit spreads observed in the credit default swap (CDS) market to estimate the market value of these liabilities. Beginning in September 2008, Citi’s CDS spread and credit spreads observed in the bond market (cash spreads) diverged from each other and from their historical relationship. For example, the three-year CDS spread narrowed from 315 basis points (bps) on September 30, 2008, to 202 bps on December 31, 2008, while the three-year cash spread widened from 430 bps to 490 bps over the same time period. Due to the persistence and significance of this divergence during the fourth quarter, management determined that such a pattern may not be temporary and that using cash spreads would be more relevant to the valuation of debt instruments (whether issued as liabilities or purchased as assets). Therefore, Citi changed its method of estimating the market value of liabilities for which the fair-value option was elected to incorporate Citi’s cash spreads. (CDS spreads continue to be used to calculate the CVA for derivative positions, as described on page 92.) This change in estimation methodology resulted in a $2.5 billion pretax gain recognized in earnings in the fourth quarter of 2008.

The CVA recognized on fair-value option debt instruments was $5,446 million and $888 million as of December 31, 2008 and 2007, respectively. The pretax gain recognized due to changes in the CVA balance was $4,558 million and $888 million for 2008 and 2007, respectively.

The table below summarizes the CVA for fair-value option debt instruments, determined under each methodology as of December 31, 2008 and 2007, and the pretax gain that would have been recognized in the year then ended had each methodology been used consistently during 2008 and 2007 (in millions of dollars).

cvatable

Got all that? So, Citi, in it’s infinite wisdom, decided to change methodologies and monetize, immediately, an additional 290 bps in widening on it’s own debt. This change saw an increase in earnings of $2.5 billion prior to this quarter.  In fact, Citi saw a total of $4.5 billion in earnings from this trick in 2008. However, this widening in debt spreads was a calendar year 2008 phenomenon, and CDS lagged, hence the out-sized gain this quarter in derivatives due to FAS 157 versus debt. Amazing.

And, while we’re here, I want to dispel a myth. This accounting trick has nothing to do with reality. The claim has always been that a firm could purchase it’s debt securities at a discount and profit from that under the accounting rules, so this was a form of mark-to-market. Well, unfortunately, rating agencies view that as a technical default–S&P even has a credit rating (“SD” for selective default) for this situation. This raises your cost of borrowing (what’s to say I’ll get paid in full on future debt?) and has large credit implications. I’m very, very sure that lots of legal documents refer to collateral posting, and other negative effects if Citi is deemed in “default” by a rating agency, and this would be a form of default. This is a trick, plain and simple–in reality, distressed tender offers would cost a firm money.

The Bottom Line: Citi isn’t out of the woods. In this recent earnings report I see a lot of reasons to both worry and remain pessimistic about Citi in the near- and medium-term. If you disagree, drop me a line… I’m curious to hear from Citi defenders.

How to Fix the Compensation Issue… Yesterday!

April 15, 2009

With all the tone-deafness that followed the great compensation debate of 2009, I have a very simple solution. The problem, despite what people commonly believe, is not the absolute level of compensation. No, it’s the fact that management’s personal incentives and employees’ incentives are aligned–shareholders are still in the wilderness. How many times have we heard the trite, absolutely silly refrain stating “we need to pay the valuable people that know where the bodies are buried so they can dispose of them!”? Way too many. Although, there are dozens of examples of retention bonuses being paid to people as they resign… Idiots.

So, what do I suggest? Add all compensation, beyond a base limit, say $250,000, as T.A.R.P. debt to institutions who have already received funds under the program–and the interest rate from this new debt should be very high. I would suggest… okay, I never merely suggest… I would demand (better!) that this new debt carry a high coupon. Maybe even ensure the interest owed is cutely linked to the way these publicly owned (partially, anyway) institutions are negatively impacting our economy. One example: this new debt could carry an interest rate equal to the greater of the (a) median of the top quartile of credit card interest rates issued by the company in question and (b) 24.99%.

Now, what does this do? It better aligns management and shareholders. How can a C.E.O. allow divisions that lost billions to run up it’s debt? And, how can an institution award these bonuses necessary to pay people, right out of taxpayer money, if they aren’t willing to pay it back later? By definition, every dollar that flows into the pockets of employees can’t go back to the taxpayers whose money saved these same institutions. Once managers need to actually justify why they are paying people, due to the higher cost, I guarantee fewer employees will receive these higher bonuses. Gone will be the cuspy performers who are being paid because Wall St. is a creature of habit. This will create a wholesale re-thinking of compensation at many institutions. And, honestly, it’s long overdue. To be honest, I don’t really view this higher cost as excessive, either. People being paid 8-12% of profits (it’s actually revenue traders are compensated on, but don’t tell anyone that) should wind up actually costing 10%-20% of profits with this excess debt, perhaps as high as 30%–but these employees continue to be employed and able to profit due to taxpayer funds to begin with. It’s time managers are required justify, to their boards and owners, why high compensation for various employees is necessary. And, since companies say a surtax or banning of bonuses is bad and bonuses are absolutely required, they should be more than willing to pay these higher rates–they need these people after all!

Exclusive Breaking News: Newspapers to Receive Massive Capital Infusion

March 31, 2009

Through some contacts in the banking industry I have obtained a draft of a news story that is expected to be run tomorrow. This is clearly newsworthy and I’m proud that something this important is the first news story ever to be broken by this blog. The full text of the story is below.

——

Newspaper Industry gets Large Capital Infusion

New York (AFD Wire) — Newspaper companies have “agreed in principle” on a deal to receive a $15 billion capital infusion over the next two years from a consortium of organizations focused on the pet industry. While the transaction details aren’t final yet, The Cat Fanciers Association, American Kennel Club, and the American Pet Products Association are expected to requested a one-time “emergency fee” from all members, totaling $5 billion, and will increased their dues and other membership fees to payout the remaining $10 billion quarterly over the next two years.

When called for a comment James Whittier, head of the American Kennel Club, who lead the negotiations on behalf of the pet industry, confirmed the talks and made the following statements regarding the transaction: “We have and have always had a strong bond with the newspaper industry. Before today we were emotionally and professionally invested in it’s survival–today, we will be announcing a financial investment as well. Without newspapers and their vital use in the housebreaking process there would be a massive oversupply of puppies and kittens without loving homes. Without newspapers it would be all-but-impossible for working individuals to own all but the strongest bladdered pets.”

John Exeter Ecstrum, or “Extra Extra” as he’s known to colleagues, lead the discussions on behalf of the newspaper industry. Mr. Ecstrum is a retired newspaper executive who has served as a director for The New York Times Co. (NYSE: NYT),  the Newspaper Association of America, and various private news and publishing companies. Mr Ecstrum, via his public relations team released a statement: “To show how strong the bond between the pet industry and the newspaper industry has become, our trade groups estimate that around 75% of physical newspapers are purchased for non-human use, up from just 30% ten years ago. This demonstrates the fastest growing segment of our business and we’re proud to strengthen and formalize that relationship with today’s announcement. This transaction showcases another example of websites, blogs, and online-only news failing to deliver the same service and usefulness as print news.”

Notably absent from the detailed list of participating organizations was the Westminster Kennel Club, the organization responsible for the the annual Westminster Kennel Club Dog Show. Ms. Margaret Ames Steubenpfoffer, IV, president of Westminster Corp., parent company of the Kennel Club, noted, “The club has very strict rules relating to the care of dogs that compete in our shows. Ever since 1995 we have required show dogs’ leavings be deposited on squares no smaller than three feet by three feet cut from bolts of low-grade silk.” Ms. Steubenpfoffer repeatedly re-iterated that using “newsprint” was inappropriate and degraded the quality of the living environment champion dogs required.

Parties close to the negotiations expect the details to be finalized this afternoon and a formal announcement of the specific terms, along with a draft agreement, to be released.

Why Stress Test Really Means Guesswork

March 15, 2009

Well, we’ve heard a ton about stress tests recently. Want some details on what a stress test entails? The Journal has some details about the tests here. Now, as much as I think GDP and unemployment are fine things to project forward for economists, let’s walk through the way one would use this to actually price an asset. Let’s start with something simple, like a 10-year treasury note (note that treasury bond specifically refers to bonds with a 30-year maturity). Here are all the components one would need to stress test the value of a treasury note.

  1. Characteristics of the note itself: coupon, payment dates, maturity dates, etc.
  2. What the yield curve would look like at the date you’re pricing the note.

Why would one need to know the shape of the yield curve (term structure of rates)? This is important, in order to “PV” the bond’s cashflows most accurately, one would discount each cashflow by it’s risk–the simplest proxy is to discount each cash flow by the rate of interest one would need to pay to issue a bond maturing on that date. For the government, this rate of interest is the point on the treasury yield curve (actually, the par zero curve) with the same maturity date. An example would be, if I were going to price a cash payment I will receive in two years, and the government can currently issue two-year debt at 5%, I should discount my cash payment (also from the government, since it’s a treasury note) at 5%. Treasuries are the simplest of all instruments to value.

Here’s an example, form the link above, of what a treasury yield curve might look like:

Normal Yield Curve

Now, it is completely and totally guesswork to figure out, given unemployment and GDP figures, what the yield curve will look like at any date in the future. Indeed, one can plug these projections into a model and it can come up with a statistical guess… But the only thing we know for sure about that guess is that it won’t be accurate, although it might be close. However, things like inflation will drive the longer end of the yield curve and monetary policy will drive the shorter end, so these certainly aren’t directly taken from the stress test parameters, but would need to be a guess based on those parameters. This is a large source of uncertainty in pricing even these instruments in the stress test.

Next, let’s examine a corporate bond. What would we need for a corporate bond?

  1. Characteristics of the bond: coupon, payment dates, maturity dates, special features (coupon steps, sinking funds, call schedules, etc.), where in the capital structure this bond sits, etc.
  2. What the yield curve would look like at the date you’re pricing the bond.
  3. The spreads that the corporation’s debt will carry at the date you’re pricing the bond.

Oh no. We already saw the issues with #2, but now we have #3. What will this corporations credit spread (interest/yield required in excess of the risk free rate) at the time of pricing? Will the corporations debt, which could trade at a spread of anywhere from 5 to 1500 basis points, be lower? higher? Will the corporations spread curve be flatter? steeper?

Here is a good illustration of what I’m referring to (from the same source as the figure above):

Credit Spread

There, the spread is the difference between the purple line and the black line. As you can see, it’s different for different maturity corporate bonds (which makes sense, because if a company defaults in year two, it’ll also default on it’s three year debt.. but the companies’ two year debt might never default, but the company might default during it’s third year, creating more risk for three year bonds issued by that company than two year bonds). It shouldn’t be a surprise, after our exercise above, to learn that the best way to compute the price of a corporate bond is to discount each cashflow by it’s risk (in my example above, regardless of whether the company defaults in year two or year three, the interest payments from both the three year and two year debt that are paid in one year have the same risk).

Well, how does one predict the structure of credit spreads in the future? Here’s a hint: models. Interest rates, however, are an input to this model, since the cost of a firm’s borrowing is an important input to figuring out a corporation’s cashflow and, by extension, creditworthiness. So now we have not only a flawed interest rate projection, but we have a projection of corporate risk that, in addition to being flawed itself, takes our other flawed projections as an input! Understanding model error yet? Oh, and yes unemployment and the health of the economy will be inputs to the model that spits out our guess for credit spreads in the future as well.

Next stop on the crazy train, mortgage products! What does one need to project prices for mortgage products?

  1. Characteristics of the bond: coupon, payment dates, maturity dates, structure of the underlying securitization (how does cash get assigned in the event of a default, prepayment, etc.), etc.
  2. What the yield curve would look like at the date you’re pricing the bond.
  3. The spreads that the debt will carry at the date you’re pricing the bond.
  4. What prepayments will have occurred by the date you’re pricing the bond and what prepayments will occur in the future, including when each will occur.
  5. What defaults will have occurred by the date you’re pricing the bond and what defaults will occur in the future, including when each will occur.

Oh crap. We’ve covered #1-3. But, look at #4 and #5 … To price a mortgage bond, one needs to be able to project out, over the life of the bond, prepayments and defaults. Each is driven bydifferent variables and each happens in different timeframes. Guess how each projection is arrived at? Models! What are the inputs to these models? Well, interest rates (ones ability to refinance depends on where rates are at the time) over a long period of time (keep in mind that you need rates over time, having rates at 5% in three years is completely different if rates where 1% or 15% for the three years before). General economic health, including regional (or more local) unemployment rates (if the south has a spike in unemployment, but the rest of the country sees a slight decrease, you’ll likely see defaults increase). And a myrid of other variables can be tossed in for good measure. So now we have two more models, driven by our flawed interest rate projections, flawed credit projections (ones ability to refinance is driven by their mortgage rate, which is some benchmark interest rate [treasuries here] plus some spread, from #3), and the unemployment and GDP projections.

I will, at this point, decline to talk about pricing C.D.O.’s … Just understand, however, that C.D.O.’s are portfolios of corporate and mortgage bonds, so they are a full extra order of magnitude more complex. Is it clear, now, why these stress tests, as they seem to be defined, aren’t all that specific, and potentially not all that useful?
