Historical vol

Worried now? Graph from maoxian. Check these out.

Too bad I don’t have my vol trade on any more… I bought some vol back in 2004 or so (long-dated VIX options), which looks to have been near the bottom 🙂

Meltdown links

with 3 comments

1) Leonard Lopate interview with Economist editor Greg Ip, formerly of the WSJ. (Scroll down the page to Financial Crisis: What Happens Next?). This is the best 12 minute summary of the current situation I have yet heard. Ip is consistently good at explaining this complicated subject in an accessible manner. If you have a friend who is confused about the credit crisis, have them listen to this interview. (Avoid Terri Gross and pals on this one… 😉

I have been listening to Leonard Lopate’s show for some time and I can tell his grasp of finance has increased dramatically in the last year or so (his strength is interviewing artists, writers, etc.). It’s yet another example of high-g at work. He knew almost nothing a year ago but now asks occasional perceptive questions. (But of course it doesn’t matter how smart our next President is!)

2) Mark Thoma discusses the pros and cons of mark to market accounting. To me it’s rather obvious that M2M accounting is exacerbating this crisis. It has introduced a very significant nonlinearity, both on the upside (bubble), and now in the collapse. If the market for mortgage assets has failed it is crazy to use it as a barometer for value. More discussion at WSJ.

3) This NYTimes Op-Ed written by a former theoretical physicist discusses agent-based simulation, behavioral economics and phase transitions — yes, in an Op-Ed! (Thanks again to reader STS for the pointer.)

Human capital

The Role of Education Quality for Economic Growth
Eric A. Hanushek and Ludger Woessmann (

The figure shows, by country, the share of students that scored very low (< 400 rough PISA equivalent, “scientifically and mathematically illiterate”) or very high (> 600) on cognitive tests administered over the last 40 years. The results give a good indication of the quality of human capital in the country’s workforce. Click for larger version.

From the paper:

…To create our measure of quality of education employed in this study, we use a simple average of the transformed mathematics and science scores over all the available international tests in which a country participated, combining data from up to nine international testing occasions and thirty individual test point observations. This procedure of averaging performance over a forty year period is meant to proxy the educational performance of the whole labor force, because the basic objective is not to measure the quality of students but to obtain an index of the quality of the workers in a country.

If the quality of schools and skills of graduates are constant over time, this averaging is appropriate and uses the available information to obtain the most reliable estimate of quality. If on the other hand there is changing performance, this averaging will introduce measurement error of varying degrees. [i.e., younger workers in developing countries probably have better skills than indicated in the data.]

More PISA fun.

Why no bailout?

with 2 comments

Representatives in Congress received thousands of phone calls and emails from constituents against the bailout, which some wags have characterized as “no banker left behind” 🙂

We can trace this popular reaction against CEOs and Wall St. to growing income and wealth inequality. Ordinary people no longer feel they have a stake in the system. Their reaction may be irrational (even the poorest American has a big stake in the continued functioning of the economy), but it was certainly predictable.

Next spring, unlike last year, less than half of the Harvard graduating class will take jobs in finance. I guess that signals a top in the market 8-/

Complexity illustrated: Lehman WAS too connected to fail

with 4 comments

This WSJ article illustrates what I discussed more abstractly in this earlier post Notional vs net: complexity is our enemy. The story claims that by allowing Lehman to fail, Treasury and the Fed triggered the final stage of the crisis that got us to where we are today. I’ve included my figures from the earlier post here.

…in an age where markets, banks and investors are linked through a web of complex and opaque financial relationships, the pain of letting a large institution go has proved almost overwhelming.

In hindsight, some critics say the systemic crisis that has emerged since the Lehman collapse could have been avoided if the government had stepped in.

The Fed had been pushing Wall Street firms for months to set up a new clearinghouse for credit-default swaps. The idea was to provide a more orderly settlement of trades in this opaque, diffuse market with a staggering $55 trillion in notional value, and, among other things, make the market less vulnerable if a major dealer failed. But that hadn’t gotten off the ground. As a result, nobody knew exactly which firms had made trades with Lehman and for what amounts. On Monday, those trades would be stuck in limbo. In a last-ditch effort to ease the problem, New York Fed staff worked with Lehman officials and the firm’s major trading partners to figure out which firms were on opposite sides of trades with Lehman and cancel them out. If, for example, two of Lehman’s trading partners had made opposite bets on the debt of General Motors Corp., they could cancel their trades with Lehman and face each other directly instead.

This figure shows three trades which almost cancel. Remove one of the counterparties and you have chaos instead of hedges. In a last ditch effort, after letting Lehman fail, Treasury tried to cancel these trades out manually — good luck! Why did we not have a central exchange in place earlier?

Oops, there goes AIG! (Big issuer of CDS insurance.)

The reaction was most evident in the massive credit-default-swap market, where the cost of insurance against bond defaults shot up Monday in its largest one-day rise ever. In the U.S., the average cost of five-year insurance on $10 million in debt rose to $194,000 from $152,000 Friday, according to the Markit CDX index.

When the cost of default insurance rises, that generates losses for sellers of insurance, such as banks, hedge funds and insurance companies. At the same time, those sellers must put up extra cash as collateral to guarantee they will be able to make good on their obligations. On Monday alone, sellers of insurance had to find some $140 billion to make such margin calls, estimates asset-management firm Bridgewater Associates. As investors scrambled to get the cash, they were forced to sell whatever they could — a liquidation that hit financial markets around the world. …AIG was one of the biggest sellers in the default insurance market, with contracts outstanding on more than $400 billion in bonds.

To make matters worse, actual trading in the CDS market declined to a trickle as players tried to assess how much of their money was tied up in Lehman. The bankruptcy meant that many hedge funds and banks that were on the profitable side of a trade with Lehman were now out of luck because they couldn’t collect their money.

…At around 7 a.m. Tuesday in New York, the market got its first jolt of how bad the day was going to be: In London, the British Bankers’ Association reported a huge rise in the London interbank offered rate, a benchmark that is supposed to reflect banks’ borrowing costs. In its sharpest spike ever, overnight dollar Libor had risen to 6.44% from 3.11%. But even at those rates, banks were balking at lending to one another.

Who was next after AIG? Time for a bailout!

…Goldman, Paulson’s former employer, had up to $20B of CDS exposure to AIG. The current head of Goldman was the only Wall St. executive invited to the meetings between AIG and the government. Conflict of interest for soon to be King Henry Paulson?

Clawbacks, fake alpha and tail risk

with 2 comments

Earlier this year I wrote a post Fake alpha, compensation and tail risk in finance:

…current banking and money management compensation schemes create incentives for taking on tail risk… and disguising it as alpha. The proposed solution: holdbacks or clawbacks of bonus money… When will shareholders smarten up and enforce this kind of compensation scheme on management at public firms?

The classic example is writing naked (unhedged) insurance policies covering rare events and pocketing the fees as alpha. You trade tail risk for cash, and hope things don’t blow up until you are out the door. It’s agency risk on steroids.

This NYTimes article describes, in detail, a perfect example of this phenomenon in the case of AIG. AIG, a global insurance company with over 100k employees, was brought down by a tiny unit in London that traded credit default swaps (CDS).

Once it became clear that AIG was in trouble, Treasury and the Fed had to step in because AIG was too connected to fail. In fact, the article states that Goldman, Paulson’s former employer, had up to $20B of CDS exposure to AIG. The current head of Goldman was the only Wall St. executive invited to the meetings between AIG and the government. Conflict of interest for soon to be King Henry Paulson?

Joseph Cassano, the former head of AIG’s London credit derivatives unit, is perhaps the first (although probably not the last) poster boy for clawbacks in the credit crisis. Total compensation for his unit of 377 employees averaged over $1 million per employee in recent years. I would guess that means Cassano took home easily in the tens and perhaps over 100 million dollars in the last few years. Will taxpayers get back any of that compensation?

“It is hard for us, without being flippant, to even see a scenario within any kind of realm of reason that would see us losing one dollar in any of those transactions.”

— Joseph J. Cassano, a former A.I.G. executive, August 2007

NYTimes …Although America’s housing collapse is often cited as having caused the crisis, the system was vulnerable because of intricate financial contracts known as credit derivatives, which insure debt holders against default. They are fashioned privately and beyond the ken of regulators — sometimes even beyond the understanding of executives peddling them.

Originally intended to diminish risk and spread prosperity, these inventions instead magnified the impact of bad mortgages like the ones that felled Bear Stearns and Lehman and now threaten the entire economy.

In the case of A.I.G., the virus exploded from a freewheeling little 377-person unit in London, and flourished in a climate of opulent pay, lax oversight and blind faith in financial risk models. It nearly decimated one of the world’s most admired companies, a seemingly sturdy insurer with a trillion-dollar balance sheet, 116,000 employees and operations in 130 countries.

“It is beyond shocking that this small operation could blow up the holding company,” said Robert Arvanitis, chief executive of Risk Finance Advisors in Westport, Conn. “They found a quick way to make a fast buck on derivatives based on A.I.G.’s solid credit rating and strong balance sheet. But it all got out of control.”

…The insurance giant’s London unit was known as A.I.G. Financial Products, or A.I.G.F.P. It was run with almost complete autonomy, and with an iron hand, by Joseph J. Cassano, according to current and former A.I.G. employees.

…These insurance products were known as “credit default swaps,” or C.D.S.’s in Wall Street argot, and the London unit used them to turn itself into a cash register.

The unit’s revenue rose to $3.26 billion in 2005 from $737 million in 1999. Operating income at the unit also grew, rising to 17.5 percent of A.I.G.’s overall operating income in 2005, compared with 4.2 percent in 1999.

Profit margins on the business were enormous. In 2002, operating income was 44 percent of revenue; in 2005, it reached 83 percent.

Mr. Cassano and his colleagues minted tidy fortunes during these high-cotton years. Since 2001, compensation at the small unit ranged from $423 million to $616 million each year, according to corporate filings. That meant that on average each person in the unit made more than $1 million a year.

Update: from the Pelosi bailout legislation summary — good luck implementing this!

New restrictions on CEO and executive compensation for participating companies:

* No multi-million dollar golden parachutes
* Limits CEO compensation that encourages unnecessary risk-taking
* Recovers bonuses paid based on promised gains that later turn out to be false or inaccurate
