Michael J. Burry: How did nobody see this coming??

ALAN GREENSPAN, the former chairman of the Federal Reserve, proclaimed last month that no one could have predicted the housing bubble. “Everybody missed it,” he said, “academia, the Federal Reserve, all regulators.”

But that is not how I remember it. Back in 2005 and 2006, I argued as forcefully as I could, in letters to clients of my investment firm, Scion Capital, that the mortgage market would melt down in the second half of 2007, causing substantial damage to the economy. My prediction was based on my research into the residential mortgage market and mortgage-backed securities. After studying the regulatory filings related to those securities, I waited for the lenders to offer the most risky mortgages conceivable to the least qualified buyers. I knew that would mark the beginning of the end of the housing bubble; it would mean that prices had risen — with the expansion of easy mortgage lending — as high as they could go.

I had begun to worry about the housing market back in 2003, when lenders first resurrected interest-only mortgages, loosening their credit standards to generate a greater volume of loans. Throughout 2004, I had watched as these mortgages were offered to more and more subprime borrowers — those with the weakest credit. The lenders generally then sold these risky loans to Wall Street to be packaged into mortgage-backed securities, thus passing along most of the risk. Increasingly, lenders concerned themselves more with the quantity of mortgages they sold than with their quality.

Meanwhile, home buyers, convinced by recent history that real estate prices would always rise, readily signed onto whatever mortgage would get them the biggest house. The incentive for fraud was great: the F.B.I. reported that its mortgage fraud caseload increased fivefold from 2001 to 2004.

At the same time, I also watched how ratings agencies vouched for subprime mortgage-backed securities. To me, these agencies seemed not to be paying much attention.

By mid-2005, I had so much confidence in my analysis that I staked my reputation on it. That is, I purchased credit default swaps — a type of insurance — on billions of dollars worth of both subprime mortgage-backed securities and the bonds of many of the financial companies that would be devastated when the real estate bubble burst. As the value of the bonds fell, the value of the credit default swaps would rise. Our swaps covered many of the firms that failed or nearly failed, including the insurer American International Group and the mortgage lenders Fannie Mae and Freddie Mac.

A Life Assurer's Worst Nightmare - Incorrect Assumptions

Like the sub-prime crisis faced by banks, the risk of people living for up to 20 years after retirement seems to have crept up on an industry using historical data to calculate people's chances of an early death.

Pension funds and insurers say the mounting burden of protracted pension payments is concentrated on a small group of providers: them.

Global private sector liabilities for pensions are at about $25 trillion (R180 trillion), according to a January Pensions Institute report, which cited estimates that every extra year of life expectancy at age 65 adds about 3 percent to the value of some UK pension liabilities.

Several factors - the market crash brought on by subprime lending, new solvency rules for insurers due in 2012 and the stampede of baby-boomers to retirement age - are adding urgency to providers' efforts to spread their exposure.

If that seems like a small group, the evidence is it's the population segment most likely to grow. There are about 450 000 centenarians in the world today and experts estimate that there could be 1 million by 2030.

Why China Insists on Controlling its Currency

U.S.-Chinese relations have become tenser in recent months, with the United States threatening to impose tariffs unless China agrees to revalue its currency and, ideally, allow it to become convertible like the yen or euro. China now follows Japan and Germany as one of the three major economies after the United States. Unlike the other two, it controls its currency’s value, allowing it to decrease the price of its exports and giving it an advantage not only over other exporters to the United States but also over domestic American manufacturers. The same is true in other regions that receive Chinese exports, such as Europe.

What Washington considered tolerable in a small developing economy is intolerable in one of the top five economies. The demand that Beijing raise the value of the yuan, however, poses dramatic challenges for the Chinese, as the ability to control their currency helps drive their exports. The issue is why China insists on controlling its currency, something embedded in the nature of the Chinese economy. A collision with the United States now seems inevitable. It is therefore important to understand the forces driving China, and it is time for STRATFOR to review its analysis of China.

An Inherently Unstable Economic System

China has had an extraordinary run since 1980. But like Japan and Southeast Asia before it, dramatic growth rates cannot maintain themselves in perpetuity. Japan and non-Chinese East Asia didn’t collapse and disappear, but the crises of the 1990s did change the way the region worked. The driving force behind both the 1990 Japanese Crisis and the 1997 East Asian Crisis was that the countries involved did not maintain free capital markets. Those states managed capital to keep costs artificially low, giving them tremendous advantages over countries where capital was rationally priced. Of course, one cannot maintain irrational capital prices in perpetuity (as the United States is learning after its financial crisis); doing so eventually catches up. And this is what is happening in China now.

STRATFOR thus sees the Chinese economic system as inherently unstable. The primary reason why China’s growth has been so impressive is that throughout the period of economic liberalization that has led to rising incomes, the Chinese government has maintained near-total savings capture of its households and businesses. It funnels these massive deposits via state-run banks to state-linked firms at below-market rates. It’s amazing the growth rate a country can achieve and the number of citizens it can employ with a vast supply of 0 percent, relatively consequence-free loans provided from the savings of nearly a billion workers.

It’s also amazing how unprofitable such a country can be. The Chinese system, like the Japanese system before it, works on bulk, churn, maximum employment and market share. The U.S. system of attempting to maximize return on investment through efficiency and profit stands in contrast. The American result is sufficient economic stability to be able to suffer through recessions and emerge stronger. The Chinese result is social stability that wobbles precipitously when exposed to economic hardship. The Chinese people rebel when work is not available and conditions reach extremes. It must be remembered that of China’s 1.3 billion people, more than 600 million urban citizens live on an average of about $7 a day, while 700 million rural people live on an average of $2 a day, and that is according to Beijing’s own well-scrubbed statistics.

Moreover, the Chinese system breeds a flock of other unintended side effects.

Effects of Uncertainty on Investing

Humans don't like ambiguity. This is demonstrated in the experiment Hersh Shefrin discusses where subjects are offered either a guaranteed $1000, or a 50/50 chance at $2000. Consistently, fewer than 50% of respondents prefer the gamble for $2000, even though the expected values (i.e. the average value of the result if it were conducted many times) of both offers are the same.

What if the 50/50 odds in the above experiment were instead unknown? This adds even further uncertainty to the situation, and results in even fewer people willing to gamble on the $2000.

Shefrin calls this phenomenon "aversion to ambiguity", and on Wall Street it results in downward pressure on the prices of securities with uncertain outlooks. In order to avoid uncertainty/ambiguity, humans will stay away, even if the odds are favourable (i.e. downside risk is low, upside potential is high).

In his book, Shefrin argues that this ambiguity aversion is the reason for government intervention, even when it is not needed. What would have happened had the government not bailed out the banks? Nobody really knows, but the fact that the outlook was uncertain made the government want to intervene, even at a high cost, in order to avoid the uncertain situation.

As Mohnish Pabrai notes in his book, risk is not the same as uncertainty. Uncertainty can drive down the prices of assets/securities, even if downside risk is low. By capitalizing on situations where uncertainty is high, but risk is low, the investor can put himself in a position to earn above-average returns.
