Today I am going to ask three simple questions that have easy to understand answers.
- What Causes Economic Bubbles?
- When Do Bubbles Burst?
- Can the Fed Prevent Bubbles?
The Boy Who Cried Bubble
Before answering the questions (and hopefully many of you know the answers already), let's tune in to what the Dallas Fed has to say regarding bubbles in its report
Globalization and Monetary Policy Institute Working Paper No. 167, entitled "
The Boy Who Cried Bubble" by authors Yasushi Asako and Kozo Ued.
The article is 44 pages long. In the opening paragraph on page two, the authors state "History is rife with examples of bubbles and bursts. A prime example is the recent financial crisis that started in the summer of 2007; However, we have limited knowledge of how bubbles arise and how they can be prevented."
One could safely stop reading right at that point knowing full well that what follows cannot possibly be anything but self-serving platitudes and incomprehensible mathematical gibberish.
And that is precisely the case. The mathematical gibberish starts on page five and continues for the entire remainder of the document.
Here is a quick sample from page seven.
All the remaining pages are equally incomprehensible to all but the geekiest of geeks. Here is another example from page 39.
Hiding Behind Nonsensical Math
I am quite sure there are some academic geeks who understand the formulas presented by Yasushi Asako and Kozo Ued.
Regardless, it's all mathematical nonsense in light of their ridiculous conclusion stated upfront "
We have limited knowledge of how bubbles arise and how they can be prevented."
It's So Tasty Too!
What Causes Economic Bubbles?
Every economic bubble in history started with reckless expansion of money supply and credit, reckless manipulation of interest rates, or government promotions of "low-risk" something for nothing schemes.
That statement holds true for everything from the Tulip Bubble, to the John Law Mississippi Bubble, to the 1929 Stock Market Crash, to the Housing Bubble.
For example,
Tulipmania was a futures manipulation and options scheme (credit with leverage) accompanied by futures rules changes enacted by the Dutch Legislature in 1636.

Dissecting the Fed-Sponsored Housing Bubble
Every time in history, even as late as 2007, those who caused the bubbles could not see them.
Housing in particular should have been easy to spot. Anyone who could breathe could get a mortgage. Housing prices spiraled three standard deviations from rent.
Yet, Bernanke did not see the housing bubble.
How?
The Fed did not consider asset inflation, including home prices. Instead of focusing on the Home Price Index (HPI) or numerous other housing indices (all showing bubble conditions), the Fed focused on Owners' Equivalent Rent (OER).
Here is the pertinent discussion from
Dissecting the Fed-Sponsored Housing Bubble
Comparative Growth in HPI vs. OER
From 1994 until 1999 there was little difference in the rate of change
of rent vs. housing prices. That changed in 2000 with the dot.com crash
and accelerated when Greenspan started cutting rates.
The bubble is clearly visible but neither the Greenspan nor the Bernanke
Fed spotted it. The Fed was more concerned with rents as a measure of
inflation rather than speculative housing prices.
Fed Funds Rate vs. CPI and HPI-CPI
The above chart shows the effect when housing prices replace OER in the
CPI. In mid-2004, the CPI was 3.27%, the HPI-CPI was 5.93% and the Fed
Funds Rate was a mere 1%. By my preferred measure of price inflation,
real interest rates were -4.93%. Speculation in the housing bubble was
rampant.
In mid-2008 when everyone was concerned about "inflation" because oil
prices had soared over $140, I suggested record low interest rates
across the entire yield curve. At that time the CPI was close to 6% but
the HPI-CPI was close to 0% (and plunging fast).
As measured by HPI-CPI real interest rates were positive from mid-2006
all the way to 2010, even when the Fed Funds rate crashed to .25%. That
shows the power of the housing crash.
Real rates went positive again in mid-2010 until early 2011.
CPI and HPI-CPI Variance From Fed Funds Rate
The above chart shows the "Real" (inflation adjusted) Fed Funds Rate as
measured by the Fed funds rate minus the CPI, and a second time by the
Fed Funds Rate minus the HPI-CPI.
With the recent rise in housing prices, the HPI-CPI is
2.78% while the CPI as stated by the BLS is 1.76% (both numbers from November).
In my estimation, the BLS and Fed now understate price inflation by a
full percentage point. Inflation as measured by expansion of credit is
another matter.
Variance Between the CPI and HPI-CPI
The above chart shows the difference between the CPI and HPI-CPI. Note
that the largest negative discrepancy marked the exact top of the
housing market in summer of 2005.
Too Low Too Long
In short, the Fed held interest rates too low, too long, fueling asset inflation and credit expansion on ever-easing terms, the primary way in which bubbles are blown.
Government policy, notably President Bush's "Ownership Society" coupled with countless "affordable housing programs" and Greenspan's promotion of variable interest rate loans and derivatives was icing on the bubbleicious cake.
When Do Bubbles Burst?
In contrast to what Yasushi Asako and Kozo Ued suggest, I propose we know a heck of a lot about how bubbles burst. Here is the simple answer:
Bubbles burst when the pool of greater fools runs out.
Yes, it is precisely that simple.
Bear in mind, timing can be difficult, but sometimes there are precise clues. The housing bubble burst within a month of people standing in long lines and entering lotteries for the right to buy Florida condos.
Sentiment
Lesson: Sentiment can always get more extreme (Until it can't). I used sentiment to call the precise top of the housing bubble in summer of 2005. Here is a brief
flashback history. I updated that chart numerous times, in real time, since then.
I also called the 2007 stock market top in 2007 within a few percent based on sentiment. See
Quotes of the Day / Top Call
That said, it's easy enough to think sentiment can't get more extreme when it can. The third time was not a charm when I called a market top on February 3, 2003 in
Extreme Sentiment: Barron's Cover "Get Ready for Record Dow - We Told You So"; Top Call
Law of Predictions
Make enough predictions and sooner or later you are going to look mighty foolish. Since someone is bound to point them out, you may as well admit them yourself.
That said, my underlying thesis is correct: Once gain the Fed has totally and completely ignored asset price inflation, and once again, the Fed cannot see a massive bubble staring them right in the face.
This bubble will bust, on time, like all other bubbles, as soon as the pool of greater fools runs out.
Can Bubbles Be Prevented?
That is kind of a trick question. The correct answer is "In general, bubbles can be prevented".
The "trick" is I modified the question from the title of this article "
Can the Fed Prevent Bubbles?"
The answer to the question as originally posed is an emphatic "No!"
The Fed cannot prevent what it cannot see, even after the fact, when bubbles are in plain sight to any clear-thinking person.
More importantly, the biggest cause of economic bubbles is the Fed (central banks in general).
It is axiomatic that the cure for the disease cannot possibly be the same as the cause of the disease (the Fed).
Academic Wonderland vs. the Real World
A small bit of common sense is far better than ridiculous formulas that cannot possibly work in the real world.
The way to prevent bubbles is easy enough in theory:
Get rid of the Fed; get rid of government-sponsored corporatism; stop government central-planning activities, and instead try free-market economic solutions.
Since no Fed-sponsored research could possibly come to the correct conclusion, the Fed and its research departments both sit in academic wonderland, hiding behind obscure mathematical absurdities that do not and cannot work in the real world.
