Since the economic collapse of 2008 there has been considerable
effort devoted to redrawing regulatory rules to protect the financial system
from future instability. The extent to which the new regulations implemented to
date enhance stability is debatable, but if the purpose was to prevent asset
bubbles of the sort that gave us the current downturn, arguably they have
already failed.
There is a fundamental issue here that is not sufficiently
appreciated. While the public’s attention was focused on the financial crises
that brought most major banks to the edge of insolvency, and pushed quite a few
over, the primary reason for the prolonged stagnation of the last five years
was the deflation of housing bubbles in much of the world.
The case for this is clearest in the United States. The
housing bubble was driving the economy in the years leading up to the collapse.
The unprecedented run-up in house prices led to a record pace of construction
in the years 2002-2006, even as the demographics would have predicted a
slowing. When the bubble burst, construction not only fell back to normal
levels, it dropped considerably below as a result of the enormous overbuilding
during the bubble years. This led to a loss in demand in residential
construction of more than 4 percentage points of GDP, or $640 billion in annual demand
in the current economy.
The bubble also led to an extraordinary consumption boom,
due to wealth effect from $8 trillion in bubble generated housing equity. The
saving rate fell to nearly zero in the years 2004-2007. When the bubble burst
and this equity vanished, the U.S. economy lost close to $400 billion in
consumption demand, 2.5 percent of GDP in today’s economy.
This is the story of the downturn in the United States;
there is no magic potion that will replace this lost demand, especially when
the Fed is constrained by the zero bound. It is difficult to see how anything
would be very different today if there had been no financial crisis. For all
the talk of troubled banks, few small businesses cite lack of credit as major
problem. Furthermore, credit is available at record low cost to larger firms,
who clearly do not see many investment opportunities.
If the proximate cause of the economy’s troubles are burst asset
bubbles, and not over-leveraged financial institutions, then it would make
sense to focus more of our attention on the former than the latter.
Unfortunately, the picture here is not very encouraging.

The bubble in the United States has deflated with house
prices now more or less in line with their trend levels. However this is not
the case everywhere. In several countries house prices have at best partially
deflated from bubble peaks.
This is most clearly the case in Canada and Australia where inflation-adjusted
prices are at or above their pre-crisis levels. The story is not much different in
the United Kingdom. Prices are down by 25 percent from their bubble peak, but still
more than twice their mid-1990s level. Homeowners in France might also have
some grounds for concern given that prices there also are at pre-bubble peaks
and close to double the mid-1990s levels.
Of course a run-up in prices doesn’t necessarily mean a
bubble; it could reflect an increased demand for housing relative to other
items. This doesn’t seem to fit with the fact that all of these countries have
seen a sharp rise in the sale price to rent ratio over the last two decades. In
this respect it is also worth noting that median house prices in all of these
countries are now 50-100 percent higher than in the United States. Given their
lower per capita incomes, this would imply a willingness to spend a much larger
share of income on housing than in the United States.
Some analysts argue that current house prices are justified
by the extraordinary low interest rates of recent years. In this view, if the
implicit rental value of owning a home is viewed as comparable to interest on a
bond, then we would expect a strong inverse relationship between house prices
and interest rates.
There are two points to be made on this argument. First, we
have not generally seen this pattern in the past. House prices have not been
hugely responsive to interest rates in most countries over the last four
decades. This means that if house prices will now fluctuate like bond prices in
response to interest rates, it marks a change in the behavior of this market.
The other more important point is that if house prices now
fluctuate like bond prices, then this view also implies that house prices will
tumble if interest rates return to more normal levels as the economy recovers.
If we think of house prices moving like long-term bonds then a doubling of
interest rates will cause house prices to fall by roughly 50 percent. This view
implies the same sort of future plunge in house prices as the bubble story,
albeit for a different reason.
This sort of plunge in house prices would be no big deal if
homeowners thought of their houses like bonds, with the corresponding response
to fluctuations in interest rates. However, this is probably not the case. For
example, if overnight rates go from near zero to 2.2 percent in three years,
and 10-year Treasury rates rise from a recent low of 1.6 percent to 4.5
percent, as projected by the Congressional Budget Office in the United States,
then will people in Canada, the U.K., and Australia expect their house prices
to fall by 50 percent?
Assuming that most homeowners do not anticipate
this sort of plunge in prices, and have not hedged themselves against this
possibility, we may be in for another round of very bad news if interest rates
ever return to more normal levels. It is remarkable that the latest run-up in
house prices has received so little attention from people in policy positions.
There may be an enormous price to pay for the continued lack of attention to
housing bubbles.
