ECONOMY: Economies Evolve, Too
By Niall Ferguson
The subprime mortgage crisis may wipe out a certain species of
financial institution altogether. Shed no tears. By Niall Ferguson.
“Just as some species become extinct in nature, some new financing techniques
may prove to be less successful than others.”
The remark was made to Congress in September by Anthony Ryan,
assistant secretary of the Treasury. Only when we know the true magnitude
of the current financial crisis will we be able fully to appreciate the significance
of his words.
Analogies between finance and evolution are nothing new. “The survival
of the fittest” is a phrase that aggressive traders like to use. “It’s Darwinian out
there” is a stock utterance by hedge fund managers after an especially tough
week. Back in November 2005, a conference hosted by the investment bank
Goldman Sachs was titled “The Evolution of Excellence.”
Yet, as became clear at that gathering, when financial practitioners use such
terms they seldom understand just how pertinent they are. A long-run historical
analysis of the development of financial services, going all the way back
to the days of Charles Darwin, strongly suggests that evolutionary forces are
as much at work in the realm of money as they are in the natural world.
The big question for our time is: are we on the brink of a “great dying”—
one of those mass extinctions of species that have occurred periodically in
the history of life on earth, such as the Cretaceous-Tertiary crisis that killed
off the dinosaurs? It is a scenario that many biologists fear, as human-caused
climate change wreaks havoc with natural habitats around the globe. Financial analysts have their own great dying to worry about as another humanmade
disaster, the subprime mortgage crisis, works its way through the
global financial system.
THE ORIGIN OF FINANCIAL SPECIES
The notion that Darwinian processes may be at work in the economy was
raised by Thorstein Veblen, the Norwegian-American economist best
known for his Theory of the Leisure Class, as long ago as 1899. An academic
journal has been devoted to the subject for the past 16 years, though most
economists remain skeptical about the applicability of Darwin’s ideas to the
economic sphere. The analogy is in fact surprisingly good in the case of the
financial-services industry, which has many of the defining characteristics
of a true evolutionary system:
- Genes, in the sense that certain business practices perform the same
role as genes in biology, allowing information to be stored in the
organizational memory and passed on from individual to individual
or from company to company when a new one is created.
- The potential for spontaneous mutation, usually referred to in
the economic world as innovation, and primarily, though by no
means always, technological
- Competition among individuals within a species for resources,
with the outcomes in terms of longevity and proliferation determining
which business practices persist.
- A mechanism for natural selection through the market allocation
of capital and human resources and the possibility of death in cases
of underperformance—in other words, differential survival.
- Scope for speciation, sustaining biodiversity through the creation
of wholly new species of financial institutions.
- Scope for extinction, with species dying out altogether.
Financial history is essentially the result of institutional mutation and
natural selection. Random drift (innovations/mutations that are not promoted
by natural selection, but just happen) and flow (innovations/mutations
that are caused when, say, U.S. practices are adopted by Chinese
banks) play a part. There can also be coevolution, when different financial
species work and adapt together (like hedge funds and their prime brokers).
But market selection is the main driver. Financial organisms are in competition
with one another for finite resources. At certain times and in certain
places, certain species may become dominant. But innovations by
competitor species, or the emergence of
altogether new species,
prevent any permanent
hierarchy or monoculture
from emerging. Broadly speaking, the law of the survival of the fittest applies.
Institutions with a “selfish gene” that is good at self-replication (and selfperpetuation)
will tend to endure and proliferate.
Economies Evolve, Too

The analogy is, of course, not perfect. When one organism ingests
another in the natural world, it is just eating, whereas in financial services,
mergers and acquisitions can lead directly to mutation. Among financial
organisms, there is no counterpart to the role of sexual reproduction. Most
financial mutation is deliberate, conscious innovation rather than random
change. Indeed, because a company can adapt within its own lifetime to
change going on around it, financial evolution (like cultural evolution)
may be best described not as Darwinian but as Lamarckian,
after the French biologist who contended that an
individual organism could acquire new and heritable traits. Still, the resemblances outnumber the differences—and
evolution offers a better model for understanding financial change than any
other we have.
Genes,mutation, competition, biodiversity, extinction—it’s no wonder
businesspeople see their world as “Darwinian.”
Rudolf Hilferding, a German socialist, predicted a century ago an inexorable
movement toward concentration of ownership in “financial capitalism.”
The conventional view of financial development does indeed see the
process from the vantage point of the big survivor. In the successful company’s
official family tree, numerous small companies are seen to converge
over time on a common trunk, the present-day conglomerate—the kind of
giant “überbank” that Hilferding imagined would ultimately take over the
entire financial system. This, however, is precisely the wrong way to think
about financial evolution. Over the long run, financial innovation begins
at a common trunk. Over time, the trunk branches outward as new kinds
of banks and other financial institutions evolve. The fact that a particular
institution successfully devours smaller rivals along the way is more or less
irrelevant. In the evolutionary process, animals eat one another, but that is
not the driving force behind evolutionary mutation and the emergence of
new species and subspecies.
Economies of scale and scope are not always the driving force in financial
history. More often, the real drivers are the process of speciation—when
new types of companies are created—and the equally recurrent process of
“creative destruction,” whereby weaker companies die out or, more commonly,
get eaten.
Take the case of retail and commercial banking, where considerable “biodiversity”
remains. North American and some European markets still have
highly fragmented retail banking sectors. The cooperative banking sector
has seen the most change, with high levels of consolidation (especially following
the crisis of the 1980s surrounding the U.S. savings and loans industry)
and most institutions moving to shareholder ownership. But the only
species that is now close to extinction in developed countries is the stateowned
bank, as privatization has swept the world.
In other respects, the story is one of speciation—the proliferation of new
types of financial institutions—which is just what we would expect in a
truly evolutionary system. Many new “monoline” financial services companies
have emerged in commercial banking, especially in consumer
finance (for example, Capital One). A number of new boutiques now exist
to cater to the private banking market. Direct banking (by telephone and
the Internet) is another relatively recent and growing phenomenon
throughout the developed world.
Likewise, even as giants have formed in the realm of investment banking,
new and nimbler species have evolved and proliferated. Although what
many recognize as the first hedge fund was established as long ago as 1949,
their emergence as big players in global financial markets is a relatively
recent phenomenon. In 1992, there were just 400 hedge funds, with $50
billion in assets under management. By the end of 2006, the number had
increased more than twentyfold and assets under management by a factor
of nearly thirty. And by the second quarter of 2007, there were 9,767 such
funds, with $1,740 billion under management.
Thanks to leverage, the estimated gross investments of the five largest
funds amount to around $100 billion. Altogether, hedge funds now
account for between one-third and one-half of all trading in the U.S. and
British equity and bond markets.
Innovations by competitor species, or the emergence of altogether new
species, forestall any permanent hierarchy or monoculture.
Meanwhile, there has been a somewhat smaller surge in the number of
private equity partnerships and the assets they manage, and the rapidly
accruing hard currency reserves of exporters of manufactured goods and
energy are producing a second generation of sovereign wealth funds.
Not only are new forms of financial institution proliferating; so too are
new forms of financial assets and services. In recent years, investors’
appetites have grown dramatically for mortgage-backed and other assetbacked
securities. The use of derivatives has also increased significantly.
In evolutionary terms, then, the financial services sector appears to be
in the midst of a kind of “Cambrian explosion,” with existing species flourishing and new species (such as hedge funds and private equity partnerships)
increasing in number. Yes, there are giants such as Citigroup. But, as
in the natural world, their existence does not preclude the evolution and
continued existence of smaller species. Size is not everything, in finance as
in nature.
Even as giants have formed, new and nimbler species of investment
banks have evolved and proliferated.
Indeed, the very difficulties that arise as publicly owned companies
become larger and more complex—the diseconomies of scale associated
with bureaucracy, the pressures associated with quarterly reporting—make
it probable that new kinds of private firms will proliferate. What matters
in evolution is not your size or your complexity. All that matters is that you
are good at surviving and passing on your genes. The financial equivalent
of evolutionary success is being good at generating returns on equity and
generating imitators employing a similar business model. Both are easier
for small firms.
SHOCKS LEADING TO EXTINCTION
Mutation and speciation have usually been evolved responses to the environment
and competition, with natural selection determining which new traits
become widely disseminated. The evolutionary process, however, has been
subject to recurrent exogenous disruptions in the form of geopolitical shocks,
financial crises, and regulatory interventions (or lapses). The Great Depression
of the 1930s and the great inflation of the 1970s stand out as times of
major discontinuity, along with “mass extinctions” such as the bank panics
during the 1930s and the savings and loan crisis in the 1980s.
Could something similar happen in our time? Certainly, the sharp
change in credit conditions in the summer of 2007 created acute problems
for some hedge fund strategies, leaving the funds vulnerable to redemptions
by investors. But a more important feature of the recent credit crunch
has been the pressure on banks.
More than $60 billion in write-downs has so far been acknowledged by
the world’s leading banks, but it is widely assumed that as much as $300 billion of subprime-related losses will eventually come to light. Pressure is
mounting on some banks to bring the assets of other novel organisms—
conduits and strategic investment vehicles—back on to their balance sheets.
Yet the difficulty of pricing these assets in highly illiquid markets and the
need to maintain capital adequacy are making this easier to say than to do.
In Europe, for example, average bank capital is now equivalent to less than
10 percent of assets, compared with around 25 percent toward the beginning
of the twentieth century. Some banks must sooner or later choose
between increasing their capital and restricting their lending.
And what of the market for mortgage-backed securities? Recent events
have certainly checked the hopes of those who believed that the separation
of risk origination and balance sheet management would distribute risk
optimally throughout the financial system. The U.S. asset-backed issuance
has collapsed since August, as has the issuance of collateralized debt obligations,
another relatively novel financial life form.
Nevertheless, the problems of the banks are opportunities simultaneously
for some big hedge funds, particularly those that seized the moment
to go public when stock markets were buoyant, and for sovereign wealth
funds, which are acquiring stakes in big-brand banks at what seem like bargain
prices.
A REGULATED SYSTEM
There is, however, one big difference between nature and finance. Whereas
evolution in biology takes place in the natural environment, where change
is essentially random (hence Oxford biologist Richard Dawkins’s image of
the blind watchmaker), evolution in financial services occurs within a regulatory
framework, where—to borrow a phrase from anti-Darwinian creationists—“
intelligent design” plays a part.
The financial equivalent of evolutionary success—that is, passing on your
genes—is being good at generating returns on equity and generating
imitators.
Sudden changes to the regulatory environment are rather different from
sudden changes in the macroeconomic environment, which resemble environmental shifts in the natural world. The difference is that there is an element
of endogeneity in regulatory changes because those responsible are
often “poachers turned gamekeepers,” with a good insight into the way that
the private sector works. However, the net effect is the same as climate
change in biological evolution. New rules and regulations can make previously
good traits suddenly disadvantageous. The rise and fall of the savings
and loans institutions, for example, was due in large measure to changes in
the regulatory environment in the United States.
The possibility of extinction cannot and should not be removed by
excessively precautionary regulation.
The primary focus of most financial regulators is to maintain stability
within the sector, thereby protecting the consumers whom banks serve and
the economy that the industry supports. Companies in nonfinancial industries
are neither so fundamental to the economy nor so critical to the livelihood
of the consumer. The collapse of a leading financial institution, in
which retail customers lose their deposits, is an event that any regulator
(and politician) wishes to avoid at all costs—a fact of which the British
authorities were painfully reminded by the run last summer on Northern
Rock, a mortgage bank.
An old question that has raised its head once again in recent months is how
far implicit guarantees to bail out banks create a problem of “moral hazard,”
encouraging excessive risk taking on the assumption that the state will intervene
if an institution is considered too big to fail (meaning too politically sensitive
or too likely to bring a lot of other companies down with it). From an
evolutionary perspective, however, the problem looks slightly different. It is,
in fact, undesirable to have any institutions in the category of “too big to fail”
because, without occasional bouts of what Harvard economist Joseph Schumpeter
termed creative destruction, the evolutionary process will be thwarted.
Japan’s experience in the 1990s stands as a warning to legislators and regulators
that an entire banking sector can become a kind of economic dead hand
if institutions are propped up despite underperformance.
Every shock to the financial system must result in casualties. Left to itself,
“natural selection” should work fast to eliminate the weakest institutions in the market, which typically are devoured by the successful. But most crises
also usher in new rules, as legislators and regulators rush to stabilize the system
and protect the consumer/voter. The critical point is that the possibility
of extinction cannot and should not be removed by excessively
precautionary regulation.
As Schumpeter wrote more than seventy years ago: “This economic system
cannot do without the ultima ratio of the complete destruction of
those existences which are irretrievably associated with the hopelessly
unadapted.” Creative destruction, in his view, meant nothing less than the
disappearance of “those firms which are unfit to live.”
The coming months will determine how far, in terms of economic
impact, the current crisis is a true ice age as opposed to just a severe winter.
It will also determine which among the world’s financial groups are the
dinosaurs and which are the fittest mammals.
