People often ask if regulators and legislators have fixed the flaws
in the financial system that took the world to the brink of a second
Great Depression. The short answer is no.
Yes,
the chances of an immediate repeat of the acute financial meltdown of
2008 are much reduced by the fact that most investors, regulators,
consumers, and even politicians will remember their financial near-death
experience for quite some time. As a result, it could take a while for
recklessness to hit full throttle again.
But,
otherwise, little has fundamentally changed. Legislation and regulation
produced in the wake of the crisis have mostly served as a patch to
preserve the status quo. Politicians and regulators have neither
the political courage nor the intellectual conviction needed to return
to a much clearer and more straightforward system.
In
his recent speech to the annual, elite central-banking conference in
Jackson Hole, Wyoming, the Bank of England’s Andy Haldane made a
forceful plea for a return to simplicity in banking regulation. Haldane
rightly complained that banking regulation has evolved from a small
number of very specific guidelines to mind-numbingly complicated
statistical algorithms for measuring risk and capital adequacy.
Legislative complexity is growing exponentially in parallel. In the United States, the Glass-Steagall Act of 1933 was just 37 pages and helped to produce financial stability for the greater part of seven decades. The recent Dodd-Frank Wall Street Reform and Consumer Protection Act
is 848 pages, and requires regulatory agencies to produce several
hundred additional documents giving even more detailed rules. Combined,
the legislation appears on track to run 30,000 pages.
As
Haldane notes, even the celebrated “Volcker rule,” intended to build a
better wall between more mundane commercial banking and riskier
proprietary bank trading, has been hugely watered down as it grinds
through the legislative process. The former Federal Reserve chairman’s
simple idea has been co-opted and diluted through hundreds of pages of
legalese.
he
problem, at least, is simple: As finance has become more complicated,
regulators have tried to keep up by adopting ever more complicated
rules. It is an arms race that underfunded government agencies have no
chance to win.
Even
back in the 1990’s, regulators would privately complain of the
difficulty of retaining any staff capable of understanding the rapidly
evolving derivatives market. Research assistants with one year of
experience working on derivatives issues would get bid away by the
private sector at salaries five times what the government could pay.
Around
the same time, in the mid-1990’s, academics began to publish papers
suggesting that the only effective way to regulate modern banks was a
form of self-regulation. Let banks design their own risk management
systems, audit them to the limited extent possible, and then severely
punish them if they produce a loss outside agreed parameters.
Many
economists argued that these clever models were flawed, because the
punishment threat was not credible, particularly in the case of a
systemic meltdown affecting a large part of the financial system. But
the papers were published anyway, and the ideas were implemented. It is
not necessary to recount the consequences.
The
clearest and most effective way to simplify regulation has been
advanced in a series of important papers by Anat Admati of Stanford
(with co-authors including Peter DeMarzo, Martin Hellwig, and Paul
Pfleiderer). Their basic point
is that financial firms should be forced to fund themselves in a more
balanced fashion, and not to rely so heavily on debt finance.
Admati
and her colleagues recommend requirements that force financial firms to
generate equity funding either through retained earnings or, in the
case of publicly traded firms, through stock issuance. The status quo
allows banks instead to leverage taxpayer assistance by holding
razor-thin equity margins, relying on debt to a far greater extent than
typical large non-financial firms do. Some large firms, such as Apple,
hold virtually no debt at all. Greater reliance on equity would give
banks a much larger cushion to absorb losses.
The
financial industry complains that efforts to force greater equity
funding would curtail lending, but this is just nonsense in a general
equilibrium setting. Nevertheless, governments have been very timid in
advancing on this front, with the new Basel III rules taking only a baby
step toward real change.
Of
course, it is not easy to legislate financial reform in a stagnant
global economy, for fear of impeding credit and turning a sluggish
recovery into a full-blown recession. And, surely, academics are also to
blame for the inertia, with many of them still defending elegant but
deeply flawed models of perfect markets that create an illusion of
safety for a system that is in fact highly risk-prone.
The
fashionable idea of allowing banks to issue “contingent capital” (debt
that becomes equity in a systemic crisis) is no more credible than the
idea of committing to punish banks severely in the event of a crisis. A
simpler and more transparent system would ultimately lead to more
lending and greater stability, not less. It is high time to restore
sanity to financial-market regulation.
