"I am continually amazed at the amount of nonsense that I’ve been
reading on the subject of moral hazard. Here are a few examples:
1. Moral hazard played no role with SVB because the shareholders and bondholders were wiped out. (nonsense)
2. Moral hazard isn’t an issue because average people don’t think about the safety of a bank when making deposits. (nonsense)
3. Moral hazard isn’t an issue because average people are unable to evaluate the risk of various banks. (wrong)
4. A run on bank deposits could cause a recession. (wrong)
If you see anyone making the first two arguments above, just stop
reading. They literally do not know what moral hazard is. The fact
that a business failed and the owners lost everything has no bearing on
the issue of moral hazard. Here’s Matt Levine:
Schematically, a bank consists of shareholders taking
$10 of their own money and $90 of depositors’ money and making some
bets (home loans, business loans, bond investments, whatever) with that
combined pile of money. If the bets pay off, the shareholders get the
upside (the depositors just get their deposits back). If the bets lose,
the shareholders lose money (the depositors get their money back before
shareholders get anything). If the bets lose really big — if the bank
bets $100 and ends up with $50 — then the shareholders lose all their
money, but the depositors get their money back: If the bank is left with
only $50, the government gives the depositors the other $40.
If you are a rational bank shareholder (or, more to the point, a bank executive who
owns shares and gets paid for increasing shareholder value), this
structure encourages you to take risk. If you bet $100 on a coin flip
and you win, the bank has $200, and the shareholders keep $110 of that, a
1,000% return. If you lose, the bank has $0, and the shareholders lose
$10 of that, a -100% return. The expected value of this bet, for the
shareholders, is positive. The expected value for the depositors is
neutral: Either way they get their $90 back, either from the bank or
from the government. The expected value for the government is negative:
If the bank wins, the government gets nothing; if the bank loses, the
government pays the depositors $90. But the shareholders — really the
executives — are the ones who get to decide what bets to take.
Deposit insurance gives bank executive an incentive to take socially
excessive risks. In some cases the risks won’t pay off. But that
doesn’t mean executives don’t have an incentive to take excessive
risks.
Things didn’t pan out for SVB. But that doesn’t mean their
executives made an unwise gamble. It’s very possible that SVB’s
strategy had a very high expected payoff, and they were simply hit by
bad luck (rising interest rates.) Of course from a social perspective
their decisions may have been bad, but not necessarily from a private
perspective. “Heads I win, tails part of my losses are borne by
taxpayers”. Of course I’d take more risk with those odds.
And yet despite this clear explanation of how moral hazard works,
Matt Levine follows a description of how SVB went bankrupt with this
head scratcher:
And so the question is: Is that moral hazard? Well, not for shareholders and executives and bondholders.
No! The fact that things didn’t work out for the executives doesn’t
have any bearing on the question of whether moral hazard distorted
decision-making at SVB.
The second misconception above also illustrates a basic lack of
understanding of moral hazard. Yes, people don’t tend to pay attention
to bank balance sheets when making decisions on where to put their
money. But that’s exactly what you’d expect to happen if moral hazard
were a major problem. People would stop caring about bank risk, and
highly risky banks would understand that they could attract deposits
every bit as easily as conservative, well-run banks. Clueless
depositors are not evidence of a lack of moral hazard; they are evidence that moral hazard exists.
At this point people often shift their argument. They say, “Yes,
it’s unfortunate that depositors don’t discipline banks, but you
certainly cannot expect average people to evaluate the safety and
soundness of large complex banks.” Really? Are these claims also true?
1. Most average people don’t read academic papers and attend lectures
at lots of universities, hence you cannot possible expect average
people to know that Harvard and Stanford are better that South Dakota
State and Western Michigan University.
2. Most people are not able to evaluate the quality of carburetors,
anti-lock brakes, and fuel injection mechanisms, so they couldn’t
possibly be expected to know that a Mercedes is better than a Ford.
3. Most people are not able to evaluate the quality of surgeons, so
they cannot possible be expected to know that Johns Hopkins is better
than Missouri Valley Hospital.
Yes, modern Americans pay little or no attention to the relative
safety of various banks. Why should they? But I assure you that back
in the 1920s people cared a great deal about bank safety. Banks knew
this, and managed their balance sheets far more conservatively than do
modern banks. That’s why big city banks used to look like massive Greek
temples; they had to convince depositors that they had the capital to
survive hard times. The vast majority of big banks survived the Great
Depression. US GDP in 1929 was about $100 billion and deposit losses
during the Great Depression were $1.3 billion. Today, a 50% fall in
NGDP (as in 1929-33) would wipe out almost our entire banking system.
Modern bankers are far more reckless “despite” regulation. The negative
effects of deposit insurance are far more important than the positive
effects of regulation.
When people think about moral hazard, they often exhibit a lack of
imagination. If you read a great deal of history, you often find
yourself asking, “How could people have behaved that way? What were
they thinking?” Take an example from the 19th century. One aristocrat
insults another at a well-attended dress ball. How would you react?
Now think about how you would react if you had been born in 1820. You
might respond to the rude comment with a challenge to a duel. Pistols
at 20 paces, 6am the following morning. We can’t imagine living this
way, because we never experienced this world.
A world without deposit insurance is not that far away. When I was
10 years old (1965), Canada had no deposit insurance and got along just
fine. People who live in that sort of world know how to behave. They
know enough to put their money in safe banks, not reckless banks. I
wish Canada had never adopted deposit insurance. (I suppose their
decision to do so represented the misguided big government liberalism of
the late 1960s.)
Of course, the US system is much different from the Canadian system.
Prior to FDIC, we had lots of bank failures. This was due to the
almost incredibly undiversified nature of our system, which resulted
from some pretty insane branch banking restrictions. Here’s Elmus Wicker:
The number of commercial banks in the United States nearly tripled
during the first two decades of the 20th century, reaching 30,000 in
1920. The vast majority of these were unit banks as required by their
national and many state charters. Illinois had nearly 2,000, and
Nebraska, with a population of 1.3 million, had a bank for every 1,000
residents. Failures averaged about 70 banks per annum, or one of every
300 existing banks, during those two decades. The agricultural
depression of the 1920s raised the failure rate to more than 600 banks
per annum, or one of 50. Failures showed few signs of abating as the
decade drew to a close, and the banking system, especially in rural
America, entered the Great Depression in a fragile state.
LOL at Nebraska. Given the large size of families back then, that’s roughly one bank for every 250 families!
Contrary to widespread opinion, (even among many economists), the
bank failures of this period did not lead to much contagion. The only
real “panic” occurred for entirely different reasons, when there was
(well-justified) fear that the US would leave the gold standard.
Otherwise, lots of inefficient small banks failed and life went on.
The Canadians were much smarter. They allowed large well-diversified
banks, and thus have looked on with bemusement as the US reels through
one banking crisis after another. Here’s the Financial Post:
Despite investor jitters, concerns for the Big Six were limited.
Unlike SVB, which catered to a niche market funding tech start-up
companies, Canada’s big banks dominate their home market and are
diversified across industries and business lines.
“From a Canadian perspective, not only should the failure of SVB not
have significant negative implications for our banks, but this crisis
should actually be viewed as further vindication of the Canadian banking
model, which is dominated by a few large and diversified players,” Bank
of Nova Scotia analyst Meny Grauman said in a March 13 note.
In the US, both left and right wing politicians favor the smaller banks. Big is viewed as bad. Matt Yglesias is one of the few progressives that understands the value of big banks, and today he has an excellent post on the issue:
The moral of Silicon Valley Bank’s collapse is that the real danger comes from the medium-sized ones
How do we get to Yglesias’s utopia? Abolish deposit insurance (he
wouldn’t agree). You’ll see a massive shift of deposits toward the
larger, more diversified banks, making our system resemble the Canadian
system.
Most people, and even most economists, know nothing about our banking
history. They’ve never bothered to read Elmus Wicker, Larry White,
George Selgin, or any of the other experts. They get their ideas from
films like “It’s a Wonderful Life.” They view our banking system as a
fragile house of cards that would collapse without FDIC. (Funny how the
Canadian house of cards avoided any major problems in the century
before 1967.) Actually, it’s a house of cards created by FDIC.
The final misconception involves the effect of banking crises on the
macroeconomy. It’s true that banking crises are often associated with
recessions, but not always. Industrial production soared 57% between
March and July 1933, despite many of America’s banks being shut down to
check their balance sheets. In fact, in a fiat money system causality
generally goes from the business cycle to banking distress, not the
other way around. The US entered recession in December 2007. The
recession got much worse after June 2008. The banking crisis occurred
in late September 2008.
As long as the Fed adjusts monetary policy to keep expected NGDP
growth at a healthy level, bank failures should have no significant
impact on economic growth. In any case, creating moral hazard doesn’t
prevent banking crises, it simply pushes the problem into the future.
FDR opposed deposit insurance, as he (correctly) feared it would
create moral hazard. Unfortunately, Congress refused to listen to his
good advice.
PS. Some other misconceptions:
“FDIC fees are not a tax on the public.” Yes, they are.
“We aren’t bailing out bank executives”. No, we are not bailing out
SVB executives, but we are (implicitly) bailing out their competitors."
