So let's see if we can get a
big picture of everything
[2]
that's happening in this credit
default swap market.
[6]
I'll speak in generalities.
[8]
Let's say we have Corporation
A, Corporation
[15]
B, Corporation C.
[20]
And let's say we have a bunch of
people who write the credit
[24]
default swaps, and I'll
call them insurers.
[26]
Because that's essentially what
a credit default swap is,
[28]
it's insurance on debt.
[31]
If someone doesn't pay the
debt, then the insurance
[34]
company will pay it for you.
[35]
In exchange, you're essentially
giving some of the
[38]
interest on the debt.
[39]
So let's say we have Insurer
1, let's say we
[45]
have Insurer 2.
[49]
And some of these were insurance
companies, some of
[51]
these were banks.
[55]
Some of these may have even
been hedge funds.
[58]
So these are the people who
write the credit default
[60]
swaps, and then there are the
people who would actually buy
[62]
the credit default swaps.
[66]
In the previous example, I had
Pension Fund 1, that was my
[69]
pension fund.
[70]
Then you could have another
pension fund, Pension Fund 2.
[76]
Let's re-draw some of the
connections between the
[81]
organizations.
[84]
Let's say Pension Fund 1 were
to lend $1 billion to A.
[92]
A will pay Pension Fund 1 10%.
[98]
But Pension Fund 1 wants to
make sure that they'll
[102]
definitely get the money,
because they can't lend money
[105]
to people with anything less
than stellar credit ratings.
[108]
So they get some insurance
from Insurer 1.
[111]
So what they do is out of this
10%, they pay them some of the
[114]
basis points.
[115]
So let's say they pay them
100 basis points.
[120]
And in exchange, they get-- I'll
call it Insurance On A.
[126]
This is this new notation
that I'm creating.
[128]
They get Insurance On A.
[130]
Fair enough.
[131]
And the reason why this I1, this
first insurer was able to
[135]
do that is because Moody's
has given them a
[137]
very high credit rating.
[139]
And so when they insure
something, you're essentially
[143]
the total package, right?
[145]
The loan to this guy, plus the
insurance, kind of is like
[150]
you're lending the money to
this guy, but you're just
[151]
getting more insurance-- I
mean you're getting more
[153]
interest, right?
[155]
So this bond becomes
a Double A bond.
[158]
Because the odds that you are
not going to get your money
[162]
are not the odds that this guy
defaults, but it's now the
[164]
odds that this guy defaults.
[166]
And Moody's or the standard is
poor, as I've already said.
[170]
Hey, these guys are good for
their money, they're Double A
[172]
or whatever.
[174]
So now your risk is really a
Double A risk and not a Double
[177]
B risk, or whatever.
[179]
But anyway, this happens.
[180]
This is Corporation B, and maybe
Pension Fund 2 wants to
[184]
lend to Corporation B.
[188]
Maybe they lend them
$2 billion.
[193]
They get, I don't know, they get
12%, maybe Corporation B
[196]
is a little bit more
dangerous.
[197]
But once again, they go
to this first insurer.
[200]
And maybe they get some of it--
well let's just say they
[203]
get Insurance On B.
[205]
And B is a little bit riskier,
so they have to
[207]
pay 200 basis points.
[209]
200 basis points goes from
Pension Fund 2 to B.
[213]
Now this, already, this is a
little bit dangerous, right?
[217]
Because you can think about
what's happening.
[219]
One, as long as this insurer
does not get a downgrade from
[223]
their credit ratings from S&P
or Moody's or whoever, they
[227]
can just keep it issuing
this insurance.
[228]
There's no limit for how much
insurance they can issue.
[232]
There's no law that says, you
know what, if you insure a
[235]
billion dollars of debt,
you have to put a
[237]
billion dollars aside.
[239]
So that if that debt defaults,
you definitely have that
[243]
billion dollars there.
[245]
Or if you insure 2 billion here,
you don't have to put
[247]
that 2 billion aside.
[248]
What you have is a bunch of
people who statistically say,
[251]
oh, you know, what's the
probability that all of this
[253]
debt defaults?
[255]
So I just have to keep enough
capital so that
[257]
probabilistically, whatever debt
defaults, I can pay it.
[260]
But you don't keep enough
capital to pay all of the
[263]
defaulting debt.
[264]
So you already see an
interesting risk forming.
[267]
What if all of these
corporations, for whatever
[270]
reason, do start defaulting
simultaneously?
[272]
Then all of a sudden this
insurance company has to pay
[276]
more out in insurance then it
might even have. So you have
[279]
to wonder whether it even
deserves this Double A rating,
[282]
because it actually is taking
on a lot of risk.
[284]
But in the short term, while
these companies are-- everyone
[287]
is doing well and the economy's
doing well, it's a
[289]
great business for these guys.
[291]
These guys are just collecting
premiums essentially on the
[293]
insurance, without having
to pay out anything.
[296]
Now let's add another
twist on it.
[299]
These pension funds, P1 and P2,
it was reasonable for them
[303]
to get insurance, because they
were giving out these loans
[306]
and then they got
the insurance.
[307]
So they were essentially hedging
the default risk by
[310]
buying these credit default
swaps, which was essentially
[313]
just an insurance policy
from this Insurer 1.
[316]
But you can have
another party.
[318]
This is no less legitimate,
really.
[320]
But you could call them-- I
don't know-- let's call it
[322]
Hedge Fund 1.
[327]
And they've done a lot of work,
and frankly, they often
[329]
are much more sophisticated
than the pension fund-- in
[331]
fact, they almost always are.
[333]
And they say, you know what?
[335]
Company B looks really, really,
really, really shady.
[339]
I think 200 basis points for
the chance that Company B
[344]
defaults is frankly cheap.
[346]
Because I think there's
a huge probability
[348]
that Company B defaults.
[350]
So what I'm going to do, I'm
not going to lend Company B
[352]
money, because if anything, I
think that they're maybe about
[355]
to go out of business.
[356]
But what I can do is I can buy
a credit default swap on
[359]
Company B's debt.
[362]
Which is, essentially, I'm
getting insurance that they
[364]
fail without actually
lending the money.
[367]
So let's say I do that
from Insurer 2.
[370]
So I can go and I'll pay Insurer
2 200 basis points a
[376]
year, or 2% on the notional
value of the
[380]
insurance I'm getting.
[382]
So let's say it's 200 basis
points, and let's say that's
[385]
Insurance On-- I'm making a big
bet-- so they're going to
[388]
give me Insurance On B for--
I don't know-- $10 billion.
[399]
And something interesting is
going on here already.
[402]
B might not have even borrowed
$10 billion, right?
[405]
So all of a sudden you have
this hedge fund that is
[408]
getting insurance on more
debt than B has even
[411]
borrowed money on, right?
[413]
And it's essentially, you just
kind of have this side bet
[415]
between these two parties.
[417]
This party says,
you know what?
[418]
I think it's a good deal.
[419]
I get 200 basis points on the 10
billion every year, as long
[423]
as B doesn't default.
[424]
And this guy says, I think
B's going to default.
[425]
So I think that's a good
deal on that insurance.
[428]
And just so you understand the
math, so the notional value is
[431]
$10 billion.
[432]
So what's 2% of 10 billion?
[435]
2% on a billion is 20 million,
so it's $200 million.
[443]
200 if I did my math correct.
[445]
So they'll pay $200 million
a year to this insurer.
[450]
So the 200 basis points
on 10 billion is
[453]
equal to 200 million.
[455]
These numbers maybe are a little
bit on the big side,
[456]
but who knows?
[457]
Actually, this could be
a huge hedge fund.
[460]
This could be a $10 billion
hedge fund.
[462]
Or even worse, maybe it's a
billion dollar hedge fund, or
[467]
maybe it's a $20 million hedge
fund, but they've taken a $180
[471]
million loan to essentially
buy this insurance because
[475]
they think that B's collapse
is imminent.
[478]
So they're willing to take
that bet right now.
[480]
You know, it might
be a good bet.
[482]
If B collapses tomorrow,
what's going to happen?
[486]
They only dished out maybe 200
million for maybe that first
[489]
year, although you normally pay
it on a quarterly basis.
[491]
So they'll pay 50 million
every three months.
[493]
Let's say they pay the first
payment, 50 million, right?
[496]
And then over the next three
months, B just goes bankrupt
[499]
and people realize that debt
was worth nothing.
[502]
Then these guys get
$10 billion.
[505]
Right?
[506]
But something else is
interesting here.
[508]
They probably did insurance to
a lot of other people too,
[510]
maybe on B's debt.
[513]
Right?
[513]
Or maybe they also
insured A's debt.
[518]
So maybe they gave
some insurance on
[519]
A's debt, as well.
[522]
So what happens?
[523]
Let's say B all of a
sudden defaults.
[529]
So a couple of things happen.
[532]
I1 is going to owe P2
$2 billion, right?
[537]
I2, the second insurer, is going
to owe this hedge fund
[540]
$10 billion.
[542]
Now let's just assume I2's
good for the money.
[546]
They have $10 billion they
pay to this hedge fund.
[549]
This hedge fund is great, they
get great bonuses for the year
[552]
and they go buy yachts,
et cetera.
[554]
But this insurer right here,
they pay the money they were
[557]
good for but something
interesting might happen.
[560]
All of a sudden Moody's finally
wakes up, these
[564]
ratings agencies, and
says, oh, my God.
[566]
Well, there's a couple of things
that might make them
[568]
say, oh, my God.
[569]
First of all, they might
say, oh, look.
[570]
You have to pay out
$10 billion.
[573]
And I doubt that was the only
person you have to pay, maybe
[575]
they have to pay out
a lot of money.
[576]
Now I2, Insurance Company 2,
you are undercapitalized.
[581]
I am now going to downgrade
your rating.
[585]
So, you were Double A, but since
you had to give out all
[589]
of this capital, Moody's is now
going to downgrade you to,
[593]
I don't know, B+.
[595]
I'm just making these
ratings up.
[597]
But that's the sound of how
these ratings happen, right.
[600]
A is better, B is worse.
[602]
The more A's you have,
the better it is.
[604]
But all of a sudden, when this
guy is B+, and this guy
[610]
insured, let's say, some other
corporation's debt for this
[613]
pension fund, now all of a
sudden this insurance that
[616]
this pension fund had is no
longer Double A Insurance.
[621]
It's now B+ Insurance, and maybe
this pension fund, by
[625]
its charter, can't hold
something that
[628]
has a B+ credit rating.
[630]
So they're going to have to
unwind the transaction, or
[632]
maybe they'll have to unload
the debt that was insured.
[636]
So one, just by Company B
defaulting, maybe this guy was
[642]
holding some of Company A's
debt, and it was insured by
[645]
Insurance Company 1.
[646]
Now they're going to have
to unload that debt.
[648]
So just one default creates this
chain reaction, right?
[652]
This one default happens, this
guy has to pay this guy money,
[656]
then this guy gets
undercapitalized since they
[658]
have to pay out money.
[659]
Then Moody's says, oh, my God,
you're undercapitalized.
[661]
We're going to reduce
your ratings.
[663]
Maybe this guy was insuring
some of A's debt, but now
[667]
since he was insuring some of
A's debt, all of a sudden that
[671]
insurance is worth less because
it has a lower rating.
[674]
And now A's debt, less people
want to hold it, because there
[678]
are less people to insure it.
[680]
I know that's very confusing,
but this is really the point
[683]
that Warren Buffett was saying
when he said that the credit
[687]
defaults swap market, or in
general, the derivative
[689]
market, are financial weapons
of mass destruction.
[693]
Because you have so many people
who didn't have to set
[695]
aside a capital, right?
[696]
This guy could insure $10
billion worth of debt without
[699]
having to set aside
$10 billion.
[701]
And you have so many people
making all of these side bets,
[704]
but they're all making
two core assumptions.
[706]
One, that these rating
agencies's ratings are valid.
[710]
And two, that the other person
is good for the money.
[712]
But if all of a sudden you have
one failure someplace in
[715]
the system, you could have
this cascade where one,
[717]
there's just a lot
of downgrades.
[719]
And then a lot of the people
end up not being
[721]
good for the money.
