I think we're now ready to tackle the big picture and
[3]
what has our government officials so
[7]
worried right now.
[7]
So what I've done is, I've just drawn the balance sheets
[11]
for a bunch of banks.
[12]
Obviously, this is simplified.
[13]
And I made all of their balance sheets look the same.
[15]
All of these banks, each of these kind of represents the
[17]
balance sheet of a bank.
[18]
And just to explain it, the left-hand side of this balance
[20]
sheet, so this column right here-- and maybe I can, at
[24]
least for the first bank, mark it a little bit.
[27]
So what I'm squaring off in magenta, that's the
[35]
assets of that bank.
[39]
What I'm squaring off in blue, that's the
[44]
liabilities of the bank.
[45]
And what I wrote here is, it has $4 billion of liabilities.
[47]
Its assets, I divided it between $3 billion of other
[51]
assets and $2 billion of CDOs.
[54]
Because we want to focus on the CDOs, because that's the
[56]
crux of everything that's going on.
[58]
And we have $5 billion in assets, $4 billion of
[60]
liabilities, so you have $1 billion in equity.
[62]
So that's what's left there.
[63]
So this is just another visual representation that
[66]
liabilities plus equity is equal to assets.
[70]
Or assets minus liabilities is equal to equity.
[75]
And I've just copied and pasted this one balance sheet
[77]
a bunch of times.
[78]
I don't know whether we're going to use all those.
[81]
But let's just assume, for simplicity, that a ton of
[84]
banks in the system have this identical balance sheet.
[86]
Obviously, they don't have an identical balance sheet.
[88]
But all of their balance sheets might have kind of
[91]
similar properties.
[97]
This isn't always the case, different banks have different
[99]
exposures to CDOs.
[101]
Some of them have a lot, some of them have a little bit.
[103]
Some of them are valuing them more
[105]
conservatively than others.
[106]
But just for the sake of simplicity, I've just made all
[108]
the banks in the situation where the book value of the
[112]
CDOs that they have on their balance sheets is the larger
[115]
than their equity value.
[117]
And I did that for a reason.
[119]
Because it leads to the issue of, are these banks facing
[122]
just a liquidity issue or are they facing
[125]
just a solvency issue?
[127]
If you believe that these are worth $3 billion, these
[130]
assets, these liabilities are worth $4 billion, then the
[133]
crux of whether it's a liquidity or a solvency issue
[136]
all falls down as to whether these are worth
[139]
$2 billion or not.
[140]
For example, if these are worth $2 billion, then you
[142]
have $1 billion of equity.
[144]
If these are worth $1.5 billion, well maybe they're
[147]
being a little optimistic here, but you'll still have
[149]
$0.5 billion of equity.
[150]
So you're still solvent.
[153]
And in that situation, in theory, one is just if they
[158]
don't have the cash when some of their debt comes due, they
[160]
should just be able to borrow some money and
[163]
get past that hurdle.
[164]
And then in the future maybe sell their assets and still
[167]
have positive equity.
[168]
However, if the true value of those CDOs, and this is kind
[172]
of a philosophical question, what's the
[174]
true value of anything?
[176]
And the best thing that we as humans have been to be able to
[178]
come up with is a market.
[181]
The market value tends to be the best representation of the
[184]
true value of something.
[187]
Let's say the true value of this is $1 billion or less,
[190]
then we have a situation.
[191]
For example, if these are worth nothing, then we only
[193]
have $3 billion of assets, $4 billion of liabilities, we
[197]
have negative equity.
[198]
This company is worth nothing.
[199]
And to lend this bank or this company any money would just
[203]
be throwing good money after bad.
[204]
Because that money is just going to go into a black hole.
[207]
Because one of the people who this company owes money to is
[211]
probably not going to see their money.
[212]
And if you are the most junior person lending the money--
[215]
which means that when all the money is distributed if they
[217]
go into bankruptcy, you're the last person to see the money--
[220]
then you're just throwing good money after bad.
[222]
So that's the issue.
[223]
But I want you to see the big picture now.
[225]
Because if it was just an issue with one bank it
[227]
wouldn't be a big deal.
[228]
If it was just Bear Stearns or if it was just Lehman
[231]
Brothers, not a big deal, let the
[233]
greedy bankers go bankrupt.
[234]
And they probably are doing just fine with the bonuses
[238]
they've collected after sourcing these CDOs for the
[241]
past eight years or five years or however long.
[245]
But what I want to show you in this video is what people are
[248]
talking about when they say systemic risk.
[251]
So these $4 billion in liabilities, these are loans,
[256]
maybe from other banks.
[257]
In fact, probably from other banks.
[259]
And those loans from other banks, those are assets of
[263]
other banks.
[263]
For example, let's say this is Bank A, this is Bank B.
[269]
Maybe a billion of these are a loan from bank B.
[276]
And if this is a loan from Bank B, Bank B would have an
[279]
asset called loan to Bank A.
[283]
On Bank B's balance sheet we're calling this a
[285]
loan to Bank A.
[287]
This is one of its assets.
[288]
And then one of its liabilities will be a loan
[290]
from Bank B.
[292]
So how can I say this?
[294]
They took this money and they gave it to B.
[297]
I'm sorry, B had money, gave it to A in the form of a loan.
[301]
And so that cash ended up here.
[303]
And they got an asset called loan to Bank A.
[307]
And this is a liability, loan from Bank B.
[309]
And they might have taken that money and they might have lent
[312]
it to Bank C down here.
[316]
I think you're starting to see how this gets pretty hairy
[321]
very fast. So let's say that Bank A, one of its $3 billion
[326]
in assets, is a loan to Bank C.
[337]
And so on Bank C's balance sheet, it'll say
[342]
loan from Bank A.
[344]
Or so we owe A $1 billion.
[347]
And A says, C owes me $1 billion, and that's all fine.
[350]
And then you see that oh, we owe B $1 billion.
[352]
And then we could keep doing this.
[354]
Or I could just even make this into a circle already.
[357]
So maybe Bank B has some money that it owes to someone else.
[360]
And let's say that someone else, just for fun, just to
[363]
make this interesting-- I think you can extrapolate and
[368]
think about how this gets complicated very fast. Bank B
[371]
has borrowed money from Bank C.
[372]
So Bank C will have an asset here that says, no I lent
[375]
money to Bank B.
[382]
Fair enough.
[384]
OK, so now we're in an interesting situation.
[387]
Let's say this loan, the loan from Bank B to
[391]
Bank A comes due.
[392]
And we've studied this multiple times.
[399]
And let's say for whatever reason, all of these other
[401]
loans, they're not liquid.
[403]
They're not due yet.
[405]
So Bank A can't get rid of these loans.
[411]
So let's say this comes due, this is $4 billion.
[413]
They can't sell any of this.
[415]
So Bank A has to come up with $1 billion somehow for Bank B.
[421]
So that's the situation we're dealing with.
[423]
I'm just going to say that they can't sell
[425]
any of these assets.
[426]
So it all comes down to the CDOs.
[427]
So there's a couple of issues here.
[429]
If you think it is just an issue of illiquidity, if these
[432]
are $2 billion of assets, they're really worth $2
[435]
billion, but Bank A just can't sell them.
[437]
Because either there's quote-unquote
[439]
nobody willing to buy.
[440]
Although, I would argue if no-one is willing to buy
[442]
something, then its true value is probably zero.
[445]
But let's just say Bank A says no-one is willing to buy,
[448]
we're just illiquid, this is really worth $2 billion.
[450]
So one situation is they could get a loan from someone.
[453]
Maybe the Fed would be willing to take this as collateral.
[456]
So they would give this as collateral to the Fed.
[458]
Maybe the Fed will give them a billion dollar loan.
[460]
And then they can use that to pay Bank B.
[463]
Let's say that's off the table because this is just smelly
[467]
enough collateral that not even the Fed, which we now
[470]
realize is willing to do anything to support the
[471]
markets, not even the Fed is willing to give them a loan.
[474]
Or enough of a loan to pay off that loan.
[477]
The other situation is maybe they can get an equity
[480]
infusion from a sovereign wealth fund.
[481]
And we covered that a couple of videos ago.
[483]
Where the sovereign wealth fund will
[484]
essentially inject some cash.
[486]
It'll dilute the shares and then you know maybe we had 500
[489]
million shares before.
[490]
Now we'll have 2 billion shares.
[491]
So the sovereign wealth fund will take over roughly 80% of
[497]
the company.
[497]
And in exchange for 80% of the company, would give maybe $2
[500]
billion and then you could use that to pay off this loan.
[503]
But let's say that that's not on the table anymore either.
[507]
Because the sovereign wealth funds have
[508]
gotten burned so much.
[511]
So what happens?
[511]
Well we learned what happens.
[513]
If you can't get a loan, a new loan, to replace this loan, or
[517]
if you can't get an equity infusion from kind of a
[519]
greater fool, what happens?
[520]
You go into bankruptcy.
[522]
And this is what happened to Lehman Brothers.
[525]
Lehman Brothers went into bankruptcy.
[526]
No sovereign wealth fund, no one else bought the company.
[529]
And I should probably do another
[529]
video on that scenario.
[531]
And they couldn't get a loan.
[532]
So they went bankrupt.
[533]
I should call this Company L actually.
[535]
But I'll call it Company A for now.
[536]
Because I don't want to impugn anyone.
[539]
I actually don't think Lehman was any worse or better than
[542]
any of the other players here.
[544]
So when they go into bankruptcy, something very
[547]
interesting happens.
[549]
Now, Bank B, they were already worried about these CDOs.
[553]
These CDOs were already an issue.
[554]
And they were probably thinking, boy when when Loan C
[557]
comes due, I'm going to be in trouble.
[558]
Or when Loan D, or F, or whatever, I'm going to be in
[562]
trouble because I'm going to be in that situation that I'm
[565]
essentially forcing Bank A into right now.
[567]
But now I have a new problem.
[569]
This loan to Bank A isn't getting paid off.
[576]
And who knows?
[577]
Bank A is going to go into bankruptcy.
[580]
Maybe in bankruptcy we realize that these are worth nothing.
[584]
And if those are worth nothing, then maybe I'm very
[588]
junior in seniority in terms of where my loan is and maybe
[592]
I get nothing.
[593]
Or I get a few pennies on the dollar here.
[594]
So maybe I thought this was $1 billion and I have to write
[597]
this down to $0.5 billion.
[600]
So now I have two problems. I have this and I have this.
[603]
And once again, this is a non liquid loan.
[606]
Bank A is in bankruptcy.
[608]
And if I wanted to somehow get the value of this I have to
[611]
wait for all of Bank A's assets to go into liquidation.
[614]
And then whatever assets I get I would have to sell it.
[617]
So this is kind of a frozen asset.
[619]
So once again, I'm stuck holding this non liquid asset.
[622]
So now I have this non liquid asset that's probably not
[624]
worth what I thought it was, which was a loan to A.
[626]
Then I also have these CDOs.
[629]
And now, God forbid, let's say that I had another
[635]
loan to Bank D.
[638]
And now let's say Bank D goes bankrupt.
[640]
And then I have another loan that's bad on
[642]
top of these CDOs.
[643]
But the CDOs were the crux of the issue.
[645]
That's what caused the situation.
[646]
If Bank A could have only sold this CDO for $2 billion, it
[651]
wouldn't have caused this chain reaction.
[654]
And Lehman Brothers really was the thing that catalyzed this
[659]
whole chain of events.
[662]
And then you can imagine now Bank C is worried because now
[664]
Bank B has all of these illiquid assets on top of
[667]
these CDOs and it starts to look bad.
[668]
And you can imagine, now it's even less likely that when a
[672]
bank, let's say that Bank D is the next one to go into a dire
[675]
situation, it's even less likely that Bank D can get a
[678]
loan from a third bank.
[680]
Because all the banks are getting scared now.
[682]
All the banks are saying, I'm not going to
[683]
loan money to anyone.
[684]
If I can get any cash from anybody I'm just
[685]
going to keep it.
[686]
So that when it's my turn, when the market starts looking
[689]
at me, I at least have a little cash.
[691]
So everyone is frozen.
[692]
Everyone wants to collect their loans from everyone else
[695]
and no one wants to give loans to anybody else.
[698]
So that's the situation we're in.
[700]
And that's the difficulty that the Fed is
[703]
somehow trying to unwind.
[705]
And I realized I'm out of time again.
[706]
I will confront that issue in the next video.
