- If the notes (money) does not represent the gold anymore, what does the Fed still "owe" to us in that IOU note? Hence, can we say otherwise then about money? I just thought if when I got through the video somewhere at... 3:46(8 votes)
- The IOU's Sal is talking about do not pertain to the dollar bills in your wallet. The IOU's mentioned are from loans between the Fed and the banks it does business with.
The Fed owes you nothing for a Federal Reserve Note. Federal Reserve Notes are a fiet currency, the reserve notes are not an IOU, they have no redemption value with the reserve, they are only worth the value of the goods or services you can trade them for.(6 votes)
- Sal forgot about the bank where he wrote "100" what about that bank?Is bank 4 bank100????I don't understand!
(I'm only a kid!). (with an iPad.............) @@
-(3 votes)- Sara, you are a very smart kid! That bank is included in his example. Sal got a little ahead of himself. He is just trying to demonstrate the "domino effect" of how one bank can fail after another. Hint: Use the closed captioning even if you are not hearing impaired as that helps reinforce what Sal is saying and also helps with spelling. Keep up the great work, Sara!(15 votes)
- when the FDIC gets fees for insuring banks, where does that money go? The treasuery? Back into the federal reserve?(4 votes)
- Daniel, the majority of the insurance premiums collected from banks and thrift insititutions are invested in U.S. Treasury Securities. A small portion goes to paying the staff and operating expenses of the FDIC.(2 votes)
- So when times are bad we would have to pay(trough taxes) for our own money,right?(5 votes)
- yes because the FDIC gets money though taxes. so if there is a financial crisis taxes would have to be used to pay the deposits. You would also be paying for others so it is a very good idea to invest in a bank account.(0 votes)
- what is the difference between federal reserve note and federal note outstanding? is note outstanding the same as cash? if so, why atSal said that Fed lend out money to member banks by giving them FRN? because if I want to withdraw my money, I would want cash and not US Treasuries notes.. 6:10(2 votes)
- Cash = Federal Reserve Notes. Paper currency in the US used to be issued by congress but now it is issued by the Fed (a private corporation). These 'dollars' are actually called Federal Reserve Notes because they are notes from the Federal Reserve. You would not withdraw treasury notes as those are an investment like T-Bills or T-Bonds (the difference between the three is only the duration to maturity).(4 votes)
- Wouldn't the banking system be more sound without FDIC insurance? Without deposit insurance people would actually care and take time to look into where they are throwing their money. In addition, banks would be forced to compete for deposits and draw people in with an interest rate appropriate to the level of risk desired by the depositor.
Why not allow the private sector to supply depositors with deposit insurance if they want it?(2 votes) - Why do we assume that FDIC insurance is underpriced? If financial insurance is difficult to price due to correlations, isn't it just as likely that the FDIC insurance is overpriced?(2 votes)
- I see that the FDIC undercharges the big banks for the insurance, and the safety net it offers the banks encourages them to take on additional risks to outcompete other banks. In this type of environment, might it be a good idea to adopt a fluctuating premium, where the costs of FDIC insurance go up for a bank that is increasing risks, and down for a bank that is decreasing risks?(2 votes)
- In a perfect world your example seems pretty logical. Unfortunately there are a lot of problems with such a system.
First of all, major problems are never evident until after the fact. The last recession is a perfect example of that. So coming up with a way to judge such risks may be impossible. Also, the government is dreadfully outmatched in such circumstances. It would take a team of 25+ people working full time just to adequately stay on top of one of the six largest banks. Those kinds of resources just aren't going to happen. Even the for profit ratings agencies can't compete. I remember hearing that leading up to the last recession the ratings agencies each only had a team of about 5 people covering the entire banking sector.
Also, the line of who qualifies for FDIC insurance is getting really blurry. Banks that don't carry much in the way of deposits (Morgan Stanley, Goldman Sachs) are now able to tap into FDIC insurance, when previously they wouldn't have qualified.(2 votes)
- I understand that if people deposit their own money that they should be able to expect to withdraw it whenever they want, but that's offset by actual reserves. It seems to me that for a bank run to happen most of the people coming to withdraw their gold are the people with loans and it was never really actually their money to begin with. If the problem is the money the banks lends out itself then why doens't it just make it a condition of the loan that you can't withdraw all of it at once?(2 votes)
- the bank only has to keep 10% of the money, so you can only withdraw that much at any given time, i think(1 vote)
- When Sal talks about reserves of the bank being depleted, in modern times what are those reserves? Clearly gold is out, so is Sal talking about Cash? What constitutes the reserves of modern banks?(1 vote)
- Reserves are just any deposits that the bank has taken in that it hasn't lent out. Those funds may be placed on deposit at the fed, or invested in treasury securities, or held in cash in the vault, or invested in some other way, depending on what the bank's overall reserve ratio is and what laws govern it.(2 votes)
Video transcript
In the last video, I touched
on the core weakness of fractional reserve banking and
that's the idea of the bank run-- where if you have a bunch
of banks and they've all lent out 90% of their reserves--
let's say that here's all my banks-- Bank One,
Bank Two, Bank Three-- and you could have
a ton of banks. I mean, you could imagine you
go all the way to Bank 100. The problem with a bank run is
if just even one bank all of a sudden isn't able to give its
depositors its money-- so it is illiquid-- and we'll reserve
judgment as to whether it is truly insolvent, but it
really just doesn't have the money to give it to depositors,
then all of the depositors of all of the other
banks get scared and run over to the banks and ask for
their money back. And by definition, in a
fractional reserve banking system, these guys only have
10% of their deposits as reserves, 10% reserves. So if more than 10% of the
people ask for their money, they're all going
to be illiquid. Then you're going to have
just an all-out panic. You're going to have
an all-out panic of the financial system. As soon as any of these guys'
loans come due-- so let me draw one of their balance
sheets-- let's assume that they were actually good
investors, which is a big assumption, but let's say
that their balance sheets look like this. Here's all of the deposits that
they owe to people-- to me and you. That's their liabilities. They have 10% of their assets
as actual currency reserves. And then the rest is loans
out to businesses and whatever else. And that's an asset because
businesses owe them something. And what's going to happens--
as soon as there's a panic, everyone wants their
money out. The reserves are depleted
very quickly. And then these guys sit there
waiting for their money. Essentially it shuts
down the bank. As soon as these loans mature--
maybe this guy owed his money in a year. Then they're going to say, just
give me the money back. I'm not going to renew the loan
even though you have a good business. And so everyone's going to want
their money back and the whole financial system's going
to break down and credit is going to freeze. And this is a huge problem. Remember, this could be just
because by one bad actor who couldn't manage their
liquidity properly. Even worse, it could be caused
just by one panicky withdrawer. There's doesn't even have
to be a bad actor. It could just be some fear that
enters the system-- and even for a completely legitimate
bank-- and I'll use legitimate in quotations
because we're assuming legitimate-- because some
would debate whether fractional reserve banking
is legitimate. But even if this is a completely
up-and-up bank, if for whatever reason more than
10% of their deposits get scared, then all of a sudden
they'll be illiquid and you'll be in this all-out
panic condition. Now I talked in the last video,
some of the things that have been engineered to
fix this problem. So these are the fixes. The first one is to have a
banker of last resort, a lender of last resort. And that's our central bank--
or the Federal reserve bank. And they'll never run out of
reserves, because these reserves can be borrowed from
them and all these are, are IOUs from the Federal reserve. So what the Federal reserve
does-- and I've talked about this in the past-- let's say
that their balance sheet currently looks like this. Let's say that this is their
current liabilities. These are their current
assets. And their current
liabilities are essentially going to be IOUs. These are going to be their
reserve notes, but let's say someone else comes and says,
hey, federal reserve, lend me some money. So what they're going to do is
that they're going to print some-- so these are Federal
reserve notes. And then they're going to just
create an offsetting liability and they have no
reserve limits. Let me make it a new color just
to ease the monotony. So they'll have this
corresponding notes outstanding liability and
they're going to give those notes to you. They're going to give those
notes to the bank that's in a desperate situation if
it couldn't borrow from any other bank. And so the Federal reserve
balance sheet will now look like this. This is what it looked
like before. It has these new notes
outstanding and now this will say-- instead of federal reserve
notes in its vaults, it'll now have this little thing
on its books called loan to the bank, loan to this guy
right here, which is an asset because he owes him something. And there's no limit to
which the Federal reserve could do this. Obviously there might be some
kind of implicit limit. If they keep doing this
arbitrarily, people might not accept these Federal
reserve notes as actually carrying value. So that's probably the main
limiting concern. And I'll probably talk more in
future videos on other things that are kind of keeping the
Federal reserve from just doing this willy-nilly, but the
general idea is that they never run out. So this is one idea-- lender of
last resort, but not even the Federal reserve wants to
keep doing this because what if this guy is essentially
insolvent? If these loans are actually
going bad, then there's no reason that even the central
bank should actually be lending to this guy. They shouldn't be lending
to this guy. So let's say the Federal reserve
looks at this guy's books and say, you know what? These loans are really
worthless. I'm not going to lend
more money to you. What I'm going to do is take
you into receivership. And I haven't even talked
about what that is. That's the second fix. The second fix is to have this
notion of insurance, of deposit insurance. So if a bank just has a
liquidity problem-- it's a good bank-- it just ran out of
reserves and no other bank is willing to lend to it-- which
you might debate whether it's even a good bank if the other
banks aren't willing to lend to it-- then it can go to the
discount window at the Federal reserve and borrow some
reserve notes. Now, in the situation where even
that's not good enough and the bank is essentially out
of business, it had been paying the FDIC a little bit of
money-- the Federal Deposit Insurance Corporation-- a little
bit of money-- I mean, probably a lot of money by an
individual's point of view, but a little bit of money from
a bank's point of view-- and it's a fraction of a percent--
a little bit of money every year so that it could tell its
depositors, look, even in the situation that our bank goes
bust, the Federal reserve is going to pay you directly. These are FDIC bank accounts. The Federal reserve will make
you whole completely, regardless of what happens
to the banks. Now this, to me, is a big fix. I mean, I'll tell you right now,
all of my savings right now are in Federal deposit
insured-- FDIC insured-- bank accounts. This might sound great to the
depositor, but what's the side effect on the banking system? Let me draw all of
my banks again. So I have Bank One, I have Bank
Two, I have Bank Three, I have Bank Four. Now, they are all
FDIC insured. They pay some small fraction of
a percentage every year so that they can tell their
depositors, look, if we ever go bust, if we ever blow up
for whatever reason, your deposits are 100% safe. And what's going to happen? This will solve the bank
run problem, right? Let's say for whatever reason
this guy runs out of reserves or he goes bankrupt--
let's say that this guy goes bankrupt. In the old situation, before the
insurance, everyone else is going to get scared
and you're going to have a bank run. They're going to ask for their
money and there's just not going to be enough reserves
because they only keep a fraction of the reserves. That's what fractional reserve
banking is, but now everyone's going to feel comfortable,
like, you know what? Everything is backed by the
Federal reserve, which can print as many notes is
it wants so I'm just going to sit pretty. So this does solve the
bank run problem. And so you might say, this
doesn't make it an unstable equilibrium any more-- which
is kind of true, but what does this do? All of these guys are
now FDIC insured. I'm equally willing to give my
money to any of these guys. So I'm going to essentially
going to give my money to the guy who gives me the highest
interest. And I've actually done that with my personal
accounts. I've gone and I've seen which
bank provides the highest interest and I've ignored how
they're investing their money-- I mean, otherwise I'd
be pretty suspicious about a bank offering more interest
because they're probably doing something risky, but now I don't
care because I know it's FDIC insured and even if that
bank blows up, I'm going to get all my money back. So I might as well give my
deposit to the bank with the highest interest. Now based on what you saw in
that last video, which is the bank that's going to be giving
the highest interest? What's going to be
the bank that's taking on the most risk? So once again, when you give
this relatively cheap insurance to all of these banks
and all of these banks can attract money much easier by
paying this insurance-- if they didn't have this insurance,
they would have to pay much more. Let's say this insurance
is 0.1% per year. If they didn't have this
insurance, they would have to pay much more than 0.1% per
year to the depositor in interest to make up for the risk
that they're taking on, that they're not being backed
by the government. So it's a really good deal
for the depositor. Let's put it this way. When you give a deposit to
a bank, you're lending money to the bank. So your checking deposit rate--
so let me write this down-- your checking deposit
interest rate is the same thing as the bank's borrowing
cost, right? When I go to some bank and
they're paying me 2% a year, that's the bank's borrowing
cost. They're the same thing. Now if the bank didn't have FDIC
insurance, it wouldn't have to pay 0.1% a year, but it
would have to give me more interest. It would have to pay
me 3% or 4%, probably more, because I'd say this
is a risky bank-- or it's more risky. Any bank would be more risky
than someone who can print out the notes. So it would have to pay more,
but now it can just pay 0.1% a year or whatever the Federal
Deposit Insurance Corporation pays it, but it's going to lower
to FDIC, but the main side effect of this is it's
going to lower what it has to pay the depositors because the
depositors say, this is a lot safer than what I thought. So it's going to lower
borrowing costs by much more than 0.1%. So it's a really good deal
for the bank and it's an especially good deal for the
ultra-risky banks who might have to pay a little bit more,
but because they can now do super duper risky things. You say, hey, but this
is insurance. The Federal Deposit Insurance
Corporation isn't stupid. It should just charge more
for riskier banks. But I guess the rebuttal to
that is that's easier said than done because when times are
good, like in the '20s or during the housing bubble,
you get hidden risk. So you don't know who's
taking on the risk. It's usually the person who's
getting the highest returns, but if they're always good for
it, you don't see it and that person just looks
like a genius. And then when times are
bad, that guy blows up, but guess what? He's not on the line for it. It's the Federal Deposit
Insurance Corporation, who all along was probably undercharging for that insurance. I want to make one last
point about this. It's called insurance. It's the Federal Deposit
Insurance Corporation. And I want to point out the
difference between financial insurance-- and you could
watch my video on credit default swaps, which is another
form of financial insurance-- between financial
insurance and what we normally associate with insurance. If I have car insurance-- let's
say I'm a car insurance person and I agree-- let's say
that they are Driver One-- let's say I have a bunch of
drivers-- so Driver One, Driver Two, Driver Three,
Driver Four. And I know that in any given
year, they each have a 10% chance of an accident. That's a lot higher than
reality, but we'll make the numbers easy. And if there is an accident,
it will cost me $10,000. So I could go to Driver One and
say, look, there's a 10% chance you're going to
have an accident. It would cost $10,000
if you do. So I'm going to charge
you-- the fair price would be $1,000. I'll charge you $1,100. I'll charge $1,100 just so I
can make a little bit of a profit, right? What you would charge is $1,000
if you wanted to break even, but I'll charge $1,100--
and I might do this more than just four drivers. I might do it with
4,000 drivers. So on average in any given
year-- let's say I have one million drivers-- in any given
year, how much am I going to bring in? I'm going to bring in a million
times $1,100, which is-- I'm going to get $1.1
billion in input, or in revenue, from people paying
their premiums. And how much am I going to have to pay out? Well, roughly 10% if you believe
these statistics are going to have an accident. So that means that 100,000 are
going to have an accident. Each of those 100,000
accidents are going to cost me $10,000. $10,000 times $100,000. I'm going to have to pay out $1
billion for the accidents. So I will net every year-- if my
actuaries did their job, I will net $100 million
every year. And this works out pretty good
assuming these statistics are right and people are willing to
pay the premium because if you have enough drivers-- like
a million drivers-- the statistics really hold. In any given year, the chance
of 20% of the drivers having an accident is very,
very, very-- almost infinitesimally small. It's almost zero. And one driver having an
accident doesn't make it more or less likely that another
driver will have an accident when you're talking
about on the order of a million drivers. And that's true of health
insurance and everything else. It's just purely probabilistic
and if you have enough people insured, the statistics
can actually hold up. Now with financial
insurance, you have a different situation. You might say, look, in any
given year, on average, the FDIC might say, look, only-- I
don't know-- one out of out of 1,000 banks fail. So there's a 0.1% chance
of failure. Of course it'll capture back
some money because it'll have some assets on average. But the reality is that when
times go bad, the bank failures tend to be correlated
because they're all interlinked. And I've done a lot-- one
might be lending to some business that's dependent on
some business that this guy's lending to. The whole financial system
is all linked up. So the failures aren't-- they
all correlate with each other. They're not independent
events. So if one bank fails, it's much
more likely that other banks are going to fail all
at the same time and we're experiencing that right now. So you can't really follow the
insurance model because the statistics really don't apply. You can do this insurance model
when each of the events that you're insuring are
uncorrelated, but when all the events that you're insuring are
likely to all happen at the same time, what you're going
to have is-- when times are good, you're going to see a
much lower kind of loss rate and then when times are bad, all
of your guys are going to blow up and you're essentially
on the hook for all these people. We see that right now and the
FDIC is actually-- it's going to have to go back to Congress,
I'm 100% sure, and ask for more money and it's we
the taxpayers that are going to be on the line for
this type of thing.
