This week: Dive deeper into one type of financial intermediary: Banks.
Next week: Sticking with macroeconomics, we’ll take a look at the next intermediary: Stock Markets.
Some people want to save and invest, others want to borrow. Sometimes, savers and borrowers link up directly. But most times, they don’t know each other. So they rely on institutions that bridge them together. These bridges are called financial intermediaries, and this video will show you one kind-banks.
How do banks operate?
On the savings side, they attract depositors by paying interest on deposits. On the borrowing side, banks make loans, for which they charge interest. The key to a bank’s profit is in charging a higher interest for loans than the interest paid out to depositors. Of course, to make sure that loans are as productive as possible, banks have specialized staff and systems for evaluating loan applications.
That sort of due diligence, and specialization is central to what a bank does. Not only does a bank coordinate the savings of many, but it also undertakes the task of studying borrowers in order to determine the most qualified. And then, to further minimize risk, a bank will spread its money out across a whole portfolio of loans. Thus, if one loan goes bad, the bank won’t go bankrupt.
In this way, you can see how banks provide valuable services-they allow you to earn interest on your savings, while also turning those savings into loans, which help economic growth.
Notice though, that as a depositor, your savings won’t just rest in a vault. But then, what happens when you decide to make a withdrawal? Banks account for that by having reserves. Banks keep an eye on their reserves so they can cover the withdrawals of various depositors. Predictably, problems arise, when there aren’t enough reserves to cover withdrawals. In the words of our previous video, that’s one kind of failed intermediation.
In the next video, we’ll look at a different kind of intermediary-stock markets.
There, we’ll show you how stock markets turn savings into investment. Hang tight, and see you then!

Deposit means nothing in law. It is a liability of the bank that you can swap with others. Loans create deposits. Every time bank loan 'money' they simply credit customers account (simply create new deposit). When you transfer this deposits, bank swap liabilities with each other at Fed Fund market, which is just an interbank obligations market. I am sorry to tell you but transfer of value by cash and coins only covers 3% of the circulations. Majority of settlements are done by trading each other books.

The banks dont pay depositors they give them nothing then loan out the money and keep all the interest. You keep money in the bank because it is easier to pay bills. If you want to get paid interest you go to a hard money lender they pay you most of the interest paid by the borrower and take .5% leaving you with 8.75% and collateral if the loan fails.

I sat the test, and got question 5 wrong. I don't understand why I did. The question basically says, companies A B C want to borrow money. If their interested is capped below a certain rate, then the company will be success. A and C have the rate below the specified amount, so I picked them two as the companies/projects banks would invest it, because they'd be more likely to get their money + interest back. However, B was the right answer, and their interest rate would have made them not 'successful' If anyone could explain I would be most appreciative!

How much agreement is there among mainstream economists on this "Financial Intermediary" view of banking? Some vocal critics of the banking industry insist that banks do NOT lend borrowed money, instead they create loans out of thin air by merely making a bookkeeping entry. Ordinarily I would dismiss a claim like this as silly but some notable economists and central bankers have made the same claim that an individual bank creates a loan ex nihilo.

I'm not an economist, so I can't be sure, but as far as I can see the idea of these "ex nihilo loans" must be false. And this is because of the principle of the tragedy of the commons. If banks could make loans out of thin air, that is the equivalent of them printing money themselves. And so there is no reason not to make as many of these ex nihilo loans as possible, because if they do they get free profit, and if they don't other banks will push them out of business by offering this type of loans. So every bank would do this resulting in endless hyper inflation everywhere. So if my logic is reasonable, this concept is impossible. I also would love an answer video MRU! Is there any reality behind this claim, or is it indeed patently false?

I'm far from an economist either, but I'll give it a crack. I think it IS true, basically because we have socialist banking in the form of the Federal Reserve. It may sound insane, but so do all other socialist schemes. Banks get to make loans of money that they don't have because the socialist government keeps printing insane amounts of money out of thin air. They also add staggering amounts of debt every year. The national debt has gone up by crazy amounts every year at least since the mid-'90s. This money is given to the banks. So, banks can essentially loan out money that they don't have and doesn't exist because of the (sadly rightful) anticipation that the money will be there the next year. The government creates it out of thin air in the form of debt and printing. It's not real banking based on a real, limited currency. That is my stab at it, I'm not sure if it's true.

RonaldReaganRocks1 So basically you're saying that it does happen it's just the central banks that do it rather than the private ones? I could see that because they have control over their respective currencies, and it would take care of the tragedy of the commons problem. But when I see this claim it's usually based around it being all banks, which still doesn't make sense.

All banks create money through double-entry accounting. They give a +$100 to you to spend (the money) as well as a -$100 to you to pay back (the loan). It looks the same on their books, except reversed. The amount that they give you is -$100, and the loan is counted as +$100. By making a loan they are temporarily creating money that is destroyed when the loan is repaid. They make the interest as profit. The misconception is that they are loaning free money. The money isn't free for the bank because the loan also includes a negative entry in their books that must be paid. Theoretically, they could loan out an infinite amount of money. But, it doesn't work that way for two reasons. First, their is a fractional reserve limit. This says that, if you have $100 in "reserves", you can "create" $1000 in loans for a fractional reserve limit of 10%. Second, a bank must manage the risk that a loan isn't paid. If too many loans aren't paid, a bank could go into the red. In this example, a bank owes $1000 because it loaned that much out. But, it now has $1100 of reserves. But, $1000 of those reserves are the loan which will be paid off over time. It is an asset, like a bond. If the loan is defaulted on, those reserves don't exist anymore. In that case, the bank still owes the $1000 that were loaned while only having $100 in reserves. I'm simplifying this by neglecting interest and saying that a payment was never made on the loan, but I hope that you get the idea.

i guess this is a basic explanation about Banking since real Banking is much more complicated to Depositors and clear to bankers. Banks generate virtual money out of thin air due to Money Multiplier which does no show in Balance Sheets and does not distribute dividends to depositors. any creditor is considered a new depositor therefore REquired and Excess REserves are applied whereby the loan is strictly out of the unreserved amount of deposits whilst the virtual money is transformed to Treasury and transformed into assets to Bank's private profits. Lehman Brothers Bank is the best example of such a dilemma. it was bankrupted and Board members were receiving Bonuses. Banks' employees are fascinated with commissions therefore they would do anything to find new depositors and most Creditors. Dear Marginal REvolution University can you please explain again the same with the Money Multiplier factor? thank you and appreciate your efforts.

What do you think limits this creating of new money? It has the amount of money in circulation from the fed (base money supply). Only banks that get a lot of depositors can then create this money out of thin air but if they had no deposits they can create NO money lol. Otherwise we would have immediate hyper inflation and interest rates of 0% due to an infinite money supply by every bank making endless amounts of money. Research fractional reserve

@@kingal89 Sorry, buddy, but you're incorrect. Dont read up on all the misinformation on fractional reserve banking... I recommend the very good paper from the Bank of England or a paper from McKinsey (titled: *Repeat after me: Banks Cannot And Do Not "Lend Out" Reserves* ). Learn the basics of accounting and balance sheets and you'll understand that the loanable funds theory is complete bogus. Yes, there are limitations to commercial banks' credit-provision, but they have nothing to do with some magical funds limits rather than with profitability at the operative level. The causality of money creation is opposite to the money multiplier fairy tale. Banks give credit beforehand according to solvency of the borrower and the bank's business interests and then afterwards they refinance if necessary. The minimum requirements are checked in period intervals in between banks are not constantly monitored. That alone reverses causality, because Central banks dont set the money base, they specify interest rates according to which banks can refinance... And there are other ways to get reserves, e.g. selling assets to the central bank, or using inter-bank-lending. If the Fed or any other central bank for that matter ever said "no" to a commercial bank asking for reserves, then maybe at least the central bank would act as a limiting authority. But that never happens. It would remove a lot of flexibility in credit processes. If banks had to get reserves first, before they give credit to borrowers, that would complicate things quite a lot... But even if that was the reality on the ground (as opposed to ivory tower text book fairy tales), the loanable funds theory is in direct violation of basic accounting principles. A bank is not a fiduciary taking care of their customer's money... That would be the case in a souvereign / positive money system, but not with the current general accounting principles. Banks simply cannot lend out any reserves, that's logically incompatible with how balance sheets work. And that's irrespective of whether or not a central bank could theoretically limit M1 by denying any further business with commercial banks or setting interest rates so high that it would not be profitable for commercial banks to borrow from the CB. (which might not be in their interest to stifle the economy) And on top of that... Borrowing from the CB is not the only way to increase the money base... Banks can sell assets to the CB which then credits new reserves in the bank's deposit. And there is no limit on financial assets to be created, since they are merely claims on means of payment (or claims on claims, aka derivatives). Private institutions could create a lot of toxic shit and then the CB or Fed buys these assets off of them and thereby increases the money base. In theory, the CB could say No and strangle the economy... But that never happens, they play ball... Sorry, buddy, but you're incorrect.

Everyone saying this isn't how banks work has no idea how banks work. Banks base how much money they can "create" out of how much they have access to in deposits. Look up fractional reserve. Most of our money is created out of thin air by banks but it is based on the amount of base currency produced by the Fed and the fractional reserve limit set at the bank. The system is HIGHLY leveraged and will come crashing down eventually. The US dollar is tied to nothing in value. It used to be tied to gold then it became debased and was still tied to gold but not in 1:1 amounts. Then they completely came off the gold standard when the world realized American was conning the system by having the USD be the reserve currency tied to gold and all other currencies being tied to the USD. This pissed off countries such as France and they basically made a run on the american gold vaults forcing America to go off the gold standard. Now our government prints as much as it wants and banks literally create money out of thin air but it is still based on the base currency in circulation and set reserve limits. So this idea of deposits isn't wrong but isn't the full picture.

The United States became the powerhouse that it is because it produced and exported much of the non-war goods during the world wars and was paid in gold. At one point we had most of the gold in circulation in our vaults. It all fell apart when we started printing excess money at the expense of other countries who had currencies tied to ours. It was wrong and basically fraudulent. Most people have no idea how worthless every single currency is in circulation around the world. They are all tied to absolutely nothing. If you want to save up for the future this is why it is so important to invest in assets. Things with real "value". Never save your money in cash because you are holding onto something that is worthless as soon as the bigger fool theory no longer works (possibly during next global depression).
