Let us consider a
loan bank, also called a savings-and-loan bank or savings-and-investment
bank. This is where a bank loans out
saved funds to borrowers.
Suppose a wealthy merchant has a large stock of gold,
held safely in his own personal storage safe.
He does not want to use the gold for his present consumption; he wants
to use it for future consumption or to leave for his children after he is
gone. He has no plans to use the money any
time soon. His gold lays dormant in his
safe.
One day, he meets a poor salesman who has a great
idea for a business venture. The
salesman is certain that if he had 10oz of gold, he could make such a
successful business that he will have 20oz in a year’s time. But the salesman does not have 10oz; he
spends virtually all of his meager income on consumption, and has no
savings.
The wealthy merchant, convinced by the soundness of
the salesman’s plan, and his ability to pull it off, agrees to lend him 10oz of
gold on the condition that he pay back 11oz of gold in one year’s time. The salesman readily accepts, confident that
his business idea will work as he predicts, and he will have 9oz profit after
he has paid back his loan. The merchant
will earn 1oz of income for doing nothing, except for giving up 10oz of gold
for a year, and choosing someone he considers a good investment.
Note the very important social role of the merchant
here. He is a man with no ideas about
how to change the productive structure of society; he has only his saved
money. Meanwhile, the salesman has a
great idea, and needs only the start-up money in order to improve the
productive structure. The merchant’s
prior savings make the improvement to the productive structure possible. The premium (1oz) that merchant earns is his
payment for waiting for future goods rather than consuming present goods. Hence, the rate for renting money, the
interest rate (here, 10%), will be determined by the lenders’
time-preferences.
It is clear that both parties will benefit from this
loan agreement and society as a whole will also benefit through increased
productivity.
The salesman’s business idea may or may not have
worked. It is in the interest of both
men for the venture to be successful. If
it failed, and the salesman was not able to pay back his loan, the loss is
suffered by the merchant. If a contract
agreement was made (i.e. a transfer of property rights) then this is considered
implicit theft by the salesman from the merchant. The merchant has a right to his money
back. If the contract included
collateral (an asset like a house) then the merchant has a right to ownership
of the collateral. Often however, there
may be no collateral or it may not fully recompense the lender, in which case
the lender must suffer the loss.
Whatever the case, there is a strong incentive for lenders to wisely
choose who they lend to. Competition
ensures that only those lenders who choose wisely will stay in business.
Note that clearly the merchant cannot use his 10oz
for any of the year of the loan. This is
because the salesman has spent it. It was
after all a loan, not a bailment, not a demand deposit. The merchant’s money is not available on
demand, so for the year, it cannot be said to be his money. The money supply here has obviously not been
increased. The gold in the merchant’s
safe was handed over to the salesman and at that moment it became his property,
to do with as he will.
If the salesman’s business succeeded, and at the end
of the year he had indeed turned 10oz of gold into 20oz as he predicted, he
hands 11oz is handed back to the merchant.
Where the salesman gained 9oz and the merchant 1oz, the customers that
bought from the new business gave up 10oz, and there is no net change in total
supply. If the business failed entirely,
and the salesman lost the whole 10oz, then the merchant has simply lost 10oz
and some other individuals have gained 10oz.
Again, no change in the total money supply.
Let us suppose that the salesman’s business venture
worked. The merchant, pleased with how
he was able to make a profit merely from lending his own money, decides to find
other entrepreneurs with great ideas. He
becomes an investment banker,
providing a vital service for society.
He invests in several entrepreneurs, whom he has faith in. He adds a premium for the risk that he is taking, the possibility
that some ventures may fail and he will suffer the loss.
After investing in several entrepreneurs, the
merchant-banker finds that his personal gold stock is getting low. But there are many entrepreneurs out there
with good ideas, and the merchant-banker wants to lend to them. And so the merchant-banker will go to his
wealthy friend, a doctor, who has a large personal stock of gold, and get his
own loan from him. The doctor lends the
merchant 100oz (not a bailment), in exchange for the promise to pay back 102oz
in a year’s time (2% interest). With the
100oz from the doctor, the merchant-banker lends it out to eager entrepreneurs
on the condition they pay back at 6% interest.
The merchant-banker will pay 2% to the doctor as agreed, and keep the 4%
as profit.
Note here the important social function played by the
doctor. Like the merchant in the
previous case, it is the doctors’ savings that make the new businesses
possible, and his profits (a virtually guaranteed rate of return) are payment
for foregoing present goods and instead waiting. Unlike the merchant, though, the doctor does
not need to know the entrepreneurs or even what they are doing. This is the business of the merchant-banker. The doctor is bearing almost no risk, because
he is not trusting any single entrepreneur (like the merchant did with the
salesman), but must only trust that the merchant-banker will not go bankrupt and
will be able to pay him back.
