Money creation

Money creation is the process by which money is produced or issued. There are two different ways to create money:

physically manufacturing a new monetary unit, such as paper currency or metal coins
loaning out a physical monetary unit multiple times through fractional-reserve lending

Coins are produced by manufacturing metal in a factory called a mint.

Banknotes and bank account balances are financial securities issued by a bank.

Similarly, money destruction, i.e., the reverse of money creation, can occur in two different ways, depending on how the money was created. The destruction of physically created money occurs when coins are scrapped to recover their precious metal content, or when the issuer redeems the securities. The destruction of money created through loans occurs as the loans are paid back.

The practices and regulation of production, issue and redemption of money is of central concern to monetary economics, and affect the operation of financial markets and the purchasing power of money.

Money creation by mints

Under competitive minting

Competitive minting means that the business of manufacturing coins is open to many competing manufacturers. The mints buy bullion on the bullion market, and manufacture it into coins that they use to pay for the bullion and their other production costs, and to provide a profit.

Analysis of supply and demand cannot proceed in the normal way because by definition, the money price of money is fixed at unity. Instead, metal producers need money to pay their expenses and to realise their profits in money, and so their demand for money is expressed by their willingness to produce and sell uncoined metal at a discount to its value as coin. This discount is the gross profit margin of manufacturing metal into coin, and the greater this is, the more metal the mints will find economical to manufacture into coin.

Under nationalized minting with a right to exchange

Nationalized minting means that the government has monopolised the business of minting coins, and the government operates mints that produce a national system of coinage. Under a metallic or bimetallic standard with a national mint, individuals normally have a right to bring precious metal to the national mint and to have it coined at a fixed discount. This discount is called seigniorage.

Basic economic analysis of this arrangement is that it makes the supply of coin elastic at the fixed price, however this fixed price is effectively a price control, and price control theory implies that the supply of coin would be more elastic (responsive) under competitive supply and no price controls.

Under nationalized minting with no right to exchange

Where there is no legal right to take metal to the national mint and to have it coined into a particular coin, the supply of the coin depends on government or mint policy. This can result in arbitrary debasement of coinage, where the government mint re-manufactures coin with a lower metallic value as a way to raise revenue. However it also enables some more complex coinage arrangements such as the composite legal tender system where gold coin was unlimited legal tender (produced under a right of exchange arrangement as above) and where silver coins are limited legal tender, and have a substantially reduced metallic value below their legal value, but are effectively redeemable at the mint for their legal value in gold coins. This makes the silver coins 'token' coins, and a form of financial asset (and a financial liability to the mint). central bank does not transact business with private individual they are the banker's bank, they act as agent of the government. 1. they issue currency to the public 2. they are establish by parliament 3. their main aim of establishment is not profit making 4. they do give advice to the government 5. they don't accept deposits from individuals 6. they don't transact business with private individuals

Money creation through the fractional reserve system

Fractional-reserve banking creates money whenever a new loan is created. In short, there are two types of money in a fractional-reserve banking system^[1]^[2]:

central bank money (physical currency)
commercial bank money (money created through loans) - sometimes referred to as checkbook money^[3]

When a loan is supplied with central bank money, new commercial bank money is created. As a loan is paid back, the commercial bank money disappears from existence. The table below displays how central bank money is used to produce commercial bank money.

			total reserves:

	commercial bank money created + central bank money:	commercial bank money created:	central bank money:
	457.05	357.05	100

Although no new money was physically created in addition to the initial $100 deposit, new commercial bank money is created through loans. The 2 boxes marked in red show the location of the original $100 deposit throughout the entire process. The total reserves plus the last deposit (or last loan, whichever is last) will always equal the original amount, which in this case is $100. As this process continues, more commercial bank money is created. For more information on how this system works, see Fractional-reserve banking.

Money multiplier

The most common mechanism used to measure this increase in the money supply is typically called the money multiplier. It calculates the maximum amount of money that an initial deposit can be expanded to with a given reserve ratio.

Formula

The money multiplier, m, is the inverse of the reserve requirement, R^[7]:

m={\frac {1}{R}}

Example

For example, with the reserve ratio of 20 percent, this reserve ratio, R, can also be expressed as a fraction:

R={\tfrac {1}{5}}

So then the money multiplier, m, will be calculated as:

m=1/{\tfrac {1}{5}}=5

This number is multiplied by the ~~initial deposit~~ excess reserves to show the maximum amount of money it can be expanded to^[8].
