The velocity of money (or the velocity of circulation of money) is a measure of the number of times that the average unit of currency is used to purchase goods and services within a given time period.[3] The concept relates the size of economic activity to a given money supply, and the speed of money exchange is one of the variables that determine inflation. The measure of the velocity of money is usually the ratio of the gross national product (GNP) to a country's money supply.
If the velocity of money is increasing, then transactions are occurring between individuals more frequently.​[3] The velocity of money changes over time and is influenced by a variety of factors.[4]

Illustration​[​edit​]
If, for example, in a very small economy, a farmer and a mechanic​, with just $50 between them, buy new goods and services from each other in just three transactions over the course of a year
then $100 changed hands in the course of a year, even though there is only $50 in this little economy. That $100 level is possible because each dollar was spent on new goods and services an average of twice a year, which is to say that the velocity was
. Note that if the farmer bought a used tractor from the mechanic or made a gift to the mechanic, it would not go into the numerator of velocity because that transaction would not be part of this tiny economy's gross domestic product (GDP).
Relation to money demand​[​edit​]
The velocity of money provides another perspective on money demand. Given the nominal flow of transactions using money, if the interest rate on alternative financial assets is high, people will not want to hold much money relative to the quantity of their transactions—they try to exchange it fast for goods or other financial assets, and money is said to "burn a hole in their pocket" and velocity is high. This situation is precisely one of money demand being low. Conversely, with a low opportunity cost velocity is low and money demand is high. Both situations contribute to the time-varying nature of the money demand.​[5] In money market equilibrium​, some economic variables (interest rates, income, or the price level) have adjusted to equate money demand and money supply.​[​citation needed]
The quantitative relation between velocity and money demand is given by Velocity = Nominal Transactions (however defined) divided by Nominal Money Demand.
Indirect measurement​[​edit​]
In practice, attempts to measure the velocity of money are usually indirect. The transactions velocity can be computed as
where
is the velocity of money for all transactions in a given time frame;
is the price level;
is the aggregate real value of transactions in a given time frame; and
is the total nominal amount of money in circulation on average in the economy (see “Money supply” for details).
Thus
is the total nominal amount of transactions per period.
Values of
and
permit calculation of
.
Similarly, the income velocity of money may be written as
where
is the velocity for transactions counting towards national or domestic product; and
is nominal national or domestic product.
Determination​[​edit​]
The determinants and consequent stability of the velocity of money are a subject of controversy across and within schools of economic thought. Those favoring a quantity theory of money have tended to believe that, in the absence of inflationary or deflationary expectations, velocity will be technologically determined and stable, and that such expectations will not generally arise without a signal that overall prices have changed or will change.
Criticism​[​edit​]
Ludwig von Mises in a 1968 letter to Henry Hazlitt said: "The main deficiency of the velocity of circulation concept is that it does not start from the actions of individuals but looks at the problem from the angle of the whole economic system. This concept in itself is a vicious mode of approaching the problem of prices and purchasing power. It is assumed that, other things being equal, prices must change in proportion to the changes occurring in the total supply of money available. This is not true."[6]
