Come back in time with us to discover why currency was invented

Swap: a sheep for a barrel of wheat

Why was currency needed?

Around 9000 years B.C. Stone Age people discovered farming and began to trade. They found that by keeping cattle in pens and growing crops, they could produce more food than they could eat. What's more, they could ‘sell’ the food they didn't need in order to ‘buy’ other things. For example, if they had a cow and needed wheat, they would exchange the cow for wheat. In the same way, if they had wheat and needed a cow, they would make an exchange.

 

This first system of exchange – ‘buying and selling’ – was called bartering. Although it was used for thousands of years, it wasn’t ideal. If you have ever swapped something you probably have a good idea of some of the possible problems. The idea of currency – that objects like stones could be used to represent value – came about as a way to solve the problems of bartering.

What were the problems of bartering?

  1. You needed to find someone who wanted what you had and had what you wanted.
  2. You had to find a way of making up the differences in amounts. If the two things didn't have the same value, it wasn't easy to divide them.
  3. Many 'goods' grew old or rotted and didn't keep their value.
  4. They weren't easy to carry.
  5. It was difficult to compare the price of a good against all other goods. The possibilities were endless…
“I think 1 cow is worth 5 chickens or 2 horses.” – “No way, I bought 6 chickens for a cow the other day.” – “I haven't got a clue what sheep are worth compared to chickens!”

So a general measure was needed to be able to compare the value of these goods more easily. This is where currency comes in.
