What is money?
People are used to the saying that money makes the world go round. But what does this mean? We use different forms of money every day: to buy something in the supermarket or coffee shop, to pay our bills, or by adding to our savings accounts. Money can take different forms and shapes. This includes coins and banknotes, but also electronic bank drafts and credit cards or even mobile phone credit.
People can keep money in their wallets, hoard it under their mattresses or put it in their bank vaults, unlike a kilo of apples, money doesn’t spoil
Money is used as a medium of exchange. Rather than exchanging lets say a kilo of apples for a book, most people use money in sale and purchase transactions. Money also serves as a unit of account. People and countries use money to measure the value of goods and services and to account for debts. A third function of money is that of a store of value. People can keep money in their wallets, hoard money under their mattresses or put it in their bank vaults and retrieve it at a later stage. Unlike the kilo of apples, money does not spoil.
Value and Prices
Trust is an important element of money – we have to trust that our money will be accepted in transactions and that it will retain its value if we put it in our bank account. Often, states use monetary policy to control the supply of money in the economy. This is to prevent prices from rising too fast and achieve stable price levels. If money uses its value too rapidly, this might lead to inflation. People lose confidence in their money and struggle to afford basic goods, such as food stuffs. However, if the money supply is too low the economy can be starved of funds. People might find it difficult to transact, salaries decline and people might again find it difficult to afford basic expenses. It can lead to austerity and depression. Does money have value of its own? Commodity money such as gold coins certainly does. However, nowadays most economies are dominated by so-called fiat money in the form of paper money or even electronic drafts. Here, it is the purchasing power that is thought to constitute the value of this money.
“Money is a claim upon society”
Speculation and Governance
States and money intersect in many ways. Sovereigns seek to control who can issue money. They also define what is to be accepted as legal tender. States also seek to maintain the value of national currencies. If currency values depreciate rapidly, this can result in a currency crisis, as happened for example in East Asia in the late 1990s. International speculators took a stand against Asian currencies and governments were no longer able to retain their values. As the value of East Asian currencies fell, borrowers who had raised loans in foreign currency were caught out as suddenly these loans had become much more expensive. Students studying abroad on government scholarships were also caught unawares as their maintenance grants unexpectedly were worth much less. Policymakers in the 1940s had diagnosed the harm that could be caused by volatile international capital flows. In 1944 they had agreed a system to regulate international capital flows – the famous Bretton Woods system. However, this system unravelled in the 1970s and the repercussions of this could be felt during the Asian financial crisis, which was only one of many.
Sociality of Money
Money does not only have economic functions, it also has important social and cultural functions. For example, the economic sociologist Vivien Zelizer has studied how people relate to money and develop various ways to engage it. Indeed, money can be used for purely ceremonial purposes with no market value whatsoever as ancient coin hoards seem to demonstrate. Often, money is linked to status. In many cultures, money is exchanged as gift for special occasions. Money plays an important role in many religious rites and ceremonies – take for example the burning of spirit money to worship ancestors which is a common Chinese tradition.
