We’re used to thinking of money as notes and coins, the kind most of us hold in our wallets. But most money – in Australia it’s 96.3% – is digital, held by financial institutions and moved around via bank transfers, debit cards and credit cards.
Late last year, Treasurer Josh Frydenberg promised to consult about introducing a third type of currency, a central bank digital currency, and asked the treasury to come up with a position by the end of 2022.
A central bank digital currency (CBDC) would be an “e-dollar”, each one worth $1 dollar, but able to be held digitally without being put into a bank – such as on computers or in digital wallets on phones.
It could allow direct consumer-to-consumer and consumer-to-business payments without the intervention of financial institutions, and allow people who don’t want to use banks to hold funds in a form that’s safer than cash.
It could also head off attempts by private firms – such as Facebook, which proposed something called Libra – to do the same sort of thing.
For transactions, it would have a clear advantage over so-called cryptocurrencies such as Bitcoin, whose values fluctuate because they’re not tied to a currency.
Many central banks are investigating the idea, but most say they’re unlikely to issue a retail CBDC in the foreseeable future.
Australia’s Reserve Bank is particularly unenthusiastic, declaring there is “currently no strong public policy case to introduce a CBDC for retail use”.
Whereas in much of the rest of the world the use of cash is shrinking, in Australia there are more banknotes in circulation as a proportion of the economy than at any time since the introduction of decimal currency in 1966.
Most of the cash appears to be used to store money rather than execute transactions. But if ever Australians could be weaned off cash, there would be savings for the Reserve Bank in the cost of printing and distributing cash, and also, most likely, fewer robberies.
But how the idea would work isn’t clear.
