Many countries are going cashless at great speed. What are the advantages of ditching hard cash and what are the dangers? Read more about a cashless future here: https://econ.st/2Mwhipb Click here to subscribe to The Economist on YouTube: https://econ.st/2xvTKdy Somewhere in the near future physical money will become like these - Relics of a different age. And will only be found in places like this. In other words hard cash will disappear. It will become electronic - transferred by things like these. So what’s the rush to get rid of cash? And what’s the cost? Let’s face it money is cumbersome for consumers and banks. Operating in cash costs countries about 0.5% of their GDP every year. But cost isn’t the only incentive to move towards a cashless future. Digital payments aren’t just easy - they are neat. Having every single payment automatically recorded is efficient. But there’s a downside. Electronic-money trails can allow governments and private companies to access and harvest personal data. But there’s another threat that is worrying banks - cyber-attacks. Still many countries are fast moving towards a cashless society. In Sweden the number of retail cash transactions per person has fallen by 80% in the past ten years. The trend is even evident in far more cash-loyal societies. China’s digital payments rose from 4% of all payments in 2012 to 34% in 2017. The trend is inevitable but a gradual transition is key. Some people may find it harder to grasp how much money they have without the physical representation of it. Not everyone knows how to use internet-banking technology. And people living in remote areas where internet cover is patchy may find they have to drive for miles for their basic needs. And there is another sector of society that relies heavily on cash. Going cashless is just the latest evolution of money in the modern economy. But it raises a fundamental question - what is the value of money if it doesn’t physically exist? The move towards cashless societies is well under way. But governments need to ensure that, as cash is phased out, the vulnerable in society aren’t left behind. They need to navigate carefully the many pitfalls that a digital economy will bring.
