Cash is no longer King: the future of a cashless society

Sweden is on track to becoming the world’s first cashless society in 2023. About 80% of Swedes use a debit or credit card to make purchases (Sweden.se, 2019). A cashless society can be defined as the absence of physical cash such as notes and coins, whilst digital payments gain the upper hand (Dictionary.com, 2019). One factor that certainly is relevant, is the population of Sweden. With an estimated population of 10,040,995 in 2018 (CIA World Factbook, 2018), one may argue that it is easier for Sweden to become cashless than other countries with significantly larger populations. Nevertheless, the impact that a full cashless society has is considerable.

Aside from the intuitive factors that a cashless society is considered more convenient and transparent, but also more prone to hacking, there are other relevant factors.

The Boston Consulting Group (2019) estimates that a cashless society would increase annual GDPs of developing economies by 3 percentage points and developed economies by 1 percentage point. This is due to the increased velocity of transactions and the increased transparency (BCG, 2019).

Theoretically, a cashless society would also have a positive impact on the government, through increased tax surveillance (Berentsen and Schaer, 2016). Transactions via transfers are more easily traceable and executing cash-in-hand-jobs becomes more difficult. Ideally, this would have positive spill over effects of higher tax returns and reduced national debt and more financially stable economies (Berentsen and Schaer, 2016). This does not account for market imperfections though. Illegal activity, such as tax evasion, will most likely continue, as alternative forms of payment emerge, either reversing back to payments in the form of commodities like gold or through cryptocurrencies and offshore accounts (Berentsen and Schaer, 2016).

Additionally, cash is the only barrier to the elimination of the zero-lower bound of nominal interest rates (Buiter, 2016). As soon as people need to pay for keeping their money on a savings account, it will be cheaper for people to withdraw it all and store it elsewhere in cash. This makes it ineffective to have negative interest rates, without a prior ban of cash (BCG, 2019).

Considering that the Netherlands has also limited the locations where you can pay with cash, do you believe the outlook on a cashless society is positive or negative?

Turning on your light using the neighbour’s energy…

That sounds illegal at first, right? But this may soon become the future!

Blockchain is one of the buzzwords of the century, but could be the solution to peer-to-peer energy trading. The idea of this is, that my neighbour and I both produce our own energy due to e.g. solar panels on our roof. Meanwhile, the “Smart Energy Meter” in my cellar compares my production and consumption of electricity. If I now require more electricity than I produce, I have the opportunity to buy this from other solar panel owners with an excess supply in my neighbourhood via a blockchain (Next Kraftwerke, 2019). In this case everyone becomes a “prosumer” (consumer and producer combined). The blockchain allows two or more parties to make transactions with one another, without the presence of an intermediary such as a bank or trader and an increased focus on security (dena, 2019).

Ultimately, everyone would be able to buy and sell their own energy, based on their individual production and consumption. The image above (Woerner et al., 2019) illustrates this quite clearly. The left side of the image shows the traditional supply of energy through the utility, and the image on the right shows how this is decentralised by the blockchain. The next step is that I can even sell back my excess energy supply to the utility company as an alternative to selling to my neighbour, in the blockchain-based system.

The city Wuppertal in Germany was the first in Europe to sell renewable energy via a blockchain. In the image above you can still see the utility companies or energy providers who supply their share into the energy grid. Yet, over time the blockchain technology decentralises the energy industry, which leads to lower energy costs, as stock / commodity markets are skipped. In the long-term this could lead to the elimination of energy providers, leaving only the prosumers in the market.

As interesting as this may sound, a barrier to implementation is the increased effort for consumers associated with this model. Energy providers must develop their own platforms to facilitate peer-to-peer trading. Otherwise, this will result in the lack of adoption due to increased complexity and lack of motivation amongst the general population.

Overall, would you become a prosumer?
