Central Banks’ Blockchain Solutions for Financial Inclusion

All these pilots and early experimentations with blockchain solutions are thought to face the multiple challenges that many times, unfortunately, central banks can’t address. Most notably: Emergent Economies.

The application of DLT and blockchain in emerging economies of developing countries is of great interest to the central banks. In these locations, like in most of Africa, some countries of South America and part of Asia, central banks face greater challenges than their Western counterparts: their populations are mostly unbanked with very limited access to private banking; payments systems work between private financial institutions with little or non-existent communication to Central Banks while most of these payments are done through printed money rather than through electronic solutions. All of these make the role of the Central Banks pretty much inefficient. They can’t control how much money flow is happening between hands, they can’t authorize private banks payments, loans and other services and they can’t effectively control money laundering and other submerged economy that may flourish.

Cambodia is a country that is trying really hard to tackle the unbanked population through blockchain solutions. Most of the people in this country make their payments in cash or mobile-based private applications. They struggle to keep their savings in safe financial banks while they also have difficulties transferring money to those who use a different mobile money application.

“The National Bank of Cambodia will be one of the first countries to use blockchain technology in its national payments systems for use by consumers and commercial banks. It is implementing blockchain technology in the second half of 2019 as an experiment to support both financial inclusion and greater banking system efficiency,” mentioned in the aforementioned WEF report.

Central Banks and Digital Currencies

The solutions that central banks are experimenting with vary from one to another. Some focus on developing a national blockchain platform connected to private financial institutions to allow for better communications between them. This would help to authorize and permit legitimate transactions among clients, banks and the central bank. Others try to make their already functioning systems more efficient and fast. And other solutions are a bit more courageous: a blockchain platform thought and deployed to print digital currency that could be equivalent to – and redeemable for – its domestic currency. This method is what is called Central Bank Digital Currency or CBDC.

“Central Bank Digital Currency (CBDC), a commonly proposed application of blockchain and distributed ledger technology (DLT), has attracted much interest within the central banking community for its potential to address long-standing challenges such as financial inclusion, payments efficiency, and payment system operational and cyber resilience. Including but not limited to CBDC, central banks are researching and experimenting with at least 10 specific use cases for blockchain and DLT, exploring where they can potentially unlock new possibilities and improve inefficient processes,” said Ashley Lannquist, Project Lead, Blockchain and Distributed Ledger Technology, World Economic Forum.

Central Banks already issue money electronically, but CBDC, by contrast, is typically issued on distributed ledgers – or blockchain platforms – where it can be transacted in a peer-to-peer manner, facilitating more rapid or cost-efficient transactions in some contexts. CBDC could bring important benefits to a country’s financial system health, including the potential for faster and cheaper domestic and cross-border payments; the improvement of payment system resilience to cyberattacks, operational failures and hardware faults relative to centralized data storage and processing, which has less data redundancy and, therefore, may be less robust or even fostering AML/KYC functionalities and to reduce tax evasion, corruption and illicit activities. A digital currency on a distributed ledger could potentially challenge commercial banks current monopoly, allowing a tighter pressure on commercial banks to increase interest rates to depositors and provide more financial services.

For now, however, these are only experiments and theory but the trend goes towards the adoption of blockchain in central banks. What was seen a few years back as a threat by the IMF and the World Bank, now it has become the latest saviour of a financial system deeply wounded. “Over the next four years, we should expect to see many central banks decide whether they will use blockchain and distributed ledger technologies to improve their processes and economic welfare. Given the systemic importance of central bank processes, and the relative immaturity of blockchain technology, the banks must carefully consider all known and unknown risks to implementation,” concluded the World Economic Forum report.

What is mandatory in the dawn of the Fourth Industrial Revolution is the need of an upgrade – and update – of our current financial services industry. This swift move to the digital must be done in coordination with governments and central banks to keep new and emerging technologies, such blockchain, on the right path. Some Central Banks are speeding up their research, though there is still much left to do. We are still years away to see feasible proposals and, even longer, to deploy them.
