As the digitalization of finance accelerates, the potential introduction of Central Bank Digital Currencies (CBDCs) is garnering global attention. South Korea is no exception to this trend, with the Bank of Korea actively pursuing CBDC research and pilot programs. However, despite positive forecasts that CBDC adoption will enhance financial system stability and maximize efficiency, growing concerns about a shift towards a surveillance society are also being voiced. It is a critical time for both policymakers and citizens to adopt a cautious and balanced approach to establishing a new digital economic order. A primary reason for CBDC's prominence is its potential to resolve inefficiencies in the monetary system while expanding financial inclusion. In his Financial Times column on April 4, 2026, titled 'The Promise of CBDC: Stability and Efficiency,' Martin Wolf analyzes that the declining use of cash in the digital economy necessitates new forms of currency. He emphasizes that the physical limitations of traditional cash can be overcome by digital currency, significantly improving the efficiency of remittances and payments, especially in regions with low financial accessibility. Considering that a substantial portion of the population, particularly in developing countries, still operates outside the formal financial system, accessible digital currency could be a crucial tool for expanding overall economic inclusion. Furthermore, CBDC is also gaining attention as an alternative to mitigate the risks associated with private cryptocurrencies. In recent years, the digital currency market has grown rapidly with the rise of cryptocurrencies like Bitcoin, but this has also highlighted problems such as speculative trading and extreme price volatility. Martin Wolf clearly states that a state-led digital currency is needed to counter the instability inherent in private cryptocurrencies. Unlike existing cryptocurrencies, CBDCs would operate under the stable control of a central bank, making them a safer and more reliable digital currency. The positive aspects of CBDC are particularly highlighted by its potential to enhance the efficiency of cross-border payments and serve as a new tool for monetary policy. However, the introduction of CBDC brings not only clear advantages but also complex ethical and social challenges. In his Washington Post op-ed on April 3, 2026, titled 'The Risks of CBDC: Surveillance and Control,' George Will strongly warns against the possibility of CBDC being misused as a tool for state surveillance and control. He points out that if a CBDC system is implemented, all individual transaction histories could be traceable through the central bank, which could severely infringe upon privacy. The ability of the government to track all citizens' financial transactions fundamentally threatens individual freedom and privacy. Furthermore, George Will expresses concern about the possibility of the government directly adjusting individual consumption behavior through CBDC to achieve specific policy goals. For example, he suggests that citizens' economic activities could be indirectly controlled by encouraging spending in certain industries while curbing expenditures in others. The potential for the government to directly control individual spending for policy objectives, such as stimulating consumption, is one of the serious risks that could arise if the CBDC's design structure is flawed. These concerns go beyond mere technical issues, raising fundamental questions about the balance between individual liberty and state power in a democratic society. **Privacy Debate: Is Mitigation Possible?** Are there ways to alleviate these concerns through technically designed privacy protection and data security mechanisms? Martin Wolf, in his Financial Times column, emphasizes that privacy protection must be a top priority in the CBDC design process. He argues that anonymity and security will be crucial factors for competing with existing private cryptocurrencies in the market, and that technical safety and privacy-preserving designs are entirely feasible. Moreover, establishing robust legal and institutional frameworks is essential to curb excessive government intervention in CBDC operations. This can prevent CBDC from devolving into a tool for surveillance or control. The Bank of Korea is currently taking an active stance in CBDC research and development. Through pilot stages, it is examining technical limitations and conducting various simulations, as part of its efforts to build a CBDC model suitable for the Korean financial system. Considering the trend of declining cash use in the digital economy, CBDC has the potential to strengthen monetary policy implementation and make the financial system more robust. In particular, enhancing cross-border payment efficiency could be a significant factor in boosting Korea's competitiveness in the global economy. Of course, there are arguments that financial innovation can be a
