Part 3. Borderless Money, Bordered Sovereignty: The Battlefield of the Digital Currency Cold War 🌐
The discussion around stablecoins extends beyond technical architecture into geopolitical dimensions. As stablecoins pegged to the US dollar become the lifeblood of the global digital financial ecosystem, they are evolving from a mere market phenomenon into a powerful tool for extending US monetary hegemony into the digital realm.
The Shadow of Digital Dollarization: The Neutralization of National Economies
Digital dollarization refers to the widespread adoption of digital dollars like USDC or USDT by economic actors within a nation as a means for everyday transactions, savings, and investments, replacing their national currency. This phenomenon can spread rapidly, especially in countries with unstable local currencies, but it is also quietly infiltrating developed economies. For instance, if a developer in Seoul receives payment from a US client in USDC and deposits it into a Decentralized Finance (DeFi) protocol without converting it to Korean Won, earning dollar-based interest, those funds bypass the Korean financial system entirely. 
As this trend deepens, nations face severe threats to their sovereignty:
- Neutralization of Monetary Policy: Central banks’ adjustments to benchmark interest rates have a diminishing impact on the market. If all economic activity occurs on a dollar basis, monetary policy effectively becomes paralyzed.
- Loss of Economic Data: When financial flows move off national control networks and onto blockchains, governments and policymakers lose the crucial data needed to understand economic conditions and formulate appropriate policies.
- Subordination to the US Economy: This results in national economies becoming entirely dependent on the monetary policy of the US Federal Reserve and fluctuations in the dollar’s value.
Paradoxically, this serves as a significant strategic advantage for the United States. The increasing global demand for dollar-pegged stablecoins necessitates that their issuers hold reserves in US dollars or US Treasury securities. This creates stable demand for US Treasury debt, contributing to the financing of America’s vast debt and further solidifying the dollar’s reserve currency status in the global financial system.
National Responses: Safeguarding Sovereignty with a ‘Two-Track Strategy’
In the face of the immense threat of digital dollarization, nations worldwide are employing a dual strategy to foster their own digital currency ecosystems: the ‘Two-Track Strategy’. This approach combines a top-down, government-led initiative with a bottom-up leveraging of private sector innovation.
Track 1: Fortifying the CBDC Bastion
The first strategy involves governments and central banks directly developing the most secure and trustworthy state-sanctioned digital currency: the Central Bank Digital Currency (CBDC). This is a strategy to build a “digital fortress” under national control, serving as the “last line of defense” against the invasion of the digital dollar. 
- China’s Digital Yuan (e-CNY): This is the most advanced example, aiming for strong state control. The Chinese government intends to gain access to all its citizens’ financial data through e-CNY, counter the influence of private big tech companies like Alipay and WeChat Pay, and lay the groundwork for challenging dollar hegemony by increasing the Yuan’s role in international trade settlement in the long run.
- Europe’s Digital Euro: The European Central Bank (ECB) is pursuing the digital euro with the dual aims of counteracting US dollar hegemony and the dominance of American tech giants like Google and Apple in the payment market. By emphasizing “privacy protection” as a core value, it strongly signals an intent to build an independent European digital economic sphere free from US surveillance.
Track 2: Cultivating ‘National Champion’ Private Stablecoins
While CBDC development involves complex processes of technical, legal, and societal consensus, requiring significant time, digital dollars are rapidly eroding the market in the interim. To respond more swiftly and flexibly, countries are also pursuing a parallel strategy of fostering ‘private stablecoins’ pegged to their national currencies, under government regulation and supervision.
- Japan’s Progmat Coin: The most prominent example of this strategy is Japan. The Japanese government is actively supporting the issuance of the Yen stablecoin ‘Progmat Coin’ by Mitsubishi UFJ Trust and Banking Corporation (MUFG), a leading global financial group. This initiative holds several sophisticated strategic objectives:
- Speed and Innovation: Private companies can respond to market changes and demands much more agilely than governments. By leveraging nimble private players, they aim to counter the speed of digital dollar adoption.
- Maintaining Monetary Sovereignty: While Progmat Coin is issued by the private sector, its value is pegged to the “Japanese Yen.” This means all economic activities conducted through this coin occur within the “Yen economic zone,” allowing the Bank of Japan to maintain the influence of its monetary policy while absorbing innovations in blockchain technology.
- Building a ‘Made in Japan’ Ecosystem: The Japanese government is encouraging its domestic companies to take the lead in new DeFi and Security Token Offering (STO) markets based on Yen stablecoins. This is part of an industrial policy aimed at preventing the outflow of financial data overseas and ensuring that domestic companies hold the reins of the future digital finance industry.
Ultimately, this two-track strategy is akin to an alliance between the government and the private sector against a common enemy: the “digital dollar.” The government lays down the “mat” of regulations and laws, while private companies perform the “dance” of innovation on it, expanding their nation’s digital currency territory.
The Payment Layer: The Heart of Future Finance ⚔️
The future of this currency war ultimately boils down to the question of ‘What money will be used for payments?’ The significance of this issue can be concretely illustrated through a scenario involving the tokenization of a popular cafe building in Seongsu-dong for fractional investment.
- Scenario 1 (Invasion of the Dollar Economic Zone): The building token issuer supports USDC payments to attract global investors. If a French investor purchases these building tokens with USDC, the transaction bypasses the Korean financial network entirely. A portion of the building’s rental income and capital gains leaks out of the Korean economy as dollar-denominated assets.
- Scenario 2 (Defending Monetary Sovereignty): The Korean government mandates the use of regulated ‘Won stablecoins’ or the future ‘digital Won (CBDC)’. Now, the French investor must first exchange their Euros or dollars for digital Won to purchase the building tokens. All transactions are conducted on a Won basis, allowing the Bank of Korea to transparently monitor and control the entire flow of funds.
Thus, the ‘payment currency’ for tokenized assets transcends mere convenience and becomes a strategic stronghold where the fate of a nation’s economy rests. The stablecoin regulations and CBDC development pursued by various countries are part of an intense competition to secure dominance over this payment layer.
