Fiat currencies have different characteristics. Can stablecoin issuance be “one-size-fits-all”? ——Commenting on the HKD stablecoin issuance model
Author: Zhu Weisha, after Hong Kong's “Stablecoin Regulations” were introduced, I suggested in articles such as “The current method for issuing Hong Kong dollar stablecoins needs to be restructured” that the current plan has potential flaws (see the unlinked website for details). The purpose of this article is to further explain opinions from the perspective of fiat currency diversity and respond to readers' questions. The core argument is that there are fundamental differences in the credit base, circulation mechanism, and value stability of different fiat currencies, which determine that stablecoins are anchored, and their issuance method cannot be “one-size-fits-all.” What is particularly alarming is that the model of issuing stablecoins on top of what is already an anchor coin (such as the Hong Kong dollar) may amplify systemic risk. Cryptocurrency: A laboratory at the cutting edge of currency evolution In just 15 years, the cryptocurrency ecosystem has spontaneously evolved dozens of forms such as air coins, asset coins, trading coins, stablecoins, equity coins, governance coins, and NFTs, almost replicating the long process from original exchange to complex modern finance. This high-intensity, high-freedom testing ground has accumulated valuable insight into the nature of money, trust building, and value capture, and is undoubtedly a frontier position for human finance and monetary research and practice. If the implications of this “test field” are ignored, it may be difficult for regulatory policies to truly match the future of digital finance. There is an urgent need for financial practitioners to enter the cutting edge to make up for the shortcomings in their perception of cryptocurrencies. As one of the most successful applications of cryptocurrencies, fiat stablecoins have a design logic that not only relates to the issuance mechanism, but also requires a deep understanding of anchor characteristics and risk points. The introduction of the Hong Kong Stablecoin Ordinance reflects to some extent a lack of understanding of the relationship between stablecoins and anchors. A stablecoin is a type of transaction token, and a stablecoin linked to fiat is only one type of stablecoin. Compared to fiat currencies, it is very difficult to identify the “identity” of cryptocurrencies. There are often situations where one currency is used for two or more purposes. For example, Ethereum represents both trading and equity. If applied rigidly, the “collective investment plan” provisions of the current law may stifle innovation. The United States' exemption practice provides an example. Fiat money is simpler than cryptocurrency, but you also need to recognize its “color.” Identifying fiat currency: To understand fiat stablecoins in a “colorful” world, you must first understand their anchor—the huge difference between fiat currency itself: Fiat Currency (Fiat Currency) is a currency issued by relevant national (or regional) authorities to guarantee its legal status by law, and is supported by national credit. The strongest fiat currency is the basic currency. Standard currency (Standard Currency) originally meant “standard currency” in English. As the name suggests, it's a measure of the value of other fiat currencies. There are four conditions for becoming a basic currency under the condition of a floating exchange rate: 1. Stable value: Value is determined by the inflation rate. Theoretically, it is necessary to control the annual inflation rate of less than 2%. 2. Free global circulation: High degree of openness under capital. 3. It dominates global trade and financial settlements, and accounts for a significant share in global trade and financial settlements. 4. Central bank foreign exchange reserves: Occupies a large share of the market. The US dollar is currently the strongest fiat currency, and its credit stems from strong comprehensive national strength, deeply open financial markets, and global consensus. Therefore, the US dollar is the base currency. There are strong and weak basic currencies. Currently, only the US dollar is the strongest base currency, followed by the euro. The pound and yen are next. The settlement volume in RMB is not small, but it is a capital control that cannot circulate freely around the world and does not meet the definition of a basic currency. An anchor coin is a currency that anchors strong fiat currencies. The Hong Kong dollar is anchored to the US dollar through a linked exchange rate, so the Hong Kong dollar is an anchored currency, commonly known as a stablecoin. Vouchers are tickets, mainly for internal circulation. Tencent Q coins are a type of ticket. The principle of issuing RMB can be imagined as Q coins, but they are larger and more complex than the ecosystem of Q coins. Q coins only circulate in the Tencent ecosystem, and it is very inconvenient to circulate outward. The price of RMB refers to a basket of currency indices, and there is no public anchoring policy like the Hong Kong dollar. The RMB is a semi-market-based form of regulation. The amount of money in circulation around the world is limited (less than 3 trillion dollars, less than 1% of the broad RMB M2). The RMB circulates ecologically in China. Leaving aside the fiat currency shell issued by the RMB central bank, the RMB is an ecological voucher just like Q coins. The risk of issuing stablecoins “one-size-fits-all” is due to the fundamental differences in the underlying characteristics of fiat currencies. Using a logic that mimics the US dollar stablecoin issuance logic to issue various fiat stablecoins is unworkable, and may involve huge risks. Because the US dollar is the base currency, other currencies are not necessarily the base currency. The Hong Kong dollar is not the basic currency. The core problem of Hong Kong dollar stablecoins: The double superimposed risk structure The Hong Kong dollar itself is already a legal tender anchored to the US dollar, and its value stability depends on the linked exchange rate system. In addition to this, another “Hong Kong dollar stablecoin” claiming to be 1:1 anchored to the Hong Kong dollar will be issued,...
