UST (TerraUSD) was once one of the widely known stablecoins in the cryptocurrency market, however its stability suffered a major crisis in 2022, resulting in a large number of user and investor losses. This article will provide an in-depth analysis of UST Coin's features, principles of operation, and its application in the cryptocurrency space, as well as a review of its performance and the reasons for its collapse. This paper aims to help readers better understand the historical background of the UST, its characteristics, and its impact on the stablecoin market.
Basic Introduction of UST Coin
UST (TerraUSD) is a stablecoin based on the US dollar, originally issued by Terraform Labs on the Terra blockchain. As a stablecoin, UST aims to maintain a 1:1 peg to the US Dollar, meaning that each unit of UST should theoretically equal 1 US Dollar. Unlike other stablecoins such as Tether (USDT) or USD Coin (USDC), UST does not rely on fiat reserves, but instead uses an algorithmic stabilization mechanism to maintain its value.
This mechanism maintains stability by exchanging UST and LUNA (another token on the Terra blockchain). When the price of UST falls below $1, users can exchange 1 unit of UST for LUNA and vice versa, thus realizing the balance between supply and demand in the market and maintaining price stability.
This mechanism did not work effectively in practice to cope with large-scale market fluctuations, ultimately leading to the 2022 crash, which had a severe impact on the market and users.
Operation Mechanism of UST
The core operating principle of UST is based on the concept of "Algorithmic Stabilization Currency". This means that the value of the UST is not backed by a centralized institution or pool of funds, but by a set of automated algorithms that regulate its supply to maintain price stability.
When the UST price deviates from $1, the Terra blockchain automatically adjusts the supply in an attempt to restore stability. For example, if the UST price is below $1, users can swap UST for LUNA, which reduces the supply of UST in the market and theoretically pushes up its price. On the other hand, if the price of UST is higher than US$1, users can exchange LUNA for UST, which will increase the supply of UST in the market and thus depress the price.
This automated mechanism allowed UST to theoretically respond quickly to market fluctuations and maintain its peg to the U.S. dollar. In May 2022, this mechanism failed due to a massive market sell-off, causing the price of UST to plummet below $1 and the value of LUNA to plummet as well.
Background and Causes of the UST Crash
In May 2022, UST experienced dramatic price fluctuations in just a few days, which eventually caused its price to plummet. One of the main reasons for this event was a severe inflationary problem with the LUNA tokens on the Terra blockchain. When the market's confidence in UST collapsed, the supply of LUNA expanded rapidly, causing LUNA's value to plummet.
More specifically, when large-scale investors started selling UST, the Terra blockchain algorithm was designed to require that a large number of LUNAs be printed in order to maintain the stability of UST, which caused a dramatic increase in the supply of LUNAs and further exacerbated the panic in the market. Ultimately, this resulted in the UST losing its peg to the US dollar and the price of LUNA falling to almost zero, further exacerbating the overall market turmoil.
Features and Risks of UST
Theoretically, the most important feature of UST as an algorithmic stablecoin is that it is decentralized and does not need to rely on traditional fiat currency reserves to maintain its stability. Because it runs on the Terra blockchain, UST can be traded quickly and used in a variety of decentralized financial (DeFi) applications such as lending, trading and liquidity provision.
As the 2022 crash demonstrated, UST also carries significant risks. The design of an algorithmic stablecoin is inherently dependent on the trust of the market and the balance between supply and demand, and the algorithmic mechanism will not be able to effectively maintain its stability in the event of a collapse of trust in UST. the interrelationship between UST and LUNA allows for a complex risk transfer mechanism between the two, so that when one side is subject to severe fluctuations, the other side is also affected, which exacerbates the instability in the system as a whole.
The Impact of the UST Collapse on the Market
The collapse of UST has sent shockwaves through the cryptocurrency market. As a massively used stablecoin, the collapse of the UST left a large number of funds and assets tied to it in dire straits, particularly in the DeFi platform, where many projects that relied on the UST for liquidity suffered as a result.
The collapse of UST also triggered a crisis of confidence in stablecoins in the market. Many investors began to question the viability of algorithmic stablecoins and turned to more stable and transparent options such as fiat-guaranteed stablecoins like USDC and USDT. This incident has prompted regulators to pay more attention to and discuss stablecoins in the cryptocurrency market, especially in the areas of regulation and risk management of stablecoins.
UST Application Scenarios
Despite the controversy surrounding the collapse of UST, its former application still provides some important insights into the cryptocurrency space. As a stablecoin, UST was widely used in the DeFi ecosystem, with many decentralized financial platforms utilizing UST to provide stable assets for operations such as lending, liquidity provision, and revenue farming.
UST has also played an important role in various payment and transaction applications on the Terra blockchain. Due to its stability, UST was considered an ideal payment tool for fast, low-cost cross-border payments. Even so, the collapse of UST has led to a rethinking of the risks and application boundaries of stablecoins in decentralized finance.
Conclusion: The Future of UST and the Challenges of Stabilized Currency Markets
The collapse of UST has raised questions about the viability of algorithmic stablecoins and highlighted the challenges facing the stablecoin market. Although UST had its place in the cryptocurrency market, its collapse has reminded investors that the mechanism of stabilization and the trust of the market are of paramount importance.
For the future, the development of the stablecoin market is likely to focus more on regulatory compliance, risk management and transparency. Traditional fiat-guaranteed stablecoins such as USDC and USDT are likely to continue to be favored, while algorithmic stablecoins will need to undergo more validation and adjustments in order to rebuild market trust.
For cryptocurrency investors in Taiwan, it is crucial to understand the risks and characteristics of different stablecoins. Whether choosing a fiat-guaranteed stablecoin or an algorithmic stablecoin, it is important to evaluate carefully and make decisions based on market changes and risk management strategies.
