The rapid growth of cryptocurrencies, led by Bitcoin, has also fueled the rise of stablecoins, which are generally considered less volatile. However, the recent depegging of TerraUSD (UST)—the world’s third-largest stablecoin—from the US dollar, along with the near-complete collapse of LUNA, has drawn significant market concern. What led to this stablecoin crisis? Does this signal that stricter regulation of stablecoins and cryptocurrencies is inevitable?
The TerraUSD and LUNA Collapse: What Happened?
Terra’s blockchain platform revolved around two main assets: the UST stablecoin and the LUNA cryptocurrency. UST was designed to maintain a 1:1 peg with the US dollar, while LUNA’s value was variable. The system relied on an algorithmic mechanism where minting a new UST required burning the equivalent of $1 in LUNA, and vice versa.
This setup allowed investors to arbitrage price differences. When UST traded above $1, users could buy LUNA worth $1 to mint UST and profit. Conversely, if UST fell below $1, investors could buy UST at a discount and exchange it for $1 worth of LUNA.
Triggers of the Crisis
Unlike asset-backed stablecoins, which hold reserves like fiat currency or bonds, UST and LUNA relied primarily on market confidence and algorithmic balancing—a model with inherent fragility. According to industry experts, a major factor in their popularity was the Anchor Protocol, which offered a 20% annual yield for UST deposits. At its peak, about 75% of all UST in circulation was held in Anchor, attracting both retail and leveraged investors.
However, shifting macroeconomic conditions played a decisive role. US monetary tightening policies contributed to declines in both equity and cryptocurrency markets. Simultaneously, the Luna Foundation Guard (LFG) withdrew $150 million in UST to bolster reserves, reducing market liquidity.
The situation escalated in early May when a large investor sold approximately $84 million in UST, triggering a loss of peg. Panic selling ensued, and UST’s price plummeted. LUNA, intrinsically linked to UST, fell from around $80 to nearly zero in just three days—a collapse of 99.9%.
The Domino Effect on the Crypto Market
In an attempt to stabilize UST, LFG began selling a significant portion of its Bitcoin reserves. Unfortunately, this occurred during a broader market downturn, accelerating Bitcoin’s decline and worsening conditions across the cryptocurrency ecosystem.
The crash eroded investor confidence, not only in algorithmic stablecoins but in the broader crypto market. It underscored the need for improved risk management among investors and clearer regulatory frameworks from authorities.
The Push for Regulatory Oversight
The Terra-LUNA collapse has intensified calls for regulation. US Treasury Secretary Janet Yellen cited the incident as evidence of the risks stablecoins pose to financial stability and urged lawmakers to advance regulatory legislation.
In response, jurisdictions worldwide are reevaluating their stance on digital assets. Hong Kong, for example, is moving toward a licensing regime for cryptocurrency exchanges. Starting in 2023, only licensed platforms will be permitted to offer services in the city.

Cryptocurrency Basics: Opportunity and Risk
Since the launch of Bitcoin in 2009, cryptocurrencies have introduced transformative possibilities across finance, technology, and digital ownership. Today, thousands of cryptocurrencies are traded globally, attracting investors with their potential for high returns—and high volatility.
The Rise of Bitcoin and NFTs
Bitcoin emerged in the aftermath of the 2008 financial crisis, envisioned as a decentralized digital currency. Its value has grown exponentially—from being worth a few cents to tens of thousands of dollars per coin.
This concept of digital scarcity also paved the way for Non-Fungible Tokens (NFTs), which are used in art, gaming, identity verification, and certification. The growing accessibility of NFT minting is fostering new forms of digital asset creation.
Challenges Facing Crypto Adoption
Despite its potential, cryptocurrency faces significant challenges. Its decentralized and pseudonymous nature has attracted illicit activities, prompting strict Know Your Customer (KYC) protocols on major exchanges. These measures, while necessary, can limit user growth and revenue.
Moreover, the absence of central backing makes cryptocurrencies highly sensitive to market sentiment, news, and government actions. Investors face risks such as exchange failures, with limited avenues for legal recourse or compensation.
The Future of Crypto in Hong Kong and Beyond
Hong Kong’s established status as a global financial center, with robust capital flows and mature markets, positions it as a potential hub for cryptocurrency innovation. The coming regulatory clarity is expected to foster healthier market development.
Globally, leading exchanges are enhancing security protocols and compliance measures to protect users and align with emerging regulations. The industry is evolving toward greater accountability and stability.

Frequently Asked Questions
What is a stablecoin?
A stablecoin is a type of cryptocurrency designed to maintain a stable value, typically pegged to a fiat currency like the US dollar. Some are backed by reserves, while others use algorithms to control supply and demand.
Why did UST lose its peg?
UST’s depegging was caused by a combination of large sell-offs, reduced liquidity, and loss of market confidence. The algorithmic mechanism that was supposed to stabilize it couldn’t withstand the extreme market conditions.
Are all stablecoins risky?
Not all stablecoins carry the same level of risk. Those backed by sufficient fiat or bond reserves are generally considered safer than algorithmic stablecoins, which depend on code and market activity to maintain stability.
How can investors protect themselves?
Investors should research thoroughly, avoid over-leveraging, and diversify investments. Understanding the underlying mechanism of any cryptocurrency is crucial before investing.
Will cryptocurrencies be regulated?
Increased regulation is highly likely. Many countries are drafting laws to govern digital assets, focusing on consumer protection, financial stability, and anti-money laundering measures.
What is the future of cryptocurrencies?
While the market is maturing, cryptocurrencies continue to hold potential for innovation in decentralized finance, digital ownership, and cross-border transactions. Regulatory clarity may lead to more sustainable growth.
Cryptocurrency represents a new generation of digital transaction mediums. Using blockchain technology, it ensures security and controls the creation of new units. Bitcoin, the first cryptocurrency, was launched in 2009. Since then, thousands of alternatives—such as Ethereum, Ripple, and Litecoin—have emerged.
It’s important to note that cryptocurrencies are not issued or backed by any central bank or government. In Hong Kong, they are treated as virtual commodities, not legal tender, and are not widely accepted for everyday transactions.
