Stablecoin Depeggings: Risks and Lessons Learned

Stablecoins have achieved a remarkable milestone, with their total market capitalization now surpassing $300 billion. As of early October 2025, this sector represents a substantial part of the digital asset landscape.

Despite this impressive growth, stablecoins have yet to achieve truly mainstream adoption. A primary reason for this is the recurring incidents where these digital assets fail to maintain their intended value, deviating from the assets that are supposed to back them – whether that’s fiat currencies, commodities, or other cryptocurrencies.

This discussion delves into real-world examples of stablecoin depegging events, explores the underlying causes, outlines the inherent risks, and considers potential strategies issuers can implement to enhance stability and prevent such occurrences.

Pro tip: Regularly check the reported reserves and audit reports of stablecoin issuers to ensure transparency and a solid backing for the tokens you use.

Historical Overview of Stablecoin Depegging Incidents

The history of stablecoins is punctuated by events that have exposed inherent weaknesses in their design and operational models. Early examples, such as the difficulties faced by unbacked algorithmic models, demonstrated their inherent fragility. Even widely-used stablecoins have experienced brief periods below their target value, often triggered by market volatility and temporary liquidity shortages, which inevitably fuel concerns about the adequacy of their reserves.

Consider this: When looking at stablecoins, pay close attention to their historical performance during periods of high market stress; this often reveals their true resilience.

One of the most significant collapses occurred in May 2022, when a prominent algorithmic stablecoin experienced a catastrophic unraveling. A wave of redemptions initiated a downward spiral, leading to hyperinflation of its sister token and wiping out billions in market value. This event sent shockwaves throughout the entire crypto industry, highlighting the systemic risks associated with certain stablecoin designs.

Here’s something practical: Ensure you understand the specific mechanism a stablecoin uses to maintain its peg, whether it’s algorithmic, fiat-backed, or asset-collateralized, as each carries unique risks.

Even stablecoins backed by traditional assets have faced challenges maintaining their peg. Instances of depegging have occurred following major events, such as the collapse of significant financial institutions, underscoring how even reserves held in fiat can be subject to traditional financial system risks. Other stablecoins, partially backed by these affected assets, also experienced dips, deepening concerns about interdependencies across the stablecoin market.

You can also: Diversify your stablecoin holdings across different issuers and backing mechanisms to mitigate risks associated with any single point of failure.

Collectively, these episodes underscore persistent challenges related to liquidity, confidence erosion, and systemic vulnerabilities that continue to affect stablecoins, even as the sector approaches significant market capitalization milestones.

A good idea is to: Always be aware of the underlying collateral and the issuer’s financial health when choosing a stablecoin.

Did you know? Frequent depegs occur when liquidity pools become depleted. Significant sell-offs can drain available liquidity, making recovery more challenging. Market events have shown how limited depth in trading pools can amplify the impact of price shocks.

Quick note: Research the liquidity depth of stablecoin trading pairs on exchanges you frequent to gauge their susceptibility to large price swings.

Case Study: The TerraUSD Collapse

The dramatic collapse in May 2022 was a pivotal moment for the digital asset market. This event triggered a cascading series of negative effects across the industry and starkly revealed the risks associated with algorithmic stablecoins. Unlike traditional stablecoins that rely on direct fiat backing, this particular asset attempted to maintain its $1 peg through a complex arbitrage mechanism with its associated token.

Pro tip: Be wary of stablecoin protocols promising excessively high and seemingly unsustainable yields, as these can often mask underlying risks.

The adoption of this stablecoin was significantly boosted by associated protocols offering exceptionally high, subsidized yields to depositors. However, as scrutiny of this model intensified and broader cryptocurrency markets faced downturns, confidence began to erode, leading to a bank-run-like scenario. Sophisticated investors were among the first to exit, accelerating the stablecoin’s loss of its peg. The initial warning signs emerged when substantial withdrawals from key platforms occurred, signaling an impending crisis.

Consider this: During periods of market stress, observe on-chain data for significant withdrawal patterns or unusual token minting activity as potential early indicators of trouble.

This initiated a massive volume of trades converting the stablecoin to its volatile sister token. In a very short period, the supply of the sister token surged exponentially, while its price plummeted towards zero, completely shattering the stablecoin’s intended peg. The crash exposed critical flaws within decentralized finance (DeFi), including the unsustainability of unrealistic yield models and the disproportionate impact on less informed retail investors who often bore the brunt of the losses.

Here’s something practical: Educate yourself on the mechanics of algorithmic stablecoins, as their stability mechanisms can be complex and prone to failure under specific market conditions.

Did you know? The speed at which confidence can dissipate in the crypto space, often amplified by online discussions, was clearly demonstrated during this collapse. Fear can spread rapidly, leading to swift and significant market reactions.

Case Study: Yala’s YU Stablecoin Incident

In September 2025, a Bitcoin-backed stablecoin experienced a depegging incident that appeared to follow an exploit. Blockchain analysis indicated that a malicious actor may have manipulated the protocol by minting a large quantity of the stablecoin tokens on a specific network. Subsequently, these tokens were moved and sold for other stablecoins across different blockchain networks.

A good idea is to: Stay informed about security audits and exploit reports related to stablecoin protocols and their underlying infrastructure.

Following these actions, the attacker systematically converted the received stablecoins into widely traded cryptocurrencies and distributed them across multiple wallets. A significant portion of the depegged stablecoin tokens remained on various networks, with some unbridled.

Quick note: Understand the cross-chain functionalities of stablecoins, as bridging mechanisms can sometimes introduce additional security risks.

The protocol’s development team confirmed that the underlying asset collateral remained secure. However, the stablecoin struggled to recover its intended peg. In response, key functions were temporarily disabled, and investigations were initiated in collaboration with security experts.

Pro tip: Look for stablecoins that have undergone rigorous security audits from well-respected firms, as this indicates a commitment to security best practices.

This event highlighted a critical vulnerability: despite a substantial market capitalization, the stablecoin exhibited very shallow liquidity on-chain, making it susceptible to precise strategic attacks. By mid-September 2025, the stablecoin had indeed managed to regain its intended peg on certain decentralized exchange platforms.

Why Stablecoins Can Fail to Maintain Their Peg

The fundamental aim of stablecoins is to preserve a consistent value. However, historical performance demonstrates that they can indeed lose their $1 peg during periods of market stress. These failures often stem from a combination of design limitations, shifts in market sentiment, and external pressures that can expose weaknesses, even in systems that appear robust.

Consider this: The stability of a stablecoin is intrinsically linked to the overall health and liquidity of the cryptocurrency market.

Key factors contributing to depegging events include:

• Liquidity Shortages: When trading pools lack sufficient funds, large sell orders can trigger significant price drops. The limited liquidity in certain trading pairs has repeatedly demonstrated its role in fueling instability.

• Erosion of Trust and Runs: Public panic can initiate scenarios resembling traditional bank runs. Once confidence wavers, widespread withdrawals can drive prices down, and negative sentiment or amplified market reactions can accelerate this downward spiral.

• Algorithmic Design Flaws: Mechanisms that rely on mint-and-burn operations can falter when redemption demands outstrip the protocol’s capacity to manage them. Exploits or sudden market shocks can easily destabilize these inherently fragile designs.

• External Economic Pressures: Broader financial crises, such as major bank failures, significant hacks, or economic downturns, can place strain on pegs across the entire market, intensifying volatility and systemic risks.

Here’s something practical: Seek out stablecoins that utilize over-collateralization or transparent, verifiable reserve mechanisms as a safeguard against unexpected market fluctuations.

Did you know? To bolster stability and prevent future depegging, projects are actively exploring approaches like proof-of-reserves, enhanced collateralization ratios, and real-time, independent audits. These innovations represent a shift towards more transparent and trust-building mechanisms, though investors understand that absolute price stability in the crypto world is never wholly guaranteed.

Risks Investors Cannot Overlook

While stablecoins are intended to provide a reliable store of value, their occasional failure to maintain their peg can introduce significant risks for individual investors and the broader digital asset ecosystem. It is crucial for investors to be aware of these potential pitfalls:

• Financial Losses: Depegging events can lead to permanent erosion of value. In the context of stablecoins, the potential for rapid value loss can exceed that of traditional financial instruments, increasing the risk of capital loss for investors.

• Security Vulnerabilities: Attacks, such as those involving the unauthorized minting of tokens, can lead to assets being dispersed across different blockchains, often leaving investors with minimal prospects for recovery.

• Regulatory and Reputational Scrutiny: As the stablecoin market expands significantly, major participants are facing increased regulatory attention. This scrutiny raises questions about the long-term financial stability of issuers and highlights the limitations in achieving widespread market adoption.

• Systemic Market Impacts: The failure of a single stablecoin can trigger widespread disruptions across the market. Past events have demonstrated how the collapse of one asset can destabilize interconnected DeFi systems, amplifying the damage throughout the entire crypto ecosystem due to the interconnected nature of these risks.

Lessons Learned from Stablecoin Failures

The repeated instances of stablecoin failures have served as important lessons, illustrating both the potential utility and the inherent fragility of digital assets designed to track a specific value. Each collapse has underscored how factors such as liquidity deficits, inadequate collateral, and an over-reliance on complex algorithms can rapidly undermine user confidence.

A good idea is to: Prioritize stablecoins backed by over-collateralized reserves and verifiable high-quality liquid assets to enhance stability during market stress.

To mitigate these risks, issuers can concentrate on enhancing collateral structures by adopting over-collateralized models and utilizing assets that are both high-quality and liquid. Transparency remains paramount. Implementing robust proof-of-reserves, undergoing regular independent audits, and providing clear disclosures regarding reserves and redemption processes are crucial steps in rebuilding and maintaining trust. Additionally, establishing reserve funds can help absorb sudden large sell-offs and stabilize the intended peg.

Pro tip: Understand the redemption process for the stablecoins you use; clear and accessible redemption policies are vital for investor confidence.

On a technical level, conducting comprehensive smart contract audits, employing multi-signature controls for enhanced security, and limiting exposure through cross-chain interactions can effectively reduce security risks. Furthermore, establishing strong governance frameworks, aligning with evolving regulatory standards, and potentially securing insurance coverage can provide additional layers of protection and bolster investor confidence.
