Analysis of Backing Models and Systemic Risks

1. The Systemic Relevance of Stablecoins

Stablecoins function as a crucial infrastructure component in the digital asset market. They serve not only as a store of value in times of high volatility but primarily as a liquidity bridge between the traditional fiat system and the blockchain economy.

The core function is interoperability: they enable the settlement of transactions on-chain without having to leave the ecosystem. For investors, however, a fundamental question arises: how resilient is the peg to the underlying currency (usually the US dollar) during stress phases? The answer lies in the structure of the respective stablecoin.

2. Classification of Stability Mechanisms

The market can be divided into three primary categories, which differ fundamentally in terms of their backing and risk profile:

1. Fiat-Collateralized: Centrally issued and backed by traditional assets (cash, government bonds).
2. Crypto-Collateralized: Decentralized issued and over-collateralized by other cryptocurrencies.
3. Algorithmic: Stabilization through money supply control and incentive mechanisms without external collateral.

Fiat-Collateralized: Counterparty Risk

With fiat stablecoins (e.g., USDC, USDT), a central entity issues tokens against deposits. Security depends exclusively on two factors: the solvency of the issuer and the quality of the held reserves.

The risk is a classic issuer and counterparty risk. If the reserves are not present 1:1 or are stuck in illiquid assets (maturity mismatch), a "bank run" can lead to insolvency. Additionally, there is the risk of regulatory intervention (freezing of funds) since these systems are centrally controlled.

Crypto-Collateralized: The Volatility Trap

Protocols like MakerDAO (DAI) use smart contracts to issue stablecoins against crypto collateral (e.g., ETH). To cushion the volatility of the collateral, over-collateralization is required.

The risk here lies less in a central party but in market dynamics and technology. A rapid decline in the value of collateral can lead to mass liquidations, which further depress the price ("liquidation cascade"). Furthermore, there is the persistent risk of bugs in the smart contract code.

Algorithmic: Experimental Monetary Policy

Algorithmic stablecoins attempt to stabilize the price by automatically adjusting supply and demand. These models often forgo full backing ("under-collateralized").

Historically, these models have proven to be highly fragile. The risk is that of a loss of confidence (confidence crisis), leading to a "death spiral" where the stabilization mechanism fails due to massive selling pressure. For conservative risk strategies, these instruments are generally unsuitable.

3. Historical Analysis of Market Failures

The history of stablecoins offers important lessons for risk management:

Reserves and Transparency (USDT):
Tether (USDT) has repeatedly faced questions regarding the composition of its reserves. The lack of complete, independent audits creates an information asymmetry that must be priced in by the market as a risk.

Banking Risk (USDC):
In March 2023, USDC briefly lost its parity (depeg) because a portion of the reserves was held at the insolvent Silicon Valley Bank. This illustrates that fiat-backed stablecoins are also exposed to the risks of the traditional banking sector.

Design Flaws (Terra/UST):
The collapse of TerraUSD (UST) in 2022 demonstrated the failure of purely algorithmic models without external intrinsic value. Billions in market capitalization were wiped out as the stabilization mechanism collapsed in a downward spiral.

Conclusion: Technical complexity is no substitute for liquid collateral. Due diligence must examine the quality of the assets and the legal structure.

4. Regulatory Perspective

Stablecoin regulation is in flux. With the Markets in Crypto-Assets Regulation (MiCA) in the EU, strict requirements are being placed on issuers, particularly regarding capital reserves and redemption rights.

For investors, regulation means, on the one hand, more legal certainty (reduction of default risk), but on the other hand, potential restrictions on usage (e.g., limits on transaction volumes or KYC requirements for DeFi usage). Future stablecoins will likely be strongly oriented towards these regulatory frameworks ("compliant stablecoins").

5. Risk Mitigation Strategies

Professional risk management in the stablecoin sector should never rely on a single asset. Diversification is essential to avoid cluster risks.

Portfolio Structuring in the Current Market Environment

A robust allocation could consider the following components:

Core Liquidity (Conservative):

• USDC / Regulated Euro Tokens: Focus on transparency, auditing, and regulatory compliance. Low yield potential, high security.

Market Liquidity (Aggressive):

• USDT: Often necessary due to high market dominance and liquidity on exchanges, but considering the transparency risk.

Decentralized Hedging:

• DAI / LUSD: Use of over-collateralized, decentralized options to reduce censorship risks and dependence on the banking sector.

6. Conclusion: Differentiated View Necessary

Stablecoins are not a homogeneous asset class. The differences in backing, legal structure, and technical architecture significantly determine the risk profile.

For institutional investors: Trust is good, verification is better. A deep understanding of default mechanisms (liquidity, solvency, technology) is a prerequisite for the safe use of digital central bank money substitutes.
