Paper: Tokenomics: How ‘Risky’ Are the Stablecoins? Authors: Shah, Anand and Bahri, Anu Date: January 2023 Estimated Reading Time: 90 minutes

The study introduces a novel risk measure for stablecoins based on the likelihood of their value reaching a critical threshold, potentially leading to a "break the buck/death spiral" scenario. The study utilizes various models, including Vasicek CIR, ARMA+GARCH, and Vasicek+GARCH, to evaluate and compare the risk and volatility of stablecoins against traditional cryptocurrencies like Bitcoin, the NASDAQ composite, and fiat currencies like the EURO. It identifies that asset-backed stablecoins (e.g., Tether, USD Coin, Binance USD, True USD) are generally less risky than decentralized algorithmic stablecoins like FRAX and cryptoasset-backed stablecoins like DAI. The research suggests significant implications for stablecoin issuers and regulators in setting capital requirements to mitigate these risks.

Core Insights:

The research presents a nuanced view of stablecoin stability and risk, distinguishing between asset-backed, algorithmic, and cryptoasset-backed stablecoins. The introduction of a specific risk measure for stablecoins, emphasizing the probability of value depreciation to a critical threshold, highlights a sophisticated approach to assessing the inherent risks of these digital assets. This measure is crucial for understanding the conditions under which stablecoins can maintain their peg to underlying assets or currencies and when they might fail.

The differentiation in risk levels among various types of stablecoins sheds light on the complex dynamics within the stablecoin market. Asset-backed stablecoins exhibit lower risk levels due to their backing by tangible assets or fiat currencies, offering a more stable and less volatile alternative to traditional cryptocurrencies. In contrast, algorithmic and cryptoasset-backed stablecoins, which rely on more complex mechanisms to maintain their value, present higher risks. This distinction is pivotal for investors, regulators, and issuers in making informed decisions and managing risks effectively.

Furthermore, the comparison of stablecoin volatility against traditional financial assets and cryptocurrencies provides valuable insights into their behavior in different market conditions. The findings suggest that while stablecoins generally offer a more stable option compared to cryptocurrencies like Bitcoin, they are not immune to market dynamics and can exhibit significant volatility during crisis events. This aspect is crucial for developing comprehensive risk management strategies that can withstand market fluctuations and protect investor interests. The study’s policy implications for stablecoin issuers and regulators are particularly noteworthy. It underscores the importance of setting appropriate capital requirements and regulatory frameworks to mitigate the risks identified through the novel risk measure. These policy recommendations aim to ensure the stability and reliability of stablecoins as a digital asset class, addressing potential vulnerabilities that could lead to destabilizing events like a "death spiral." However, this analysis raises several critical questions for further exploration:

In conclusion, the document provides a comprehensive analysis of stablecoin risks, offering a foundational framework for assessing and managing these risks in the digital asset space. The insights derived from this study are instrumental in guiding policy development, regulatory initiatives, and strategic decision-making for stablecoin issuers and investors. As the stablecoin market continues to evolve, ongoing research and collaboration among stakeholders will be essential to enhancing the stability and resilience of these digital assets in the broader financial ecosystem.
