Stability Research


This transcript is from the third and final video of the CBBC series on stable coins, focusing on simulating stable coin risks. It aims to provide regulators, researchers, and international organizations with insights into stable coin technology design and policy considerations.

Types of Stable Coins and Risk Factors

The video begins with a recap of the different types of stable coins discussed in the previous videos. These include fiat collateralized, commodity collateralized, crypto collateralized, seniority share, and programmatic stable coins. Each type has its unique risk factors.

Simulating Stable Coin Risks

The video delves into the process of simulating stable coin risks and analyzing their environment. It emphasizes the importance of understanding risk factors specific to different types of stable coins. For fiat collateralized stable coins, the major risks lie in the collateral and the counterparty storing it. Other stable coins have unchanged collateral, making them more transparent, but present risks related to supply and demand dynamics.

Modeling and Analysis

The next part of the talk explores how to analyze stable coins through simulation. It discusses the use of stochastic processes, such as geometric Brownian motion, to model risk scenarios. It highlights the need to consider various factors, such as demand fluctuations and future behavior of the crypto market, while acknowledging the limitations of historical data and normal distribution assumptions.

Geometric Brownian Motion

The video explains the concept of geometric Brownian motion as a commonly used stochastic process for analyzing market behavior. It demonstrates how different mean values and parameters can result in various scenarios, but notes that this process may not fully capture extreme market jumps or heavy-tailed distributions.

Geometric Ornstein-Uhlenbeck Process

In contrast to geometric Brownian motion, the video introduces the geometric Ornstein-Uhlenbeck process as an alternative with a stationary distribution. It demonstrates how this process can better represent extreme market behavior and provides a wider range of scenarios. However, it also acknowledges that this process may not account for extreme jumps observed in the crypto market.

Including Jumps in Analysis

To address extreme market behavior, the video suggests including jump terms in the stochastic processes. It mentions idiosyncratic jumps and market-wide jumps and highlights the importance of considering heavy tails and extreme returns. By incorporating jumps, analysts can generate a broader range of scenarios that better capture the dynamics of the crypto market.

Conclusion and Further Reading

In conclusion, the video summarizes the key points covered in the series, including stability mechanisms and risk factors of different stable coins. It mentions specific examples like Celo and highlights the need for simulating stable coin stability. The video concludes by providing a link to the stability paper and encourages further reading on the subject.
