Risk-Free Asset Assumption

Assumption

The risk-free asset assumption, central to many derivative pricing models, posits the existence of an investment with a known, constant return over a specified period, serving as a benchmark for discounting future cash flows. Within cryptocurrency markets, identifying a true risk-free asset presents a significant challenge due to inherent volatility and counterparty risks, often necessitating the use of stablecoins or highly-rated sovereign debt as proxies. This assumption underpins option pricing models like Black-Scholes, adapted for crypto, and influences hedging strategies employed by traders managing exposure to digital assets. Consequently, deviations from this assumption introduce model risk and necessitate adjustments to valuation and risk management frameworks.
