## Portfolio Fungibility

Portfolio fungibility is the principle that all units of capital within an investment account are identical and interchangeable, regardless of how they were acquired or their intended purpose. In professional trading, treating capital as fungible is essential for accurate risk assessment and optimal allocation.

When traders violate this by mentally partitioning funds, they create inefficiencies and increase the probability of ruin. For instance, holding a high-risk derivative position while keeping a separate cash bucket for safety is mathematically equivalent to holding a lower-risk overall portfolio.

Understanding fungibility allows for the implementation of a unified risk management strategy that optimizes the Sharpe ratio of the entire account. It ensures that capital is allocated to the highest expected return opportunities relative to risk, regardless of the psychological label attached to the money.

This concept is foundational to quantitative finance and modern portfolio theory.
