Basis Spread Risk
Basis Spread Risk is the uncertainty associated with the difference between the spot price of an asset and its derivative price. In crypto, this spread is driven by market sentiment, demand for leverage, and the cost of capital.
If the basis narrows or turns negative unexpectedly, an arbitrageur's expected income from funding rates may evaporate or turn into a loss. This risk is particularly acute during periods of high volatility when the correlation between spot and derivative markets can break down.
Traders must constantly monitor the basis to adjust their hedges and ensure that their strategy remains market-neutral. If the basis moves against the trader, they may face margin calls on their short position despite having a hedged spot position.
Managing this risk involves analyzing historical basis patterns and the impact of broader macro-crypto correlations on market sentiment.
