Basis Risk Propagation

Basis risk propagation refers to the process by which discrepancies between the spot price of an asset and the price of its derivative contract transmit stress across markets. When the basis, or the difference between the two prices, widens unexpectedly, it can trigger margin calls or force hedging adjustments.

This is particularly prevalent in perpetual futures, where the funding rate is designed to keep the contract price anchored to the spot price. If the mechanism fails, the resulting basis volatility can cause significant losses for traders who are hedged.

The propagation aspect occurs when these losses force market participants to sell their spot holdings, further impacting the spot price and creating a feedback loop. Analyzing this propagation is vital for understanding how derivative markets influence the underlying asset.

It highlights the interdependence between spot liquidity and derivative market stability.
