Speed of Light Constraints

Constraint

Speed of light constraints, within financial markets, represent a fundamental limitation on information propagation and, consequently, arbitrage opportunities. This physical boundary dictates the minimum time required for market participants to react to new information, creating a temporal asymmetry exploited by high-frequency trading firms. The impact is particularly pronounced in fragmented markets, where latency differences between exchanges can determine profitability, and is a critical consideration in the design of market microstructure.
