Interpolation Error

Calculation

Interpolation error, within cryptocurrency derivatives, arises from approximating a continuous function—representing an asset’s price or volatility surface—using discrete data points; this introduces discrepancies between the theoretical model and observed market values. In options pricing, particularly for exotic derivatives or those with limited liquidity, inaccurate interpolation can lead to mispriced contracts and suboptimal hedging strategies. The magnitude of this error is influenced by the interpolation method employed, the density of available data, and the inherent volatility of the underlying asset, demanding careful consideration in risk management protocols. Consequently, traders and quantitative analysts must assess the potential impact of interpolation error on portfolio valuations and trading decisions.
