AB This is an investigation of whether the same finite-dimensional system spans both interest rates (the yield curve) and interest rate options (the implied volatility surface). The options market is found to exhibit factors seemingly independent of the underlying yield curve. While three common factors are adequate to capture the systematic movement of the yield curve, three additional factors are needed to capture the movement of the implied volatility surface. Simulation analysis confirms the robustness of these findings.
