We analyze the co-movement between the Credit Default Index (CDX) curve and the S and P 500 index's option volatility surface. We connect the reduced-form no-arbitrage model with the Nelson-Siegel (N-S) model on hazard rate implied from the CDX curve, and identify the levels, slopes, and curvatures from these two markets via the Unscented Kalman Filter (UKF). We find that the changes in the level, slope, and curvature in the CDX curve and those in the volatility surface are correlated due to the bridge of the S and P 500 index return. Finally, the co-movement between the CDX curve and S and P 500 index's volatility surface become stronger after the late 2000s global financial crisis.
