Explanation:
Jump approaches are more suitable for modeling wrong-way risk (WWR) during market stress because they can effectively capture sudden, discontinuous market movements (jumps). During such severe stress events, margin and collateral processes often fail to provide sufficient coverage due to the rapid speed and magnitude of market changes, rendering them less effective. Continuous approaches (like intensity or structural models) tend to assume smoother market movements where margin requirements can be adjusted over time, leading to an overestimation of collateral effectiveness during jumps. Therefore, to reflect the limited impact of collateralization under severe stress scenarios, Hudson should prefer jump approaches.

Q.5483 In the financial market trading sector, Hudson Capital Inc. has noticed patterns of collateral becoming less effective during times of market stress, particularly in their foreign exchange (FX) portfolio. The risk management team is considering which modeling approach could better reflect their observations for wrong-way risk (WWR). How should Hudson adjust their modeling method for collateral valuation, according to the recent market volatility and the effectiveness of collateral during WWR?
A
Hudson should lean towards continuous approaches like intensity and structural approaches for collateral valuation, as these tend to show that margin is effective in mitigating WWR.
B
Hudson should prefer jump approaches for WWR modeling, as these have been found to reflect the limited impact of collateralization during market jumps.
C
Hudson should utilize parametric approaches exclusively, as these methods provide a clear-cut measure of collateral effectiveness without considering market jumps.
D
Hudson should disregard recent market volatility and continue using their current modeling approach for collateral, as WWR is not significantly influenced by market changes.
