Detecting the risk of cross-product manipulation in the EUREX fixed income futures market

Cross-product manipulation involves manipulating one financial product to profit from the subsequent reaction in a different but related product. In this paper, we develop a simple model that researchers and regulators can use to scan for the susceptibility of two markets to such misconduct. We also test the model empirically on a set of government bond futures contracts using a complete EUREX ultra-high-frequency dataset. Our findings show that cross-product manipulation is feasible across bond futures with different underlying maturities, issuers and contract expiry dates. The results suggest that cross-product manipulation might be widespread despite an increasing crackdown by regulators and prosecutors. •Develop a model to scan for the risk of cross-product manipulation.•Test the model on EUREX government bond futures contracts.•Document the feasibility of cross-product manipulation.•Feasibility across bond futures with different maturities, issuers and expiry dates.
