Empirical Investigation of the Impact of Piracy on Shipping Freight Rates in the Gulf of Guinea

Maritime piracy imposes direct costs on shipping operations through ransom payments, cargo losses, and crew welfare, as well as indirect costs through elevated insurance premiums and freight rate adjustments that reflect the risk environment. This study empirically investigates the impact of piracy incident frequency and severity on shipping freight rates in the Gulf of Guinea region, using an econometric modelling approach. A quantitative research design was adopted, using a panel dataset constructed from quarterly piracy incident data from the International Maritime Bureau piracy reports for the Gulf of Guinea, matched with freight rate index data for the relevant trade routes and supplemented with war risk insurance premium data from leading maritime underwriters. Panel data regression models with vessel type and quarter fixed effects are estimated to identify the relationship between piracy variables and freight rate outcomes. Results confirm a statistically significant positive association between piracy incident frequency and freight rates on Gulf of Guinea routes, with the estimated freight rate premium attributable to piracy ranging from seven to fifteen percent above the baseline for equivalent non-piracy-affected routes. The piracy premium on war risk insurance premiums is identified as a significant transmission mechanism. The study contributes the first econometric estimate of the piracy-freight rate relationship specific to the Gulf of Guinea trade, filling an empirical gap in the maritime security economics literature.
