The Effect of Ship Owner-Ship Operator Separation on the Market Risk Split

Purpose - There are three different business models in shipping: owner-operators, operators, and owners. This paper analyzes the effect of separating owner-operators into tonnage providers and operators, and considers this effect from the perspective of risks and returns. Design/Methodology/Approach - A historical simulation was performed to measure realized operating profits and the volatility of each type of player. Time series data from 1992 was adopted from Clarkson Research and Drewry Maritime Research to simulate revenues, capital costs, and operating costs for 229 investment cases. A bootstrap sampling enhances the robustness of the results. Findings - The results show that the operating profits of owner-operators are divided into those of two separate players. The same, however, cannot be said for market risk. Against general expectations, operator market risk was not significantly reduced by separation; in the case of Panamax, it even increased. This can be explained by a negative correlation between spot rates and actually-applied time charter rates. Research Implication - Most papers on market risk have so far focused on the measurement and forecast of return volatility. This paper, on the other hand, is a novel attempt to analyze the effect of business model separation on market risk. The public-sector owner model is widely discussed in Korean shipping circles, and this paper is expected to provide meaningful insight to policymakers. Additionally, the risk-return profile of the pure owner model provides a good basis to develop the model for the balanced growth of the Korean shipping industry.
