초록

발틱해운거래소는 건화물 해상무역 지수인 BDI(Baltic Dry Index) 지수를 발표하고 있는데, BDI 지수는 철광석, 석탄, 곡물 등 주요 건화물을 운송하는 벌크선박의 평균 용선료를 의미한다.
현재 BDI 산출의 기초가 되는 용선료 데이터는 케이프사이즈 40%, 파나막스 30%, 스프라막스30%의 비중으로 반영되고 있다. 이처럼 케이프사이즈는 건화물 시장을 구성하는 다양한 사이즈의 선박 중에서도 대장 역할을 담당하고 있다.
본 연구는 벡터오차수정모형(Vector Error Correction Model; VECM)을 활용하여 변수 간의 인과관계를 검증하였으며, 이를 통해 케이프사이즈 용선료에 영향을 미치는 변수 간의 장기균형모델을 도출하고자 하였다. 분석결과, 케이프사이즈 선복량 1% 증가시 용선료 0.08% 감소, 엔달러 환율 1% 증가시 0.01% 감소, 세계 GDP 1% 증가시 0.02% 증가, 철광석과 석탄 물동량1% 증가시 각각 0.11%, 0.09% 증가, 벙커유 가격 1% 증가시 0.04% 증가하는 실증분석 결과를계측하였다. 벌크선 중 핸디막스, 파나막스급 활용도가 낮아지고 상대적으로 케이프사이즈의 활용도가 높아지고 있는데 본 연구는 케이프사이즈를 대상으로 하여 분석을 수행하였다는 점에서의의가 있다.

The Baltic Shipping Exchange is reporting the Baltic Dry Index (BDI) which represents the average charter rate for bulk carriers transporting major cargoes such as iron ore, coal, grain, and so on. And the current BDI index is reflected in the proportion of capesize 40%, panamax 30% and spramax 30%. Like mentioned above, the capesize plays a major role among the various sizes of bulk carriers and this study is to analyze the influence of the factors influencing on charter rate of capesize carriers which transport iron ore and coal as the major cargoes. For this purpose, this study verified causality between variables using Vector Error Correction Model (VECM) and tried to derive a long-run equilibrium model between the dependent variable and independent variables. Regression analysis showed that every six independent variable has a significant effect on the capesize charter rate, even at the 1% level of significance. Charter rate decreases by 0.08% when capesize total fleet increases by 1%, charter rate increases by 0.04% when bunker oil price increases by 1%, and charter rate decreases by 0.01% when Yen/Dollar rate increases by 1%. And charter rate increases by 0.02% when global GDP increases by one unit (1%). In addition, the increase in cargo volume of iron ore and coal which are major transportation items of capesize carriers has also been shown to increase charter rates. Charter rate increases by 0.11% in case of 1% increase in iron ore cargo volume, and 0.09% in case of 1% increase in coal cargo volume.
Although there have been some studies to analyze the influence of factors affecting the charterage of bulk carriers in the past, there have been few studies on the analysis of specific size vessels. At present moment when ship size is getting bigger, this study carried out research on capesize vessels, which are biggest among bulk carriers, and whose utilization is continuously increasing. This study is also expected to contribute to the establishment of trade policies for specific cargoes such as iron ore and coal.
