Abstract

The capital structure of the shipping business, which is characterized by its capital intensity and extreme market volatility, is closely related to long-term stability. Research in this area has been conducted mostly in the form of deriving the determinants of capital structure from company-wise financial ratios. This research, on the other hand, has a different approach to the topic. It identifies the relationship between actual cash profit and loss and other variables - i.e. actual vessel prices, interest rates and leverage ratio - by employing historical simulation. The result demonstrates that the P anamax cash profit shows 0 (break-even point) when the debt weight reaches 64.38% (debt ratio 180.74%) and the Cape, 73.04% (debt ratio 270.92%). Additionally, the ships of different types show a divided pattern for the pre- and post-'Super Boom'. It indicates that the business area and the market cycle should be considered when a leverage strategy is established. This research benefits shipping companies set a rational leverage strategy as well as delivers a reasonable guideline to government authorities for the development of a sound policy on shipping finance.

해운업은 선박투자에 대규모의 자본이 소요되는 한편 시장의 변동성이 극심하기 때문에 투자자금의 조달구조는 기업의 안정성과 직결된다. 지금까지의 해운업 자본구조 연구는 주로 재무제표를 기반으로 자본구조의 결정요인을 도출하는 형태로 진행되었지만 이 연구에서는 접근을 달리하여 과거의 선박가격, 이자율 그리고 부채비중의 변화가 실제 어느 정도의 현금손익으로 이어졌는지 역사적 시뮬레이션을 통해 파악하였다. 연구 결과 현금손익이 0이 되는 손익분기점이 파나막스선은 부채비중 64.38%(부채비율 180.74%), 케이프선은 73.04%(부채비율 270.92%)인 것으로 나타났는데 이는 케이프선에서 추가적인 부채 활용이 가능함을 의미한다. 또한 'Super Boom' 이전과 이후로 구분하여 분석한 결과 선종별로 다른 패턴이 형성되었다. 이를 통해 선종 즉, 영업영역별로 다른 레버리지의 관리가 필요하며 시황 국면에 따라서도 탄력적인 관리가 필요하다는 시사점을 찾을 수 있었다. 이 연구는 해운기업의 입장에서는 기업의 장기적인 안정성을 확보하는 자금조달 구조파악 측면에서, 그리고 해운과 선박금융 정책을 입안하는 정책당국의 입장에서는 해운산업의 건전성을 견인하는 측면에서 실무적인 기여를 할 것으로 기대된다.
