Abstract

This study analyzed the connectivity of the dry bulk carrier market before and after COVID-19 to examine the impact of COVID-19 on the global shipping market. Using the Quantile Time Frequency Connectedness methodology, we analyzed the dynamic connectedness of major dry bulk indices: the Capesize Index (BCI), Supramax Index (BSI), Panamax Index (BPI), and Handysize Index (BHSI). The results are as follows. First, the total spillover connectedness of the dry bulk carrier market increased during the entire period and in the short term after the outbreak of COVID-19, while it slightly decreased in the long term. Second, the roles among the indices changed according to market conditions, with COVID-19 causing the BPI to change from a net receiver to a net transmitter in the short term and the BSI in the long term, affecting net spillover connectedness. Third, it was observed that long-term connectivity tended to increase more than short-term connectedness under extreme conditions. Fourth, the phenomenon of strengthened connectedness under extreme market conditions was confirmed. These results provide important insights into understanding short-term market shocks and long-term stability trends, demonstrating that the connectedness among dry bulk carrier markets strengthens in global crisis situations such as COVID-19. This provides a basis for assessing the resilience and vulnerability of the shipping market and offers useful information for investors and policymakers in crisis management and investment strategy formulation.

본 연구는 COVID-19 이전과 이후의 건화물선 시장 연계성을 분석하여, COVID-19가 글로벌 해운 산업에 미친 영향을 살펴보았다. 주요 건화물선 시장 운임 지수인 케이프 지수(BCI), 수프라막스 지수(BSI), 파나막스 지수(BPI), 핸디사이즈 지수(BHSI)의 동적 연계성을 Quantile Time Frequency Connectedness 방법론을 사용하여 분석하였다. 분석 결과는 다음과 같다. 첫째, COVID-19 발생 이후 건화물선 시장의 총 전이 연계성은 전체 기간과 단기적으로 증가한 반면, 장기적으로는 약간 감소하였다. 둘째, 지수 간의 역할이 시장 상황에 따라 변화하였으며, COVID-19로 인해 단기 BPI와 장기 BSI가 순 수신자에서 순 전달자로 변하는 등 순 전이 연계성에 영향을 미쳤다. 셋째, 극단적인 상황에서 장기 연계성이 단기보다 더 증가하는 경향이 관찰되었다. 넷째, 극단적인 시장 상황에서 상호 연계성이 더욱 강화되는 현상을 확인할 수 있었다. 이러한 결과는 단기적인 시장 충격과 장기적인 안정성 추세를 이해하는 데 중요한 시사점을 제공하며, COVID-19와 같은 글로벌 위기 상황에서 건화물선 시장 간의 연계성이 강화됨을 보여준다. 이는 해운 시장의 복원력과 취약성을 평가할 수 있는 근거를 마련하고, 투자자와 정책 결정자에게 위기 관리와 투자 전략 수립에 유용한 정보를 제공한다.
