“…Because of the interconnected global shipping network, the local shock in China propagated to other regions and became a global shock. Bai et al (2022) use data derived from the Automatic Identification System to quantify the impact of pandemic lockdown policies on global port calls. They find that in February 2020, container shipping at ports with high levels of connectivity to Chinese ports was significantly affected by Chinese lockdown policies, with a time lag of two to three weeks, depending on the voyage duration of a container ship.…”

Forecasting stock returns is challenging. Traditional economic data that are available to all investors are published with lags and suffer from the problem of frequent revisions. Consequently, they often fail to forecast stock returns. For this reason, investors are increasingly interested in seeking alternative data. This paper forecasts stock returns using satellite-based information on shipping containers, which can capture economic activity in real-time. The container coverage area in each port is identified from 83,672 satellite images via the U-Net method and used as a proxy for the number of containers. Forecast combination over univariate predictive regression is used to generate return forecasts. The results indicate that the number of containers in ports can significantly predict stock index returns in 27 out of 33 countries at a daily frequency for the 2019–2021 period. An investor making use of satellite data on marine ports can, on average, receive an annualized return of 16.38%. The predictability can be explained by the predictive relationship between port container numbers and economic activity. In future studies, satellite data can be applied to monitor and forecast other economic indicators.

“…Due to the outbreak, port operations have been affected resulting in extended operation times. In regions with intense quarantine practices, the number of port calls has decreased (Bai et al, 2022). In Türkiye, competent authorities have promptly implemented precautionary policies to mitigate the impacts of Covid-19 outbreak.…”

The Covid-19 outbreak is a recent major crisis with a broad and lasting impact on the economy, health, and society, rather than an immediate and temporary impact. In the first months following the declaration of the pandemic, the container shipping sector in Türkiye was impacted by restrictions and quarantine measures. During this period, there were reductions in ship calls, slowdowns in ship operations, and losses in storage and warehousing services. Although container volumes in Türkiye were less impacted than the global average, the previously stable growth trend came to a halt. This study examines the impact of the Covid-19 outbreak on container shipping in Türkiye as a case study. Relevant literature and statistical data were analyzed to provide a detailed examination of the specific impacts in Türkiye. In addition, the study aims to support national goals and increase resilience to future crises by providing recommendations for the stakeholders and national policy makers. These recommendations include the adoption of digitalization and blockchain technologies, regional expansion of maritime trade, considering storage strategies and developing logistics infrastructure.

“…Maritime networks could be disrupted by unexpected events, such as natural disasters (Breuer et al., 2021; Li et al., 2022), terrorist attacks (Cao & Lam, 2019), dockworker strikes (Thekdi & Santos, 2016) and pandemics (Bai et al., 2022; Guerrero et al., 2022; Hou et al., 2022; Jin et al., 2022). These disruption scenarios are generally divided into two types in existing studies: port closures and link disconnections.…”

Global liner shipping network (GLSN) constitutes an essential part of global maritime supply chains, but it could be vulnerable to disruptions. This paper develops an integrated framework for assessing the efficiency and vulnerability of GLSN. Specifically, a novel efficiency metric is proposed to quantify the performance of GLSN, and the framework enables modeling different levels of port disruption scenarios. Results show that the overall GLSN is quite robust under the partial disruption scenario of any single port (or of any single country's ports), but the damage to different countries is highly heterogeneous. Under dismantling scenarios where the identified most critical ports (countries) are successively disrupted, the GLSN vulnerability increases non‐linearly with an increasing level of disruption. Our findings demonstrate that it is necessary to monitor and protect the identified critical ports (countries); especially, avoiding their simultaneously complete disruptions is of vital importance to the robust functionality of GLSN.
