The port of the rotary tiller is the bottleneck of supply, which is a reflection of the problems of the US supply chain. The reasons for the port problems include: surge in demand, labor shortages and lack of transportation equipment. The problem of labor shortage and lack of equipment is unlikely to improve in the short term, and supply chain recovery and capacity improvement can only wait for demand to fall. The magnitude and speed of the drop in demand determines the pace of improvement in supply.
The supply recovery process will be very slow. According to estimates, it is estimated that the handling of port problems will require at least half a year. Since the epidemic, container freight rates have continued to rise. As of the beginning of January 2022, the SCFI composite index has increased by nearly 400% compared with the beginning of 2020. From In terms of the rising tempo, the increase in freight rates can be divided into two stages. The first stage is a single rising market dominated by the Asia-North America route.
The second stage is the general increase in global freight rates. The general rise began at the end of 2020, and the single market switched to the global general. Various signs indicate that container demand has peaked, but supply bottlenecks continue to disturb the changes in freight rates. How much space for incremental supply, how to improve bottlenecks and how freight rates will be interpreted in the future are the key points of this analysis. This paper is mainly divided into three parts: the composition of container capacity is complex, which will be presented first from the capacity structure, the factors affecting the capacity will be dismantled, and the elastic space of supply will be discussed; and solutions; the third part will separate the changes in the supply and demand structure.
