Sea freight container rates are one of the important costs in international trade, and their price fluctuations directly affect the logistics costs and supply chain efficiency of enterprises. Understanding the factors that affect shipping container freight rates will not only help enterprises formulate more reasonable logistics budgets, but also help them gain an advantage in market competition. This article will analyze in detail the ten key factors affecting shipping container freight rates and explore the logic and trends behind them.

Fuel price fluctuations
Fuel prices are one of the most direct factors affecting shipping container freight rates. Fuel costs account for a considerable proportion of the operating costs of ships. When international oil prices rise, shipping companies usually pass on costs by levying a fuel surcharge (BAF), resulting in higher freight rates.
In recent years, international oil prices have been affected by multiple factors such as geopolitics, supply and demand, and environmental policies, and have fluctuated frequently. For example, the Russian-Ukrainian conflict in 2022 caused oil prices to soar, directly pushing up global shipping costs. In addition, with increasingly stringent environmental regulations, the use of low-sulfur fuel has also increased the operating costs of shipping companies.
By 2025, fuel prices may stabilize with the advancement of renewable energy technology and environmental policies, but their impact on ocean freight rates cannot be ignored.
Changes in Supply and Demand of Containers
The supply and demand relationship in the shipping market is the core factor that determines freight rates. When the demand for cargo transportation is greater than the supply of ship capacity, freight rates tend to rise; conversely, freight rates fall.
In recent years, the growth of global trade volume and the expansion of ship capacity have not always been synchronized. For example, in the early days of the COVID-19 pandemic in 2020, global trade volume plummeted, resulting in a sharp drop in freight rates; after the economic recovery in 2021, demand surged, coupled with port congestion and supply chain disruptions, freight rates rose rapidly again.
In the next few years, with the recovery of the global economy and the rise of emerging markets, the demand for shipping is expected to continue to grow. However, the investment of shipping companies in new ships and the elimination of old ships will also affect the supply of capacity, and changes in the supply and demand relationship will continue to dominate the trend of freight rates.
Port congestion and efficiency
The operating efficiency of a port directly affects the turnover speed and transportation costs of ships. When ports are congested, ships wait longer and shipping companies have to incur additional costs, which are ultimately passed on to freight rates.
In recent years, major ports around the world have generally faced congestion problems, especially during the pandemic, when labor shortages and epidemic prevention measures have exacerbated port operating pressures. For example, congestion at the Ports of Los Angeles and Long Beach has caused ships to wait for weeks, pushing up trans-Pacific freight rates.
By 2025, with the popularization of port automation technology and the upgrading of infrastructure, port efficiency is expected to improve, but the growth of global trade volume may still pose challenges to port operating capabilities.
Geopolitical Risks
Geopolitical risks are one of the unpredictable factors that affect shipping container freight rates. Events such as wars, sanctions, and trade barriers may lead to route disruptions, increased insurance premiums, or higher transportation costs.
For example, the 2022 Russian-Ukrainian conflict led to the disruption of Black Sea routes, and some goods had to be transported via detours, increasing transportation time and costs. In addition, trade frictions between China and the USA have also led to capacity constraints on some routes, pushing up freight rates.
In the coming years, the global geopolitical situation will remain full of uncertainty, and companies need to pay close attention to related risks and develop flexible logistics strategies to cope with possible freight rate fluctuations.
Shipping Peak Season
Like many industries today, shipping season can be considered the peak time of the year when ocean freight rates are greatly affected. This is because during these times, demand for ocean freight is higher, which affects vessel capacity, global supply chains, and ultimately shipping prices.
The main peak season usually starts in July and lasts until November/December as businesses start to stock up for the holiday rush. Shipping lines raise their prices, saying it is peak season. Shipping lines may impose peak season surcharges to compensate for the extra logistical effort that businesses have to put in due to the sudden increase in passenger traffic.
At the same time, ocean freight rates are not only affected by demand, but also by regional events. For example, around the Lunar New Year in January/February and during the National Day Golden Week in the first week of October, production activities in China virtually came to a standstill, bringing global supply chains to a standstill.
The rush to get goods out before the holidays leads to higher demand and higher container shipping prices.
Exchange Rate Fluctuations
The impact of exchange rate fluctuations on ocean freight rates is mainly reflected in two aspects: first, the operating costs of shipping companies are usually denominated in US dollars. When the local currency depreciates, shipping companies may increase freight rates to make up for the costs; second, exchange rate fluctuations will affect the purchasing power and pricing strategies of import and export companies, thereby indirectly affecting freight demand.
For example, the strengthening of the US dollar in 2020 led to higher import costs in many emerging market countries, which suppressed freight demand; while the depreciation of the US dollar in 2021 stimulated the recovery of global trade and pushed up freight rates.
In the next few years, as the global economic landscape changes, exchange rate fluctuations will continue to be one of the important factors affecting ocean freight rates.
Emergency Bunker Surcharge (EBS)
EBS stands for Emergency Bunker Surcharge, which is an emergency charge that shipping lines charge shippers when fuel prices start to rise (i.e. at the last minute). The higher the fuel price, the higher the EBS charge, calculated by the rate of increase in fuel costs. The main difference from BAF is that EBS is implemented without warning; hence the word “emergency”. Shipping lines may apply EBS arbitrarily, and shippers are usually frustrated by the move because it masks factors that are beyond their control.
The cost of EBS can be based on issues related to ocean freight rates. Some of these issues include the type of cargo, carrier, container type, and nature of cargo (dry or refrigerated cargo). For example, in shipping from China to UAE, the EBS charge for a 20-foot container is $50 to $60, while the EBS charge for a 40-foot container is $90 to $180. Shipping companies have been quick to announce additional EBS costs due to rising fuel prices, the upcoming new low-sulfur emission standards, and falling spot prices.
Vessel Capacity Supply
The supply of vessel capacity directly affects the competitive landscape and freight rates in the shipping market. When the delivery of new ships is greater than the elimination of old ships, excess capacity may lead to a drop in freight rates; conversely, tight capacity may push up freight rates.
In recent years, shipping companies have invested in building larger and more energy-efficient ships in response to environmental regulations and market demand. However, the long delivery cycle of new ships may lead to insufficient capacity in the short term.
By 2025, with the delivery of new ships, the supply of capacity is expected to be balanced, but the capacity management strategy of shipping companies will still be a key factor affecting freight rates.
Cargo Types and Transportation Requirements
Different types of cargo have different requirements for transportation conditions and services, which affect freight rates. For example, dangerous goods, refrigerated goods, and oversized equipment usually require special transportation equipment and operating procedures, resulting in higher freight rates.
In addition, the timeliness of cargo transportation also affects freight rates. For example, the demand for fast transportation of e-commerce goods usually requires priority space and fast loading and unloading services, which will increase transportation costs.
In the next few years, with the rapid growth of cross-border e-commerce and high value-added goods, the demand for efficient and customized transportation services will further increase, thereby pushing up freight rates on related routes.

Market Competition Pattern
The competitive pattern of the shipping market directly affects the level of freight rates. When the market concentration is high, it is easier for shipping companies to control freight rates through coordinated pricing; when the market competition is fierce, freight rates may fall.
In recent years, the global shipping market has undergone multiple integrations, and major shipping companies have formed an oligopolistic competition pattern through mergers and acquisitions and alliances. For example, the 2M Alliance, Ocean Alliance, and THE Alliance control most of the global shipping capacity and have a strong say in freight pricing.
By 2025, with the entry of emerging shipping companies and the rise of digital platforms, the market competition pattern may change, which will have a new impact on freight rates.
Incoterms for Shipping
Incoterms specify who is responsible for shipping, the seller or the buyer, at certain stages of the shipping process. Common Incoterms for container freight are:
- Ex Works (EXW): When the buyer places an order, the seller only provides the goods and packs them. The buyer is responsible for the rest of the process, such as loading the goods onto the ship and clearing customs.
- Free on Board (FOB): The seller is responsible for loading the goods onto the shipping vessel and bears all costs.
- CIF (cost, insurance and freight) Incoterms: The seller pays for freight and insurance and delivers the goods to the port of delivery.
- Delivered Duty Paid (DDP): The buyer specifies a location, and all responsibilities and risks are borne by the seller until the goods arrive at that location.
