If you’ve ever received a freight quote one week and found the price has changed the next, you’re not alone.
Freight rates are constantly moving in response to global supply chain conditions. While these fluctuations can sometimes seem unpredictable, there are several key factors that consistently influence the cost of moving goods around the world.
Understanding what drives freight rates can help businesses plan ahead, reduce surprises, and make more informed supply chain decisions.
Demand
One of the biggest factors affecting freight rates is demand. When more businesses are looking to move cargo, competition for available space increases. As vessels, aircraft, trucks, and rail services fill up, carriers often raise rates to reflect the higher demand.
Demand can increase for a variety of reasons, including:
- Peak retail seasons such as Christmas
- Businesses building inventory ahead of major sales periods
- Manufacturers increasing production
- Importers bringing shipments forward ahead of new tariffs or regulations
A good example is when businesses rush to import stock before proposed tariff increases or trade policy changes take effect. This sudden surge in bookings can quickly drive rates upwards.
Capacity
Capacity refers to the amount of space available to move cargo. Even when demand remains relatively stable, rates can rise if available capacity falls.
Capacity can be reduced due to:
- Cancelled vessel departures (known as blank sailings)
- Aircraft shortages
- Port omissions
- Equipment shortages
- Adverse weather conditions
- Vessel diversions caused by global events
Shipping lines regularly adjust capacity to balance market conditions. For example, carriers may cancel sailings during quieter periods to prevent vessels operating with excess space. While this helps carriers manage costs, it can also reduce available capacity and increase freight rates for shippers. Simply put, when space becomes scarce, prices tend to rise.
Fuel Costs
Fuel is one of the largest operating expenses across all modes of transport. When oil and fuel prices increase, carriers often introduce or adjust fuel-related surcharges to recover these additional costs.
These may include:
- Bunker Adjustment Factors (BAF) in ocean freight
- Fuel surcharges in air freight
- Fuel escalation charges in road transport
Global oil markets can be influenced by geopolitical tensions, production cuts, refinery disruptions, and economic conditions, all of which can have a direct impact on freight costs.
A recent example was the conflict between the United States and Iran, which created uncertainty around the Strait of Hormuz, one of the world’s most important shipping routes. Concerns that oil flows through the region could be disrupted caused energy markets to react, pushing fuel prices higher.
As fuel costs increase, carriers often pass these additional expenses on through fuel surcharges, ultimately affecting freight rates. While recent developments suggest tensions may be easing and normal shipping activity could resume, global energy markets remain highly sensitive to events in the region.
Congestion
Congestion occurs when ports, airports, terminals, or transport networks become overwhelmed.
This can result in:
- Vessel queues
- Delayed departures and arrivals
- Increased storage costs
- Equipment shortages
- Reduced schedule reliability
Congestion doesn’t just affect one location. Delays at a major port can have knock-on effects throughout global shipping networks, reducing available capacity and pushing rates higher elsewhere.
Recent years have demonstrated how quickly congestion can spread across supply chains, creating disruption far beyond the original bottleneck.
Global Events and Geopolitical Disruption
In today’s interconnected world, global events can have a significant impact on freight rates.
Examples include:
- Regional conflicts
- Trade disputes and tariff changes
- Canal or waterway disruptions
- Industrial action and strikes
- Regulatory changes affecting international trade
The events of 2026 highlighted just how quickly freight markets can react to geopolitical developments. The conflict involving Iran and concerns surrounding the Strait of Hormuz affected oil prices, shipping schedules, insurance costs, and overall supply chain confidence worldwide. Even when cargo continues to move, uncertainty can create additional costs throughout the supply chain.
Another recent example has been disruption to shipping routes in the Red Sea region. Many carriers diverted vessels around the Cape of Good Hope rather than transiting through the Suez Canal. Although services continued operating, the longer journeys increased transit times and effectively reduced vessel capacity, contributing to higher freight rates on many trade lanes.
Equipment Availability
Freight rates are also influenced by the availability of equipment, particularly shipping containers.
When containers become concentrated in one region and are unavailable in another, carriers may struggle to meet demand.
This can lead to:
- Equipment imbalance surcharges
- Delays securing containers
- Reduced flexibility when booking shipments
- Increased transport costs
Container availability became a major issue during the pandemic and remains an important factor in certain markets today.
Seasonal Events That Affect Freight Rates
Certain annual events regularly influence freight markets and can often be planned for in advance.
Chinese New Year
Chinese New Year is one of the most significant events in global manufacturing.
Many factories across China close for one to three weeks, and businesses often rush to ship goods before production stops. This surge in demand can place pressure on available capacity and drive rates higher in the weeks leading up to the holiday.
Following the celebrations, rates may fluctuate again as production resumes and backlogs are cleared.
Golden Week
Golden Week takes place in China from 1st to 7th October each year.
During this period, manufacturing and logistics activity slows significantly. Shipping lines often respond by reducing capacity through blank sailings.
Businesses frequently try to move cargo before the holiday begins, creating increased demand and potential rate increases in the weeks beforehand.
Christmas Peak Season
The run-up to Christmas remains one of the busiest periods for global supply chains.
Retailers import large volumes of stock to meet consumer demand, particularly for consumer goods, electronics, toys, and seasonal products.
This increased demand can affect both sea freight and air freight rates.
Why Freight Rates Can Change Quickly
Freight markets rarely move because of a single factor. A combination of strong demand, reduced capacity, rising fuel costs, congestion, and global events can create significant changes in rates over a relatively short period.
Likewise, when market conditions improve, rates can fall just as quickly. This is why freight pricing is often described as dynamic and why businesses benefit from keeping a close eye on market developments.
How Businesses Can Manage Freight Cost Volatility
While no business can control global freight markets, there are practical steps that can help minimise the impact of fluctuating shipping costs:
- Plan shipments as early as possible
- Book ahead of known peak seasons such as Chinese New Year and Golden Week
- Maintain flexibility around shipping dates where practical
- Consider alternative transport modes or routes
- Monitor market developments and regulatory changes
- Work with an experienced freight forwarding partner who can provide guidance on current market conditions
Early planning often provides the greatest opportunity to avoid delays and secure more competitive freight rates.
