Logistics Terms What Are the Differences? Spot Rates vs Contract Rates

Spot Rates vs Contract Rates at a Glance

Since the onset of COVID-19, there has been a shift in the logistics industry and the behaviors of exporters. Spot rates increased dramatically in the months following the outbreak and were extremely volatile for some time afterward. This had a significant impact on shippers' spending and made it difficult to predict supply chain, transportation, and inventory planning. As the global uncertainty and geopolitical tensions persist, exporters, trade organizations, transportation companies, governments, and others are closely watching how freight rates are changing.

Logistics freight rates can generally be divided into spot rates and contract rates. In practice, shippers rarely operate their entire freight volume on spot rates or contract rates alone, and usually use a mix of both. Understanding when to use one or the other is essential to keeping supply chain costs low. In this article, we will take a look at what spot and contract freight rates are, how they differ and correlate, and which one is more favorable depending on the situation.

Sopt Rates

Definition

Spot rates are one-time charges that apply to specific ocean or air transportation that have not been arranged in advance. The rates are affected by a number of variables, including local demand, oil prices, bunker (marine fuel) prices, and are determined by capacity. Since spot rates are only valid for a single transaction, they carry inherent risk and can be highly volatile depending on the market conditions. In particular, recent military conflicts in the Red Sea region have made it difficult for ships to transit the area, which has led to an increase in spot rates. If this situation continues, global logistics disruptions could occur, which could have a significant impact on the global economy.

Variables

Spot rates can be higher depending on a number of factors:

• 1) Transit time: In case of urgent shipments
• 2) Probability of return: If there is a low probability of securing a return shipment at the destination
• 3) Value of the shipment: In case of expensive, high-value shipments
• 4) Weight of the shipment: In case of heavy shipments
• 5) Transportation requirements: In case of dangerous goods, batteries, etc. that need to be transported by qualified personnel using special equipment

Since spot rates reflect the balance of supply and demand in real time, they tend to increase during periods of high demand and decrease during periods of increased supply.

• - Example 1) COVID-19: As logistics demand surged globally, spot rates increased significantly. This is due to the global supply chain being disrupted by the COVID-19 pandemic, which has caused issues such as ship disruptions.
• - Example 2) Year-end peak season: Spot rates tend to increase at the end of the year, when logistics demand increases globally. This is due to an increase in shipments of gifts and goods ahead of holidays such as Christmas and New Year holidays.
• - Example 3) Post-COVID-19: As the COVID-19 pandemic has eased, global supply chains have recovered and ship operations have resumed, causing spot rates to fall. This is because supply has increased, balancing supply and demand.

Contract Rates

Definition

Contract rates are the costs that have been negotiated with a carrier for a specific period of time, typically one year, but they can also be negotiated for six months, two years, three years, etc. Contract rates are primarily based on factors such as the estimated volume of cargo to be transported, the requirements of the shipment, and recent spot rates. The longer the contract term, the cheaper the rates tend to be.

The advantage of contract rates is that you can make a long-term logistics planning, and a certain amount of space is guaranteed for each week or month. This ensures a stable logistics supply and allows you to predict logistics costs.

Contract rates are mainly used by large exporters and manufacturers, who can negotiate a good deal with the carrier because they are transporting large quantities of goods. The carrier is often willing to negotiate a good deal because they can earn a stable profit by securing large volumes.

Variables

A variety of factors affect the terms of negotiations between shippers and carriers, which contributes to lowering the contract rates in the following cases. Contract rates are necessary to ensure predictability and stability of shipping costs.

• 1) The value of the shipment: If the value of the shipment is low
• 2) Route and frequency of transportation: If the route is the major route serviced by the carrier or has a certain level of frequency that allows the carrier to make a profit
• 3) Volume of cargo: If the cargo is high in volume and a certain quantity is guaranteed
• 4) Regularity of cargo: If the frequency of cargo transportation is constant and the volatility is low

Spot Rates vs Contract Rates

Correlation

There are several correlations between spot and contract rates. When negotiating contract rates, spot rates serve as a baseline for negotiation, along with consideration of future freight rates and market capacity.

In the midst of COVID-19, the global supply chain experienced an enormous scale of supply chain disruptions, as there was simply not enough transportation capacity to meet the surging demand due to congestion in vessel and equipment operations. This resulted in spot rates that were more than 10 times higher than average at the time. Nevertheless, shippers were not guaranteed any vessel space or equipment. At this time, some carriers entered into long-term contracts with shippers at rates lower than spot rates but higher than average contract rates in anticipation of the market stabilization in the near future. Conversely, competition for contract rates has recently intensified, which has led to an increase in spot rates.

As the market cooled, spot rates returned to pre-COVID-19 levels but contract rates remained high, allowing carriers to maintain the lowest rates during the contract term before returning to normal spot rates.

A relevant example is the annual "Trans Pacific" contract signing season. During this season, shippers tend to delay signing contracts in anticipation of further declines in spot rates. This is because the longer they wait, the more likely it is that spot rates will fall further, which puts them in a position to negotiate lower contract rates with carriers.

Recently, spot rates have been rising due to supply chain disruptions like the Red Sea crisis, which can lead to higher contract rates. Since spot rates fluctuate based on short-term supply and demand, when supply chain issues occur, spot rates rise quickly as supply becomes scarce. Contract rates are used for long-term, stable logistics planning, but sometimes carriers will increase contract rates when supply chain issues arise.

Advantages

1) Contract rates

If you have relatively consistent factors in your production process, such as the load amount and timing, contract rates are best suited for you. Contract rates allow you to have a stable logistics operation, which makes planning and budgeting easier. You will be able to collaborate strategically with your carrier, track performance, and quickly turn around issues.

• - Better planning and budgeting
  How can you plan and budget when your freight costs are out of whack? You never know if a big event will happen next week that will cause your freight costs to skyrocket. But with contract rates, you can plan and budget for a stable contract period.
• - Opportunities to work with strategic carriers
  The more a carrier works with a shipper, the stronger the partnership becomes. This can be beneficial for both parties in many cases. For example, shippers can get discounts and send shipments faster without using the spot market. Since both the carrier and shipper already have a productive work history and relationship, they are more likely to be able to solve problems on their own.
• - Increased likelihood of securing capacity
  Not all contracts guarantee capacity, but most do. Even in contracts that don't guarantee capacity, the carrier is likely to be proactive in helping you secure capacity.
• - Easier to track performance
  Having a reliable freight transportation service makes it easier to track business performance. Contract rates stabilize your shipping costs and make it easier to calculate your business performance.
• - Rate Basis
  Contract rates are often negotiated as part of a short-term business model without long-term customer relationships, and are negotiated at a lower cost than spot rates.
• - Freight regularity and seasonality
  Contract rates are best suited for freight that is regular and less subject to seasonal fluctuations.
• - Minimum volume
  In the case of contract rates, shippers agree to a minimum volume of freight to be delivered to a carrier over a period of time.

2) Spot Rates

If your company's operations have a lot of variability in terms of timing, size, and destinations, spot rates may be a better option. Especially if you need to be flexible with the transportation of your products, spot rates may be more expensive in the short term, but in the long run, they can be a more efficient choice.

• - Validity period
  Spot rates are often one-offs and have a very short validity, essentially meaning that you are participating in a spot market.
• - Tactical or strategic
  Spot rates are a tactical approach that relies on short-term commitments and the spot market to secure the best rate now.
• - Specific vs. recurring
  Spot rates are used when you have an unexpected or irregular flow of freight, while contract rates are used when you have a continuous and constant flow of freight for the duration of the contract.
• - Volatility
  Due to the temporary nature of spot rates, they are highly volatile and dependent on a number of factors.
• - Freight regularity and seasonality
  Spot rates are used for cargo that is subject to seasonal fluctuations or specific events.
• - Volume
  For spot rates, the volume of transportation is usually not high, or if it is, it is handled in one go or spread out over a very short period of time.
• - Rate Applicability
  Spot rates are the rates prevailing at that point in time in the market and apply equally to all customers. Shippers who make spot bookings can expect to have fairly uniform rates, with only minor fluctuations based on specific causes.

Frequently Asked Questions

Q1. In which case is contract rates more advantageous?

If you have confidence in freight stability and predictions!

If you have a regular or large volume of freight that will be shipped steadily throughout a year or so, contract rates can be a better choice. Freight contracts allow the shipper or cargo owner to build a long-term relationship with the seller or carrier with outstanding services, which can be a reason to choose contract rates even though spot rates may be cheaper. Contract rates allow the shipper or cargo owner to create a stable logistics plan for the long term. Since a certain amount of space is guaranteed each week or month for the duration of the contract, shippers can predict logistics costs. They can also negotiate better terms with their carrier when making large volume shipments. The advantage of contract rates is that you can reduce your logistics costs and ensure a stable logistics supply.

Q2. In which case is spot rates more advantageous?

If you are unable to plan shipment in advance!

Spot rates are useful for unplanned shipments when contracted carriers are not available, or for routes that are volatile and do not have negotiated contract rates. Spot rates are also useful for short-term logistics planning because they fluctuate based on short-term supply and demand. If you are shipping small volumes, it’s hard to negotiate good terms with carriers. In this situation, spot rates can give you the flexibility to control your logistics costs because they fluctuate based on short-term supply and demand. In particular, spot rates have the advantage of being able to adjust quickly to changing circumstances.

Q3. Would it be possible to apply both spot rates and contract rates?

In most cases, yes!

Depending on the terms of the contract, your relationship with the seller or carrier, the route, and the volume of the shipment, some shipments may be able to be shipped at a spot rate despite having applied the contract rate. Typically, some shipments are operated at spot rates if they are lower than the long-term contract rates. In practice, very few companies operate their entire freight volume on spot rates or contract rates and usually use a mix of both, and it's a good idea to adjust the proportions based on market conditions.

Q4. Can spot and contract rates be used simultaneously?

Yes, most shippers blend both. Core volume goes on contract rates for stability; residual/urgent/irregular volume goes on spot.

Q5. Is the MQC always mandatory in contract rates?

Most contracts include an MQC clause. Non-compliance may incur penalties — commit realistic volumes based on historical performance.

Q6. Which strategy works better during a crisis like the Red Sea situation?

Spot rates surge first, so pre-secured contract space gives an advantage. Pre-negotiation with carriers is key because they might attempt to raise contract rates.

Q7. Can small shippers negotiate contract rates?

When the volume is low, direct bargaining may not be feasible, but you can still gain contract rate advantages indirectly through a forwarder. This is because forwarders aggregate multiple shippers' volumes and negotiate with carrier collectively.

Q8. Can I compare rates and check schedules on Cello Square?

Cello Square provides real-time ocean/air rate checks, schedule search, quote comparison, and booking on a single platform, supporting the establishment of an optimal rates strategy.
