The World Container Index (WCI) is a weekly benchmark that tracks spot container freight rates on major global east-west trade routes. Published by Drewry, the index provides a useful reference for shippers, importers, exporters, freight forwarders and supply chain professionals monitoring changes in ocean freight costs.
Understanding the WCI can help businesses compare market trends, review shipping budgets and make better-informed decisions about international freight forwarding services.
What is the World Container Index (WCI)?
The World Container Index (WCI) is a comprehensive container freight index jointly launched by Drewry, a globally renowned maritime research and consulting firm, and the Singapore Cleartrade Exchange. The WCI is one of the most influential freight benchmarks in the international shipping market and is widely used in index-linked contracts and market analysis.
- Route Coverage: The WCI tracks spot market freight rates on 8 major global trade routes, including key lanes such as Shanghai to Rotterdam, Shanghai to Genoa, Shanghai to Los Angeles, and Shanghai to New York, connecting the three major markets of the United States, Europe, and Asia.
- Calculation Method: It comprehensively considers spot freight rates and various surcharges, providing a weighted average composite rate per 40-foot container (FEU) .
- Publication Frequency: Released every Thursday, providing timely updates on the latest market dynamics.
How Is the WCI Calculated?
The WCI is based on assessed spot market freight rates for major container shipping routes. It is presented as a weighted composite rate per 40-foot container.
The index is useful because it brings together rate information from several important trade lanes rather than focusing on one port pair only.
The WCI generally includes routes such as:
- Shanghai to Rotterdam;
- Rotterdam to Shanghai;
- Shanghai to Genoa;
- Genoa to Shanghai;
- Shanghai to Los Angeles;
- Los Angeles to Shanghai;
- Shanghai to New York;
- New York to Rotterdam.
The exact route composition, methodology and rate components may be updated by the index provider. Businesses should refer to the latest methodology before using the WCI for contracts, budgeting or formal benchmarking.
How Often Is the WCI Published?
The WCI is generally published weekly, providing a regular view of changes in spot container freight rates.
A weekly index can help businesses monitor:
- Rate increases and decreases;
- Changes on the Asia-Europe trade;
- Changes on the transpacific trade;
- Seasonal demand;
- Port congestion;
- Capacity constraints;
- Blank sailings;
- Changes in carrier surcharges;
- Effects of geopolitical or weather-related disruption.
The WCI is most useful when reviewed over time. A single weekly movement may not represent a long-term market trend.
What Does the WCI Rate Mean?
A WCI rate is normally expressed in US dollars per 40-foot container.
For example, if the composite WCI is quoted at a particular amount per FEU, this indicates the assessed average spot rate across the index’s selected routes. It does not mean that every route has the same price.
Rates on individual routes may differ significantly because of:
- Port pair;
- Equipment availability;
- Cargo volume;
- Transit time;
- Vessel capacity;
- Market demand;
- Port congestion;
- Fuel costs;
- Carrier pricing;
- Seasonal conditions.
Businesses should compare the relevant route-specific rate rather than relying only on the composite index.
Other Common Freight Indices
The industry also features other important freight indices, each covering different routes and offering unique perspectives on the market.
Shanghai Containerized Freight Index (SCFI)
The Shanghai Containerized Freight Index (SCFI) is compiled and published by the Shanghai Shipping Exchange. It focuses on spot market freight rates for exports from the port of Shanghai, China, to major regions worldwide, including Europe, the Mediterranean, Southeast Asia, and South Korea.
The SCFI reflects the spot market freight levels for exports from Shanghai. It is known for being sensitive and timely, making it suitable for industry players who need to monitor short-term market fluctuations.
Freightos Baltic Index (FBX)
The Freightos Baltic Index (FBX) is used to record changes in current container freight rates on global routes. It sources data through the Freightos platform. The FBX tracks container freight rates on 12 major global trade routes and provides a composite index.
WCI, SCFI and FBX: What Is the Difference?
| Index | Main coverage | Best used for |
|---|---|---|
| WCI | Major global east-west trade lanes | Monitoring broad global container freight trends |
| SCFI | Exports from Shanghai | Reviewing Shanghai-origin spot freight rates |
| FBX | Major global container trade lanes | Comparing route-specific container pricing |
These indices are not interchangeable. Each one uses its own route coverage, data sources and methodology.
Why Is the WCI Important?
1. Supports Freight Cost Planning
The WCI gives businesses a market reference when reviewing ocean freight budgets and comparing changes over time.
It can help importers and exporters identify whether a carrier quotation is broadly in line with current spot market conditions. However, it should not replace a shipment-specific quotation.
2. Helps Identify Market Trends
By tracking WCI movements over several weeks or months, businesses can identify wider market patterns, such as:
- Rising demand;
- Reduced vessel capacity;
- Seasonal peaks;
- Port congestion;
- Trade route disruption;
- Falling or increasing spot rates.
This information can support decisions about shipment timing, inventory planning and contract negotiations.
3. Supports Supply Chain Decisions
A significant change in container freight rates may affect the choice between ocean freight, air freight and other transport options. For urgent or high-value cargo, businesses may need to consider air freight solutions alongside ocean freight.
4. Helps Compare Route and Carrier Options
The WCI can provide a general reference when businesses compare different routes or carrier quotations. The final decision should also consider transit time, reliability, available equipment, service frequency and destination handling.
5. Improves Landed-Cost Visibility
Freight rates are only one component of total logistics cost. Businesses should combine the WCI with origin transport, customs, handling, warehousing and final-delivery costs. Warehousing and distribution services may also affect the total cost of moving goods from supplier to customer.
Limitations of the WCI
The WCI is a useful market benchmark, but it does not provide a complete quote for every shipment.
The final price may vary depending on:
- Exact origin and destination;
- Container size and equipment type;
- Cargo type;
- Shipping date;
- Booking conditions;
- Contract or spot rate;
- Carrier;
- Port and terminal charges;
- Customs requirements;
- Inland transportation;
- Surcharges;
- Special handling requirements.
The WCI also focuses on selected routes and may not represent smaller regional lanes or specialised services.
Businesses should use the WCI together with current carrier quotations and professional logistics advice. For further logistics information, visit the U-Freight resources centre.
How Can Businesses Use the WCI?
Businesses can use the WCI in the following ways:
- Monitor weekly movements in container freight rates.
- Compare the relevant route with the composite market trend.
- Review the difference between spot rates and contract rates.
- Assess whether ocean freight remains suitable for the shipment.
- Include current market conditions in inventory planning.
- Review whether early booking may reduce capacity or delay risks.
- Compare freight rates with the total landed cost.
- Discuss route, timing and service options with a freight forwarder.
The WCI should be one source of information within a broader logistics decision-making process.
