A hub-and-spoke model organizes a network around one or more central points, called hubs, that connect to outer locations or users, called spokes. Work, goods, or information moving between two spokes may pass through a hub instead of traveling directly. The model can help consolidate activity, but it can also create extra transfers and concentration risk. The term has a separate, specialized meaning in competition law, explained below.
How a hub-and-spoke model works
Picture a wheel: the hub is at the center, and spokes connect it to points around the edge. In a network, the hub collects, transfers, coordinates, or provides specialized services for the connected spokes.
For example, a distribution network might send goods from local collection points to a sorting center, then route them to retailers or other destinations. A shipment between two outer locations may travel through the sorting center rather than taking a direct route. Networks can also be layered: an assessment of Indian food parks describes collection centers feeding primary processing centers, which then connect to a central processing center.

The structure can coordinate services as well as physical flows. In a UK school partnership example, a lead school coordinates activities, hosts events, and provides specialist resources, while participating schools share strategic responsibility. A hub can therefore centralize coordination without holding every decision. UK Department for Education guidance.

Why use a hub-and-spoke network?
- Consolidate flows: A central site can gather goods or requests that would otherwise move through many separate links.
- Share resources: A hub can pool inventory, specialist skills, equipment, or coordination work for multiple spokes.
- Support scale: Concentrating activity may make sorting, processing, or service delivery more efficient when volume and costs justify it.
- Reduce inventory locations: In supply chains, fewer stocking locations can pool demand and potentially reduce inventory needs under uncertainty.
These are possible advantages, not automatic savings. The outcome depends on flow volume, distance, hub capacity, transfer costs, service expectations, and what happens when operations are interrupted. The National Academies discusses the trade-offs of consolidation and network disruption in a supply-chain context. National Academies, supply-chain chapter.
Hub-and-spoke vs. point-to-point
A point-to-point network connects endpoints more directly. It can avoid transfers through a central site and spread operational dependence across locations. A hub-and-spoke network consolidates links or facilities, which may improve pooling and scale but makes the hub more consequential to the wider network.
| Consideration | Hub-and-spoke | Point-to-point |
|---|---|---|
| Routing | Travel between spokes may go through a hub, adding a transfer or detour. | Endpoints can connect directly, avoiding a central transfer. |
| Scale and resources | Consolidation can pool flows, inventory, or specialist capability. | Activity is less centralized; pooling may be harder to achieve. |
| Disruption | A hub outage can affect many connected routes or services. | Disruption may be less concentrated in one location; schedules can be more flexible in some settings. |
| Best fit depends on | Whether pooling and scale benefits outweigh transfer burdens and concentration risk. | Whether direct access, flexibility, and distributed operations matter more than centralized coordination. |
The National Academies uses airline hubs and supply chains to illustrate these trade-offs: disruption at an airline hub can affect a wider domestic network, while point-to-point schedules may be more flexible and reactive. In inventory planning, fewer locations may improve risk pooling, whereas more locations can diversify disruption risk. National Academies, supply-chain chapter.
Advantages and disadvantages to assess
Before choosing a design, compare the network on the factors that matter to the people, goods, or services moving through it:

- Cost and scale: Include facility and operating costs, and test whether consolidated volume actually creates economies of scale.
- Time and convenience: Account for transfers, waiting, detours, and how easily users at the spokes can reach services.
- Resilience: Ask how many routes or services would be affected by a hub outage, and whether backup hubs or alternate routes exist.
- Reach and capacity: Check whether the hub can serve dispersed origins and destinations and handle peak demand.
- Control and responsibility: Establish who sets shared priorities, pays for central functions, and keeps local spokes responsive.
These factors are decision prompts, not a universal scorecard. A centralized design may suit one network and underperform in another; the relevant comparison is between the actual costs, service needs, and failure scenarios of each option.
The competition-law meaning is different
In competition policy, “hub-and-spoke” refers not simply to a centralized network but to a possible route for indirect coordination among competitors. Firms at one level of a supply chain—the spokes—may exchange information or agreements through a common trading partner, such as a manufacturer, retailer, or service provider—the hub. The legal question is whether vertical dealings between each firm and the intermediary amount to horizontal coordination among competitors.
The OECD describes these arrangements as “horizontal restrictions on the supplier or retailer level (the ‘spokes’), which are implemented through vertically related players that serve as a common ‘hub’ (e.g., a common manufacturer, retailer or service provider).” OECD, “Hub-and-Spoke Arrangements in Competition” (2019). The label alone does not prove wrongdoing; assessment depends on the evidence and applicable jurisdiction. For the OECD’s analysis, see its 2019 policy paper.

A hub-and-spoke design deserves particular scrutiny when the central site has limited capacity, transfers add unacceptable delays, spokes need direct links, or a hub failure would interrupt too much of the network. The main safeguards to examine are sufficient capacity, contingency routes, backup hubs, and clear responsibility for central operations. Whether those measures are worthwhile depends on the cost of prevention compared with the likely consequences of interruption.
