Supply chain

A supply chain is the entire network of individuals, organizations, resources, activities, and technologies involved in creating and delivering a product or service.

What it is

A supply chain encompasses all the steps required to bring a product from its raw materials to the final consumer. This includes sourcing materials, manufacturing, packaging, transportation, warehousing, and distribution. Each stage involves various companies and processes, forming a complex global network. For example, a smartphone's supply chain might involve mining rare earth elements in one country, manufacturing components in another, assembling in a third, and selling worldwide.

Supply chain disruptions, such as port congestion, shipping rate increases, or geopolitical events like trade wars, can significantly impact product availability, production costs, and consumer prices. Companies may experience inventory destocking or delays, affecting their profitability and stock performance. Governments monitor supply chains for national security and economic resilience, often encouraging nearshoring or reshoring to reduce reliance on foreign sources, especially for critical goods like rare earth elements or semiconductors.

Why it matters

Supply chain health directly impacts company revenues, product availability, and consumer prices. Disruptions can cause inflation, market volatility, and affect investment returns.
