Supply Chains: Why Disruptions Ripple Through the Economy

Modern supply chains are global and efficient, but also vulnerable to disruption.

By Felix Narayan | Oct 22, 2026 | 4 min

A supply chain includes all the steps involved in producing and delivering a product, from raw materials to the consumer.

Global supply chains allow specialisation and lower costs, but disruptions can spread widely.

I Why supply chains became global

Lower transport costs and trade liberalisation allowed firms to source inputs worldwide.

II Just-in-time

Many firms keep low inventories to reduce costs. This increases efficiency but reduces resilience.

III Disruptions

— Natural disasters
— Pandemics
— Shipping bottlenecks
— Geopolitical tensions

IV Effects

Disruptions can cause shortages, price increases, and delays.

V Building resilience

Firms may diversify suppliers, hold more inventory, or move production closer to home.
