Supplier bargaining power tends to be weaker when?

Supplier bargaining power tends to be weaker when good substitute inputs exist because the availability of alternatives reduces the leverage that suppliers have over buyers. When a company can easily switch to other suppliers or find substitute goods, it diminishes the supplier's ability to dictate terms or raise prices. This competition encourages more favorable terms for the buyer.

In contrast, when suppliers furnish critical components, when it is costly to switch suppliers, or when there is a low availability of substitute inputs, the suppliers are in a stronger position. In these scenarios, buyers are typically more dependent on the suppliers, which enhances the suppliers' bargaining power. Thus, having good substitute inputs is a key factor that weakens supplier bargaining power.
