In Porter’s Five Forces, which condition indicates strong supplier power?

• A. Suppliers can command a price premium because there are no easy substitutes, a diverse customer base, an important need for your product, and credible forward integration risk.
• B. Buyers have low negotiating power due to few substitutes.
• C. The industry has easy entry for new players.
• D. There is a credible threat of backward integration by buyers.

Answer: (A)

The main idea here is that supplier power is strong when suppliers can push costs up because their inputs are essential, there are few substitutes, and they have credible ways to exert leverage over buyers. When an input is indispensable to buyers’ operations and substitutes are scarce, buyers become heavily dependent on the supplier. Add in a credible threat of forward integration by the supplier—where the supplier could start producing the buyer’s product themselves—and the supplier gains even more bargaining power. The fact that the supplier can command a price premium confirms this leverage in practice.

So this option captures the key signals of strong supplier power: no easy substitutes, the input is critically needed, and a credible forward integration risk that supports higher pricing. The other choices describe situations that either shift power toward buyers or indicate easier entry or rivalry, which don’t reflect strong supplier power.
