What is "market foreclosure"

n. (context economics English) The use or result of commercial practices by one market participant or a group of market participants (possibly with governmental assistance) that limit the access of buyers and sellers to each other.

Market foreclosure is the exclusion that results when a downstream buyer is denied access to an upstream supplier (caused from an Upstream foreclosure) or when an upstream supplier is denied access to a downstream buyer. A supplier or intermediary in a supply chain can acquire this form of market power through mergers and acquisitions up and down its value chain ( vertical integration).
