The short version: open banking lets a company reach its customers' bank accounts (or its own, across many banks) through one API, instead of building a separate integration with every bank — and in the EU, PSD2 requires banks to expose those interfaces, so the rails are regulated rather than a favor a vendor can withdraw. Practically, that means finance teams can pull real transaction data instead of chasing CSV exports and PDF statements, and product teams can ship bank-connected features (account verification, onboarding, payment initiation) without becoming licensed financial institutions themselves. Cost is the third angle: connectivity pricing ranges from free low-volume tiers to per-connection or per-call fees, and the difference compounds quickly at scale. I maintain open-banking.io, an independent site about bank-data APIs, and the way I'd frame it for a company is: open banking turns bank connectivity from a months-long project into a utility — the real decision is choosing a provider whose bank coverage and reliability match where your users actually hold accounts.
