Why should Berkeley pay for a bank that also lends money to Oakland, Richmond, and other cities?

Answer

Berkeley isn't just paying into this bank; Berkeley is becoming an owner of it. A bank makes money by making loans, and the amount it can safely lend is tied directly to the size and diversity of its capital base. A larger, regionally diversified loan portfolio is lower-risk and more profitable than one that only lends in a single city. As an owner, Berkeley shares proportionally in that profit and stability. The long-term goal remains a fully regional bank, co-capitalized by Oakland, Richmond, Alameda County, and other jurisdictions, which would reduce the share Berkeley carries over time.
