First Hawaiian Bank is the largest bank in the state and the oldest, tracing back to 1858. Its main branch anchors the Bishop Street financial district in downtown Honolulu, with branches across Oahu, Maui, Kauai, and the Big Island, plus Guam and Saipan. The bank covers consumer checking and savings, commercial lending, mortgages, merchant services, trusts, insurance, and auto financing. For Hawaii businesses, the practical advantage is an underwriting team that already understands leasehold property, GET obligations, and island valuation quirks that routinely confuse mainland lenders.
