銀行 can refer to any financial institution, not just commercial banks.
銀行 specifically refers to a bank, while 金融機関 (kin'yū kikan) is a broader term for financial institutions including banks, credit unions, and insurance companies.
Always use the correct particle with 銀行. For example, 銀行に (to the bank) or 銀行で (at the bank).
From 銀 (gin, 'silver') + 行 (kō, 'institution' or 'to go'). The term reflects the historical use of silver as currency in banking transactions.
銀行 is a formal term. In casual conversation, people may use 銀行 (ginkō) or simply 銀 (gin) as shorthand in context.
