Why Branch Networks Still Matter
Although digital banking is growing rapidly, physical branches remain important for:
- Cash deposits and withdrawals
- SME and corporate banking
- Customer support
- Loan processing
- Financial inclusion in underserved communities
Banks with larger branch networks are often better positioned to serve customers nationwide, especially in areas where digital infrastructure is less developed. (Intelpoint)
