Banks in many countries require customers to maintain a minimum average balance (MAB) in savings accounts. If the balance falls below this threshold, banks charge a penalty.
In India, these rules are regulated under the framework of Reserve Bank of India guidelines, which allow banks to set minimum balance requirements depending on account type and location (metro, urban, rural).
As a result:
• Customers with low balances frequently incur penalties.
• Small account holders may lose a significant portion of their savings due to charges.
• Banks collectively earn substantial revenue from minimum balance penalties.
• Financial inclusion efforts may be weakened because low-income users avoid maintaining bank accounts.
This creates inefficiencies at scale:
• Financial burden on economically vulnerable customers
• Reduced trust in the banking system
• Discouragement of small savings behavior
• Increased account dormancy or closure
In a financial inclusion ecosystem, minimum balance penalties can disproportionately affect those with the least financial flexibility.
Proposed Solution
Introduce an Optional Non-Withdrawable Balance System for Low-Balance Accounts.
The concept:
Instead of charging a penalty when balance falls below the minimum threshold, banks could allow customers to designate a portion of funds as non-withdrawable reserve balance.
Example:
Account balance: ₹5,000
Customer marks ₹2,000 as reserve balance
Available withdrawable balance: ₹3,000
As long as the reserve portion remains untouched, no penalty is charged.
How the System Would Work
1️⃣ Customer Choice
When opening or managing a savings account, customers could choose between:
Option A – Traditional minimum balance rule
Option B – Reserve balance lock
2️⃣ Non-Withdrawable Reserve
Customers can lock a small amount (e.g., ₹1,000–₹3,000).
This balance:
• cannot be withdrawn unless the lock is removed
• satisfies minimum balance requirement
• protects customers from penalties
3️⃣ Digital Controls
Bank apps could include:
Toggle reserve balance
Adjust reserve amount
Emergency unlock option
Benefits
• Protects low-income customers from penalties
• Encourages savings discipline
• Improves trust in banking institutions
• Supports financial inclusion goals
Strategic Opportunity
Regulators such as the Reserve Bank of India could encourage banks to offer flexible minimum balance alternatives for small savers.
With digital banking infrastructure already in place, implementing such a feature would require minimal technical changes while delivering significant social impact.
