Concept
A limit is a pre-transaction control on future transaction capability. It is not an accounting transaction, but it affects whether later transactions pass, how much can pass, and whether extra authorization or workflow is needed.

System allowed range >= current effective limit >= actual transaction amount.If the transaction amount exceeds the current limit, the system may reject the transaction, show an over-limit message, or trigger higher authorization depending on transaction type, channel rules, product parameters, and risk policy.

Risk Controls
- Raising limits increases exposure to fraud, mistaken transfers, and loss.
- Lowering limits may block normal customer activity.
- Customer-level and account-level limits must not be mixed.
- Currency, scope, current value, and requested value must be read together.
- Limit maintenance should preserve operator, authorizer, before/after values, timestamp, and business basis.
