Netting only applies within the same tenor bucket. A 1M import payable and a 9M export receivable don't offset each other's timing risk — that's not a natural hedge, just two separate exposures that happen to exist. Also worth remembering: most Indian MSMEs convert FCY promptly rather than holding it — FCY balances earn no yield while INR working-capital funding costs are high, so long-dated natural hedging is rarely how this actually plays out in practice.
Not in use — ladder below is driven by the Importer/Exporter toggle above, applied uniformly across all tenors.
