What mattered this month

August 2026 centred on UDiFF Catalogue V3.0.1.2: NSDL named the DARPAN ID field (DrpanId), added regulatory-order capture on freeze/unfreeze, BSDA Modification Upload, demise-intimation fields, and revised nomination capture — production EOD 28 August (demise fields BOD 29 August). Both depositories rolled out the SEBI transmission SOP and forms, with NSDL monthly transmission reporting due from September. July KYC/KRA non-compliant accounts face a 5 September freeze.
