Warehousing norms revised: enhanced accreditation, financial security and inspection standards to secure good delivery in commodity derivatives markets. SEBI prescribes minimum exchange-level standards to ensure guarantee for settlement of trades including good delivery by accrediting WSPs, warehouses and assayers through transparent selection and renewal; imposing paid-up capital and net worth criteria, refundable security deposits and tiered Financial Security Deposits with prescribed asset forms and concentration limits; mandating insurance on replacement value; requiring SOPs, KYD, PAN disclosures, staff training and prohibition on trading by WSP management; and establishing periodic independent inspections, audit disclosure, cancellation and continuity procedures.
