Examine the governance challenges faced by market infrastructure institutions (MIIs) in ensuring fair and equal access to trading systems in India.

Market infrastructure institutions — stock exchanges, clearing corporations and depositories — are commercial entities discharging a quasi-public, self-regulatory function. The SECC Regulations, 2018 require them to serve the market in the public interest [1], yet the NSE co-location episode shows that equal access to trading systems remains a live governance problem.

Technology-driven inequality of access

• Latency advantage: co-location servers and point-to-point dark fibre connectivity give select algorithmic and high-frequency traders speed edges invisible to ordinary investors.
• SEBI's settlement order on NSE's Trading Access Point (TAP) architecture and network connectivity confirms that access design itself, not just conduct, is a regulatory concern [2].
• Rapid technological change outpaces rulemaking; SEBI's 2025 framework on safer participation of retail investors in algorithmic trading is a corrective response [3].

Conflict of interest in the MII model

• Revenue depends on high-volume institutional members, while the same institution must police them — a for-profit versus self-regulator tension.
• Listing ambitions sharpen this: NSE's long-pending IPO stayed blocked until regulatory matters were closed [4].

Weak internal controls and accountability

• Preferential connectivity was routed through an unauthorised service provider, indicating failures of internal audit, board oversight and public-interest-director scrutiny [4].
• Whistleblower complaints, not internal systems, first surfaced the lapses.

Delayed and negotiated enforcement

• Proceedings ran over a decade before resolution through SEBI's consent/settlement route under the Settlement Proceedings Regulations, 2018 — efficient, but without admission of guilt, weakening deterrence [5].
• NSE finally paid ₹1,491.21 crore in settlement of the co-location and dark fibre matters [4].

Fair access is ultimately a question of institutional design, not merely penalties. Strengthening independent oversight boards, mandating periodic technology and access audits, publishing latency and connectivity data, and setting time-bound adjudication would align MIIs with their public-utility character. Read with SEBI's algo-trading reforms, such measures advance the SEBI Act's mandate of investor protection and orderly market development.
