• T+1 Settlement Cycle: From 27 January 2023, all equities on NSE moved to a T+1 rolling settlement cycle, reducing the time between trade execution and settlement from T+2 to T+1. This faster settlement reduces risk of non-payment/delivery and improves liquidity. 
• Digital & Market Infrastructure Reforms: In its July 2024 report, NSE noted that “Indian capital markets: transformative shifts achieved … including ASBA for secondary market, T+1 settlement, shorter MF redemption, faster IPO listing” could yield about INR 3,900 crore efficiency savings.

• Global Rankings: According to a 2023 futures industry review, the NSE Group processed over 84.8 billion contracts, ranking it #1 globally in derivatives by volume.
• Cybersecurity and Infrastructure: NSE faces significant cybersecurity challenges, with reports of up to 170 million daily cyber-attacks targeting it in late 2025, prompting continuous investment in cybersecurity and digital resilience. This underscores the importance of robust tech infrastructure. 

National Stock Exchange Challenges

Despite of various advancements and development, NSE faces several backlashes, criticism and challenges for the following reasons:

• Market Competition & Evolution: With rising fintech platforms, alternative trading venues and global competition, NSE must continuously innovate to retain leadership.
• Cybersecurity & Technological Risks: The magnitude of cyber-attacks (about 170 million daily) highlights vulnerabilities in critical infrastructure. Ensuring uninterrupted service and data safety remains a key priority. 
• Market Volatility & Systemic Risk: High volumes in derivatives markets make exchanges vulnerable to systemic risk. For instance, after a regulatory suspension of a major trading firm, derivative volumes slumped ~17% on NSE. 
• Regulation & Transparency Issues: The NSE has faced scrutiny over co-location facilities and algorithmic trading, which raise concerns of fair access. 
• Inclusion & Access: Despite high volumes, investor participation remains uneven across socio-economic strata and regions. Ensuring financial literacy, regional access and inclusion remains a challenge.

Way Forward:

• Strengthening Technology & Resilience: Invest further in cybersecurity, cloud infrastructure and real-time monitoring to counter attacks and operational risk.
• Enhancing Market Access & Inclusion: Expand investor education via NSE Academy, targeted programmes for Tier-II and Tier-III regions, and mobile/internet trading access.
• Diversifying Products & Services: Expand green-finance products, ESG-linked derivatives, digital assets, and platform for start-ups & SMEs.
• Promoting Settlement Efficiency: Moving towards optional T+0 settlement for certain securities, which would further speed up transactions.
• Regulatory & Transparency Reforms: Clearer guidelines for co-location, fair access to algorithmic trading, and ensuring equitable opportunities for smaller brokers.
• Regional Integration & Globalization: Collaborate with IFSC-GIFT City and other global exchanges to integrate Indian capital markets with global capital flows.
• Sustainable Growth Focus: Position India’s capital markets to handle increasing volumes while maintaining integrity, to support the vision of India as a $10 trillion economy.
