NSE (National Stock Exchange) and BSE (Bombay Stock Exchange) are India's two major stock exchanges where Sovereign Gold Bonds are traded in the secondary market.

NSE: - India's largest exchange by trading volume - SGBs listed under "Others" or "SGB" segment - Trading hours: 9:15 AM - 3:30 PM (Monday-Friday) - Symbol example: SGBJAN24

BSE: - Asia's oldest stock exchange - Also lists all SGB series - Same trading hours as NSE - May have different liquidity for some SGBs

For SGB trading: - Both exchanges list same SGB series - Prices may differ slightly (arbitrage opportunity) - Choose based on liquidity (usually NSE has higher) - Order execution is similar on both
