For investors venturing into the Indian stock market, the banking sector holds undeniable allure. But when it comes to choosing the right banking index fund, confusion can arise between two prominent options: Bank Nifty and Bankex. This blog sheds light on the key differences between these indices, equipping you to make informed investment decisions.

What are stock market indices?

Stock market indices are statistical representations of a specific section of the market. They track the performance of a basket of stocks by calculating an average based on their market capitalization (total market value). The stock market indices serve as valuable benchmarks for investors to gauge the overall health and performance of a particular sector.

What is Bankex?

The Bankex, or S&P BSE Bankex, is a stock market index maintained by the Bombay Stock Exchange (BSE). It tracks the performance of the 10 largest and most liquid banking stocks listed on the BSE. Here's a breakdown of Bankex's key characteristics:

  • Wider Coverage: Bankex encompasses a broader universe of banking stocks compared to Nifty Bank. This provides a more diverse representation of the Indian banking sector.
  • Free-Float Market Capitalisation: Bankex considers the free-float market capitalization of each constituent stock, which refers to the portion of shares readily available for trading in the public market.

What is Nifty Bank?

The Nifty Bank is a stock market index maintained by the National Stock Exchange of India (NSE). It focuses on the top 12 most liquid and valuable banking stocks listed on the NSE. Let's delve into the defining features of Nifty Bank:

  • Narrower Focus: Nifty Bank tracks a smaller number of banking stocks compared to Bankex, primarily focusing on the largest players in the sector.
  • Full Market Capitalization: Nifty Bank considers the full market capitalization of each constituent stock, including both freely tradable shares and those held by promoters or institutions.

Nifty Bank vs Bankex: which is the right one for you?

The ideal choice between Bankex and Nifty Bank depends on your investment goals and risk tolerance:

  • Bankex: A good option for investors seeking a more diversified exposure to the Indian banking sector, including both large and mid-sized banks. This might offer a slightly lower risk profile due to its broader representation.
  • Nifty Bank: A suitable choice for investors who want to focus on the performance of the leading players in the Indian banking space. This might offer the potential for higher returns but also carries a slightly higher risk profile due to its narrower focus.

Additional factors to consider

  • Tracking Error: Both Bankex and Nifty Bank index funds aim to replicate the performance of their respective indices. However, a slight tracking error might exist, meaning the fund's returns might deviate marginally from the index's performance.
  • Expense Ratio: Compare the expense ratios of different Bankex and Nifty Bank index funds. This fee covers the cost of managing the fund and should be factored into your overall return calculations.


Understanding the distinctions between Bankex and Nifty Bank empowers you to make informed stock investment decisions. Consider your investment goals, risk tolerance, and the specific characteristics of each index before choosing the one that best aligns with your investment strategy. Remember, diversification is key, and incorporating both banking sector indices into your portfolio might be a well-rounded approach for some investors.
