Private and Public Banks: Their Role in Trading

1. Understanding Private and Public Banks
1.1 Public Banks

Definition: Banks owned or majorly controlled by governments.

Examples: State Bank of India (SBI), Bank of Baroda, Punjab National Bank, and international giants like China Development Bank or Germany’s KfW.

Role: Support trade finance, infrastructure, and developmental goals while also operating commercially.

1.2 Private Banks

Examples: HDFC Bank, ICICI Bank, Axis Bank, JPMorgan Chase, Goldman Sachs, HSBC (though HSBC has mixed ownership).

Role: More aggressive in expanding into global markets, offering innovative trading products, and catering to high-net-worth individuals and corporates.

2. Banking as a Foundation for Trading

Both types of banks serve as pillars of the trading ecosystem. Their activities include:

Providing Liquidity: Banks buy and sell financial instruments, ensuring markets don’t dry up.

Market Making: Many large banks act as intermediaries in forex and derivatives trading.

Credit Access: Traders and corporations rely on bank credit to fund positions.

Clearing & Settlement: Banks ensure smooth processing of trades through clearinghouses.

Risk Management: Offering hedging tools, swaps, options, and forward contracts.

7. Challenges Faced by Public and Private Banks in Trading
7.1 Public Banks

Slower adoption of new technologies.

Higher burden of non-performing assets (NPAs).

7.2 Private Banks

Higher exposure to speculative risks.

Vulnerable to global financial shocks (e.g., Lehman Brothers collapse).

Criticism for prioritizing profit over public interest.

8. The Changing Landscape: Fintech and Digital Trading

Both public and private banks are facing disruption from fintechs:

Digital trading apps (Zerodha, Robinhood, Groww) are reducing dependency on banks for stock trading.

Still, banks remain indispensable for clearing, settlement, large-scale financing, and providing credibility.

Public banks are slowly catching up with digitization, while private banks continue to push boundaries with AI-driven trading systems.

Conclusion

The roles of public and private banks in trading are complementary rather than competitive. Public banks provide stability, credibility, and developmental support, while private banks bring innovation, speed, and global connectivity. Together, they form the backbone of the international trading ecosystem.

As trading becomes more globalized, technology-driven, and interconnected, both public and private banks will need to adapt rapidly. The future will likely see a hybrid financial system where state-backed security and private sector innovation coexist to shape the world of trading.
