What is the Order Matching Mechanism for Block Deal Transactions?
To execute a block deal order, the quantity and price must match the opposite side block deal order. These orders will be matched based on the same quantity and price, with priority given to the order that comes first in time. It will be cancelled if a block deal order is not executed within 90 seconds.
Order Matching:
Case 1: Example:
- A buy block deal order of 500,000 shares at ₹55.50.
- A sell block deal order of 500,000 shares at ₹55.50.
In this case, the buy order will match with the sell order because both the quantity and price are the same.
Case 2: Example:
- Client ABC enters a buy block deal order for 1,000,000 shares at ₹187.
- Client WYZ enters a sell block deal order for 500,000 shares at ₹187.
- Client PQR enters another sell block deal order for 500,000 shares at ₹187.
Here, the buy order will not match with any of the sell orders because the quantities do not match, even though the price is the same.

Risks and Challenges of Block Deals
Though block deals offer advantages, they also have potential pitfalls that demand prudence.
1. Counterparty Risks
Unlike trades on public exchanges, block deals rely on private agreements between specific parties. This introduces counterparty risk – if one institution reneges on the negotiated terms, it can leave the other in the lurch, resulting in major financial disruption. Establishing trust and accountability between counterparties is paramount.
2. Influencing Markets and Investor Sentiment
Despite attempts to keep them confidential, block deals can indirectly influence broader market movements if word gets out. For example, if an asset manager offloads a huge portion of shares in a company via a block deal, it could signal doubts about that company’s prospects.
This could spark retail investors to follow suit and sell shares, thus inadvertently sinking the stock price. Timing and discretion are key to avoiding unintended signalling effects.
3. Liquidity and Price Impact
For thinly traded stocks, absorbing a large block deal could drastically reduce liquidity and lead to volatile price swings. Institutional investors must be judicious when gauging if the market has sufficient liquidity to support the intended block transaction.
In summary, block deals enable large-scale trades but also introduce risks around counterparty commitments, market ripple effects, liquidity concerns, and volatile price impacts. Institutional investors must weigh these hazards against the benefits when considering block deal strategies.
Conclusion: Future of Block Deals in Stock Market Dynamics
Since block deals are the contemporary favorite strategy of high volume traders, in light of institutional investment evolution, block deals will continue to be the driving force behind trading behavior and influence the price of stocks without being too of an inconvenience. The factors supporting this include efficient capital flow, low volatility, and high liquidity.
The trend toward technological integration and cross-border transactions will only increase the complexity of block deals over time, thereby enabling institutions to achieve strategic objectives in tightly regulated and transparent processes.
Block deals help investors better understand a dynamic stock market. They also help financial market professionals and fans who recognize the subtle complexities surrounding block deals understand market behavior and make the right judgments in a sea of uncertainty.
