Married Deal: The Pre-Arranged SGX Trade That Lets Two Investors Transact at a Price Outside the Live Order Book
A married deal is a pre-arranged trade on SGX where a buyer and seller agree the price and quantity of shares privately before submitting the order, allowing the transaction to be matched directly rather than through the normal open order book, typically used for large blocks or related-party transfers.

Key Takeaways
- A married deal is a pre-negotiated trade where both the buyer and seller are already known and agreed before the order hits SGX’s trading system.
- Married deals are commonly used for large block transfers, related-party share transfers, or situations where both counterparties want price certainty without moving the live market.
- Unlike a normal order book trade, a married deal’s price can sit outside the current best bid-ask spread, within SGX’s permitted price variation limits.
- SGX requires married deals to be reported and are subject to specific rules on timing and price bands to prevent abuse or unfair pricing.
- Retail investors rarely initiate married deals directly — they are mostly used by institutional investors, corporate insiders, or brokers facilitating large negotiated transfers.
What Is Married Deal?
In a normal SGX trade, a buy order and a sell order are matched anonymously through the exchange’s central order book — the system pairs the best available bid with the best available offer, and neither party necessarily knows who is on the other side. A married deal flips this: the buyer and seller have already agreed privately on the price, quantity, and counterparty before the trade is submitted to SGX, and the trade is essentially “pre-matched.”
The term comes from the two parties being effectively “married” to each other for that specific transaction — there’s no price discovery happening on the exchange itself; SGX’s system is simply used as the official settlement and reporting mechanism for a deal that was struck off-exchange or through direct broker negotiation.
Married deals are distinct from the anonymous continuous trading that dominates most retail activity. They typically involve brokers acting for both sides, or in some cases a single broker representing both the buyer and seller (with appropriate disclosure and compliance checks).
How Does Married Deal Work in Singapore?
On SGX, a married deal must be executed within specific price bands relative to the prevailing market price to prevent abusive off-market pricing — a deal struck wildly outside the current bid-ask range would raise red flags and could be rejected or flagged by SGX’s surveillance systems.
The brokers involved input the agreed price and quantity into SGX’s trading system as a married deal order type, and because both sides are already determined, the trade executes essentially instantly without competing against other market participants for the fill.
Common real-world uses include: a company director transferring a large personal shareholding to a family member or related entity, two institutional funds agreeing to swap a large block without moving the live price by dumping it on the open market, or a controlling shareholder restructuring holdings between related corporate vehicles. These transactions still show up in SGX’s trade reporting and, where relevant, trigger disclosure obligations (such as substantial shareholder notifications) just like any other trade.
Married Deal Example
Suppose a company’s founder-chairman wants to transfer 2 million shares, worth roughly SGD 4 million at current prices, to a family trust as part of succession planning. Dumping 2 million shares into the open market order book could crater the share price temporarily due to the sudden supply, hurting both the chairman (who still holds the bulk of his stake) and other shareholders.
Instead, the chairman’s broker and the family trust’s broker agree privately on a price close to the last traded price, then execute the 2 million shares as a single married deal. The transaction settles through SGX/CDP exactly like any other trade, and is reported, but it never had to compete for liquidity against the live order book — avoiding the price impact a block of that size would normally cause.
Advantages of Married Deal
No market impact. Large transfers can be executed without moving the live share price, protecting both the transacting parties and uninvolved shareholders from artificial volatility.
Price certainty for both sides. Because the price is agreed beforehand, neither party is exposed to slippage from partial fills or a moving order book.
Efficient for related-party and succession transfers. Family office restructuring, corporate reorganisations, and insider transfers can be executed cleanly through this mechanism.
Still exchange-reported and regulated. Unlike a purely private off-market transfer, a married deal still runs through SGX’s official trade reporting and settlement infrastructure, preserving transparency for regulatory and disclosure purposes.
Settlement via CDP as normal. Shares transferred via a married deal settle through the standard CDP system, so ownership records update exactly like any other trade.
Risks and Limitations
Not accessible to typical retail investors. Married deals require broker facilitation on both sides and are generally used for institutional, corporate, or very large transactions — they are not a trading tool available through a normal retail brokerage order ticket.
Potential for related-party pricing concerns. Because the price is privately negotiated rather than market-discovered, there’s always scrutiny around whether the agreed price was genuinely fair, particularly for related-party transactions.
Limited transparency on negotiation. Minority shareholders only see the resulting trade report, not the negotiation process behind a married deal, which can raise governance questions in sensitive situations.
Price band restrictions still apply. A married deal cannot be struck at an arbitrary price — SGX imposes limits relative to the prevailing market price, which can constrain genuinely desired off-market pricing in some cases.
Disclosure obligations still trigger. Substantial shareholder and director’s interest disclosure rules still apply to shares moved via a married deal, so parties cannot use this mechanism to avoid standard transparency requirements.
Married Deal vs Block Trade vs Normal Order Book Trade
| Feature | Married Deal | Block Trade | Normal Order Book Trade |
|---|---|---|---|
| Counterparty known beforehand | Yes, pre-agreed | Often, via broker facilitation | No, anonymous matching |
| Price determined by | Private negotiation (within bands) | Negotiated, often near market | Live order book |
| Typical user | Institutional/related-party/insiders | Institutional investors | All investors including retail |
| Market impact | Minimal | Minimal to low | Can move price if large |
| Settlement | Standard CDP settlement | Standard CDP settlement | Standard CDP settlement |

The Bottom Line
A married deal is a pre-arranged SGX trade mechanism that lets large or related-party share transfers happen cleanly, without disrupting the live market. Retail investors will almost never initiate one directly, but understanding the mechanism explains why some large shareholding changes appear in trade reports without any visible price disruption on the chart.
Frequently Asked Questions
Can retail investors execute a married deal on SGX?
Not in the typical sense. Married deals are generally facilitated by brokers for institutional investors, corporate insiders, or related-party transfers, and are not available as a standard retail order type.
Does a married deal have to happen at the current market price?
Not exactly — the price is privately negotiated beforehand, but SGX imposes permitted price variation bands relative to the prevailing market price to prevent abusive off-market pricing.
Why would a company insider use a married deal instead of selling on the open market?
To avoid moving the share price through sudden large supply hitting the order book, which can hurt both the seller (if the price craters mid-sale) and other shareholders who didn’t ask for the volatility.
Do married deals still show up in substantial shareholder disclosures?
Yes. Standard disclosure obligations around substantial shareholdings and director’s interests still apply to shares transferred via a married deal, just as they would for any other trade type.
Is a married deal the same as a block trade?
They’re related but not identical. A block trade generally refers to a large transaction negotiated near market price, while a married deal specifically means both the buyer and seller were pre-agreed before the order was submitted to the exchange.
