A trading halt on SGX does not, by itself, end a stock loan. The facility continues while the shares are not trading, and its documents set how a halted or suspended share is valued and how long a stoppage can last before it becomes an event of default or leads to a call for more collateral or part repayment.
Key takeaways
- A halt is short by design. SGX's practice notes describe a trading halt as a short-term stoppage requested by the issuer to disclose material information; a suspension is generally longer and can also be imposed by SGX.
- The rules govern trading, not your loan. SGX's halt and suspension rules do not mention loans or collateral; the facility documents decide what a stoppage means for yours.
- Valuation during a stoppage is contractual. With no new traded price, the documents say how the charged shares are valued in the meantime, and terms vary by facility.
- A set period, then consequences. The documents set how long a stoppage can last before it becomes an event of default or prompts a call for more collateral or part repayment.
- Options depend on the documents and the lender. Adding collateral, a partial repayment, an agreed standstill or refinancing may be open, but none is guaranteed.
Under SGX's practice notes, a halt or suspension "can be applied at any time", and an issuer's request for one is announced on SGXNet. This note explains how the Listing Rules treat halts and suspensions of Mainboard and Catalist shares, and how a share-backed facility generally responds. It reflects the rules as they stand in October 2026 and is general information, not legal advice.
What is the difference between a halt and a suspension on SGX?
A trading halt is a short-term trading stoppage that an issuer requests in order to disclose material information, and it cannot run beyond 3 market days save for a short extension agreed by SGX. A suspension is generally a longer-term stoppage, which the issuer can request or SGX can impose.
Mainboard Rule 1302 allows SGX (the Exchange, in the rulebook's wording) to grant a trading halt "to enable the issuer to disclose material information", or to suspend trading, at the issuer's request, and SGX "is not required to act on the request". A halt "cannot exceed 3 market days or such short extension as the Exchange agrees", and "may be changed to a suspension by the Exchange at any time".
SGX's Practice Note 13.1 on trading halts and suspensions adds that a halt is "generally requested for a minimum of 30 minutes to a maximum of three market days". During a halt, orders already in the system are not purged until the end of the market day; when a suspension begins, all orders are purged.
SGX may also suspend trading without a request. Rule 1303, in Chapter 13 of the Mainboard Rules, lists the circumstances, including: less than 10% of the issued shares (excluding treasury shares) in public hands; an issuer unable to continue as a going concern, or to show that it can; a contravention of a listing rule; and where SGX considers a suspension necessary or expedient for a fair, orderly and transparent market.
Chapter 13 of the Catalist Rules numbers its halt and suspension rules the same way (Rules 1302 to 1304) and sets the same limit on a halt's length, with sponsor provisions added. SGX normally acts on a halt or suspension request made by the issuer, not the sponsor, and an issuer without a sponsor can be suspended. Catalist Practice Note 13A describes halts and suspensions in the same terms as Practice Note 13.1.
| Point | Trading halt | Suspension |
|---|---|---|
| Who requests or imposes it | The issuer requests it, to disclose material information. SGX may grant it and "is not required to act on the request". On Catalist, SGX normally acts on the issuer's request, not the sponsor's. | The issuer may request one (a voluntary suspension), or SGX may impose one in the circumstances in Rule 1303 (on Catalist, including where the issuer has no sponsor). SGX may also change a halt into a suspension at any time. |
| Usual length | "Generally requested for a minimum of 30 minutes to a maximum of three market days", and it "cannot exceed 3 market days or such short extension as the Exchange agrees". Before trading resumes, the request for lifting must be announced, with at least 15 minutes' dissemination time. | No usual length or maximum is set: a suspension is "generally a longer term trading stoppage". Before trading resumes, the request for resumption must be announced, with at least 30 minutes' dissemination time. After a going-concern suspension, resumption proposals are due within 12 months of the date of suspension. |

How is a halted share valued?
In a stock loan, a halted or suspended share is valued as the facility documents provide, not under SGX rules. With no trades matched during the stoppage, documents usually provide a fallback: the last available price, a value set by the lender or its agent, or a reduced value.
SGX's rules govern trading, not collateral values. Practice Note 13.1 describes both a halt and a suspension as a "trading stoppage", so no new traded price forms until trading resumes. What the facility does with the last price before the stoppage is a matter of drafting, and terms vary by facility.
Some documents keep using the last price for a set period. Others let the lender, or a valuation agent, determine a value, apply a discount to the last price, or treat the shares as having no collateral value while the stoppage lasts. A lower value raises the loan-to-value ratio at once, even though no trade has taken place.
Because a halt exists to let material information reach the market, the first trades after it is lifted can be at a markedly different price. If the value the facility then uses pushes the loan-to-value ratio past the agreed level, the usual margin call mechanics apply: a demand for additional collateral or a partial repayment.
When does a halt become a default?
A halt becomes a default only if the facility documents make it one. SGX's halt and suspension rules govern trading, not loans. The documents typically set how long a stoppage in the charged shares can last before it becomes an event of default or prompts a call for more collateral.
Documents can respond to a stoppage in two ways, sometimes both. A halt or suspension that lasts beyond a period set in the facility agreement can be an event of default, entitling the lender to accelerate the loan and, if it is not repaid, enforce the share charge. Or the stoppage can change how the shares are valued, so that a call for more collateral or part repayment follows.
That period is a negotiated term, separate from SGX's own limits on a halt. Documents may treat a halt and a suspension alike or differently, and a halt that SGX changes into a suspension can move from one category to the other. Documents may also give a cure period, time to put matters right, for example by meeting a call for more collateral.
Other clauses can apply at the same time. Under Rule 1303, a suspension can follow a court application to place the issuer under judicial management or for its liquidation. Facility documents may treat events of that kind, or the issuer's removal from the Official List, as defaults in their own right, and a cross-default clause can carry a default under another obligation into the stock loan.
If the share charge is enforced and the shares realise less than the debt, whether you owe the difference depends on the recourse profile of the facility. A suspended share cannot be sold through SGX's order book until trading resumes, so a long stoppage also affects how and when the collateral can be realised.
What can I do if my shares are suspended?
If shares charged under a stock loan are suspended, read the facility documents, speak to the lender early and take legal advice. Depending on the documents and the lender, options may include adding collateral, a partial repayment, an agreed standstill or refinancing. None is guaranteed.
Start with what the documents say: what counts as a stoppage, the period and any cure period that apply, how the shares are valued in the meantime, and whether you must notify the lender. The loan keeps running during a suspension, so any interest payments and the maturity date still fall due unless the documents say otherwise; our note on tenor, interest and servicing explains how those terms are set.
Options that may be open
- Adding collateral. Further listed shares or cash can restore cover if the lender accepts them, and any new shares raise the same questions of stock loan eligibility as at the outset.
- Partial repayment. Paying down part of the loan lowers the loan-to-value ratio without adding assets to the charge.
- An agreed standstill. A lender may agree not to enforce for a period, on terms, while the issuer works towards resumption.
- Refinancing. Another lender may refinance the facility, but it will assess the suspended share afresh, and a share that is not trading is harder to value.
Follow the issuer's announcements on SGXNet. Practice Note 13.1 expects a suspended issuer to give half-yearly updates, except where suspended under Rule 1303(2) or (3). An issuer suspended on going-concern grounds under Rule 1303(3) must, under Rule 1304, submit resumption proposals (on Catalist, through its sponsor) within 12 months of the date of suspension and implement them within 6 months of SGX indicating no objection, failing which SGX may remove it from the Official List.
Which route is open depends on the documents, the lender and the reason for the suspension. This note is general information, not legal advice: confirm your rights and obligations under the facility with your own Singapore counsel before you act.
