A floating charge lets your company keep trading with its stock, receivables and cash as if they were unencumbered. That freedom ends when the charge crystallises. From that moment, the charge fixes onto whatever assets the company then has in the charged class, and the company’s licence to deal with them in the ordinary course of business stops. Directors who do not realise this has happened can keep paying suppliers, selling stock or moving money in a way that conflicts with the lender’s security.

This article explains what crystallisation is, the events that cause it under Singapore law, how automatic crystallisation clauses work, and what directors should do when a crystallising event is close. It is part of our series on company charges, which begins with how fixed and floating charges differ.
What crystallisation means
The Court of Appeal in Malayan Banking Bhd v Bakri Navigation Co Ltd [2020] SGCA 41 described a floating charge as security for the lender coupled with a “business dealing licence” for the company. Crystallisation is the point at which that licence ends. The charge stops floating over a changing pool and attaches, as an equitable fixed charge, to the specific assets in the charged class at that time.
In practical terms, after crystallisation:
- the company can no longer sell or dispose of the charged assets in the ordinary course of business without the lender’s consent;
- assets the company acquires afterwards are usually still caught, if the charge covers future assets;
- the lender can take steps to enforce, typically by appointing a receiver, as explained in our guide to receivership in Singapore; and
- competing claims, such as those of a later lender, a buyer of the assets or an unsecured creditor trying to enforce a judgment, may be affected by whether crystallisation happened before or after their interest arose.
Crystallisation does not change the charge’s treatment in a liquidation. Preferential creditors still rank ahead of it under IRDA s 203(6), because that rule applies to a charge that was floating “as created”. We explain this in our article on what a floating charge holder actually recovers.
The events that crystallise a floating charge
The Court of Appeal in Malayan Banking grouped crystallising events into three categories.
| Category | Examples | Why it crystallises the charge |
|---|---|---|
| Cessation of trading as a going concern (“as a matter of law”) | A winding up order or resolution; the company in fact stops trading; the company disposes of substantially its whole undertaking with a view to stopping business | The reason for allowing the company to deal with its assets disappears once it is no longer a going concern, so the law implies that the charge crystallises |
| Intervention by the lender | Appointment of a receiver or manager under the debenture; the lender taking possession of the charged assets | The company is deprived of control over its assets |
| Events specified in the debenture | Written notice from the lender converting the charge; automatic crystallisation clauses triggered by events such as creating other security or a creditor levying execution | The parties have agreed when the licence ends |
Crystallisation as a matter of law has a high threshold
In Malayan Banking, the bank argued that a Malaysian shipbuilder’s dealings with a vessel outside the ordinary course of its business had crystallised the bank’s floating charge. The Court of Appeal rejected the argument. It held that crystallisation by operation of law occurs when the company ceases to trade as a going concern, either through winding up or de facto cessation of trading, and that a transaction that is merely unusual or outside the ordinary course of business does not crystallise the charge as a matter of law. The court described the threshold as a high one.
For directors, the point is reassuring but limited. An unusual sale or financing does not automatically crystallise the bank’s floating charge. But it may still breach the debenture’s covenants, it may trigger a contractual crystallisation clause, and the buyer may not take free of the charge if the transaction falls outside what the charge allows.
The ordinary course of business test
Whether a dealing is within the ordinary course of business also matters for priority between the lender and a third party who deals with the company. The Court of Appeal, following its earlier decision in Diablo Fortune Inc v Duncan, Cameron Lindsay [2018] 2 SLR 129, applied a two-stage test from the English case Ashborder BV v Green Gas Power Ltd:
- would an objective observer with knowledge of the company view the transaction as having taken place in the ordinary course of its business; and
- on the proper interpretation of the charge, did the parties nonetheless intend that such a transaction should not be treated as in the ordinary course of business?
The fact that a transaction is unprecedented, exceptional, or even in breach of a director’s duty does not necessarily take it outside the ordinary course of business. But transactions intended to bring the business to an end, or that have that effect, are not in the ordinary course.
Automatic crystallisation clauses
Most bank debentures contain a clause stating that the floating charge will crystallise automatically, without notice, if certain events occur. Common triggers include:
- the company creating or attempting to create other security over the charged assets without consent;
- a creditor levying distress, execution or attachment against any of the charged assets;
- a winding up application being filed or a meeting being called to consider a winding up resolution;
- an application for judicial management or a moratorium; and
- the company ceasing, or threatening to cease, to carry on business.
Singapore courts have applied clauses of this kind according to their wording, although the Court of Appeal has not had to rule squarely on their validity. In practice, the lender must show that the event described in the clause actually occurred. In Malayan Banking, the debenture provided for automatic crystallisation if the company “encumbered” charged property in favour of a third party, and defined “encumbrance” widely, including a “sale with right of retention”. The bank argued that the shipbuilder’s transfer of title in a vessel to a buyer, while keeping the vessel in its yard, was such an encumbrance. The High Court and the Court of Appeal disagreed: there was no evidence the shipbuilder had any legal right to retain the vessel, so the clause was not triggered, and the charge crystallised only later, when the bank served written notice.
Two practical points follow. First, the exact wording matters: a lender who relies on an automatic clause needs to show the trigger event actually happened as described. Second, automatic crystallisation can happen without anyone noticing. Directors may find out only later that the company’s dealings after the trigger were with assets that had already become subject to a fixed security.
Crystallisation by notice
Most debentures also allow the lender to crystallise the charge by written notice, usually after an event of default or when the lender considers the assets to be in jeopardy. This is the most common route in practice and the one that fixes the date most clearly. Notice is often served together with, or shortly before, a demand for repayment or the appointment of a receiver.
Who is affected by crystallisation
| Person | Position after crystallisation |
|---|---|
| The company and its directors | Can no longer deal with charged assets in the ordinary course without consent. Continuing to do so risks breaching the debenture and exposing directors to criticism if the company later fails |
| A buyer of charged assets | May take subject to the charge if the sale happened after crystallisation, particularly if the buyer had notice of it |
| A judgment creditor enforcing against the assets | Generally ranks behind the crystallised charge unless the execution was completed before crystallisation |
| A later secured lender | Priority depends on the terms of the charges, notice and registration; our guide to priority disputes between registered charges explains the rules |
| Employees and other preferential creditors | Still rank ahead of the charge in a liquidation or receivership under IRDA s 203(6) and s 86 |
What directors should do when a crystallising event is close
- Read the debenture’s crystallisation clause. Identify every automatic trigger and every event that allows the lender to serve notice. Check whether filing a winding up application, an execution by a supplier or a new hire purchase arrangement could trigger it.
- Keep a record of dates. If a trigger event has occurred, note the date and how the board learned of it. Disputes about crystallisation are usually disputes about timing.
- Talk to the lender before major transactions. A sale of significant assets, a sale and leaseback or new financing should be cleared with the lender in writing. Do not assume a transaction is safe because the floating charge has not been mentioned.
- Consider the company’s solvency. Crystallising events often arise when a company is in difficulty. Directors’ duties shift towards creditors as insolvency approaches. Our guide to a bank recalling a company loan covers the options, including standstill and restructuring.
- Check the ACRA register. Confirm that the charge was registered on time, as a charge that was not registered is void against the liquidator and creditors. See our article on unregistered charges in a liquidation.
Frequently asked questions
Does crystallisation need to be registered with ACRA?
No. Crystallisation does not create a new charge, so there is no separate lodgement. The registered charge particulars should already disclose any negative pledge or restriction in the debenture.
Can a crystallised floating charge float again?
Many debentures allow the lender to “decrystallise” the charge, for example after a default has been cured. The legal effect of decrystallisation is not settled in Singapore, so any arrangement should be documented in writing and reviewed with a lawyer.
Does selling a large asset crystallise the floating charge?
Not by operation of law, according to the Court of Appeal in Malayan Banking, unless it amounts to the company ceasing to trade as a going concern. But it may breach the debenture or trigger a contractual crystallisation clause, so check the document first.
Does crystallisation before liquidation stop employees ranking ahead of the bank?
No. The preferential debts rule in IRDA s 203(6) applies to any charge that was a floating charge when it was created, whether or not it has since crystallised.
Is a receiver’s appointment always a crystallising event?
Appointing a receiver over the charged assets under the debenture crystallises the floating charge over those assets, because the company loses control of them.
