Singapore's currency rules begin from a blunt premise: a damaged note or coin is, by default, worth nothing. The Currency Act 1967 gives damaged money no standing of its own. A mutilated note or coin has no guaranteed worth, and a holder cannot compel the Monetary Authority of Singapore (MAS) to buy it back at face value. Any refund is a favour, not an entitlement, and it disappears the moment there is a sign the money was deliberately damaged.
That framework, set out in MAS's mutilated currency guidance, matters well beyond the individual who accidentally tears a note or drops coins into a fire. It shapes how every commercial bank, retailer and cash-handling operation in Singapore must treat damaged money, and it draws a hard line between accidental damage and the wilful mutilation the Act treats as a criminal offence.
The Starting Point: No Value, No Entitlement
MAS is the sole issuer of Singapore currency and the authority that decides whether a damaged note or coin is worth anything. The default position is unforgiving: damaged money counts for nothing, merchants may turn it away, and the central bank is under no obligation to reimburse anyone who presents it.
What MAS offers instead is a choice it need not make. Where a damaged note or coin is authenticated as genuine and shows no sign of deliberate destruction, the central bank can elect to reimburse part or all of its value as a concession, weighed case by case. The important point for anyone handling cash is that this is a favour MAS may extend, not a right the holder can demand.
How a Damaged Note Is Valued
For notes, MAS applies a two-stage test. First, two gates must be cleared: the note must be authenticated as genuine, and there must be nothing to suggest it was wilfully or deliberately damaged. Any explanation the holder offers for the damage is itself weighed for reasonableness.
Only once those gates are passed does value turn on how much of the note survives:
- Two-thirds or more survives: the full face value is paid.
- Between one-third and two-thirds survives: half the face value.
- One-third or less survives: nothing is paid.
Where a note arrives in fragments, MAS adds up the surviving portions, provided they plainly belong to the same note rather than several. Higher denominations carry an extra safeguard: for the $1,000 and $10,000 notes, MAS will not assess any value unless both serial numbers survive, each with at least five of its characters intact. And where the missing part of a note can be shown to have been destroyed, so that it can never be presented for a second claim, MAS may pay up to the full face value.
Coins Are All or Nothing
Coins are treated far more starkly, with no sliding scale. A coin qualifies for a face-value refund only if it is genuine and shows no sign of deliberate damage. It is disqualified if it has been cut or chipped, holed or defaced, or left warped or dented, and, for the Third Series one-dollar bi-metallic coin, if its inner core and outer ring have separated. Anything that fails those conditions is simply worthless in MAS's eyes, with no partial award available.
Where to Take Damaged Money
The procedure deliberately keeps MAS out of the front line. Damaged money goes in through the banking system: a holder hands the notes or coins to a commercial bank where they keep an account, and the bank credits whatever value is assessed. Coins have a second drop-off point as well, in Certis CISCO Secure Logistics, the operator MAS appoints to manage circulation coins.
Anyone without a Singapore bank account is directed to contact MAS through its online feedback form to arrange a refund. One instruction is emphatic: damaged currency should never be posted to MAS. If a bank or coin operator refuses to accept the money at the counter, the depositor can escalate the matter to MAS, noting the branch involved, the counter staff, and the date and time of the attempt.
The Anti-Fraud Line
The framework's sharpest edge is its treatment of deliberate damage. Mutilating currency is not merely a bar to reimbursement; it is an offence under the Currency Act. Where someone sees money being deliberately damaged, MAS's guidance steers them to the police and asks to be informed as well. The wilful-damage gate is what stops the refund system from being gamed, whether by someone trying to reconstruct value from notes that were intentionally cut or by attempts to inflate a claim. It fits within Singapore's wider tightening of financial-crime controls, where the authorities have steadily expanded the tools available against manipulation and abuse.
Two related risks sit alongside it. Genuineness screening means counterfeits are worth nothing and, under the Act, are liable to forfeiture, with the practical route being to surrender suspected fakes to the Singapore Police Force. Banks also increasingly encounter notes stained by security dye from an intelligent banknote neutralisation system, or IBNS, the staining and degradation agents built into ATMs and cash-in-transit boxes to render stolen cash unusable. The Currency Act expressly recognises IBNS technology, and a dye-stained note raises obvious provenance questions for any institution asked to exchange it.
Why It Matters for Cash-Handling Compliance
For compliance and operations teams, the mutilated-currency rules are a quiet but concrete part of the cash-handling control environment. Retail banks sit at the centre: their branch staff make the first assessment, credit customer accounts and become the escalation point a customer will cite if a deposit is turned away. They are also the institutions MAS is progressively drawing into shared financial-crime information-sharing. Clear internal procedures, aligned with MAS's genuineness and wilful-damage gates, reduce both customer disputes and the risk of processing manipulated notes.
Several concrete steps follow from the framework:
- Train front-line staff on the two-thirds and one-third note thresholds and the coin exclusions, so counter assessments are consistent and defensible.
- Treat deliberate damage as a red flag, not just a refund question: intentionally mutilated notes, dye-stained cash and suspected counterfeits should trigger escalation, a police report where warranted, and notification to MAS.
- Document refusals and escalations with the branch, staff and timestamp details MAS itself requests, so any dispute can be resolved cleanly.
- Route suspected counterfeits to the police rather than returning them to the customer, consistent with the Act's forfeiture provision.
None of this is new law, but it is easy to overlook until a torn $10,000 note or a dye-stained bundle lands at a counter. Singapore's approach is characteristically precise: value flows only from genuine, honestly damaged currency, and never from money that someone set out to destroy. For the institutions that handle the country's cash, the lesson is to make MAS's gates their own, verifying genuineness, watching for deliberate damage, and documenting every judgement call.
