Singaporeans read a great deal of American advice about credit scores: keep utilisation under thirty per cent, never let anyone pull your file, watch the number climb from 700 to 750. Almost none of it describes the system that actually decides whether a Singapore bank lends to you.
The sharpest difference is one the advice cannot account for, because the American system has no equivalent. A Singapore credit report can come back with no score at all — and there are five separate ways that happens, only some of which are good news.
Eight grades, and what each one is really saying
Credit Bureau Singapore issues a four-digit score paired with a two-letter risk grade. The grade, not the number, is what matters. Each letter pair corresponds to a specific probability of default, not a vague marketing adjective.
| Grade | Score | Probability of default |
|---|---|---|
| AA | 1911–2000 | 0.27% or less |
| BB | 1844–1910 | 0.27% – 0.67% |
| CC | 1825–1843 | 0.67% – 0.88% |
| DD | 1813–1824 | 0.88% – 1.03% |
| EE | 1782–1812 | 1.03% – 1.58% |
| FF | 1755–1781 | 1.58% – 2.28% |
| GG | 1724–1754 | 2.28% – 3.48% |
| HH | 1000–1723 | 3.48% or more |
The bands are uneven. AA spans ninety points and HH spans seven hundred and twenty-three. This is because the scale is built around default probability rather than equal numerical slices, so most of its range is used to describe borrowers in trouble.
A small error circulating in the local personal-finance press shows how this figure travels. Several widely-read Singapore sites give the GG and HH boundary as 3.46%. The bureau's own document says 3.48%. The table is published as an image inside a PDF, so nobody who copies it is reading it — they are copying each other, and a single mistranscribed digit has propagated across most of the results a search returns.
Five ways to have no score
When the grade is HX, HZ, GX, BX or CX, the score field reads "not applicable". These five grades are distinct from one another and do not simply mean a low score:
- HX — a public record: a writ of summons or a bankruptcy filed against you. This is the worst item on the list, not a neutral one.
- HZ — currently ninety days or more past due, or written off, with more than $300 outstanding.
- GX — enquiries only, with no credit file behind them.
- BX — every account you hold has been closed.
- CX — insufficient credit activity to assess.
The trap is that "no score" sounds like a blank slate. Two of these five are adverse findings, and one of them names a bankruptcy. Telling someone an HX grade means they are unscored is the opposite of the truth; the file is reporting a major adverse event.
The other trap sits at the bottom of the list. Closing every card you hold does not produce a clean report; it produces BX, and a lender reading BX cannot see a repayment record at all.
The record that never drops off
The most repeated claim about Singapore credit reports is that defaults clear after three years. That is true of settled ones only.
| Record | How long it shows |
|---|---|
| Enquiries | 2 years from the enquiry |
| Default — negotiated or full settlement | 3 years from the status date |
| Default — outstanding, partial payment, sold off | indefinitely |
| Bankruptcy | 5 years from discharge, not from filing |
| Writ of summons, concluded | 3 years |
| Closed accounts | 3 years from closure, showing 12 months of history |
An unsettled default is displayed for as long as it remains unsettled. There is no clock running in your favour, which inverts the usual advice about waiting things out. The bankruptcy row is the other one people get wrong: the five years run from discharge, so the total time on file depends on how long the bankruptcy itself lasted.
Looking at your own file costs nothing but money
Checking your own report has no effect on your grade, and the bureau says so plainly — self-enquiries do not affect the score, and neither do the periodic reviews a lender runs on facilities you already hold. The American distinction between a soft pull and a hard pull exists here; it is just never called that. This is why imported advice on the topic can be misleading.
Applications are a different matter. "Too many enquiries" is a named factor, keyed on how frequent and how recent your credit applications are. Enquiries stay on the report for two years — though note that is how long they are displayed, which is not the same as how long they weigh on the score, and the bureau does not publish the second figure.
The report costs $8.72 including GST. There is a free copy, and the condition on it is narrower than usually stated but also more generous in one respect: you may request it within thirty days of a lender approving or rejecting an application, not only rejecting one. Approval counts. What does not exist is an annual free entitlement of the American kind — a Singaporean who wants to look without applying for anything pays each time.
The thirty per cent rule is not a rule here
Utilisation does appear in the bureau's published factors, as "utilisation pattern — the amount of credit owed or used on accounts". That is a level, not a ratio, and no threshold is attached to it anywhere in what the bureau publishes. No thirty per cent, no ten per cent, no per-card figure.
The scoring window is also shorter than the imported advice assumes: twelve months of repayment conduct. A bad year carries enormous weight, but a misstep from five years ago does not enter the calculation, provided nothing from it remains on the file as an unsettled default.
What the regulator does not do
The Monetary Authority of Singapore licenses exactly one consumer credit bureau, and it is worth being precise about how little that licence covers. The regulator states that it does not prescribe how a bureau derives a score and cannot direct one to amend yours; that retention periods are the bureau's and its members' decision rather than the regulator's; and that it operates no credit bureau itself and cannot see what banks submit.
The one thing the law is firm about is what banks may hand over. The Banking Act permits disclosure strictly necessary to create a credit report, with deposit information expressly excluded and onward disclosure barred. Your bureau file knows what you owe. It does not know what you have.
The other bureau in the same building
Licensed moneylender debt does not appear in your credit report. It goes to the Moneylenders Credit Bureau, which sits under the Ministry of Law rather than the Monetary Authority, and which the same company has operated since July 2021. A report from it costs fifty cents.
Two bureaux, one operator, two different ministries, and no traffic between the files. Anyone reasoning about their own borrowing needs to know which of the two a given lender reports to.
Malaysia built it the other way up
Across the causeway the central bank runs the underlying register itself. CCRIS is owned and operated by Bank Negara Malaysia, holds twelve months of financing and repayment history, and is free to the borrower through eCCRIS. The central bank is explicit that it does not alter the data and issues no score of its own.
The scoring layer sits above it: three private agencies registered under the Credit Reporting Agencies Act may pull CCRIS data with the borrower's consent. So a Malaysian gets the raw record free from the central bank and pays only for the interpretation, while a Singaporean pays $8.72 for a file the regulator never sees.
Where this leaves a borrower
The American playbook fails in both directions here. It manufactures fear of checking your own file—which has no consequences—while promoting a utilisation threshold that does not exist. At the same time, it is silent on what genuinely bites: an unsettled default that never expires, and five non-scored grades that look like a clean slate to the unwary.
How this was checked
The grade table, the non-scored definitions, the retention periods and the contributing factors are from Credit Bureau Singapore's own Consumer Credit Report Explanation, in the version dated 1 April 2026, and from its consumer pages; the scored-grade table is a raster image inside that PDF and was read by rendering the page rather than by extracting text. The single-licence finding is from the Monetary Authority's financial institutions directory, and the regulator's statements about what it does not do are from its own published answers. The disclosure rule is the Banking Act 1970, Third Schedule, Part 2. The Moneylenders Credit Bureau designation is from the Ministry of Law's announcement of 25 June 2021 and its fee from the bureau's own page. The Malaysian material is from Bank Negara Malaysia's CCRIS page. All were read on 18 September 2026.
One figure deliberately omitted: the CTOS score range that circulates widely for Malaysia could not be found on the agency's own pages, which render it in a way that resists reading, so it is left out rather than repeated from a comparison site — the same failure mode that put 3.46% into the Singapore tables above.
