Methodology & transparency
How we source & update our data
Every rate, yield, and date on this site traces back to a primary source — a public regulator feed for the government instruments, and each issuer's own filings for the S-REITs we track. This page explains where the numbers come from, how often they refresh, what we compute versus simply surface, and how we fix mistakes when we find them.
Where the data comes from
SSB, T-bill, and SGS figures come directly from the Monetary Authority of Singapore public statistics API, distributed under CC-BY 4.0. We surface the values MAS publishes — cut-off yields, median yields, issue and auction dates, allotment figures — as they are reported.
For facts beyond the bond data itself, we cite the authority that owns the rule: IRAS for tax treatment, the CPF Board for CPF rates and scheme rules, and SGX/CDP for secondary-market trading and settlement. Every numeric claim in our explainers links to its primary source.
Singapore REITs work differently. S-REIT fundamentals aren't published on a regulator feed, so we curate them by hand from each REIT's own investor-relations disclosures — results announcements, distribution notices, and stock-information pages — never from SGX's licensed market-data feed. We record each unit price as a dated snapshot and compute the trailing distribution yield ourselves from the published payouts, so no market-data licence attaches to a figure we work out from issuer results. The full method is on the REIT methodology page.
How often it updates
- Ingest: an automated job fetches fresh MAS data every 4 hours, with retries and validation.
- Rebuild: when the data changes, the static pages are re-rendered and redeployed automatically.
- Freshness badge: every page shows when the pipeline last checked MAS data; it flags as stale after 26 hours. See the freshness API.
- Live vs. written figures: rate numbers pulled from the live data layer are always current; figures written into article prose carry an explicit "as of" date and a pointer to verify.
- REIT data is curated by hand, not on the MAS pipeline. Unit prices are dated snapshots — a page flags any price past 30 days as possibly outdated, and distribution, NAV, and gearing figures older than about eight months are flagged too. When a material corporate event (such as a rights issue) changes a REIT's underlying figures, the affected numbers show "under review" rather than a stale value.
What we report vs. compute
We surface the figures a regulator publishes and, for the S-REITs, compute yields from each issuer's own results — we do not re-rank, score, or recommend products. Where a page derives a value — a chart's trailing range, a worked interest example, or a REIT's trailing distribution yield — the calculation is shown so you can follow the arithmetic. The underlying inputs stay the published MAS values or the issuer-disclosed REIT figures, never a re-priced or estimated number; time-sensitive third-party rates (such as fixed-deposit or cash-account rates) are labelled "as of" a date and linked out, because they change frequently.
Corrections
We aim to be accurate, but errors happen. When we find or are told about a factual mistake, we correct it fully and — for anything material — add a dated note saying what changed, rather than silently overwriting it. Spotted something wrong? Email hello@sgyieldhub.com with the page and the figure, and we'll check it against the primary source.
