Sources & Methodology
Exchange rates are mid-market rates sourced from the Exchange Rate API, which aggregates data from central banks and financial institutions. Historical data is provided by the Frankfurter API (ECB reference rates). Rates are cached for 12 hours and are for informational purposes only. Actual transaction rates from banks and services may differ.
Reference notes for USD/SGD
When you typically see USD/SGD
Singapore is a frequent regional HQ for US tech companies, which produces a steady flow of intra-company USD billing recorded to SGD books locally. US SaaS companies billing Singapore-domiciled customers in USD generate the most volume. US business travel to Singapore — APAC conferences, regional summits, supplier and partner meetings — is the third recurring source. Singapore hotel and dining rates are high, so per-receipt amounts tend to be larger than for other Asian destinations.
How USD/SGD behaves in accounting
For a US-domiciled filer, U.S. Treasury quarterly USD/SGD is the official reference. For Singapore-domiciled accounting, the Monetary Authority of Singapore publishes daily reference rates that local accountants use; MAS is not currently implemented as a Zenrate fetcher. SGD is one of the more stable Asian currencies against USD, partly because MAS manages it within an undisclosed trade-weighted band. Daily moves rarely exceed 0.5% under normal conditions. This stability means policies don't matter as much: transaction-date and prior-month-end usually agree within 0.3% over a month. For Singapore SaaS subscription billed monthly, prior-month-end is the simplest defensible choice.
Common conversion mistakes for USD/SGD
Treating SGD and USD as interchangeable because the rates have hovered around 1.30–1.40 SGD per USD for a long time. They are not; small percentage moves on the actual amount paid become visible at year-end reconciliation. Second: applying a Singapore GST (currently 9%) to USD-priced invoices when the invoice already states USD-inclusive pricing. Most US-billed Singapore subscriptions are NOT GST-applicable unless the SaaS vendor has registered with IRAS; check the invoice. Adding 9% where it does not apply produces a phantom SGD overstatement. Third: confusing Singapore Dollar with the Brunei Dollar (BND), which is held at parity with SGD by an old agreement but is a separate currency. Some statements label them inconsistently.
What Zenrate stores for USD/SGD
Live conversion via exchangerate-api.com (USD-base, direct USD/SGD). Twelve-hour cache. Historical: U.S. Treasury USD/SGD quarterly. ECB cross-rated through EUR via Frankfurter on any date. MAS daily rates would be the ideal source for Singapore-side accounting but are not in the implemented sources today. All six rate policies work via the available sources. Stability of the pair means policy choice has minimal accounting impact for most users.
