Summary
Purpose
Compare USD/SGD rates shown on Google Finance and Yahoo Finance and identify discrepancies.
Result
Test — Failed (values inconsistent)
Recommendation
If authoritative rate required, confirm source (interbank feed) or refresh both pages. Minor timing differences may occur; consider capturing timestamps from each provider for reconciliation.
Findings
1.2933
1.2925
0.0008 (~0.062%)
Evidence
Google Finance page snapshot
Yahoo Finance currencies list snapshot
Verification Steps (what I did)
- Opened Google Finance USD/SGD quote URL: https://www.google.com/finance/quote/USD-SGD and captured the displayed rate (1.2933) and page timestamp.
- Took a screenshot of the Google Finance view (saved as screenshots/google_usdsgd.png).
- Opened Yahoo Finance currencies page: https://sg.finance.yahoo.com/markets/currencies and located the USD/SGD row (listed as 1.2925).
- Took a screenshot of the Yahoo currencies list (saved as screenshots/yahoo_usdsgd.png).
- Compared the numeric values shown on each site and computed the difference (0.0008).
Notes & Considerations
- Exchange rates on public finance pages are often refreshed in near-real-time and may come from different data vendors or have different update frequencies; small discrepancies are common.
- Google showed a visible timestamp (UTC) on its quote card; Yahoo displays rates in a table without a visible precise timestamp in the same area. For strict reconciliation, capture server timestamps or API feeds from each provider.
- This check is a functional/UI comparison only — it does not validate against an authoritative interbank rate.
