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/THB
When you typically see USD/THB
US digital nomads and remote workers in Thailand are the largest cohort: paid in USD by US employers via Wise or US-based payroll providers, spending in THB locally. Their accounting needs are personal (US tax reporting in USD, often with a foreign earned income exclusion) but their day-to-day lookups are in this direction. US-based importers of Thai handicrafts, agricultural products (rice, fruit), and lower-cost manufactured goods round out the small-business flow. Third: US business travel to Bangkok — regional conferences, supplier-factory visits, occasional medical tourism. Per-trip receipt count is moderate, per-receipt amount small.
How USD/THB behaves in accounting
For a US-domiciled filer, the canonical reference is the U.S. Treasury quarterly rate for THB, supplemented by daily commercial rates for line-item accuracy. For a Thai-domiciled receiver of USD, Bank of Thailand publishes a reference but Thai SMEs more often use the rate their bank quoted at conversion. Zenrate cross-rates this pair through USD when using the ECB source (USD/EUR and THB/EUR fetched and combined). Direct USD/THB rates are not published by ECB. THB is moderately stable against USD with periodic interventions from the Bank of Thailand to manage capital flow. Daily moves of 0.3–0.7% are typical. Monthly-average policies are usually unnecessary here.
Common conversion mistakes for USD/THB
Treating Wise's mid-market rate at topup as the basis for accounting. Wise converts at the moment of payment, not at the moment of topup; if USD was held in a Wise USD balance and converted to THB at purchase, the rate to record is Wise's executed rate at the moment of the merchant transaction, not the rate when USD was added to Wise. Second: applying a single "average rate for the month" across a Bangkok work-month when the underlying receipts span days with materially different rates. Acceptable for personal budgeting; not acceptable if the receipts back a US tax filing where each entry should be at its specific date's rate. Third: omitting the 7% VAT on Thai receipts when computing the USD basis. The VAT is part of the THB amount paid and should be included before applying the USD rate.
What Zenrate stores for USD/THB
Live conversion via exchangerate-api.com (USD-base, direct USD/THB lookup). Twelve-hour cache. Historical: U.S. Treasury USD/THB quarterly via Treasury fetcher. ECB constructs the cross via Frankfurter (EUR/USD and EUR/THB on the requested date). Mizuho USD/THB is not a published series, so this pair has no direct Mizuho path. All six policies work. Prior-month-average on the ECB source iterates business days through Frankfurter, which is fast but rate-limited; use case is uncommon enough that this rarely surfaces.
