How to use this USD/THB reference
This page combines the latest USD/THB reference rate with 254 daily observations so you can check a figure, compare a period, or explain a conversion without turning the page into a forecast. The high, low, and average markers describe the observed window in this dataset, not a prediction of future movement.
For an invoice, receipt, payout, or accounting record, use the exact available rate for the relevant business date and keep the pair, source URL, and retrieval path beside it. FXpeek provides reference data for lookup, reporting, spreadsheets, and lightweight API workflows. It is not a bank, card, broker, remittance, or settlement quote, and nothing here is financial advice.
FXpeek sources USD/THB reference rates from public reference-rate data and refreshes the historical table daily, so the page always labels the latest available date. For a precise record, confirm the observation date on the row or graph before quoting the value, and use the date-specific lookup when the exact business day matters.
