USD/THB — US Dollar to Thai Baht

USD/THB is also a practical reference for the large flow of foreign visitors converting dollars to baht for travel in Thailand, making tourism-driven demand one of the more visible everyday drivers of this pair.

USD/THB measures how many Thai baht one US dollar buys. The baht is one of the more closely tracked Southeast Asian currencies, in large part because Thailand's economy leans heavily on tourism and trade, both of which flow directly through this exchange rate.

The Bank of Thailand (BOT) manages the baht under a managed float, allowing it to move with market forces while occasionally smoothing volatility. Thailand's large tourism sector is a major driver: foreign visitor spending is a significant current-account inflow, so shifts in tourist arrivals — whether from regional travel patterns or global travel demand — can move the baht noticeably.

The baht also shows a notable correlation with gold prices, partly because Thai households and investors are active participants in the physical gold market, and gold-related capital flows can show up as swings in baht demand. Thailand's broader trade balance rounds out the main drivers of the pair.

This page shows an indicative mid-market USD/THB rate that can update intraday through the trading week. Every API response carries a source and market_session field, so you can tell whether a given quote was a live tick or a daily fix. Rates are indicative only, not for settlement or regulated trading.

Frequently asked questions

What does USD/THB measure?
USD/THB states how many Thai baht you receive for one US dollar. A rate of 36.5 means one dollar buys 36.5 THB.
Is USD/THB a live rate on exchangerate.dev?
USD/THB is served as an indicative mid-market rate that can update intraday through the trading week. Check the source and market_session fields on each API response to see whether a specific quote was a live tick or a daily reference fix.
How do I get the USD/THB rate via the API?
GET /v1/latest/USD?symbols=THB returns the indicative rate along with source, market_session, and timestamp. The reverse (THB as base) is also supported. The free tier covers it, no credit card required.
Why does tourism affect USD/THB?
Tourism receipts are a major component of Thailand's current account. When foreign visitor arrivals and spending rise, more foreign currency flows into Thailand and gets converted to baht, which can support the currency; a slowdown in tourism can work the other way.
Why is USD/THB correlated with gold prices?
Thai households and investors are active buyers and sellers of physical gold. Because gold is typically priced in US dollars, large swings in gold demand can translate into dollar-baht conversion flows that show up in the exchange rate.
Does the Bank of Thailand fix the baht's value?
No. The BOT operates a managed float, meaning the baht moves with market supply and demand, but the central bank can intervene to smooth unusually sharp or disorderly moves.
Is USD/THB suitable for settlement or trading decisions?
No. exchangerate.dev provides indicative rates for reference and informational use only — not for settlement, regulated trading, or as a source-of-record price.
