THB/USD Rate — Last 30 Days
THB fell 1.48% vs USD this week — a clear short-term downtrend. Watch whether this continues or reverses.
The 7-day average rate is below the 30-day average — recent momentum favors USD strengthening vs THB. The trend may continue until a catalyst (rate decision, economic data) reverses it.
The rate is at its lowest point in 30 days. THB is under significant selling pressure. At lows, a bounce is possible — but only if the fundamental drivers change.
RSI of 23 means THB has fallen fast relative to USD and may be oversold. RSI below 30 often precedes a bounce — but in a strong downtrend, the rate can stay oversold for weeks.

Historical THB/USD Rates by Year
What drives the THB/USD rate?
Whether you're converting THB for travel, business, or investment, here's what drives the THB to USD exchange rate. The THB/USD exchange rate is determined by supply and demand in global currency markets, influenced by interest rate decisions from both central banks, economic data releases, inflation figures, and broader risk sentiment in financial markets. Trade flows between the two countries or regions also play an important role in long-term rate direction.
How to get the best THB to USD rate
The rate shown above is the interbank mid-market rate — the real exchange rate used between financial institutions. Individual customers cannot access this rate directly. Banks typically add a 2–3% spread on top, meaning you receive significantly less than the rate shown.
Online transfer services like Wise offer rates very close to the interbank rate with a small transparent fee of 0.5–1%. On a $1,000 THB exchange this typically saves $15–25 compared to a bank. Airport exchange booths charge the highest fees — often 5–8% above the interbank rate — and should be avoided for large amounts.
