Key distinction: Market FX, a bank's posted rate, and your executable transaction rate can differ.
Taiwan does not fix TWD at one permanent USD price
The central bank describes Taiwan's framework as a managed floating exchange-rate regime.
Market supply and demand generally drive daily FX
Trade flows, portfolio flows, corporate conversion, rate expectations, and global dollar conditions can affect the market.
The central bank may act during excessive volatility
The central bank states that it can intervene to maintain market order and dynamic stability when short-term flows cause excessive volatility.
Managed floating is not the same as a fixed rate
Official stabilization activity does not mean a fixed daily exchange rate is administratively set.
Primary / official sources
Posted rates change continuously. Actual transactions use the rate and fees shown by the executing bank, broker, or payment provider.
