Key distinction: Market FX, a bank's posted rate, and your executable transaction rate can differ.
A stronger TWD buys more foreign currency
Travel, overseas spending, and foreign-currency purchases generally become cheaper, all else equal.
Currency can offset overseas investment gains
A U.S. stock may rise in dollars while TWD appreciation reduces part of the return after conversion back to TWD.
Corporate effects are more complex
Exporters and importers can have foreign-currency revenues, costs, hedges, and operations across multiple markets.
A weaker TWD broadly reverses the direction
Foreign currency becomes more expensive, while foreign-currency assets can receive a positive translation effect in TWD terms.
Primary / official sources
Posted rates change continuously. Actual transactions use the rate and fees shown by the executing bank, broker, or payment provider.
