They are indicative, change through the day, and are not official rates.

## About E.SUN Bank

 [www.esunbank.com](https://www.esunbank.com/)

## ![](https://flagcdn.com/24x18/tw.png) Latest board, read 21 Oct 2026, 09:09 Taiwan time (0h ago)

Bank’s own last-updated stamp: **2026-10-21T09:09:20+08:00** (as printed on its page, local time).

Board shown: **Spot (transfer) buy / sell**. Banks outside the Gulf publish several boards for the same currency — counter notes, drafts, transfers, cards — and this page shows one of them, the same one for every bank in Taiwan so the comparison is like for like. The others are on the bank’s own page.

## Frequently asked questions

### Is the E.SUN Bank rate the official Taiwan exchange rate?

No. E.SUN Bank sets its own buying and selling rates and changes them through the day. The official rate is published once per business day by the Central Bank of the Republic of China (Taiwan); it is shown in the Official column and is the figure accounting, tax and customs rules refer to.

### Which E.SUN Bank rate applies when I send money abroad?

The sell rate: you are buying foreign currency from the bank. When you convert foreign currency into TWD, the buy rate applies. Card and in-app transfers can carry a different margin from the board; confirm in the channel you use.

### How current is this table?

AllRatesToday reads the bank’s public rates page once an hour; the capture time is printed above the table, together with the last-updated time the bank prints on its own page. Rates may have changed since.
