Cathay United Bank is one of Taiwan's largest private banks and the banking arm of Cathay Financial Holding, one of the island's biggest financial groups, whose name also sits on Cathay Life Insurance and a sprawl of financial businesses. Headquartered in Taipei, it grew through the merger of United World Chinese Commercial Bank and Cathay Commercial Bank in the early 2000s into a nationwide network of branches and ATMs. For US travelers the practical points are local and simple: Cathay United machines dispense New Taiwan dollars at the interbank rate, add no operator surcharge on most foreign-card withdrawals, and sit alongside Taiwan's enormous convenience-store ATM network, so a surcharge-free withdrawal is never far away in Taipei or the other cities.
What Cathay United Bank charges foreign cards
| Fee component | Amount | Paid to |
|---|---|---|
| Cathay United operator fee (foreign card) | NT$0 on most machines | Cathay United adds no operator surcharge for most cards |
| Exchange rate | Mid-market (interbank) | Visa or Mastercard network |
| Visa / Mastercard network fee | ~1% | Card network, baked into total |
| Your home bank's foreign ATM fee | $2-5 | Your home bank, unless waived (Schwab, Wise) |
| Your home bank's FX conversion fee | 1-3% | Your home bank, unless 0% FX card |
| DCC markup (if accepted) | +4-12% | Always decline. Pick New Taiwan dollars every time the screen offers your home currency. |
Cathay United is part of Cathay Financial Holding. Taiwan has no BoA Alliance partner, so BoA debit pays BoA's 3% anywhere. Withdrawal limits run roughly NT$20,000-30,000 per transaction.
Why Cathay United pairs perfectly with an EasyCard
The smart Taiwan setup is a bank or convenience-store ATM for cash, the EasyCard and a credit card for everything else, and Cathay United fits that perfectly. Taiwan runs heavily on the EasyCard stored-value card, which taps you onto the Taipei MRT, buses, and into 7-Eleven and FamilyMart, while cards cover hotels, chain restaurants, and Taipei 101. So although Cathay United ATMs are widespread and surcharge-free, you will withdraw less than you expect. Use a Cathay United machine (or any nearby convenience-store ATM) for a modest New Taiwan dollar float for the night markets and traditional eateries, the genuine cash holdouts, and let the EasyCard and a card carry the rest.
Bank of America customers should note there is no fee-free ATM in Taiwan at all: with no Taiwanese BoA Alliance partner, a BoA card pays its 3 percent non-network fee even at Cathay United. A Wise or Schwab card is the better tool, and it doubles as the way to load an EasyCard at the real rate.

Cathay United vs CTBC: the actual decision
| Cathay United | CTBC | |
|---|---|---|
| Foreign-card operator fee | NT$0 (most machines) | NT$0 (most machines) |
| BoA Global ATM Alliance partner | No (none in Taiwan) | No (none in Taiwan) |
| Network style | Wide branch network | Very dense, incl. convenience stores |
| Parent group | Cathay Financial Holding | CTBC Financial Holding |
| Best known for | A top private bank & insurer group | Cards & the widest ATM reach |
Decision tree: for cost they are effectively identical (both surcharge-free at the interbank rate on most machines, neither a BoA Alliance partner), so use whichever is nearest. CTBC tends to have the denser machine reach, including many convenience-store units; Cathay United is just as cheap. Either way, the bigger move is pairing the bank with an EasyCard and a no-FX-fee card.
Best card pairing with Cathay United Bank
Wise plus an EasyCard, Cathay United for the float
Because the EasyCard and credit cards cover so much, the card matters more than the ATM. A Wise debit card gives zero FX markup and the real interbank TWD rate at every terminal, including loading the EasyCard, and when you want cash a Cathay United (or convenience-store) machine dispenses it surcharge-free. Taiwan has no BoA Alliance partner, so a no-FX-fee card is clearly the best tool here.

Schwab adds zero foreign-transaction fee and refunds ATM operator fees worldwide. Cathay United machines are already surcharge-free for most cards, so Schwab + Cathay United is an effectively free Taiwan withdrawal, and Schwab covers you at any unbranded machine too. Still decline DCC and choose New Taiwan dollars.
Bank of America debit (no Alliance waiver in Taiwan)
Taiwan has no BoA Global ATM Alliance partner, so a BoA card pays its 3 percent non-network fee even at Cathay United. There is no fee-free Taiwanese ATM for BoA cards; a no-FX-fee card is the better option.
