Yen investment is booming? Different banks have different exchange rates, the secret to paying an extra 2,000 TWD on 50,000 TWD

Under the pressure of TWD depreciation, many people turn to JPY for hedging or exchange currency before traveling. But did you know? For the same 50,000 TWD exchanged into JPY, simply choosing different banks or exchange channels can result in cost differences of up to NT$2,000—equivalent to the price of a cup of bubble tea.

This article provides an in-depth analysis of the Taiwan JPY exchange market to help you find the most cost-effective options.

Current Market: JPY Appreciated by 8.7%, but Volatility Risks Cannot Be Ignored

As of December 2025, TWD to JPY exchange rate reached 4.85, up 8.7% from the beginning of the year at 4.46. The main drivers of this appreciation are three factors:

Bank of Japan Rate Hike Expectations — Hawkish comments from Governor Ueda Kazuo, with market expectations of an 80% chance of rate hikes, expecting a 0.75% rate at the December 19 meeting (a 30-year high), with Japanese bond yields reaching a 17-year high of 1.93%.

Weakening US Dollar — The US enters a rate cut cycle, with USD/JPY falling from 160 at the start of the year to 154.58. Short-term fluctuations may bring it back to 155, but medium to long-term forecasts suggest below 150.

TWD Depreciation Expectations — Relative appreciation makes exchanging into JPY an effective hedge against Taiwan stock market volatility.

Risk Warning: Although JPY as a safe-haven currency is stable, short-term arbitrage closing risks may cause 2-5% fluctuations. Geopolitical conflicts (Taiwan Strait/Middle East) could also depress the exchange rate. Staggered exchange is key.

Revealing Bank JPY Exchange Rates: Choosing the Right Bank Can Save NT$1,000

Many think all banks are the same, but the “cash selling exchange rate” varies significantly. Here are the latest data as of December 10, 2025 (estimated for exchanging NT$50,000):

High-Cost Group — Cash exchange at counter Taipei Fubon Bank (0.2069) + NT$100 per transaction fee = Loss NT$1,900
Cathay United Bank (0.2063) + NT$200 per transaction fee = Loss NT$2,100

Medium-Cost Group — Online exchange with cash withdrawal E.SUN Bank (0.2067) + NT$100 withdrawal fee = Loss NT$1,100
Hua Nan Bank (0.2061) no fee = Loss NT$800

Low-Cost Group — Online exchange reservation Bank of Taiwan (0.2060) no fee = Loss NT$500-700
Mega International Bank (0.2062) no fee = Loss NT$600-800

Why the difference? Banks price based on “cash selling exchange rate,” not the spot rate in the international market. The former is 1-2% worse than the latter, plus different handling fee policies, creating cost gaps.

Newbie Must Know: Cash Exchange Rate vs. Spot Rate

Cash exchange rate: The rate banks offer for physical bills/coins, delivered instantly but usually 1-2% worse than market price, plus handling fees.

In simple terms: Use cash exchange rate for cash transactions (more expensive), and spot rate for account transfers (cheaper).
