Japanese Yen Investment Value Reversal: Exchange Cost Optimization Guide × 4 Major Channels Practical Comparison

Under the pressure of TWD depreciation, the Japanese Yen has upgraded from a simple “travel emergency fund” to a hedge asset. On December 10, 2025, the TWD/JPY exchange rate reached 4.85, appreciating 8.7% since the beginning of the year, making the currency exchange gains quite substantial. But the key question is: How to exchange to minimize costs? We will analyze the true costs and suitable scenarios for four different currency exchange channels.

Is it cost-effective to exchange JPY now? Market opportunity insights

Brief answer: Yes, but operate in batches.

The Bank of Japan is on the verge of raising interest rates—Governor Ueda and male hawkish comments have pushed market expectations of rate hikes to 80%, with a projected increase of 0.25 basis points to 0.75% at the December 19 meeting (a 30-year high). Meanwhile, Japanese bond yields have hit a 17-year high of 1.93%, and USD/JPY has fallen from the early-year high of 160 to around 154.58 now.

Implications for investors:

• The Yen, as one of the three major safe-haven currencies (alongside USD and CHF), is suitable for hedging Taiwan stock market volatility
• Short-term risks include profit-taking and arbitrage closing, with potential fluctuations of 2-5%
• Medium to long-term forecast: USD/JPY will stay below 150, with room for Yen appreciation

Data shows that Taiwan’s foreign exchange demand increased by 25% in the second half of the year, mainly driven by tourism recovery and hedging needs.

4 currency exchange methods: Cost vs. convenience practical comparison

Method 1: Bank counter cash exchange — Traditional but most expensive

Carry TWD cash directly to a bank branch or airport counter to exchange for JPY cash.

Cost structure: Using “cash selling rate” (about 1-2% worse than spot rate). For example, Taiwan Bank’s cash selling rate on December 10, 2025, is approximately 0.2060 TWD/JPY (about 4.85 JPY per TWD). Some banks charge an additional handling fee of NT$100-200.

Estimated cost for exchanging NT$50,000: Loss of NT$1,500-2,000

Suitable scenarios: Not familiar with online operations, urgent needs at the airport (considering airport exchange hours and operational restrictions)

Method 2: Online exchange + counter/ATM withdrawal — Preferred for advanced investors

Use online banking or app to convert TWD into JPY and deposit into a foreign currency account, using “spot selling rate” (about 1% better than cash rate). If cash is needed, withdraw at counters or foreign currency ATMs.

Cost structure: About 1% spread, plus withdrawal handling fee (starting from NT$100). For example, after currency exchange via E.SUN Bank app, withdrawal fee is the difference between spot and cash rates, minimum NT$100.

Estimated cost for exchanging NT$50,000: Loss of NT$500-1,000

Advantages: Observe exchange rate trends, buy in batches at lows (e.g., when TWD/JPY drops below 4.80) to average costs. After acquiring JPY, can directly transfer to a Japanese fixed deposit (current annual interest rate about 1.5-1.8%) to increase passive income.

Suitable for: Readers experienced in forex, frequently using foreign currency accounts

Method 3: Online currency conversion + airport pickup — Optimal for planned trips

No need for a foreign currency account. Fill in currency, amount, pickup branch, and date on the bank’s official website. After completing the transfer, bring ID and transaction notification to pick up in person. Taiwan Bank and Mega Bank offer this service, with appointment options at airport branches.

Cost & convenience:

• Taiwan Bank’s “Easy Purchase” online currency conversion is fee-free (pay NT$10 via Taiwan Pay), with about 0.5% exchange rate advantage
• Airport exchange time advantage: Taoyuan Airport has 14 Taiwan Bank counters, 2 of which operate 24 hours, allowing direct withdrawal before departure without extra queues
• Estimated cost for NT$50,000 exchange: NT$300-800 loss

Suitable for: Travelers with strong planning, completing reservations 1-3 days before departure

Method 4: Foreign currency ATM 24-hour withdrawal — Most flexible for emergency needs

Use chip-enabled debit/credit cards at foreign currency ATMs to withdraw JPY cash, supporting 24-hour operation and interbank transactions (only NT$5 fee for deduction from TWD account). E.SUN Bank’s foreign currency ATMs allow withdrawal from TWD accounts, with a daily limit of NT$150,000 and no exchange fee.

Cost structure: NT$5 interbank fee per transaction, with per-transaction limit varying (usually NT$150,000/day)

Estimated cost for NT$50,000: NT$800-1,200 loss

Notes: Limited ATM locations (~200 nationwide), fixed denominations (1,000/5,000/10,000 JPY), cash may run out during peak times. Not recommended to wait until the last minute to withdraw.

Suitable for: Office workers needing immediate cash without time to visit banks
