• Steps: Use chip card → Find ATM → Enter amount → Collect cash
• Cost: About NT$800-1200 loss on NT$50,000, cross-bank fee NT$5

• Cost: About NT$500-800 loss on NT$50,000

Spot Rate vs Cash Rate, What’s the Difference?

Cash Rate: The price banks offer for physical bills/coins, usually 1-2% worse than market price because of handling costs. For example, Bank of Taiwan’s cash selling rate is 0.2060 NT$/Yen.

Spot Rate: The electronic price in the foreign exchange market with T+2 settlement, closer to the real international market price, but takes 2 working days to settle. At the same time, the spot rate is about 0.2062 NT$/Yen, slightly cheaper by NT$0.0002.

Exchanging NT$10,000, cash rate might result in a NT$200-300 loss, while spot rate only NT$50-100. Although the difference seems small, for NT$50,000 it exceeds NT$1000.

Suggestion: Use cash for small amounts (below NT$5000) for urgent needs, online remittance (spot rate) for larger amounts, and fixed deposits for investment to avoid frequent cashing out.

Is it a good time to exchange Yen now? Annual exchange rate analysis

Short-term trend: NT$ to Yen at 4.85, up 8.7% from 4.46 at the start of the year; second half demand for exchange increased by 25%.

Mid-term outlook: Japan’s central bank governor Ueda Kazuo’s hawkish comments pushed rate hike expectations to 80%, with a possible rate increase to 0.75% at the December 19 meeting (30-year high), Japanese bond yields hit a 17-year high of 1.93%. USD/JPY has fallen from 160 to 154.58 since the start of the year, likely to fluctuate around 155, with a medium-long term target below 150.

Investment judgment: Yen has both hedging and interest income functions, but short-term arbitrage carries risk, with volatility of 2-5%.

Exchange strategy:

• For travel: Exchange now, as domestic tourism recovers and JPY/TWD is stable
• Asset allocation: Buy in installments, NT$5000-10,000 monthly, to average costs and avoid chasing highs
• Arbitrage: Watch the US-Japan interest rate spread (currently 4.0%), set stop-loss when risks increase

How to preserve and grow Yen after exchange?

Holding Yen without earning interest is not ideal. Three suitable options for small investors:

1. Yen Fixed Deposit (safest) Minimum NT¥10,000, annual interest 1.5-1.8%, open accounts at E.SUN or Bank of Taiwan. NT¥50,000 6-month deposit yields NT¥450-540.

2. Yen ETFs (moderate growth) Yuanta 00675U tracks Yen index, can buy fractional shares, annual management fee 0.4%, suitable for monthly investment. When Japan’s central bank hikes rates and Yen appreciates, ETFs also rise.

3. Forex swing trading (advanced) Trade USD/JPY or EUR/JPY on platforms like Mitrade, with zero commissions and low spreads, offering stop-loss and take-profit tools. Use intraday or swing strategies to capture exchange rate fluctuations, suitable for experienced investors.

Tip: Yen is a strong hedge, but also volatile. Geopolitical risks (Taiwan Strait/Middle East), arbitrage unwinding can weaken Yen. Limit allocation to no more than 10% of assets, and hedge against Taiwan stocks.

Quick FAQs

Q1: How much Yen for NT$10,000? Use formula “Yen = NT$ × rate”. At Bank of Taiwan cash rate 0.2060, NT$10,000 ≈ 48,500 Yen. Using spot rate 0.2062, about 48,500-48,700 Yen, difference of 200 Yen.

Q2: What to bring for counter exchange? ID + passport (foreigners bring passport + residence permit). If online reservation, also bring transaction notice. Under 20 years old need parent accompaniment; over NT$100,000 requires source of funds declaration.

Q3: Daily limit for foreign currency ATM withdrawal? From October 2025, each bank’s own card limit is NT$100,000-150,000/day; other bank cards depend on issuing bank. Use your own bank card to avoid NT$5 cross-bank fee. During peak times (airports), cash may run out, so withdraw early.

Summary

Exchanging Yen is no longer just for travel but also a form of hedging and small asset management. Master the four key points: “Choose bank, pick timing, buy in installments, and invest after exchange” to minimize costs and maximize returns.

For beginners: the fastest way is NT$50,000 online remittance + airport pickup to save the most, or use foreign currency ATM for emergencies. After exchange, consider Yen fixed deposits (earn 1.5-1.8% annually) or ETF monthly investment (long-term hedging). This way, traveling abroad becomes more cost-effective, and your assets gain extra protection.
