Comprehensive Guide to Yen Investment and Currency Exchange: Debunking the Cost Myths of Four Major Channels

Did you know? The cost difference when exchanging NT$50,000 to Japanese Yen can be as high as NT$2,000. As of December 10, 2025, the NT$ to JPY exchange rate has risen to 4.85, signaling not just the peak travel season but also reflecting global capital flow trends. Why is the Yen worth paying attention to? Because it has long surpassed being just “pocket money for traveling abroad” and has become an asset class with both hedging properties and investment value.

Why is the Yen becoming the new favorite among investors?

Hedging currency gaining popularity

The Yen is ranked alongside the USD and Swiss Franc as one of the three major global safe-haven currencies. When geopolitical risks rise, capital floods into the Yen—during the Russia-Ukraine conflict in 2022, the Yen appreciated 8% in a single week, effectively buffering stock market declines. For Taiwanese investors, holding Yen is akin to buying “insurance” against Taiwan stock market volatility.

Reversal opportunity in low-interest arbitrage

The Bank of Japan’s Governor Ueda Kazuo recently signaled a hawkish stance, with market expectations of rate hikes reaching 80%. If the December 19 meeting raises rates by 0.25 bps to 0.75% (a 30-year high), and considering Japanese bond yields have broken a 17-year high of 1.93%, the Yen’s attractiveness will increase again. This suggests the past arbitrage strategy of “borrowing low-interest Yen to invest in high-interest USD” may reverse, with Yen appreciation potential emerging.

Already appreciated 8.7% since the start of the year

By December 2025, the NT$ to JPY rate has risen from 4.46 at the start of the year to 4.85, a total appreciation of 8.7%. For investors already holding Yen assets, the exchange gains are substantial. Meanwhile, Taiwan’s foreign exchange demand increased by 25% in the second half of the year, mainly driven by tourism recovery and institutional hedging needs.

Foreign currency accounts vs. cash withdrawal needs

Before planning your Yen holdings, you need to answer a key question: do I need cash, or is holding in an account sufficient?

Many wonder—Can I deposit NT$ into a foreign currency account? The answer is yes. Most banks’ foreign currency accounts support NT$ transfers, typically free or low-cost. The process is: transfer NT$ from your NT$ account to the foreign currency account (usually free or with minimal fee), then exchange currencies within the account. This offers high flexibility—you can buy in batches at favorable rates or adjust your position anytime.

For example, E.SUN Bank’s foreign currency accounts allow direct transfer from NT$ accounts, then exchange to Yen at the spot rate, with 24-hour availability and lower fees than in-branch.

Four practical currency exchange methods comparison

There are over ten methods circulating for exchanging Yen, but the mainstream channels are actually only four. The key differences lie in exchange rate tiers and time flexibility.

Method 1: In-branch cash exchange—most direct but most expensive

Carry NT$ cash to a bank or airport counter to exchange for Yen cash. This is the “most traditional” way but also the “least cost-effective.”

Banks price based on the “cash selling rate,” which is about 1-2% worse than the spot rate, plus fixed fees. For NT$50,000, total cost loss is about NT$1,500-2,000. For example, Taiwan Bank’s cash selling rate is about 0.2060 NT$/JPY (or 4.85 JPY/NT$). Some banks like E.SUN and Cathay United also charge NT$100-200 handling fee.

The only advantage is safety, full denominations, and no prior appointment needed. Suitable for small, urgent exchanges (e.g., at the airport) or unfamiliar with online banking.

Method 2: Online currency purchase + airport pickup—standard process for planners

No need to open a foreign currency account. Fill in currency, amount, pickup branch, and expected date on the bank’s website. After NT$ deduction, bring ID and transaction notice to the counter for pickup.

Taiwan Bank’s “Easy Purchase” online exchange has no handling fee (pay NT$10 via Taiwan Pay), with about 0.5% better rate, costing NT$300-800. More convenient, with 14 Taiwan Bank branches at Taoyuan Airport, including 2 open 24 hours, ideal for last-minute cash needs before departure.

Lowest time cost but requires at least 1-3 days reservation; branches cannot change appointments on the spot. Suitable for well-planned trips with confirmed departure dates and those wanting to pick up cash at the airport.

Method 3: Online exchange + foreign ATM withdrawal—balance of flexibility and cost

Use bank app or online banking to convert NT$ to Yen and deposit into a foreign currency account (using spot sell rate). Then, use a chip-enabled debit card at foreign ATMs to withdraw cash. Exchange rate advantage of about 1%, but withdrawal incurs exchange spread fees (from NT$100). Cross-bank withdrawal adds NT$5 fee, total cost NT$500-1,000 for NT$50,000.

SinoPac Bank’s foreign currency ATMs allow withdrawal from NT$ accounts, with a daily limit of NT$150,000 and no exchange fee. The main advantage is “batch entry”—you can observe rate trends and buy at low points (e.g., below NT$4.80/JPY), averaging your cost.

Note: Foreign currency ATMs are limited (~200 nationwide). During peak times (e.g., airports), cash may run out. Avoid last-minute rush. By end of 2025, Japanese ATM withdrawal services will shift to international cards (Mastercard/Cirrus).

Suitable for those with forex experience, long-term Yen holdings, or planning to invest in Yen deposits (annual interest 1.5-1.8%).

Method 4: Chip card ATM withdrawal—fastest and most flexible 24/7

Use a chip-enabled debit card at foreign currency ATMs to withdraw Yen cash, available 24 hours. Deduct NT$5 cross-bank fee, no exchange fee, total NT$800-1,200 for NT$50,000.

Disadvantage: denominations are fixed (only 1,000/5,000/10,000 Yen), and locations are sparse. Suitable for busy professionals who need quick, small withdrawals without visiting the bank.

Is now a good time to exchange Yen? Rate trend analysis

Short-term volatility, medium-long-term upward trend

USD/JPY dropped from a high of 160 at the start of the year to 154.58, possibly testing 155 in the short term. But with the BOJ rate hike expectations rising, the medium-long-term forecast points to further strengthening below 150. For Taiwanese investors, the current rate of 4.85 remains relatively high; gradual entry is preferable over a lump sum.

Timing hedging allocations

Against the backdrop of NT$ depreciation pressure and rising global geopolitical risks, holding Yen is no longer just “playing” but “insurance.” It is recommended to allocate 10-20% of assets to Yen, holding long-term to hedge Taiwan stock market volatility.

Investment risk warning

Short-term arbitrage positions may cause 2-5% fluctuations when closed. If aiming for Yen appreciation gains, avoid chasing highs; a phased approach over 3-6 months is more prudent.

Four strategies to increase Yen value after acquisition

Once you have Yen, simply holding it will lead to depreciation. The following four options are suitable for small-scale beginners to gradually upgrade.

1. Yen fixed deposit—steady yield of 1.5-1.8%

Open a foreign currency account at E.SUN or Taiwan Bank, deposit Yen fixed deposit. Minimum NT$10,000 equivalent, interest paid monthly or periodically, no exchange rate risk. Suitable for conservative short-term (1-2 years) capital preservation.

2. Yen insurance—mid-term guaranteed rate of 2-3%

Buy foreign currency savings insurance from Cathay or Fubon Life, with guaranteed rates of 2-3%, usually starting from 5-year terms. Similar risk profile as fixed deposit but higher returns, suitable for medium-term (3-5 years) planning.

3. Yen ETFs (00675U, 00703)—tracking exchange rate movements for growth

For example, Yuanta 00675U tracks Yen index. Can be bought as fractional shares via brokerage apps, suitable for dollar-cost averaging or swing trading. Management fee around 0.4% annually. Higher risk than fixed deposits but potential for currency appreciation.

4. Forex trading USD/JPY or EUR/JPY—advanced short-term play

Trade Yen currency pairs directly on forex platforms. Advantages include long/short positions, 24-hour trading, and small capital requirements (leverage). Suitable for experienced traders aiming to capture short-term swings, but with higher risk.

Final currency exchange tips

Yen has become a staple in global investment portfolios. If your goal is to travel next year, “online exchange + airport pickup” is recommended; for investment purposes, “foreign currency account + fixed deposit or ETFs” is suitable; if pressed for time, foreign ATM withdrawal is the most practical.

The core principles are: batch exchange, diversify risk; don’t just sit on your gains—actively grow your assets. Following these will help lower costs, amplify returns, and provide extra protection amid global market turbulence.
