Is now the right time to exchange Japanese Yen? A comprehensive analysis of the top 5 channels' costs and investment opportunities

Yen Appreciation by 8.7%, Exchange Window Opening

As of December 2025, the NT dollar to Japanese Yen exchange rate has risen to 4.85, compared to 4.46 at the beginning of the year, representing an 8.7% appreciation of the Yen over the year. Many are starting to consider: Is it a good time to exchange for Yen now? The answer is yes, but with conditions.

The Bank of Japan (BOJ) recently signaled a hawkish stance, with market expectations of a rate hike to 0.75% in December (a 30-year high), and Japanese government bond yields reaching a 17-year high of 1.93%. Meanwhile, the USD/JPY has fallen from a high of 160 at the start of the year to around 154.58, indicating potential medium- to long-term upside for the Yen. For Taiwanese investors, Yen is not just cash for travel but also a hedging asset against Taiwan stock market volatility.

Why is the Yen Worth Watching? Three Key Perspectives

Daily Use: Travel, Shopping, Study Abroad Needs

Japan remains a global consumption hotspot, with cash still dominant. Whether shopping in Tokyo, skiing in Hokkaido, or vacationing in Okinawa, most merchants rely on cash transactions (credit card penetration is only 60%). Besides travel, consumers who enjoy Japanese cosmetics, fashion, and anime merchandise often need to pay directly in Yen, and students or working holidaymakers will exchange currency in advance to lock in exchange rates.

Global Hedging Asset: Alongside USD and CHF

The Yen has long been regarded as one of the world’s three major safe-haven currencies. Japan’s stable economy and low government debt make Yen a safe haven during market turbulence. For example, during the Russia-Ukraine conflict in 2022, the Yen appreciated 8% in a week, effectively buffering a 10% stock market decline. For Taiwanese investors, exchanging for Yen adds a “risk firewall” in their asset allocation.

Arbitrage and Interest Rate Advantage: Low Financing Costs Investment Tool

Japan’s ultra-low interest rate policy (just 0.5%) makes Yen a global “funding currency.” Savvy investors borrow Yen at low interest and convert to higher-yield USD investments, with a USD/JPY interest rate spread of up to 4.0%, creating arbitrage opportunities. When risks rise, they close positions by buying back Yen, further strengthening the Yen.

Five Main Channels for Yen Exchange: Cost and Convenience Comparison

Option 1: Bank Counter Cash Exchange — Most Traditional but Highest Cost

Carry NT dollars in cash to a bank or airport to exchange for Yen cash. Advantages are safety, full denominations, and immediate receipt. However, banks use “cash selling rates” (1-2% worse than spot rate), plus possible fees, making this the most expensive option.

Based on December 2025 rates, the cash selling rate at banks is approximately 0.2058-0.2069 NT$/Yen (about 4.85-4.87 Yen per NT$). Some banks charge an additional 100-200 NT$ fee. For 50,000 NT$, the total loss is about 1,500-2,000 NT$.

Suitable for: Urgent needs, small amounts, travelers unfamiliar with online options.

Option 2: Online Currency Exchange for Airport Pickup — Best for Planned Travel

Fill in currency and amount online via bank website, select pickup branch, complete transfer, then present ID and transaction notice to pick up cash at the branch. Some banks offer this service fee-free (e.g., only 10 NT$ with certain e-payments), with exchange rate advantage of about 0.5%.

The biggest advantage is booking ahead for airport pickup, avoiding the hassle of city bank visits. Major airport branches have 14 locations, with 2 open 24 hours, suitable for last-minute exchange before departure. For 50,000 NT$, the cost difference is only 300-800 NT$.

Suitable for: Well-planned travelers, those who plan ahead, and want to pick up cash at the airport.

Option 3: Online Currency Conversion to Foreign Currency Account — Long-term Holders and Investors’ Choice

No cash withdrawal needed; transfer NT$ to Yen directly in bank app into a foreign currency account, using “spot sell rate” (about 1% better than cash rate). If cash is needed later, withdraw at counter or ATM, with additional withdrawal fee (starting at 100 NT$).

Ideal for monitoring exchange rates and gradual entry. For example, buy in tranches when NT$/Yen drops below 4.80 for lower average cost. Once the Yen is in the foreign currency account, it can be further placed into fixed deposits (current annual interest 1.5-1.8%) or invested in Yen ETFs, achieving “exchange and grow” goals. For 50,000 NT$, the potential loss is 500-1,000 NT$.

Suitable for: Experienced forex users, those who frequently use foreign currency accounts, and investors seeking to combine exchange with investment.

Option 4: Foreign Currency ATM Withdrawal — 24/7 Instant Cash

Use a chip-enabled bank card at foreign currency ATMs to withdraw Yen cash, operational 24/7 with low cross-bank fee (only 5 NT$). Deducted directly from NT$ account, no exchange fee.

Limited ATM locations (about 200 nationwide) and currency options, mainly major currencies. Denominations are fixed at 1,000, 5,000, 10,000 Yen, with daily/transaction limits varying by bank (usually 100,000-150,000 NT$). During peak times like airports, cash may run out. Plan ahead to avoid last-minute issues. For 50,000 NT$, the cost is about 800-1,200 NT$.

Suitable for: Busy professionals with no time to visit branches, urgent cash needs, convenience seekers.

Option 5: Multi-Channel Mix — Best for Budget of 5-20万 NT$

For a budget between 5-20万 NT$, the optimal approach is a hybrid: “Online currency exchange (airport pickup) + foreign currency ATM.” First, exchange a main amount (e.g., 3-5万 NT$) online for pickup, then use ATM for small additional needs. This balances favorable rates with flexibility, optimizing costs.

Best Timing and Strategy for Exchanging Yen Now

Exchange Rate Trend Analysis: Opportunities Amid Volatility

USD/JPY has fallen from 160 to 154.58, with short-term support around 155, and medium- to long-term forecast below 150. BOJ rate hikes will continue to support Yen, and amid global economic slowdown, Yen’s safe-haven appeal rises.

In the second half of the year, Taiwan’s currency exchange demand increased by 25%, mainly driven by travel recovery and hedging needs, reflecting investor confidence in Yen.

Strategy Advice: Gradual Entry, Avoid Chasing High

Although Yen’s upward trend is clear, short-term arbitrage closing may cause 2-5% fluctuations. The safest approach is to exchange in tranches rather than all at once. For example:

• First batch: when NT$/Yen is below 4.82, exchange 40%
• Second batch: below 4.85, exchange 35%
• Remaining 25% as flexible reserve

This method averages costs and mitigates sudden exchange rate swings.

Post-Exchange Asset Growth Strategies

Yen should not be held passively without earning interest. Based on investment goals and risk appetite, here are four options:

Yen Fixed Deposit (Conservative): Transfer Yen into a bank foreign currency account and deposit, starting from 10,000 Yen, with annual interest of 1.5-1.8%, risk-free. Suitable for conservative investors.

Yen Savings Insurance (Mid-term): Yen-denominated insurance policies from life insurers, with guaranteed interest rates of 2-3%, combining protection and returns. Suitable for 3-5 year planning.

Yen ETFs (Growth): For example, Yuanta 00675U (tracking Yen index), purchasable in fractional shares via broker app, supporting dollar-cost averaging. Management fee 0.4% annually, suitable for long-term asset allocation.

Yen Forex Trading (Swing Trading): Direct trading of USD/JPY or other currency pairs to capture short-term fluctuations. Both long and short positions, 24-hour trading, but requires experience and risk management.

Yen vs. Australian Dollar: New Comparison of Hedging Assets

In hedging asset choices, AUD and JPY each have features. Yen is a traditional safe-haven currency, attracting capital during crises; AUD, with high interest and commodity currency traits, performs well during economic booms. Diversifying between both can further reduce risk—Yen for defense, AUD for growth. Currently, AUD/NT$ is around 21-22, with different investment logic from Yen, worth further attention.

Summary: Yen is More Than Travel Money, a Must-Have Asset Allocation

Yen has evolved from “travel pocket money” to a dual-function asset for hedging and appreciation. Whether you’re a traveler planning a trip to Japan next year or an investor hedging against NT$ depreciation, the key is the “tranche exchange + growth after exchange” principle.

This not only makes travel more cost-effective but also adds a layer of protection amid global market turbulence. Start planning now to turn your NT$ into smarter assets.
