Why exchange yen now? Dual appeal of hedging + returns

The yen is not only essential for travel but also one of the world’s three major safe-haven currencies (alongside the US dollar and Swiss franc).

Meanwhile, as a financing currency, the USD/JPY interest rate differential is as high as 4.0%, with many investors borrowing yen to buy USD assets for arbitrage.

Everyday use: Traveling to Japan, shopping, purchasing on behalf, studying abroad all require cash yen (Japan cash usage still reaches 60%), plus long-term yen preservation, small holdings pose no loss risk.

Exchange rate trend: From 4.46 at the start of the year to 4.85 now, an appreciation of 8.7%. With the NT dollar depreciating, holding yen has become an option for asset protection.

Is it cost-effective to exchange yen now? Rate analysis + timing

The NT$/JPY rate is currently 4.85, up 8.7% from 4.46 at the start of the year, showing significant exchange gains. Meanwhile, with USD/NT$ at 32.5, the US-Japan interest rate differential remains loose, supporting the yen in the short term.

Market observations:

• BOJ rate hike expectations heating up (expected to rise to 0.75% at December 19 meeting)
• USD/JPY dropped from 160 high to 154.58, short-term volatility may bring it back to 155
• Medium-long term forecast below 150, yen remains strong

Investment suggestions:

• Travel: Exchange now isn’t too expensive, staggered entry to reduce risk
• Hedging: Yen as a major safe-haven currency, suitable for hedging Taiwan stock volatility, recommend staged entry (avoid all at once)
• Short-term trading: Arbitrage closing risks, expected fluctuation 2-5%, set stop-loss

Staged operation principle: exchange 1/3 or 1/4 weekly, average rate, avoid chasing highs or over-concentrating risk.

After exchanging yen, don’t let your money sit idle

Once you’ve completed the exchange, you can transfer yen into income-generating channels:

Yen fixed deposit: Most stable option, open online with E.SUN or Taiwan Bank, minimum 10,000 yen, annual interest 1.5-1.8%.

Yen insurance policy: Cathay, Fubon savings insurance, guaranteed interest 2-3%, suitable for 3-5 year medium-term holding.

Yen ETFs: such as Yuanta 00675U (tracking yen index), 00703, can buy fractional shares, management fee 0.4% annually, suitable for growth investors.

Forex swing trading: directly trade USD/JPY, EUR/JPY pairs, capture short-term volatility, both long and short, 24/7 trading, requires technical analysis skills.

Although yen is a safe-haven, global arbitrage closing or geopolitical risks (Taiwan Strait, Middle East) may temporarily depress it. For non-expert traders, a combination of yen fixed deposits + small ETFs is the safest.
