USD to CNY, JPY and KRW: What Actually Moves East Asian Currencies (2026)

Analysis · November 3, 2026 · 12 min read · By GlobalFxcc Data Desk · Data checked 3 November 2026

Short answer: the yuan, yen and won are three different machines. The yuan is managed by the People's Bank of China, the yen floats freely and is driven by interest-rate gaps, and the won floats but reacts hard to global risk and semiconductor exports. A 1% move in the dollar produces different outcomes in each - and different costs for anyone sending money home from Tokyo, Seoul or Shanghai.

1. Three currencies, three regimes

Currency	Regime	Who sets the tone	Typical daily move
CNY (yuan)	Managed float, +/-2% band around a daily fixing	People's Bank of China, trade flows, capital controls	Small - the fixing anchors it
JPY (yen)	Free float, occasional official intervention	Bank of Japan policy, US-Japan rate gap, safe-haven flows	Moderate to large
KRW (won)	Free float	Bank of Korea, exports, foreign portfolio flows, risk appetite	Moderate, spikes in stress

Current mid-market levels on 3 November 2026: USD/JPY 157.90, USD/CNY 6.67, USD/KRW 1,344.13. Live pages: USD to JPY, USD to CNY, USD to KRW.

2. What moves the yuan

The PBOC publishes a daily reference rate each morning in Beijing. The onshore rate can trade within a 2% band around that fixing, so the fixing is the single most important number of the day. Around it, three forces matter:

Trade surplus: exporters converting dollars into yuan create steady demand for the currency.
Rate differential: when US yields are much higher than Chinese yields, capital tends to leave, which pulls the yuan weaker.
Policy: capital controls and state-bank dollar sales can slow a move that the market would otherwise push further.

Practical effect for senders: CNY crosses often gap at the Beijing fixing (around 09:15 local time) rather than moving smoothly through the day. If you are sending from China, the fixing can matter more than the hour you press send.

3. What moves the yen

The yen is the cleanest free float in the group, and the dominant driver is the US-Japan interest-rate gap. When US yields rise faster than Japanese yields, money moves out of yen and USD/JPY rises. When the gap narrows - because the Bank of Japan hikes or the Fed cuts - the yen usually strengthens.

Bank of Japan policy: even small changes in the policy rate or bond-buying move the yen sharply.
Safe-haven flows: in a global risk-off move, the yen tends to strengthen regardless of rates.
Energy imports: Japan imports most of its energy, so higher oil prices worsen the trade balance and can weaken the yen.
Intervention: the Ministry of Finance has stepped in when moves were judged excessive. It slows a trend, it does not reverse it.

For a sender in Japan, USD/JPY is only half the story. What matters is JPY to PHP or JPY to VND - the yen's move against the dollar plus the peso's or dong's own move.

4. What moves the won

The won is a free float with a strong cyclical character. It typically weakens when global investors sell risk assets and strengthens when semiconductor exports and foreign equity inflows are strong.

Semiconductor cycle: chips are a large share of Korean exports, so the sector's outlook moves the won.
Foreign portfolio flows: Korea is a large, liquid market for global funds; inflows and outflows show up quickly in USD/KRW.
Bank of Korea: rate decisions and verbal intervention matter, especially near round numbers.
Global risk: in a sharp risk-off week the won often weakens faster than the yen.

For senders in Korea, the practical pair is KRW to PHP or KRW to VND. USD/KRW sets the direction; the provider's margin sets the cost.

5. Remittance maths for East Asia

These are worked examples at mid-market rates on 3 November 2026: JPY/PHP 0.4017, KRW/PHP 0.0472, CNY/PHP 9.5097. A "good" provider here means a 0.8-1% margin and a small fee; a "poor" one means a 2.5% margin and a larger fee.

Send	Mid-market value	Good provider	Poor provider	Difference
JPY 50,000 to PHP	20,085 PHP	19,685 PHP	19,270 PHP	415 PHP (2.1%)
KRW 500,000 to PHP	23,600 PHP	23,271 PHP	22,780 PHP	491 PHP (2.1%)
CNY 5,000 to PHP	47,549 PHP	46,885 PHP	46,082 PHP	803 PHP (1.7%)

The pattern is consistent: on a typical monthly transfer, the gap between a good and a poor provider is about 1.5-2.5% of the amount. On JPY 50,000 that is roughly one week of groceries in the Philippines. Over a year, it is more than a month's worth of transfers.

6. When to send: practical timing

CNY: watch the Beijing fixing. A big gap between the fixing and the previous close often sets the tone for the day.
JPY: the Tokyo morning is usually calmer; the biggest moves come in the London and New York sessions, especially around US data releases.
KRW: avoid sending during global risk-off days; the won can move 1% or more in a session.
All three: avoid Friday after the New York close and the first working day after a long holiday. Payouts can be delayed and rates carry a weekend buffer.

7. What to check before you send

The final amount the recipient gets, in local currency.
Your implied rate = amount received divided by amount sent.
The gap from the mid-market rate on the pair page. Under 1% is good; over 2.5% is expensive.
Whether the payout is to a bank account, wallet or cash, and what limits apply.
Whether the provider is licensed in Japan, Korea or China and in the recipient's country.
