What moves the USD/KRW rate
The dollar-won rate floats, so it shifts with the gap between U.S. Federal Reserve and Bank of Korea policy rates, the broad strength of the dollar (the DXY index), and Korea's export cycle — semiconductors and cars bring dollars in. The won is also risk-sensitive: when global markets turn defensive, foreign investors pull money out of Korean stocks and the won weakens, pushing the number of won per dollar higher. So a "rising exchange rate" here means a weaker won.
Reading the number: won per dollar
USD/KRW is quoted per single dollar, so "1,380" means one dollar buys about 1,380 won — no dividing by 100 the way you would with the Japanese yen, which is usually shown per 100 yen. Two quick examples at 1,380: a $50 Amazon order is 50 × 1,380 = 69,000 won, while a 1,000,000-won budget is 1,000,000 ÷ 1,380 ≈ 724 dollars. Multiply going one way, divide going the other.
Live mid-market vs. bank and card rates
This tool uses the Korea Eximbank base rate — the mid-market reference rate that no one actually trades at. Banks, airport booths, and card networks add a spread and fees on top, so a wire transfer for tuition, a cash exchange for travel, or an overseas card purchase for direct shopping will cost a bit more won per dollar than the figure here. Use this as your baseline.
Frequently asked questions
Is this the rate my bank will actually give me?
No. The tool shows the mid-market rate. Banks quote a telegraphic-transfer or cash-selling rate that adds a spread on top, and cash exchange carries the widest spread of all. At an airport counter especially, expect to pay noticeably more won per dollar than the figure shown here.
What will my card really charge for a US purchase?
For an overseas card payment, Visa or Mastercard convert at their own rate (close to mid-market), then add roughly a 1% network fee plus your issuer's foreign-transaction fee. And it is applied at the settlement date's rate — not the exact moment you click buy — so the billed amount can drift slightly.
How often does the rate update?
Korea Eximbank publishes its base rate once per business day, around 11 a.m. Korea time, so the figure holds over weekends and holidays until the next update, and the reference date is shown on screen. If you need minute-by-minute trading quotes, you would need a dedicated live market-data feed instead.
