Market rate · 23 October 2026
1 USD = 1,325.29 KRW
Mid-market spot. Banks and exchange houses pay less than this.
Against its own recent history, one US Dollar is 7.7% weaker against the South Korean Won than it was a year ago, and 12.6% stronger than five years ago. Across ten years it is 16.7% stronger.
A rising number means one US Dollar buys more South Korean Won than before. Which direction is good news depends entirely on which way you are converting.
Averaged over the last 10 years, USD moved 5.4% against South Korean Won in a typical year — a normal amount of movement for a major pair, though enough to notice on a large transfer. Its strongest year returned +21.4% and its weakest -7.7%.
Right now it sits 15.7% below its all-time high and 49.5% above its all-time low.

Each row is the rate on the same calendar date in that year, carried forward from the last trading day where markets were closed.
Every figure on this page is the mid-market rate: the midpoint of the wholesale market, and a price no retail customer is offered. Banks, card networks and remittance services quote you a rate below it and keep the difference. On a typical transfer that gap runs from well under 1% for the sharpest providers to 4% or more for an airport counter, and it is often the entire cost of the transaction even where the fee is advertised as zero.
The converter has a what-if box for exactly this. Enter the rate you were quoted and it shows the gap as a percentage and as an amount in South Korean Won — which is usually a more sobering number than the percentage suggests.
Google shows an intraday quote that moves throughout the day. This page uses the daily close. A fraction of a percent between them is normal, and neither is wrong.
Yes — that is the point of the site. Open the converter, enter your amount, and set the date. It reaches back to 1 December 2003 for this pair.
Whichever rate your tax authority or accounting standard specifies, on the date the transaction occurred. Most require the official or closing rate for that day, not today's rate.
