The Won Just Hit a 10-Month High — Seoul's Weak-Currency Discount Is Nearly Gone
August 21, 2026
On 19 August, the Korean won broke back below 1,400 to the US dollar for the first time in ten and a half months, trading around 1,399 by midday in Seoul — a sharp reversal from the 1,540.55 low it hit on 4 June, its weakest level since March 2009. For Hong Kong travellers who've spent the summer hearing "book Seoul now while it's cheap," the currency half of that pitch just got noticeably less true.
The math that changed in ten weeks
At June's low, HK$1,000 (the Hong Kong dollar is pegged near 7.80 to the US dollar) bought roughly 197,500 won. At Wednesday's rate, the same HK$1,000 buys about 179,400 won — 9.2% less. Flip it around: a 200,000-won hotel room that cost HK$1,013 a night in June now costs HK$1,115, an extra HK$102 a night, or roughly HK$408 across a four-night stay before you've even touched flights. None of the underlying reasons Seoul got cheap — the won's stock-outflow-driven slide through most of 2026 — reversed overnight; this is a genuine, dated swing, not noise.
Hotels didn't wait for the currency to catch up
The exchange rate would sting less if Seoul room rates had stayed flat. They haven't. First-half 2026 foreign arrivals hit a record 10.71 million, up 21.3% year on year, and K-culture-driven demand has pushed some Seoul luxury hotels past 1 million won a night — over HK$5,570 at today's rate — with operators upgrading and rebranding rooms to chase that spend. Budget and mid-range Seoul stays haven't seen the same spike, but the room-rate cushion that used to offset a strong won is thinner than it was even a month ago, when Korean Air's takeover of Asiana added its own separate pressure on Hong Kong–Seoul fares.
Is Seoul still worth booking now?
Yes, with the caveat that the deal has quietly gotten smaller. A HK$1,000 Seoul weekend that priced out well against the won's June low is now roughly one meal or one day's subway pass worse off — not enough to cancel a trip, but enough that "the weak won will cover it" is no longer a safe assumption to build a budget on. Lock in hotel rates now if Seoul is on your autumn list: between a strengthening won and record-high arrivals squeezing rooms, the version of this trip that was cheap in June is not the version you'll get in October.
