Won Breaks Into 1,330 Range Against Dollar for First Time in 23 Months

The Korean won pushed to its strongest level against the U.S. dollar in nearly two years on September 9, with the 3:30 p.m. benchmark rate in Seoul set at 1,336.1 won per dollar — down 9.5 won from the previous session and the first reading in the 1,330 range in 23 months, a threshold last seen around October 2024.

Three Sessions, One Direction — With a Detour

The move capped a choppy stretch for the onshore market’s daily reference rate. On September 7, the benchmark dropped 9.9 won to 1,340.5. It then gave part of that back on September 8, rising 5.1 won to 1,345.6, before the September 9 decline carried it decisively below the 1,340 line.

Taken together, the three fixings put the rate 14.3 won below its implied level of 1,350.4 at the end of the prior week — a won appreciation of roughly 1.1% in three trading days. The September 9 move alone amounted to a 0.7% single-day gain for the Korean currency.

Why the 1,330 Handle Matters

Round-number thresholds in the won-dollar rate carry outsized weight for Korean exporters, importers, and anyone pricing dollar-denominated liabilities, and this one had held for nearly two years. A lower rate means each dollar buys fewer won: relief for fuel and raw-material importers and for households facing dollar-priced costs, but a squeeze on the won value of exporters’ dollar revenues.

The pattern of the past three sessions also shows the decline was not a straight line. The 5.1-won rebound on September 8 was more than erased the following day, leaving the rate at its lowest benchmark level of the period despite the intervening bounce — a sign that dollar-selling pressure reasserted itself quickly after the pause.

Where the rate settles from here will determine whether the 1,330 range marks a brief undershoot or a new operating band for the currency. The next daily fixings will show whether the two-year threshold holds as a floor or gives way further.
