Korean Won Firms to 1,423.8 per Dollar, Extending Its Advance a Second Day

The Korean won strengthened against the US dollar for a second consecutive session on August 6, with the 15:30 reference rate set at 1,423.8 won per dollar — down 0.7 won from the previous day. The move was a modest follow-through to the sharper appreciation recorded on August 5, when the rate fell 8.0 won to 1,424.5, leaving the currency 8.7 won stronger over the two sessions combined.

A Sharp Move, Then a Pause

The two days tell different stories about momentum. Tuesday’s 8.0-won decline was a decisive one-day repricing of the dollar in Seoul trading, pulling the pair down from the mid-1,430s territory it had occupied beforehand. Wednesday’s 0.7-won dip, by contrast, amounted to consolidation: the market held on to the prior day’s gains rather than extending them meaningfully, with the rate settling just below the 1,424 line.

That pattern — a large adjustment followed by a near-flat session — often indicates that the initial move priced in the available news quickly, leaving little fresh impetus the following day. The won ended the August 6 session at its strongest reference level of the two-day stretch.

Why the 15:30 Rate Matters

The 1,423.8 figure is the market average rate fixed at 15:30 in Seoul, the benchmark that anchors the close of the main onshore trading session. Banks, corporates, and the customs authority use this reference for settlement and accounting purposes, which makes it the standard yardstick for tracking the won’s day-to-day direction even though onshore trading now runs into the night.

For importers, a firmer won at the fix directly lowers the cost of dollar-invoiced purchases; for exporters, the same move trims the won value of overseas earnings. A sustained hold below the mid-1,420s would mark a meaningful improvement from the weaker levels that had prevailed earlier, though two sessions of appreciation are not by themselves evidence of a durable trend.

The next reference point comes at Thursday’s 15:30 fix, which will show whether the won can build on its 1,423.8 close or whether the dollar reclaims the ground it gave up this week.
