Korea's trade and output improved, but firm U.S. yields still challenge the won.
The won is balancing Korea's export momentum against a still-firm U.S. dollar backdrop.
The sections below walk through how each case reads the same frozen evidence, with the stored readings and charts alongside.

For Korea customs exports, the Jun 2026 stored reading is about 102.2 billion U.S. dollars; the gap from the first stored month is +36.3 billion U.S. dollars.
The last stored reading for Korea customs imports is about 66.1 billion U.S. dollars (Jun 2026), a change of +9.7 billion U.S. dollars from the first stored month.
As of Apr 2026, Korea real GDP, seasonally adjusted stands at about 600.4 trillion Korean won in the stored series, +14.4 trillion Korean won from the first stored month.
Frozen data show the won firming while Korea's surplus, trade, and output improved. Those flows can increase demand for won assets and offset the dollar's yield edge. If that channel holds, the dollar buys fewer won by the evaluation date.

As of Jul 2026, U.S. consumer prices stands at an index level of 332.813 (1982–84=100) in the stored series, +8.568 points from the first stored month.
U.S. 7-year Treasury auction ($99.928654) is filed among this case's supporting evidence.
The last stored reading for U.S. nominal GDP is about 32.5 trillion U.S. dollars (Apr 2026), a change of +1.1 trillion U.S. dollars from the first stored month.
Frozen data also show firm U.S. rates, rising prices, bigger output, and a high Treasury auction yield. That mix can keep dollar carry attractive and blunt Korea's trade support. If it dominates, the dollar buys more won by the evaluation date.
03 · Hypothetical result to testBy 2026-09-30, KRW per USD closes above 1372.5.
