Korea's June-to-August surpluses add up to more than its record 2025 total

Add June's $49.73 billion ^[1], July's $42.08 billion and August's $46.11 billion ^[2], and Korea has earned $137.92 billion on its current account in three months ^[17]. All of 2025, the best year on record, brought in $123.05 billion ^[9]. Yonhap put the gain over August 2025 at $36.2 billion ^[8], so last August's surplus was about $9.9 billion ^[18]. On the export side, 82.1% growth to $104.8 billion implies roughly $57.6 billion shipped a year earlier ^[19], close to what Korea imported this August ^[5].

August's improvement on July came from goods. The goods surplus widened $6.38 billion on the month ^[6], while the total rose $4.03 billion ^[2]. Primary income fell to $1.92 billion from $4.35 billion ^[23]. Quarterly dividend payments on portfolio investment were concentrated in August, Sedaily reported, cutting the dividend income surplus to $1.18 billion from $3.83 billion ^[23]. The services deficit narrowed slightly, to $1.68 billion from $1.97 billion ^[7].

The 82.1% is the growth in all goods exports ^[5]. Semiconductors alone rose 206.1% on a customs basis, and information and communication equipment 137.4% ^[3]. By destination, exports to China rose 119.4%, to Southeast Asia 91.7% and to the U.S. 89.2% ^[10]. Growth in exports to the European Union went the other way, slowing to 14.6% in August from 56.1% in July ^[11].

The next few releases can go about three ways. Chip shipments hold near this level and the surplus stays above $40 billion. Chips hold while the rest of the export book shrinks further, though with passenger cars already down 30.1% and ships 45.2% ^[12], there is little outside IT left to lose. Or chip growth cools the way EU growth did between July and August, and the total follows it down.

I'd expect the first through the autumn. Three straight months above $40 billion ^[4] are harder to explain as a one-off shipment than as a cycle, and chip exports at about 3.1 times last year's level ^[14] are the reason. The counter-case sits in the same release: a surplus this dependent on one product has no second earner if chip demand turns. A September surplus back under $40 billion would show the view wrong. The reported figures do not include an exchange rate, chipmaker earnings or a split of the chip gain between price and volume.

For the won, the surplus is only the inbound half of the flow. Dollars come in through exports, and the currency moves on what residents then do with them. In August they put a record $6.44 billion into overseas debt securities, above the previous high of $6.31 billion set in May last year ^[16].
