South Korea's chip export boom turns into a fall
The test The trade ministry's monthly export releases published between 1 Nov 2026 and 31 Oct 2027 show South Korea's semiconductor exports lower than in the same month a year earlier for three months in a row.

What changed
Dated, newest first
- Chip exports US$113.89bn in Q2 2026 (+181.6%) and US$148.02bn in Q3 (+218.7%); Q2 current-account surplus US$116.6bn against US$28.4bn a year earlier; IMF about US$422bn for 2026, US$177.5bn by 2031 [1]
- Oct 1-20 chip exports US$27.5bn (+222.5%), 44.7% of exports; total US$61.6bn [2]
- 13 working days, 2.5 more than a year earlier (Chuseok); per working day +65.9%; DDR5 16Gb US$48 in Sep from US$46.50 in Aug [3]
Why it matters
South Korea's chip exports reached US$148.02bn in the third quarter of 2026, up 218.7% on a year, and its second-quarter current-account surplus of US$116.6bn was larger than Germany's and Japan's together. In the first 20 days of October chips were 44.7% of all exports. TrendForce expects DRAM supply to stay tight in 2027. The risk is that the cycle turns and chip exports fall below the year before for three months in a row.
Why Likelihood 3 Pushes: NAND loosening in 2H27, warnings on AI investment and the US midterms, the 15-month 2022-23 run. Brakes: TrendForce expects DRAM tighter in 2027 with prices rising.
Why Impact 5 Threshold case three months of small year-on-year falls. Key price DRAM contract prices.
The other facts on file (5)
- 2025 chip exports US$173.4bn (+22.2%); total exports US$709.7bn [4] (2 Jan 2026)
- October 2023 chip exports US$8.9bn, -3.1%, smallest drop since August 2022 [5] (1 Nov 2023)
- November 2023 chip exports +12.9%, ending 15 months of declines [6] (30 Nov 2023)
- TrendForce: DRAM supply tight in 2027, prices rising; NAND looser and prices pressured in 2H27 [7] (30 Jul 2026)
- Taiwan imported US$63.7bn from South Korea in 2025 (+45.7%) [8] (23 Feb 2026)
Where it sits
How it spreads
The trade ministry's monthly export releases published between 1 Nov 2026 and 31 Oct 2027 show South Korea's semiconductor exports lower than in the same month a year earlier for three months in a row.
Not under wayChannels 4 on the card
- CanadaSouth Korea took 46 of 122 Kitimat LNG cargo records (Strature calculation) [10] and was projected to import 16 million barrels of Canadian crude in 2026 [9]; no loss from a chip turn sourced.
- Growth and the wonChips were 44.7% of exports in 1-20 October [2] and 24.4% in 2025 (Strature calculation) [4], so a turn would cut the surplus the IMF expects to peak in 2026 [1].
- TaiwanTaiwan imported US$63.7bn from South Korea in 2025 [8]; a memory turn hits both economies at once.
- US trade pressureA falling surplus with the US would ease trade pressure.

Three scenarios and their signposts
- S1
Tight to the end
DRAM stays short through 2027 and exports keep rising year on year.
- S2
A NAND-led slowdown
NAND prices fall in 2H27 and growth slows sharply but stays above zero.
- S3
The cycle turns
Cloud spending is cut and DRAM prices fall; chip exports drop below 2026 levels.
| Path | Signpost |
|---|---|
| S1 | Monthly chip export growth stays positive |
| S2 | Monthly chip export growth below 10% |
| S3 | A quarter-on-quarter fall in DRAM contract prices reported by TrendForce |
No probability is given for the three paths.

The other side
A turn would also ease the record surplus with the US that could renew trade pressure, and would free memory supply for buyers who face higher prices; TrendForce expects smartphone and notebook demand to fall in 2027 because of component costs [7].
