Korea's August Chip Exports Hit a Record $46.7B. Volume Moved Too
Korea's semiconductor exports reached $46.65 billion in August, up 209.0% from a year earlier and 13.8% above July, according to the Ministry of Trade, Industry and Energy's August trade report released September 1. It is a new all-time monthly high, taking out June's $44.81 billion after a one-month dip. The number everyone will quote is the 209%. The number I think matters more is the 13.8%, because contract prices for commodity memory rose only 1% to 4% in August. For the first time this cycle, volume and mix did most of the month-on-month work.
KEY TAKEAWAYS
1. Chip exports hit a record $46.65 billion in August (+209.0% YoY, +13.8% MoM) and now make up 47.5% of all Korean exports, versus 25.9% a year ago.
2. August's month-on-month gain outran price. DDR4 8Gb contract prices rose 4.2%, DDR5 16Gb 3.3%, NAND 128Gb 1.4%. An implied volume/mix index (Jan = 100) moved from 96 in July to 105 in August.
3. The growth is memory, not logic. Memory chips were $40.94 billion (+290.2%), 87.8% of the chip total. Logic was $5.13 billion (+24.4%). SSDs, counted under "computers," were $5.98 billion (+479.5%).
The headline numbers, and two things to read carefully
Total exports were $98.25 billion (+68.7%), the third-highest month on record. Non-semiconductor exports grew 19.5% to $51.60 billion, so the rest of the economy is not standing still, but the gap is enormous. The trade surplus was $34.75 billion for the month and $202.51 billion for January through August, already more than double the previous full-year record of $95.2 billion set in 2017.
| Item | Aug 2026 | YoY | Note |
|---|---|---|---|
| Semiconductors | $46.65bn | +209.0% | +13.8% vs July's $41.01bn |
| Memory | $40.94bn | +290.2% | 87.8% of chips (69.5% a year ago) |
| Logic / system | $5.13bn | +24.4% | 11.0% of chips |
| MCP (within chips) | $12.23bn | +165.5% | Below June's $12.68bn |
| Computers | $6.24bn | +419.5% | Record; 11th straight positive month |
| SSD | $5.98bn | +479.5% | 95.8% of the computer line |
| Chip equipment imports | $2.57bn | +117.3% | Largest gain among non-energy imports |
Two reading notes. First, this "record" is an absolute one. Last month I pointed out that most "record" headlines in Korean trade data mean "record for that calendar month." August is different: $46.65 billion is the highest figure in any month, ever. Second, the ministry's regional breakdown by product covers only August 1-25, with the last six days missing. Every regional figure below is flagged as a 1-25 preliminary and should not be added to or compared against the full-month totals. Korea Customs publishes the final August data around September 15.
Price explains less of the gain than it did in July
TrendForce's DRAMeXchange contract prices for August: DDR4 8Gb at $25.00 (+4.2% MoM), DDR5 16Gb at $46.50 (+3.3%), NAND 128Gb MLC at $30.48 (+1.4%). In July those monthly gains were +14.3%, +12.5% and +4.3%. Price momentum roughly quartered. Yet chip export value rose 13.8% over the same month. Price accounts for a low single-digit share of that; the remaining ten points or so came from shipment volume and product mix.
Using the same method as last month, with January set to 100, August export value indexes at 227 and the DDR4 8Gb contract price at 217. Dividing one by the other gives an implied volume/mix index of 105, up from 96 in July. Korea Customs' August 1-20 data pointed the same way: DRAM export value per kilogram fell 8.0% month-on-month while DRAM export value rose 11.8%.
Why this matters: when contract price growth slows to single digits and export value still grows double digits, the next leg of the export line depends on shipments rather than price. Whether volume holds up as prices flatten is the central question for the back half of a memory cycle, and August is the first month this year where the data says volume is carrying weight.
The second half of August ran faster than the first
Korea Customs reported $26.03 billion of chip exports for August 1-20. Subtracting that from the monthly $46.65 billion leaves $20.62 billion for August 21-31. Per working day, that is $1.86 billion in the first stretch and $2.58 billion in the second. Month-end loading is a permanent feature of Korean trade statistics, so the acceleration itself is not the signal. In July the second-half daily rate was also about 1.5x the first-half rate. What matters is that both halves of August ran above July: roughly 30% higher in the first stretch and 16% higher in the second. The preliminary trend held, and the month finished stronger than it started.
| Window | Chip exports | Working days | Per day |
|---|---|---|---|
| Jul 1-20 | $22.11bn | 15.5 (est.) | $1.43bn |
| Jul 21-31 | $18.89bn | 8.5 (est.) | $2.22bn |
| Aug 1-20 | $26.03bn | 14.0 | $1.86bn |
| Aug 21-31 | $20.62bn | 8.0 | $2.58bn |
The 21-31 figures and July working-day counts are back-calculated from published monthly and 20-day statistics and will shift when Korea Customs finalizes the month.
It is a memory story, and increasingly an SSD story
Split the $46.65 billion and memory is $40.94 billion (+290.2%), logic $5.13 billion (+24.4%). Memory's share of Korean chip exports went from 69.5% to 87.8% in twelve months. Logic grew, but its $1.0 billion increase is about one-thirtieth of memory's $30.45 billion. For practical purposes Korea's semiconductor export line is now a memory line.
Inside memory the signals diverge. MCPs, the multi-chip packages that go into phones, were $12.23 billion (+165.5%) but stayed below June's $12.68 billion. SSDs, reported under "computers," were $5.98 billion (+479.5%), a record and above June's $5.16 billion. NAND contract prices have risen for 20 straight months but added only 1.4% in August, so a 32.5% month-on-month jump in SSD export value is a volume statement about enterprise drives, not a price one.
The destination data sharpens that. In the August 1-25 window, exports to the US were $3.22 billion for semiconductors (+299.7%) and $2.93 billion for computers (+1,040.3%). To the US, finished SSDs are nearly as large as bare chips. AI-server storage is crossing the border as a finished product, which is the same read I had from the July numbers.
China takes 38%, and the China trade balance flipped
Of the $35.48 billion of chip exports in August 1-25, China took $13.44 billion (37.9%, +319.6%), ASEAN $8.12 billion (22.9%, +200.4%) and the US $3.22 billion (9.1%). The regions with a published product split add up to $26.78 billion; the remaining $8.70 billion went to destinations without one, chiefly Hong Kong and Taiwan. Total exports to Hong Kong in the same window were $5.56 billion, up 298.2%, which is not a growth rate you get without chips. China plus Hong Kong is realistically around half, and Hong Kong transshipment continues to blur the true end market.
One macro consequence is worth flagging. Korea's trade balance with China was a $8.8 billion surplus in August. For all of 2025 it was a $11.2 billion deficit. January through August 2026 it is a $27.7 billion surplus. A single product category changed the sign of the bilateral balance.
Strip semiconductors out and the picture inverts. The overall August 1-25 trade surplus was $23.08 billion. Chip exports of $35.48 billion less chip imports of $9.30 billion gives a semiconductor net export of $26.17 billion. Everything else combined ran a $3.09 billion deficit. Last month it took the whole ICT sector to exceed the total surplus; in August, chips alone do it.
Equipment imports round out the picture: $2.57 billion in August, up 117.3%, the largest increase among non-energy imports. Rising prices and rising capex in the same month is what a supply response looks like, and equipment imports are a leading indicator for next year's volume.
What I actually watch
| When | What | Why |
|---|---|---|
| ~Sep 11 | Korea Customs, Sep 1-10 preliminary | Does the late-August $2.58bn/day pace carry into September |
| ~Sep 14 | ICT trade report: memory and SSD detail, ICT balance | DRAM and NAND value per kg, logic breakdown |
| ~Sep 15 | Korea Customs final August data | Size of revision to $46.65bn and the 21-31 back-calculation |
| Late Sep | TrendForce Q3 contract close; Micron FQ4 results | Whether the +18-23% PC DRAM call lands; Q4 negotiation tone |
| Oct 1 | September trade report | Chuseok holiday (Sep 24-26) cuts working days; read per-day |
Value chain read-through
| Segment | What August says | Next check |
|---|---|---|
| DRAM makers (Samsung, SK hynix, Micron) | Shipments carried value in a month of slowing contract prices | Do monthly contract gains stay single-digit; direction of implied volume |
| NAND and enterprise SSD | Record SSD exports; US computer exports up 10x | Gap between eSSD contract prices and SSD export value |
| Chip equipment | Equipment imports +117.3%; precision machinery imports surging | Persistence of the import trend as a 2027 volume lead |
| Logic and foundry | +24.4%, negligible next to memory | Logic detail in the ICT report |
| Macro and FX | Average August won at 1,475.1 per dollar; won-denominated exports +79.0% | Whether the widening China surplus becomes a trade-policy issue |
Risks to this view
• Preliminary data. Every monthly figure here is a customs preliminary through August 31 and can be revised until the annual statistics are finalized in February 2027. July chips were already nudged from $41.02 billion at first release to $41.01 billion in this report.
• Price peak signals. All three contract benchmarks slowed to single-digit monthly gains. TrendForce raised its Q3 PC DRAM contract forecast to +18-23%, but expects NAND MLC gains to keep narrowing as buyers push back on cost. If volume stops offsetting the price slowdown, export value turns quickly.
• Concentration. China plus Hong Kong is roughly half of chip exports, and a bilateral surplus with China that did not exist a year ago is the kind of number that shows up in trade negotiations.
• Calendar. September loses working days to the Chuseok holiday. A month-on-month decline in headline value is likely and should be read on a per-day basis.
• Method limits. The implied volume index and the late-month daily rates are back-calculations from published aggregates, not customs tonnage or bit-shipment data.
The short version: August set a new record in dollars, and the character of the gain changed. A month in which contract prices grew low single digits and export value grew double digits is a month in which shipments moved. The question for September is whether that volume keeps offsetting the fading price tailwind.
