AI chip demand lifts Korea 2026 growth forecast to 3.3 percent
The Bank of Korea raised its 2026 GDP growth forecast by 0.7 percentage points to 3.3 percent, driven by a broadening semiconductor boom. In its August outlook, the central bank held its consumer inflation projection at 2.7 percent while projecting a record current account surplus.
Export surge drives growth upgrade
The 0.7 percentage point upgrade to 2026 growth reflects a stronger-than-expected AI semiconductor rally, which contributed 0.35 percentage points to the revision, alongside upward adjustments to historical data and three mega projects.
Goods export growth is projected at 9.7 percent this year, up from 4.9 percent in May, while facilities investment is seen expanding 6.8 percent.
For 2027, GDP growth is forecast to reach 2.9 percent as the chip cycle broadens into the wider domestic economy.
Underpinned by surging memory export prices and global AI infrastructure spending, the current account surplus is projected to hit a record $450.0 billion in 2026, up from $123.1 billion in 2025.
Mideast energy and tariff crosscurrents
The baseline assumes Brent crude averages $86 per barrel in 2026 before easing to $74 in 2027 as Strait of Hormuz transit partially recovers.
However, geopolitical friction and trade barriers pose tangible downside risks.
Current trade assumptions incorporate US forced-labor tariffs of 12.5 percent, alongside expected 15 percent semiconductor tariffs starting in early 2027.
Scenario modeling indicates that a retrenchment in Big Tech AI infrastructure spending would lower 2027 GDP growth by 0.4 percentage points.
A monoculture built on fragile assumptions
The upgrade underscores Korea's heavy reliance on a single AI hardware supercycle.
By banking on record trade surpluses while downplaying Middle East oil shocks and US tariffs, the outlook rests on fragile assumptions.
A sudden slowdown in global tech capex will quickly puncture this momentum.
