South Korea’s economy strengthened in 2026, supported by the global AI and semiconductor cycle, stronger exports, fiscal support and a gradual recovery in domestic demand. Growth is expected to moderate in 2027 as base effects fade and export momentum normalises, but it should remain close to potential. Inflation has risen again because of higher oil prices, airfares and import costs, prompting the Bank of Korea to shift toward a more cautious policy stance. The external position remains strong, supported by semiconductor exports and services income, while fiscal pressures are increasing due to ageing, defence, industrial policy and social spending needs.

Growth improves on semiconductors and AI demand
South Korea’s real GDP growth slowed to around 1.0% in 2025, reflecting weak domestic demand, cautious private consumption and delayed investment. However, exports improved strongly in late 2025 and early 2026, led by semiconductors, AI-related memory chips, servers and other high-value technology products.
Growth is projected to rise to around 2.6% in 2026 before moderating to 2.1% in 2027. The recovery is supported by semiconductor exports, fiscal stimulus, stronger real wages and gradual improvement in private consumption. However, construction remains weak, household debt is high, and the export cycle remains vulnerable to global technology demand.
Semiconductor exports remain the main engine
The technology cycle is the main driver of South Korea’s near-term outlook. Global AI investment has boosted demand for high-bandwidth memory, advanced chips and related equipment, benefiting major Korean exporters and supporting corporate profits, investment and equity-market sentiment.
However, concentration in semiconductors creates risks. A slowdown in AI-related capital expenditure, stronger competition, export controls, US-China tensions or weaker Chinese demand would quickly affect exports and business confidence. Diversifying services exports and strengthening domestic demand will be important for reducing reliance on the electronics cycle.
Inflation rises after the oil-price shock
Inflation rose sharply in 2026, with headline inflation reaching its highest level in more than two years in May, mainly because of higher petroleum prices, international airfares and import costs. The Bank of Korea raised its 2026 inflation forecast and signalled a more hawkish stance as inflation moved above the 2% target.
Inflation is projected to average around 2.7% in 2026 before easing to 2.3% in 2027. Fuel-price caps and tax measures may soften the immediate impact of energy prices, but they can also make disinflation more persistent. Risks remain linked to oil prices, the won exchange rate, services inflation and wage pressures.
Fiscal pressures are increasing
The fiscal deficit is expected to widen in 2026 as the government uses fiscal support to strengthen the recovery and cushion households from higher energy costs. Public debt remains moderate compared with many advanced economies, but it is rising steadily as ageing-related spending, healthcare, pensions, defence and industrial-policy costs increase.
Gross public debt is projected to rise from about 54.4% of GDP in 2025 to around 58% by 2027. Korea still has significant fiscal space, but the medium-term trajectory points to growing pressure unless revenue mobilisation and spending efficiency improve.
External position remains strong
South Korea’s current account surplus is expected to remain large, supported by semiconductor exports, technology-related goods, services income and lower non-energy import growth. The surplus is projected to stay around 5% of GDP in 2026–2027, providing a key buffer against external shocks.
The main external risks are weaker global electronics demand, higher energy import costs, US-China trade tensions, financial-market volatility and exchange-rate pressure. Korea’s energy import dependence also makes it sensitive to Middle East disruptions and global oil-price shocks.
Overall outlook
South Korea’s outlook has improved materially in 2026, driven by the AI semiconductor cycle and stronger export performance. Growth should remain solid in 2026 before moderating in 2027, while inflation is expected to ease but remain above target for longer than previously expected. The main medium-term challenges are high household debt, ageing, weak productivity in services, construction-sector weakness and heavy reliance on technology exports. Sustained progress will depend on innovation, labour-market reform, stronger domestic demand and policies that broaden growth beyond semiconductors.
