South Korea's National Pension Service reported a 27.2% return in the first half of 2026, its best first-half performance since at least 2022, driven by gains in domestic equities that surged 107.37% over the period.
The $1.35 trillion fund's half-year result marks a sharp outperformance relative to its overseas holdings, which returned 17.81% in the same span. Domestic equity allocations returned 107.37% while international holdings returned 17.81%, a 90-percentage-point gap that is more than six times the historical average for such periods.
The National Pension Service is South Korea's primary public pension, covering private-sector workers and self-employed contributors. As of June 30, 2026, the fund held $1.35 trillion in total assets, making it the fourth-largest pension fund globally by assets under management. The fund publishes half-year and full-year returns to show performance across its domestic and international portfolios.
Domestic equity allocations typically make up a significant portion of the NPS portfolio. The 107.37% return on Korean holdings in H1 2026 far exceeded the overseas return. The fund's typical half-year returns range between 5% and 15% when markets move at their long-term averages.
The fund's 27.2% first-half return compares to a 23.1% return in the first half of 2025, according to the fund's historical disclosures. The improvement of 4.1 percentage points year-over-year points to an acceleration in Korean equity valuations or trading volumes that benefited large passive positions held by the pension in 2026 versus 2025.
The National Pension Service manages contributions from millions of Korean workers and retirees and must maintain sufficient liquidity to meet pension obligations. Strong H1 performance can allow the fund to reduce the rate at which it draws from reserves or to increase allocation to higher-risk positions later in the year, depending on liability forecasts and board decisions.
If the domestic rally continues into H2, full-year 2026 returns could exceed the fund's long-term target of 5.5% real returns, assuming stable market conditions.
