2. The Drivers: Why Such High Returns?
🏆 The 'King-SPI' Rally Effect
In 2025, the KOSPI posted a historic annual gain, driven by Samsung Electronics' HBM earnings recovery, SK Hynix's dominance in AI semiconductors, and the resolution of political uncertainty. The 82.44% domestic equity return shows that the NPS absorbed the full impact of this rally.
🌐 Diversification via Overseas Equities
Overseas equities carried the largest weight (37.8%) and delivered a solid 19.74% return. This reflects the convergence of the US Big Tech AI bull market and broad-based global equity gains.
📈 The Significance of 3 Consecutive Record Years
Posting all-time high returns for three consecutive years — 2023 → 2024 → 2025 — can be evaluated as a structural achievement of the fund's management strategy. In particular, the decision to expand equity allocation to over 55% proved highly effective.
3. Context: How Does This Relate to the NPS Depletion Debate?
The NPS has long faced concerns about fund depletion around 2055 due to low birth rates and an aging population. This record-high return is significant because it could push back that timeline somewhat.
However, while the fund reserves have grown to ₩1,458 trillion, the structural issues of declining contributors and rising beneficiaries remain unresolved.
4. Outlook: Will These Returns Continue in 2026?
Positive Factors
- Expectation of KOSPI holding above the 6,000 level (currently above 6,300 in 2026)
- Continued AI semiconductor cycle → potential dual benefit for domestic and overseas equities
- Weakening dollar trend → improved conversion gains on overseas assets
Negative / Risk Factors
- Base effect: An 82% domestic equity return like 2025 will be difficult to replicate
- Uncertainty in the US Fed's rate path → bond yield volatility
- Global trade disputes (US tariffs) → pressure on earnings of Korea's export-dependent companies
- Deepening K-shaped growth → consumer contraction risk → slowdown in domestic corporate profits
