February 2026 marked a clear turning point for Thrift Savings Plan (TSP) participants, with international stocks delivering standout gains while U.S. equities faced headwinds. Economic crosscurrents sparked a rotation toward overseas markets and away from U.S. mega-caps. This dynamic highlighted the TSP’s built-in diversification benefits, particularly through exposure to developed international equities.
Performance Summary for the Core Funds
The table below shows February returns alongside year-to-date (YTD) and trailing 12-month figures, based on TSP-reported data and aligned market benchmarks:
| Fund | Description | February Return | YTD Return | 12-Month Return |
|---|---|---|---|---|
| G Fund | Government securities (low-risk) | +0.33% | +0.70% | +4.39% |
| F Fund | U.S. fixed income (bonds) | +1.63% | +1.84% | +6.28% |
| C Fund | S&P 500 large-cap stocks | -0.76% | +0.68% | +16.96% |
| S Fund | U.S. small/mid-cap stocks | +1.08% | +3.52% | +16.58% |
| I Fund | International developed markets | +6.05% | +12.34% | +42.22% |
The I Fund’s momentum carried forward from its +5.94% January advance, driving exceptional YTD gains.
Factors Shaping February’s Results
- G Fund (+0.33%): Delivered predictable, low-volatility returns via special-issue Treasuries yielding roughly 4.25% annualized. It served as a steady buffer against broader market fluctuations.
- F Fund (+1.63%): Captured gains from a bond-market rally, as Treasury yields declined (e.g., 10-year near 3.97%). Safe-haven flows intensified amid Middle East developments and mixed inflation signals like an elevated PPI.
- C Fund (-0.76%): Reflected S&P 500 weakness, pressured by AI stock corrections (e.g., sharp drops in names like Nvidia), policy-related jitters, and stretched valuations. Defensive sectors provided some offset, but overall momentum stalled.
- S Fund (+1.08%): Outpaced large caps amid a shift to value and cyclical areas (energy, materials). Easing short-term rates supported smaller firms’ borrowing and growth prospects.
- I Fund (+6.05%): Benefited from a depreciating U.S. dollar (boosting currency-adjusted returns), more attractive foreign valuations, and inflows into Europe and Japan. Tailwinds included governance improvements in Japan, Asian AI momentum, and spillover from emerging-market earnings strength.
Implications for TSP Investors
The I Fund’s remarkable 12-month performance demonstrates how TSP diversification can enhance long-term outcomes.
