Overlap with the other TSP funds

| TSP F Fund | 2.4% | 2.0 |

Frequently asked
What does the TSP I Fund actually hold?
The I Fund tracks a broad index of non-US developed and emerging markets. The Thrift Savings Plan does not publish a holdings list and does not file SEC form N-PORT, so this page shows the 8,453 positions of VXUS, which tracks the same index, as of 2026-06-30. The largest position is 2330 at 4.3%, and the top ten are 16.3% of the fund.
Is this the TSP's real holdings data?
No, and that distinction matters. It is a labelled proxy: a different fund tracking the same index, not the I Fund itself. VXUS holds a broad ex-US basket and is the closest covered equivalent to the I Fund's mandate. Index funds tracking the same benchmark hold nearly identical portfolios, so the picture is close — but the weights are VXUS's, not the TSP's, and the TSP has never published its own.
How much do the TSP funds overlap each other?
The I Fund overlaps the S Fund 4.5% by weight — S Fund 4.5%, F Fund 2.4%, C Fund 1.0%. Overlap is the sum of the smaller weight in each fund over every holding both own, computed from the proxy holdings described above.
Why isn't the G Fund shown?
The G Fund is deliberately absent. It holds non-marketable US Treasury securities issued only to the TSP, which are not traded anywhere and have no market equivalent. Showing it through a bond fund would misrepresent an instrument whose defining feature is that its principal cannot fall.
Most federal employees hold more than the TSP
A TSP account is rarely the whole picture — there is often an IRA, a spouse's 401(k), or a brokerage account alongside it. Paste them all together to see the real overlap between your I Fund and everything else you own, and your own Effective Funds number. Free, no account, nothing stored.
