What's in the G Fund
The G Fund invests in short-term U.S. Treasury securities issued only to the TSP. Its interest rate is set each month from the average yield of longer-term Treasury securities, and the U.S. government guarantees payment of principal and interest.
Risk: Designed not to lose value. The trade-off is that its long-term growth may not keep up with inflation.
