Bond yields and the G Fund


Q: As the government treasury bond yields go up, does the Thrift Savings Plan’s G Fund share price increase? The opposite would be true of the F Fund, since share prices would be affected in a negative way with rising interests rates.

A: While there are times when the daily return for the G Fund is negative, the monthly and annual change in the G Fund’s share price is always positive.
