The G Fund
is often described as the safest of the TSP investment funds. Sometimes it is called the “super safe” G Fund that “never has a bad day.”
As a result, TSP participants keep a higher portion of their TSP balances in the G Fund than any other Fund.
However, there are many types of investment risk. The only guarantees provided by the G Fund are the lack of volatility (fluctuations in value) and the guarantee against loss of principal provided by the Government. None of the other TSP funds offer those guarantees. Click here
for more information on volatility and TSP Fund returns.
However, historically, using the G Fund as a long-term investment exposed investors to a high risk of losing purchasing power. The rate of return for the G (and F) funds was not sufficient to increase purchasing power after subtracting out the negative effects of taxes on withdrawals and inflation.
At the beginning of 1993, retirees Bill, Jack and Mary each have $10,000 in the TSP. They each invest that $10,000 in one fund:
- Bill in G (US Treasury bonds),
- Jack in F (government and corporate bonds) and
- Mary in C (stocks of large US companies).
Each of them withdraws the same dollar amount annually to buy 2000 first class stamps, after paying taxes of 30% on the withdrawals.
Why First Class stamps? First Class stamps are unique in one respect; the value (service provided) is the same year after year. Thirty years ago, one First Class stamp was sufficient to mail a letter anywhere in the US. The same is true today. That makes First Class stamps are a good proxy for inflation.
Result: Even though equal dollar amount are withdrawn from each fund each year, the G Fund is exhausted in 2009 and the F Fund in 2010. But the C Fund still had a positive balance in December 2016. In fact, the C Fund balance was 37% higher.
Yes, fluctuations in value (volatility) are much lower for the G and F Funds. Unfortunately, the low volatility occurs while the G and F Fund values decline to zero.
Few FERS retirees will be able to live on “guaranteed income” (Social Security and Federal annuity) until they die (more information here
). At some point, retirement expenditures will exceed guaranteed income. Retirees then need to start withdrawing from their investments to supplement guaranteed income. Those investment withdrawals need to last as long as the retiree is alive. That will be difficult to achieve if purchasing power of the investments is declining.
Past performance is no guarantee of future performance but tell me why the G Fund is considered so “safe?
