In my humble opinion, G Fund should be the pillar of your near-term Fixed-income Bucket. It's a great tool to use in the early years of retirement to avoid Sequence of Returns Risk. G Fund has unique advantages not found in ANY other fixed-income product:
.1. Guaranteed yields equivalent to 5-year Treasuries
.2. Daily liquidity of a Money Market Fund
.3. Solid track record of outpacing inflation
.4. G Fund has NEVER had a bad day (not sensitive to interest rate swings). The only down side of using TSP's G Fund is that TSP does not automatically take your withdrawals out of your G Fund balance (Like most brokerages draw your Cash/MMF balance first). TSP makes you take withdrawals 'pro rata', proportionally from all of your TSP portfolio- So you'll have to re-balance your TSP allocation every time you withdraw if you want to take money exclusively from your G Fund balance.
