Market Fear and Your TSP: Why Running to the G Fund Costs You

When the market drops, everything tells you to do something. The headlines are red. Your TSP balance is smaller than it was last month. Somebody at work swears they're "going to cash until this blows over." And the G Fund is sitting right there, the one fund that can't lose money.

Moving there feels like the responsible move. For most people, it's the most expensive one.

I got serious about investing in 2020, right as COVID was tanking the market and every headline said it was the worst time to start. Buying and holding through that fear taught me more than any book did: the scary days and the recovery days tend to show up together.

What the "fear" gauge actually measures

You've probably seen it: CNN's Fear & Greed Index, a dial from 0 to 100. Under 25 is "extreme fear," over 75 is "extreme greed."

It's built from seven market signals, weighted equally:

• how the S&P 500 is trading compared to its average over the past 125 days
• how many stocks are hitting 52-week highs versus 52-week lows
• how much trading is happening in stocks going up versus stocks going down
• how many investors are buying options that bet on a drop versus a rise
• how much extra return investors are demanding to own riskier bonds
• market volatility, measured by the VIX
• whether money is flowing out of stocks and into safer government bonds

Every one of those measures how investors feel right now. None of them predicts what happens next. It's a mood ring for the market, not a forecast. Extreme fear tells you people are scared. It doesn't tell you they're right.

What TSP investors actually did in the last big scare

This isn't theory. In March 2025, stocks were falling fast. According to the TSP's own board meeting minutes, about $16 billion moved into the G Fund that month on a net basis, while more than $14 billion left the C Fund and more than $7 billion left the S Fund. About 3.77% of accounts moved money, almost double the normal rate.

Then in early April, stocks fell harder. From its high, the S&P 500 dropped about 19%.

By June 27, 2025, it closed at a new record high.

To be fair, anyone who moved in March did dodge part of April's drop. But anyone who stayed in the G Fund missed the rebound to a record high, and people who simply held on ended up above where they were when the panic started.

Why the move costs more than it saves

You sell after the damage is done. By the time the fear gauge is flashing red, prices have already fallen. Moving to the G Fund then doesn't avoid the loss. It locks it in.

The best days hide right next to the worst ones. J.P. Morgan looked at $10,000 invested in the S&P 500 from 2006 through 2025:

• Stay fully invested: $80,619
• Miss just the 10 best days: $35,866
• Miss the 20 best days: $21,177

Over those 20 years, six of the 10 best days came within two weeks of the 10 worst. In 2020, the second-worst day of the year, March 12, was followed immediately by the second-best day. If you bail on a bad day, you're very likely gone for the good day that follows.

The G Fund protects your principal, not your future. It can't lose money, and that's real. But the TSP itself warns that it may not grow enough to keep up with inflation. Its job is stability, not growth.

The TSP rule most people don't know about

The TSP gives you two unrestricted interfund transfers per calendar month. After you've used them, you can still move money, but only into the G Fund.

Think about what that means in a panic. Getting out is always open. Getting back into stocks is rationed. If you jump to the G Fund, change your mind, jump back, and get nervous again, you can find yourself stuck in G until next month while the market moves without you.

When moving toward the G Fund actually makes sense

The G Fund isn't the villain. It has a real job:

• You need the money soon. If you're a few years from retirement or separation and plan to draw on your TSP, shifting part of it toward the G and F Funds lowers the chance a crash hits right when you need to withdraw.
• You're rebalancing on purpose. Moving money back to your target mix once a year is a plan, not a panic.
• The L Funds do it for you. A Lifecycle fund automatically shifts toward safer funds as its target date gets closer.

The difference is timing and reason. A move decided months ahead, based on when you'll need the money, is a strategy. A move made because the headlines are scary is a reaction.

What to do instead when the market drops

1. Decide your rule now, while you're calm. Write it down: "If the market drops 20%, I don't touch my allocation." A decision made ahead of time beats one made in the moment.

2. Keep contributing. Every paycheck buys shares. When prices are down, the same dollars buy more of them. And whatever you do, keep contributing at least 5% of base pay if you're under BRS, so you never give up the full match.

3. Stop checking your balance every day. The more often you look, the more often you'll see red, and the more tempted you'll be to act.

4. Keep an emergency fund outside the TSP. Panic-selling often starts with needing cash. If three to six months of expenses sit in savings, a market drop is just a number on a screen.

5. Check your allocation once a year, not once a crisis. Pick a date (your birthday, the first week of January) and make changes then.

The bottom line

The Fear & Greed Index measures emotion, not the future. In the last big scare, billions of TSP dollars ran to the G Fund right before stocks recovered to record highs. The best days tend to come right after the worst ones, and the TSP's own rules make it easier to get out than to get back in.

Set your plan when you're calm, keep contributing through the red, and let time do the heavy lifting.
