If you've logged into your TSP account in the last week, you've probably had the same reaction as a lot of other service members and retirees: a small, quiet "ouch." The C Fund dropped nearly 5% in March. The S Fund fell 4.58%. Then on April 2, a new round of tariff announcements hit the market, and the S&P 500 slid again on April 3. The G Fund, boring and steady as always, was the only TSP fund in the green for March at 0.34%.
Cue the chatroom advice, the forum posts, and the coworker who swears he moved everything to the G Fund "right before the crash." Before you do anything rash with your retirement money, take a breath. Market drops are uncomfortable, but they are not emergencies, and for most military members the worst mistakes get made in exactly this kind of environment.
This guide walks through what's actually happening with the TSP in early 2026, why tariffs are moving the market, what the data says about how service members should respond, and a clear playbook for handling the volatility without doing permanent damage to your account.
The one sentence version: Don't panic-move to the G Fund, don't reduce your contributions, and don't try to time the market. If you're under BRS, keep contributing at least 5% to capture the full match.

What's Actually Happening to the Market
In March 2026, the S&P 500 had its worst month in nearly a year. Every TSP stock fund except the G Fund finished the month in the red. Then, on April 2, the administration announced a sweeping new round of reciprocal tariffs, pushing the average effective U.S. tariff rate from 2.3% at the end of 2024 to roughly 15.8%, the highest level in decades. The S&P 500 dropped sharply on April 3 in response.
The market is reacting to three things at once:
- Tariff-driven inflation fears. Higher import costs flow through to consumer prices, which complicates the Federal Reserve's path on interest rates.
- Earnings uncertainty. Companies that rely on global supply chains (which is most of the S&P 500) face margin pressure.
- High starting valuations. The Shiller P/E ratio hit its second-highest level ever in late December 2025. When stocks are priced for perfection, any shock hurts more.
Historical perspective: Since 1928, the S&P 500 has averaged about one 10% correction per year. Market drops are not unusual. They're the price of admission for long-term stock returns. The unusual thing is going years without a correction, which we mostly did from 2023 through early 2026.
2026 TSP Fund Performance So Far
Here's how each TSP fund has performed through the end of March 2026, before the April tariff announcements took additional bites out of stock prices:
| Fund | What It Holds | March 2026 | 2026 YTD (through March) |
|---|---|---|---|
| G Fund | Special Treasury securities (cash-like) | +0.34% | +1.04% |
| F Fund | U.S. investment-grade bonds | -1.77% | -1.15% |
| C Fund | S&P 500 (large U.S. stocks) | -4.98% | -4.34% |
| S Fund | Small & mid-cap U.S. stocks | -4.58% | -1.22% |
| I Fund | International developed-market stocks | -3.90% | +1.84% |
Source: Thrift Savings Plan (tsp.gov), March 2026 monthly returns.
A few things worth noticing in that table. First, the I Fund is actually the only stock fund still positive for the year, a helpful reminder that international diversification does earn its keep sometimes. Second, the F Fund didn't protect you the way bonds "used to." In a typical correction you'd expect bonds to rally while stocks fall, but with inflation concerns front and center, both have struggled. Third, the G Fund's 1.04% YTD gain looks attractive right now, but that's roughly a 4% annualized pace. Over 20 years, that won't keep up with inflation plus the COLA growth in your retirement pay, let alone beat it.
Why This Hits Military Members Differently
Financial advice for civilians treats market volatility as a pure investing question. For military members, it's also tangled up with transition, deployment, allowance fluctuations, and the unique structure of military retirement. A few things make your situation different.
1. You have a built-in "pension" most civilians don't
If you serve 20+ years, you get a defined-benefit military retirement paycheck for life, with annual COLA adjustments. That is, in investing terms, a giant inflation-protected bond. It means you can afford to be more aggressive in your TSP than the average civilian investor, because you already have a guaranteed income stream. A lot of retirees spend years under-allocating to stocks and missing out on growth because they forget they already own the equivalent of a massive bond portfolio.
2. Contributions come with a 5% match (under BRS)
If you're under the Blended Retirement System, the DoD contributes 1% automatically and matches your first 5% of contributions (dollar-for-dollar on the first 3% and fifty cents on the next 2%). Cutting contributions when the market drops means leaving that match on the table. That is not risk management. It's voluntarily taking a 100% loss on free money.
3. Deployments and CZTE create tax-planning opportunities
Combat zone pay is tax-free, and TSP contributions from CZTE pay go into your account with a special tax status that most civilians never get. Market drops during a deployment are a rare window to buy discounted shares with tax-advantaged dollars. (We covered this in detail in our CZTE Roth conversion guide.)
4. Your "retirement age" is way earlier than civilians'
Military retirees often start pulling their pension in their early 40s. That means a 40-year-old E-7 might have a 50-year investment horizon for their TSP money. Panic-selling stocks because of a month of tariff headlines is the wrong move when your money has 50 years to compound.
A better way to think about your TSP: Stop thinking of it as "the money I could lose." Start thinking of it as the growth engine that complements your guaranteed pension. You don't need your TSP to also be guaranteed, because your pension already is.
Sequence of Returns Risk: The Real Danger for Retirees
Here's where things get more nuanced. While young service members should basically ignore short-term market drops, recently retired veterans face a real risk called "sequence of returns risk." This is one of the most important concepts in retirement planning, and a lot of people don't understand it until it bites them.
The idea is simple. If the market crashes before you retire, you have years to recover. If the market crashes after you retire and you're taking withdrawals, you're selling shares at low prices, and those shares are gone permanently. Even if the market rebounds, your account has fewer shares to rebound with.
Here's a simplified example to make the math concrete:
| Scenario | Year 1 Return | Year 2 Return | Year 3 Return | Avg Return | Still Have Money? |
|---|---|---|---|---|---|
| Bad sequence | -20% | -10% | +25% | -1.67% | Much less |
| Good sequence | +25% | -10% | -20% | -1.67% | Much more |
Same three returns in different order. Same average. Completely different outcomes for a retiree taking monthly withdrawals. The bad sequence can turn a comfortable retirement into a stressful one. Not because the average was bad, but because the timing was.
If you retired from the military in the last 2 or 3 years and your TSP is your main supplemental income source, this is your risk. The fix isn't to panic-sell. It's to have a plan built before the drop, with a cash or G Fund "bucket" of 1 to 2 years of expenses so you don't have to sell stock funds at the bottom to pay bills.
The G Fund Trap: Why "Safe" Isn't Always Safe
The G Fund is unique. It's only available to TSP participants, it never loses money, and in 2026 it's paying around 4% annualized. After a month like March 2026, it looks like a superhero. And every time the market drops, a predictable wave of participants moves everything to the G Fund.
The problem is that over the long run, the G Fund almost always loses to stocks. When inflation is running hot (as it is with tariff-driven price increases), the G Fund's real return after inflation can be very close to zero, or even negative.
Here's what the long-run data actually says:
- Since 1988, the C Fund has averaged roughly 11% per year. The G Fund has averaged roughly 5%. Over a 30-year career, that difference is measured in hundreds of thousands of dollars per $100K invested.
- After every major correction in the last 30 years (1990, 2000 to 2002, 2008 to 2009, 2020, 2022), the market has recovered and made new highs. Participants who panic-sold locked in losses, missed the recovery, and often didn't get back in until prices were already high again.
- The G Fund's "no losses" guarantee is nominal only. If inflation runs at 4% and the G Fund pays 4%, your real return is zero. You haven't lost dollars, but you've lost purchasing power, and that matters more in retirement than the number on your statement.
The G Fund has a job, but it's not "refuge during corrections." Its job is to be a stability anchor for people who are already near or in retirement, so they can pay bills without selling stocks at bad prices. If you're 25 and you move to 100% G Fund because of one bad month, you're solving a problem you don't have by creating a much bigger one.
Lifecycle Funds: The Easy Mode Most People Should Use
If you're reading this and thinking "I don't want to make any of these decisions myself," good. For most people, that's the smartest possible conclusion. The TSP has a built-in answer: Lifecycle Funds (L Funds).
L Funds are target-date retirement funds. You pick the one closest to the year you'll retire, and the fund automatically allocates between G, F, C, S, and I for you. More aggressive when you're young, gradually more conservative as retirement approaches. When stocks drop, the fund automatically rebalances, effectively buying low on your behalf. No logins, no guesswork, no emotion.
| L Fund | Target Retirement Year | Who It's For |
|---|---|---|
| L Income | Already retired | Retirees currently drawing down their TSP |
| L 2030 | 2028 to 2032 | Service members or retirees near retirement now |
| L 2035 | 2033 to 2037 | Mid-career members planning a transition soon |
| L 2040 | 2038 to 2042 | Mid-career members, about 15 years out |
| L 2045 | 2043 to 2047 | Members about 20 years from retirement |
| L 2050 | 2048 to 2052 | Early-career members |
| L 2055 / 2060 / 2065 / 2070 | 2053 and later | Brand new to military service |
The L Funds are not magic. They still hold the same C, S, I, F, and G funds that dropped in March. But they take the emotional decision-making out of your hands, and emotion is where most retirement money goes to die.
If you do nothing else after reading this article: log into TSP, pick the L Fund matching your approximate retirement year, and put 100% of your balance and future contributions into it. That single decision puts you ahead of the majority of military investors who try to time the market and fail.
The Combat Zone Tax Exclusion Opportunity
Here's an angle most civilians will never experience: if you're deployed to a combat zone and earning Combat Zone Tax Exclusion (CZTE) pay, a market drop might actually be one of the best things that could happen to your long-term wealth. Here's why.
While deployed to a CZTE zone, your military pay is federally tax-free. TSP contributions made from that tax-free pay go in as tax-exempt traditional contributions, which means those dollars never get taxed, even when you withdraw them in retirement. That's a benefit civilians literally cannot replicate.
When you combine tax-free dollars with discounted share prices during a market drop, you're essentially getting a double discount. The tariff-driven drop of April 2026 is painful in the moment, but for a deployed service member contributing to the TSP, it's the investing equivalent of buying a car during a holiday sale, with tax-free money.
The 2026 annual additions limit is $72,000, which includes your elective deferrals, service match, and any CZTE contributions. Deployed troops can contribute aggressively up to that $72K ceiling, which is roughly three times the normal elective deferral limit. If you're deployed and the market is dropping, that's a rare window to push contributions hard.
CZTE pro tip: Talk to your finance office about maxing out traditional TSP contributions from CZTE pay. Tax-exempt traditional contributions grow tax-deferred, and when you withdraw them in retirement, the basis comes out tax-free. Just be aware of Roth vs traditional rules. There are important nuances. See our CZTE guide for the full playbook.
7 Smart Moves in a Volatile Market
Enough theory. Here is a straightforward checklist for military investors dealing with the April 2026 tariff-driven volatility.
1. Confirm you're capturing the full BRS match
If you're under the Blended Retirement System, log into MyPay and verify you're contributing at least 5% of base pay. That's the threshold to capture the full 5% match. If you're below 5%, raise it today. The match is the highest-return move available in your entire military career, and it doesn't care what the market is doing.
2. Pick your lane: L Fund or intentional allocation
Either go with a single Lifecycle Fund matching your retirement year, or build an intentional C/S/I/F/G mix you can defend with logic (not feelings). What you want to avoid is a mishmash allocation you set up three years ago and never revisited.
3. Rebalance (if you manage your own mix)
If you self-manage, use this downturn as a rebalancing opportunity. If your original target was 70% stocks and 30% fixed income, the stock drop probably pushed you to something like 65/35. Rebalancing back to 70/30 forces you to buy low, which is exactly what everyone says to do but nobody actually does when it hurts.
4. Do NOT reduce contributions
This is the opposite of what panicked investors do, and it's the most important move. Every payday you contribute during a downturn, you're buying more shares for the same dollar amount. You are literally loading up at a discount. Cutting contributions during a drop locks in the worst of both worlds: losses on what you already own, plus missed opportunities on what you would have bought cheap.
5. Build a 1 to 2 year cash bucket (if you're near or in retirement)
This is where the G Fund earns its keep. If you're within 5 years of retirement, or already retired, hold 1 to 2 years of living expenses in G Fund (or cash outside the TSP) so you're never forced to sell C/S/I at the bottom to pay the mortgage. This isn't market timing. It's liquidity planning.
6. Check your beneficiaries and overall plan
When you log in to look at the damage, take two extra minutes. Is your beneficiary still correct? Is your allocation still aligned with your timeline? Are you on track with our retirement calculator? Downturns are a great prompt to zoom out and check the plan. Just don't confuse "checking the plan" with "changing the plan."
7. Tune out the noise
No one on CNBC, on X, or in your barracks break room knows what the market is going to do next. The people telling you "you have to get out now" don't have a crystal ball. They have confidence, which is not the same thing. Close the app, go do PT, come back in six months.
BRS Matching: Why Market Drops Are Your Friend
Here are the actual numbers on why BRS matching changes everything during a downturn. Imagine an O-3 with two years of service earning about $5,700 in monthly base pay. Contributing 5% of base pay means $285 per month goes into the TSP from the service member, plus another $285 in matching plus the automatic 1%, which is roughly $342 in "free" money every month.
| Scenario | Monthly Contribution | Service Match + 1% | Total Monthly TSP Deposit |
|---|---|---|---|
| Panicked cut to 0% | $0 | $57 (1% auto only) | $57 |
| Reduced to 3% | $171 | $228 (partial match) | $399 |
| Full 5% (min to max match) | $285 | $342 (full match) | $627 |
The 5% contributor is putting $627 per month into their TSP during the downturn, buying C, S, and I Fund shares at prices that are around 5% cheaper than a month ago. The panicked quitter is putting in $57 and leaving roughly $285 per month of employer match on the floor. Over a 20-year career, the difference compounds into six figures. That's the actual cost of panic.
The match is untouchable. No matter what the market does, the 5% BRS match is a 100% instant return on your 5% contribution. There is no stock, bond, or scheme on earth that reliably matches that. The first rule of military TSP strategy is: never, ever leave the match on the table.
Common Panic Mistakes to Avoid
We've hinted at these throughout, but they deserve their own list. If you see yourself about to do any of the following, stop and re-read this section first.
Mistake #1: Moving 100% to the G Fund
This is the classic. It feels like "taking control" but it's really just locking in losses and missing the recovery. Historical data is consistent: investors who stayed invested through every major correction since 1990 came out ahead of those who moved to cash and "waited it out."
Mistake #2: Taking a TSP loan to "pay off debt"
When stocks drop, a TSP loan sells your shares at the low to give you cash. Even if you pay the loan back, you've permanently missed the rebound on those shares. And if you separate from the military before the loan is repaid, it becomes a taxable distribution, often with a 10% early-withdrawal penalty on top. Avoid TSP loans in a downturn.
Mistake #3: Halting contributions to "wait until things stabilize"
"Things" never announce when they're stable. By the time the market feels safe, it has already rallied 15% to 25% and you're buying in at higher prices than you panic-sold at. This is the literal definition of buying high and selling low.
Mistake #4: Moving into a single fund based on past performance
"The I Fund was the only thing up YTD, let me go 100% I Fund." Don't. Chasing the last winner is the oldest mistake in investing. Diversification exists because you don't know which fund will lead next.
Mistake #5: Checking your balance every day
There is zero upside to watching your balance tick down every morning over coffee. The people who look less are the people who stay calmer and make fewer expensive moves. Set your plan, automate contributions, and check your statement quarterly at most.
The pattern to watch for: If you find yourself opening the TSP app "just to see," feeling physically anxious about red numbers, and reading a dozen Reddit threads on fund rotation, you're in the danger zone. That's the moment where expensive mistakes happen. Close the app, take a walk, talk to a qualified financial professional, and don't make changes on a bad day.
The Bottom Line
Tariffs are real. The market drop is real. The concerns about inflation and earnings are real. None of that means you should abandon the strategy that built your TSP balance in the first place.
If you're a young service member, the April 2026 drop is a gift. You're buying cheaper shares with matched dollars that will compound for 30 or 40 years. If you're mid-career, it's an opportunity to confirm your allocation makes sense and rebalance if it doesn't. If you're near or in retirement, it's a reminder to have a cash bucket so you don't have to sell low, and a good time to look carefully at your overall income plan.
The worst move you can make right now is a big one. Panic allocation changes, halted contributions, TSP loans: these are the decisions that turn a normal correction into a permanent setback. The best move is usually the boring one. Stay the course, capture the match, let the L Fund or your chosen allocation do its job, and revisit when prices are higher, not lower.

Frequently Asked Questions
Should I move my TSP to the G Fund because of tariffs?
For most military members, especially those more than 10 years from retirement, no. Moving everything to the G Fund during a market downturn is one of the most common and most damaging mistakes TSP participants make. You lock in losses, miss the recovery, and trade long-term growth for short-term comfort. The G Fund has a legitimate role as a stability anchor for those already in or near retirement, but as a panic reaction it's almost always the wrong call.
How much did TSP funds lose from the April 2026 tariff announcements?
In March 2026, ahead of the April 2 tariff announcements, the C Fund lost 4.98%, the S Fund lost 4.58%, and the F Fund lost 1.77%. The G Fund was the only TSP fund with a positive monthly return, gaining 0.34%. After the April 2 and 3 tariff announcements, the S&P 500 fell sharply, meaning April results will show additional losses in the C, S, and I Funds. Exact April numbers won't be finalized until early May.
Should I still contribute to my TSP during a market drop?
Yes, and you should not reduce your contributions. Under BRS, the 5% match is free money and it doesn't care what the market is doing. Market drops also mean your contributions buy more shares for the same dollar amount. The shares you buy during the April 2026 downturn may be some of the best-performing money in your account a decade from now.
Are Lifecycle (L) Funds a good choice in volatile markets?
Yes. L Funds automatically rebalance between G, F, C, S, and I based on your target retirement year. During volatile markets, they sell what's gone up and buy what's gone down on your behalf, without you having to make any decisions. For the majority of military investors, a single L Fund matched to your retirement year is the simplest and most effective approach.
What's the 2026 TSP contribution limit?
The 2026 elective deferral limit is $24,500, up from $23,500 in 2025. The catch-up contribution for participants age 50+ is $8,000, and participants age 60 to 63 can contribute a "super catch-up" of $11,250. The total annual additions limit (which includes the service match and CZTE contributions) is $72,000.
What about the I Fund? It's positive YTD.
The I Fund benefited from strong international developed-market performance earlier in 2026 before falling in March along with the rest. Being positive YTD doesn't mean you should load up on the I Fund now. That's chasing past performance. The better lesson is that diversification across U.S. and international stocks smooths returns, which is exactly how the Lifecycle Funds are already built.
