A client called me a few weeks ago — I’ll call him Dave, because that’s not his name — and asked me something I hear more and more these days.
“Colby, should I be concerned about the dollar? I keep getting emails about its decline and how it might affect my 401(k). Do I need to do anything?”
Fair question. Dave spent thirty years running operations for a mid-size manufacturer in Orange County. He retired last year, and he’s got a portfolio that’s about to spend the next decade absorbing whatever the market throws at it — in the exact window where a difficult sequence of returns can do lasting damage. The U.S. dollar is one of the bigger levers behind that sequence, and it’s one that many retirement investors don’t think about until after conditions have already shifted.
So yes, Dave. It may be worth paying attention. Here’s why — in plain English, no charts required.

How the Dollar Affects Your Retirement Portfolio
I spend a fair amount of time looking at the U.S. Dollar Index — a measure of the dollar’s strength relative to a basket of major global currencies including the euro, the yen, and the British pound. Since 2021, that index has been on a notable ride: a sharp move higher as the Federal Reserve raised interest rates aggressively, followed by a pullback, then years of choppy sideways movement in what I’ve been calling “no-man’s land” — a range where the dollar hasn’t been able to break decisively in either direction.
That pattern may be starting to shift. The dollar has pushed against the upper end of that range and is testing levels it hasn’t cleanly cleared in some time. The question worth asking — for anyone managing a long-term portfolio — is whether this represents a temporary move or the beginning of a more sustained trend change.
No one can answer that with certainty, and I’d encourage skepticism toward anyone who claims otherwise. But 2026 may prove to be a meaningful year for the dollar’s direction, and that matters more to retirement investors than most headlines suggest.
Why Currency Trends Matter Even If You’re Not a Currency Trader
Here’s the connection that often gets missed. The dollar’s direction has historically rippled through most of the asset classes that retirement investors actually own — and understanding that relationship may help frame how you think about your portfolio.
When the dollar has tended to strengthen:
- Commodity prices — which are priced globally in dollars — have often faced headwinds
- Large U.S. multinational companies with significant overseas revenue may see earnings pressured when foreign income converts back to stronger dollars
- Global financial conditions can tighten, which has historically coincided with more volatile periods for equities
When the dollar has tended to weaken:
- Commodities and precious metals have often received a tailwind
- U.S. exporters and multinationals may report stronger earnings as overseas revenue translates back at more favorable rates
- Some equity markets have experienced strength during weaker-dollar periods, though those environments carry their own risks — including the possibility of rising imported inflation
Neither direction is automatically favorable or unfavorable for a diversified portfolio. What matters is that a shift in the dollar’s trend has historically shown up as a shift in market character — which sectors tend to lead, which lag, and how much volatility investors may experience along the way.
And volatility, timed poorly, is exactly what can turn a manageable retirement into a stressful one.
Sequence of Returns Risk: The Retirement Threat Nobody Talks About Enough
I want to be direct about something: I’m not suggesting you try to trade the dollar, or rotate your entire portfolio based on a currency chart. That’s not the lesson here. Most investors who attempt to time these macro moves don’t get it right, and the transaction costs, tax consequences, and behavioral risks of trying often outweigh any potential benefit.
The real lesson is about something I call the Red Zone — the five years before retirement and the five years after it. During that window, the sequence in which your returns arrive may matter more than your average return over time.
Consider this illustrative example: Two hypothetical investors each retire with $1 million and each earn an average annual return of 5% over ten years. The difference is in the order those returns arrive.
- Investor A experiences strong early returns in years one through three, followed by a difficult stretch later. Because their portfolio is larger when losses occur and smaller distributions are being made in the early years, the damage is more contained.
- Investor B experiences a significant decline in year one — say 20% — while simultaneously drawing income from the portfolio. The combination of a smaller balance and continued withdrawals leaves less capital available to participate in the eventual recovery.
Same average return. Potentially very different outcomes. That’s sequence of returns risk, and it’s why the years immediately surrounding retirement deserve particular attention — especially when macro conditions may be shifting.
Big changes in the dollar’s trend have historically been associated with shifts in market volatility and sector leadership. Not on a predictable schedule, and not every time — but often enough that it’s worth building a plan that doesn’t assume the next five years will look like the last five.
What I’m Actually Watching — And What I Told Dave
I shared three things with Dave, and I think they’re worth passing along.
First: don’t anchor your retirement income plan to any single macro forecast. Not mine, not anyone else’s. Nobody consistently calls dollar tops and bottoms, or predicts the timing of a currency trend reversal. I’ve watched the yen carry trade — where investors borrow cheaply in yen to fund purchases of higher-yielding dollar assets — build and unwind multiple times over my career. Each time, the timing has caught people off guard. Macro transitions are rarely as clean or as early as the forecasts suggest.
Second: understand how much of your portfolio’s current performance depends on the existing trend continuing. If you’re heavily concentrated in assets that have benefited from dollar strength, or positioned specifically for dollar weakness, a real trend change may hit harder than you expect. That’s not necessarily a reason to restructure immediately — but it may be a reason to evaluate whether your current exposure reflects an informed decision or an assumption that’s gone unexamined.
Third: make sure your near-term income needs don’t depend on any single asset class cooperating. This is the practical core of sound retirement sequencing. Keeping cash and short-term reserves available for the next few years of spending may help ensure that a currency-driven volatility spike doesn’t force you to sell longer-term holdings at the wrong time. The goal is to avoid being a forced seller when conditions are unfavorable.
None of these steps require predicting where the dollar goes. They’re about building a plan that may hold up across a range of possible outcomes — including ones that look different from recent experience.
Stress-Testing Your Retirement Plan: What That Actually Looks Like
For clients in or near the Red Zone, I often suggest working through a few basic scenarios:
- What does your income plan look like if your portfolio experiences a 15–20% decline in the first two years of retirement? Can you meet spending needs without selling growth-oriented assets at depressed values?
- How much of your portfolio is concentrated in assets that have performed well during the recent macro environment? And how might those assets behave if conditions shift?
- Do you have a liquidity buffer — cash or short-term reserves — that covers one to three years of essential expenses? That buffer can provide time for longer-term assets to recover without forcing premature distributions.
These aren’t exotic exercises. They’re the kind of planning conversations that tend to matter most before conditions change — not after.
Frequently Asked Questions
What is the U.S. Dollar Index and why does it matter to retirement investors?
The U.S. Dollar Index (DXY) measures the dollar’s value relative to a basket of major global currencies. Because many assets — including commodities, multinational earnings, and global financial flows — are influenced by the dollar’s direction, shifts in the index can affect the behavior of a broad range of investments that retirement portfolios typically hold.
How does a weakening dollar affect a retirement portfolio?
A weaker dollar has historically been associated with higher commodity prices and stronger reported earnings for U.S. companies with significant overseas revenue. However, it can also contribute to imported inflation and introduces its own set of risks. The net effect on any individual portfolio depends on asset allocation, sector exposure, and time horizon.
What is sequence of returns risk and why does it matter in retirement?
Sequence of returns risk refers to the impact that the timing of investment returns — not just the average return — can have on a retirement portfolio. A significant decline early in retirement, combined with ongoing withdrawals, can deplete a portfolio more than the same average return achieved in a more favorable order. This is why portfolio construction in the years surrounding retirement often differs from accumulation-phase strategies.
What is the Red Zone in retirement planning?
The Red Zone refers to the five years before and five years after retirement — the window where sequence of returns risk is typically most significant. During this period, a sharp market decline combined with income withdrawals may cause lasting damage to a portfolio that a longer time horizon might otherwise absorb.
Should I change my portfolio when the dollar is declining or strengthening?
Not necessarily — and attempting to time currency trends carries its own risks. The more useful question is whether your current portfolio is appropriately diversified and whether your near-term income needs are insulated from short-term volatility. A qualified financial professional can help evaluate your specific situation rather than making reactive changes based on short-term macro signals.
How do I know if I’m in the Red Zone?
If you’re within five years of your planned retirement date, or within the first five years of retirement, you’re in or near the Red Zone. This is typically a good time to review your income sequencing strategy, evaluate your liquidity buffer, and stress-test your plan against a range of market scenarios.
The Bottom Line
I don’t know with certainty whether the dollar breaks out of its current range or fades back in 2026. Nobody does, and I’d be cautious about anyone who claims otherwise. What I do think is that big macro trend changes — when they happen — tend to matter more to retirement timelines than the headlines suggest. Not because you need to trade around them, but because they’re a reminder to build a plan that doesn’t assume tomorrow looks like yesterday.
If you’re in your own Red Zone and haven’t run a stress test recently, it may be worth having that conversation before conditions shift rather than after. It’s generally easier to build resilience into a plan when you have time and options on your side.
Consider speaking with a qualified financial professional to review your retirement income strategy in the context of your specific goals, timeline, and risk tolerance. Individual circumstances vary, and general information is not a substitute for personalized guidance.
