Exchange-Rate Risk in Retirement: Protecting a Dollar Income Abroad

Here’s the retirement risk nobody stress-tests: you did everything right — saved diligently, moved somewhere affordable, budgeted carefully — and then the dollar drops 15% against the euro. Your portfolio didn’t change. Your spending didn’t change. Your standard of living just took a pay cut anyway.

Why retirees feel currency moves hardest

A working expat has options when rates move: earn more, adjust, wait it out. A retiree drawing fixed dollar streams — Social Security, IRA withdrawals, pension payments — into a euro life absorbs the move directly. And currency cycles are long: the dollar has swung 20–30% against the euro over multi-year stretches several times since the euro’s birth. A retirement lasting 25 years will see both directions. The plan has to survive both.

Five defences, from easiest to strongest

1. The euro buffer

Keep 12–24 months of living expenses in euros (a retiree’s version of the three-bucket system). When the dollar is weak, spend the buffer instead of converting at bad rates; refill when it recovers. This single habit smooths most cycles.

2. Convert on schedule, top up opportunistically

Automate quarterly conversions for averaging, and add opportunistic top-ups via rate alerts when the dollar is strong. Cheap execution matters doubly on repeated transfers — never pay bank spreads.

3. Flex the withdrawal source

Retirees with multiple pots (traditional IRA, Roth, taxable) already choose which to draw for tax reasons; add currency to the logic. In weak-dollar years, draw the minimum and lean on the euro buffer; in strong-dollar years, convert extra and refill. Coordinating this with RMDs and tax brackets is genuinely valuable — and genuinely a job for a cross-border fee-only advisor.

4. Consider some euro-denominated substance

Some retirees hold a slice of assets that are euro-linked by nature — most commonly the home they live in. Owning your European home converts your biggest euro liability (rent) into a euro asset; it’s as much a currency decision as a lifestyle one. (Buying with US funds? Sequence the conversion — see defence 2 — and read the full retirement money picture.)

5. Budget honestly with a stress test

Run your budget at a rate 15% worse than today’s. If it still works, sleep well. If it doesn’t, the answer is usually a cheaper housing choice or destination — found before the move, not after. Our free calculator makes the first pass easy.

What 2025 did to a dollar retiree

This isn’t hypothetical. The euro opened 2025 at about 1.03 dollars and closed it at about 1.17: the dollar lost roughly 12–13% against the euro in a single calendar year. A retiree converting a fixed dollar income every month bought noticeably fewer euros in December than in January, with no change in the portfolio, the pension or the budget.

Notice how close that is to the 15% stress test in defence 5. A year like that is not a black swan; it is a normal feature of a long retirement, and the reason the euro buffer exists. Anyone holding 12–24 months in euros at the start of 2025 simply spent them and waited. The other direction happens too, and feels like a windfall — which is exactly when to refill the buffer instead of upgrading the car.

Social Security in euros: the deposit and the COLA

Social Security can be paid straight into a bank account in many countries, or keep landing in your US account for you to convert. The first is convenient; the second gives you the rate and the timing. If the payment lands abroad, the conversion happens at whatever rate sits in that pipe on that day, every month, with no averaging and no buffer logic. If it lands in the US, it joins the schedule in defence 2 — the better machine for most retirees.

Two details worth knowing. The annual cost-of-living adjustment applies identically abroad — 2.8% for 2026 — but it tracks US prices, not euro prices and certainly not the exchange rate, so it will never rescue you from a currency move. And the SSA sends beneficiaries abroad a proof-of-life questionnaire (form SSA-7162) every year or two; if it isn’t returned, payments stop. Keep the SSA address one where post reaches you (Social Security abroad, in full).

Sequencing the year’s withdrawals

Defences 2 and 3 work best as one annual routine rather than a series of decisions:

• January: set the year’s euro spending target and check the buffer against it. If it already holds 12–24 months, this year’s conversions are only a refill.
• Each quarter: convert a fixed dollar amount regardless of the rate. The averaging is the point.
• When the dollar is strong: convert extra and push the buffer to the top of its range. This is the only time to be greedy.
• When the dollar is weak: draw the minimum you must (required minimum distributions start at 73, or at 75 if you were born in 1960 or later) and let the buffer carry the shortfall.

Taking the whole year’s withdrawal in one January lump locks a year of spending to a single day’s rate; spreading it fixes that without any forecasting. Coordinating the spread with tax brackets, the taxable share of Social Security and any Roth conversions is where a cross-border advisor earns the fee.
