The currency of your goals and the safe part at home

Every goal is measured in the currency it will be spent in. A car bought in Kyiv, school fees in Kraków, a flat deposit in Lviv: each has its own currency, and that is the currency the result must be counted in.

The user's goal: 500,000 UAH in 3 years, starting from 400,000 UAH. With round illustrative numbers (40 UAH per dollar today; a hryvnia deposit at 12% a year; taxes ignored), the deposit grows to:

400,000 × 1.12³ = 561,971 UAH,

61,971 above the goal, whatever happens to the dollar.

In real terms, with hryvnia inflation of 8% a year, 1.12 ÷ 1.08 − 1 = 3.7% a year above prices, and the 500,000 goal is worth 500,000 ÷ 1.08³ = 396,916 UAH in today's money. The deposit isn't exciting; it is simply in the right currency for this goal.

A dollar fund's result in hryvnias has two parts: what the fund did in dollars, and what the dollar did against the hryvnia.

Value in UAH = dollars invested × (1 + fund change) × exchange rate at the end.

With 10,000 dol. bought at 40 UAH:

• hryvnia holds (40): 10,000 × 1.191 × 40 = 476,400, short of the goal;
• loses 5% a year (40 × 1.05³ = 46.31): 10,000 × 1.191 × 46.31 = 551,552;
• loses 10% a year (40 × 1.10³ = 53.24): 10,000 × 1.191 × 53.24 = 634,088.

So the same fund misses or beats the goal depending on the exchange rate, a number nobody can forecast for three years. That's currency risk: exchange-rate moves change what an investment is worth in the currency you'll spend.

For a long goal, currency moves are part of a global fund's return. For a short goal, they are one more source of surprise.

A popular belief in Ukraine is that dollars "protect" savings. Against a falling hryvnia, holding dollars does help. But a dollar stock fund carries two risks at once, and they can hit together.

The ten scenarios show it:

• Deposit: 561,971, meets the goal in every case.
• USD cash: 400,000 / 463,100 / 532,400; meets the goal only if the hryvnia loses 10% a year.
• Fund, normal market: 476,400 / 551,552 / 634,088; misses it if the hryvnia holds.
• Fund, crash before the goal: 280,000 / 324,170 / 372,680; misses it in every case.

Only 4 of the 10 scenarios reach 500,000, and only one option reaches it every time. Devaluation can lift a fund that already did fine; it can't rescue a fund that fell 30% just before the money is needed.

For a goal three years away, the stock market's bad years are simply too likely to land on the wrong date.

A dollar stock fund held for a hryvnia goal has two separate risks:

1. Market risk: stocks can fall a lot in a year or two. In our synthetic 40-year history, world stocks once fell 45% over two years.
2. Currency risk: the hryvnia can hold, weaken slowly or weaken fast.

The two are not linked in any reliable way. Devaluation doesn't wait for good markets, and a crash doesn't wait for a strong hryvnia. Over three years you can get a crash with a stable hryvnia (280,000 UAH from 400,000), or a crash with a weak one (372,680): both miss the 500,000 goal.

Over 15–20 years, the picture changes: there is time for a fall to recover, and if the hryvnia weakens, that adds to a foreign fund's hryvnia result. That's why the same fund can be a poor home for a 3-year car and a reasonable one for retirement.

Money for a goal within a few years needs a home that won't fall when it's needed, in the spending currency. In Ukraine the usual candidates are deposits and government bonds. As of October 2027 (check the current rules):

• Deposits: interest taxed at 23% (18% income tax + 5% military levy), withheld by the bank. During martial law and for three months after it, deposits in Ukrainian banks are guaranteed in full; afterwards the guarantee is UAH 600,000 per person per bank, and currency deposits are paid out in hryvnias.
• Government bonds (ОВДП): issued in UAH, USD and EUR, 1,000 per bond; 0% income tax and levy for individuals. They are not deposits and not covered by the deposit guarantee fund. They can be sold before maturity, at a market price that may be below what you paid.

Always compare after-tax: the 12% deposit becomes 9.24% after tax and turns 400,000 into 521,441 UAH in three years. More on both in personal finance: Deposits and government bonds.

For each goal, two questions decide where the money lives:

1. When will it be spent? Within about five years, the money needs a home that can't fall far: deposits, short government bonds, cash for the cushion. Further away, a global stock fund can carry it, because there is time to wait out a crash.
2. In what currency? The safe part sits in the spending currency: hryvnias for a hryvnia goal, euros for euro fees. For a long goal, a global fund's currency moves become part of its return; that's acceptable when there are decades to absorb them.

So one person can sensibly hold a hryvnia deposit (car), euro bonds (studies) and a global fund (retirement) at the same time. That's not inconsistency; each pot matches its own goal.

The rule of thumb "five years" is a trade-off, not a law: a shorter horizon or a goal you can't move means more safety.

An investing app makes money when people invest. That creates a pull to send every goal to the fund. Resisting it is part of designing an honest product.

For short goals, the honest onboarding answer is often: this goal doesn't belong in stocks. Say why, with the numbers: in the ten scenarios, the dollar world fund reached a 3-year hryvnia goal in only 2 of 6 cases, the deposit in every case.

Good onboarding for a short goal:

• names the horizon and the currency back to the user;
• says plainly what can go wrong (a 30% fall just before the date);
• points to the kind of safe home that fits, without naming a bank;
• invites the user to set a longer goal in the app instead.

Users who were told "not this, not now" are more likely to trust the app with the goals that do belong there.

A user asking "why not just buy the dollar fund?" needs a short, numeric answer, not a lecture.

1. Name the goal's currency and date: hryvnias, three years.
2. Show the miss: if the hryvnia holds, the fund ends at about 476,400; if stocks fall 30% before the date, 280,000–372,680 whatever the exchange rate does.
3. Show the alternative: a hryvnia deposit at an illustrative 12% reaches about 561,971 before tax and 521,441 after the 23% tax; government bonds were untaxed as of October 2027.
4. Point to the right place: short hryvnia goals in hryvnias; the world fund for goals five or more years away.
5. Close honestly: illustrative numbers, not advice; check current rates and rules.

Name no bank. The user needs the type of home, not a brand.
