You check EUR/USD before a trip to New York. The rate looks okay — about the same as last month. So you assume the Euro is doing fine.
But what if the Euro actually lost ground against the British Pound, Swiss Franc, and Japanese Yen during the same period? Is the Euro stable — or is the Dollar just equally weak?
This is why exchange rates alone are misleading. They only compare two currencies at a time. Currency strength compares one currency against all others simultaneously.
What is currency strength?
A currency strength index measures how a single currency performs against a basket of other currencies — not just one. Instead of looking at EUR/USD, you look at EUR vs. USD, GBP, CHF, JPY, CAD, AUD, and more — all at once.
The result is a single number that tells you whether a currency is broadly getting stronger or weaker.
On the FX Compass dashboard, a value above 100 means the currency has strengthened since the start of the selected period. Below 100 means it has weakened.
When your currency gets stronger
A strengthening national currency means your money goes further internationally:
- Travel: Your hotel in Bangkok, your rental car in California, your espresso in Rome — all become relatively cheaper
- Online subscriptions: If you pay for services priced in USD or EUR, a stronger home currency means lower real costs
- Imports: Electronics, clothing, and goods from abroad cost less in real terms
Real example: Imagine the Swedish Krona (SEK) strengthened by 8% against most major currencies over six months. A Swedish freelancer who earns in SEK and spends part of their income abroad just got an effective 8% raise — without any salary change.
When your currency gets weaker
A weakening currency has the opposite effect:
- Your purchasing power abroad shrinks — that vacation costs more than planned
- Import prices creep up — even domestic products that rely on imported materials
- Foreign-denominated debt becomes more expensive — relevant for countries and companies borrowing in USD
Why strength index beats a single exchange rate
Consider this scenario: The Polish Zloty (PLN) barely moved against the Euro in Q3 2024. Most Poles checking PLN/EUR would think nothing changed.
But the strength index showed PLN was actually one of the strongest currencies in the basket that quarter — gaining 3-5% against GBP, CHF, SEK, and HUF. The EUR was also strengthening, which masked PLN's real gains in the PLN/EUR pair.
Without the strength index, you'd miss this entirely.
How to use FX Compass for smarter decisions
-
Before traveling: Check your home currency's strength trend over the past 1-3 months. If it's rising, your trip will be cheaper than the exchange rate alone suggests.
-
Salary negotiations: If you earn in one currency and spend in another, track the strength gap between them. A widening gap means your real income is changing.
-
Big purchases: Buying a car imported from Germany? Check if EUR is weakening — you might get a better deal waiting a few weeks.
-
Saving in foreign currency: If you hold savings in USD or CHF, the strength index shows whether those savings are gaining or losing real value against your basket.
Open FX Compass and select your home currency plus the currencies that matter to you most. The chart will immediately show you the big picture.

The bottom line
Exchange rates are useful but incomplete. They show you one pair at a time, which can be deeply misleading. Currency strength gives you the panoramic view — how your money is really performing against the world.
And that's the kind of information that helps you make better decisions about travel, savings, contracts, and everyday spending.
