Multi-currency, the honest way
A portfolio held in multiple currencies — Apple in USD, an ETF in EUR, a real-estate position in GBP — only reports honestly if the conversion to your reference currency uses the historical FX rate of every transaction. Anything else quietly rewrites history.
Evibe does this correctly by default. Each portfolio has its own reference currency (USD, EUR, GBP, CHF, anything we cover). For every transaction, the FX rate on that day is locked in. Cost basis in your reference currency is the sum of those locked-in costs. Performance figures reflect the actual currency journey of the position, not a today's-rate retro-projection.
Why "historical FX" matters
A concrete example: a European investor buys 10 Apple shares at $200 in January 2019 (EUR/USD = 1.13). They sell five years later, with AAPL at $250 and EUR/USD = 1.08. Two ways to report the return in EUR:
- Today's-rate-retroactive — cost = $2,000 / 1.08 = €1,852; value = $2,500 / 1.08 = €2,315; return = +25%.
- Historical FX on cost basis — cost = $2,000 / 1.13 = €1,770; value = $2,500 / 1.08 = €2,315; return = +30.8%.
Both calculations claim to express the same euro return; only the second is what actually happened. The position generated +5.8 percentage points of additional return from the FX move alone. The first method silently absorbs that into "return," then loses track of where it came from.
Evibe always reports the second number, and separately surfaces the FX contribution to the return so you can see how much of your performance came from the underlying vs. the currency.
70+ currency pairs, continuously
The FX engine tracks every major pair and most minor ones — EUR/USD, GBP/USD, USD/JPY, USD/CHF, EUR/GBP, AUD/USD, NZD/USD, USD/CAD, plus the long list of cross-pairs needed for accurate conversion in a real-world portfolio.
For each pair, historical daily rates back to 2000 (or the earliest reliable source for the pair) are stored, so even older transactions get the correct conversion.
Per-portfolio reference currency
Each portfolio carries its own reference currency. A common setup: one portfolio in EUR for the European brokerage account, one in USD for the US one, both visible in the same app, each reporting honestly in its own anchor. The aggregate net-worth view then converts both into your chosen display currency, again with historical FX for the cost basis.
What this is not
Evibe is not a forex trading platform. We don't offer FX hedging instruments or currency forwards. The multi-currency engine exists to report on a global portfolio correctly, not to let you trade currencies.
