Allocation & Exposure
Currency Exposure
Definition
The portion of the portfolio whose value changes when exchange rates move even if no currency conversion has taken place.
Why it matters
Currency moves affect the portfolio even when you do not trade in foreign currencies. Holding a USD-denominated ETF in a EUR portfolio is a currency position.
What most investors miss
The gap between what the term means and how it is usually applied.
They focus on price return and ignore FX return. In a globally diversified portfolio currency can be the largest single source of return variance.
How to read it
Identify which portion of the portfolio is exposed to each currency. Then decide whether that exposure is intentional or accidental.
Multi-account lens
How this term reads differently across brokers and accounts.
Currency exposure compounds across accounts when each broker reports in a different base currency. Consolidation with a fixed FX basis is the only way to read it accurately.
