How much did currency movements affect my returns this month?
A currency question asks how much of a portfolio moves with an exchange rate rather than with the assets themselves. A fund priced in one currency can hold assets in several, so the exposure is rarely the currency on the ticket.
Worked through on a sample portfolio. The figures below are that portfolio’s, not yours.
You asked about currency movements for the month 01/09/2026–10/09/2026.
Table — sources of portfolio change this period
| Asset | Value change (€) |
|---|---|
| Portfolio total (period return) | -760,31 |
| Sum of holdings' owned value changes (market moves) | -682,15 |
| Currency & other effects (difference) | -78,16 |
What this means
- In the period 01/09/2026 to 10/09/2026 your portfolio fell by -760,31 € overall.
- Changes in the underlying holdings' prices accounted for a -682,15 € change.
- The remaining -78,16 € is the portion not explained by those owned-value changes — this captures currency movements and any small rounding/other effects for the period.
Notes
- I used the period snapshot for 01/09/2026–10/09/2026 and the holdings' owned value changes reported there.
- If you want a per-currency breakdown (EUR vs USD vs Crypto etc.), I can show which currencies contributed most to that -78,16 €.
