How does a PE fund handle currency risk in cross-border deals?

There are two layers: the operating-company exposure and the fund's equity exposure. Operating level: prefer natural hedges — match the financing currency to the cash-flow currency (borrow in EUR if the business earns EUR), so debt service and revenue move together. Fund/equity level: the sponsor's return is in the fund's currency but the investment is in the target's currency, so an adverse FX move can erode the euro/dollar return even on a good local result; this is hedged selectively with forwards or options on the equity value, or by funding via a cross-currency structure — weighing the (often high) hedging cost and the multi-year, uncertain holding period and exit timing. Many sponsors hedge the invested principal but leave the upside unhedged, and factor FX risk into the entry return hurdle. The discipline is deciding which exposures to hedge and accepting that perfectly hedging a 5-year private equity stake is rarely economic.
