Unhedged vs Hedged ETFs (H): Cost and Currency Impact Explained
TL;DR
- Unhedged ETFs expose investors to the currency of the underlying asset, so exchange rate moves directly affect returns.
- Hedged ETFs (often marked with H) use dedicated hedging strategies to reduce currency risk. Which is preferable depends on exchange rate outlook and investment horizon.
Definition: Unhedged vs Hedged
An unhedged ETF passes the local-currency returns of the underlying asset through to the investor. For example, an ETF holding euro assets will reflect EUR/KRW moves in its KRW returns. A hedged ETF uses forward contracts, currency swaps, or similar tools to reduce currency volatility. In Korea, ETF names often include (H) or Hedged when a currency hedge is applied.
Why it matters
Exchange rates affect investor returns independently of the asset's underlying performance. The same foreign exposure can produce very different KRW returns depending on whether the won strengthens or weakens. Hedging can be more valuable for short-term horizons or when currency volatility is a concern, while keeping currency exposure may make sense for long-term diversification.
Common misconceptions
- Hedging does not 'increase' or 'guarantee' returns. It reduces return volatility from currency moves.
- (H) does not eliminate all currency risk. Hedge costs, rollover costs, and imperfect offsets remain.
- Unhedged exposure is not always 'too risky.' Over long horizons, currency movements can provide diversification when correlated with asset returns.
Calculation example (hypothetical numbers)
Assumption: local-currency return on the foreign asset is +5% in a year
- Unhedged case: if the underlying currency weakens 3% versus the won (KRW weakens), the KRW return is approximately 5% + 3% = 8%.
- Hedged case: if hedging costs 0.7% per year, the KRW return is approximately 5% - 0.7% = 4.3%.
This simple example compares hedging cost and currency effect by addition and subtraction. Actual hedging outcomes vary with contract terms, holding period, and rollover costs.
Comparison table: simple pros and cons
| Type | Advantage | Disadvantage |
|---|---|---|
| Unhedged | Potential extra return if currency rises | Larger losses if currency falls |
| Hedged (H) | Reduces currency volatility, more stable KRW returns | Hedging costs, cannot fully eliminate risk |
Checklist
- Clarify your investment horizon and exchange rate view first. Hedging may be more useful for short-term holdings.
- Check the ETF prospectus for hedging method and cost structure. Confirm specific cost figures from broker or issuer disclosures.
- Consider combining unhedged and hedged positions at the portfolio level. If needed, check holdings in 내 종목 레이더.
