Investing and allocating capital
How Should a Family Decide Whether to Hedge Foreign Currency Risk?
Short answer. Start by identifying which assets, spending needs, and future cash flows are exposed to currency movements. Then decide whether the exposure fits the family's plans or creates volatility it cannot accept. A hedge can reduce uncertainty, but it has costs and should follow a clear policy instead of a forecast about currency direction.
Decide whether to hedge by mapping your currency exposure to the family's actual obligations and investment horizon. A foreign asset can rise or fall in value when translated into the family's home currency, even when the underlying investment has not changed. The relevant question is how that movement affects the family's capacity to spend, meet commitments, and stay with its investment plan.
Map the Exposure First
Separate exposure into cash flows that are due, assets held over time, and longer-term economic exposure. A scheduled payment in a foreign currency creates a different planning problem from an investment held for many years. Record the currency, timing, and purpose of each material exposure, along with any local currency income or liabilities that already offset it.
Look at the whole portfolio and the family's future spending. If assets and liabilities in different currencies naturally offset one another, a hedge may add cost without solving much. If a currency decline would make it harder to fund a known obligation, reducing that risk may matter more than preserving every bit of upside from a favorable exchange move. The family's portfolio model can clarify how these holdings fit together.
Set a Policy Before Choosing a Tool
Write down which exposures qualify for hedging, who can approve a hedge, and how results will be reviewed. Define the purpose as reducing uncertainty around a specific exposure, not predicting where exchange rates will go. A policy can also distinguish between cash flow protection and the currency exposure accepted as part of a long-term investment.
Forward contracts, futures, options, swaps, and money market techniques can be used in different situations. Their terms and obligations differ. A futures contract obligates the holder to transact on a set settlement date, while an option gives a right without an obligation at a predetermined price. The choice depends on the exposure, timing, cost, and the family's ability to manage the instrument. Keep the approval process and documentation aligned with the family's governance policies.
Review the Hedge Alongside the Portfolio
Measure whether the hedge reduced the exposure it was meant to address, including its costs and any remaining risk. Avoid judging a hedge only by whether it made money. A hedge can do its job even if the currency later moves in the other direction, because its purpose was to reduce uncertainty around a planned cash flow or investment value.
Review exposures when the family's holdings, liabilities, or spending plans change. A simple currency schedule tied to reporting periods can help staff spot mismatches before they become urgent. The currency exposure across global assets page and the liquidity plan across investment horizons can help frame that review. For legal, tax, or contract details, talk with your attorney or CPA.
The diversification of a currency portfolio, whether based on a complex model or gut feeling, is always less risky then holding one currency.
