Hedging Currency Exposure for Small Accounts

Hedging means holding a second position that offsets the risk of the first. In large institutions it is a daily necessity. For a small trading account it is sometimes useful and often a way of avoiding a decision. Knowing the difference saves money.

The simple version

If you are long the euro against the dollar and you open a short of the same size on the same pair, you have no exposure and you pay two spreads and two swaps for the privilege. This is called a direct hedge, and it is almost always worse than closing the trade. The only honest reason to do it is a platform restriction that prevents closing, which is rare.

The partial version

A more useful form is to hold two positions that partly offset each other. Long the euro against the dollar and short the pound against the dollar, for example, leaves you with a net position in the euro against the pound and a reduced dollar exposure. This is not really hedging; it is choosing a different exposure. It is worth doing only if the euro against the pound is the trade you actually want.

When a hedge helps

• You hold a long-term position you do not want to close, and a short-term event threatens it; a short-term opposite position through the event can protect the long-term one at a known cost
• You have a position in a currency that is about to face a central bank decision, and you want to reduce size without closing because the spread on re-entry would be wide
• You hold exposure through an account in another currency and want to stop currency moves from changing your account value

In each case, the hedge has a defined start, a defined end and a cost you have calculated.

When it hurts

The common failure is hedging a losing trade instead of closing it. The loss is frozen, two positions now cost swap, and the trader must later decide which leg to close, which is the decision they avoided in the first place. A hedge that has no exit plan is a loss that has been renamed.

For most small accounts, the better tool is size. If a position is too large for an event, reduce it. If the risk is uncertain, hold less. Hedging adds complexity; sizing removes it.

What to watch

Watch the total cost of any hedge in spread and swap, the exit plan for each leg, and whether the hedge is protecting a plan or protecting you from a decision. If you cannot say when the hedge will be removed, close the original trade instead.
