ARMFHedging risk
Hedging risk means opening a position that offsets the loss on an existing one. On the currency market the technique is often used instead of a stop, and in that form it does not protect but postpones the decision while adding costs. We take apart where a hedge makes economic sense and where it is only an appearance of one.
What hedging currency risk means in trading
In its original meaning, hedging is protection of a future cash flow from a change in the exchange rate. An exporter who will receive revenue in euros in three months sells euros forward and fixes the rate: they give up a possible gain in exchange for certainty.
In retail trading the term is used differently: as opening an opposite position in the same instrument. The economic meaning then almost disappears — and it is worth understanding why.
| A hedge as protection of a flow | A «lock» instead of a stop | |
|---|---|---|
| What is protected | A future currency conversion | The floating loss on a position |
| Is there an underlying asset | Yes, a real flow | No, only an open trade |
| What is fixed | The rate of a future operation | The current loss |
| Cost | The spread and the cost of the instrument | A double spread and swap on both sides |
| When it ends | At the moment of the real operation | By a decision that has been postponed |
Why a «lock» does not solve the problem
Opening an opposite position of equal size fixes the loss at the current level: further moves do not change the combined result. But you cannot leave that state without a cost either — closing one of the sides returns the account to the original situation, only now with double the costs.
A simple check. Ask yourself: «If the position did not exist, would I open it right now in this direction?» If the answer is no — the trade has to be closed, not locked. A lock preserves a position you no longer believe in and adds a second one to it.
When a hedge is genuinely justified
There are situations where an opposite position solves a task that closing cannot solve.
Future income or expense in a foreign currency: fixing the rate protects the planned amount, not the trading result.
the original meaningA position in a correlated pair in the opposite direction reduces the total bet on a currency when closing individual trades is undesirable for strategic reasons.
reducing the betRare cases where closing is impossible or more expensive: for example, under venue restrictions. Then a hedge is a temporary solution with a known price.
an exceptionIn all three cases a hedge is a deliberate trade with a calculated cost: it is known how much it costs in spread and swap, and it is known when it will be closed. If there is no answer to the second question — it is not a hedge but a postponed decision.
How much a «lock» costs: the calculation in numbers
The cost of the construction is usually underestimated because it is spread out over time. Let us calculate it for a position of 0.5 lot of EUR/USD held for a month: a spread of 1.5 pips, a negative swap of $1.20 per night on 0.5 lot on each side.
| Item | A single close at the stop | A «lock» for a month |
|---|---|---|
| Spread on entering the second position | — | $7.50 |
| Swap for 30 nights | — | about $72 |
| Spread on closing both positions | $7.50 | $15 |
| The fixed loss | as calculated at the stop | the same one |
| Total on top of the loss | $7.50 | about $94.50 |
The swap values are model ones: they depend on the pair, the direction and the broker's terms, and have to be looked up in the instrument specification. The order of magnitude holds, though — over a month of holding two opposing positions the amount adds up to several spreads.
The main thing in this table is the last row: for a month of waiting you pay roughly twelve times more than a simple close of the position would have cost. And that is with the fixed loss being identical in both cases.
Frequently asked questions
What is hedging risk in simple words?
It is a trade whose loss offsets the profit on another one, and the other way round. Its point is not to earn but to make the result predictable: you give up part of a possible gain in exchange for certainty.
Do brokers allow hedging?
It depends on the position accounting mode: in hedging mode you can hold opposite positions in the same instrument, in netting mode they collapse into one. The mode is stated in the account terms and determines whether a «lock» is technically possible.
Which is cheaper — a lock or a stop-loss?
A stop-loss. It closes the position once and pays the spread once. A lock leaves both positions open, pays the spread twice and adds a swap for every day of holding — with the same fixed loss.
Does a lock free up margin?
It depends on the broker's accounting mode. In hedging mode opposite positions often require margin only on the larger side, in netting mode they collapse into one. But even freed margin does not cancel the double costs.
Can a position be hedged with another currency pair?
It can, and that makes more sense than a «lock»: for example, a long EUR/USD is partly offset by a long USD/CHF. But the protection is incomplete — the pairs are not rigidly linked, and the residual risk is counted by their actual correlation.
What is cross-hedging and when does it apply?
Protecting a position with an instrument that correlates with it but is not the same. It applies when a direct close is undesirable or impossible; the price is the residual risk of divergence between the instruments.
Is swap risk hedged?
Usually not: the swap is a fee for holding rather than market risk. «Hedging» it with an opposite position gives a negative amount on both sides, because the rates for buying and selling are not symmetrical.
Does an intraday trader need a hedge?
Practically never. The position lives for hours, and any deterioration is closed by a stop more cheaply than by an opposite trade. A hedge makes sense where there is a future currency flow or long-term exposure.
Does an opposite position of a smaller size count as a hedge?
That is a partial close dressed up as a second trade. Economically it is simpler to reduce the original position: the result is the same, the spread is paid once and the swap is charged on one side.
How do you know that a «hedge» is really a postponed decision?
By the answers to two questions: is the date or the condition for closing the construction known, and has its cost in spread and swap been calculated. If at least one answer is missing, it is not a hedge.
