Calculating the Return on Risk for a Hedged Forex Position

For Australian traders running multi-leg positions across the AUD crosses, whether a hedge pays its way is rarely answered by a simple risk-to-reward ratio. The Return on Risk, or RoR, reframes the question around capital at stake. Hedging adds a second layer because the protective leg's cost comes out of the same profit pool.

ASIC-regulated brokers publish tight spreads on AUD pairs but charge overnight swap on hedged legs, so the running cost can quietly eat into returns. Sydney and Melbourne traders who scalp during the Asian session also face liquidity gaps that change realised risk.

Two legs that each show a 2:1 reward against their own stop look attractive, yet combined they often deliver a fraction of expected return once spread, swap and correlation drag are included. RoR forces those costs into the same denominator as the upside, which is why risk-aware traders in Brisbane and Perth use it as a check.

This guide covers hedged position components, the formula, and a worked AUD example. It also addresses sizing mistakes on the protective leg's stop and ends with pre-trade habits.

What Return on Risk Actually Measures

Return on Risk expresses profit as a percentage of capital genuinely exposed to loss. The basic form is RoR = Net Profit ÷ Total Risk Capital, where risk capital includes both the open trade and the hedge. A trade returning $400 on $1,000 of combined risk shows an RoR of 40 percent.

The metric matters when two legs interact. A long AUD/USD against a short NZD/USD is a positive-carry play, but the positions partially cancel in dollar terms. RoR captures the net result after that cancellation. The same disciplined approach that helps traders when spotting genuine project updates translates across asset classes.

For hedgers, RoR is useful because the protective leg usually carries a smaller target than the primary leg. Without a shared denominator, traders can convince themselves a tight, profitable hedge proves the system works, when in fact the original thesis paid the bill and the hedge merely trimmed the bleed.

Anatomy of a Hedged Forex Position

A hedged spot position involves two currencies expected to move in offsetting directions. The most common structure for an Australian trader is long AUD/USD while short AUD/JPY, capturing the spread between the two JPY-sensitive quotes. Another version pairs a long commodity currency with a short safe haven, such as long AUD against short CHF.

Each leg has its own stop, target and running cost. The hedge leg carries a tighter stop because it is defensive, while the directional leg holds the larger profit. When AUD/USD and AUD/JPY rise together on a strong Australian dollar, the hedge stops behaving like a hedge. The same statistical mindset behind a low-correlation crypto portfolio applies to a two-leg currency hedge.

Swap and spread are hidden inputs. AUD/JPY often carries a positive overnight swap for the long side, while the USD leg is close to neutral. Both must be added to the risk denominator if the hedge lives longer than a single session, common for Sydney-based swing traders.

The Core Formula for a Hedged Trade

The working formula is:

RoR = (Profit from directional leg − Cost of hedge leg) ÷ (Risk of directional leg + Risk of hedge leg)

The numerator captures net realised profit after subtracting everything the hedge consumed: spread paid twice, swap accrued and any small loss on the protective leg when it did its job. The denominator adds the dollar amount each leg stood to lose at entry.

Melbourne desk example: long one lot of AUD/USD at 0.6600, stop 0.6570 (300 USD risk); short AUD/JPY at 95.20, stop 95.50 (another 300 USD). Total risk capital 600 USD. AUD/USD rallies to 0.6640 (400 USD profit); AUD/JPY drifts to 95.32 (120 USD cost). Net profit 280 USD, RoR 46.7 percent.

If the same trader had taken only the AUD/USD leg with a clean 2:1 setup, the headline R:R would have looked better, but the RoR figure makes clear the protective leg gave up some profit to do its job.

Choosing Pairs That Actually Hedge

A hedged position only earns its keep when the two legs genuinely move in opposite directions most of the time. Correlation between currency pairs is not fixed; it shifts with interest rate cycles, commodity prices and central bank rhetoric. The AUD/USD and NZD/USD pair, often a textbook correlation trade, decouples when Australian employment data surprises.

Testing matters before the trade goes live. A 30-day rolling correlation between AUD/USD and AUD/JPY often sits at 0.6 to 0.8 in quiet markets but collapses toward zero around RBA meetings, when the hedge should matter. Traders holding these positions through the Sydney close should treat any figure below 0.5 as a yellow flag.

The safe haven half deserves equal scrutiny. AUD/CHF is a popular defensive pair, but Swiss National Bank interventions can flatten the relationship overnight. Recording correlation separately for high- and low-volatility weeks gives a clearer picture.

Hedging Effects on the Risk Side of RoR

The denominator is where hedges most often get miscounted. Traders routinely include only the directional leg's stop distance and forget to add the hedge's exposure, which inflates RoR by ignoring real capital at risk. If both legs use 1 percent of the account, the combined exposure is 2 percent, not 1.

Correlation can also reduce effective risk below the simple sum. When two pairs move in opposite directions, the worst-case session loss is usually lower than the sum of the two stops, since both legs rarely hit their limits on the same candle. A Brisbane trader working around an RBA press calendar will recognise this: days of AUD volatility spikes push both legs the same way, when the hedge is least useful.

Swap is the third distortion. A hedge running through a Wednesday rollover on a high-carry pair can add measurable drag to the opportunity cost. Including that cost in the risk figure keeps RoR honest.

Comparing a Hedge and a Direct Trade

Dimension	Direct AUD/USD long	Hedged long AUD/USD / short AUD/JPY
Risk capital at entry	Stop distance × pip value	Sum of both stops × pip values
Max loss on a black swan	Single stop hit	Smaller in calm weeks, larger if correlation breaks
Running cost per day	Swap on one pair	Swap on both legs, often offsetting
Typical RoR range	25% to 60% on a clean 2:1	15% to 40% once hedge costs included
Psychological load	One position
