What it means
Every financial position can be undone by taking the opposite side of the same deal. If a business buys 1,000 shares, the inverse transaction is to sell those 1,000 shares, and if it sells a currency forward, the inverse is to buy the same amount of that currency for the same date.
The result is that the original exposure is closed, and what remains is the profit or loss. The term is not a tightly defined technical label in accounting standards, so it is worth asking what a colleague means.
In trading it usually means closing or offsetting a position. In bookkeeping it can mean a reversing entry, where an earlier journal is cancelled by posting the same amounts on opposite sides.
Inverse transactions matter because they turn an unrealised result (a gain or loss that exists only on paper) into a realised one. Once the opposite trade is made, the gain or loss is fixed and usually becomes taxable or deductible.
Timing of the inverse transaction can therefore affect which accounting period or tax year the result falls in. They are also central to risk management.
A company that hedges a foreign currency receivable does so by entering a contract that moves in the opposite direction to the exposure, and the contract can later be closed with an inverse transaction. The cost of closing is the difference between the original and closing prices, plus any fees.
One nuance is that an inverse transaction rarely restores the starting position exactly. Prices have moved, fees have been paid, and sometimes interest or financing costs have accrued, so the net result is almost never zero.
In practice
Real-world examples.
Example
A distribution company has bought forward euros to pay a supplier, but the supplier invoice is cancelled. The treasurer sells the same euro amount for the same date, which is the inverse transaction. The gain or loss on the pair is the difference between the two forward rates.
Example
A portfolio manager holds 5,000 shares of a bank and decides to exit the position. She sells all 5,000 shares in the market, which closes the position and realises the profit that had previously existed on paper.
Example
An accountant posts an accrual of $12,000 for unbilled consulting work at month end. On the first day of the next month she posts the inverse entry, debiting and crediting the same accounts in reverse, so the accrual does not double count when the invoice arrives.
Formula
Calculation
Profit or loss on a closed long position = (closing price - opening price) x quantity - total transaction costs
A company buys 1,000 shares at $20 per share, paying $20,000 plus $25 in fees. Later it makes the inverse transaction and sells all 1,000 shares at $23, receiving $23,000 less $25 in fees. Gross gain = (23 - 20) x 1,000 = $3,000. Total fees = 25 + 25 = $50. Net profit = 3,000 - 50 = $2,950.Case study
Seen in the real world.
Kestrel Imports is an illustrative, fictional company that buys machinery parts from abroad. It agreed a forward contract to buy 500,000 euros at an exchange rate of $1.10 per euro, a $550,000 commitment, to pay a supplier in three months.
When the supplier cancelled the order after one month, the treasurer entered the inverse transaction by selling 500,000 euros forward at $1.12. The company therefore received $560,000 against the $550,000 it had committed to pay, a gain of $10,000, before bank fees.
The illustrative lesson is that the inverse trade did not erase the history: it locked in a result that depended on how the exchange rate moved in the meantime. Had the rate fallen, the same step would have fixed a loss.
Watch out
Common mistakes.
- Assuming an inverse transaction returns the business to exactly where it began, when price movements, fees and financing costs mean there is almost always a gain or loss.
- Forgetting that closing a position realises the profit or loss, which can create a tax charge or deduction in that period.
- Using the phrase without checking whether the other person means a trading offset or an accounting reversing entry.
Questions
People also ask.
Is an inverse transaction the same as a hedge?
Not exactly, because a hedge is taken to protect an exposure, while an inverse transaction is any trade that reverses an earlier one, though a hedge can be closed this way.
Does an inverse transaction always produce a gain?
No, it fixes whatever the result is, and if the price has moved against the original position it fixes a loss.
How does a reversing journal entry relate to this?
It is the bookkeeping version, where an earlier entry is cancelled by posting the same amounts on opposite sides.
