FX Transaction Risk vs FX Translation Risk

Transaction exposure is cash actually changing by a different amount than expected, and it reaches profit. Translation exposure restates a balance already held, and it does not. At Vindhya Commercial Bank Limited, invented, a 5.0 per cent move on a Rs 480 crore branch investment moves a reserve by Rs 24 crore and touches no profit, and at Nirjhar Industries Limited, invented, Rs 4.03 crore does.

Two currency exposures sit in this case, and one of them is nearly two and a half times the size of the other. Ranked by size, the wrong one draws the worry. The mismatch is not a trick of presentation, and it is not an accounting quirk to be waved away. The ranking follows from a single question that can be put to any currency exposure at all: is cash going to move, or is a number going to move? Everything in this guide is the consequence of that one question, and by the end the answer takes about four seconds for an exposure never seen before.

What is a transaction exposure, and what is a translation exposure?

Half the confusion in this subject comes from readers who met one of the two first and quietly assumed the other was a variation on it. Define both, then compare them. Transaction exposure and translation exposure are not variations on each other. The two are different kinds of thing that happen to share the word exposure and the word currency.

A transaction exposureAn obligation or a receipt in another currency whose amount in the reporting currency is not yet fixed, so the cash that actually moves may differ from the cash that was expected. is an obligation the entity has taken on, or a receipt it is expecting, denominated in a currency other than the one it reports in, where the rupee amount has not yet been fixed. The entity has agreed to pay a number of dollars. The rupee cost depends on where the currency sits on the day the money actually leaves, so the number of rupees stands unagreed. The defining feature of a transaction exposure is that real cash is going to move and nobody yet knows exactly how much of it.

Here is the household version, and it is worth holding on to. Somebody has booked a wedding hall for a cousin studying abroad and agreed the fee in a foreign currency, payable in three months. The hall is booked. The number of foreign currency units is fixed. The rupee sum the household will actually hand over is not fixed, and the household discovers it on the payment day. Whatever the difference turns out to be, it is money the household either has or does not have. A booked hall with an unfixed rupee cost is a transaction exposure, complete, at wedding scale.

A translation exposureA balance already held in another currency being restated into the reporting one, where nothing moves except the number. is a different animal entirely. The entity already holds something: a branch, a subsidiary, a business unit, whose books are kept in another currency. Nothing about it is being bought or sold and no payment date exists. But when one set of accounts is produced for the whole institution, that holding has to be expressed in the reporting currency, and the number it is expressed as depends on where the currency sits on the reporting date. The defining feature of a translation exposure is that nothing moves at all except the number in the accounts.

The household version again. Take the same household, owner of a small plot of land in another country held for years with no intention of selling. Every year somebody writes down what it is worth in rupees, and every year that figure changes, partly because land prices moved and partly because the currency moved. Nobody has gained or lost a rupee of spending money. The plot is exactly as big as it was. The only thing that changed is the sentence in which the household describes the plot. A plot whose rupee description moves while the plot itself does not is a translation exposure.

What actually moves in each one, and where does the movement land?

What moves and where it lands are the first two of six differences, and they carry the other four. Take them one at a time.

On what moves, the separation is total. In a transaction exposure, money leaves the building, or arrives at it, in a quantity nobody could pin down in advance. The difference between what was expected and what happened is real money. The money is spendable, or it is gone. In a translation exposure nothing leaves and nothing arrives. The holding is the same holding it was yesterday, the same size, the same business, the same people in it. The only change is in the arithmetic of describing the holding in a different currency. One exposure changes the bank balance and the other changes the sentence.

On where it lands, the consequence follows immediately. A difference in real cash has to show up as a gain or a loss for the period in which it happened, so it reaches the profit and loss accountWhere a transaction exposure lands when it settles, and the place a translation exposure never reaches.. A restatement of something already held has not made the entity better or worse off in the period. The movement is parked in a translation reserveThe line inside equity that carries the effect of restating an overseas balance. A movement there does not reach profit. inside equity instead, and it sits there until the holding itself goes. The comparison is complete in one line, and everything that follows either elaborates it or guards against misreading it.

The remaining four differences are worth having in one place, so here they are as rows. Read the middle column as the transaction side and the right column as the translation side.

What is measured, over what horizon, and what does a policy do about each?

Axis three is about the input required before anything can be computed at all. For a transaction exposure the input is an amount and a date: so many dollars, due on such a day. An amount the entity is already contracted to is a committed exposureAn obligation the entity is already contracted to, with an amount and a date. The invented group's payable is one., and being contracted is what makes it measurable rather than a guess. For a translation exposure the input is a net investmentA parent holding in an entity or a branch reporting in another currency, being Rs 480 crore at the invented bank and Rs 288 crore at the invented group.. A net investment is what the parent holds in the entity or the branch once everything inside it has been netted off. A transaction exposure cannot be computed without a date, and a translation exposure does not have one.

Axis four falls straight out of that. A transaction exposure has an ending built into it. The payment day comes, the cash moves, the difference is booked, and the exposure is gone. A translation exposure has no such day. The invented bank has held its overseas branch for years and will hold it for years more, and every reporting date for as long as it does, the same restatement happens again. Practitioners sometimes say the transaction one is sharper and the translation one is longer, and that is a fair summary as long as sharper is not allowed to turn into more important.

Axis five is where this case gets specific. The general version is where readers invent things. Be exact rather than general. The invented group's treasury policy sets treasury limit TL3, a hedge floorThe minimum share of a committed exposure the invented group's own policy requires to be covered, being 60.0 per cent here. requiring at least 60.0 per cent of a committed foreign currency exposure to be covered. The floor is the group's own board policy, and nobody handed it down as a requirement. Against the two translation exposures in this case, the policy says nothing at all, and the case records no notional, no ratio and no instrument against either of them. One kind of exposure in this case is covered to a policy floor and the other kind is entirely uncovered, and that silence is stated here rather than filled in with an invented hedge.

What happens to each one when the currency moves back?

Axis six is the one readers most often have not thought about, and it changes how each exposure should be treated in a report. A transaction exposure is a one-way door. Once the payment day arrives and the cash moves, the difference is booked and it is finished. If the currency comes all the way back the following week, that is a fact about next week and it does nothing whatever for the period that just closed. SettlementThe moment a transaction exposure ends and its effect becomes final, which a translation exposure has no equivalent of. is what makes the number final.

A translation exposure is a two-way door and stays one for as long as the holding is held. If the currency moves one way this reporting date and back the next, the reserve moves out and back again, and nothing has permanently happened to anybody. A transaction effect is realised and a translation effect is not, so one of them touches profit and the other does not. The word realised is doing real work there, and it is the shortest honest answer to why the treatment differs.

How does the translation exposure work at the invented bank?

Vindhya Commercial Bank Limited, invented, holds a net investment of Rs 480 crore in one overseas branch. The branch keeps its books in a currency that is not the rupee, and the bank reports in rupees, so on every reporting date the branch has to be expressed in rupees at whatever the currency is doing that day.

Apply the bank's own scenario, a 5.0 per cent move in the rupee against that currency. The size of that scenario is the bank's own invented figure and is not a statement about any currency anywhere. Rs 480 crore times 5.0 per cent is Rs 24 crore. The Rs 24 crore goes to the translation reserve inside equity, and the profit and loss account for the period does not change by a single rupee.

This case is large enough that figures repeat. Name the object every time. Rs 24 crore here is a translation reserve movement at the bank. The same figure elsewhere in this case is counterparty C1's potential future exposure, and it is also position FX4's Japanese yen short in the currency position set. Three completely different things wearing one number, and a reader who sees Rs 24 crore and assumes it is the one they met last has just merged two records that have nothing to do with each other.

How does the transaction exposure work at the invented group?

The second invented entity sits across the table. Nirjhar Industries Limited, invented, is a steel and alloys maker and the parent of a three entity group. One of those entities buys in United States dollars (USD) while the group reports in rupees, and a payable of USD 24 million falls due in 90 days. The group booked the payable at its own contracted rateThe Rs 84.00 the invented group booked its payable at. The rate is the group's own figure rather than a market rate. of Rs 84.00 to the dollar, a rate the group set for itself rather than read off a market.

Four lines of arithmetic settle it, and each line is a decision somebody actually took rather than a formula. USD 24 million at Rs 84.00 is Rs 201.6 crore. A 5.0 per cent adverse move on the whole payable is Rs 10.08 crore. Treasury limit TL3 requires at least 60.0 per cent cover, so Rs 120.96 crore is covered and Rs 80.64 crore is the open partThe share of an exposure left uncovered after the policy has been applied, being Rs 80.64 crore of the invented group's payable.. Five per cent of that open part is Rs 4.03 crore. The Rs 4.03 crore reaches the profit and loss account in the period the payable settles, in full, and no reserve anywhere could take it instead.

Does the larger exposure produce the larger effect on profit?

The two set side by side answer it properly, and this is the payoff of the whole comparison. Rs 480 crore of exposure at the invented bank produces a Rs 24 crore movement, and not one rupee of that reaches profit. Rs 201.6 crore of exposure at the invented group produces a Rs 10.08 crore movement, of which Rs 4.03 crore reaches profit. The larger exposure produces the larger number and touches no profit at all. The smaller one produces the smaller number, and part of it lands in the income statement in full.

Compare the open parts rather than the headline exposures and the shape is even cleaner. The bank has Rs 480 crore open and the group has Rs 80.64 crore open. Six times the open exposure produces very close to six times the movement, Rs 24 crore against Rs 4.03 crore, with none of the consequence attached to the bigger of the two. There is one more per rupee reading worth keeping: at the 60.0 per cent floor, 2.0 per cent of the group payable reaches profit on a 5.0 per cent move, being 5.0 per cent of the 40.0 per cent left open, and 0.0 per cent of the bank exposure does.

What does the whole curve look like as the move gets bigger?

Intuition suggests that if the move were big enough the reserve effect and the profit effect would eventually meet, or at least that their relationship would shift. Neither happens. Both effects are the same exposure multiplied by the same percentage, so both are straight lines through the origin, and the only thing separating them is the slope. Five solved points follow, and the last column is what makes the case.

The ratio is fixed at Rs 480 crore over Rs 80.64 crore, being 5.95 times, at every move size on the scale, so the two lines never meet anywhere except at zero. That is not an approximation that holds over the range shown. A fixed ratio is what always happens when two different constants are multiplied by one variable. Asked at what move size the two effects become equal, the honest answer is that no such size exists and the question has the wrong shape.

At what size of rupee move do the two effects become equal?

At none. Every reader forms the question as soon as two lines appear on one chart, so the flat answer earns its space. The question is looking for the wrong variable. A different branch, not a different move, is what would make the two effects equal.

Solve it and the size is exact. For a 5.0 per cent move to shift the bank translation reserve by the same Rs 4.03 crore that reaches profit at the invented group, the net investment would have to be Rs 80.64 crore rather than Rs 480 crore. Rs 80.64 crore is 16.8 per cent of the actual size of the branch investment. The bank would need a branch about a sixth of the one it has before the two effects were even comparable in magnitude. And even then they would still land in different places, because the size of an effect and the place it lands are two independent facts about an exposure.

Before the controls below are moved, the question the whole comparison turns on deserves a committed answer. Guessing and being wrong fixes this in the memory far better than reading it once more.

How many currency exposures does this case carry outside the trading book?

Three, and they belong to two institutions. A spreadsheet will add all three without being asked, and the total it produces describes nothing that exists.

The first is the invented bank net investment of Rs 480 crore in one overseas branch, a translation exposure, moving its translation reserve by Rs 24 crore on a 5.0 per cent move. The second is the invented group own net investment of Rs 288 crore in its overseas trading entity, also a translation exposure, moving the group translation reserve by Rs 14.4 crore on the same move. The third is the group Rs 201.6 crore payable, a transaction exposure, of which Rs 4.03 crore reaches profit. Two of the three are the same kind of exposure at different institutions and the third is a different kind of exposure at one of them, so no pair of the three can be added to anything meaningful.

Why is it wrong to rank currency exposures by size?

Because size and consequence are two different measurements, and in this case the arithmetic refuses to let them be confused. Ranked by size, the bank branch investment is first. Ranked by what reaches a profit and loss account, the bank branch investment is last, tied on zero with an exposure at another institution entirely. Same three objects, opposite order.

Is there a third type of foreign exchange exposure?

There is a third type. Economic exposureThe third type, being the effect of a currency on what a business can sell and at what price in future, named in this sequence and taught nowhere because this case carries no instance of it., also called operating exposure, is the effect a currency has on what a business will be able to sell in future and at what price. Economic exposure is neither a contracted amount with a date nor a balance already held. Economic exposure is the shape of a business changing because a currency moved and made a competitor cheaper or an input dearer.

Picture a street vendor outside a factory gate whose customers all work at that factory. Nothing the vendor has signed is denominated in another currency and nothing the vendor holds is either, so on the two definitions above there is no exposure at all. But if the currency moves far enough for the factory owner to lose orders to a cheaper foreign supplier, the vendor loses half a customer base without ever having touched a foreign currency. The vendor's lost customers are economic exposure, and the difficulty of putting a rupee figure on the loss is immediately apparent. Economic exposure has no instance and no figure in this case, so it is named and never worked. An invented number for it would have to reconcile against records that carry no such figure.

How does anybody actually use this distinction in a working week?

Four people use the distinction, and each uses it slightly differently. Comparing the four uses is the fastest way to check the distinction has been understood.

A lender writing a covenant uses it to decide which measure to write the covenant on. A covenant set on net worth catches every translation movement and is untouched by a transaction one until it settles. A covenant set on interest cover catches the transaction one the moment it hits the income statement and never sees the translation one at all. A covenant written without thinking about this is a test that fires on the currency effect nobody was worried about and stays quiet on the one that mattered.

An analyst reading a set of accounts uses it as a diagnostic. Equity fell, profit did not, and nothing was paid out: the first place to look is a translation reserve, and the follow-up question is what the entity holds abroad rather than what it bought or sold. Profit fell and equity fell by the same amount: that is a different story entirely and it is about cash. Knowing which of the two is in front of the reader settles what question comes next. Settling the next question is most of what reading accounts consists of.

A treasurer uses it to allocate attention and cover. Committed transaction exposures have dates, so they can be queued and covered against a policy floor. Treasury limit TL3 does exactly that at the invented group. Net investments have no dates, and this group and this bank have both chosen to leave them entirely uncovered. Leaving a net investment open is a decision somebody should be able to defend at a committee rather than a gap nobody noticed.

And a risk function uses it to decide what belongs in which report. A transaction exposure is an earnings question and a translation exposure is a capital and equity question, and the two reach different committees on different cycles. Putting them in one line item called foreign exchange exposure, with one total, is exactly the merge the third failure above warns about.
