Exposure: What Is Actually at Risk Before Any Hedge

An exposure is the part of what a party holds, owes or has agreed whose value moves with a price that party does not control. Naming one takes four facts: the item, the quantity in units, the direction that hurts, and the date it stops mattering. An exposure exists whether or not anybody has written it down, and it exists before any contract.

Prices move whether anybody is watching them or not. A party is tied to some of those prices by things it has already done: a purchase made, a debt taken on, a sale promised for a later date. The tie is the whole subject of this guide. The hedging work that follows is about changing the tie, and none of it can be read sensibly until the tie itself has been described.

Describing the tie comes first, and this guide stops there. A description writes down what is at risk, in a form a stranger could check. Choosing, sizing and entering are covered separately.

What is an exposure, in plain terms?

An exposureThe part of what a party holds, owes or has agreed whose value moves with a price it does not control. has two halves, and the definition is worth reading slowly because both halves have to be there. There has to be an attachment, meaning something the party has already bought, already owes or has already agreed to, and there has to be a price the party does not set. Take away the first half and there is nothing for a price to reach. Take away the second half and the price is not a risk, it is a decision. A shopkeeper who fixes the price on a shelf is not exposed to that price. The shopkeeper is exposed to the price paid for the stock on the shelf, and somebody else set that price.

Notice the words the definition leaves out. The definition mentions no record, no system, no report and no person noticing. An exposure is not created by noticing it and is not removed by ignoring it, so a party that has never described a single one of its exposures has every one of them all the same. Arriving unasked is the difference between an exposure and almost everything else in a set of accounts. A provision has to be made. A valuation has to be performed. An exposure simply arrives, at the moment the purchase is made or the agreement is signed, and it waits.

Here is the everyday version, and it is worth keeping beside the finance one all the way down. A household runs on one salary and has signed an agreement to pay a fixed sum every month. The sum going out is fixed by the agreement. The sum coming in depends on decisions made by somebody else in an office the household has no say in. The household is exposed to those decisions, and it was exposed on the day the agreement was signed, not on the day somebody at the kitchen table first said the word out loud. Nobody had to describe it for it to be true.

The finance version worked here runs on one invented thing called the reference asset, the name used for it throughout. The reference asset has a spot price of Rs 2,000.00/-, and it pays nothing at all while it is held. A payout during the holding period would change every figure below. The party with something at risk is called the holder. The part at risk is the exposure, and the particular thing that exposure attaches to is the hedged item.

Which four facts have to be nameable before an exposure has been described?

Saying that something is at risk is not a description of an exposure. The phrase is a mood. A description has four facts in it, and each of the four answers a question that a contract, a report or a conversation will otherwise answer by guessing.

1. The itemThe specific thing whose price reaches this party. Not the sector, not the theme, not the general area. Here the item is one invented reference asset, and the reason the item has to be specific is that a contract exists on some things and not on others, and nothing about that is decidable while the item is a category.
2. The quantity, in units of the thingUnits, not money. Money moves while the units sit still, so a quantity written in rupees quietly changes every time the price changes, and a description that changes on its own is not a description. Twenty units stays twenty units through any price at all.
3. The direction that hurtsWhich way the price would have to go for this party to be worse off. The direction belongs to the position and not to the item. The same thing therefore produces opposite answers for a party holding it and a party that has agreed to buy it.
4. The date it stops matteringAlso called the horizonThe date on which the exposure stops mattering to this party, usually because the thing is sold, bought or delivered on that date., and it is a fact about this party's own affairs rather than about the market. Nobody outside the party can supply the date. Whether a move is a problem depends entirely on whether it happens before or after the party has finished with the item, so a description without the date cannot be checked.

Here is the standard for whether the four are done: a stranger reading them should be able to say what would go wrong and roughly when. If a reader can get to the end of a description and still not know which direction is the bad one, or still not know whether this matters next month or in four years, the description has failed, however precise the numbers in it look. How these four are set out in order on a sheet, and what else goes on that sheet beside them, is covered separately.

Where do exposures come from inside one party?

From three places rather than one, and a party that looks in only the first place will find roughly a third of what it has. The three are worth learning as a set. The third one looks like the first and behaves exactly like it, and the second one looks like the third and behaves like its opposite.

The first is something already bought and held. A unit is in the party's possession today, paid for, sitting there. A fall in the price hurts. Nothing further has to happen for this to be true. The source appears on the list of what the party has, so everybody finds it.

The second is something already agreed to be paid for. A purchase has been committed to, at a price that is not yet fixed, and the agreement is a commitmentSomething already agreed to be bought or sold at a price that has not yet been fixed. The agreement binds; the price does not exist yet.. A rise in the price makes the thing the party has promised to buy cost more, so a rise hurts. Nothing is in the party's possession. The exposure is real all the same.

The third is something already agreed to be sold, again at a price not yet fixed, and here a fall hurts, exactly as it does for the thing already held. What matters is which way the party is leaning, not whether the thing is physically in its possession. The lean rule is the whole of the block, and it is the reason a list of holdings is not a list of exposures. A party that lists only what it has in its possession has listed one of three sources and called the result complete.

The everyday version of the third source is a street vendor who has taken an order for next week's function at a price to be settled on the day of delivery. Nothing has been cooked. Nothing is in the vendor's possession. A fall in the price on the day makes the order worth less, and the vendor is already committed to filling it, so the vendor is leaning exactly the way somebody with a full storeroom leans. Anybody who walked into that storeroom to count what was at risk would count nothing and be wrong.

Can two exposures inside the same party cancel each other before any contract?

Two exposures inside one party can cancel, and this is the least expected part of the subject, so it gets the worked instance and the simulation both. A party holds twenty units of the reference asset at the spot price of Rs 2,000.00/-. Twenty units at Rs 2,000.00/- comes to Rs 40,000.00/-, the gross exposureThe total before offsetting positions inside the same party have been subtracted from it.. The gross figure is what a list of holdings produces, and for most parties it is the only figure anybody ever writes down.

Now add the second list. The same party has already agreed to sell five of those units at a price fixed today. The five committed units have their price settled by an agreement, so they no longer move with anything. Five units of the holding and five units of the commitment point in opposite directions and cancel each other exactly. Fifteen units at Rs 2,000.00/- is Rs 30,000.00/- of net exposure, against Rs 40,000.00/- of gross exposure on the whole holding, and reaching it cost nothing at all. No contract was written. Nothing was bought. Nothing was posted anywhere. Two things that were already inside the party met each other on paper.

Fifteen units rather than twenty is what the net exposureWhat is left once offsetting positions inside the same party have been subtracted. It is the figure a description of what is at risk should carry. means, and it is the cheapest change available anywhere in this material. Every other way of changing an exposure that appears on this platform costs something: a price given up, an obligation taken on, cash to be found on a bad day. Netting costs a subtraction.

Now the trap, and it is the failure this guide ends on. A party that writes a contract against the gross figure of twenty units has covered five units twice. The five committed units were already settled by the agreement, so whatever is written against them stands against nothing. A position with nothing behind it is a position taken on its own, and that is covered separately. The gross figure describes a lean the party does not actually have, so the right count to describe, and therefore the right count to work from, is the net one.

One more caution before the numbers get comfortable. Netting is not an errand anybody has to go on, and a party that finds no offsets has found the truth as surely as one that finds ten. The subtraction is a statement about which number is true. The net figure is the description; the gross figure is an ingredient of the description. A party that reports the gross figure has not been conservative, it has been inaccurate, and being inaccurate in the cautious direction still leads to covering something that was never there.

Two figures in this material print the same and mean something different, so they are worth separating here rather than leaving a reader to trip over the pair later. The Rs 30,000.00/- worked here is exposure with nothing whatever written against it, reached by subtraction inside one party's own records. The Rs 30,000.00/- that appears under hedge sizing is exposure that does have a contract written against it, reached by writing one. Fifteen units at Rs 2,000.00/- is Rs 30,000.00/- by either route, so the two figures agree by arithmetic accident while describing two different states of affairs. Anybody carrying the number without the sentence attached to it will eventually put it in the wrong column.

Which of the three kinds of exposure can these figures actually work?

Three named parts follow, and they describe three different kinds of item: an amount fixed in another currency, a quantity of a physical thing, and a priced financial thing. All three are described in exactly the same way, with the same four facts, and only the third can be worked in figures here. The reason is not a judgement about which one matters, but a plain shortage of material.

The shortage, stated once and then repeated inside each part where it bites, is this. The working record behind this material carries one invented reference asset at a spot price of Rs 2,000.00/- and a financing rate of 6.50 per cent a year. The record holds no second currency and no rate between two currencies, no commodity, no quantity of one and no price for one, and no second price series of any kind. So the currency part and the commodity part are taught as the shape they share with everything else here, and neither of them invents a rate, a pair, a grade or a price in order to look as complete as the third.

Working either of the first two in numbers takes three things, and they are the same three both times. Two separately priced things. A price between them, or for each of them, on every date that matters to the party. And a record of both that somebody can check. None of the three exists here, and a worked example built without them would be fiction dressed as arithmetic.

How can a contract on a pair of currencies change what is at risk?

How Currency Derivatives Can Change Foreign-Exchange Exposure

Start with the shape. The shape is the part that transfers. A party has an amount fixed in another currency, to be received or to be paid on a later date. The amount in that other currency is known exactly. The amount in this party's own currency is not known at all, and will not be known until the day it moves. An amount fixed in another currency, unknown in this one, is a foreign-exchange exposureAn amount fixed in another currency whose value in this party's own currency is not yet known., and it fills in the four facts the same way everything else here does.

A rate is always between two things, so the item is the pair of currencies rather than one of them. The quantity is the amount in the other currency, and it is written in that currency for exactly the reason quantities are written in units everywhere else here: it stays still while the value in this party's own currency moves. The direction that hurts follows from whether the amount is coming in or going out, so a party expecting to receive is hurt by one direction and a party expecting to pay is hurt by the other, in the lean rule from the three sources over again. The date is the day the amount actually moves.

A contract on that pair changes one thing, said in one sentence: the party stops holding an unknown amount in its own currency and starts holding an agreed one. Replacing an unknown amount with an agreed one is the whole of the change, and the third part below works that same change in figures on a different kind of item. An obligation arrives with it, namely to complete the exchange on the date, whether or not the underlying amount turns up on time, and that obligation is a new fact about the party rather than a modification of the old one.

Now the absence, and it belongs inside this part rather than in a footnote. The working record behind this material contains no second currency and no rate between two of them. There is one invented reference asset with one price on it. So this part carries no arithmetic, and no rate is manufactured in order to produce some. The same structure is worked further down on an item these figures do support, and the structure is genuinely the same: an amount that moves with a price nobody here controls, and a contract referencing that same price standing against it.

The everyday version, and it needs no rate either. A student has been told that a fee due next year is a fixed number in another country's money. The number in that money is certain. The number in the money the household actually earns is not, and it will not be certain until the day the fee is paid. Nothing about the student's position requires anybody to know the rate. The position requires only that the rate is not set by the household.

The routing matters more than usual here. Whether an exposure in another currency may be covered by a contract at all, and by whom, and on what conditions, is set by the Reserve Bank of India at rbi.org.in, and what a privately agreed arrangement has to be reported as, to whom and by when, is set there too. Both of those move, and both are read at that source.

How can a contract on a physical thing change what is at risk?

How Commodity Derivatives Can Change Commodity-Price Exposure

Again the shape first. A party will buy or sell a stated quantity of a physical thing on a later date, at a price that is not yet fixed. A quantity to be traded later at a price not yet fixed is a commodity-price exposureA quantity of a physical thing to be bought or sold later at a price that has not yet been fixed., and the four facts fill in as follows. The item is that thing, in a stated quality and at a stated place. The quantity is in whatever units the thing is measured in. The direction that hurts follows from whether the party is buying or selling. The date is the day it changes hands.

A contract on that thing changes the familiar sentence with a different noun in it: the price for the quantity covered stops being open and becomes agreed. The party takes on the obligation that comes with the contract and the amount that has to be funded behind it, exactly as in the third part below.

But one thing here is genuinely different from the currency part, and it is the reason these two are not the same part with two names. A contract on a physical thing is written on a stated grade and placeThe stated quality and the stated location a physical contract is written on. Both are part of the contract's own description of what it references.. The contract does not reference the thing in general, only that quality of it, in that location. So a party holding a different quality of the same thing, in a different location, is covered by something that is not quite what it has, and the difference between the two is left over. How much is left over when the two sides do not line up is covered separately. The mismatch is physical rather than arithmetic.

The everyday version is a wedding caterer who has taken an order for a function four months away, at a price to be settled nearer the date, and who will have to buy the ingredients in a particular quality from a particular market. A contract written on a different quality, or on stock sitting in another city, changes something, but it does not change exactly the thing the caterer is worried about. Anybody who has ever collected the wrong grade of anything for a function knows in their body why this matters, without any arithmetic at all.

The absence again, and it is stated here rather than left to the reader to infer. The working record contains no commodity, no quantity of one and no price for one. So this part carries the shape and no arithmetic, and it invents neither a thing, nor a grade, nor a place, nor a price in order to produce some. The figure below draws the fields that would have to be filled in and deliberately leaves every one of them empty. The fields are the teaching, and the entries are not in these figures.

The routing here belongs to a different authority from the currency part. Which contracts on physical things may be entered into, by whom and on what conditions is set by the Securities and Exchange Board of India (SEBI) at sebi.gov.in, as is the size of one contract, the units it stands on, and who may carry a position at all. Every one of those moves, and every one is read at that source.

What do the four facts read like once a contract is written against the unit?

How Hedging Can Change a Financial Exposure

The financial part is the one that carries the arithmetic, and it carries it because a financial exposureAn amount whose value moves with the price of a financial thing, or with a financing rate. is the only one of the three these figures support. Take one unit of the fifteen the party is actually exposed on. The four facts read: the item is the reference asset, the quantity is one unit, a fall hurts, and the date is whenever the unit is sold.

Now write a contract against it on the short position. The contract binds the holder to sell one unit on the later date at a price agreed today. The contract price is not chosen and not negotiated. Arithmetic produces it. Financing costs 6.50 per cent a year and the reference asset pays nothing at all while it is held, so nothing comes in to set against the cost of carrying it. Rs 2,000.00/- multiplied by 0.065 is Rs 130.00/-, and Rs 2,000.00/- plus Rs 130.00/- is Rs 2,130.00/-. The Rs 2,130.00/- is what the financing rate produces rather than what anybody expects the price to be, and the Rs 130.00/- inside it is the carry. Why that is so, and why anybody offering to sell forward for less would be handing out money, is covered separately and used here as finished work.

Now read the four facts again, one line at a time. The change is the whole point of the part.

The fifth line is the one worth staring at. Writing the contract brings an amount that has to be funded from somewhere, and on these figures it is the initial margin of 8.0 per cent on Rs 2,000.00/-, or Rs 160.00/- on one unit. The 8.0 per cent used here is a teaching figure, not a requirement, and not a figure anybody may carry away. Real requirements are set by clearing corporations under SEBI's framework at sebi.gov.in, they differ by contract and by day, and they move. The invented figure is here only so the fifth line has something in it.

Where does the Rs 160.00/- come from? Not from the unit. The unit is the thing being covered, and selling it to fund the margin against it would undo the arrangement in the act of paying for it. So the fifth line is a claim on something else the party has, and it is the reason a description of an exposure gains a line rather than losing one when a contract is written against it. The exposure did not leave the sheet. The exposure changed what it was written against, and the sheet got longer.

At which moment does the covered direction actually read as neither?

At one moment, and the table above says which: the final date, the day the contract settles. The date has to be said out loud every time a line like that is written. The line is not true on the other days, and a reader who carries it away undated will be surprised by the first mid life reading they ever take.

Take the fall the record uses. The price of the reference asset moves from Rs 2,000.00/- to Rs 1,920.00/-, a gap of Rs 80.00/- struck on a base of Rs 2,000.00/-. On the final date, the unit held and the unit sold forward are prices for the same day, so they cancel rupee for rupee and the covered direction genuinely reads as neither. With a full year still to run, they do not cancel rupee for rupee, and the reason is that the carry applies to the new price as well as to the old one. The contract price for that same later date becomes Rs 1,920.00/- multiplied by 1.065, which is Rs 2,044.80/-, and against the Rs 2,130.00/- written into the holder's own contract that is a gap of Rs 85.20/-. A gap of Rs 80.00/- in the price today has become a gap of Rs 85.20/- in the price for the later date, and Rs 5.20/- is left standing.

So the offset is over complete before the end and exact only at it. How much of a move an offset actually catches is covered separately. The discipline is this. Every reading names the moment it is taken at, and the same two positions produce different answers on different days without either answer being wrong.

What is an exposure not?

Two confusions are common enough to be worth naming separately, and both of them lead a party to write down a figure that describes something other than its position.

An exposure is not a loss. An exposure is what moves, not what has moved. A party with a very large exposure and a price that has sat still has lost nothing at all, and a party with a small exposure and a price that has collapsed has lost something real. The two are different measurements of different things, and one of them is about the future while the other is about the past. Nothing in the description has happened yet, so none of it is a loss.

An exposure is not a notionalA figure a calculation is applied to. It is a multiplier, and it need not move anywhere at all. either, and this is the expensive one. A notional is a figure a calculation is applied to. The notional is a multiplier, and a multiplier may sit in an agreement for years without moving anywhere. An exposure is the amount actually standing behind a party's position, and that amount is what a price move would affect.

Here is the size of the gap, using an arrangement settled earlier in this subject area and borrowed here only for its two figures. A notional of Rs 1,000 crore multiplied by a difference of 1.20 percentage points a year produces Rs 12.00 crore of net difference over the first period. The Rs 1,000 crore never changes hands. Rs 12.00 crore against Rs 1,000 crore is 1.2 per cent of it, so the multiplier is more than eighty times the amount that actually moves. Reporting the multiplier where the exposure belongs describes an arrangement many times larger than the one actually held.

Why is that expensive rather than merely untidy? Because a party that overstates its own exposure will cover something that was never there, and covering something that was never there is a position taken on its own, with everything that comes with it. Overstating in the cautious direction produces the same accidental position that understating produces, only in the other direction. So every quantity throughout this material says whether it is notional or exposure, in the same sentence as the number.

What would have to be known before anybody could say what to do about this?

A reader who has just written down an exposure will feel that something now has to be done about it, and that feeling is exactly where care is needed. An exposure is not a problem awaiting a solution. An exposure is a fact about a position. A party may carry it deliberately, may reduce it inside its own records the way the fourth section did, or may write a contract against it, and this platform does not say which of the three anybody should do.

Describing an exposure is not the first step of a process that ends in a trade. Describing an exposure is work with its own value, and it is finished when the description is accurate, whatever anybody does next. The party that describes twenty units correctly as fifteen has already changed its position for the better in the only sense that can be vouched for here: it now knows what it has.

Answering whether to act on an exposure would take several further facts. The party's purpose, and what it exists to do. Its capacity to fund a bad day without selling the very thing it was trying to protect. How long the exposure runs and whether it renews. Whether a contract on the item exists at all, and on what dates. And what SEBI at sebi.gov.in sets down before a position is treated as a hedge rather than as a position taken on its own, read at that source.

Notice what is not on that list. How well anything worked last time, an event these figures do not contain. Whether covering is the careful or the responsible thing to do, a description of a feeling rather than of an arrangement, with the word carrying the feeling free of charge. Understanding what an exposure is has never been a reason to change one.

The reference asset and the holder are invented.
