Gold: Commodity, Currency Hedge and Household Asset

Gold is three separate things at the same time, and most arguments about it come from mixing them. Gold is a commodity, with a supply that answers slowly and a demand that answers quickly. Gold is also priced in another currency, so a rupee holder's move contains a currency component that has nothing to do with the metal. And it is a household asset held for reasons that are not returns.

Everything below sits on one number already established. In the invented Republic of Sankhya the exchange rateThe price of one currency written in another. Here it says how many Sankhya rupees one Marut unit costs, and it is set in a market of its own. is 80.00 Sankhya rupees to one Marut unit, and the world price of gold is quoted in Marut units rather than in rupees. A world price quoted in Marut units is what turns gold into three things instead of one. A household in Sankhya that holds a unit of gold is holding a metal whose price is settled somewhere else, and paying for it in a currency whose value against that somewhere else keeps moving.

What kind of thing is gold, economically?

Three different claims get made about gold, usually inside the same conversation, and they are not versions of one another. The separation does more work than any evidence either side can produce, so it comes before any examination of the three.

The first claim is that gold is a commodity. Gold is dug out of the ground, refined, weighed and sold by weight. There is a quantity available this year and a quantity wanted this year, and the price settles where those two meet, exactly as it does for a metal nobody writes newspaper articles about.

The second claim is that gold is a currency exposure. The world price of gold is quoted in a currency that is not the rupee. So a household in Sankhya holding a unit of gold holds two things at once: a quantity of metal, and a claim whose rupee value depends on what a Marut unit costs in rupees this morning. Central banks hold gold as a reserve assetSomething a central bank holds so that it can meet obligations to the outside world. Foreign currency, deposits with other central banks and gold all sit in that category. for something close to this reason, and that is a different sentence from anything about jewellery.

The third claim is that gold is a household asset. A household in Sankhya holds gold for four reasons. Gold can be split, a neighbour recognises it without a document, it can be kept in the house without an institution standing behind it, and it does work inside obligations that are not financial at all.

Almost every argument about gold is two people defending different ones of those three claims, and once they are separated most of the argument disappears. One person is saying the metal has a supply and a demand the way copper does. The second is saying the rupee number moves on causes that never touch the metal at all. The third is saying that the reason it sits in a cupboard has nothing to do with either. All three are right. The three claims answer different questions, and each is taken one at a time from here.

Does being a metal let gold escape the cycle other commodities have?

No, and the reason is worth stating rather than assuming. Gold is mined. A mine takes years to find, permit, sink and bring into production, and once it is running it does not stop quickly either. So the quantity supplied this year was very largely settled by decisions taken several years ago, and no price move this week can reach back and change them.

In the Sankhya illustration the two speeds are written down. Demand answers a price move inside one period. New supply answers in four, and the gap between those two speeds is the whole of the commodity cycleThe repeating pattern of shortage, high price, delayed new production and then surplus that shows up in any good whose supply takes years to build.: a shortage lifts the price now, the answer to the shortage arrives four periods later, and by then demand has already stepped back from the higher price. The overshoot is the lag. The overshoot is nobody's mistake, and the mechanics of it are set out under the commodity cycle itself.

Gold does have one feature that changes the size of the effect without changing its shape. Almost every gram ever mined still exists, sitting in vaults, in cupboards and around wrists, so the stock already above ground is very large next to the quantity mined in any one year. The large above-ground stock makes new mine supply a smaller lever on the price than it is for a metal that gets burned up in use. The stock does not make the lag disappear. The stock moves where the answering supply comes from, out of existing holdings rather than out of the ground, and existing holdings answer on a schedule of their own.

Nothing about being a metal, and nothing about being the metal people write about, exempts gold from a supply that answers slowly. Different commodities differ in how they are quoted, not in whether the lag applies. For crude oil the world settles on named reference grades so that a contract can point at one. Brent and West Texas Intermediate are two such benchmarkAn agreed reference grade or index that contracts point at, so that two parties who never meet can still mean the same thing by a price. grades, and gold carries quoting conventions of its own. The conventions differ. The arithmetic of a slow supply does not.

How much of a rupee move in gold is the metal and how much is the currency?

The split between the metal and the currency is settled by arithmetic rather than by judgement.

A unit of gold in the Sankhya illustration has a world price of 2,000 Marut units. The rate is 80.00 Sankhya rupees to one Marut unit. Multiply the two: 2,000 times 80.00 is Rs 1,60,000/-. Rs 1,60,000/- is what one unit of gold costs a household in Sankhya, and it is the only number that household ever sees written down.

Now move one thing, and one thing only. The rate goes from 80.00 to 84.00. The world price is left exactly where it was, at 2,000 Marut units. Multiply again: 2,000 times 84.00 is Rs 1,68,000/-. The rupee price of a unit of gold has risen by Rs 8,000/-. On Rs 1,60,000/- that is a rise of 5.00 per cent.

Nothing happened to the metal. No mine closed, no vault emptied, no jeweller ran short. The world price that the whole world reads is the same 2,000 Marut units it was the day before. A household in Sankhya valuing its holding this morning at Rs 1,68,000/- instead of Rs 1,60,000/- is looking at a currency move wearing a metal's clothes, and there is nothing in the rupee figure that says so.

The rupee number is the only number most people ever meet, so the split is worth sitting with. A price quoted in rupees is two things multiplied together, and only one of them is about gold. Pulled apart, the sentence changes completely. The rupee price rose 5.00 per cent. The world price rose 0.00 per cent. The rate rose 5.00 per cent. The world price and the rate together are the whole event. The rupee figure on its own is a story about metal that never happened. The rate itself, and why it moved, is settled under the exchange rate.

Why is gold called a currency hedge, and what does that claim actually cover?

Stated precisely, the claim is this: because gold is priced in a currency that is not the rupee, a fall in the rupee lifts the rupee price of gold without anything happening to gold. The worked case above shows exactly that happening. The loose version of the sentence quietly hands the metal a property it does not have, so the mechanism is worth naming exactly.

The hedge is arithmetic about where a thing is priced, not a property of the metal. Test it by running something else through the identical multiplication. In the same illustration a barrel of crude oil costs 50 Marut units. At a rate of 80.00 that is Rs 4,000/-. Move the rate to 84.00 and leave the barrel price where it is: 50 times 84.00 is Rs 4,200/-, and Rs 4,200/- on Rs 4,000/- works out at 5.00 per cent, the same percentage gold produced, on a substance that could hardly be less like a precious metal.

Anything priced in Marut units does this. A machine invoiced in Marut units does it. A subscription billed in Marut units does it. A debt repayable in Marut units does it too, in the direction that hurts rather than helps. The arithmetic is the same one seen from the other side of the transaction. The property belongs to the pricing currency, and not to the thing being priced.

So what survives of the claim? Something real but much narrower than it sounds. Gold does carry a currency exposure, a household can hold it in small amounts without an account anywhere, and it does not depend on a counterparty staying solvent for that exposure to keep working. Divisibility, portability and the absence of a counterparty are genuine differences from a deposit or an invoice written in Marut units. The idea that does not survive is that the metal itself possesses a defence against a falling rupee. The defence sits in the denominator, and gold is simply one of very many things standing on top of it.

What do the three cases look like side by side?

So far only one thing has moved at a time. Put all three cases next to each other, starting from the same place every time: a world price of 2,000 Marut units at a rate of 80.00, or Rs 1,60,000/-.

Case one is the metal alone. The world price rises 5.00 per cent to 2,100 Marut units and the rate stays at 80.00. The rupee price is 2,100 times 80.00, or Rs 1,68,000/-. The rupee move is 5.00 per cent, and every point of it is metal.

Case two is the currency alone. The world price stays at 2,000 Marut units and the rate moves to 84.00. The rupee price is 2,000 times 84.00, or Rs 1,68,000/-. The rupee move is 5.00 per cent, and not one point of it is metal.

Something has already happened before the third case arrives. Case one and case two land on the identical rupee number, Rs 1,68,000/-, and they are completely different events. Nothing in the rupee price distinguishes them, and nobody reading only the rupee price could say which one occurred. One rupee number standing for two different events is the whole reason the split is worth doing.

Case three is both together. The world price rises to 2,100 Marut units and the rate moves to 84.00. The rupee price is 2,100 multiplied by 84.00, or Rs 1,76,400/-. Set beside the starting Rs 1,60,000/-, the holding has gained Rs 16,400/-, and that works out at 10.25 per cent.

Two moves multiply, they do not add, so five and five make 10.25 and not 10.00. The extra quarter point is not a rounding artefact and it never cancels. The extra quarter point is the metal's 5.00 per cent rise being paid for in a currency that itself became 5.00 per cent dearer, worth Rs 400/- on this holding. Written out in rupees: Rs 8,000/- of metal, plus Rs 8,000/- of currency, plus Rs 400/- where the two meet, is Rs 16,400/-. The same multiplication runs through the Sankhya oil bill on a much larger move, where a 20.00 per cent price rise and a 5.00 per cent currency rise give 26.00 per cent rather than 25.00, and the gap widens as either move grows.

Why do households hold gold when it earns nothing?

A holding that pays no coupon, no rent and no dividend looks like a mistake to anyone who assumed a return was the point. A return usually was not the point. Four reasons come up again and again in households across South Asia, and not one of them is about a return.

Gold can be divided. A wedding set breaks into bangles and a bangle sells on its own. Very few household holdings can be reduced to exactly the amount needed and no more. A field cannot be sold by the corner. A house cannot be sold by the room. Half a bangle is a perfectly ordinary transaction.

Gold is recognised. A shopkeeper three streets away will take it without reading a document, without a system being online, and without knowing anything at all about the person holding it. A hallmarkA mark stamped on an item to certify the purity of the metal in it, applied under a scheme run by a standards body rather than by the seller. turns the purity claim into something checkable rather than a matter of trust. Recognisability without paperwork is a genuine property, and remarkably few things have it.

Gold can be held without an institution. No branch has to stay open, no custodyThe business of holding something on someone else's behalf and keeping the record of who holds what. A depository or a bank vault does it for a fee. arrangement has to hold, and no account can be frozen while a dispute is sorted out. Holding without an institution matters most exactly where institutions reach least, and that is a large part of why the pattern is strongest in rural households and weakest where a branch is on the corner.

Gold does work that is not financial. Gold moves at marriages, at births and at deaths. Gold settles obligations between relatives and neighbours that no bank product addresses, and the obligation is discharged in metal because metal is what the obligation was always written in. A rupee transfer of the identical value would not do the same job, and everyone involved knows it.

The four reasons are real rather than errors, and a reader who calls the holding irrational has quietly assumed that a return was the objective. Once the four reasons are on the table, the question stops being why anyone holds a thing that earns nothing. The question becomes what the holding is for, and it has an answer.

What does holding something that earns nothing cost?

Three things, and they are separable, so separate them the same way the rupee price was separated.

The first is opportunity costWhat is given up by choosing this use of the money rather than the next best one. The cost never appears on a receipt, and has to be constructed on purpose.: what the same money would have earned somewhere else across the same stretch of time. Nothing leaves anybody's pocket, so in most illustrations the forgone return is the largest of the three and the least visible.

The second is storage and safekeeping. A locker carries a charge. Insurance carries a premium. Keeping it in the house carries no invoice and a different kind of cost. The cost is real even though nobody bills for it.

The third is the difference between the price at which a household can buy and the price at which the same household can sell. Every market quotes two prices, a bid and offerThe two prices quoted at once in any market: the lower one at which a dealer will buy and the higher one at which the same dealer will sell., and the gap between them is paid whether or not the price of the metal moves at all. On physical gold there is usually a making charge on top, paid once at purchase and recovered never.

Invented figures on the Rs 1,60,000/- holding for one year show the shape rather than the size. Suppose the same money would have earned 6.00 per cent elsewhere, or Rs 9,600/-. Suppose safekeeping costs Rs 1,200/- for the year. Suppose the round trip between the buying and the selling quote is 2.00 per cent of the amount, or Rs 3,200/-. The three costs add to Rs 14,000/-, and Rs 14,000/- on Rs 1,60,000/- is 8.75 per cent.

A thing that earns nothing is not a thing that costs nothing. That sentence is arithmetic and not a verdict. A different assumed alternative return changes the total with it. A different safekeeping arrangement changes it again. Every one of those three inputs is chosen by the reader rather than supplied by the metal. The hedge argument above has exactly that shape: the number belongs to the surrounding arrangement, not to the gold. The three costs can be counted, and the counting comes before any decision about whether they are worth paying.

Who actually uses this split, and what do they do with it?

A lender against gold uses it before anything else. A loan secured on gold is a loan secured on a rupee value that has a currency component inside it, so the lender has to settle which reference price it values against, how often it revalues, and how much margin it keeps between the loan and the metal. The margin is doing two jobs at once: absorbing a metal move and absorbing a currency move. A lender who sized it for one has sized it for half the problem, and will find that out on the day both move together and multiply.

An equity analyst covering a jewellery retailer uses it to read inventory. A retailer holding metal reports a gain when the rupee price rises, and that gain looks identical whether it came from the world price or from the rate. A rate move flatters the value of inventory without a single extra customer walking through the door, so an analyst who wants to know whether the business actually sold more jewellery has to strip the rate move out of the reported number first.

A household uses it in the plainest way of all. The rupee value of what is in the cupboard went up. The question worth asking first is whether the world price moved. If the world price did not move, then measured in Marut units, the quantity the holding would fetch abroad, nothing has changed at all. The number on the valuation slip moved and the metal did not.

In all three cases the work is the same single subtraction, and in none of the three does it end with a decision about the metal. The lender ends with a margin. The analyst ends with a cleaner revenue line. The household ends with an accurate description of what happened to it. The next step depends on circumstances particular to that lender, that analyst and that household.

Which questions does the arithmetic leave open?

Gold attracts more advice than any other household holding, so the limit of the arithmetic is worth stating plainly.

Three claims about gold separate cleanly, and one of them computes all the way through. A 5.00 per cent rupee move can be entirely metal, entirely currency, or a mixture, and a mixture multiplies rather than adds. Holding gold carries three costs, and an illustrative figure sits against each.

Whether to hold gold, how much of it and when are three separate questions, and the arithmetic above reaches none of them. Whether a price is high, low or fair is a fourth. None of the four has a general answer, because the answer changes with the holder rather than with the metal. A rupee price splits into a metal part and a currency part for everybody, and what to do about either part comes out differently for every household.

The arithmetic is not what makes those questions hard, since the arithmetic is done above. The answer depends instead on what a particular household or institution already holds, what it already owes, which currency its obligations are written in, how soon it needs the money, and what it would otherwise do with it. None of that is the same for two households.

The separation gives a reader the ability to ask the question properly. A reader who can say which of the three claims they are making, and who can subtract the currency out of a rupee price before reading it, is asking something that has an answer. A reader who cannot is asking about a number with two different things multiplied inside it, and no amount of confidence about gold will repair that.
