Oil as a regional macro driver

Where the oil price enters a Gulf economy 

Oil reaches a household in the Gulf almost entirely through the state, and that single fact is what makes the barrel a macro variable in the region rather than a commodity like any other. Very little of the crude produced there is bought by the people who live above it. It is exported, and the receipts accrue first to a national oil company and, through royalties, taxes and dividends, to the government that owns it. The budget is where the oil price lands.

What the budget does next reaches everything else. In most economies of the Gulf Cooperation Council the government is the largest single source of domestic demand: it employs a substantial share of the national workforce, it awards the construction and infrastructure contracts that keep much of the private sector occupied, and it pays salaries that arrive as deposits in the local banking system. Those deposits are a large part of the funding base of the banks, and that funding base conditions the pace at which credit is extended to everyone else. The chain runs from an export price to government revenue, from revenue to spending and the timing of project awards, from awards to corporate revenue and employment, and from deposits to the cost and availability of credit.

That chain is fiscal, and it is slow. The module has so far taught a chain that is monetary and comparatively fast: inflation moves, an institution moves the price of short term money, and a currency reprices within seconds of the announcement. The oil chain has no such moment. It moves through budget cycles, project schedules and bank balance sheets, over quarters rather than hours. This is why the oil price can be simultaneously the most consequential number in the regional economy and not the number that moves a regional screen on any given morning.

There is no single oil price 

Crude is not one substance and it does not have one price. It varies in density and in sulphur content, it sits in different places, and a barrel is worth what a refinery configured for that grade, in that location, will pay for it. What the market quotes are benchmarks: reference grades, deliverable at a named point, against which the rest of the world's cargoes are priced as differentials. Brent refers to a set of North Sea grades and is the reference most used for internationally traded cargoes. West Texas Intermediate is the American benchmark, deliverable inland at Cushing in Oklahoma, so its differential to Brent can reflect the cost of moving crude out of the American midcontinent rather than anything about world demand. Gulf producers selling into Asia conventionally price against a Dubai and Oman based assessment instead, and publish official selling prices each month as a differential to it.

The consequence for a regional reader is worth stating plainly. An exporter's realised revenue per barrel is not the benchmark price on a screen. It is a benchmark plus or minus a grade and destination differential that the producer itself sets, on a published monthly schedule. The screen is a reasonable proxy for the direction of that revenue and a poor proxy for its level. A CFD written on oil references a benchmark futures contract rather than any physical cargo, and it inherits that contract's calendar, including the expiry that the foundations lesson on commodities described.

The price the budget was written on 

A government drawing most of its revenue from one export writes its budget on an assumed price for it. The revenue the budget needs from oil, divided by the volume the state expects to export, gives a price per barrel at which planned spending is exactly covered. That figure is the fiscal breakeven price, and it is the most useful single piece of arithmetic for reading what an oil move means to a producing state, because it converts a price into a fiscal position.

Two features of that arithmetic do most of the work. The first is that the breakeven price is a function of spending as much as of oil. A budget that expands raises the breakeven price with nothing whatever happening in the oil market, and a budget that is trimmed lowers it, which is why the same price is read as comfortable by one producing state and severe by another. The second is that the relationship is linear and symmetric: the same distance above and below the breakeven produces a surplus and a deficit of the same size.

What the price responds to 

On the supply side, the largest scheduled influence is the output policy of the exporting countries that coordinate production, announced at meetings whose dates are published well in advance. Alongside those decisions sit the unscheduled ones: outages from weather, conflict, sanctions, accidents and maintenance. How much any single outage matters depends on spare capacity, the volume that can be returned to the market quickly, which is why the same interruption is absorbed quietly in one period and not in another. Underneath both runs an investment cycle measured in years, since a barrel produced late this decade is a decision taken today.

On the demand side sit the growth and activity measures the module has already covered, industrial production and freight among them, together with seasonal patterns in refinery maintenance and in heating and driving. The dollar belongs on this list too, for a structural reason rather than an economic one: crude is quoted in dollars, so a move in the dollar changes the price of a barrel in every other currency with nothing having changed in the oil market at all.

Neither production nor consumption is observed in real time. Inventories are, at least for the largest consumer, and that is why they carry the weight they do. The change in stocks over a week is the nearest thing the market has to a running score of whether supply exceeded demand, and it is published on a fixed schedule while the two quantities it summarises are not.

The scheduled events 

Oil has its own calendar, and it sits beside rather than inside the macro calendar the module covered earlier. The recurring entries are these.

• Meetings of the coordinating producers, at which output policy is confirmed or changed. The date is known long in advance; the content is not, and the communication around it begins days before the meeting itself.
• The weekly American petroleum status report, published by the Energy Information Administration on Wednesday mornings, giving the change in crude and product stocks. An industry association publishes its own estimate the previous evening from a different and partial sample, which is why the two can disagree.
• Monthly reports from the producer group and from the International Energy Agency, each publishing its own estimate of supply, demand and the balance between them, and each revising earlier estimates as data arrives.
• Official selling prices, published monthly by Gulf producers as differentials to their reference assessment, which is where a producer's own view of demand in a destination market becomes visible.
• Expiry and roll dates of the benchmark futures contract, which belong to the contract rather than to the oil market, and which the instrument's specifications state.

The inventory report is also the clearest place in this lesson to see the mechanism the module taught two lessons ago, because the published number is compared with a surveyed expectation before it is compared with anything else. What is new in the release is the distance between the two, and that distance carries a sign.

What a calendar schedules is the arrival of information, not the direction of a price, and the reason a scheduled oil release belongs in a risk discussion is the one the module gave for a rate decision. Participants who would otherwise quote continuously widen or step back around a known publication time, so the interval between one tradeable price and the next can grow at precisely the moment the new information lands. A position held across a scheduled release is exposed to that gap, and an instruction to close at a specified level is executed at whatever price exists when it becomes executable, which in a gapping market is not the level named.

Oil and the currencies conventionally tied to it 

Commodity currency is the term for the currency of an economy whose export receipts are concentrated in raw materials. The Canadian dollar and the Norwegian krone are the two most often named in connection with crude, and the Mexican peso is sometimes included. The mechanism traders describe is a terms of trade argument: when the export price rises, the value of what the country sells rises against the value of what it buys, export receipts are larger, the fiscal position improves, and the domestic inflation and rate picture the currency's central bank faces changes with it. Foreign exchange traditions conventionally describe a rising crude price as associated with a firmer Canadian dollar, and therefore with a lower quote for the pair in which the dollar is the base currency.

The limits are large enough that it is reported here as a convention rather than as a relationship. It rests on correlation measured over a chosen window, and a correlation describes a past window rather than a property of the pair: the same two series over a different window have produced a weaker relationship, and at times an inverted one. It also ignores why the oil price moved, which changes what else is moving alongside it. A fall driven by weaker global demand is simultaneously a statement about global growth, and growth reaches the dollar and the exporters' currencies through channels that can work in opposite directions at once. The denomination compounds this, because crude is quoted in dollars and so is the pair, so a dollar move alone can push both series and produce a correlation with no causal content in it whatever. And the economies are not the caricature: Canada is diversified and its crude is heavy and sells at a differential rather than at the benchmark, while Norway channels a large part of its receipts into a sovereign fund that invests abroad, a structure deliberately built to weaken the very link being described.

Why a pegged currency does not absorb the shock 

For a floating exporter the exchange rate is the first absorber, and it works without anybody deciding anything. When the export price falls, demand for the currency falls with the receipts, the currency depreciates, and the effects run in the cushioning direction: the smaller foreign currency revenue converts into a less diminished local currency amount, imported goods become dearer, and domestic production competes more easily against them. None of that makes the country richer. It spreads the adjustment across the price level and the exchange rate rather than concentrating it in one place.

A pegged currency has that absorber removed by design, and it loses a second one at the same time. Holding a fixed rate while capital moves freely across the border requires the domestic policy rate to track the anchor currency's rate closely, because a meaningful gap between the two invites the arbitrage that would break the peg. The consequence is the one the earlier lesson on the regional institutions described: the domestic rate follows a decision taken for a different economy on a different cycle, and it is therefore not available as a response to an oil move either. The exchange rate cannot adjust and the policy rate is spoken for.

The adjustment has to appear somewhere, so it appears in the two places that remain. The first is fiscal: the size of spending, the phasing of project awards, the issue of sovereign debt, the drawdown or accumulation of financial assets. The second is bank liquidity, and this is the part that is easy to miss. Where government deposits are a large share of the banking system's funding, a fall in export receipts withdraws deposits from that system directly, and the local interbank benchmark rate can rise relative to the anchor rate with no policy decision having been taken by anybody. That is the same tightening of credit conditions a floating economy would have distributed into its currency, arriving instead through the funding market.

What follows is structural. In a pegged economy the spot rate is the least informative series in the chain, because holding it steady is the policy: it moves within a narrow band by construction, so a period of severe fiscal strain and a period of comfort look almost identical on that chart. The information sits in the interbank rate, in forward points and in sovereign borrowing, which are the instruments in which pressure on a fixed rate becomes visible. A peg does not remove an oil shock. It relocates it.

Where practitioners disagree 

Three arguments in this area are genuinely open. The first is how much weight a fiscal breakeven price deserves at all. One camp treats it as the single number that summarises a producing state's position. Another points out that a government with large accumulated assets, low debt and market access faces a financing question rather than a solvency one, so the breakeven describes the size of a gap and says nothing about how easily it is closed. Both are describing the same arithmetic and disagreeing about what the arithmetic is evidence of.

The second is whether the oil to currency relationships are structural or regime dependent. Sustained periods exist in which the conventional description held closely and others in which it did not hold at all, and no agreed method distinguishes the two in advance rather than afterwards. The third follows from it: the decomposition of an oil move into a supply cause and a demand cause, which is what would tell an observer which other markets to expect it to touch, is produced by models, published with a lag, and revised. In the hours during which a move is being explained on a screen, the decomposition being cited is an assertion rather than a measurement.
