The dollar inside Europe’s energy bill

A ten-million-dollar purchase would have cost €8.604 million at the reference exchange rate on 4 September 2026. At the 12 October reference rate, it would have required €8.944 million. The invoice and the goods are unchanged: roughly €339,000 extra, in a conversion without hedging or bank charges. Between those dates, the euro fell from $1.1622 to $1.1181 in the European Central Bank’s reference series. ²

On 9 October, Reuters reported that the euro was heading for a fifth successive weekly decline, while discussing concerns over French public finances. ¹ For an importer, the two markets meet on one invoice. More expensive energy requires more dollars; a weaker European currency makes each dollar harder to buy.

The continent’s exposure is substantial. Eurostat puts the EU’s net energy import dependency at 57% in 2024. This physical ratio measures net imports relative to energy needs. It covers the European Union, rather than just the euro area, and says nothing about the currency or hedging arrangements of individual contracts. ⁶

That distinction runs through this investigation. An economic risk can be visible on trading screens before it reaches an invoice. It can surface at the next contract renewal, be absorbed in margins, or require funding well before the goods are delivered.

One barrel, two price movements

The basic calculation is worth making explicit. When one euro buys $1.20, a barrel priced at $120 costs €100. If the euro buys only $1.10, the same barrel costs €109.09. Divide the dollar price by the number of dollars one euro buys. A currency’s depreciation and the corresponding rise in the domestic cost of foreign currency have different percentage changes because the denominators differ.

To examine the recent episode, we pair the European Brent spot price published by the US Energy Information Administration with the ECB’s daily reference exchange rate. Between 1 September and 6 October 2026, the dollar price rose from $96.02 to $125.44 a barrel, or 30.6%. Converted using each date’s exchange rate, it rose from €82.85 to €111.31, or 34.4%. ^{2 3}

The chart retains the intervening observations: prices moved unevenly, with declines as well as increases. The oil series reviewed was released on 7 October and ends on 6 October. FRED reproduces the same final observation; it republishes EIA data rather than independently confirming the price. The available exchange-rate series extends to 12 October. The matched comparison therefore stops on 6 October, without carrying the oil price forward. ^{3 4}

These are spot-price observations, referring to immediate delivery of a benchmark crude. They differ from futures tied to a later delivery period, and from the negotiated price of a particular cargo. The EIA defines the price basis and identifies Refinitiv as the underlying data supplier. The ECB reference rate is informational, not a bank’s executable conversion quote. ^{5 14}

To separate the effects, first hold the exchange rate at its 1 September level. The oil quoted on 6 October would then cost €108.23. The dollar oil-price move adds €25.38 to the initial euro price; switching to the 6 October exchange rate adds another €3.08. Together they account for the €28.47 increase per barrel.

The decomposition deliberately applies oil first, then currency. Reversing that order changes how their interaction is allocated, while leaving the total unchanged. This is an accounting attribution that helps explain an invoice. It does not identify the causes of market movements: the oil shock may itself influence the euro, expected growth and interest-rate expectations.

The contract determines which dollar matters

There are several steps between a benchmark barrel and the energy a company actually uses. A refinery buys a particular crude grade; a road haulier buys diesel; an airline buys jet fuel. Each price also reflects processing, delivery location, transport and availability. Crude oil feeds several fuels, each with its own market. ⁵

A Brent hedge can therefore leave the spread between crude and the purchased fuel exposed. This is basis risk: the protected benchmark and the actual expense move differently. Hedging a hundred units of crude does not automatically fix the delivered cost of a hundred units of a refined product. The ECB’s work on energy derivatives also documents differences between products and delivery locations. ⁹

Contract currency adds another layer. European TTF natural gas is quoted in euros per megawatt-hour, according to ICE’s specifications. Applying an additional EUR/USD conversion to a price increase already expressed in euros would double-count the currency step. Competition with alternative supplies can influence TTF prices; the euro quotation has nevertheless already determined the currency used in the calculation. ⁷

A company consequently needs to reconstruct its own pricing formula: energy benchmark, local premium or spread, fixing period and payment currency. A euro invoice may contain a dollar-linked price adjustment. Conversely, fixing a dollar commodity price in advance still leaves currency exposure until payment unless a further protection is arranged.

This is the level at which “hedged energy” becomes a useful description. A reported hedge percentage summarises a volume and a period. It needs to be read alongside the protected price, the currency and the expenses to which it applies.

A hedge can leave the extra dollars exposed

A currency hedge applies to a specified amount and settlement date.

Consider a hypothetical company buying 100,000 barrels. It budgets at $100 a barrel and $1.20 per euro, giving a cost of €8.333 million. At delivery, assume a price of $125 and an exchange rate of $1.10 per euro. Without protection, the bill reaches €11.364 million, up 36.4%.

This is an illustrative case. The prices, volume, hedge rates and simultaneous settlement are assumptions. Charges, initial collateral, taxes and basis differences are excluded to isolate the two risks.

If the company fixes oil at $100 a barrel, its economic dollar cost stays at $10 million. Buying those dollars at the new exchange rate still costs €9.091 million. The commodity hedge does its job, while the domestic-currency bill rises by 9.1%.

Now suppose it locks in $10 million at $1.20 per euro, leaving oil unhedged. The currency contract covers the amount originally budgeted. The final purchase, however, costs $12.5 million. Another $2.5 million must be obtained at the new exchange rate. Total cost becomes €10.606 million, combining the contracted dollars with the additional spot purchase.

The distinction matters: a currency hedge sized against an initial budget can leave the entire increase in the dollar invoice unprotected. Describing the original ten million as fully hedged would be accurate. Inferring that the complete future bill was protected would overstate what the contract covers.

With oil fixed at $100 and the matching $10 million secured at $1.20 per euro, the model returns to €8.333 million. Amounts, maturities and benchmarks match. In a real transaction, forward exchange terms also reflect financing conditions; a budget rate is not interchangeable with a hedge rate. The illustration assumes no actual bank offer at the stated terms.

Changes in consumption can create further mismatches. A manufacturer cutting output may have secured too much currency or fuel. One increasing production needs additional cover. Treasury management therefore includes regularly matching financial contracts to the evolving physical business.

Protection comes with an expiry date

Our investigation of Asia’s dollar-hedging machinery also follows the renewal of currency protection.

A hedge can carry a company through several expensive months with comparatively stable costs. As it expires, the company must buy at prevailing prices or arrange a new contract. If the shock persists, expenditure gradually moves towards the new market level. A temporarily contained bill reveals the timing of protection as much as the eventual exposure.

Air France-KLM’s disclosures show why the year matters. In its 30 July 2026 results, the group reported hedging 67% of expected fuel consumption for 2026 and 40% for 2027. Those are fuel positions disclosed at that date, not an October snapshot of all the group’s currency risks. ¹⁰

Renewal can also occur in a cheaper market. A company may then carry expensive legacy protection while screen prices fall. The symmetry is useful: depending on the instrument, securing a budget means giving up some future favourable price moves. An assessment should compare physical spending and hedge results across the same exposure.

Inventory has its own timetable. Purchasing, delivery, processing and sale enter cash flow and financial accounts at different moments. A daily Brent quotation and a quarterly result can describe separate stages of one process. Fixing periods and volumes must be identified before a gain or loss can reasonably be attributed to a hedging strategy.

A protected price can still require cash before delivery

Our analysis of margin calls likewise separates the economic loss from cash required at a contractual deadline.

Hedging can reduce economic risk while creating liquidity needs. In cleared contracts, margin payments settle changes in value and protect counterparties. The ECB’s analysis of the 2022 crisis describes how these requirements could lead energy companies to seek bank funding. That episode illustrates a mechanism; it does not quantify margin calls in October 2026. ⁹

The direction of the position is crucial. An oil buyer protected by a long position normally gains on that hedge when the relevant benchmark rises. It may instead have to provide cash when the price falls, before benefiting from the cheaper physical purchase. ¹⁶

In a second simulation, independent of currency, the company fixes 100,000 barrels at $100 through a futures contract. Twenty days later, that same contract trades at $80. Cumulative variation margin represents a $2 million cash outflow. The company needs liquidity while delivery is still ahead.

At day sixty, assume settlement at $125. The recovery from $80 produces a $4.5 million variation-margin inflow. Physical oil costs $12.5 million. Across the full period, the net hedge gain is $2.5 million, bringing the economic cost back to $10 million.

The dollar budget holds in this idealised model. Yet two million dollars had to be advanced along the way. Initial deposits, charges and financing interest are excluded; they would create additional demands.

Without a hedge, a larger physical invoice can also raise the funding required to hold stock before customers pay. Price protection, available cash and access to the goods need to be examined together. A financial contract transports no oil and cannot by itself remedy a delivery delay.

The increase has to find a margin to squeeze

Our investigation of emergency oil reserves and pump-price transmission traces the passage from a benchmark to retail fuel prices.

Return to the euro bill. A third simulation considers a company with €20 million of sales, €12 million of other costs and €5 million of energy expense. Its simplified operating surplus is €3 million, or 15% of sales. The example excludes tax, financing, depreciation and volume effects.

Apply only to energy the same hypothetical shock used above, 36.4% after rounding. Energy now costs €6.818 million. With sales prices and volumes unchanged, operating surplus falls to €1.182 million, a 60.6% contraction. Energy’s weight in the cost base explains the amplified effect on the result.

If the company recovers 60% of the added cost from customers, sales rise to €21.091 million and surplus to €2.273 million. Customers bear an extra €1.091 million; the company retains a €727,000 reduction in surplus. This allocation is an assumption, not an estimate of what customers would actually accept.

Even recovering the entire additional expense leaves a distinction. Surplus returns to €3 million, but against sales of €21.818 million. The percentage margin remains lower: 13.75%, compared with 15% initially. Preserving an absolute amount of profit and preserving a profit margin are different objectives.

Beyond this company, selling prices depend on competition, demand and when contracts can be revised. Banco de España’s research into exchange-rate pass-through emphasises that variation: import content, invoicing currency, value chains and market power influence transmission. It recommends accounting for the kind of shock instead of relying on a single coefficient. ⁸

Pump prices add refined-product costs, distribution and taxes. The European Commission publishes fuel prices with and without tax, alongside VAT and excise information. ¹² A fixed levy per unit dilutes a percentage shock to the total price; a proportional tax moves with its taxable base. That arithmetic is no substitute for each country’s applicable tax rules.

Moving from there to overall inflation requires product weights and an account of price changes over time. A 34.4% rise in converted crude is not a forecast of 34.4% European inflation. The evidence here measures the first stage. It cannot quantify all the subsequent ones.

Some European businesses gain from the dollar

A weaker currency increases the euro value of dollar receipts. The relevant exposure, however, is after dollar purchases and other payments. A hypothetical business receiving $10 million and spending $6 million has a net $4 million exposure. With activity unchanged, a move from $1.20 to $1.10 per euro raises its euro equivalent from €3.333 million to €3.636 million.

Hedges can defer that benefit just as they defer an importer’s losses. In its 28 July 2026 results, Safran said its 2026 net exposure was fully hedged, targeting $1.12 per euro against an annual net exposure assumption of $16 billion. The company disclosure illustrates how the economic conversion rate can differ from the rate visible on a screen. ¹¹

For a net energy-importing economy, the wider issue is national purchasing power. If imports become more expensive relative to exports, more output or income must be exchanged for the same foreign goods. This is a deterioration in the terms of trade, the ratio of export to import prices. France’s Treasury studied in 2022 how that income loss was allocated between businesses, households and the public budget. ¹³

An exporter gaining from currency, a company absorbing costs, a hedged supplier and an exposed household can all coexist. Private foreign-exchange gains do not automatically compensate every energy importer. Conversely, a national bill calculated with fixed quantities would overstate actual spending if imports fell. Lower volumes can reflect efficiency gains or lower production, with very different economic implications.

Monetary policy starts beyond the conversion

A weaker euro increases imported price pressure. More costly energy can simultaneously squeeze spending on other goods and discourage investment. The central bank needs to assess these effects over time, alongside price expectations and business responses.

In an interview conducted on 1 October and published on 6 October, Philip Lane said energy prices exceeded the ECB baseline assumptions, while very strong second-round effects had not yet appeared. He also highlighted the restraint that higher long-term yields can impose on activity and inflation. ¹⁵

The distinction is practical. Higher fuel costs paid today are a direct effect. A transport company subsequently revising its charges passes part of the shock onwards. If wages, margins and other prices adjust persistently in response, the pressure becomes longer-lasting. The speed and scale of those stages help determine the monetary response.

This investigation establishes an increase in converted crude costs and reconstructs ways to carry the risk. It does not reconstruct all European hedges or their renewal calendar. Nor does it isolate the separate contributions of oil and French fiscal tensions to the euro’s movement.

The useful variables for reading upcoming industrial results will be the share of purchases left open, the dollars actually secured, protection expiry dates and the ability to revise prices. Over a longer horizon, reducing energy required per unit of output directly reduces the quantity needing finance and cover. The exchange rate explains part of the bill; contracts and physical energy use determine where and when that bill lands.
