Can a credit squeeze disrupt oil supplies?

Banking on Oil · Part 8 of 8

The UK prepared a £40 billion backstop for energy companies in autumn 2022. It received no applications and issued no guarantees. The Energy Markets Financing Scheme opened on 17 October to help firms in gas and electricity markets fund the cash demands arising from their hedges. It closed on 27 January 2023 without being used. The £40 billion ceiling was never a taxpayer bill of that size. At closure, the Bank of England noted that lower wholesale gas prices had eased some of the pressure on eligible firms. ^[1][2]

That outcome does not establish that the scheme was pointless. Announcing support and paying it out are different interventions; their effects cannot be read from the same number. But it provides a useful starting point for this final investigation. Funding pressure, a financial loss and an interrupted delivery describe different stages of a possible crisis.

A credit squeeze can disrupt supplies when cash is unavailable at the deadline and no other firm can take over the transaction in time. International financial institutions have identified this transmission mechanism. The public record does not, however, reveal a single oil price, debt figure or margin call that would automatically bring world trade to a halt. ^[17]

The cargo and the cash run on different clocks

The first instalment followed a cargo; the second traced the banks behind the trader. To understand how supplies might be interrupted, we now need to put three dates on the same calendar: payment to the supplier, collection from the customer and collateral calls on financial contracts.

Consider a trader holding oil and selling futures to protect against a fall in its price. If prices rise, the inventory may become more valuable while the futures position loses value. Whether these movements offset economically depends on the hedge and on being able to sell the actual cargo. Even an effective hedge does not guarantee matching cash receipts and payments. ^[3][4]

Variation margin settles changes in the financial contract’s value. Initial margin protects against potential losses during the time needed to close out a position after a default, and its amount may be revised. A firm may therefore need to fund both the price movement already recorded and a larger protective buffer. ^[3][4]

The central counterparty stands between buyers and sellers. A clearing intermediary acting for the trader can require additional collateral and must meet its own obligations even when the client is late. Holding a saleable cargo does not give the trader money that can necessarily be transferred straight away. ^[3]

A timing mismatch can be bridged. A customer default or fictitious inventory can cause an economic loss. An imperfect hedge leaves residual price risk. The nickel investigation demonstrated why the existence of the goods matters. There is another reason for caution with oil: price direction alone does not tell us which company needs cash. A rise affects different positions differently.

The same funding buys fewer barrels

Derivatives are not required for a funding squeeze. A trader already has to carry the cost of purchases until customers pay. Higher prices or slower collections can increase that requirement even if the volume of oil passing through the business is unchanged.

To isolate the mechanism, take a wholly hypothetical example, not an observed market price or a forecast. A company has a fixed US$80 million funding budget devoted entirely to the purchase cost of goods. It buys a steady volume every day and recovers precisely that cost after a set interval. Freight, interest, hedging collateral, profits and supplier credit are excluded.

In steady state, the daily volume that can be financed equals the funding budget divided by the oil price and then by the number of days for which the money is tied up. At US$80 a barrel and a 40-day funding interval, US$80 million supports 25,000 barrels a day.

At US$120, the same budget supports roughly 16,667 barrels a day. Extend the interval to 60 days as well, and capacity falls to approximately 11,111 barrels. The 55.6% reduction from the first case is the result of these assumptions, not an observed fall in deliveries.

The interval runs from paying for the goods to recovering their purchase cost. It may include transit, storage or the wait for an invoice to be paid. It is not simply the vessel’s sailing time. Nor does the calculation assume that every financed barrel is physically sitting in the trader’s tanks.

The model deliberately holds back the possible adjustments. The business might secure more funding, collect sooner, negotiate supplier credit or use its own resources. Its bank might recognise a higher inventory value. It could also demand more protection. Available funding is itself a variable in a crisis, not a universal constant. The chart shows why it must increase to sustain the same commercial flow when unit costs and the funding interval rise.

Who can take over the delivery?

Now suppose the trader reaches its funding limit. It can cut new purchases, sell down positions or seek a partner. The oil does not disappear. If a creditworthy rival can take over the cargo, obtain the necessary documents and arrange transport, the customer can still receive the product.

A disruption becomes possible when that replacement is unavailable or too slow. The obstacle might be credit, but it might also be unavailable storage, restricted terminal access or the time needed to transfer contracts. This is a conditional transmission scenario, not a single documented incident reconstructed from start to finish. In April 2022, the IMF warned that impaired derivatives markets could spill over into commodity availability. ^[17]

The practical question is who can supply the required product, at the agreed location and time, with funding already available. A long list of potential competitors is a poor answer if every candidate depends on the same credit channel or lacks access to the right infrastructure.

There are several outcomes between business as usual and a shortage. The customer may accept a delay, pay sooner or pay more. Another trader may expand its sales. Reduced activity at the original intermediary can therefore shift trade flows rather than cut consumption by the same amount. Without evidence on replacement transactions, converting a balance-sheet problem into “missing barrels” would amount to inventing the result.

This matters when interpreting headlines about a large trading group. Its annual volumes say little about the share of transactions that could be replaced promptly in a particular port. Substitutability has to be tested against a product, a location and a deadline, not assumed from either the size or the visibility of a company.

The financial system absorbed much of the 2022 shock

The Financial Stability Board’s February 2023 assessment does not support a simple collapse narrative. It found that the commodities-market ecosystem had largely absorbed the shock, with limited effects on the wider financial system. The severe disruption in London Metal Exchange nickel was a notable exception. That judgement about markets does not mean households, industrial users or energy suppliers escaped economic damage. ^[4]

Bank lending helped absorb the pressure, but with an important qualification. In July 2022, the Bank of England judged that banks had enough capital to meet the sector’s financing needs. It also made clear that actual lending would depend on banks’ risk decisions. A well-capitalised lender is not committed to financing every borrower. ^[5]

Some companies also sought bilateral derivatives requiring less immediate collateral. By November 2022, the ECB had found signs of this adjustment but limited evidence of a wholesale migration. Its warning was about the other side of the arrangement: easing the customer’s cash requirement could increase the counterparty’s exposure. ^[6]

There is no need to assume unlawful evasion to understand that transfer. A bank can take on a funding requirement that its client no longer meets directly, charge for the service and carry the additional exposure. That may be a workable solution. Its capacity still depends on the provider. Under a common market shock, the availability of the alternative matters as much as its contractual design.

Reducing hedges also requires careful interpretation. It can lower an immediate collateral requirement while leaving the business more exposed to prices. An improvement in today’s cash position, on its own, does not establish that the company has become safer overall.

Uniper had an economic loss to absorb

Uniper illustrates a different causal chain. When contracted Russian gas stopped arriving, the company had to purchase more expensive replacement volumes to meet its commitments. In its 2022 results, it reported approximately €13.2 billion of realised additional replacement-gas costs. That item was neither temporary margin posted nor the whole IFRS net loss. ^[7]

In December 2022, the European Commission authorised a recapitalisation intended to restore the company’s financial position and avert serious disruption in Germany’s gas market, subject to conditions. Uniper subsequently reported receiving approximately €13.5 billion through capital increases during financial year 2022. The amount authorised and the amount actually provided are different measures. ^[8][9]

Here, a physical supply failure first caused a loss, which then threatened the capacity to keep delivering. Describing the problem as waiting for an offsetting future gain would miss the point. The company needed to absorb the cost of a substitution that had become much more expensive.

The story also continued after the rescue. On 13 March 2025, Uniper announced that it had settled an approximately €2.6 billion repayment obligation to the German state two days earlier. Subtracting that payment from the capital injection would not establish the intervention’s final net cost: the value of the state’s investment and its other cash flows would also have to be accounted for. ^[9]

The unused British guarantee scheme and the German recapitalisation thus represent different instruments addressing different problems. Comparing them helps diagnose the underlying difficulty. It does not produce a meaningful ranking of taxpayer exposure.

Standby credit has a maturity too

On 10 March 2026, Trafigura announced a US$3 billion contingent facility alongside its ordinary refinancing. The initial tenor was six months, with two three-month extension options. Twelve participating banks were named. The disclosure documents a contractual source of funding intended for periods of heightened volatility; it is not a statement that the company had received US$3 billion in cash. ^[10]

The facility matters, and so does its duration. To assess the protection at a particular date, one would need the drawdown conditions, the remaining availability and confirmation of any extensions. The release does not provide all that information. Our research through 8 September 2026 did not find public confirmation that the extensions had been exercised; that is not evidence that they had not been exercised.

An extension option must remain an option in the analysis. Treating it as twelve months of firm funding from the outset would overstate the protection disclosed. Equally, treating the existence of a maturity date as a solvency warning would go beyond the evidence.

The useful question is not just how much a company can borrow, but when and on what terms. Two identical headline amounts can serve very different purposes when one is immediately transferable and the other depends on a decision or a procedure.

More detailed safeguards, with a defined scope

On 10 December 2024, the FSB published eight recommendations on liquidity preparedness for margin calls, including contingency funding plans, stress tests and usable liquidity resources. Their scope requires care: non-financial commodity traders are not directly covered. The FSB says that they and their counterparties could benefit from adopting the recommendations as sound practices. ^[11][12]

That is not a finding that commodity traders are generally unregulated. The Dutch central bank, for example, explains that specified non-financial counterparties can be subject to clearing obligations under EMIR, the European derivatives regulation, for defined contract classes and under particular conditions. A market-regulation regime and a liquidity-preparedness framework do not necessarily cover the same ground. ^[16]

On 15 January 2025, international banking, payments and securities standard setters published margin-transparency proposals and practices for improving margin flows. The operational aim is straightforward: give participants a better understanding of possible calls and reduce friction between collecting and distributing the money. ^[13][14]

Work continued in 2026. A CPMI-IOSCO consultation published on 6 May, with responses due by 30 June, proposed changes to CCP guidance and public quantitative disclosures. As of 8 September, our review had not identified a subsequent final text for that consultation. Presenting the whole package as fully implemented everywhere would be premature. ^[15]

The objective cannot simply be to make collateral smaller. Too little protection leaves more unpaid losses with counterparties; a difficult-to-anticipate increase can strain cash resources. Greater predictability and stronger funding arrangements address different sides of the same problem. The two objectives need to be assessed together.

Testing the whole delivery chain

The policy work can be extended into the physical trade through three questions. These are analytical tests, not an official score assigned to the groups in this series.

Will the money arrive before the deadline? A useful test puts payments and receipts on one calendar, in the required currencies. Cash must be distinguished from assets that need to be sold and facilities that need to be drawn. A large liquidity total may conceal a mobilisation delay. Operational readiness and resources available under stress are central to the FSB’s recommendations. ^[11]

Will the alternatives remain available together? Several contracts can still leave a business dependent on providers exposed to the same shock. The test should examine conditions and concentrations without assuming that every credit line will disappear. It follows the Bank of England’s distinction between the ability and the willingness to lend. ^[5]

Who takes over if the intermediary withdraws? A replacement needs purchase funding, the product, the necessary rights and timely logistical access. Finding a new owner, lender or transporter need not take the same amount of time. This is where balance-sheet analysis meets the infrastructure examined earlier in the series.

The public documents reviewed do not match every group’s physical commitments, hedges and available funding at every relevant deadline. The ECB had already warned that missing physical-position information limits the interpretation of derivatives exposures. A ranking of traders by imminent supply-disruption risk would therefore exceed the available information. ^[6]

This series has examined Chad’s oil-backed debt, the making of a Platts benchmark, Vitol’s physical infrastructure and bribery in the Trafigura–Petrobras trade. The intermediary’s contribution is as tangible as its dependence on credit: buying a product, carrying risk and organising delivery before recovering the money spent.

A breaking point arises when an unavoidable payment meets unavailable funding and a replacement that cannot arrive in time. The 2022 shock demonstrated that several buffers can work; Uniper showed why some losses demand much more than a short-term cash bridge. Understanding these mechanisms helps explain a crisis without predicting the next interruption to supplies.
