The Russian invasion of Ukraine in February 2022 and subsequent sanctions led to unprecedented will increase in key commodity costs. Whereas costs briefly abated in late spring and early summer time, these surged once more over late July and August, with EU and UK fuel costs reaching new peaks on 26 August. These strikes created a sudden and vital demand for liquidity from market members with derivatives positions. This put up examines how non-financial companies (henceforth ‘commodity merchants’) reacted to this liquidity strain, and the way their reactions impacted the functioning of commodity derivatives markets. Commodity spinoff markets are necessary for the true financial system and the latest occasions underscored the necessity to higher perceive the interdependencies between margin and counterparty danger administration practices.

Margin necessities and liquidity pressures

Worth strikes on some key futures contracts following the invasion had been extraordinarily sharp however had been surpassed by strikes in late August. Dutch TTF pure fuel, for instance, peaked at eight instances the pre-invasion value in March 2022, solely to later attain 11 instances the pre-invasion value in late August. As of early November 2022, pure fuel costs in Europe have considerably retraced and are extra consistent with pre-invasion ranges, however stay risky, and are nonetheless far above ranges usually seen over the 2010s.

Because of this elevated volatility and sharp adjustments in costs, central counterparties (CCPs) referred to as for extra preliminary and variation margin to cowl brief derivatives positions in commodities. Variation margin calls have to be met with money, whereas preliminary margin calls could be met with money or a spread of eligible securities (normally authorities bonds). Notably, preliminary margin charges on pure fuel in ICE Clear Europe elevated sixfold from January to April 2022; they’ve remained elevated since. Chart 1 reveals the margin fee – which is a base stage of required preliminary margin for a given contract – for the front-end (shortest accessible maturity) futures contract for key commodities. On prime of this, some CCP clearing members utilized margin add-ons or multipliers when sending the margin calls to their shoppers to replicate their credit score dangers.

When costs are rising, variation margin is paid by those that have brief positions; in commodity derivatives, non-financial establishments akin to commodity merchants, producers, and end-suppliers usually maintain structural brief positions as they search to guard the portfolio towards value drops throughout future gross sales. These brief positions are offset by commodity customers (eg airways) and monetary gamers, like sellers and asset managers. As such, it’s predominantly non-financial corporates, akin to power companies or commodity merchants, who would have been required to pay margin through the commodities stresses of 2022. In precept they might promote property to satisfy margin calls for. Nonetheless, sale of the corresponding bodily product can take wherever between 20 and 90 days, relying on the commodity in query. This implies there’s a timing mismatch between the margin calls they’re required to pay on their spinoff positions, and the time required to promote their precise bodily merchandise. The assorted money move wants of non-financial commodity merchants are illustrated in Determine 1.

This timing mismatch between realised money flows has been on the crux of latest liquidity strain on commodity companies, however it isn’t a brand new drawback. For instance, in 1993, German industrial conglomerate Metallgesellschaft required a liquidity injection from a gaggle of banks after sudden adjustments within the form of the oil curve left it dealing with massive hedge accounting losses and margin claims.

Liquidity administration and market incentives

A spike in volatility like that noticed in March–April 2022 interacted with these inherent options of merchants’ enterprise fashions to supply adjustments in market behaviours. Whereas a few of these had been anticipated, some weren’t, and lift necessary questions for policymakers.

First, variations in liquidity administration between non-financial and monetary companies strained the functioning of bodily commodities markets. Evaluating non-bank monetary establishments and commodity merchants is instructive. Through the March 2020 ‘sprint for money’, non-bank monetary establishments offered authorities bonds or used them as collateral for borrowing in repo markets, so as to entry quick liquidity. The liquidation of protected property, coupled with limits in vendor intermediation capability, led to exacerbated volatility and dysfunction in core monetary markets.

In distinction, non-financials akin to commodity merchants maintain little to no investments in securities (akin to authorities bonds) on which they could draw throughout stress. Because of this, in regular instances, commodity merchants depend on credit score strains (akin to revolving credit score amenities) with banks to satisfy their liquidity wants. Following the steep and sudden rise in margin calls, commodity merchants have primarily sought to extend borrowing capability of their credit score strains. This labored to a sure extent; nevertheless, as banks’ danger urge for food in commodities markets tightened, some merchants sought credit score elsewhere (akin to from personal fairness) or diminished their hedging actions altogether. This may occasionally go away them unable to seize the advantages of hedging ahead future manufacturing and susceptible to sharp swings within the costs. Or result in a discount of bodily provide ought to an incapability to hedge lead members to exit the market. Each improve pass-through of value shocks and amplify impacts to the true financial system.

Second, market liquidity and buying and selling volumes modified in surprising methods because the shock developed. In concept, variations within the reactivity of margins fashions to volatility will increase ought to incentivise a shift from centrally to non-centrally cleared over-the-counter (OTC) spinoff markets in instances of stress. Preliminary margin necessities on non-centrally cleared transactions (akin to these calculated through eg the ISDA Commonplace Preliminary Margin Mannequin) are usually much less reactive to will increase in market volatility and subsequently less expensive for traders. For centrally cleared markets, a discount in exercise was seen in accessible knowledge: Chart 2 reveals open curiosity in TTF one-month futures falling greater than 40% from pre-invasion ranges. Vital drops are additionally seen in different markets akin to Brent oil and aluminium.

Open curiosity belongs to contracts traded on the Shanghai Futures Trade for aluminium, Chicago Board of Commerce for wheat, ICE Futures Europe for Brent crude oil and EDX-ICE Endex for TTF fuel.

Nonetheless, the non-centrally cleared OTC exercise in UK markets additionally declined sharply. Chart 3 reveals a 50% decline in OTC buying and selling exercise between June 2021 and June 2022. It ought to be famous that that is solely a partial lower of information relative to the European Gasoline (Netherlands TTF), and that different jurisdictions might have noticed totally different patterns. One motive for the decline is the tightening of danger urge for food: on the first peak of the disaster in March, there was much less willingness to enter into OTC trades with commodity merchants because of counterparty credit score danger issues, notably much less well-rated ones. Additional complicating the incentives at play is the truth that a number of elements apart from margin width, affect the selection of which the spinoff markets have to make use of for his or her trades (eg portfolio netting, non permanent modification of collateral necessities, and so on). That is constant too with the commentary that, for a given market construction, reactions of market members and banks can amplify volatility shock.

Coverage implications

Along with implications for markets and liquidity administration, this episode has underscored three necessary classes for future coverage work.

First, on condition that preliminary margin is designed to cowl potential future losses within the occasion of a counterparty default, it’s pure for ranges to extend as volatility will increase. Nonetheless, these sudden adjustments may cause liquidity stress whereby events posting margin have to seek out further liquid sources, usually at simply the instances when it’s most troublesome to take action.

Second, adjustments in investor behaviour and buying and selling exercise have additional underscored structural points in commodity derivatives markets and margining practices. In concept, variations within the reactivity of margins imply that liquidity may shift from centrally to non-centrally cleared OTC spinoff markets in instances of stress. Nonetheless, different facets of margin fashions, and variations in margin practices, together with waivers and multipliers, or eligible collateral might have performed an even bigger function in incentivising behavioural shifts. A assessment of margining practices by the Basel Committee on Banking Supervision, the Committee on Funds and Market Infrastructures and the Worldwide Group of Securities Commissions checked out margin practices through the Covid ‘sprint for money’ in March and April 2020. The report advisable rising transparency of margin practices in centrally cleared markets and evaluating the responsiveness of CCPs’ preliminary margin fashions to totally different market eventualities.

Third, the episode has raised questions concerning the totally different liquidity wants and methods of monetary and non-financial companies. The latter don’t maintain liquidity buffers in the identical approach the previous usually do but are topic to related liquidity calls for throughout instances of stress through margin calls on derivatives used for hedging. This episode ought to immediate extra cautious considered non-financial companies’ use of derivatives, their liquidity resilience, and their interconnection with the true financial system.

In response to the intense liquidity pressures power corporations face because of steep margin calls, the Financial institution and HM Treasury launched the Power Markets Financing Scheme on 17 October 2022. It seeks to quell one of many major dynamics outlined above by enabling the supply of short-term monetary help to power companies of fine credit score high quality for the aim of assembly collateral necessities that come up because of hedging exercise.
