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 season, these surged once more over late July and August, with EU and UK gasoline costs reaching new peaks on 26 August. These strikes created a sudden and vital demand for liquidity from market contributors with derivatives positions. This submit examines how non-financial corporations (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 threat administration practices.
Margin necessities and liquidity pressures
Worth strikes on some key futures contracts following the invasion have been extraordinarily sharp however have been surpassed by strikes in late August. Dutch TTF pure gasoline, 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 gasoline costs in Europe have considerably retraced and are extra in keeping with pre-invasion ranges, however stay unstable, and are nonetheless far above ranges sometimes seen over the 2010s.
Because of this elevated volatility and sharp modifications in costs, central counterparties (CCPs) known as for extra preliminary and variation margin to cowl quick derivatives positions in commodities. Variation margin calls should 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 gasoline in ICE Clear Europe elevated sixfold from January to April 2022; they’ve remained elevated since. Chart 1 exhibits the margin charge – which is a base degree of required preliminary margin for a given contract – for the front-end (shortest obtainable 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 quick positions; in commodity derivatives, non-financial establishments akin to commodity merchants, producers, and end-suppliers sometimes maintain structural quick positions as they search to guard the portfolio towards value drops throughout future gross sales. These quick 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 vitality corporations or commodity merchants, who would have been required to pay margin throughout 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 varied money stream 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 corporations, 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 modifications within the form of the oil curve left it going through 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 modifications in market behaviours. Whereas a few of these have been anticipated, some weren’t, and lift necessary questions for policymakers.
First, variations in liquidity administration between non-financial and monetary firms strained the functioning of bodily commodities markets. Evaluating non-bank monetary establishments and commodity merchants is instructive. Throughout the March 2020 ‘sprint for money’, non-bank monetary establishments offered authorities bonds or used them as collateral for borrowing in repo markets, with a view to entry quick liquidity. The liquidation of protected property, coupled with limits in seller 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 may draw throughout stress. For that reason, in regular instances, commodity merchants depend on credit score traces (akin to revolving credit score services) 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 traces. This labored to a sure extent; nevertheless, as banks’ threat urge for food in commodities markets tightened, some merchants sought credit score elsewhere (akin to from non-public fairness) or diminished their hedging actions altogether. This will likely depart 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 lack of ability to hedge lead contributors 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 advanced. In idea, 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 by way of eg the ISDA Customary Preliminary Margin Mannequin) are typically much less reactive to will increase in market volatility and subsequently less expensive for buyers. For centrally cleared markets, a discount in exercise was seen in obtainable knowledge: Chart 2 exhibits 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 gasoline. Vertical dashed line marks the beginning of the Russian invasion of Ukraine on the 24 February 2022.

Nonetheless, the non-centrally cleared OTC exercise in UK markets additionally declined sharply. Chart 3 exhibits 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 minimize of knowledge relative to the European Gasoline (Netherlands TTF), and that different jurisdictions could have noticed completely different patterns. One purpose for the decline is the tightening of threat 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 as a consequence of counterparty credit score threat issues, significantly much less well-rated ones. Additional complicating the incentives at play is the truth that a number of components aside from margin width, affect the selection of which the spinoff markets have to make use of for his or her trades (eg portfolio netting, short-term modification of collateral necessities, and so on). That is constant too with the commentary that, for a given market construction, reactions of market contributors 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 modifications could cause liquidity stress whereby events posting margin have to search out extra liquid assets, usually at simply the instances when it’s most tough to take action.
Second, modifications in investor behaviour and buying and selling exercise have additional underscored structural points in commodity derivatives markets and margining practices. In idea, 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 elements of margin fashions, and variations in margin practices, together with waivers and multipliers, or eligible collateral could have performed a much bigger position in incentivising behavioural shifts. A overview 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 throughout the Covid ‘sprint for money’ in March and April 2020. The report really useful growing transparency of margin practices in centrally cleared markets and evaluating the responsiveness of CCPs’ preliminary margin fashions to completely different market eventualities.
Third, the episode has raised questions concerning the completely different liquidity wants and techniques of monetary and non-financial firms. The latter don’t maintain liquidity buffers in the identical manner the previous sometimes do but are topic to comparable liquidity calls for throughout instances of stress by way of margin calls on derivatives used for hedging. This episode ought to immediate extra cautious thought of non-financial corporations’ use of derivatives, their liquidity resilience, and their interconnection with the true financial system.
In response to the acute liquidity pressures vitality firms face because of steep margin calls, the Financial institution and HM Treasury launched the Vitality Markets Financing Scheme on 17 October 2022. It seeks to quell one of many primary dynamics outlined above by enabling the availability of short-term monetary assist to vitality corporations of fine credit score high quality for the aim of assembly collateral necessities that come up as a consequence of hedging exercise.
