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 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 submit examines how non-financial corporations (henceforth ‘commodity merchants’) reacted to this liquidity stress, and the way their reactions impacted the functioning of commodity derivatives markets. Commodity spinoff markets are necessary for the actual financial system and the current occasions underscored the necessity to higher perceive the interdependencies between margin and counterparty threat administration practices.

Margin necessities and liquidity pressures

Value 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 occasions the pre-invasion worth in March 2022, solely to later attain 11 occasions the pre-invasion worth 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 unstable, and are nonetheless far above ranges usually seen over the 2010s.

On account 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 should be met with money, whereas preliminary margin calls might 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 charge – which is a base degree of required preliminary margin for a given contract – for the front-end (shortest out there maturity) futures contract for key commodities. On high of this, some CCP clearing members utilized margin add-ons or multipliers when sending the margin calls to their purchasers to mirror 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 worth 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 vitality corporations or commodity merchants, who would have been required to pay margin through the commodities stresses of 2022. In precept they may promote property to satisfy margin calls for. Nonetheless, sale of the corresponding bodily product can take anyplace 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 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 current liquidity stress 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 adjustments 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 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 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 the intention to entry quick liquidity. The liquidation of secure 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 could draw throughout stress. Because of this, in regular occasions, 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 lowered their hedging actions altogether. This will likely 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 worth shocks and amplify impacts to the actual 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 occasions of stress. Preliminary margin necessities on non-centrally cleared transactions (akin to these calculated by way of eg the ISDA Normal Preliminary Margin Mannequin) are typically much less reactive to will increase in market volatility and due to this fact less expensive for buyers. For centrally cleared markets, a discount in exercise was seen in out there information: 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 Alternate 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 needs to be famous that that is solely a partial lower of information relative to the European Gasoline (Netherlands TTF), and that different jurisdictions could have noticed totally different patterns. One cause 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 result 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 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, momentary modification of collateral necessities, and so forth). That is constant too with the statement 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 search out further liquid assets, typically at simply the occasions when it’s most tough 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 idea, variations within the reactivity of margins imply that liquidity may shift from centrally to non-centrally cleared OTC spinoff markets in occasions of stress. Nonetheless, different features of margin fashions, and variations in margin practices, together with waivers and multipliers, or eligible collateral could have performed an even bigger function in incentivising behavioural shifts. A evaluate 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 beneficial growing 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 in regards to the totally different liquidity wants and methods of economic and non-financial firms. The latter don’t maintain liquidity buffers in the identical means the previous usually do but are topic to related liquidity calls for throughout occasions 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 actual financial system.

In response to the intense liquidity pressures vitality corporations face on account 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 predominant dynamics outlined above by enabling the availability of short-term monetary assist to vitality corporations of excellent credit score high quality for the aim of assembly collateral necessities that come up as a result of hedging exercise.
