Position limits in commodity markets: how they work

Position limits in commodity markets cap the number of futures contracts, or equivalent swaps, that a single trader may hold. They exist to reduce the risk that a large speculative position will distort prices or make it hard for others to trade. Limits apply to speculators. Commercial firms that use derivatives to offset real business risk can generally obtain exemptions for bona fide hedging.

Both the federal government and the exchanges set limits, and the two layers do not always match. This guide explains the logic, the main categories and the exemptions, and it describes how limits relate to a hedging strategy.

In brief

• The Commodity Exchange Act, as amended by Dodd-Frank, requires limits intended to prevent excessive speculation from causing sudden or unreasonable price swings.
• The CFTC’s 2020 final rule set federal limits for 25 physically settled core referenced futures contracts, plus linked contracts and economically equivalent swaps.
• Federal spot-month limits are set at or below 25 percent of estimated deliverable supply.
• Federal non-spot-month limits apply only to nine legacy agricultural contracts, and exchanges set limits for the others.
• Bona fide hedges, spreads and certain other positions can qualify for exemptions.

What a position limit is

A position limit is a ceiling on how large a net position a trader can hold in a given contract, expressed in contracts or an equivalent. A trader who holds a position above the limit, unless exempt, is in violation and can face enforcement action from the exchange, the CFTC or both. Because limits apply to a trader’s aggregate position across accounts under common ownership or control, splitting positions among affiliates does not avoid them.

Limits have a long history in agricultural markets, where concerns about corners and squeezes motivated early regulation. The post-crisis reforms expanded the statutory direction to set limits across energy and metals contracts too. The statute directs the CFTC to establish limits to help prevent excessive speculation, to deter manipulation, to ensure sufficient market liquidity for bona fide hedgers and to keep the price discovery function of markets intact.

Spot month and non-spot month

The spot month is the period in which a futures contract is nearing delivery. Positions in that window can influence the price at which physical commodities change hands, so limits are tighter. The CFTC says federal spot-month limits apply to all 25 core referenced futures contracts and their referenced contracts, are set at or below 25 percent of estimated deliverable supply, and generally apply across exchanges and the over-the-counter swaps market.

Outside the spot month, the concern shifts to how large speculative positions can affect price discovery and liquidity. Under the current federal framework, non-spot-month limits apply only to the nine legacy contracts, which include corn, soybeans, wheat and cotton. These are generally set at 10 percent of open interest for the first 50,000 contracts, plus 2.5 percent of open interest beyond that. For other agricultural, metals and energy contracts, the exchanges set limits or accountability levels in non-spot months.

Federal and exchange limits

Exchanges that list futures are required to set their own position limits or accountability levels as part of their duties to prevent manipulation. Where the CFTC has a federal limit, the exchange limit may be the same or lower. A trader may therefore be subject to a federal limit, an exchange limit or both, and each has its own exemption process. The CFTC notes that exemptions from exchange-set limits must be requested separately from the exchange.

An accountability level differs from a hard limit. A trader who exceeds an accountability level is not automatically in violation but must provide information on request and may be asked to reduce the position.

Bona fide hedging exemptions

The central exemption is for bona fide hedging. The CFTC says a bona fide hedge must substitute for a transaction in the physical marketing channel, be economically appropriate to reducing price risk, and arise from a change in value of actual or anticipated assets, liabilities or services. Pure risk management positions, such as a financial firm taking a broad commodity exposure for a client, generally do not qualify.

Two paths exist:

• Enumerated hedges. These are listed in an appendix to the CFTC’s Part 150 regulations. A holder does not need to apply to the Commission for these, though it must still seek exemptions from exchange-set limits.
• Non-enumerated hedges. These go through a streamlined process in which a single application is made to the exchange, and the Commission can review it within ten business days (two for sudden or unforeseen needs). A trader with an urgent need may file a retroactive application within five business days after exceeding a limit.

For a company building a hedging strategy, the lesson is that the position needs to match a real exposure. A producer selling forward its expected output, or a processor buying futures to cover anticipated purchases, fits the concept. A position that is larger than the exposure, or that is unrelated to the physical business, does not.

Other exemptions

Spread exemptions. Recognized spread strategies, such as calendar spreads or crack spreads, can be exempt. The CFTC says such exemptions are self-effectuating for federal limits if the position fits the definition, though the trader must separately apply to the exchange.

Financial distress exemptions. These allow a trader to exceed limits to take on another participant’s positions during a potential default or bankruptcy, and the Commission decides them case by case.

Reporting. Large traders report positions to exchanges and the CFTC, which lets surveillance staff monitor concentrations. Reporting thresholds are separate from limits.

Why limits are debated

Supporters argue limits protect against corners, squeezes and distortions, especially as delivery nears. Critics argue that excessive restrictions can reduce liquidity, raise hedging costs and push activity to venues outside the US. Empirical research on how much speculative activity affects prices is mixed. For that reason, the federal framework has gone through several rounds of proposal and revision, and market participants should assume it may change again.

How limits connect to risk management inside a firm

Compliance teams treat position limits as a hard operating constraint. A trading desk typically monitors aggregate exposure across entities in real time, compares it with both federal and exchange limits, and escalates before a threshold is reached. Firms that rely on hedge exemptions keep documentation showing the physical exposure behind each position, because an exchange or the CFTC may ask for it. Treasury staff at commercial companies often coordinate with compliance so that a hedging program built for accounting or budgeting purposes also fits the regulatory definition of a bona fide hedge. A program that fits one definition does not automatically fit the other.

Aggregation rules add another layer. A parent company that controls several funds or subsidiaries generally has to count their positions together, unless a narrow disaggregation exemption applies. Independent account controllers and certain separately managed accounts are treated under specific provisions. The point for readers is that the entity named on a trading account is not always the entity the rules look at.

Common misconceptions

“Limits apply to everyone equally.” Hedgers with qualifying exposure can hold positions above the speculative limit. The limit targets speculation.

“Federal limits cover every commodity.” Federal limits attach to a defined list of contracts. Exchanges set limits or accountability levels for the rest.

“Limits are only about farm goods.” The federal list includes energy and metals contracts, and spot-month limits apply there.

“A hedge exemption lasts forever.” Exemptions rest on the underlying exposure. If the exposure goes away, the exemption basis does too.

A worked example

Suppose a processor expects to buy a large quantity of a physically delivered commodity over the next six months. It buys futures to lock in part of its costs. Because the position substitutes for later cash purchases and is sized to the expected need, it may qualify as a bona fide hedge. If the processor’s hedge is of a type listed in the CFTC’s enumerated categories, no application to the Commission is needed for federal purposes, but the processor still checks the exchange’s rules and applies there where required.

Now suppose a trading firm without any physical exposure builds a similar position in the spot month. That position is speculative. It would count against the federal spot-month limit, and the firm would need to keep it under the cap or face potential enforcement.

FAQ

Who sets position limits?

Both the CFTC and the exchanges. The CFTC sets federal limits for a defined list of contracts under Part 150 of its regulations. Exchanges set their own limits and accountability levels.

What is deliverable supply?

It is the estimated quantity of a commodity that can be delivered under a futures contract. Federal spot-month limits are tied to a share of it.

Do position limits apply to swaps?

Federal limits cover economically equivalent swaps linked to the core referenced futures contracts. Positions in futures and equivalent swaps are generally aggregated.

What happens if a trader exceeds a limit?

Exchanges and the CFTC can investigate and impose penalties. Some violations are handled through exchange disciplinary processes, and others through CFTC enforcement.

Where do I find the current limits?

The CFTC maintains a position limits page, and the exchanges publish limits in their rulebooks and notices. Limits and contract lists can change, so check the current versions.
