Definition
A Variable Price Limit is a circuit breaker mechanism used in commodities futures markets that allows trading to resume within an expanded set of upper and lower price limits after a specific futures contract has hit its predetermined limit price. This system aims to manage volatility and provides a structured approach for the market to adjust to sudden price movements.
| Variable Price Limit | Fixed Price Limit |
|---|---|
| Allows for expanded limits after the initial limit is reached. | Set specific upper and lower price thresholds that do not change. |
| Adjusts based on market dynamics. | Remains constant regardless of market conditions. |
| May vary across different exchanges and commodities. | Universally applicable until the next trading session. |
Examples
- If the limit price for gold futures is $1,800 per ounce and trading hits this limit, a variable price limit may allow subsequent trading to occur within a new range, like $1,750 to $1,850, on subsequent sessions.
- Agriculture commodities like corn might have variable price limits set by specific exchanges, changing according to market conditions, while energy commodities like crude oil may have different limits or none at all.
