Deribit’s Position-Sensitive Margin Leverage Model for Futures

Summary

The article outlines a planned change to initial and maintenance margin calculations for standard margin accounts on Deribit. It applies to futures and perpetual contracts; options use a separate calculation that the article says will remain unchanged. The new approach makes available initial-margin leverage depend on the instrument tier and account position size, using parameters for starting and ending leverage, the point where leverage begins to decline, the rate of decline, and a maximum position size.

A BTC perpetual example assigns the instrument to tier 1 and uses a 150 BTC position to illustrate an available leverage estimate of about 27.73 times. The article explains how the parameters give the exchange control over leverage across different position sizes and impose a hard size cap. However, the supplied text omits the formulas and tier tables needed to reproduce the calculation or compare instruments. It describes an August 2026 effective date and exchange-specific rules, so the example should not be treated as a general margin formula or current universal standard.

Key ideas

• The revised model applies to futures and perpetuals in standard margin accounts, while options calculations remain separate.
• Available initial-margin leverage varies with position size and the instrument’s assigned tier.
• Four parameters shape leverage limits and how quickly leverage declines as positions grow.
• A maximum position size sets a hard account-level limit for each instrument.
• The article’s omitted formulas and tables limit independent verification of its numerical example.
