How Does the Margin Requirement for a Futures Contract Influence the Effective Spread?

Margin requirements, the collateral needed to hold a futures position, influence the cost of trading. Higher margin requirements mean a higher capital cost for market makers.

To compensate for this increased capital expenditure, market makers may quote a wider bid-offer spread. Conversely, lower margin requirements reduce the capital cost, allowing market makers to quote a tighter spread.
