IOM Membership (lease) Cost Structure

IOM Membership (lease) Cost Structure

High volume traders of CME Futures products have the opportunity of reduced exchange fees by leasing a seat on the exchange.  For Equity Index Minis on the CME exchange, you can look into an IOM lease. For a complete breakdown of Membership and Lease Pricing, please reference this link:

  1. Exchange fee/NFA Fee without an exchange leased membership: $1.25/contract
  2. Exchange fee/NFA Fee with an exchange leased membership: $0.48/contract
    1. As a IOM leased member, you do not pay the NFA fee

This is a savings of $0.77 per contract!* To calculate the amount of money you will receive with a membership, take your daily or monthly volume and multiply that number by $0.77.  This final number will be the amount you save by leasing an IOM seat. 

Upfront Cost:

  1. $2,000 nonrefundable application fee
    1. This will be paid off after 2,598 contracts traded (2598 * $0.77 = $2000)
  2. Monthly lease cost (normally between $200-$400/month)

You can also receive discounts based on average daily volume.  Below is an example of the E-Mini Equity Volume Discount (Individual) for the month of May ’20. Volume between 0 -5,000 would not receive any discount but once you reach the next tier (volume between 5,001 – 35,000) would receive a discount of $0.16 per contract.
