KembaraXtra – Islamic Derivatives: How a Clearing House Manages Margins (Futures Contracts)


🔹 How It Works (Step-by-Step)
 
1. Initial Margin (Starting Deposit)
  • When you enter a futures contract, you must deposit an initial margin.
  • This is not a payment for the asset — it’s a guarantee.
  • The clearing house holds this money.
 
You trade a futures contract → You deposit $1,000 as initial margin.


2. Daily Price Changes (Mark-to-Market)
  • At the end of each day, the clearing house checks the market price of the contract.
  • Profits and losses are calculated daily.
If the price moves:
  • In your favor → money is added to your account
  • Against you → money is deducted


3. Variation Margin (Daily Adjustment)
  • The daily gain or loss is called variation margin.
  • The clearing house updates your account every day.
Example:
  • Day 1: You lose $100 → your balance becomes $900
  • Day 2: You gain $50 → balance becomes $950


4. Maintenance Margin (Minimum Balance)
  • The clearing house sets a minimum level called maintenance margin.
  • If your balance falls below this level, action is required.
Example:
  • Maintenance margin = $800
  • Your balance drops to $750 → below the limit


5. Margin Call (Top-Up Required)
  • If your balance is too low, the clearing house issues a margin call.
  • You must deposit more money to bring it back to the initial level.
If you don’t:
  • Your position may be closed automatically to prevent further loss.


6. Final Settlement
  • When the contract ends, the remaining balance is returned (after all gains/losses are settled).


🔹 Simple Summary
 
The clearing house:
  • collects a deposit (margin)
  • updates it daily based on price changes
  • asks for more money if needed (margin call)
  • ensures all traders can meet their obligations
