Otherwise, USDT-USD hedging volume = Min {Abs (USDT cash delta), Abs (USD cash delta)} Step 3: Calculate MR9 based on tiers. Calculate using the 3 cross-currency hedging volumes calculated in step 2: [USDT-USD hedging volume], [USDT-USDC hedging volume], [USDC-USD hedging volume], and index prices for [USDT/USD], [USDC/USD], and [USDT/USDC]. Then, refer to the different tiers in the tables below to determine the MR9 factor.
