Why Is MTM Necessary Even for Physically-Settled Contracts?

MTM is necessary for physically-settled contracts for the same reason as cash-settled ones: to manage counterparty credit risk. While the final delivery is physical, the contract's daily change in value represents a financial gain or loss that must be settled daily in cash to ensure the financial integrity of the trading parties and the clearinghouse, preventing large defaults.
