Explanation

Daily mark-to-market settlement in exchange-traded derivatives primarily reduces counterparty credit risk.

Key Concepts:

1. Mark-to-Market (MTM) Settlement:

   • Exchange-traded derivatives require daily settlement of gains and losses
   • This means positions are revalued daily based on current market prices
   • Any gains or losses are settled immediately through margin accounts

2. Counterparty Credit Risk Reduction:

   • By settling gains/losses daily, the exposure between counterparties is minimized
   • The maximum potential loss is limited to one day's price movement
   • This prevents the accumulation of large unpaid obligations
   • The clearinghouse acts as the central counterparty, guaranteeing trades

3. Why Not Other Options:

   • Basis Risk: Refers to the risk that the hedge instrument and the underlying asset don't move perfectly together. Daily settlement doesn't reduce this.
   • Liquidity Risk: Daily settlement might actually increase liquidity requirements since participants need to maintain sufficient margin.

4. Exchange Mechanisms:

   • Clearinghouses require initial and maintenance margins
   • Daily settlement ensures that losses are covered before they become too large
   • This is a key feature distinguishing exchange-traded from over-the-counter derivatives

Conclusion:

Daily mark-to-market settlement is specifically designed to mitigate counterparty credit risk by ensuring that losses are settled promptly, preventing the buildup of large credit exposures between trading parties.
