Mark-to-Market Accounting
Mark-to-market accounting is a method of measuring the fair value of accounts that can fluctuate over time, such as assets and liabilities. In the derivatives market, this involves revaluing all open positions based on the current market price at the end of each trading day or in real-time.
This practice ensures that financial statements and account balances reflect the most accurate current value of a position. By marking to market, clearing houses can identify risk exposure immediately and demand additional margin if necessary.
This prevents the buildup of hidden losses that could threaten the solvency of a trading firm. In the context of cryptocurrencies, mark-to-market is performed continuously because markets never close and volatility is high.
This constant valuation is vital for the automated liquidation engines used by many crypto exchanges. It creates transparency and trust between the exchange and the trader, as both parties are aware of the exact financial status of the account at any given moment.
