Standard operational risk definitions typically include human errors (I), process failure (II), and systems failure (III). Unexpected events (IV) are generally considered in broader risk categories but are not standard elements of operational risk definitions.References:Standard operational risk definitions from Financial Risk and Regulation documents.

A clearinghouse serves several vital functions in trading activities, mainly focusing on reducing various types of risk:

Counterparty Risk:

The clearinghouse acts as an intermediary between buyers and sellers, ensuring that each party fulfills its contractual obligations. This reduces the risk that one party will default.

Liquidity Risk:

By centralizing and standardizing transactions, the clearinghouse enhances market liquidity, making it easier to buy and sell without causing significant price changes.

Operational Risk:

The clearinghouse standardizes and streamlines the clearing and settlement processes, reducing the risk of errors and delays.

Credit Risk:

The clearinghouse requires margin deposits and marks positions to market daily, minimizing credit risk.

Thus, the primary purpose of a clearinghouse is to reduce counterparty and liquidity risk.

Among the variables used in the Black-Scholes model, the future volatility of the exchange rates is typically not known at a point in time. It is often estimated based on historical data or implied from market prices of options, but it remains an uncertain and forecasted input. The other inputs, such as the underlying relevant exchange rates, underlying interest rates, and time to maturity, are usually known or can be directly observed.
