A cash rate is the declared rate used to model the return on a cash or financing component.

Also known ascash return ratecash benchmark rate

Definitions

In plain terms

A volatility-control index may allocate part of its exposure to a cash component whose return follows this rate.

Technical

The field requires currency, source, tenor, observation and effective times, day count, compounding, spread, calendar, missing-fixing policy, and publication lineage.

Scope

Cash is not universally risk-free, and different strategies select different rates.

Examples

  • A governed methodology records cash rate with its source, cutoff, units, parameters, and effective version.

Common misconceptions

  • Cash Rate does not have one universal implementation without the declared methodology, data basis, and constraints.
