financeparamsyaml

Financeparamsyaml is a human-readable, YAML-based configuration format used to capture financial parameters for modeling, forecasting, and simulation in software applications. It provides a structured way to represent inputs such as interest rates, cash flows, discount factors, and market assumptions, enabling repeatable analyses and shareable configurations across teams. While not a formal international standard, financeparamsyaml is employed in several financial engineering and fintech projects as a lightweight alternative to hard-coded values.

It typically organizes data into top-level sections such as metadata, terms, cash_flows, calculations, and risk. Common fields include currency, locale, time_zone, start_date, end_date, rate_type, interest_rate, compounding, payment_frequency, and horizon. The cash_flows section often contains a list of date-value pairs or scheduled payments; the calculations section names models or methods (for example, present_value, net_cash_flow) and associated parameters; the risk section may specify metrics like VaR, CVaR, and confidence_level. YAML’s indentation and support for comments aid readability.

Tools can parse YAML and map it to language-native data structures, enabling automation in Python, R, or Java. Validation can be done with JSON Schema or custom validators to enforce required fields, value ranges, and mutual exclusions. Potential drawbacks include YAML’s whitespace sensitivity, parser differences, and security considerations when loading untrusted files.

While not a widely formalized standard, financeparamsyaml serves as a pragmatic convention for configuring financial models. It complements other data interchange formats like JSON or CSV and can be extended with versioning and metadata to support collaborative workflows.
