The correct answer is C. Financial measures.

In designing a Contingency Funding Plan (CFP), early warning indicators (EWIs) are crucial for identifying emerging liquidity stress. According to best practices and regulatory guidelines in liquidity risk management, these indicators are typically categorized into three main structural groups to ensure a comprehensive view of potential stress:

1. Macro-environment measures: Focuses on systemic risks and broad economic factors (e.g., changes in interest rates, GDP trends, and overall systemic market liquidity).
2. Industry measures: Focuses on trends and events affecting the specific sector or the banking industry as a whole.
3. Institution-specific measures: Focuses directly on the bank's own health and operations (e.g., asset quality deterioration, negative earnings, funding concentrations, credit rating downgrades, and stock price movements).

"Financial measures" is not classified as a distinct category of early warning indicators within standard CFP frameworks, as specific financial metrics are intrinsically subsumed under institution-specific measures.
