On November 7, 2025, ISDA published guidance addressing the potential delay in the release of the U.S. Consumer Price Index for All Urban Consumers (CPI-U) resulting from the current U.S. government shutdown. The guidance provides clarification on how such delays may affect the calculation and settlement of inflation-linked derivatives referencing the CPI-U.
The document outlines ISDA’s recommended approach to determining fallback procedures and valuation timelines during periods when official CPI-U data is unavailable. This publication is intended to assist market participants in maintaining consistency and minimizing disruption to contractual performance.
