India will incorporate data from its upcoming All-India Debt and Investment Survey (AIDIS) into GDP estimates for the fiscal year ending March 2028. The survey, conducted from July 2026 to June 2027, will provide crucial information on household assets and liabilities to refine estimates of gross fixed capital formation, a key GDP component. This move aligns with international standards and supports the revision of India's GDP base year to 2022-23, with new series data expected February 27, 2026.
