IMF Analysis: Central Banks Must Integrate Private 'Alternative Data' to Combat Economic Lag

The IMF IMF’s Finance & Development feature titled “Alternative Data and Monetary Policy” argues that central banks must actively incorporate nontraditional data sources—data not originally created for official economic statistics, but repurposed from private business or government programs—to effectively manage the modern economy.
Key Advantages of Alternative Data for Central Banks:
Timeliness and Granularity: Alternative data is often timelier (days/weeks vs. months for official statistics) and more granular, which is crucial for accurately and quickly assessing business cycle turning points.
Example: Weekly payroll data provided early insight into the rapid employment decline during the COVID-19 pandemic, weeks before official reports.
Example: Granular, real-time data on credit/debit card transactions and online price indices can be used to track the real-time effects of specific policies, like tariffs, on consumer prices.
Filling Gaps: It fills gaps caused by rising costs and falling response rates to national surveys, which reduce the precision and reliability of traditional estimates.
Policy Assessment: Nontraditional data helps officials assess the distributional consequences of monetary policy, such as showing that lower-income and minority borrowers were less likely to refinance when interest rates fell during the pandemic.
Challenges and Policy Requirements for Central Banks:
Transparency and Accountability: Relying on private data sources not widely available to the public erodes transparency, which is critical for central bank accountability. Outsiders cannot verify the central bank’s analysis.
Data Integrity and Continuity: Private companies may abruptly stop sharing data or sharply raise prices, threatening the continuity and cost-effectiveness of official statistics.
Noise and Bias: Alternative data is often a by-product of private business activity, carrying its inherent biases and lacking the long continuity and robust methodology of official sources.
Policy Relevance
This analysis is critically relevant to the RBI, MoSPI, and India’s overall digital finance policy. Given the massive scale of India’s Digital Public Infrastructure (DPI)—including UPI, GSTN, and Account Aggregator (AA)—the RBI has an unprecedented opportunity to harness high-frequency, granular data for real-time monetary policy calibration. Policy priorities must focus on formalizing data-sharing agreements with robust governance, ensuring that the use of private or alternative data does not compromise transparency and public trust, and strengthening the institutional capacity of official statistical bodies.
What is Alternative Data (Nontraditional Data)?→ Alternative Data refers to information sources that were not created for the purpose of making economic statistics but are repurposed from running a business or government program, such as: payroll processing data, credit card transactions, online retailer price indices, and real-time shipping container movements. This data is used to supplement traditional statistics for faster, more granular economic analysis.
Relevant Question for Policy Stakeholders: What governance framework should the RBI establish to ensure that the reliance on private and proprietary ‘Alternative Data’ enhances monetary policy transparency, rather than eroding public trust and accountability?
