India’s New Index of Services Production (ISP): A Major Upgrade to Economic Measurement

Introduction

India is set to introduce a new economic indicator called the Index of Services Production (ISP), marking a significant milestone in the country’s economic data framework. Scheduled for launch in July 2026, the ISP will provide a monthly measure of output in the services sector, similar to how the Index of Industrial Production (IIP) tracks manufacturing and industrial activity.

The introduction of the ISP is being viewed as one of the most important reforms in India’s economic statistics system in recent years. Since the services sector contributes more than half of India’s Gross Domestic Product (GDP), policymakers, economists, businesses, and investors have long felt the need for a reliable and timely indicator to track its performance.

Why India Needs the ISP

For decades, India has relied on the Index of Industrial Production to assess the health of the industrial sector. However, despite the services sector becoming the largest contributor to the economy, there was no equivalent monthly indicator available.

Economists often depended on indirect measures such as Purchasing Managers’ Index (PMI) surveys, GST collections, bank credit growth, and sector-specific data to estimate services activity. While useful, these indicators only provided partial insights and did not directly measure production in the services sector.

The ISP aims to bridge this gap by offering a comprehensive and standardized measure of services output across various industries.

Understanding the Services Sector

The services sector includes a wide range of economic activities that do not involve manufacturing physical goods. It covers industries such as:

• Banking and financial services
• Insurance
• Retail and wholesale trade
• Transport and logistics
• Telecommunications
• Hotels and restaurants
• Real estate services
• Professional consulting
• Information technology services
• Entertainment and recreation

Over the last three decades, India’s economic growth has increasingly been driven by these sectors. The rise of IT services, digital payments, e-commerce, telecommunications, and financial services has transformed the country’s economic structure.

Today, services account for more than 50 percent of India’s GDP and contribute significantly to employment, exports, and tax revenues.

How the ISP Will Work

The new index will be compiled using a combination of modern data sources. Instead of depending solely on surveys, the government plans to use administrative and digital datasets that provide real-time information about economic activity.

Some key data sources include:

GST Network Data

Goods and Services Tax filings generate vast amounts of business information every month. These records can help estimate output levels in sectors such as retail, logistics, and professional services.

Regulatory Data

Various regulators and government departments collect data from industries under their supervision. These records will contribute to measuring sector-specific performance.

Enterprise Surveys

Official surveys conducted by government agencies will supplement administrative data and improve the accuracy of estimates.

By combining these sources, the ISP will provide a more comprehensive picture of service-sector performance.

Benefits of the New Index

Better Economic Monitoring

The biggest advantage of the ISP is that it will enable policymakers to monitor the economy more effectively. Since services form the largest part of GDP, tracking their monthly performance will improve understanding of economic trends.

Improved GDP Estimates

GDP calculations depend heavily on estimates and projections. With more frequent and reliable services data available, national income calculations are expected to become more accurate.

Stronger Policy Decisions

The Reserve Bank of India (RBI) and the central government rely on economic indicators while making policy decisions. Better data can lead to more informed choices regarding interest rates, fiscal policies, and development programs.

Increased Investor Confidence

Investors seek reliable economic information before making decisions. A monthly services production index can help domestic and foreign investors assess economic conditions with greater confidence.

Enhanced Transparency

The ISP will improve transparency by providing a standardized benchmark for measuring service-sector growth. This can reduce uncertainty and improve economic forecasting.

Impact on Businesses

Businesses operating in the services sector stand to benefit from the introduction of the ISP. Monthly data can help companies understand broader market trends and benchmark their performance against industry growth.

For example, banks can assess whether financial services activity is expanding or slowing. Retail companies can evaluate consumer demand patterns, while logistics firms can gauge transport-sector momentum.

The availability of a trusted national indicator can also support strategic planning and investment decisions.

Challenges in Measuring Services

Measuring services output is significantly more difficult than measuring industrial production.

In manufacturing, production can often be counted in physical units such as tonnes of steel, cars produced, or electricity generated. Services, however, are intangible and often harder to quantify.

For example:

• How does one measure the output of a consulting firm?
• How should digital services be valued?
• How can healthcare and education services be tracked accurately?

These challenges have delayed the introduction of a comprehensive services index for many years.

The government is therefore expected to begin with sectors where reliable data is readily available and gradually expand coverage as data quality improves.

What May Be Excluded Initially

Experts believe that some segments of the economy may not be fully represented in the first version of the ISP.

Informal services, which remain a large part of India’s economy, are difficult to measure accurately due to limited data availability.

Similarly, sectors such as health and education may require additional statistical frameworks before they can be comprehensively incorporated into the index.

Over time, however, the government is expected to refine and expand the coverage of the ISP.

A Step Toward Data-Driven Governance

The launch of the ISP reflects India’s broader push toward data-driven policymaking. The country’s growing digital infrastructure, GST ecosystem, and improved data collection capabilities have created opportunities to modernize economic measurement.

As India aspires to become a developed economy, accurate and timely economic indicators will play an increasingly important role in governance and planning.

The ISP is not merely another statistical release. It represents a modernization of how India’s largest economic sector is measured and understood.

Conclusion

The introduction of the Index of Services Production marks a historic development in India’s economic statistics framework. By providing a monthly measure of service-sector output, the ISP will fill a long-standing gap in economic monitoring.

With services contributing the majority of India’s GDP, the new index is expected to improve policy formulation, strengthen GDP estimation, enhance investor confidence, and provide businesses with valuable insights into economic trends.

As the country continues its journey toward becoming a major global economic power, the ISP could emerge as one of the most important tools for understanding and managing India’s growth story.
