Revamping Household Savings Measurement: SEBI's New Methodology for Securities Market Data and Its Macroeconomic Impact
Overview
One of the foundational pillars of any economy's health is the rate at which its households save and deploy those savings productively. In India, this measurement has historically relied on a combination of actual data and estimation techniques — particularly when it came to quantifying how much households invest through the securities market. A recent methodological overhaul, jointly developed by SEBI in coordination with RBI and MoSPI, has fundamentally changed how these savings are measured, resulting in a more granular, accurate, and policy-relevant picture of household financial behaviour.
This article explores the nature of that methodological shift, the new data it has produced, and what it means for India's macroeconomic indicators — particularly the gross savings to GDP ratio.
Background: Why Savings Measurement Matters
Economists across schools of thought have long recognised the centrality of savings in economic development. From a Keynesian perspective, savings represent the residual after consumption expenditure is subtracted from income. From a monetarist standpoint, savings reflect what remains of disposable income once personal consumption has been accounted for. Regardless of the framework, national savings serve as the bedrock of capital formation — and capital formation drives growth.
India's national savings are broadly generated from three distinct sectors:
- Household sector
- Private corporate sector
- Public sector
Among these, the household sector has consistently been the dominant contributor to India's gross domestic savings. Within household savings, there exist two broad categories:
Physical Savings
Assets in tangible form — real estate, gold, precious metals, and similar holdings.
Financial Savings
Savings deployed in financial instruments — currency, deposits, shares and debentures, government securities, small savings, insurance funds, provident and pension funds, and increasingly, market-linked instruments.
While physical assets such as gold and real estate have traditionally dominated Indian household portfolios, financial instruments have been gaining significant traction in recent years. This shift has been accelerated by government policy initiatives, greater financial inclusion, digital banking penetration, and tax incentives linked to financial investments.
Key Insight: The rapid growth in individual participation in the securities market — particularly following the COVID-19 pandemic — made it increasingly important to revise savings measurement frameworks to capture actual investment flows rather than rely on broad statistical estimates.
The Limitations of the Earlier Methodology
Before the revision, data on household savings flowing into the securities market was published by RBI, drawing on a methodology that involved the following approximations:
- 35% of public and rights issuances in equity was attributed to households
- 40% of public issuances in corporate debt was attributed to households
- Mutual fund investments were captured at actuals from SEBI data
These figures were then incorporated by MoSPI into its computation of gross savings for the economy.
Critical Gaps in the Old Framework
The earlier approach suffered from several material limitations:
- Primary market focus only — Secondary market transactions were entirely excluded
- Incomplete primary market coverage — Private placements of debt and preferential equity issuances were not accounted for
- No coverage of new-age instruments — Real Estate Investment Trusts (REITs), Infrastructure Investment Trusts (InvITs), and Alternative Investment Funds (AIFs) were absent
- Estimation dependency — The use of fixed percentage proxies (35% for equity, 40% for debt) introduced systematic inaccuracies
- Exclusion of NPISHs — Non-Profit Institutions Serving Households were not recognised as a distinct investor category
These gaps meant that the actual volume of household savings flowing into the securities market was being consistently and materially understated in national accounts.
