Context: Inflation in India has fallen sharply in recent months. CPI inflation was at just 2.07% in August 2025 and WPI inflation at 0.52%. While this trend is positive for consumers, it poses challenges for the Union Government’s fiscal arithmetic and Budget management.
Relevance of the Topic: Prelims: Concept of Inflation; Low Inflation: Issues and Implications.
Inflation refers to the sustained rise in the general price level of goods and services. While high inflation erodes purchasing power, moderate inflation is considered desirable as it supports growth and helps maintain fiscal balance.
However, persistently low inflation, as seen in India in 2025 with CPI inflation at 2.07% and WPI inflation at 0.52%, poses distinct challenges for the economy and government finances.
Issues with Low Inflation
- Slower Nominal GDP Growth: The government’s fiscal calculations depend on nominal GDP, which includes both real growth and inflation. With prices barely rising (stagnant) due to lower inflation, nominal GDP growth has slowed falling below the 10.1% assumed in the Union Budget 2025-26.
- Weaker Tax Revenues: Tax collections are directly linked to nominal GDP growth. Lower inflation means slower growth in the value of goods and services i.e., weak GST and excise revenues. In April-July 2025, gross tax revenue grew by only 1% year-on-year, while net tax revenue declined by 7.5%.
- Fiscal Deficit Ratios Under Strain: The fiscal deficit and debt are measured as a share of nominal GDP. With a lower GDP base, deficit and debt ratios look worse even if the government’s borrowing remains constant. This risks India’s FRBM targets (3% fiscal deficit in the medium term, 60% debt-GDP ceiling).
Implications of Persistently Low Inflation:
- Budgetary Stress: Lower tax revenues make it harder for the government to meet Budget targets and maintain fiscal discipline. Budget credibility is undermined if revenue projections repeatedly fall short.
- Borrowing vs. Spending Cuts: The government may struggle to meet its revenue targets, which could force either higher borrowing or cuts in planned spending.
- Weak Demand and Employment: Persistently low inflation often reflects weak demand, which can delay job creation and wage growth.
- Discouraged Private Investment: Weak demand discourages private investment despite high corporate profits.
- Vicious Cycle Risk: In the long run, prolonged low inflation can create a vicious cycle of weak demand, lower revenues, and constrained fiscal space.
- Monetary Policy Challenge: RBI has an inflation targeting mandate (4% ±2%). Too-low inflation limits its ability to cut rates (real interest rates rise when inflation falls).
- Agricultural distress: India’s CPI is food-heavy (~45%). Weak food inflation reflects rural distress and falling farm incomes.
Is Low Inflation always Bad?
- Low inflation is not always harmful. If it is driven by productivity gains, technological innovation or supply-side efficiencies, it benefits consumers by reducing costs without damaging fiscal health.
- If caused by weak demand and poor investment sentiment or agricultural distress, it signals structural weakness, reduces revenues, squeezes fiscal space, and slows down both growth and revenues.
For sustainable growth, India requires moderate inflation driven by healthy demand and productivity improvements.
