The Phillips Curve Meets the Reality of India's Informal Economy
The relationship between inflation and unemployment is
traditionally explained through the Phillips Curve, which suggests that
inflationary pressure tends to increase when unemployment falls and economic
activity approaches its productive capacity. When more people find employment,
household incomes rise, consumption increases and businesses gain greater
pricing power. Conversely, rising unemployment generally weakens purchasing
power, reduces consumption and moderates inflation. However, this relationship
becomes considerably more complicated in India, where nearly 90% of employment
is estimated to be informal. Unlike developed economies, where formal
employment, wages and unemployment insurance provide relatively reliable
indicators of economic conditions, India's labour market includes casual
workers, self-employed individuals, agricultural labourers, unpaid family
workers and people engaged in irregular employment. A person may be officially
employed but earn insufficient income to support consumption, while another may
be working fewer hours than desired. Consequently, a low unemployment rate does
not necessarily indicate a tight labour market or strong aggregate demand.
India's Periodic Labour Force Survey has reported unemployment of approximately
3.1% under the usual-status measure, while unemployment among young people aged
15–29 has been considerably higher, around 9.9%. Graduate unemployment has also
remained a concern. These differences demonstrate why the headline unemployment
rate cannot independently explain the relationship between inflation and
economic activity. India's inflation problem must therefore be examined through
employment quality, real wages, household purchasing power, underemployment and
the distribution of income rather than simply the number of people classified
as employed.
Why Unemployment Does Not Always Control
Inflation
In an economy dominated by informal employment,
inflation can remain elevated even when unemployment is relatively high. This
happens because food, fuel, housing and essential services account for a
substantial share of household expenditure, particularly among lower-income households.
Rural households spend approximately 47% of their monthly consumption
expenditure on food, compared with around 40% for urban households. Therefore,
an increase in food prices can reduce disposable income and consumption of
other goods without necessarily producing a corresponding increase in measured
unemployment. Equally, higher prices can encourage workers to demand higher
wages, but informal businesses may lack the financial capacity to increase
wages proportionately. The result is a decline in real incomes rather than a
conventional wage-price spiral. India's average daily earnings for casual
labour increased from approximately ₹430 in 2024 to ₹453 in 2025, but nominal
wage increases do not necessarily represent improvements in purchasing power
when essential prices rise. Furthermore, self-employed workers may respond to
declining demand by accepting lower margins, working longer hours or employing
family members without additional compensation. These adjustments conceal
economic distress in conventional labour statistics. Thus, unemployment may not
increase even when household consumption weakens significantly. The
relationship between inflation and unemployment in India is therefore mediated
by real wages, informal employment, productivity and the capacity of businesses
to pass higher costs to consumers.
How the RBI Distinguishes Transitory
Inflation from Embedded Inflation
The Reserve Bank of India cannot depend exclusively on
unemployment figures to determine whether inflation is temporary or becoming
entrenched. Instead, it must examine the composition, persistence and
transmission of price increases. India's flexible inflation-targeting framework
aims at 4% consumer price inflation, with a tolerance band of 2–6%. A temporary
increase in vegetable prices caused by an adverse monsoon, supply disruption or
seasonal shortage does not necessarily justify a monetary tightening cycle. The
RBI must assess whether such increases are spreading into other goods and
services, influencing wages, changing business pricing decisions and altering
household expectations. Food inflation is particularly important because food
occupies a large share of household budgets and influences perceptions of the
cost of living. However, the persistence of core inflation, which excludes food
and fuel, can provide additional evidence of broader price pressures. The RBI
also examines the breadth of inflation across consumption categories, inflation
momentum, input costs, capacity utilisation, credit growth, liquidity conditions,
wage movements and international commodity prices. If headline inflation rises
because of a temporary supply shock while core inflation remains contained and
demand is weak, the appropriate response may be to avoid unnecessary
interest-rate increases. But if businesses repeatedly revise prices upwards,
workers begin demanding compensation for anticipated inflation and households
expect prices to continue rising, a temporary shock can become embedded in the
economy. The distinction is not simply between food inflation and core
inflation; it is between an isolated change in relative prices and a persistent
change in the economy's price-setting behaviour.
Inflation Expectations May Be More
Informative Than Unemployment
When unemployment statistics are unreliable indicators
of economic slack, inflation expectations become particularly important for
monetary policy. The RBI conducts household inflation expectation surveys to
understand what consumers expect prices to do over the coming three months and
one year. It also conducts consumer confidence surveys, professional forecaster
surveys, industrial outlook surveys and capacity utilisation assessments. These
indicators help identify whether inflation is changing actual economic
behaviour. For instance, if households expect higher prices, they may advance
purchases, reduce savings and increase present consumption. Businesses
anticipating higher future costs may increase prices today, even before their
input costs rise. Workers may seek higher wages to protect purchasing power,
while lenders may demand higher interest rates to compensate for expected
inflation. Such behaviour can make inflation self-reinforcing. The distinction
between adaptive and forward-looking expectations is important here. Adaptive expectations
are formed largely from past inflation, whereas rational or forward-looking
expectations incorporate available information about future economic conditions
and policy responses. In practice, households and businesses use a combination
of both. If the RBI credibly communicates that temporary supply shocks will not
be allowed to become persistent inflation, it can influence future
price-setting decisions without necessarily causing a large increase in
unemployment. This is particularly valuable in India, where raising interest
rates cannot directly create additional food supplies or immediately improve
agricultural productivity.
Interest Rates, Savings and the
Supply-Side Response
The relationship between interest rates, savings,
consumption and inflation is more complex than simply reducing demand through
expensive borrowing. Higher interest rates can encourage households to save
rather than consume, moderate credit-financed expenditure and reduce excessive
demand. They can also strengthen the incentive for financial savings, improving
the availability of funds for productive investment. However, higher borrowing
costs can simultaneously discourage businesses from expanding capacity,
increasing inventories or investing in new production. If supply is already
constrained, excessive monetary tightening may reduce production and employment
without proportionately reducing inflation. The RBI must therefore distinguish
demand-driven inflation from supply-driven inflation and assess how monetary
policy can influence their interaction. An economy with weak purchasing power,
considerable underemployment and limited wage growth may not require aggressive
demand suppression simply because food inflation has temporarily increased.
Instead, monetary policy should prevent temporary price increases from changing
long-term inflation expectations, while fiscal and supply-side policies improve
storage, transportation, agricultural productivity and market availability. The
objective should be to encourage savings, stabilise expectations and create
conditions in which businesses can increase supply without anticipating
continuously rising prices. Lower expected inflation can also reduce the
nominal interest rates demanded by lenders over time, improving investment conditions
and supporting employment.
The RBI's Real Challenge: Controlling
Expectations Without Destroying Employment
India needs a monetary-policy framework that recognises the limitations of conventional unemployment statistics. The RBI should not interpret low unemployment as conclusive evidence of excessive demand, nor should it interpret weak employment conditions as proof that inflation will automatically decline. A better assessment combines real wage growth, household consumption, labour-force participation, employment quality, capacity utilisation, credit expansion, core inflation and inflation expectations. The September 2026 CPI inflation rate of 5.54%, with food inflation at 7.74%, illustrates why the composition of inflation matters as much as the headline number. At the same time, the 2025 PLFS unemployment rate of 3.1% among persons aged 15 and above does not establish that all sections of the labour market enjoy adequate employment or purchasing power. The RBI's ultimate responsibility is not to eliminate every temporary movement in prices through interest-rate changes, but to prevent such movements from becoming permanent expectations. Monetary credibility can reduce the incentive to purchase today merely because prices are expected to be higher tomorrow. This can moderate present demand, encourage savings and give producers greater confidence to invest in additional capacity. India's monetary-policy success should therefore be judged not merely by whether inflation returns to the 4% target or unemployment remains low, but by whether stable expectations allow real incomes, productive investment, employment and supply to grow together. In an informal economy, the most important signal may not be how many people are unemployed, but what households and businesses believe will happen to their incomes, prices and borrowing costs tomorrow.
