India’s private sector economy maintained strong expansion momentum in May 2026 but showed early signs of strain from the Iran war’s cascading effects, with the HSBC Flash India Composite PMI Output Index coming in at 58.1 — marginally down from 58.2 in April — while manufacturing activity hit its second-weakest reading in nearly four years and input cost inflation surged to its highest level since July 2022.
The headline numbers
The Composite PMI of 58.1 signals continued marked expansion — any reading above 50 indicates growth — but the composition beneath the headline is increasingly bifurcated. Services led with a Business Activity Index of 58.9, slightly up from April’s 58.8, while manufacturing lagged with an Output Index of 56.6 down from 56.9, and the headline Manufacturing PMI falling to 54.3 from 54.7 — its second-weakest reading in close to four years, ahead only of March 2026.
Data were collected between May 8 and 18, 2026 — squarely within the period of peak rupee stress and elevated oil prices from the Hormuz crisis.
Manufacturing: The warning signs
The manufacturing sector is where the Iran war’s economic damage is most visible in the PMI data. New orders among goods producers expanded at their second-weakest pace in close to four years. New export orders — a critical forward indicator for industrial health — recorded their weakest expansion in 19 months, with goods producers seeing the second-slowest rise in international sales since September 2024.
Survey panellists explicitly cited competitive pressures, challenging demand conditions, disruptions to travel, and the war in the Middle East as factors dampening sales. This is the first Flash PMI release in which the Iran war appears as a named demand-side headwind from the businesses surveyed — a signal that the macroeconomic transmission from the conflict into India’s real economy is becoming measurable at the firm level.
Despite the demand softness, manufacturers continued aggressive inventory building — buying levels rose at the fastest pace in three months, stocks of purchases increased at the fastest rate in three months, and finished goods inventories rose for a second consecutive month at the strongest pace in 11 years. HSBC’s Chief India Economist Pranjul Bhandari noted this stockpiling dynamic as a key support for the manufacturing PMI even as new orders and output growth moderated.
The cost pressure problem
This is the most concerning element of the May flash data. Input price inflation at the composite level reached its second-highest level in nearly three years. Within manufacturing specifically, input price inflation was the steepest since July 2022 — a four-year high. Survey participants reported higher prices for energy, food, fuel, gas, iron, leather, oil, plastics, rubber, steel, and transportation — a list that reads as a direct inventory of the commodities most exposed to the Hormuz disruption and rupee depreciation.
The inflationary squeeze is being partially absorbed by companies rather than fully passed through to consumers. Output charges — the prices firms charge their customers — rose at the weakest pace since January, considerably softer than the input price acceleration. This means Indian businesses are compressing their margins to remain competitive rather than triggering a consumer inflation spiral — a short-term relief for the CPI but a medium-term concern for corporate earnings.
Services: The relative bright spot
Services outperformed manufacturing on both activity and inflation metrics. The Services PMI Business Activity Index ticked up to 58.9 from 58.8 — a marginal improvement in an already expansionary territory. Service providers also experienced softer inflationary pressures than manufacturers, and hired extra staff at the greatest extent in nearly a year. Business confidence across services remained strongly positive, underpinned by competitive pricing strategies, marketing efforts, and expectations of better market conditions ahead.
What it means for RBI and markets
The PMI data lands at a moment when the RBI is actively deliberating its policy toolkit — considering everything from rate hikes to overseas bond issuance to defend the rupee. The May flash reading presents a genuinely difficult picture for the central bank. Growth remains solid — a composite of 58.1 does not warrant panic — but input cost inflation at near four-year highs and weakening export orders are precisely the conditions that argue for caution on both further easing and aggressive tightening.
A rate hike in this environment risks slowing an economy that is already seeing manufacturing new orders at near four-year lows. Doing nothing risks allowing input cost inflation to eventually pass through to consumer prices — especially if the rupee remains under pressure and oil prices recover after Wednesday’s Iran deal-related crash.
The PMI data suggests India’s economy is resilient but not immune. The Iran war’s effects are visible, measurable, and building — and the second quarter of FY27 will be the real test of whether the economy can sustain 58-plus PMI readings against a backdrop of structurally elevated costs.
