The RBI Still Understates Inflation

The RBI’s rate hike acknowledges rising inflation, but its diagnosis understates cost pressures, uneven demand and risks from abundant liquidity.

The Reserve Bank of India has turned hawkish, but its assessment of inflation remains more reassuring than the evidence warrants. The 25-basis-point increase in the repo rate to 5.50%, accompanied by a shift to calibrated tightening, is an important reversal. Yet the policy statement does not adequately reconcile that decision with its claims of limited demand pressure and limited signs of supply pressures becoming embedded.

This is the beginning of a rate-hike cycle, not an isolated adjustment. The RBI is reversing course after cutting the repo rate by 125 basis points and injecting roughly ₹14 trillion–₹15 trillion of liquidity in 2025. Inflation expectations, widening price pressures and corporate cost data suggest the eventual policy rate could be substantially higher than today’s.

The RBI has raised its growth forecast for 2026–27 to 7.1% from 6.7%, following reported growth of 7.8% in April–June 2026–27. It has also raised its inflation projections, with the October–December forecast now at 6%, against 5.9% previously. The direction of the revision is appropriate; the question is whether its scale captures the pressures already visible.

The statement attributes rising fuel inflation largely to an unfavourable base effect, while acknowledging continuing supply-side risks from a deficient southwest monsoon, El Niño and volatile oil prices. The Indian crude basket rose from $82 in July to $116 in September. Against that backdrop, an explanation centred on base effects understates the underlying cost shock.

The demand assessment is similarly difficult to follow. Resilient consumption, strong investment, two-wheeler sales, consumer durables and bank credit support the RBI’s growth optimism. Yet it sees limited demand pressure, even while acknowledging risks from strong monetary and credit growth. These positions require a clearer explanation, particularly when inflation risks are described as evenly balanced despite the headwinds the statement itself identifies.

Hidden Inflation
Corporate accounts offer a less comforting picture. Input costs for Indian non-financial companies, particularly manufacturers, rose about 40% year on year in April–June, alongside a 45% rise in crude prices. Net sales increased by only 20–25%, while gross margins contracted by 650–800 basis points. Firms have absorbed a substantial part of the shock rather than passed it through fully.

Nor does current inflation capture the full supply shock. Food, energy and fertiliser subsidies, together with under-recoveries at oil marketing companies, have cushioned costs arising from the West Asia conflict. Petrol and diesel prices have risen only modestly. As fiscal support wanes, inflation still in the pipeline could accelerate and reinforce existing price momentum.

The RBI’s surveys show household inflation expectations well above headline inflation and still rising, while its diffusion index indicates that price pressures are spreading across more categories. Benign core inflation offers limited reassurance when the central bank’s own evidence points towards broader inflation and elevated expectations.

The apparent resilience of demand also needs qualification. It likely reflects the stronger arm of a K-shaped economy, supported by last year’s fiscal and monetary stimulus, while the weaker arm faces falling real incomes and rising prices. Treating that uneven picture as broadly resilient demand risks obscuring the strains beneath the aggregate.

Against inflation expectations above 8%, a repo rate of 5.50% remains negative in real terms. Persistently low or negative real rates can encourage leveraged spending, widen the trade deficit and accentuate inflation. We see inflation potentially reaching 6–7% in coming quarters and the terminal repo rate at 6.5–7%, implying another 100–150 basis points of increases.

Liquidity Tensions
The tightening challenge extends beyond the policy rate. FCNR(B) deposit inflows have generated about ₹5 trillion of excess liquidity. The RBI is consequently raising rates while absorbing funds attracted by its own capital-flow measures.

This creates an awkward incentive for banks. Funds placed through variable-rate reverse repos and open market operations earn roughly their funding cost, encouraging lenders to deploy them elsewhere. Competition for loans could limit how much of rising funding costs banks can pass on, squeezing margins even as policy rates rise.

Surplus liquidity also raises questions about underwriting quality. The proposed technical committee on financial markets, intended to improve information on risks across banks, markets and non-bank lenders, is therefore prudent. But granular monitoring may need stronger policy guardrails when abundant liquidity coexists with high inflation and rising rates.

Markets face pressure on both valuations and earnings. The 10-year government bond yield is already around 7.24% and could exceed 7.5% if inflation surprises upwards and rate increases continue. The Nifty 50’s valuation has fallen to about 19.1 times earnings despite strong domestic inflows, and a prolonged hiking phase could compress multiples further.

Corporate profitability faces rising input costs just as the benefit of last year’s cheaper borrowing begins to fade. Higher interest expenses would add to an earnings outlook that already looks flat. A higher growth forecast does not remove this combination of valuation compression and pressure on profits.

A retreat in oil and commodity prices, geopolitical de-escalation or a global recession could change the outlook, although these appear low-probability scenarios. Until then, the RBI’s own evidence points to a more difficult tightening cycle than its reassuring qualifications suggest. The rate hike acknowledges the problem; its diagnosis still understates the scale.
