New Delhi: India's CPI inflation is expected to rise by around 70 bps to 4.8 per cent with crude oil averaging USD 90/bbl in FY27, according to a report by 360 ONE Capital. This projection comes as the ongoing conflict in West Asia and a downgraded domestic monsoon forecast introduce fresh challenges to India's macroeconomic trajectory.The report noted that the conflict in West Asia and the resulting energy supply disruptions warrant a reassessment of key macroeconomic assumptions. "Our revised base case assumes de-escalation by mid-June, with crude oil averaging USD 90/bbl in FY27. Under this scenario, CPI inflation is expected to rise by around 70 bps to 4.8% (from 4.1%), while GDP growth moderates to 6.3% (from 6.7%). The fiscal deficit is projected to widen to 4.6% of GDP (from 4.4%), and the current account deficit to 2.1% of GDP (from 1.3%)," the report stated.Also read: India meets FY26 fiscal deficit goal at 4.4% of GDP despite revenue and global pressuresThe report noted that India's economic momentum remains stable due to domestic consumption and public spending, but geopolitical frictions pose tangible downside risks. Supply routes through the Strait of Hormuz are particularly vital, as India sources nearly 50 per cent of its LPG and around 30 per cent of its natural gas requirements through this route.Even though the "net petroleum import bill has declined from 5.5% of GDP in FY14 to around 3.0% in FY25, the economy remains exposed to a prolonged disruption in energy supplies."On the monetary front, global financial conditions continue to tighten as central banks react to persistent inflationary impulses. While the Reserve Bank of India is expected to keep policy rates unchanged in the upcoming meeting, domestic bond yields face upward pressure from a widening fiscal deficit and higher energy costs.Also read: Manufacturing activity at 3-month high in May despite cost woesThe report mentioned that the impact on macroeconomic variables is likely to be non-linear, implying significantly larger downside risks if the conflict persists. "A further USD 10/bbl increase in crude prices above our base assumption could push inflation to 5.6% (assuming a partial pass-through of around 5% to retail fuel prices), lower GDP growth by an additional 40 bps to 5.9%, widen the current account deficit to 2.5% GDP, and increase the fiscal deficit to 4.8% of GDP," the report added.Compounding these external geopolitical risks, the domestic agricultural outlook faces unexpected pressure. In its Second Long Range Forecast, the IMD downgraded the Southwest Monsoon 2026 forecast to 90 per cent of the Long Period Average (LPA) from 92 per cent estimated in April.This development represents the weakest monsoon outlook since 2015, which raises immediate concerns over overall agricultural output and rural demand.In the global perspective, the IMF has lowered its 2026 global growth forecast by 20 bps, citing risks from the Middle East conflict through higher commodity prices, inflation, and tighter financial conditions.The report stated that under the IMF's reference scenario, "global growth is projected at 3.1% in 2026 and 3.2% in 2027, below both the recent 3.4% pace and the historical average of 3.7%. In adverse scenarios, growth could slow to 2.5% or even 2.0%, accompanied by significantly higher inflation, with emerging markets expected to be disproportionately affected."
