India's private sector business activity slowed to over a three-year low in March 2026, as the escalating US-Israel war with Iran weighed heavily on new orders and domestic demand. The HSBC India Composite PMI showed the sharpest slowdown in recent memory, with new orders rising at their slowest pace in more than three years. Goldman Sachs has cut India's 2026 GDP forecast to 5.9%, down from a pre-war forecast of 7%, marking the bank's second downgrade in less than two weeks. Goldman now expects the near-shutdown of flows through the Strait of Hormuz to extend into mid-April, with Brent crude averaging $105 per barrel in March and $115 in April — described as the largest disruption to energy supply since the 1970s energy crisis. The rupee has fallen 4% against the US dollar in 2026 so far, and Goldman analysts now see India's 2026 inflation rising to 4.6%, up from an earlier expectation of 3.9%. Goldman expects a 50 basis point hike in the policy repo rate. Direct tax collection for FY26 as of March 17 grew 7.19% to ₹22.80 trillion, driven by higher corporate and non-corporate taxes.
