Sensex drops more than 540 points after the RBI's first hike in nearly four years

The Sensex fell more than 540 points to about 72,520 on Wednesday morning after the Reserve Bank of India raised the repo rate by 25 basis points to 5.50 percent and moved the stance to "calibrated tightening". The Nifty 50 lost about 176 points and slipped below 22,580. It was the first increase since February 2023, and the first session in which banks, finance companies, carmakers and property stocks had to price it.

The selling started before the decision. At 9.31 a.m., India Today had the Sensex at 72,670.99, down 396.82 points or 0.54 percent from an open of 72,965.38. The Nifty was at 22,625.15, down 148.70 points or 0.65 percent, after opening at 22,690.45. Titan was the heaviest Sensex loser at that hour, off about 3 percent. All major sector indices were in the red. The weakness followed two up sessions: the Nifty had gained 0.98 percent on Tuesday and the Sensex 0.95 percent, a bounce after the longest weekly losing run in 25 years.

The Monetary Policy Committee's vote was unanimous. The standing deposit facility rate is now 5.25 percent. The marginal standing facility and the Bank Rate are 5.75 percent. Governor Sanjay Malhotra's text dropped any near-term case for cuts and pointed to second-round effects from supply shocks. Traders who had treated a 25-point rise as already in the price were left with the stance. "Calibrated tightening" is the phrase that did the damage, because it tells lending desks not to build a cut into the next two meetings.

Rate-sensitive indices moved together. The Nifty Auto index fell more than 1 percent, with Maruti Suzuki, Tata Motors Passenger Vehicles, Mahindra and Mahindra, and Hyundai each down more than 1 percent. The Nifty Bank index slipped about 0.70 percent, close to 1 percent at the low. Non-bank lenders and realty stocks were in the same trade. Broader boards were mixed: the Nifty Midcap 100 was down, the Nifty Smallcap 100 was up. An early wire note said 30 Sensex stocks were in the red shortly after the announcement.

The mechanism is ordinary and worth spelling out because the hike is the first in nearly four years. A higher repo rate raises the cost of funds for banks at the margin. Floating-rate loans linked to the repo, which is how most retail and small-business credit is now priced, reset upward. EMIs on home and car loans lengthen or rise. Auto and property shares fall when dealers expect that reset to slow bookings. Bank shares fall when the market thinks deposit costs will rise faster than loan yields, which is the usual pattern in the first weeks of a hiking cycle. Wednesday's tape matched that pattern. It did not yet show whether the net interest margin hit is one quarter or three.

Foreign flows and crude were already leaning the wrong way before Malhotra spoke. Dealers cited continued portfolio outflows and firmer oil as the reason the open was weak even with the hike widely expected. The policy decision then removed the hope that the statement would be softer than the rate. A hike that is "priced in" still moves prices when the forward guidance is not. That is what the gap between the 9.31 a.m. print and the post-decision print records: about 150 further Sensex points, and a Nifty that went from 22,625 to under 22,580.

The level that matters for the rest of the week is not the morning low. It is whether Bank Nifty holds the loss after the governor's press remarks are digested, and whether the 10-year government bond cheapens enough to pull fresh selling into rate-sensitive stocks on Thursday. The RBI has put the repo at 5.50 percent and the stance at tightening. The market has put a first price on that combination. The EMI reset, which is what the auto and realty shares were discounting, arrives on the next due date of each linked loan, not on Wednesday's close.
