Small Industries Development Bank of India and Sagarmala Finance pulled ₹6,600 crore of bond sales in five days rather than pay what investors asked, as the government's one-year borrowing cost reached 6.18%, the highest since 2 April 2025.

SIDBI wanted to pay no more than 7.90% for three years and was asked about 7.97%; Sagarmala, a state-owned maritime lender, wanted less than 8% for ten years and was bid as much as 8.44%, Business Standard and the Economic Times reported. Reliance Industries and a unit of Adani Enterprises went ahead.

The Reserve Bank of India's six-member Monetary Policy Committee meets from 5 to 7 October. It has held its rate at 5.25% for four meetings after cutting it by 1.25 percentage points in 2025, and last raised it in February 2023, Business Standard noted. The government's one-year cost, set at the weekly Treasury-bill auction on 30 September, is 0.93 point above that rate and 0.57 point above its level a year ago.

For a company the price of new money matters in proportion to what it must raise; filings show the finance costs already booked. The 1,021 listed companies whose results can be compared booked ₹3.44 lakh crore of interest in the four quarters to June against ₹3.43 lakh crore a year earlier, according to Kiwaro's calculations from their filings. A year of rate cuts left the bill where it was. Operating profit grew 10%, so interest took 19.5% of it, down from 21.4%.

The interest bill rose at several large borrowers. Power companies' interest rose 14% to ₹52,878 crore and took 38% of their operating profit, up from 35%. JSW Energy's nearly doubled to ₹6,030 crore, Adani Green Energy's rose 34% and Adani Enterprises' 26%. Adani Airport Holdings, which paid 8.96% this week, is a unit of Adani Enterprises.

Every listed company outside finance with interest above ₹5,000 crore, except Mahindra & Mahindra (₹9,720 crore), whose accounts include a lending arm.

Across all 1,078 companies with a full year of results, interest was ₹3,50,188 crore, 19.4% of operating profit. At 110 of them it took more than half; on the comparable set that count fell to 105 from 122. Below the table's line, GMR Airports' interest was 83% of operating profit and Hindustan Petroleum's twice its operating profit, against a fifth a year earlier. Fifty-four companies had no operating profit to set against ₹29,257 crore of interest: Vodafone Idea, Mahanagar Telephone Nigam with ₹2,976 crore, and smaller bills at Shree Renuka Sugars, Alok Industries and Aditya Birla Fashion and Retail.

Every industry with interest above ₹5,000 crore, among the 472 companies Kiwaro has classified by industry. The year-earlier column covers the companies with results for both years.

The heaviest borrowers are also the main customers of a few industries. Power plants take 54% of the coal sold to industry and steel mills 28%, and almost all iron ore goes to steel, according to India's official supply-use tables for 2023-24, which record what each industry buys from every other.

Bank loans have not followed the bond market. State Bank of India's one-year loan benchmark has stood at 8.70% since December, its published rates show. The median across banks was 8.61% in September, according to the RBI: lower than August's 8.70% and level with 8.60% a year earlier. Under RBI rules banks review those benchmarks every month against their own cost of funds.

Bond dealers point abroad and to oil. "The 10-year US Treasury yield rose beyond 5.30 per cent, while Brent crude climbed above $100 a barrel which led to selling of bonds," a dealer at a primary dealership told Business Standard on 1 October. The US Treasury's own daily rate for 10-year debt was 5.24% that day, 1.12 percentage points above a year earlier, and Brent in dollars is about 60% dearer than a year ago. Supply is the other weight, the Economic Times reported: the government plans to sell ₹7.86 lakh crore of bonds between October and March, and the RBI has sold a net ₹1 lakh crore this financial year, the most in more than a decade, Mint reported, citing Reuters. India's benchmark 10-year yield closed at 7.21% on 1 October, the highest since April 2024, according to Business Standard.

Still, cash is not scarce, and how much of the bill resets cannot be read from filings. Banks held a surplus of ₹4.85 lakh crore with the RBI on 30 September, six times the level of a year earlier, though down from the record ₹11.16 lakh crore in early September that the Economic Times reported; they lent to each other overnight at 5.22%, below the policy rate. Filings give the interest booked, not the debt behind it or its terms: finance costs include interest on leased aircraft, towers and shops, on spectrum bought in instalments and on foreign-currency debt, little of which moves with an Indian benchmark, and fixed-rate bonds change cost only when they are refinanced.

Data note: Interest is finance costs as filed, an expense booked rather than cash paid, on group accounts where a company files them; operating profit is total income less total expenses, plus finance costs. Banks and other lenders are not counted, and the year-earlier comparison uses the 1,021 companies with both years on the same basis. Not netted out: listed subsidiaries counted again inside listed parents (about ₹10,800 crore in the eleven pairs we can name) and the 606 smaller companies not yet classified by industry, which carry 17% of the interest and are missing from the industry table.
