WPI Base Revision & the Move to PPI
India's wholesale-price architecture has been rebuilt. Since 15 June 2026 the Wholesale Price Index runs on a 2022-23 base with a wider 957-item basket; the 14 July bulletin printed June inflation of 9.87% next to two new producer-price gauges, an Output PPI and a trial Input PPI. On 20 July the Index of Core Industries was rebased to 2022-23 as well, adding iron ore as a ninth core industry. The quarterly Service PPI, the third leg of the new producer-price family, printed its first quarter of FY 2026-27 on 24 August 2026: air passenger fares led at 126.4, pension-fund management jumped to 113.3 and telecom held at 112.2. All of it sits inside a broad statistical refresh: a five-year WPI-to-PPI transition, MoSPI's first trial Index of Services Production, and the Labour Bureau's rebasing of the labourers' consumer-price indices.

- India's Maritime & Shipping ReformsAdds the National Shipping Board's first Sagar Samvad, held in Delhi on 25 August 2026, and the fleet numbers it put on record: India pays close to $75 billion a year in freight to foreign shipping lines for its crude, gas, coal and urea; an Indian-flagged ship costs 16 to 20 percent more to run than a foreign one; and the board's five-point roadmap — fiscal reform, assured cargo, competitive finance, lighter regulation, ease of doing business — aims to add 100 ships in five years. Also records the NSB's origins (1958, reconstituted May 2025 under Sameer Kumar Khare, now anchored in the Merchant Shipping Act 2025), its new website, the ₹10,000 crore Container Manufacturing Assistance Scheme and the 10,000 million tonnes port-capacity goal for 2047. The stat strip now carries the freight bill and the fleet goal; the EXIM share and dredger count stay in the prose and pointers.
