Vertis Infrastructure Trust has announced that the National Highways Authority of India (NHAI) has reinstated the Wholesale Price Index (WPI) linking factor to 1.641 for the computation of user fee rates. This decision, effective from July 08, 2026, follows an Office Memorandum dated June 29, 2026, issued by the Ministry of Road Transport & Highways. The reinstatement ensures that the linking factor of 1.641 will continue to be followed for the revision of user fees under all existing contracts and concession agreements, including those held by the Trust's Special Purpose Vehicles (SPVs).
The development marks a reversal of the NHAI Circular dated September 13, 2025, which had initially revised the linking factor from 1.641 to 1.561. That earlier circular was subsequently kept in abeyance by an order from the Hon'ble High Court of Delhi dated October 17, 2025. The latest Policy Circular No. 18.127/2026 supersedes the September 2025 notification and directs that the 1.641 factor be adopted for all existing NHAI contracts until further orders are issued.
The Ministry of Road Transport & Highways, in its Office Memorandum, stated that the decision to maintain the 1.641 factor aims to preserve uniformity and consistency in implementation across projects. This guideline will also apply to all future National Highway projects pending any further amendments to the NH Fee Rules. The Trust confirmed that the information regarding this regulatory update has been uploaded to its official website.
The table below outlines the sequence of events regarding the WPI linking factor revision:
