Cube Highways Trust Secures Favorable WPI Linking Factor
NHAI confirms the WPI linking factor at 1.641, superseding a previous factor of 1.561.
Reader Takeaway: Regulatory stability achieved, confirming higher inflation-linked toll revenue growth for the Trust's assets.
What just happened
Cube Highways Trust announced that the National Highways Authority of India (NHAI) has officially retained the Wholesale Price Index (WPI) linking factor at 1.641. This decision, communicated via a Ministry of Road Transport & Highways (MoRTH) Office Memorandum dated June 29, 2026, and a subsequent NHAI circular on July 08, 2026, supersedes a prior directive from September 13, 2025, which had proposed a lower factor of 1.561 and faced legal challenges.
Why this matters
For Cube Highways Trust and its investors, this is a significant development. The WPI linking factor is crucial for revising user fees (tolls) on national highway projects. Maintaining the factor at 1.641 ensures that the Trust's revenue can continue to grow in line with inflation at a more favorable rate than the previously suggested 1.561. This removes a considerable regulatory uncertainty that had been impacting revenue projections.
The backstory
A previous directive in September 2025 had indicated a reduction in the WPI linking factor to 1.561. This proposed change created uncertainty for infrastructure trusts and developers whose revenues are often linked to inflation. The current update confirms the retention of the higher, more beneficial factor, resolving this ambiguity.
What changes now
The confirmation of the 1.641 factor means that the methodology for toll revisions remains supportive of inflation-indexed revenue growth for Cube Highways Trust's existing road assets. Furthermore, this revised policy will apply to all future National Highway projects, standardizing the approach across the sector.
Risks to watch
While this news resolves a specific regulatory overhang, investors should continue to monitor any future changes in government policy regarding toll revisions or the WPI series used for calculations. The long-term stability of such factors is subject to periodic review and potential policy shifts.
Peer comparison
This development directly benefits entities like Cube Highways Trust that rely on inflation-indexed toll revenues. Infrastructure Investment Trusts (InvITs) and companies with concessions for national highways will generally benefit from stable and predictable toll adjustment mechanisms.
