In this piece:
  • Base case on rates & stance
  • Cut triggers vs. inflation triggers
  • Market implications: STCI, duration, PSU banks
  • Watchlist into Sep 29–Oct 1

The short

  • Calendar: Next MPC on Sep 29–Oct 1, 2025.
  • Setup: Growth surprise (Q1 FY26 at 7.8% YoY) vs. easing core CPI; food path & tariffs are swing risks.
  • House view (illustrative): Base-case hold with a dovish tilt; shallow cut cycle contingent on food normalization & stable FX.

Cut path vs. inflation path

When cuts come

  • Core CPI grinding lower; headline moderated if food fades post-monsoon.
  • External: benign USD backdrop, contained oil band.
  • Transmission: lending rate passthrough steady; output gap narrowing but not closed.

When cuts pause

  • Food shocks persist; reservoir deficits → sticky headline.
  • Tariff spillovers push tradables inflation and dent exports.
  • FX volatility or imported inflation re-widening the real policy gap.

Portfolio Plan

BucketWhat to watchPositioning lens
STCI (up to 3y)Overnight/3M bill rates; VRR/VRRR cadenceCarry+roll still attractive; add on dips
Duration (7–14y)Term premium vs. history; auction tailsPrefer staggered adds; convexity wins if path to cuts clears
PSU BanksCredit growth, cost of funds, LDRBenefit from curve bull-steepening; watch HTM/AFS mark-to-market
NBFCsNIM resilience; securitization costsSpread sensitivity to policy signalling & liquidity

Data watch into the meeting

  • Inflation High-frequency food; core momentum.
  • Growth PMI breadth, credit growth, e-way bills.
  • External Oil band, FX stability, export orders.
  • Liquidity System surplus/deficit, CD/CP prints.
Reading guide: A hold with dovish language keeps carry trades supported; a clear cut-cue extends duration outperformance and favors quality PSU bank exposure.
