The short

  • Inflation: Core glidepath > headline noise. Data cue: watch services inflation stickiness.
  • FX & oil: USD/INR range + Brent sub-$80 = cushion for OMCs; sudden DXY spikes = risk-off trigger.
  • Flows: SIPs steady; FPI bias to banks/infra. Track block deals for rotation hints.
  • Equities: Leaders (PSU banks, cap goods) intact; breadth OK but pockets of froth in smallcaps.

Policy Watch: what RBI will weigh

  • Quality of disinflation: Core easing + stable wage growth = room to soften tone; food swings remain transitory unless second-round effects show up.
  • External matrix: If DXY > recent range or Brent > $82 for multiple sessions, expect tighter liquidity even with repo on hold.
  • Transmission & credit: Deposit repricing pace vs loan yields; rising deposit beta = pressure on NIMs → policy language stays cautious.

Playbook

Trader

  • Into prints: fade extremes; re-risk only on clean core downside surprise.
  • Pairs: Long PSU bank vs private bank on event days to dampen beta.
  • OMCs tactical longs if Brent < $80 and INR firm; tighten stops if DXY pops.

PM

  • Add on dips to domestic cyclicals with cash-flow visibility; avoid illiquid smallcap froth.
  • Balance with defensives into MPC; re-rotate on language upgrade (“further progress”).
  • Prefer names with positive OCF/EBITDA and stable leverage <= 2×.

Charts

  • CPI vs core vs Brent (12m): Visually separates noise from policy signal.
  • USD/INR with weekly reserve change: Proxy for RBI’s buffer into events.
  • Nifty breadth: % above 50-DMA/200-DMA; couple with A/D line for early fatigue.
