The short

  • Brent: ~$65.8/bbl this morning after rebounding from multi-month lows.
  • USD/INR: ~88.7–88.8; rangebound into global data.
  • Price actions: ATF up ~3.3% m/m (Oct 1 reset); commercial LPG +₹15.5/cyl; retail petrol/diesel unchanged.

Why Brent × INR matters for OMCs

Retail petrol/diesel marketing margins are driven by product cracks + Brent converted at USD/INR, net of duties, freight, and dealer commissions. Refining GRMs can offset weak marketing, but retail optics drive near-term P&L sentiment.

OMC margin sensitivity (illustrative)

Brent ($/bbl)USD/INRIllustrative retail marketing margin (₹/L)Read-through
6287.5+2.5 to +3.5Comfortable band; scope to hold prices
6688.5+1.0 to +2.0Base case near today’s setup
7089.0–0.5 to +0.5Margins tight; GRMs/discounting matter
7490.0–1.5 to –0.5Under-recovery risk unless retail bands move

Household fuel-bill planner (illustrative)

  • Two-wheeler city use: 500 km/month @ 45 km/L; a ₹1/L change ≈ ₹11/month.
  • Hatchback commute: 1,000 km/month @ 16 km/L; a ₹1/L change ≈ ₹62/month.
  • Small business (genset 10 L/week): a ₹1/L change ≈ ₹40/month.

Operator watch-list

  • Airlines: ATF +3.3% adds cost pressure; fare discipline and load factors key.
  • Hotels/Restaurants: commercial LPG +₹15.5; plan menu repricing cadence.
  • OMCs: Track Brent and USD/INR daily; balance refining vs marketing exposure; refine hedge tenors.

Near-term swing factors

  • Geopolitical news and sanction regimes affecting seaborne flows.
  • OPEC+ supply signals into November.
  • US inventory prints and global demand indicators.
