The short
- Timings: ATF prices typically reset on the 1st and 16th each month; LPG (domestic/commercial) generally resets on the 1st.
 - Who’s sensitive: Airlines (fuel share high), OMCs (marketing/refining), restaurants/hospitality (commercial LPG), and logistics.
 - What to track: Brent trend, INR path, and any OMC pricing actions through the week.
 
Airlines & travel
- Every 1% ATF change can ripple through yields and load-factor strategy in peak months.
 - Hedge by rebalancing fare buckets and monitoring competitor promo windows.
 
OMCs & fuel retail
- Watch marketing margins vs refining GRMs; Brent + INR is the two-variable matrix.
 - Balanced OMCs (refining + marketing) tend to cushion short-term shocks better.
 
Restaurants, hotels & SMEs
- Commercial LPG resets feed directly into COGS; stagger procurement and check vendor bands.
 - Update menu-engineering weekly if volatility persists.

| Input | Assumption | Impact cue | 
|---|---|---|
| Brent | +2–3% WoW | ATF ↑; check airline yield actions in 24–48h | 
| USD/INR | ±0.5 | Imported input pressure; OMC margin sensitivity | 
| Commercial LPG | ±₹25–50/cylinder | Hospitality/SME COGS; consider pass-through bands | 
Checklist for operators
- Set alerts for OMC circulars before market open on Oct 1.
 - Pre-approve fare/menu adjustments within guardrails; communicate early to customers.
 - Lock logistics SLAs for the week; add fuel-surcharge clauses if needed.
