What changed in petrol and diesel on March 23?

Bulk diesel for industrial buyers rose nearly 25% to ₹109.5 per litre, while HPCL increased premium petrol by ₹2 per litre. Regular petrol and retail diesel at pumps remain unchanged in most cities. The immediate pressure falls on factories and fleet operators that purchase institutional fuel.

Who pays the higher bulk diesel price now?

The higher rate applies to non-retail, institutional buyers such as factories, hotels, malls, mines, and large transporters that source diesel in bulk. Regular consumers filling at petrol pumps are not impacted by this hike, so the petrol diesel price today at retail outlets remains broadly steady.

Will this move raise inflation soon?

Near term CPI impact is limited if retail pump prices stay flat. The bigger risk is to WPI and core goods as higher diesel lifts manufacturing and freight inputs. If the spike persists, companies may pass costs to customers, which could slowly filter into consumer prices.

How can SMEs manage the diesel cost shock?

Update budgets with the new bulk diesel price, prioritize route optimization, tyre and engine upkeep, and driver productivity, and add indexed freight clauses. Compare compliant retail refueling with institutional procurement, and assess CNG or electric options for short-haul routes. Review pricing with customers more frequently.
