INR Record Low Redistribution

Wednesday at the desk. USD INR printed 95.85 today. Fresh record. Brent held above 105 for the third session running. Two screens away the Pharma index was green, Cipla up 8 percent on Q4. The IT index was red, HCL and Tech Mahindra at the bottom of the table.

Same currency print. Two opposite tapes.

Every WhatsApp group I am on woke up to a version of the same line. Rupee weak therefore portfolio bad. The actual screen disagreed in two opposite directions on the same day. That is the whole lesson.

The rupee is not a top of P&L event. It is a line item event.

Three buckets on the same index.

Revenue line exporters. TCS, Infosys, HCL Tech, Wipro, Cipla, Sun Pharma, Dr Reddys. Earn in dollars. Spend in rupees. A weaker rupee means more INR per dollar billed without lifting a finger. The industry rule of thumb is roughly plus 30 to 40 basis points of EBITDA per 1 percent INR depreciation, more for the pure exporters.

Cost line importers. BPCL, HPCL, IOC, IndiGo, Asian Paints, MRF, Apollo Tyres. Inputs priced in dollars. Pricing power lags. A weaker rupee shows up in the cost of goods sold line inside the same quarter. Roughly minus 40 to 60 basis points the other way.

Neutral core. HDFC Bank, ICICI Bank, HUL, Nestle, HDFC Life. Earn in rupees. Spend in rupees. The currency does not show up on either line.

One catch worth saying out loud. The OMC retail block sits in the importer bucket on the input side, but marketing margins compress when crude rallies and the rupee weakens together because pump prices do not adjust fast enough. The OMC line is a counter trade on Brent and INR, not a clean energy bet.

Three rules I keep coming back to. The cost line moves before the revenue line. A weak rupee against the dollar alone is messier than a broad weakness, watch DXY as much as USD INR. And write down the dollar revenue share and the dollar cost share of every holding before reading the next FX headline. The spread between those two is the number that matters.

The portfolio that quietly loves a weak rupee earns in dollars and spends in rupees. The portfolio that quietly hates it is the one filling its tank
