Petrodollar

The petrodollar is less a physical thing than an arrangement: for decades, oil has been priced and settled in US dollars, so every nation that imports crude must first acquire dollars, and every exporter accumulates them. Those surplus dollars get 'recycled' back into US Treasuries, global banks and markets. The question the term really answers: why has the dollar stayed the world's dominant currency, and what happens to a big oil importer like India when that system shifts?

Why this matters for India

India imports the overwhelming majority of the crude it consumes, which makes it structurally dependent on dollars. Every barrel historically meant buying dollars, putting steady pressure on the rupee and on forex reserves. When oil spikes, the import bill swells, the trade deficit widens, and the rupee tends to weaken — one reason an oil shock feeds directly into India's inflation worries.

The system is fraying at the edges

The petrodollar's grip is loosening, and India is part of the story. After Western sanctions on Russia, India became one of the biggest buyers of discounted Russian crude — at one point a large share of its imports — and began settling some of those purchases in rupees and, increasingly, other non-dollar currencies rather than dollars. The RBI has also pushed state refiners to get Gulf suppliers to accept a slice of payments in rupees. India even made early rupee payments for UAE crude.

This is part of a broader, slow 'de-dollarisation' trend. It is not the end of the dollar — most global oil still trades in it — but the monopoly is no longer absolute.

The bigger picture

For an Indian investor, the petrodollar story connects oil prices, the rupee and the broader currency landscape. A weaker dollar regime could ease India's import burden over time, while a strong dollar squeezes it. Moves toward rupee-settled trade aim to cut that dependence and the currency-conversion costs that come with it. The honest view: de-dollarisation is real but gradual, and the dollar's reserve role will not vanish quickly — though India clearly wants its own currency to count for more.
