RBI forex reserves in March 2026 have plunged $20 billion in three weeks. The rupee still hit a record low.
That’s the math the Reserve Bank of India is staring at. Since the Iran war began on February 28, the RBI has been selling dollars at a pace not seen since the 2013 taper tantrum — draining forex reserves from nearly $730 billion to $709.76 billion by March 13. The biggest weekly drop — $11.68 billion in a single week — was the largest since November 2024. And on March 20, the rupee crashed past 93 per dollar anyway, falling 108 paise in a single day. The steepest one-day drop in over four years.
Why RBI Forex Reserves Are Burning Fast
The RBI is fighting three fronts at once. Oil has peaked at $126 a barrel — and India imports 90% of its crude. Foreign investors have pulled $8 billion out of Indian equities in March alone. And the Gulf — India’s largest trading partner and source of over $50 billion in annual remittances — is now a war zone. The Qatar LNG strike blew a hole in India’s gas supply.
The central bank’s forward book tells the deeper story. The RBI has committed over $100 billion in forward dollar sales — obligations that don’t show up in the headline reserve number but will come due. Strip out gold, and India’s reserves now cover just 8.7 months of imports. The lowest in three years.
Standard Chartered says the RBI may stop defending if import cover drops to 9 months. It’s already knocking on the door.
The Question Nobody Wants to Answer
Goldman Sachs expects the rupee at 95 per dollar within a year. Emkay Global warns that if the war persists, 10-year yields hit 7% and corporate spreads surge. The current account deficit — previously estimated at 1% of GDP — could balloon to 2.5%. And fertilizer shortages are mounting just as kharif season approaches.
The RBI has options. Let the rupee depreciate faster — what Standard Chartered calls making the currency a “shock absorber.” Raise rates, though that kills growth. Or keep burning reserves and hope the war ends before the tank runs dry.
Here’s the thing about $709 billion in forex reserves: it sounds like a fortress. But at $20 billion a month, it’s a fortress with a clock on the wall. The rupee’s record low two weeks ago already felt like a floor giving way. The real question isn’t where the rupee lands — it’s when the RBI decides to stop catching it.
