THE IMPORT DEPENDENCE
India imports roughly 85% of its crude oil — the highest dependence among major economies. Every $10/barrel rise adds about $15 billion to the annual import bill, draining dollars from reserves and pressuring the rupee.
THE TRANSMISSION CHAIN
Oil shock to equity rout follows a predictable path: dearer crude widens the current account deficit, weakens the rupee, scares foreign portfolio investors out of Indian equities, and forces the RBI to defend the currency by selling dollars or hiking rates.
THE FII REFLEX
Foreign institutional investors hold roughly a fifth of Indian listed equities — far more than domestic mutual funds at the margin. When the rupee slips, their dollar returns shrink even if Sensex holds, so they sell first and ask questions later. This is why Indian equities track the rupee more tightly than fundamentals justify.
THE RUPEE'S LONG SLIDE
The rupee has depreciated against the dollar in nearly every year since liberalization in 1991, when it traded near 25. The RBI's stated policy is to smooth volatility, not defend a level — but in practice every crisis triggers heavy intervention from the country's ~$650bn reserves.
WHY RBI'S HANDS ARE TIED
The RBI faces a classic trilemma: it cannot simultaneously hold the rupee stable, keep capital flowing freely, and run independent monetary policy. Hiking rates to defend the rupee chokes growth; cutting to support growth accelerates outflows. The April CPI print will tip which side dominates the next meeting.
THE HORMUZ MULTIPLIER
India sources roughly 40% of its crude from the Persian Gulf, virtually all of it transiting the Strait of Hormuz. Unlike China, India lacks strategic petroleum reserves at meaningful scale — its SPR holds about 10 days of imports versus China's 90+. A prolonged closure would force rationing within weeks.
