Discuss the effectiveness of targeted foreign exchange windows by the RBI in managing rupee volatility during oil-price shocks. What are the trade-offs for India's forex reserves?

India imports nearly 85% of its crude oil [2]. When oil prices rise, demand for dollars rises with them. On 10 October 2026 the RBI opened a special dollar window that meets the entire daily dollar need of IOCL, HPCL and BPCL, roughly US$300 million a day, through designated banks [1]. The window works well as a short-term shock absorber. However, it shifts the pressure onto the reserves rather than removing it.

Effectiveness in managing volatility

• Removes a large, predictable buyer from the spot market. SBI Research estimated that the window would take $250–300 million a day, about $75–80 billion a year, out of the market [3].
• Precedent of success: in April 2026 the rupee rose after the RBI barred OMCs from buying dollars in the spot market [4].
• Better market visibility: with oil demand separated out, genuine demand and supply are easier to read. This limits panic buying [3].

Limitations

• Treats the symptom, not the cause: the rupee has fallen about 6% since the West Asia conflict began [2], and the window does not change those fundamentals.
• Partial coverage: only PSU OMCs are included. Private refiners still carry the full currency risk [1].
• Exit risk: the window stays open "until further notice" [1]. When it closes, all of that demand comes back to the market at once.

Trade-offs for forex reserves

• Direct drain: at about $300 million a day, the window uses roughly $6–7 billion a month (indicative estimate).
• Already under strain: reserves fell about $51.1 billion from a record $785.7 billion to $734.6 billion (2 October) [5]. This included a record weekly fall of $18.3 billion [6].
• Borrowed cushion: part of the reserves came from FCNR(B) swaps. Those dollars must go back to banks when the deposits mature [7], so the RBI can freely use less than the headline figure.
• Still adequate: import cover is about 11 months [5], so the window is affordable in the short run.

Targeted windows calm volatility quickly, but the cost falls on the reserves. The RBI should set a clear exit trigger, as it did when it closed the FCNR(B) window early [8]. It should also publish how many dollars the window supplies and bring OMCs back to the market in stages. In the long run, less dependence on imported oil, in line with SDG-7, is the lasting protection for the rupee.
