RBI's Reserves Strategy Caps Rupee Value

Cheaper crude, capped rupee: RBI's reserves grab overrides the oil dividend

Eight economists tell Mint the rupee stays boxed at 94–96/USD through March 2027 — the RBI is banking the oil windfall as reserves, not letting it lift the spot rate.

Brent crude has crashed roughly $42 a barrel from its May peak, the US–Iran war is over, and India's rupee still cannot break out. Eight economists polled by Mint on July 7, 2026 kept their forecasts intact: 94–96 per dollar in the near term, drifting to 96.5 by March 2027. The reason is not oil. It is the Reserve Bank of India's decision to absorb almost every incoming dollar into its FX reserves rather than let them clear in the spot market — a deliberate policy choice that converts a terms-of-trade windfall into balance-sheet cushion, and leaves exporters, not importers, as the intended beneficiaries. That is the story here, and it reframes every headline about "relief" from cheaper oil.

The oil dividend that never reached the exchange rate

The war on Iran that began on February 28, 2026 sent Brent from $72.87 the day before to $105.45 by mid-May and briefly $114 a barrel, according to prices tracked by Al Jazeera and Bloomberg data cited in the Mint poll. India, which imports about 90% of its crude, watched the rupee slide more than 3% in the same window to a record 96.82 on May 20, capping an 11% depreciation across fiscal 2026. The Strait of Hormuz — 55% of India's crude, 60% of natural gas and 90% of LPG normally transit it — was disrupted for weeks, per reporting by the BBC.

Then, on June 17, a US–Iran memorandum of understanding effectively ended the shooting phase. Brent collapsed toward $72. The textbook response for a large oil importer would be a sharp rupee rally: import bill down, current-account math improves, dollar demand falls. It did not happen. The rupee closed 95.4 on July 6, according to Mint, well off its low but nowhere near a re-rating.

The disconnect is deliberate. As Madan Sabnavis, chief economist at Bank of Baroda, told Mint, the current 94.5–95.5 band "has effectively become its new equilibrium" — and the RBI's June 5 measures on Foreign Currency Non-Resident (FCNR) deposits "would not materially increase the supply of dollars in the domestic market as the incoming dollars would be exchanged with RBI and kept as reserves."

The RBI's plumbing: swap window, FCNR sweeteners, and a $107 billion forward book

On June 5, 2026, the RBI announced a package to draw dollars in without letting them push the rupee up: it agreed to bear the hedging cost of FCNR deposits for banks and eased external commercial borrowing rules for public sector companies and banks, according to the Financial Times index of RBI coverage. The central bank also opened a dollar–rupee swap window explicitly to route flows through its own balance sheet rather than the spot market, per Mint's linked coverage.

Gaura Sengupta, chief economist at IDFC First Bank, told the same Mint poll that "RBI's reserve management will tend to be towards building FX reserves" — with about $107 billion of outstanding buy–sell swaps and more than $100 billion maturing over the next two years, the incoming FCNR dollars are earmarked to replace maturing forward positions, not to enter the market.

That is the mechanical explanation for a paradox. India's reserves have fallen $61.6 billion since February to $666.9 billion as of June 26, 2026, per RBI data cited by Mint. The IMF's 2025 Article IV report had already pushed New Delhi in the opposite direction: "India is well positioned to allow greater exchange rate flexibility… FX intervention should be used only when large shocks cause disruptions in liquidity conditions." The Fund noted that as of October 2025, reserves at $695 billion already covered 109% of the IMF's reserve adequacy metric and over eight months of prospective imports. In other words, the RBI is running a heavier managed-float regime than the IMF thinks is optimal — and July's poll confirms it plans to keep doing so.

The deeper problem: the rupee's weakness is not about oil

The uncomfortable second-order point in the Mint data is that removing the war shock did not restore the currency. That fits a diagnosis The Economist made in April, before the ceasefire: "India's weak currency reflects deeper problems than the Iran war… a persistent inability to draw in foreign investors." Foreign portfolio investors have pulled $14.77 billion out of Indian equities so far this fiscal year, offset only partly by $5.54 billion of debt inflows, per National Securities Depository Limited data cited in the poll.

The BBC, drawing on Nomura and India's chief economic adviser V. Anantha Nageswaran, reports that India's balance of payments gap has crossed $70 billion and the fiscal deficit is projected to widen to 4.6% of GDP by March 2027, above the 4.3% budget target. Net FDI has stagnated. That is why Upasana Bharadwaj, chief economist at Kotak Mahindra Bank, told Mint the RBI's June measures "have largely eliminated the worst-case scenario for the currency without changing its longer-term trajectory" — they "capped the upside" as well as the downside. Bernstein's worst case, quoted by the BBC, had put the rupee beyond 110 to the dollar in a prolonged war; the RBI's swap plumbing pulled that tail risk off the table, but nothing has arrived to pull the fair-value estimate back below 94.

The IMF's 2025 Article IV report is blunt on the mechanism: "FX intervention should promptly be sterilized to avoid unintended liquidity fluctuations and preserve monetary policy transmission." That is exactly what the RBI is doing — sterilising inflows into reserves — and the direct cost is a rupee that cannot use the crude relief.

Who wins and who loses from the managed peg

The winners are exporters — IT services, textiles, engineering goods — whose dollar receipts translate into more rupees at 95.4 than they did at 88. The losers are: importers of oil, fertiliser, gold and electronics, whose input costs stay elevated; Indian consumers, who absorbed a 3% petrol and diesel price hike in mid-May, the first in four years, according to Al Jazeera; and foreign portfolio investors sitting on rupee losses, who now face a currency whose upside is being administratively capped.

The political calculus behind that ranking is not opaque. As Aurodeep Nandi and Sonal Varma of Nomura noted, cited by the BBC, a slide toward 100 rupees to the dollar would become "a potent symbol of economic weakness." New Delhi is willing to spend reserves to prevent that number. It is not willing to spend political capital telling the electorate that a stronger rupee — which would make imported oil, gold and iPhones cheaper — is a legitimate use of the same dollars. Choosing reserve accumulation over consumer relief is a choice; the poll makes it visible.

There is also a structural bet embedded in the RBI's plumbing. India's chances of inclusion in the Bloomberg Global Aggregate Bond Index have improved after the government removed withholding tax and capital gains tax on eligible government securities, Mint reports; JPMorgan's index inclusion, reported by the FT in 2024, already brought an estimated $41 billion in tracked flows. If Bloomberg's Global Aggregate follows — an index tracked by roughly $60 trillion in AUM, per an IMF working paper — the RBI wants headroom on its balance sheet to absorb the surge without a disorderly appreciation that hurts exporters. The June 5 package and the swap window are the pre-positioning for that flow, not a response to the Iran war.

Diplomat View

The Mint poll is not a forecast of the rupee. It is a readout of a policy regime. Governor Sanjay Malhotra's RBI has decided that the rupee's fair value sits at 95, that the balance-sheet cost of holding it there is acceptable, and that the political cost of letting it rally is not. The oil dividend from the US–Iran ceasefire is being converted into foreign-exchange reserves and forward-book unwinds, not into consumer purchasing power. That is the trade — and it will hold unless one of three things breaks it.

Our call: the rupee finishes March 2027 in a 95–96.5 band, closer to 96 than 95, with the RBI adding $30–50 billion to reserves over the next nine months via FCNR and ECB channels. We would revise if: (a) Brent sustains above $85 for a quarter, forcing renewed reserve drawdowns; (b) US tariff escalation triggers a fresh $10 billion-plus equity outflow, breaking the 96.5 anchor; or (c) Bloomberg index inclusion is confirmed on an accelerated timeline, in which case the flow overwhelms sterilisation capacity and the rupee tests 93. Absent those, the "cheaper crude equals stronger rupee" trade is dead on arrival — the policy function has decoupled them.

What to watch next

• August 2026 RBI monetary policy meeting. Any sterilisation-related language on liquidity absorption or CRR will confirm the reserves-first posture flagged by the IMF Article IV.
• Bloomberg index inclusion decision, expected in H2 2026. A green light would test whether the RBI can absorb passive inflows without letting the rupee break 94.
• India's Q1 FY27 current-account data (September release). If the trade balance narrowing from cheaper crude does not translate to a smaller CAD, it will confirm that gold, electronics and services-import demand is filling the gap.

The bottom line: Cheaper oil no longer lifts the rupee because the RBI has decided it should not — the central bank is converting the post-war windfall into reserves and forward-book cover ahead of expected bond-index inflows, and eight economists surveyed by Mint say that policy, not crude, sets the exchange rate through March 2027. The rupee's new equilibrium is a political choice dressed as a market outcome.
