RBI swap window: Public sector undertakings are preparing to tap overseas debt markets even as the rupee remains under pressure. State-owned enterprises are expected to raise more than $15 billion through external commercial borrowings in FY27, against their usual annual overseas borrowing of $10-12 billion.
The trigger is a special Reserve Bank of India window that allows select PSUs to raise dollar debt abroad and convert the proceeds into rupees through a concessional foreign exchange swap. The facility is open until September 30, 2026. Its purpose is direct: bring in foreign currency, lower funding costs for large state-owned borrowers, and reduce pressure on domestic debt markets.

India needs capital inflows to finance infrastructure and support external stability. The rupee, meanwhile, has faced depreciation pressure from global uncertainty, high US interest rates and periodic outflows from emerging markets. The RBI’s swap facility addresses both concerns. It brings in dollar flows while giving large public enterprises cheaper rupee funding.
RBI swap window cuts borrowing cost
PSUs such as NTPC, Power Finance Corporation, REC, Indian Oil, Exim Bank and NaBFID need long-term money for power plants, transmission lines, roads, ports, logistics corridors and urban infrastructure. They can borrow in rupees at home or raise dollar loans abroad through external commercial borrowings. The second route usually carries currency risk.
That risk is the obstacle the RBI has chosen to soften. The concessional swap facility lets PSUs raise dollar-denominated debt overseas and swap it into rupees at a subsidised cost. For borrowers, the dollar interest rate is only the first number. Once exchange-rate risk is hedged, the effective cost can rise sharply. The RBI window lowers that burden.
The estimated advantage is close to 3 percentage points over domestic borrowing. For infrastructure-heavy PSUs, this is not a marginal saving. On large, long-gestation projects, it can mean hundreds of crores of rupees over the life of the loan.
The RBI used a similar foreign exchange swap window during the 2013 taper tantrum, when fears of US monetary tightening triggered capital outflows from emerging markets and put the rupee under stress. Then, too, the aim was to attract foreign currency and stabilise the exchange rate.

PSU debt can ease domestic markets
This time, the objective is wider. The RBI and the government are also trying to revive non-bank funding channels. Foreign direct investment inflows have been weak. Corporate bond issuance has moderated. ECB flows have slowed. According to SBI Research, ECB and foreign currency convertible bond inflows fell nearly 30% in FY26, from $61.2 billion to $42.9 billion.
The swap window is also part of a wider rupee-defence package. The RBI and the government are trying to pull in dollar flows through several channels, not just PSU borrowing. These include support for foreign currency non-resident bank deposits, easier access for foreign investors to Indian debt, and tighter timelines for export proceeds. That context matters. The PSU window is not merely a cheaper funding line for state enterprises. It is a balance-of-payments instrument.
PSU borrowing can partly fill that gap. Large government-backed entities have better access to global debt markets than most private borrowers. Their strategic role and implicit sovereign support make them acceptable to international investors.
Overseas borrowing looks attractive despite elevated global interest rates because the RBI swap window changes the effective cost. Several PSUs may front-load borrowing plans that would otherwise have been spread over later years. Some may raise funds for projects still at the planning stage. That is normal when a temporary policy window creates a funding advantage. Treasury teams will move before the September deadline.
There is a domestic gain as well. If large PSUs shift part of their borrowing overseas, they will reduce demand for funds in the Indian bond market. That can create space for private borrowers and ease pressure on corporate bond yields. SBI Research has argued that this could reduce crowding-out and improve transmission of monetary easing.

Infrastructure gains, currency risks remain
The government’s interest is clear. Infrastructure remains central to growth. Power generation, transmission networks, railways, logistics corridors, renewable energy and urban infrastructure all need large capital outlays. Much of this burden sits with state-owned enterprises. Cheaper funding can improve project viability and speed up execution without adding directly to budgetary pressure.
The gains are real, but they are not risk-free. Foreign currency borrowing exposes emerging-market borrowers to exchange-rate volatility. Hedging reduces that risk, but does not abolish it. Large external liabilities can become a problem if market conditions shift, hedging costs rise, or the rupee weakens for a sustained period.
This is the familiar danger in all foreign borrowing booms. Cheap money abroad can look irresistible until the currency moves the wrong way. The RBI’s window is a useful instrument, not a substitute for prudence.
There is another risk. A temporary window can bunch borrowing decisions. If PSUs front-load 3-5 year ECBs before September 2026, repayment and refinancing pressures could also bunch later. That would matter if global rates rise, credit spreads widen, or the rupee weakens. Implicit sovereign comfort helps PSUs raise money abroad. It should not become a substitute for project discipline.
For now, the central bank has given PSUs a rare chance to borrow abroad at a discount. If the response matches expectations, FY27 could become one of the biggest years for PSU external fundraising in recent memory. That would help infrastructure investment. It would also add another test of how well India manages foreign capital when the rupee is under strain.
