RBI’s 1.5% concessional forex swap facility, backed by a landmark February 2026 ECB overhaul, has opened the cheapest overseas borrowing window for PSUs in years. Here’s what the numbers say, who benefits, and what equity investors should track right now.
Key Takeaways
- RBI Governor Sanjay Malhotra announced the forex swap on June 5; RBI circulars issued June 8 operationalised the facility.
- Fixed swap rate: 1.5% per annum, compounded semi-annually. The Window is open until September 30, 2026.
- All-in ECB cost for top-rated PSUs: ~6.1%–6.6%, versus 7.30%–7.50% in domestic bond markets, a saving of up to 140 bps.
- Barclays estimates $10–15 billion ECB uptake from PSUs. SBI Research’s Ecowrap report estimates ECB and OFCB swap windows could garner $15–20 billion in FY27.
- The February 2026 ECB amendment, removing cost ceilings, raising limits to $1 billion, is the structural foundation under the swap story.
- India’s forex reserves as confirmed by RBI Governor Malhotra stand at $682.3 billion, adequate to cover 11 months of imports.

What Triggered This Move
The rupee has been under severe and documented pressure. The rupee depreciated 4.9% in full-year 2025, breaching the ₹90-per-dollar mark in December, after beginning that year at nearly ₹85.6. In the first five months of 2026 alone, depreciation reached 7.04%, already surpassing the full-year rates of both 2025 and 2024. After falling to an all-time low of 96.82 on May 20, the rupee recovered to 96.20 after the RBI intervened via state-run bank dollar sales.
The all-time peak for forex reserves was $728.49 billion, hit on February 27. Consecutive drops following the West Asia conflict dragged holdings down to $681.38 billion by May 22 before recovering to the current $682.3 billion level.
The RBI’s response: revive a crisis-era tool. According to SBI Research’s Ecowrap report, the February and June 2026 measures should be viewed as a coordinated attempt to stabilise the rupee, deepen the domestic debt market, attract more stable foreign capital, and reduce friction for external funding, with the February measures being structural and market development-oriented, while the June measures aimed to attract foreign currency inflows without raising domestic interest rates.
How the Swap Facility Works
The ECB swap covers borrowings with an average maturity of three years or more raised by PSUs, and Overseas Foreign Currency Borrowings raised by authorised dealer banks with a minimum three-year maturity. The swap transaction with the RBI is conducted in US dollars regardless of the ECB’s original currency. Maximum swap tenor is capped at five years, aligned with the loan’s repayment schedule.
| Step | Transaction |
|---|---|
| 1 | PSU raises dollar loan or bond overseas |
| 2 | Arranging bank sells dollars to RBI |
| 3 | RBI provides rupees to the bank |
| 4 | Fixed swap premium of 1.5% p.a. (compounded semi-annually) locked in |
| 5 | At maturity, rupees + premium returned to RBI; dollars reclaimed |
| 6 | Borrower gains fully predictable hedging cost for the entire tenure |
The facility operates daily on working days. Banks can swap an amount equivalent to eligible ECB or OFCB inflows received during the preceding weeks.
The Cost Math: Why 7% Is the Viability Line
SOFR stands at 3.63% as of June 8, 2026. Adding the RBI’s 1.5% swap rate and a 1% bank spread, a top-rated PSU arrives at an all-in cost of ~6.13%–6.63% for a three-year overseas loan, below the 7.30%–7.50% these same entities pay in the domestic bond market.
| Component | Rate |
|---|---|
| SOFR (as of June 8, 2026) | 3.63% |
| RBI Fixed Swap Rate | 1.50% |
| Bank Spread (market estimate) | ~1.00% |
| All-in ECB Cost (estimated) | ~6.13%–6.63% |
| Domestic Bond Market Rate (AAA PSU) | 7.30%–7.50% |
| Saving vs Domestic Market | ~70–137 bps |
Data as of June 8, 2026. SOFR source: FRED/NY Fed. Domestic rate: market participant interviews per ET.
NaBFID CEO Rajkiran Rai stated plainly that any rate below 7% is very good for borrowers like his institution. MUFG estimates the positive funding arbitrage at more than 1.25%.
The window has a shelf life, though. Bankers’ caution: if too many Indian companies rush overseas simultaneously, global lenders will start pricing in a supply premium, eroding the arbitrage over time.
The February 2026 ECB Overhaul: The Foundation Under This Story
The swap window did not arrive alone. RBI notified the Foreign Exchange Management (Borrowing and Lending) (First Amendment) Regulations, 2026, effective February 16, 2026, a significant shift toward a principle-based, market-aligned regulatory regime.
Key changes:
| Reform | Old Rule | New Rule (Feb 2026) |
|---|---|---|
| All-in cost ceiling | Benchmark + 500 bps cap | Removed — market-linked pricing |
| Automatic route ECB limit | $750 million | Higher of $1 billion or 300% of net worth Khaitan & Co |
| Eligible currencies | Freely convertible only | Any foreign currency or INR, A&O Shearman |
| Acquisition financing | Restricted | Permitted for strategic purposes by law |
| Eligible borrowers | Restricted list | Any Indian resident entity under Central/State Act |

The February reforms removed regulatory friction. The June swap window removed economic friction. Together, they have opened the ECB route wider than at any point in recent memory.
Which PSUs Are Poised to Move First
PSUs typically raise $10–12 billion annually through ECBs. Given the current window of opportunity and the cost advantage available, many are expected to front-load their borrowing plans as per Business Standard.
| PSU | Sector | Expected Move |
|---|---|---|
| Power Finance Corp (PFC) | Power sector lending | Likely front-loading |
| REC Ltd | Renewable / transmission | Likely front-loading |
| NaBFID | Infrastructure DFI | Confirmed post-guidelines |
| NTPC | Power generation capex | Probable |
| Indian Oil Corporation | Refinery / capex | Probable |
| Exim Bank | Trade finance | Likely |
PSU ECB issuances amounted to $4.9 billion in FY26, accounting for around 11% of total ECB issuances, with most carrying maturities of five to seven years, reports Business Standard.

Broader Impact: Rupee, Liquidity, and Bond Yields
SBI Research estimates total inflows from the RBI’s combined measures at $55–65 billion, which could strengthen the rupee to around 92 per dollar and push India’s balance of payments into a surplus of $5–10 billion in FY27, way above their previous estimate of a $65–70 billion deficit.
FCNR(B) deposits are estimated to bring in $40–45 billion, while the ECB/OFCB swap windows may garner another $15–20 billion.
The secondary domestic benefit: PSUs that would otherwise tap the domestic bond market borrow overseas instead, reducing onshore corporate bond supply and softening yields. That helps private corporates and NBFCs access cheaper rupee capital even without raising a single ECB themselves.
Sector read-through:
| Sector | Impact | Reason |
|---|---|---|
| PSU Infrastructure Lenders (PFC, REC, NaBFID) | Strongly Positive | Direct funding cost reduction |
| NBFCs | Positive | Reduced PSU bond supply eases onshore yields |
| Housing Finance Companies | Positive | Lower AAA/AA benchmark yields |
| Private Corporates (AA/AAA) | Positive | Less crowded domestic bond market |
| Rupee | Positive | Dollar inflows support currency |
| Banking System Liquidity | Positive | ECB proceeds park onshore |
Risks: What Could Unwind the Arbitrage
SOFR movement: The arbitrage is built on current SOFR at 3.63%. At SOFR above ~5%, the 7% viability threshold gets breached even with the RBI swap subsidy.
Demand bunching: If PSUs front-load three-to-five year ECBs before September 2026, repayment and refinancing pressures could also bunch later, which would matter if global rates rise, credit spreads widen, or the rupee weakens.
Spread compression: Barclays notes demand will still be constrained by the fact that global rates remain elevated, and lenders may reprice if Indian borrower supply spikes.
| Scenario | Est. All-in ECB Cost | Viable? |
|---|---|---|
| Current (SOFR ~3.63%) | ~6.1%–6.6% | ✅ Yes |
| SOFR rises to 5% | ~7.5%–8.0% | ❌ Borderline |
| Bank spread widens to 2% | ~7.1%–7.6% | ❌ Borderline |
| Combined adverse scenario | ~8.5%+ | ❌ No |

Bottom Line
The RBI’s 1.5% FX swap window is a rare, time-bound structural subsidy for PSU borrowers, arriving on top of the most significant ECB framework liberalisation in India’s history.
With SOFR verified at 3.63%, forex reserves confirmed at $682.3 billion, rupee depreciation at 4.9% in 2025 and 7.04% in the first five months of 2026, and the window closing September 30, 2026, the cost math is compelling today.
FIIs were already adding to PFC in Q4 FY26 before this announcement. Cheaper ECB liabilities ahead can only support that trend.
The NIM benefit will be gradual; lower funding costs could support NIMs over time, subject to asset repricing and overall funding mix, but it is directionally unambiguous for the country’s two largest power-sector lenders.
FAQs
What is the RBI FX swap facility for PSU ECBs?
It is a USD-INR swap window where a bank arranging a dollar loan for an eligible PSU sells those dollars to the RBI and buys them back at maturity at a fixed rate of 1.5% per annum compounded semi-annually. This subsidises hedging costs and brings all-in ECB costs to ~6.1%–6.6% for top-rated PSUs, below domestic bond rates of 7.30%–7.50%. The facility runs until September 30, 2026, as per RBI Circular dated June 8, 2026.
What $15 billion PSU ECB forecast is cited, and who made it?
Barclays estimates uptake of around $10–15 billion over the next few months. SBI Research’s Ecowrap report estimates the ECB/OFCB swap windows could bring in $15–20 billion in FY27. These are brokerage and research-house projections, not RBI targets.
How does the February 2026 ECB overhaul connect to the June swap window?
SBI Research describes the February and June 2026 measures as a coordinated attempt, the February measures being structural and market development-oriented, while the June measures aim to attract foreign currency inflows without raising domestic interest rates. The February reform removed the all-in cost ceiling and raised borrowing limits; the June swap window subsidises hedging costs. Together they form a complete package.
