The RBI has turned to a major open-market bond sale after a massive foreign-currency inflow left India’s banking system awash with rupees. The move could pull short-term rates back toward the policy corridor, but it also raises a fresh risk for government bond yields and borrowing costs.
The Reserve Bank of India has escalated its battle against excess liquidity, announcing a ₹1 lakh crore open-market sale of government securities over the next fortnight.
The RBI will sell ₹50,000 crore on September 17, followed by ₹25,000 crore each on September 21 and September 28, taking the total operation to ₹1 lakh crore, or roughly $10.47 billion. The first tranche will comprise government securities maturing between fiscal 2029 and fiscal 2032.
The decision came hours after RBI Governor Sanjay Malhotra said the central bank had several tools available to absorb excess liquidity, including open-market operations and foreign-exchange swaps, and that “nothing is off the table.”
The timing is important.
India’s banking system has been left with an unusually large rupee surplus after banks mobilised a much bigger-than-expected amount of foreign currency through the RBI’s special forex mobilisation programme.
That has created an unusual policy problem: a programme that strengthened India’s foreign-exchange buffers has simultaneously created a domestic liquidity glut that the RBI now needs to sterilise.
Key Takeaways
- ₹1 lakh crore: RBI’s planned government bond sales over three tranches.
- $127.23 billion: FCNR(B) deposits mobilised under the special forex scheme by August 31.
- ₹10 lakh crore+: System liquidity has recently remained at exceptionally high levels.
- 7%+: India’s benchmark 10-year government bond yield crossed 7% on September 11.
- Next trigger: The September 17 bond sale will provide an early test of market demand and yield pressure.
RBIS LIQUIDITY DRAIN
Why the RBI is draining liquidity now
The root of the problem lies in the scale of foreign-currency mobilisation.
RBI data showed that its special forex measures had attracted $136.38 billion by August 31. Of that, $127.23 billion came through FCNR(B) deposits, while overseas foreign-currency borrowings contributed $5.26 billion and external commercial borrowings another $3.89 billion.
The response was far stronger than the market initially expected.
Earlier projections for the FCNR(B) component had been around $40–50 billion, but the final mobilisation was more than twice the upper end of that range.
The foreign currency itself is not the problem.
The subsequent conversion and RBI operations injected rupee liquidity into the banking system. At one point, system liquidity had risen to around ₹10.32 lakh crore, while later readings showed the surplus moving above ₹11 lakh crore.
That much excess cash can pull overnight market rates below the RBI’s desired operating zone.
And that is exactly the situation the central bank now wants to correct.

The RBI has already tried shorter-term tools
The OMO announcement did not come out of nowhere.
The RBI had been using variable-rate reverse repo (VRRR) operations and foreign-exchange swaps to absorb excess funds.
But the response from banks to some longer-duration operations was weaker than the RBI would have preferred. A September 7 VRRR operation, for example, received only about ₹2.59 lakh crore of bids against ₹7 lakh crore notified, highlighting the difficulty of absorbing the entire surplus through that route.
That distinction matters.
Rather than relying entirely on repeated short-term operations, the RBI has now moved toward a more durable liquidity-absorption mechanism.
RBI’s latest liquidity operation
| Operation | Amount | Date |
|---|---|---|
| First OMO bond sale | ₹50,000 crore | September 17 |
| Second OMO bond sale | ₹25,000 crore | September 21 |
| Third OMO bond sale | ₹25,000 crore | September 28 |
| Total | ₹1 lakh crore | Next fortnight |
The first sale is therefore the key immediate market test.

The bond-market problem is getting bigger
The RBI’s move solves one problem but potentially creates another.
When the central bank sells government securities, the market has to absorb additional bond supply.
If demand is strong, the impact on yields may remain manageable. If investors demand higher returns to absorb the supply, bond prices can fall and yields can rise.
That risk is arriving at an uncomfortable time.
India’s benchmark 10-year government bond yield crossed 7% on September 11, reaching about 7.0211%, its highest level in more than three months, after closing at 6.9762% the previous day.
The rise has come as oil prices and US Treasury yields have pressured Indian bonds.
This makes the September 17 auction particularly important.
The RBI wants to remove excess liquidity without allowing the bond market to become the next source of financial tightening.
That is the central market tension.
Oil adds another layer of risk
The liquidity operation is also taking place against a sharply different commodity backdrop.
Brent crude was around $104.35 a barrel in Friday trading after briefly moving higher earlier in the session. Reuters reported that Brent remained on course for a weekly gain of more than 8% amid concerns over supply disruptions linked to geopolitical tensions.
For India, sustained oil strength can complicate both inflation and the rupee.
Indian equities also ended the week under pressure. The Nifty 50 fell 0.34% to 23,398.1, while the Sensex declined 0.16% to 74,781.76 on Friday. Both benchmarks lost more than 2% during the week.
The rupee also recorded its sharpest weekly decline since mid-May, according to Reuters.
This leaves the RBI managing several variables simultaneously:
| Market pressure | Why it matters |
|---|---|
| Excess banking liquidity | Can push overnight rates below the desired corridor |
| Higher crude oil | Adds inflation and current-account pressure |
| Rising bond yields | Raises government borrowing-cost concerns |
| Weaker rupee | Can amplify imported inflation |
| Global Treasury yields | Can reduce demand for Indian bonds |
Inflation is the next major test
The liquidity decision also comes ahead of India’s August CPI release due on September 14.
A Reuters poll of 44 economists had forecast consumer inflation at 4.80% in August, up from 4.45% in July and potentially a 20-month high. That would mark a third consecutive month above the RBI’s 4% medium-term target, although still within the central bank’s 2%-6% tolerance band.
The inflation number matters because the RBI’s liquidity operations are taking place while oil prices are rising sharply.
If inflation remains contained, the central bank has greater flexibility to treat the current operation primarily as a liquidity-management exercise.
If inflation accelerates more than expected, however, the market could begin to price a more persistent tightening bias.
That is where the expectation gap becomes important.
The RBI has not announced a repo-rate hike. But investors are watching whether liquidity management, inflation and oil eventually force a broader shift in the interest-rate outlook.
What traders should watch next
1. September 17 OMO auction
The first ₹50,000 crore sale will show how comfortably the bond market can absorb the additional supply.
2. 10-year G-Sec yield
A sustained move above 7% would indicate that liquidity absorption is occurring alongside meaningful bond-market pressure.
3. Overnight money-market rates
The RBI’s objective is not simply to remove cash but to bring money-market conditions back toward its intended operating framework.
4. USD/INR
The rupee remains vulnerable to the combined impact of crude prices, global yields, and foreign flows.
5. Brent crude
A prolonged move above $100 would make the inflation challenge more complicated for India.
6. Further RBI operations
If excess liquidity remains elevated, the ₹1 lakh crore operation may not be the final step. Governor Malhotra’s comments indicate that the central bank retains multiple tools, including OMOs and FX swaps.
The bigger picture
The RBI’s latest decision is more significant than a routine government-bond transaction.
The central bank is effectively moving from short-term liquidity absorption toward a more durable drain after the banking system accumulated an unusually large cash surplus.
The irony is that the surplus was partly created by the success of the RBI’s own foreign-currency mobilisation programme.
The FCNR(B) window ultimately attracted $127.23 billion, while total mobilisation across the covered routes reached $136.38 billion.
Now the RBI has to manage the rupees generated by that success.
The immediate question for markets is therefore not simply whether the central bank can absorb ₹1 lakh crore.
It is whether it can do so without pushing government bond yields materially higher at a time when crude oil is already above $100 and global yields are elevated.
The September 17 auction should provide the first major signal.
If demand is strong, the RBI could achieve a cleaner liquidity reset. If bond investors demand significantly higher yields, the operation could expose a new fault line between liquidity control and borrowing costs.
For traders, that makes the RBI’s next bond auction one of the most important market events to watch in the coming week.
