RBI absorbs ₹2.9 lakh cr. to suck excess liquidity

1. At a Glance

• RBI conducted two Variable Rate Reverse Repo (VRRR) auctions on September 16, 2026, absorbing almost ₹2.9 lakh crore from the banking system [4].
• Part of RBI's ongoing liquidity management strategy amid a record system-wide surplus, driven largely by FCNR(B) deposit scheme inflows [5].
• Tests understanding of RBI's Liquidity Adjustment Facility (LAF) toolkit — a recurring UPSC Prelims/Mains theme in monetary policy and banking.
• Connects directly to broader Economy (GS-III) themes: money supply, interest rate transmission, and monetary policy operations.

2. Why in the News

• On September 16, 2026, RBI absorbed ₹2.9 lakh crore via two overnight VRRR auctions to mop up surplus liquidity from banks [4].
• First auction: target ₹2,50,025 crore; bids received ₹3,17,088 crore; RBI accepted ₹2.5 lakh crore at a cut-off/weighted average rate of 5.4% [4].
• Second auction: target ₹1 lakh crore; bids received only ₹40,302 crore (undersubscribed) [4].
• Banking system liquidity surplus was estimated at around ₹9.85 lakh crore as of September 15, 2026 [5].
• Earlier in the same month (around September 4), RBI had absorbed ₹6.02 lakh crore via VRRR auctions when surplus liquidity hit a record ₹10.32 lakh crore (as of Sept 3) [6].
• RBI also announced Open Market Operation (OMO) sales of government securities worth ₹1 lakh crore in three tranches (Sept 17, 21, 28) to durably absorb liquidity [5].

3. Background & Evolution

• Liquidity Adjustment Facility (LAF): RBI's core mechanism to manage short-term liquidity, comprising repo (injection) and reverse repo (absorption) operations.
• VRRR introduced as a tool to absorb surplus liquidity at market-discovered rates (rather than a fixed reverse repo rate), giving RBI flexibility to manage volatile liquidity conditions across tenures (overnight, 3-day, 7-day, 14-day, 28-day) [1].
• RBI has progressively shifted absorption from the fixed-rate overnight reverse repo window to VRRR auctions of varying maturities to better anchor short-term rates near the policy repo rate [1].
• Current liquidity glut (2026) traced to large capital inflows via the special FCNR(B) (Foreign Currency Non-Repatriable) deposit scheme, which pumped foreign currency-linked rupee liquidity into the banking system [5].
• Predecessor liquidity-absorption tools: fixed-rate reverse repo, Cash Reserve Ratio (CRR) hikes, Market Stabilisation Scheme (MSS), and OMO sales — all part of RBI's standard toolkit.

4. Core Static Facts

5. Multi-Dimensional Analysis

Economic

• Excess liquidity can suppress short-term money market rates below the repo rate, weakening monetary policy transmission; VRRR helps re-anchor rates to the policy stance.
• Large surplus can fuel excess credit growth/inflationary risk if unaddressed, especially post large forex inflows.

Administrative/Governance

• Reflects RBI's data-driven, flexible day-to-day liquidity management rather than relying solely on the CRR/policy rate.
• Under-subscription in the second auction (₹40,302 crore vs ₹1 lakh crore target) signals banks preferred to deploy funds elsewhere — indicates market-driven rate discovery under VRRR.

Geopolitical/External Sector linkage

• FCNR(B) scheme-driven liquidity surge shows how external capital flows (NRI deposits) directly affect domestic banking liquidity — a link between external sector management and monetary operations.

Scientific/Technological (Monetary Tools)

• Demonstrates layered use of instruments: VRRR (short-term, tactical) + OMO sales (durable, structural) — a textbook combination for calibrated liquidity absorption.

7. Prelims Hooks

• VRRR = Variable Rate Reverse Repo, a tool under RBI's Liquidity Adjustment Facility (LAF) [1].
• On September 16, 2026, RBI absorbed ₹2.9 lakh crore through two VRRR auctions [4].
• First VRRR auction cut-off rate on Sept 16, 2026 was 5.4%, same as weighted average rate [4].
• Second auction on Sept 16, 2026 was undersubscribed — bids of only ₹40,302 crore against a ₹1 lakh crore target [4].
• System liquidity surplus stood at ~₹9.85 lakh crore as of September 15, 2026 [5].
• Record surplus of ~₹10.32 lakh crore was recorded around September 3, 2026 [6].
• Surplus liquidity in 2026 driven mainly by inflows from the special FCNR(B) deposit scheme [5].
• RBI additionally announced OMO sales of ₹1 lakh crore in G-Secs across three tranches to durably absorb liquidity [5].
• VRRR differs from the fixed-rate reverse repo: rate is market-determined via auction, not fixed by RBI [1].
• RBI has been shifting liquidity absorption from the fixed-rate overnight window to VRRR auctions of varying maturities (3-day, 7-day, 14-day, 28-day) [1].
• FCNR(B) = Foreign Currency Non-Repatriable (Bank) deposits — a NRI deposit scheme whose inflows affect domestic liquidity [5].
• LAF (Liquidity Adjustment Facility) is RBI's primary short-term liquidity management framework, comprising repo and reverse repo operations.

8. Why Banks Refused Half the Money RBI Asked For

• Money put in a VRRR is locked. Money in the SDF is not.
• In a VRRR auction the bank hands cash to RBI for a fixed period — overnight, 7 days, 30 days. It cannot take the cash back early.
• The Standing Deposit Facility (SDF) is the other window where banks park spare cash with RBI. There is no auction and no lock-in — the bank can pull the money out the next morning. The SDF rate was 5% in mid-2025 [10].

• So a bank compares two things: a slightly higher auction rate, or the freedom to walk away. When it expects to need cash soon, it picks freedom.

• That is exactly what happened in September 2026.

• On 16 September the second auction got bids of only ₹40,302 crore against a ₹1 lakh crore target [4].
• Nine days earlier, a 30-day VRRR auction of ₹7 lakh crore drew bids of just ₹2.59 lakh crore [8].

• The reason was not a shortage of cash. Banks were holding money back for GST and advance tax payments, when companies pull large sums out of their bank accounts to pay the government [8].

• Read the pattern, not the one auction. The longer the tenor RBI offers, the weaker the response. Overnight auctions fill; 30-day auctions do not [4] [8]. RBI can set the target, but it cannot force the money in — the bank decides.

9. Absorbing Is Not Removing — Why the Surplus Keeps Coming Back

• An overnight VRRR returns the money the next day.
• RBI takes the cash in the evening and gives it back, with interest, the next morning. Then it must run the auction again.

• So the same rupee can be "absorbed" many times in one month. The daily absorption figure is not the amount of extra cash removed from the system.

• The numbers show this clearly.

• Around 4 September 2026 RBI absorbed ₹6.02 lakh crore [6].
• Yet on 15 September the surplus was still about ₹9.85 lakh crore [5].

• Nothing was destroyed. The tide was only held back for a day at a time.

• This is why RBI moved to OMO sales. An Open Market Operation (OMO) sale means RBI sells government bonds to banks. The banks pay cash and keep the bonds. That cash does not come back the next morning — it is gone from the system. RBI announced ₹1 lakh crore of such sales in three tranches [5].

• The exam point: VRRR manages the flow of cash day to day. OMO sale cuts the stock of cash permanently. A big VRRR number is a sign the problem is still there, not a sign it is solved.

10. The 2025 Rulebook Change That Shapes These Auctions

• RBI rewrote its own liquidity handbook on 30 September 2025, after an internal working group set up in August 2025 studied the question [9].
• What stayed the same — the target rate.
• The WACR (weighted average call rate) is the average interest rate at which banks lend to each other overnight.
• RBI kept WACR as its operating target — the one number it tries to keep close to the repo rate [9].

• Some market analysts had argued for switching to TREPS, a different overnight rate where lending is backed by collateral [9]. RBI did not switch.

• What changed — the main tool got shorter.

• The old framework used the 14-day VRR/VRRR as the main operation. The 2025 framework replaced it with mainly 7-day operations, plus other tenors from overnight to 14 days as needed [9].

• RBI also promised at least one day's advance notice of the tenor, amount and timing of each operation, so banks can plan their cash [9].

• Why this matters for the September 2026 story. Shorter tenors and advance notice were meant to make banks more willing to bid. The undersubscribed auctions show that when banks fear a tax outflow, even a friendlier rulebook does not bring the money in [4] [8].

11. The Case for Leaving the Surplus Alone — and RBI's Answer

• The opposing argument, stated at its strongest.
• Extra cash in banks pushes down lending rates. After a rate-cut cycle, that is what RBI wants — cheaper loans for firms and households.
• The money arrived from abroad through the FCNR(B) deposit scheme [5]. Draining it looks like RBI undoing its own success in pulling in foreign money.

• Every rupee absorbed is a rupee the bank did not lend. Running ₹2.9 lakh crore of auctions in a single day [4] is a lot of effort to fight a condition that helps borrowers.

• What is right about that argument. RBI's own later review found the WACR was better aligned with the repo rate once liquidity conditions improved [11]. So the surplus was not a permanent disaster, and constant heavy-handed absorption was not the only path.

• RBI's answer, and why it holds.
• When cash is this heavy, the call rate does not just fall below the repo rate — it can fall below the SDF rate, which is meant to be the floor of the corridor [10].
• If the floor breaks, the repo rate stops being the price that guides the market. The MPC could announce any rate and the money market would ignore it.
• So the absorption is not aimed at credit growth. It is aimed at keeping the policy rate meaningful. That is the honest defence — and it concedes the cost: some lending is squeezed to protect the signal.

12. Anchors for Answers

• Data: Banking system liquidity surplus of about ₹9.85 lakh crore on 15 September 2026, against a record ₹10.32 lakh crore on 3 September 2026 [5] [6]
• Data: 30-day VRRR auction of ₹7 lakh crore drew bids of only ₹2.59 lakh crore in September 2026 — proof that absorption depends on bank willingness, not RBI's target [8]
• Report/Committee: RBI Internal Working Group on the Liquidity Management Framework — set up August 2025; revised framework announced 30 September 2025, retaining WACR as operating target and replacing the 14-day VRR/VRRR with mainly 7-day operations [9]
• Law/Case: Reserve Bank of India Act, 1934 — Section 17 gives RBI the power to conduct repo and reverse repo operations in government securities
• Scheme: Special FCNR(B) deposit scheme — the NRI deposit inflow that created the 2026 surplus, linking external sector policy to domestic liquidity [5]
• Scheme: Standing Deposit Facility (SDF), rate 5% in mid-2025 — the no-collateral, no-lock-in parking window that competes with VRRR for bank money [10]

15. Common Errors / Trap Areas

• Confusing VRRR (liquidity absorption tool, RBI borrows from banks) with VRR/Variable Rate Repo (liquidity injection tool, RBI lends to banks).
• Assuming a fixed reverse repo rate applies — VRRR rate is auction/market-determined, can exceed or differ from the fixed reverse repo rate.
• Mixing up the cut-off rate with the policy repo rate — they are related but not identical, especially when liquidity is in surplus.
• Attributing the 2026 liquidity surplus solely to demonetisation-era or COVID-era liquidity infusions instead of the current cause — the FCNR(B) deposit scheme inflows.
• Treating VRRR and OMO as interchangeable — VRRR is short-term/tactical, OMO sale is a durable/structural liquidity absorption tool.
