RBI Cancels T-Bill Auction to Manage Yields and Boost Liquidity

Introduction

The Reserve Bank of India (RBI) took the rare step of rejecting all bids at its weekly Treasury bill auction on Wednesday, March 25, 2026. The central bank's decision to cancel the planned ₹35,000 crore issuance was driven by elevated yield expectations from market participants. This move is widely seen as a strategic intervention to support banking system liquidity and prevent a signal of higher interest rates ahead of the financial year-end.

An Unusual Intervention

Market dealers noted that the complete cancellation of a weekly T-bill auction is a highly unusual event, possibly the first in a decade. The government had intended to raise funds through the sale of 91-day, 182-day, and 364-day Treasury bills. However, the bids submitted by banks and primary dealerships were reportedly at levels the RBI deemed too high. By rejecting these bids, the central bank avoided locking the government into higher borrowing costs and sending a hawkish signal to the broader market. A dealer at a primary dealership explained that with the government's cash position being comfortable, the RBI was not under pressure to accept unfavorable terms.

The Liquidity Context

The RBI's action comes at a time of fluctuating liquidity conditions. In the preceding days, the banking system had experienced some tightness due to outflows for advance tax payments and the RBI's interventions in the foreign exchange market. However, the latest data from the central bank showed that net liquidity had returned to a surplus of ₹61,628 crore on Tuesday. The cancellation of the auction is expected to further ease conditions. Inflows from maturing Treasury bills are due on Friday, and with no corresponding outflow from a new auction, the system will receive a net liquidity injection, which is crucial for smooth operations at the close of the financial year.

Government's Strong Fiscal Position

A key factor enabling the RBI's decision was the government's robust fiscal health. With an estimated cash balance of ₹4.5 trillion, the government is not immediately dependent on market borrowings. This comfortable buffer provided the central bank with the flexibility to prioritize market stability over raising funds. The move underscores the RBI's focus on managing yield expectations and ensuring that borrowing costs remain anchored, especially when underlying economic conditions do not warrant a spike.

Auction Details at a Glance

To provide a clear summary of the event, the key details of the cancelled auction are outlined below.

Impact on the Bond Market

The bond market has been under pressure recently from both domestic and global factors. The yield on the benchmark 10-year government bond settled at 6.88% on Wednesday, a marginal increase from its previous close of 6.87%. Notably, the yield has hardened by 22 basis points during March, reflecting market concerns over inflation and future rate movements. The RBI's intervention is a clear signal of its intent to counter this upward pressure on yields and maintain orderly market conditions. This action helps alleviate some of the pressure caused by foreign capital outflows and the persistent gap between credit and deposit growth.

Historical Precedent

While a complete rejection of all bids is rare, the RBI has used auction cancellations as a policy tool in the past. In February 2025, the central bank cancelled auctions for 91-day and 182-day T-bills but proceeded with the 364-day auction. According to RBI data, the last time it rejected bids for 91-day T-bills was on March 29, 2023, and for 182-day T-bills was on February 24, 2016. The decision to cancel all three tenors simultaneously highlights the central bank's strong conviction in its current stance.

Looking Ahead

With the final auction of the financial year cancelled, market attention is now firmly on the upcoming borrowing calendar for the April-June quarter of the new fiscal year. Traders anticipate that the government may front-load its financing needs, potentially leading to a sharp increase in short-term borrowing in the first quarter. The release of this calendar, expected by the end of March, will provide crucial guidance on the government's borrowing trajectory and its potential impact on market liquidity and yields in the coming months.

Conclusion

The RBI's decision to cancel the T-bill auction was a proactive and strategic measure to maintain stability in the financial markets. By leveraging the government's strong cash position, the central bank successfully avoided signalling higher interest rates and provided essential liquidity support ahead of the fiscal year-end. This move reinforces the RBI's commitment to managing market expectations and ensuring a smooth transmission of its monetary policy.
