RBI Rejects All Bids for Rs 23000 Crore Treasury Bill Auction as Short-Term Yields Surge

The Reserve Bank of India (RBI) took an aggressive stance against rising borrowing costs on Wednesday by rejecting all bids received in its scheduled weekly Treasury bill (T-bill) auction. The federal government had sought to borrow Rs 23,000 crore ($2.43 billion) across three tenors: Rs 8,000 crore each in 91-day and 182-day papers, and Rs 7,000 crore in 364-day papers.

Despite receiving bids that substantially exceeded the notified issuance amount across all three maturities—including 67 competitive bids worth Rs 15,366.60 crore for the 91-day tenor alone—the central bank accepted none, exercising its discretion to prevent cut-off yields from establishing elevated benchmarks for short-term sovereign paper.

Factors Behind the Standoff

Money market participants attributed the standoff between bidders and the debt manager to an abrupt tightening in system liquidity, driven by several compounding domestic factors:

• Liquidity Drain: Outflows related to Goods and Services Tax (GST) collections and high government cash balances significantly curtailed surplus cash in the banking system.
• Capital Lock-ups: Substantial market funds remained blocked in mega primary market issues, including the Jio Platforms IPO subscription, temporarily restricting institutional liquidity.
• Aggressive Rate Expectations: Bond desks factored in at least another 75 basis points of potential rate hikes, causing investors to demand steeper yields before committing balance sheet space to short-term paper.

Over the five weeks preceding the auction, cut-off yields on 91-day, 182-day, and 364-day T-bills had jumped by 64 basis points, 83 basis points, and 69 basis points, respectively. By the previous week, the yield on 364-day paper sat 99 basis points above the RBI policy repo rate—its widest spread in four years.

Cut-Off Yield Expectations vs Reality

In the preceding auction, the RBI had set cut-offs at 5.73% for 91-day notes, 6.29% for 182-day notes, and 6.49% for 364-day paper. Heading into Wednesday's sale, a Reuters poll projected cutoff yields rising further to 5.85%, 6.42%, and 6.60% across the three maturities.

With the benchmark 10-year government bond yield hovering near 7.44%, dealers demanded yields well above previous levels. Given that the central government is currently running comfortable cash reserves and is not facing urgent cash pressures, the RBI opted for a full auction cancellation rather than endorsing runaway borrowing costs.

Implications for Indian Markets and Investors

The auction rejection serves as an explicit signal to money markets that the central bank will not validate aggressive yield spikes that could disrupt short-term lending rates and corporate debt pricing.

For retail and institutional investors, the decision carries direct implications across domestic asset classes:

• Debt Mutual Funds: Liquid, ultra-short duration, and money market mutual funds face yield volatility as fund managers navigate the policy signaling and potential portfolio revaluations.
• Corporate Borrowing Rates: Commercial paper (CP) and Certificate of Deposit (CD) rates, which use T-bill yields as a core pricing benchmark, are likely to see pricing resistance rather than an unchecked climb.
• Banking Sector: The signal implies the RBI intends to keep money market rates anchored, curbing sudden spikes in short-term marginal cost of funds-based lending rates (MCLR).

Market desks expect liquidity conditions to normalize as GST-related government spending flows back into the banking system, which should narrow the divergence between bidder demands and the central bank's target yields in subsequent auctions.
