Bank Nifty Falls Nearly 200 Points as RBI Liquidity Steps and Spiking Bond Yields Hit Bank Stocks

The Nifty Bank index dropped nearly 200 points on Monday as banking heavyweights came under sustained selling pressure. A combination of liquidity-absorbing measures announced by the Reserve Bank of India (RBI) and a sharp surge in domestic sovereign bond yields triggered a broad sell-off across prominent lenders, including State Bank of India (SBI), ICICI Bank, and Axis Bank.

The banking gauge slipped 197 points, or 0.36 percent, to trade at 55,059.50 in morning trade, reversing its early advances after opening at 55,350.15 and reaching an intraday high of 55,416.45. The downturn materialized despite a firming domestic currency, which gained nearly 1 percent against the US dollar following the central bank's weekend policy steps.

RBI Tightens Systemic Liquidity

The retreat in bank counters was primarily driven by central bank actions designed to rein in surplus liquidity:

• Government Bond Sales: The RBI announced plans to auction Rs 25,000 crore worth of government securities, a transaction structured to directly mop up excess cash from the banking system.
• Stricter CRR Maintenance Rules: The regulator raised the minimum daily Cash Reserve Ratio (CRR) maintenance threshold for lenders from 90 percent to 99 percent, taking effect October 16. This mandate curbs treasury managers' flexibility in managing required reserve balances on a day-to-day basis.
• Foreign Exchange Interventions: The central bank introduced a special US dollar window designated for three state-run oil marketing companies to support the Indian rupee. While stabilizing the currency, foreign exchange operations of this nature tend to drain rupee liquidity, compounding tightness in the system.

Surging Yields Spark Mark-to-Market Concerns

Adding to the sector's woes, Indian government debt prices declined sharply, sending benchmark borrowing costs higher. The 10-year benchmark government bond yield spiked to 7.3707 percent—its highest level in three years—up from 7.2994 percent at the previous close. The 10-year yield has now climbed for eight consecutive weeks, rising 54 basis points over that period.

Because rising bond yields depress underlying bond prices, banking institutions face elevated mark-to-market (MTM) losses on their available-for-sale government securities portfolios. Furthermore, tighter liquidity conditions threaten to push up short-term borrowing and deposit costs, dampening treasury income and compressing net interest margins for commercial lenders.
