SBI to issue first rupee-denominated perpetual debt of 2026: Report

State Bank of India's decision to issue its first rupee-denominated perpetual debt of 2026 marks a significant development in India's banking capital management strategy. The bank aims to raise ₹5,000 crore through Basel III-compliant Additional Tier-1 (AT1) bonds with a five-year call option, expected to be completed by early August 2026. This move comes after Canara Bank's similar issuance in November 2025, indicating a broader trend among public sector banks to strengthen their capital buffers under the Basel III framework. To understand the significance, we must first grasp the Basel III norms. Introduced by the Basel Committee on Banking Supervision (BCBS) after the 2008 global financial crisis, these norms mandate higher quality capital, better risk coverage, and leverage ratios. India adopted Basel III guidelines in 2013 under the Reserve Bank of India's (RBI) phased implementation plan, with full compliance required by March 2020. Under these norms, banks must maintain a minimum Common Equity Tier-1 (CET1) ratio of 5.5%, a Tier-1 capital ratio of 7%, and a total capital ratio of 9%, plus a Capital Conservation Buffer (CCB) of 2.5%. Perpetual bonds, classified as AT1 capital, are crucial instruments for meeting Tier-1 requirements. They have no maturity date but typically carry a call option — here, five years — allowing the issuer to redeem them after that period. Importantly, AT1 bonds are loss-absorbing: they can be written down or converted into equity if the bank's CET1 ratio falls below a specified threshold (5.5% for Indian banks). This feature was dramatically tested in 2020 when Yes Bank's AT1 bonds were fully written down to zero during its reconstruction, a landmark event that reshaped investor perception of these instruments. SBI, as India's largest public sector bank with a balance sheet size exceeding ₹60 lakh crore, plays a systemic role. Its capital adequacy directly impacts financial stability. As of March 2025, SBI's capital adequacy ratio stood at around 14.5%, well above regulatory minimums. However, with credit growth projected at 13-14% for FY26 and the government's push for infrastructure lending, proactive capital raising is prudent. The ₹5,000 crore issuance will bolster SBI's Tier-1 capital, providing headroom for lending to priority sectors like MSMEs, agriculture, and green energy — aligning with national priorities such as the PM Gati Shakti National Master Plan and the Net Zero by 2070 commitment. The timing is also notable. With the RBI maintaining the repo rate at 6.5% since February 2023 and inflation trending toward the 4% target, bond yields have stabilized, creating a favorable window for issuance. The 10-year G-sec yield hovered around 6.95-7.05% in July 2026, allowing SBI to price its perpetual bonds competitively, likely with a spread of 150-200 basis points over the sovereign curve. Constitutionally, banking falls under the Union List (Entry 45, Seventh Schedule), giving Parliament exclusive legislative power. The Banking Regulation Act, 1949, and the RBI Act, 1934, form the statutory backbone. The RBI's Master Direction on Basel III Capital Regulations (2015, updated periodically) operationalizes these norms. Additionally, the Insolvency and Bankruptcy Code, 2016, provides the resolution framework that underpins the credibility of loss-absorbing instruments like AT1 bonds. Looking ahead, this issuance may trigger a wave of AT1 bond offerings from other PSBs like Punjab National Bank, Bank of Baroda, and Union Bank of India, which also need to replenish capital buffers. The success of SBI's issue will be a barometer for investor appetite, especially after the Yes Bank episode. For aspirants, this episode encapsulates the interplay of monetary policy, financial regulation, public sector governance, and capital markets — a quintessential topic for UPSC, RBI Grade B, and banking exams.
