The Reserve Bank of India (RBI) has recently unveiled a comprehensive set of directives aimed at formalizing acquisition financing and bolstering the resilience of the capital markets, marking a pivotal moment for India’s financial sector. These parallel regulatory adjustments, while intended to bring greater clarity and stability, have elicited a nuanced response from financial institutions and market participants, underscoring the complexities of balancing economic dynamism with prudential oversight. The central bank’s move to delineate explicit parameters for bank funding of mergers and acquisitions (M&A), alongside tightening collateral requirements for broker lending, signals a strategic pivot towards a more structured and risk-mitigated financial ecosystem as India’s economy continues its robust expansion.
The most significant development in corporate finance is the RBI’s formal allowance for banks to fund acquisition deals, particularly where an existing acquirer seeks to increase its stake in a target company from 26% up to 90%. This move addresses a long-standing "grey area" in Indian banking, where such financing largely operated under broad prudential capital market exposure limits rather than specific guidelines. Historically, acquisition financing in India has often relied on a mix of internal accruals, equity infusions, and non-bank funding sources, including private equity and foreign debt, due to the absence of clear banking regulations. The new framework, effective from April, seeks to integrate domestic banks more directly into the nation’s burgeoning M&A landscape, potentially unlocking a new avenue for corporate growth and consolidation in sectors ranging from manufacturing to technology and infrastructure.
However, this newfound flexibility comes tethered with stringent conditions designed to safeguard the banking system from undue risk. For listed companies, borrowers must demonstrate a minimum net worth of ₹500 crore (approximately $60 million USD) and a track record of net profits for three consecutive years. Unlisted entities, conversely, are required to secure an investment-grade credit rating from a recognized agency prior to loan disbursement. These criteria aim to channel bank funding towards financially sound and established entities, thereby mitigating risks associated with highly speculative or undercapitalized transactions. Furthermore, the RBI has increased the permissible exposure limit for acquisition financing to 20% of a bank’s eligible capital base, a significant upward revision from the 10% initially proposed in its October draft guidelines, reflecting an acknowledgement of industry feedback and a desire to provide greater operational leeway. Banks are now permitted to fund up to 75% of the acquisition cost, with the remaining 25% mandated as equity contribution from the acquirer, establishing a clear risk-sharing mechanism.
Despite the increased exposure cap and formalized framework, the banking sector’s enthusiasm appears tempered by the prescriptive nature of the new guidelines. While some experts, like Sanjay Agarwal, Senior Director at Care Ratings, initially viewed the increased leeway of 20% and the 75-25 funding split as a ‘soft approach’ providing banks with more accommodation while containing risks, other bankers express significant reservations. A prevailing sentiment suggests that the detailed eligibility filters and exposure caps might inadvertently constrain the market. A senior private sector banker, speaking anonymously, voiced concerns that "every transaction is unique," arguing that a more principles-based approach with board-approved policies and broad capital market limits would offer greater flexibility than highly prescriptive mandates. This perspective highlights a fundamental tension between regulatory specificity and the dynamic, often bespoke, nature of M&A deals.
The concerns extend to competitive disadvantages. Indian banks operating under these strictures will find themselves competing with foreign banks and the rapidly expanding private credit market, both of which often have greater freedom in structuring complex acquisition finance deals. Globally, leveraged buyouts (LBOs) are a cornerstone of M&A activity in mature markets like the United States and Europe, where a robust ecosystem of investment banks, private equity firms, and diverse debt providers facilitates multi-billion-dollar transactions. The Indian regulations, while prudent, may limit the universe of transactions that domestic banks can participate in, potentially funneling larger or more intricate deals towards alternative financing channels. This could, in turn, curb the ambition of Indian corporates seeking to undertake large-scale consolidation or strategic acquisitions vital for national economic growth and global competitiveness.
Recognizing the intricacies involved, the RBI’s objective appears to be two-fold: to encourage greater involvement of Indian banks with their clients in the M&A space, while simultaneously tightening guardrails around financial risk. This necessitates a significant uplift in capabilities within domestic banks. Indeed, the guidelines are prompting lenders to invest in specialized M&A teams with expertise in deal structuring, due diligence, and comprehensive risk evaluation. State Bank of India (SBI), the nation’s largest lender, has already begun this process, establishing a dedicated team in coordination with its investment banking arm, SBI Capital Markets, to build institutional capability. Other public sector banks are also planning to either re-skill existing staff or recruit laterally to meet these specialized requirements, underscoring the operational transformation required to navigate the new regulatory landscape effectively. The transition period leading up to the April implementation will be critical for banks to refine their internal policies and build the necessary infrastructure.
In parallel to the M&A directives, the RBI has also significantly tightened collateral requirements for bank funding extended to brokers, a move designed to enhance systemic stability within India’s dynamic capital markets. This revision comes at a time when India has witnessed an unprecedented surge in retail participation and a burgeoning derivatives market, making the financial system more susceptible to volatility and potential contagion. Previously, broker funding structures often relied on a mix of bank guarantees, personal guarantees, or corporate guarantees, sometimes without explicit, standardized norms for collateral composition. This created a potential vulnerability, as the underlying assets backing these guarantees might not have been sufficiently liquid or transparent in times of market stress.
Under the revised regulations, bank guarantees issued on behalf of brokers must now be supported by at least 50% tangible collateral. This tangible collateral must further be segmented, with half (25% of the total guarantee value) in cash and the remaining half in high-quality liquid assets. The RBI has specifically defined eligible high-quality liquid assets to include government securities, sovereign gold bonds, listed equities, and mutual fund units. For proprietary trading exposure – where brokers use their own capital for market activities – bank finance must now be fully secured with clearly specified, high-quality collateral. This fundamental shift from an "identity-based" collateral approach, which accepted guarantees based on the financial standing of individuals or entities, to a more "system-based" approach, focused on the intrinsic quality and liquidity of the underlying assets, fundamentally alters the risk profile for banks and bolsters financial stability.
The rationale behind these stringent collateral norms is to materially enhance the banking system’s resilience and reduce the likelihood of stress transmission during episodes of heightened market volatility. The RBI aims to prevent a situation where a significant market downturn could lead to widespread defaults among brokers, subsequently impacting the banks that have extended credit. By ensuring that a substantial portion of the funding is backed by highly liquid and tangible assets, the central bank is building a stronger buffer against potential shocks, aligning India’s financial market infrastructure with global best practices observed in developed economies. This proactive step is crucial for maintaining investor confidence and ensuring the orderly functioning of India’s rapidly expanding financial markets.
The tightened broker funding rules have elicited a mixed, albeit largely optimistic, response from market participants. For large, well-capitalized brokerage firms that already maintain prudent daily mark-to-market risk controls and robust liquidity buffers, the immediate impact on trading volumes is generally expected to be minimal. Industry experts like Dhiraj Sachdev, Chief Investment Officer at Roha Venture, suggest that such firms are well-positioned to adapt to the new standards, particularly with a sufficient transition period provided. Kruti Shah, Quant Analyst at Equirus, echoed this sentiment, stating that most proprietary trading firms possess "sufficient wherewithal" to operate without heavily relying on external bank funds, often being backed by family-run brokerages with strong capital bases and diversified revenue streams.
However, not all market observers share this sanguine outlook. K. Suresh, President of the Association of National Exchanges Members of India (AnMI), a prominent broker forum, expressed concerns that market volumes could indeed suffer. His apprehension stems from the fundamental shift in collateral requirements, moving away from personal and corporate guarantees towards strictly tangible, system-based assets. This could particularly affect smaller and mid-sized brokerages whose access to liquid collateral might be more constrained, potentially leading to a reduction in their proprietary trading activities or forcing them into consolidation.
Proprietary trading plays a crucial role in the liquidity and price discovery mechanisms of Indian capital markets. In 2025, proprietary traders accounted for a significant 29.7% share of the gross turnover on the National Stock Exchange’s cash segment, making them the second-largest participant group after retail investors (33.6%). Their dominance is even more pronounced in the highly liquid equity options segment, where prop traders contributed a staggering 50.8% of premium turnover, surpassing retail traders who held a 37.1% share. Any substantial curtailment of proprietary trading activity, therefore, has the potential to impact overall market liquidity, bid-ask spreads, and the efficiency of price discovery, particularly in the derivatives market. While the long-term benefit of enhanced stability is clear, the short-to-medium term could see some adjustments in market dynamics and possibly a period of consolidation among brokerage firms. The new rules might also compel brokers to optimize their capital allocation strategies, potentially leading to a more efficient deployment of resources but also higher operational costs.
The RBI’s twin regulatory initiatives represent a sophisticated attempt to mature India’s financial architecture, steering it towards greater transparency, accountability, and resilience. By formalizing acquisition finance, the central bank aims to unleash domestic capital for corporate restructuring and growth, albeit within a carefully constructed framework that prioritizes financial prudence. Simultaneously, the tighter collateral requirements for brokerage funding underscore a proactive stance against systemic risks, particularly given the rapid expansion and increasing complexity of India’s capital markets. While these directives are likely to reshape operational strategies for banks and brokers, and potentially influence market dynamics, their overarching intent is to foster a robust, stable, and globally competitive financial ecosystem capable of supporting India’s ambitious economic trajectory. The coming months will reveal how effectively the industry adapts to these new guardrails, balancing the imperative for growth with the critical need for financial stability.
