RBI's 2026 framework for bank-led acquisition finance: Key changes

The Reserve Bank of India (RBI) has unveiled a revised regulatory framework for bank-led acquisition finance, set to take effect in 2026. The new rules mark a significant shift in how lenders fund corporate takeovers and mergers.

Banks have traditionally used acquisition finance to back buyouts, often structuring large loans against the target company's assets. The RBI's latest circular tightens these norms, aiming to prevent excessive leverage and systemic risk.

Stricter exposure limits and risk weights

Under the 2026 framework, banks face a cap on single-borrower exposure for acquisition finance. The RBI has set this at 20% of a bank's tier-1 capital, down from the earlier informal ceiling of 25%.

Risk weights on acquisition loans have also been revised upward. Loans backed by shares or intangible assets now attract a higher capital charge, forcing banks to set aside more funds. This directly impacts return on equity for lenders.

The central bank has clarified that acquisition finance must be treated as a distinct asset class, separate from working capital or term loans. This means banks cannot bundle these loans with other exposures to dilute risk.

New norms for promoter contributions

The framework mandates that promoters or acquirers must bring in at least 25% of the acquisition cost as equity. This is a jump from the previous 15% requirement.

Banks must also ensure that the loan tenor does not exceed seven years, with a mandatory amortisation schedule starting from year three. Earlier, some lenders offered bullet repayments at maturity, which the RBI considers risky.

For cross-border acquisitions, the rules require banks to obtain a legal opinion on the enforceability of security in the target's jurisdiction. This adds a layer of due diligence that could delay deal closures.

Impact on lenders and deal flow

Bankers say the new framework will make acquisition finance less attractive for smaller lenders. Large state-run and private banks with robust capital bases are better positioned to absorb the higher capital requirements.

Industry analysts point out that the rules could slow down leveraged buyouts in India. Deals valued at over Rs 500 crore may now require consortium lending to spread risk, increasing coordination costs.

The RBI has not yet clarified whether the framework applies to non-banking financial companies (NBFCs) that offer acquisition loans. Experts expect a separate circular for NBFCs later this year.

Transition period and compliance

Banks have until March 2026 to align their existing acquisition finance portfolios with the new norms. The RBI has advised lenders to submit a board-approved transition plan by September 2025.

Non-compliance will attract a penalty of 0.5% of the loan amount per month of delay. This is a stiff deterrent, given the large ticket sizes involved.

The central bank has also warned against 'evergreening' of acquisition loans through restructuring. Any restructuring must be treated as a default and disclosed to credit bureaus immediately.

The framework is part of a broader push by the RBI to align Indian banking norms with Basel IV standards. The global regulatory shift after the 2008 crisis had left Indian acquisition finance relatively lightly regulated.

What to watch: How banks restructure their existing acquisition loan books before the deadline, and whether the RBI extends similar rules to NBFCs. The next RBI Financial Stability Report, due in December 2025, will likely offer early data on compliance trends.
