India plans common customer ID for banks, insurers, mutual funds

India moved toward a common customer identification system for banks and insurers, with mutual funds set to follow, in a phased effort to cut repeated onboarding checks across a fast-growing financial system. The plan would make it easier for lenders and insurers to verify the same customer across products while reducing the paperwork that often slows account opening and policy sales.

The proposal targets know-your-customer rules that have long forced customers to submit similar documents to different parts of the industry. A shared identifier could let institutions maintain a consistent profile for one person across bank accounts, insurance policies and mutual fund investments, reducing duplication and making fraud screening more efficient. It could also lower friction for first-time users, especially in smaller towns and rural areas where lengthy documentation can discourage formal financial participation.

The push comes as India’s financial architecture has become more interconnected. The International Monetary Fund said in its 2025 Financial Sector Assessment Program executive summary that India’s financial system had become more resilient and diverse, with non-bank financial institutions and market financing growing. That shift makes a common customer ID more relevant, because more firms are dealing with the same households across multiple products and channels.

The proposal also underscores a tradeoff that has defined many of India’s digital finance reforms: efficiency versus surveillance. A single identity layer could improve compliance, help regulators detect suspicious activity and give institutions a cleaner view of customer exposure. But it would also concentrate sensitive personal data in one system, raising questions about privacy, data governance, interoperability and who controls the underlying identifier. Those concerns will matter as much as the technical design, because a shared ID is only as secure as the rules around access, storage and reuse.

The rollout would begin with banks and insurers, then extend to mutual funds, signaling an incremental approach rather than an immediate sector-wide switch. Separate reporting also pointed to CKYC 2.0 launching in August for banks and insurers, suggesting the new framework could build on India’s existing Central KYC infrastructure instead of replacing it outright.

For regulators, the attraction is clear: fewer repeated checks, cleaner records and a more unified customer profile across the financial system. For consumers, the promise is less friction. The challenge is making sure a tool designed to simplify access does not become another layer of data concentration in one of the world’s largest and most digitized financial markets.
