SBI to Tap UPI Data for Lending to Small Businesses Without GST Registration

State Bank of India, the country's largest lender, is building a new lending solution that would use UPI transaction data as a stand-in for sales records to extend credit to small businesses that lack Goods and Services Tax (GST) registration, according to Managing Director Ashwini Kumar Tewari.

UPI as a Substitute for GST Data

Speaking at the Global Fintech Fest, Tewari said the bank is developing what he called "the UPI solution without GST," built on the idea that regular digital payment flows through UPI can serve as a reliable proxy for a business's actual sales activity when formal GST records don't exist. SBI already runs automated lending for GST-registered small businesses, processing loans in about 10 minutes using GST filings, PAN details and other digital records; the bank has disbursed roughly Rs 1 trillion through this channel over the past year and a half.

The remaining friction even for GST-registered borrowers, Tewari said, is a mandatory site visit to confirm the business physically exists, a step he said banks still need because purely digital checks can be gamed. For businesses without GST registration, however, UPI transaction history could offer a comparable digital trail of sales activity that underwriters can use in its place, subject to customer consent.

Targeting the Micro-Business Funding Gap

Tewari framed the initiative as part of a broader shift in Indian banking from balance-sheet-based lending toward cash-flow-based lending, so long as that cash flow moves through traceable digital channels rather than physical cash. He said the goal is to build a financial profile of a small business from its spending and revenue patterns even when formal revenue documentation is sparse or irregular, specifically to reach India's smallest, most under-financed micro-enterprises. "Unless we solve for micro, this segment doesn't get solved," he said, describing the gap in MSME funding as a persistent structural problem.

As a complementary idea, Tewari suggested that small-value transactions of up to Rs 100 could eventually be routed through digital wallets rather than the core banking rails, easing pressure on banking infrastructure as digital transaction volumes keep climbing. He also floated voice-based, multilingual, AI-driven lending interfaces that would let customers request a loan in plain language, with the system translating that request into the bank's underwriting process automatically.

What It Could Mean

If SBI's UPI-based underwriting model works at scale, it could open formal credit access to a large segment of India's small and micro businesses that currently sit outside the GST net entirely, either because they fall below GST registration thresholds or operate informally. It would also mark a meaningful shift in how Indian banks think about creditworthiness, leaning more heavily on real-time digital transaction behaviour rather than static financial statements. For now, the solution remains under development, and SBI has not detailed a launch timeline.
