RBI Deputy Governor Lays Out Five Tests for Responsible AI in Banking
RBI Deputy Governor Shirish Chandra Murmu delivered a keynote on August 19 — “A Vision for Responsible AI, Resilient Banking” — laying out five supervisory expectations for banks deploying AI: Include, Adapt, Understand, Safeguard, Explain.
The core message: a machine may reach a decision, but a person must own it. Banks remain accountable even when models come from fintech partners or third-party vendors. Customers must be told when an automated system made a decision, given an understandable explanation, and have access to a human reviewer with authority to reverse it.
The speech also flagged a worrying data point: despite 14% commercial credit growth, the share of new businesses entering formal credit fell from 52% in 2022–23 to 42% in 2025–26. Murmu urged banks to use AI and alternative data (GST filings, utility payments, agricultural patterns) to serve “credit invisibles” rather than just cut costs. On the systemic front, he warned that shared AI models, cloud providers, and data sources create concentration risk — a single error could cascade across multiple institutions.
This aligns with SEBI Chairman’s same-day address proposing tiered AI/ML rules with human-in-the-loop controls and kill switches. Both regulators are converging on one principle: the regulated entity owns the outcome, regardless of who built the model.

Navi Raises $100M from Prosus at ~$1.3B Valuation, Pre-IPO
Sachin Bansal’s fintech Navi has raised $100 million from Dutch tech investor Prosus NV — its first institutional funding round in eight years. The deal values the Bengaluru-based lender at approximately $1.3 billion.
Bansal founded Navi in 2018 after exiting Flipkart and has primarily self-funded the venture, pouring hundreds of millions of his own money into building what he intends to become a full-stack bank. The company offers personal loans, home loans, mutual funds, and health insurance. The Prosus investment is positioned as a pre-IPO round, with Navi reportedly planning a public listing.
Notably, Navi had sought $2 billion valuation from institutional investors in 2024. The $1.3 billion mark represents a significant haircut from those ambitions, reflecting both broader fintech valuation resets and Navi’s specific growth trajectory.
UPI MDR Debate Resurfaces as President Signs Taxation Amendment Bill
The President has approved the Taxation and Other Laws (Amendment) Bill, 2026, paving the way for potential charges on UPI transactions — a move that has reignited the debate over whether India’s most popular payment rail should remain free for consumers.
Currently, banks and payment system providers cannot charge users for UPI or RuPay debit card transactions. Santanu Paul, former NPCI director and co-author of upcoming book Cashless Nation, warned that while UPI’s success is directly linked to its zero-cost model, the system lacks a sustainable business model to support its next phase of growth — potentially five-fold in the coming decade.
The amendment alone doesn’t impose charges; it creates the legislative runway for the government to introduce a merchant discount rate (MDR) framework. The RBI’s draft UPI MDR framework, referenced by Deputy Governor Murmu, remains pending with concrete details yet to be published.
Qatar-India UPI Remittance Corridor Goes Live
India Post, Qatar Post, the Universal Postal Union’s Interconnection Platform, and NPCI International Payments Limited (NIPL) have launched PosTransfer — a UPI-powered remittance service enabling instant money transfers from Qatar to India.
The service combines the physical reach of postal networks with India’s digital payment infrastructure, giving Indian expatriates in Qatar a new real-time channel for sending money home directly to UPI-linked bank accounts. This follows similar UPI internationalisation pushes with the Maldives and other countries, as India leverages its DPI for diplomatic and economic outreach.
