Fintech Deep Dive — Monday | October 12, 2026 Focus: Developer & Technical — APIs, shared infrastructure and the systems work hidden behind “interoperability.” Coverage: October 5–12, 2026; reporting checked through 8:30 a.m. IST on October 12. Executive summary Four developments this week point to a common engineering problem: India is making financial infrastructure more portable, but the value of that promise depends on standards, operational ownership and clear failure handling. The RBI has set a December 31 deadline for interoperability among Account Aggregators and for bank deposits to appear in consolidated statements. It has also announced a technical committee for financial markets, though the committee’s remit is not yet operationally defined. Meanwhile, a proposed UPI merchant-fee change has exposed the difficulty of turning category-specific commercial rules into reliable transaction logic. Outside India, Zimbabwe is negotiating to license UPI-based technology for its own shared payment rail; that remains a negotiation, not a launch. ...

Fintech Deep Dive — Monday | October 05, 2026 Focus: Developer & Technical — payment rails, authentication, APIs and infrastructure. Coverage period: September 28–October 5, 2026. Executive summary Four developments this week show Indian fintech technology moving in two directions at once. Bank of India says it has put recurring, user-configured programmable rupee payments live; Apple Pay has arrived, initially on a narrow Axis Bank card-and-device footprint; payment gateways are absorbing that wallet into merchant checkouts; and an RBI deadline for cross-border online card authentication has now passed. One is a new capability in public digital money, two are the integration work around a private card wallet, and one is a compliance control that issuers must implement across the international card channel. ...

Fintech Deep Dive — Monday | September 28, 2026 Last week this column treated Global Fintech Fest follow-through as the story. This week the story has a deadline attached: October 15, the day the UPI MDR framework goes live, is now seventeen days out, and the Sept 21–28 window was when India’s payment ecosystem stopped arguing about whether the fee exists and started building for it. Circular OC-237 turned out to be not a fee but a lookup table — sector, instrument, threshold, mandate-type — and every payment gateway, TPAP, acquirer, broker, and AMC in the country now has to encode it. Meanwhile, two quieter infrastructure stories shipped: NPCI’s BHIM app grew a conversational AI support layer that pointedly cannot touch money, and Upstox imported US equity market access over a broker API instead of building it. The through-line: the rail’s next phase is less about new rails, more about new logic running on the existing ones. ...

Fintech Deep Dive — Monday | September 21, 2026 Last week’s developer column covered what Global Fintech Fest launched. This column is about what happened after the keynote lights went down — the Sept 14–21 window, when launch-week theatre turns into issue trackers, bank-enablement lists, and compliance clocks. The week’s developer news divides cleanly: one protocol got parked at the regulator’s door, one piece of banking hardware went open-source, a credit rail quietly went scheme-scale, KYC plumbing got an API face, and every payment systems team in the country inherited a 30-day migration deadline. ...

Fintech Deep Dive — Monday | September 14, 2026 Global Fintech Fest 2026 ran September 8–11 in Mumbai, and for developers it was effectively a launch week for India’s payment and identity infrastructure. The pattern across the announcements is consistent: the rails are no longer judged only by what they process, but by what they let you build — and increasingly, by how much of the build-test-certify loop the infrastructure itself automates. UPI processed a record 24.51 billion transactions worth ₹29.82 lakh crore in August 2026, and nearly half of all global real-time payment volume now flows through Indian rails. At that scale, the interesting engineering questions are orchestration, certification, and control planes — and that is exactly where this week’s launches landed. ...

Fintech Deep Dive — Monday | September 07, 2026 This is the last full week before Global Fintech Fest 2026 opens in Mumbai (September 8–11), and the pre-GFF announcements tell you exactly what the fest will be about: re-architecting India’s payment stack for actors that aren’t human. The rail itself is getting an agent protocol (NPCI’s Unified Agent Protocol). The storefront in front of the rail is getting an AI discovery layer (Juspay Breeze Universal). The merchant back office is becoming a conversation (Razorpay RAY). And the largest UPI processor in the country is engineering around the one device class the app economy skipped — the feature phone. A Zeta survey released this week supplies the backdrop: 70% of Indian banks now run AI in production, with security and control — not ROI — as the scaling constraint. Here are the five stories that matter for developers and architects. ...

Fintech Deep Dive — Monday | August 25, 2026 Monday’s Developer & Technical lens this week captures a fintech infrastructure layer in transition. Agentic AI is no longer a conference slide — it’s showing up in annual reports and payment rail strategies. IPO-bound companies are revealing their tech stacks. And Global Fintech Fest 2026 is shaping up as a referendum on whether India’s payment stack can absorb three simultaneous paradigm shifts. ...

Fintech Deep Dive — Monday | August 24, 2026 This week’s Developer & Technical theme lands at a pivotal moment. India’s fintech infrastructure is being simultaneously rebuilt from the bottom up (AI foundation models, API governance) and debated at the top (MDR legislation, orchestration wars). Here are the five stories that matter. 1. Razorpay Vulcan: India’s First AI Foundation Model for Payments On August 18, Razorpay launched Vulcan — a transformer-based AI foundation model trained specifically on payments data. Built with NVIDIA’s accelerated computing and AWS cloud infrastructure, Vulcan was trained on nearly 3 trillion data points across 4 billion payments processed on Razorpay’s platform. ...

Fintech Deep Dive — Monday | August 17, 2026 Theme: Developer & Technical — APIs, SDKs, Tech Architecture This week’s Developer & Technical deep dive covers five major stories from the Indian fintech infrastructure layer: NPCI’s new UPI API throttling rules taking effect, the NPCI-NVIDIA sovereign AI foundation model for payments, NPCI-IDRBT’s cybersecurity training MoU, NPCI’s digital KYC push for UPI One World, and Nasscom’s sobering mid-year assessment of fintech API security. Together, these stories paint a picture of an ecosystem scaling up hardening measures — on API rate limits, AI model sovereignty, security certifications, and international onboarding — even as familiar API vulnerabilities persist. ...

Fintech Deep Dive — Monday | August 10, 2026 This Monday deep dive covers Developer & Technical developments in Indian fintech from the past 7 days — APIs, SDKs, platform architecture, and the tools that power India’s digital financial infrastructure. 1. Banking Connect Goes Live: NPCI’s NetBanking 2.0 Rails Get Their First Aggregators This week saw significant momentum behind Banking Connect (also called IBMB — Internet Banking & Mobile Banking), NPCI Bharat BillPay Limited’s interoperable netbanking infrastructure. PayU, in partnership with NPCI Bharat BillPay, formally introduced its Banking Connect integration — a faster, simpler way to make and manage netbanking payments with instant settlements. 1 ...
