From Hundi to UPI

How Hundi principles of trust, interoperability, and low cost inspire India's digital payment revolution and offer lessons for global financial systems.

Relevance in 2026 and Beyond

Modern Hook

You send ₹10,000 to your cousin in Bangalore through UPI. Within seconds, the money arrives, zero fees, instant confirmation, no middlemen visible. Now try sending that same amount to your uncle in London. Suddenly, you're navigating wire fees, currency conversion charges, correspondent bank delays, and a wait time measured in days, not seconds.

Why does moving money across a digital network within India cost nothing, while the same operation across borders extracts 5-7% in fees? The answer lies in principles that Indian merchants understood five centuries ago, and that we're only now rediscovering.

The Modern Challenge

Global remittances in 2024 topped $860 billion, with migrant workers sending money home to families across the developing world. Yet the World Bank reports that the average cost of sending $200 remains around 6.2%, meaning billions of dollars are extracted from the world's poorest populations every year.

The SWIFT network, built in 1973, remains the backbone of international transfers. Despite processing over 45 million messages daily across 11,000 institutions, it still takes 2-5 days for a standard international transfer. Each hop in the correspondent banking chain adds fees and delays.

Meanwhile, India's UPI processed over 13 billion transactions per month by late 2024, more than all U.S. card networks combined. The cost? Effectively zero for consumers. The National Payments Corporation of India (NPCI) has begun exporting this model: UPI now works in Singapore, UAE, France, and other countries.

What made this possible? Not just technology, other countries have technology. The difference lies in architecture, and that architecture echoes something ancient.

The Ancient Insight

The Hundi system, as we've explored in this chapter, operated on principles that seem remarkably modern:

Trust networks over centralized control. Hundis worked because Shroffs and Seths formed interconnected networks. A Hundi issued in Ahmedabad could be honored in Calcutta because the drawer's reputation was known across the network. No single authority validated transactions, the network itself was the verification system.

Interoperability through standardization. Despite regional variations, Hundis followed recognizable patterns. A Darshani Hundi worked the same whether issued by a Marwari Seth or a Gujarati Shroff. Merchants across the subcontinent understood the instrument.

Minimal friction, minimal extraction. Batta fees on Hundis typically ranged from 0.5% to 2%, a fraction of what hawala or Western Union charges today. The system minimized intermediaries, reducing costs.

Reputation as infrastructure. The Vishwasa-Tantra (trust infrastructure) we examined wasn't metaphorical, it was the actual mechanism that enabled Hundis to function. Community enforcement made formal contracts unnecessary.

The Bridge

UPI's architects, whether consciously or not, implemented these ancient principles using modern technology.

Trust networks over centralized control. UPI doesn't route all transactions through a single bank. Instead, it creates a network of banks connected through standardized protocols. The Immediate Payment Service (IMPS) infrastructure allows any bank to communicate with any other. Like Hundi networks, no single point controls everything.

Interoperability through standardization. UPI created a universal interface, a single specification that all banks must implement. Just as Hundis had standard formats despite issuer variation, UPI has a standard API despite bank variation. Your phone number or virtual payment address works across all banks.

Minimal friction, minimal extraction. NPCI operates as a non-profit, extracting no transaction fees from consumers. The fee structure for merchants is among the lowest in the world. This echoes the Hundi system's efficiency: keep costs low by keeping intermediaries few.

Reputation as infrastructure. UPI uses mobile numbers and Aadhaar as identity anchors, creating a digital version of the reputation networks that Hundis relied on. The 'trust' is now cryptographic rather than social, but the function is similar.

The parallels extend to India's international payment ambitions. The Rupee Trade Settlement mechanism launched in 2023 allows India and partner countries to settle trade in rupees, bypassing dollar-denominated SWIFT transactions. This echoes how Hundis allowed settlements across regions without physically moving precious metals.

Addressing Skepticism

"But informal systems like Hundis also enabled tax evasion and money laundering," skeptics might argue. This is accurate. The same features that made Hundis efficient, minimal documentation, community-based verification, lack of formal oversight, also made them attractive for illicit purposes. The British colonial government's 1881 Negotiable Instruments Act was partly aimed at bringing these systems under legal control.

The lesson isn't that we should return to informal systems, but that we should understand why they worked so efficiently, then build formal systems that capture those efficiencies while adding appropriate oversight.

UPI achieves this: every transaction is logged, traceable, and subject to regulatory review. Yet the user experience remains as frictionless as a Hundi. The lesson from history isn't to abandon regulation, it's to design regulation that doesn't destroy efficiency.

"These are just surface similarities," another objection runs. "You're retrofitting modern concepts onto ancient practices." There's validity here. The Hundi system wasn't designed by economists with optimization theory. It evolved organically over centuries.

But that's precisely what makes the parallels significant. These principles, network trust, standardized interfaces, minimal extraction, emerge naturally when commerce must work across distances without centralized control. The Hundi merchants discovered them empirically; modern payment architects rediscover them theoretically. Both arrive at similar solutions because the underlying problem, moving value across a trust-sparse environment, remains constant.

Call to Practice

What can you do with this understanding?

In your professional life: If you work in fintech, payments, or banking, study Hundi mechanics not as history but as case studies. How did they handle disputes? What was their equivalent of chargebacks? The answers might inform modern product design.

In your financial choices: Prefer payment systems that minimize intermediaries. Understand why UPI works and expensive alternatives persist, often it's regulatory capture, not technical necessity.

In your worldview: Recognize that financial innovation isn't a Western monopoly. India's payment infrastructure now leads the world, drawing on indigenous traditions of commercial organization. This pattern, ancient wisdom informing modern innovation, appears across domains.

The Hundi system declined under colonial rule, but its principles survive. In every UPI transaction, there's an echo of the trust networks that once spanned the subcontinent. Understanding that heritage isn't just academic, it's the foundation for imagining what comes next.
