New on FinoLib · Volume I: Global Economy
New on FinoLib, my finance education website: I have published an article called UPI, India’s Informal Economy, Remittances and GCCs, from Volume I: Global Economy. Here is what the article explains, written as a short expert briefing; the full piece, with every worked example, is one click away.
10.3 UPI and Digital Public Infrastructure — India’s Payments Revolution
The idea in plain words
India built UPI in 2016 on the JAM base of Jan Dhan accounts, Aadhaar identity and mobile phones, as a public, interoperable, free-to-user rail on which private apps compete.
Key points
■The JAM trinity comprises 500M+ Jan Dhan basic bank accounts opened from 2014 and 1.3B+ biometric Aadhaar IDs enabling instant KYC.
■Adoption became vertical after the 2016 demonetization, which invalidated roughly 86% of India’s currency in circulation, and after COVID’s shift to contactless payment.
A closer look
Chapter 3.12: Digital Money — Cryptocurrency, Stablecoins, and CBDCs covered crypto and CBDCs; the more consequential digital-money revolution happened in India, built not on blockchain but on public infrastructure. The foundation was the JAM trinity: Jan Dhan (500M+ basic bank accounts opened from 2014), Aadhaar (1.3B+ biometric IDs enabling instant KYC — recall how identity verification gates every account in Part 3: Banking & Financial System), and Mobile. On that base, the NPCI — a non-profit owned by banks under RBI oversight — launched UPI in 2016: an open protocol letting any app move money between any two bank accounts instantly, 24×7, using just a virtual ID or QR code.
10.4 The Informal Economy — India’s Invisible Majority
The idea in plain words
About three in four Indian workers are self-employed or casual laborers, and agriculture employs about 42% of workers while producing about 16% of GDP. Monsoons and minimum support prices tie farming to food inflation, and informal credit sits outside the reach of the repo rate.
Key points
■Self-employed and casual workers were 55.8% and 18.9% of workers in the latest survey quarter cited by the Economic Survey 2025-26.
■Agriculture produced 16.2% of GDP in 2025 with about 42% of workers, so output per farm worker is roughly a quarter of the rest of the economy’s.
A closer look
The informal economy is the street vendor, the construction crew hired daily at a labor chowk, the kirana shop, the domestic worker, the gig rider hovering between categories, the unregistered workshop with six employees. Informality here means operating outside registration, labor law, and social security — not illegality of the work itself. The scale inverts the usual mental picture: the corporate India of Parts 4–6, with its exchanges and annual reports, directly employs only a small minority of Indian workers; agriculture alone still employs about 42% (Economic Survey 2025-26, from the PLFS labor-force survey for July–September 2025).
10.5 Remittances — The ₹10 Lakh Crore Lifeline
The idea in plain words
Remittances to India were $150.7 billion in 2025, 3.8% of GDP and about 3.9 times net FDI inflows. They sit in the balance of payments as secondary income and often hold up when the home economy weakens.
Key points
■India is the world’s #1 recipient, with 2025 receipts up 9.4% from $137.7 billion in 2024; at any rate above ₹66 per dollar the total exceeds ₹10 lakh crore.
■Remittances exceed a quarter of GDP in Nepal (26.0% in 2024) and approach 40% in Tonga (39.2%).
A closer look
A remittance is the most human transaction in this guide: a nurse in Dublin, a welder in Dammam, or an engineer in San Jose sending part of a salary home. Summed, these transfers make India the world’s #1 recipient — $150.7 billion in 2025 (up 9.4% from $137.7 billion in 2024), 3.8% of GDP and about 3.9 times net FDI inflows of $39.1 billion. At any exchange rate above ₹66 per dollar that is more than ₹10 lakh crore (₹10 lakh crore ÷ $150.7 billion ≈ ₹66.4 per dollar), the lifeline of this chapter’s title. In the balance of payments (chapter 1.13: Balance of Payments — The Complete Money-Flow Picture) they sit as secondary income, quietly offsetting a large slice of the trade deficit; Kerala’s economy has run on Gulf remittances for two generations.
10.6 From BPO to GCC — India’s Global Delivery Economy
The idea in plain words
India’s delivery economy moved from BPO outsourcing to captive centers to Global Capability Centers, which are now financial infrastructure rather than a cost line.
Key points
■More than 1,700 GCCs employed about 19 lakh (1.9 million) Indian professionals as of FY2023-24.
■BPO took call centers and back-office processing from the late 1990s, and GE’s 1997 India captive was the early example of a global firm owning the operation.
