The Race to Digitise Money: Where Central Bank Digital Currencies Stand in 2026

CBDCs come in two structurally different forms, and conflating them is the most common source of confusion in public discussion. Retail CBDC is designed for use by ordinary households and businesses, functioning similarly to digital cash — a direct central bank liability, unlike bank deposits, which are liabilities of commercial banks. Wholesale CBDC, by contrast, is restricted to banks and financial institutions for interbank settlement, essentially modernising the plumbing that already exists between central banks and the commercial banking system. Much of the genuine near-term progress — including in India's own CBDC programme — is happening on the wholesale side, where the case for efficiency gains is clearer and the risks to commercial bank deposit bases are lower.

Retail CBDC faces a harder adoption problem, and India's experience illustrates why. The RBI launched its e-Rupee retail pilot in December 2022, expanding steadily across cities and use cases since. Circulation has grown quickly in percentage terms — up 334% to roughly ₹10.16 billion by March 2025 — but this remains a tiny fraction of the value processed monthly through the Unified Payments Interface (UPI), India's real-time payment system that already gives most Indians a fast, free, widely-accepted digital payment option. When an alternative already solves the problem a new technology is meant to solve, adoption inevitably lags, regardless of the new technology's other merits.

This has pushed the RBI's 2026 strategy toward differentiation rather than raw volume competition. Two features stand out. First, offline functionality using near-field communication (NFC) technology, allowing e-Rupee transactions without an active internet connection — directly useful in India's more remote regions where connectivity is patchy, a genuine gap UPI cannot fully address. Second, ‘programmability’: the ability to restrict how a specific digital rupee can be spent, which has direct application to targeted government transfers such as fertiliser subsidies, education scholarships, or disaster relief, where authorities want assurance that funds reach their intended purpose rather than being diverted.

The broader global picture shows similar patterns of pilot-stage caution. China's digital yuan (e-CNY) has the most extensive retail rollout globally, integrated into some government payroll and transit systems, yet even there transaction volumes remain modest relative to existing mobile payment platforms. The European Central Bank continues preparatory work on a digital euro but has not committed to a launch date, partly due to unresolved concerns from commercial banks about deposit disintermediation — the risk that if a CBDC becomes an attractive alternative to a bank deposit, funds could flow out of the banking system during periods of stress, amplifying rather than dampening financial instability.

For 2026-2028, the more plausible near-term trajectory across most CBDC programmes, India's included, looks like continued pilot expansion, deeper wholesale CBDC integration for interbank settlement, and selective retail use in specific channels like targeted government transfers — rather than a wholesale replacement of existing payment systems. The strategic case for persisting, even amid modest retail adoption, rests less on near-term transaction volume and more on maintaining monetary sovereignty and payment system resilience as private and foreign digital payment alternatives continue to expand their reach.
