The Evolution of Money
Money’s history is a sequence of solutions to the same recurring problem: making exchange, measurement, and saving more convenient. This guide traces that path — from barter and its “double coincidence of wants” problem, through commodity money (cattle, shells, precious metals) and standardised coinage, to paper money and the eventual end of the gold standard in 1971, which made today’s fiat currencies (including the rupee) possible. We cover the Indian rupee’s own journey — the RBI’s establishment in 1935 and the demonetisation episodes of 1978 and 2016 — before tracing the acceleration from cheques and cards to NEFT/RTGS/IMPS and, most distinctively, India’s UPI revolution since 2016. We close with a factual look at what’s next: the RBI’s e₹ (CBDC) pilot since late 2022, and cryptocurrency’s current (non-legal-tender, separately-taxed) status in India — and the common thread running through every step of this history.
