08 — Innovation: How Money Dematerialised, 1971–2026

Parallel monetary and technological changes

The US suspension of official dollar-to-gold convertibility in 1971 occurred alongside developments in computing and electronic markets. Those dates describe parallel changes, not a shared cause. Bank deposits and payment instructions could already be recorded and communicated without moving coins; the legal promise behind a monetary claim and the technology that records or transfers it are separate questions. Floating exchange rates changed some risks firms faced, while computing and communications technology opened other ways to organise trading and payments. Later digital tokens and Bitcoin posed still different questions about issuers, settlement and redemption. This chapter follows those distinct paths rather than assigning financial innovation as a whole to the 1971 gold-window decision.

Managing the new risks: derivatives (1972–2000)

The move from Bretton Woods' adjustable pegs to floating exchange rates changed the pattern of currency risk, and derivatives grew as one way to hedge it. The pegs had still allowed devaluations and interest-rate changes. Federal Reserve History, “Launch of the Bretton Woods System”. Currency futures began at the Chicago Mercantile Exchange in May 1972 (Leo Melamed, advised by Milton Friedman, who was paid $7,500 for a supporting paper); listed stock options at the Chicago Board Options Exchange in April 1973; Fischer Black and Myron Scholes published their pricing paper on 1 May 1973; Treasury futures in 1977; stock-index futures in 1982; and the World Bank's first formal currency swap with IBM in 1981. The Bank dates its own first interest-rate swaps to 1985. World Bank Treasury, “1981: Bank Executes First Currency Swap”. The International Swaps and Derivatives Association (1985) standardised the contracts. JPMorgan's team invented the credit default swap in 1994 and popularised value-at-risk models; collateralised debt obligations followed. By 2008 the notional value of over-the-counter derivatives was $600 trillion, ten times world GDP. Portfolio insurance caused the 1987 crash, LTCM's swaps nearly caused one in 1998, and credit default swaps on subprime mortgages caused the real one in 2008 — each crisis a derivative of the instruments invented to manage the risks of fiat money.

Moving money: from SWIFT to real-time payments (1973–2023)

Electronic payments developed in distinct layers. CHIPS began clearing large-dollar interbank payments in 1970; Swift was founded in 1973 and began carrying standardized bank messages in 1977. A Swift instruction is not a transfer of funds or final settlement: the receiving and correspondent banks and the relevant payment system must still act on it. Card networks add a different sequence: a merchant may receive a rapid authorization, then the transaction is cleared and the banks settle later. By contrast, a participating US bank can use the FedNow service to offer around-the-clock instant payments with immediate funds availability; participation, access and the customer-facing service still matter. UPI and Pix are further domestic instant-payment arrangements, not measures of Swift's settlement speed. None of these rails can be ranked by one “transactions per second” or uptime figure without specifying which stage, geography, institutions and period are being measured.

Financialising gold: the ETF (2003–04)

Gold-backed exchange-traded products gave investors a way to trade a security linked to vaulted gold holdings through a brokerage account. Australia's Gold Bullion Securities began exchange quotation in March 2003; SPDR Gold Shares (GLD) listed in the US on 18 November 2004. A GLD share represents a fractional interest in a trust that holds gold, whose objective is to reflect the bullion price less trust expenses. An ordinary share investor cannot demand delivery of one ounce: the prospectus restricts creation and redemption to authorised participants in large baskets. The security is neither a banknote nor direct possession of a particular bar. GLD's published expense ratio is 0.40%, and its fund overview names the trust's custodians. ASX, March 2003 official-quotation notice; SPDR Gold Shares, fund overview and listing information; SPDR Gold Trust prospectus, cover and “Trust Structure”. The World Gold Council estimates that global gold-backed ETF holdings peaked at 3,929 tonnes in November 2020 and that the “ETFs & Similar Products” sector's holdings grew by a net 801.2 tonnes during 2025. That annual stock change is not a count of retail purchases or a named fund's inflow.

Money without an issuer: Bitcoin (2008–)

Satoshi Nakamoto published the Bitcoin whitepaper on 31 October 2008, and the network began in January 2009. It offers a publicly verifiable issuance schedule and ledger without a central issuer; confidence in a payment grows with confirmations rather than becoming absolutely irreversible. Exchanges, custodians and payment layers later developed around that base system. El Salvador's 2021 law required Bitcoin acceptance alongside the U.S. dollar. Decree 199, adopted in January 2025 and effective 90 days after publication, amended rather than repealed that law: private acceptance became voluntary, Bitcoin tax-payment authority was removed, and the domestic text retained “curso legal” wording. Decree 199, arts. 1–8. The IMF calls this removal of the essential features of legal tender. IMF Country Report 25/58, para. 27 n.18. These changes did not make Bitcoin the general unit of prices or wages.

Whether Bitcoin is money is still argued. It is not a unit of account (nothing is priced in it), it is a poor medium of exchange (slow, volatile, taxed as property), but it has functioned for sixteen years as a store of value that no state controls, which is the one job gold does that fiat cannot. It is best understood as the fiat era's attempt to rebuild the properties of gold in software, and the fact that it was invented in the month the banks were bailed out says what its inventor thought of fiat.

The digital dollar by accident: stablecoins (2014–)

Dollar-denominated stablecoins add a token-transfer layer to the existing payment system. Tether and USDC began as ways to move dollar claims within crypto markets; some users now send them across borders. But a blockchain transfer may be a merchant payment, an exchange deposit, a trading or DeFi operation, a bridge movement, a mint or redemption, or a treasury sweep. Visa's on-chain dashboard distinguishes gross from adjusted volume and categorizes payments separately; its filters are estimates based partly on labelled addresses and heuristics. Neither gross nor adjusted volume is automatically equivalent to Visa purchases or ACH settled payments, and the earlier “more than Visa / half of ACH” comparison is withheld. To evaluate a stablecoin remittance, count local-currency purchase, issuer or wallet restrictions, blockchain fee, possible intermediary and exchange spreads, recipient cash-out, time to usable funds and recourse. A transfer can be available outside banking hours while one or both conversion legs are not. Issuer reserve quality and redemption rights also depend on the named token and applicable law, not on the word “stablecoin.” Visa Onchain Analytics, adjusted-volume methodology and use-case categories; World Bank remittance-cost methodology.

The state's answer: central-bank digital currencies (2020–)

Central-bank digital currency projects explore different payment and settlement arrangements. The Bahamas launched the Sand Dollar in 2020; Nigeria's eNaira and China's e-CNY have different access and operating designs. The BIS's mBridge project tested cross-border transfers and settlement between participating central banks in digital currencies. Swift, by contrast, carries messages; the underlying claims settle through other institutions and systems. A pilot does not itself show broad production adoption, customer access or final end-to-end costs. As of September 2026, the digital euro is still proposed: the ECB expects a pilot in the second half of 2027 and says possible issuance in 2029 depends on legislation and a later decision to issue. Its proposed design uses supervised intermediaries, online and offline functions, no interest and holding limits; these are design choices under development, not features of an issued currency. BIS, mBridge project; ECB, digital-euro progress and decision sequence; ECB, design FAQs.

A retail CBDC would be a digital central-bank liability, but its access, privacy, remuneration, offline capability and limits depend on the named design. Those choices should be evaluated from the actual proposal rather than assumed from the label. The ECB, for example, proposes no interest and holding limits for a possible digital euro, and says offline functionality is intended to protect payment privacy. ECB, digital-euro FAQs.

Innovation's effect on the monetary system

Many contemporary monetary claims are recorded and transferred electronically, but a fast message is not necessarily a cheap or final payment. Digital rails have changed who can send, receive, trace or restrict transfers; their costs and protections vary by institution, corridor and instrument. QE is a central-bank asset purchase with matching balance-sheet entries, not simply a keystroke creating unencumbered spending power. Stablecoins and Bitcoin create new arrangements for holding and transferring claims, with different issuers, custody and recourse. Physical gold remains a distinct asset, even when investors buy a fund share representing a claim on vaulted metal.

Key takeaways

Electronic payment systems separate instructions, authorization, clearing, settlement and access to usable funds. Swift messages, card authorizations, instant bank payments and on-chain token transfers therefore answer different questions. Stablecoin transfers can move dollar-denominated claims across blockchains, but gross on-chain volume includes trading and internal movements; it is not retail spending or a settled card-network equivalent. Whether a rail is faster or cheaper depends on the entire payment path, participating institutions, currency conversion, operating hours and recourse. CBDC projects test still other designs, while Bitcoin's base layer and Lightning have different capacity, custody and liquidity constraints.
